[0044] Based on the wire marking tube printer in this application embodiment, this application embodiment sets a curved tube path, causing the wire marking tube to bend and extend at the first channel and / or the second channel. The wire marking tube at the bend abuts against the conveying component and / or the printing component, so there is a force between the wire marking tube and the conveying component and / or the printing component. That is to say, compared with the straight path, in the curved path, the wire marking tube needs to bear the force at the conveying component and / or the printing component. This keeps the wire marking tube part in the wire marking tube printer in a taut state, which can reduce the possibility of the wire marking tube loosening during the movement of the wire marking tube printer, thereby reducing the problem of poor contact of the wire marking tube inside the wire marking tube printer.

[0106] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0107] Example 1

[0108] Please refer to Figures 1-3. This application proposes a wire marking tube printer 1 configured to print on wire marking tubes 2. The wire marking tube printer 1 includes a main unit 10, a conveying component 20a, and a printing component 30. The main unit 10 has a receiving cavity, and the conveying component 20a and the printing component 30 are both disposed in the receiving cavity of the main unit 10. The inlet 11c and the outlet 12a are both connected to the receiving cavity. The wire marking tube 2 extends into the receiving cavity from the inlet 11c, passes through the conveying component 20a and the printing component 30, and extends out from the outlet 12a. The receiving cavity of the main unit 10 provides installation space and a base for the conveying component 20a and the printing component 30. The conveying component 20a can be configured to convey the wire marking tube 2, allowing the wire marking tube 2 to move and print in the wire marking tube printer 1. The printing component 30 can be configured to print characters on the outer wall of the wire marking tube 2.

[0109] The host 10 has an inlet 11c and an outlet 12a, both of which are configured to allow the wire number tube 2 to pass through. The conveying component 20a is located between the inlet 11c and the outlet 12a, and has a first channel 21 for the wire number tube 2 to pass through. The printing component 30 is located between the conveying component 20a and the outlet 12a, and has a second channel 31 for the wire number tube 2 to pass through. The inlet 11c, the first channel 21, the second channel 31 and the outlet 12a are arranged in sequence to form a tube path 13 for the wire number tube 2 to pass through, and the tube path 13 for the wire number tube 2 is curved.

[0110] It should be noted that the wire tube 2 enters the main body from the inlet 11c, passes through the first channel 21 and the second channel 31 in sequence, and finally extends out from the outlet 12a. The wire tube 2 moves and prints in the wire tube printer 1. At this time, the wire tube 2 extends in a curved shape in the tube path 13. The wire tube 2 bends and extends at the first channel 21 and / or the second channel 31. The wire tube 2 at the bend abuts against the conveying component 20a and / or the printing component 30. Therefore, there is a force between the wire tube 2 and the conveying component 20a and / or the printing component 30. That is to say, compared with the straight path, in the curved path, the wire tube 2 needs to bear the force at the conveying component 20a and / or the printing component 30. This keeps the part of the wire tube 2 in the wire tube printer 1 in a taut state, which can reduce the possibility of the wire tube 2 loosening during the movement of the wire tube printer 1, thereby reducing the problem of poor contact of the wire tube 2 inside the wire tube printer 1.

[0111] Please refer to Figures 2-3. In some embodiments of this application, the conveying assembly 20a includes a conveying roller 22 and a floating roller 23. The conveying roller 22 is rotatably connected to the host 10. The conveying roller 22 and the floating roller 23 are arranged opposite to each other, and a first channel 21 is formed between the conveying roller 22 and the floating roller 23.

[0112] It is easy to understand that the first channel 21 is located between the conveyor roller 22 and the floating roller 23. The wire marking tube 2 passes through the first channel 21. Both the conveyor roller 22 and the floating roller 23 can provide a limiting function for the wire marking tube 2. When the wire marking tube 2 passes through the first channel 21, it comes into contact with the conveyor roller 22. During the rotation of the conveyor roller 22, due to the friction between the conveyor roller 22 and the wire marking tube 2, the friction can drive the wire marking tube 2 to move along the tube path 13.

[0113] Furthermore, the floating roller 23 is movably connected to the main unit 10, allowing the floating roller 23 to move relative to the main unit 10 and change the size of the first channel 21. That is, when the wire tube 2 passes through the first channel 21, the floating roller 23 can move closer to the conveyor roller 22, thus reducing the size of the first channel 21. This means the wire tube 2 is clamped within the first channel 21, increasing the friction between the conveyor roller 22 and the wire tube 2, allowing the conveyor roller 22 to move the wire tube 2 more smoothly. Since the wire tube 2 is clamped by both the conveyor roller 22 and the floating roller 23 when passing through the first channel 21, there is also friction between the wire tube 2 and the floating roller 23. In some embodiments, the floating roller 23 can also be rotatably connected to the main unit 10, so that the friction between the floating roller 23 and the wire tube 2 can also drive the wire tube 2 to move along the tube path 13.

[0114] As shown in Figures 2 and 3, the printing assembly 30 includes a printing roller 32 and a printing element 33. The printing roller 32 is rotatably connected to the host 10. The printing roller 32 and the printing element 33 are arranged opposite to each other, and a second channel 31 is formed between the printing roller 32 and the printing element 33.

[0115] As is easily understood, the second channel 31 is located between the printing roller 32 and the printed part 33. The marking tube 2 passes through the second channel 31, and both the printing roller 32 and the printed part 33 can provide a limiting function for the marking tube 2. When the marking tube 2 passes through the second channel 31, it comes into contact with the printing roller 32. During the rotation of the printing roller 32, due to the friction between the printing roller 32 and the marking tube 2, the friction can drive the marking tube 2 to move along the tube path 13. At the same time, the printed part 33 prints characters on the marking tube 2.

[0116] Furthermore, the printout 33 can also be movably connected to the host 10 so that the printout 33 can move relative to the host 10 and change the size of the second channel 31. That is, when the wire tube 2 passes through the second channel 31, the printout 33 can move towards the printing roller 32 so that the range of the second channel 31 is reduced, that is, the wire tube 2 is clamped in the second channel 31, so that the printout 33 can print characters on the wire tube 2 more smoothly.

[0117] For example, as shown in Figures 2-3, the axis lines of the conveyor roller 22, the floating roller 23, and the printing roller 32 can all extend vertically. This ensures that when the wire marking tube 2 passes through the first channel 21, the periphery of the conveyor roller 22 and the floating roller 23 does not need to bear the weight of the wire marking tube 2, and the frictional force between the conveyor roller 22, the floating roller 23, and the wire marking tube 2 is the same. Similarly, when the wire marking tube 2 passes through the second channel 31, the periphery of the printing roller 32 and the printed part 33 does not need to bear the weight of the wire marking tube 2, thus avoiding the influence of the wire marking tube 2's own gravity. Since the conveyor roller 22 and the printing roller 32 are rotatably mounted on the host 10, they can be located on the same side of the tube path 13. Similarly, the floating roller 23 and the printed part 33 are movably mounted on the host 10, so they can also be located on the same side of the tube path 13. This reduces motion interference between the conveyor assembly 20a and the printing assembly 30.

[0118] Please refer to Figure 2. In some embodiments of this application, the wire marking printer 1 further includes a ribbon cartridge 40 disposed on the host 10. The ribbon cartridge 40 is located on the side of the printable part 33 away from the print roller 32. The ribbon cartridge 40 includes a ribbon sleeve (not shown in the figure), which is sleeved on the printable part 33.

[0119] The distance from the ribbon cartridge 40 to the print head 33 is less than the distance from the ribbon cartridge 40 to the printing roller 32, thus allowing the ribbon sleeve on the ribbon cartridge 40 to better connect with the print head 33 and preventing the printing roller 32 from interfering with the connection between the ribbon sleeve and the print head 33. The print head 33 can be a thermal print head, with the ribbon sleeve fitted onto it. The thermal print head has a row of heating resistors. During printing, these heating resistors contact the marking tube 2. When a certain current passes through these heating resistors, they quickly generate high temperatures. Under certain pressure, when the toner on the ribbon sleeve contacts these heating resistors, the temperature rises in a very short time, and the toner prints characters on the marking tube 2.

[0120] Furthermore, as shown in Figure 3, the distance between the first channel 21 and the printing roller 32 is less than the distance between the first channel 21 and the printed part 33. That is to say, after the wire tube 2 passes through the first channel 21, the wire tube 2 will first contact the printing roller 32, and then contact the printed part 33 when passing through the second channel 31. It can be understood that the wire tube 2 extends from the first channel 21 to the second channel 31, and the wire tube 2 bends at the second channel 31. At this time, the printing roller 32 is located inside the bending path, and the printed part 33 is located outside the bending path. That is to say, the wire tube 2 will turn around the circumference of the printing roller 32, and the printed part 33 contacts the wire tube 2 along the tangent direction of the printing roller 32, thereby reducing the contact area between the wire tube 2 and the ribbon sleeve on the printed part 33, so as to reduce the friction between the wire tube 2 and the ribbon sleeve, thereby greatly reducing the situation where the wire tube 2 wipes off the toner on the ribbon sleeve.

[0121] Please refer to Figures 3-4. In some embodiments of this application, the shortest distance from the side of the conveyor roller 22 to the ribbon cartridge 40 is L1, and the shortest distance from the side of the printing roller 32 to the ribbon cartridge 40 is L2. The perpendicular distance between the side of the conveyor roller 22 near the ribbon cartridge 40 and the side of the ribbon cartridge 40 near the wiring path is the shortest distance from the side of the conveyor roller 22 to the ribbon cartridge 40, and the perpendicular distance between the side of the printing roller 32 near the ribbon cartridge 40 and the side of the ribbon cartridge 40 near the wiring path is the shortest distance from the side of the printing roller 32 to the ribbon cartridge 40. Since the outer diameter of the conveyor roller 22 is smaller than the outer diameter of the printing roller 32, and the distance between the axis of the conveyor roller 22 and the ribbon cartridge 40 is greater than the distance between the axis of the printing roller 32 and the ribbon cartridge 40, L1 is greater than L2. That is to say, after the wire tube 2 passes through the first channel 21 of the conveyor assembly 20a, the wire tube 2 enters the second channel 31 of the printing assembly 30 at an angle relative to the ribbon cartridge 40, which is conducive to forming a curved tube path 13.

[0122] Furthermore, as shown in Figure 4, the distance between the axis of the conveyor roller 22 and the ribbon cartridge 40 is d1, and the distance between the axis of the printing roller 32 and the ribbon cartridge 40 is d2. The difference between d1 and d2 is in the range of 1cm to 5cm. Since d1 is greater than d2, the value range of d1-d2 is 1cm≤(d1-d2)≤5cm, which can ensure the relative position of the conveyor roller 22 and the printing roller 32. If the distance difference between the conveyor roller 22 and the printing roller 32 to the ribbon cartridge 40 is too large, such as a difference greater than 5cm, the bending angle of the wire tube 2 will be too large during its journey from the conveyor assembly 20a to the printing assembly 30 and then to the outlet 12a, resulting in an unsmooth flow of the wire tube 2. If the distance difference between the conveyor roller 22 and the printing roller 32 to the ribbon cartridge 40 is too small, such as a difference less than 1cm, the contact area between the wire tube 2 and the ribbon sleeve on the printable part 33 will be too large when the wire tube 2 reaches the printing assembly 30, thereby rubbing off the toner on the ribbon sleeve and resulting in poor printing effect of the wire tube 2 by the printable part 33.

[0123] In some embodiments of this application, the shortest connection between the axis of the conveyor roller 22 and the axis of the printing roller 32 is the first connection (not shown in the figure), and the connection between the axis of the conveyor roller 22 and the outlet 12a is the second connection (not shown in the figure). The first connection and the second connection are set at an angle.

[0124] The axis of the conveyor roller 22 is parallel to the axis of the printing roller 32. The shortest connecting line between the axis of the conveyor roller 22 and the axis of the printing roller 32 is perpendicular to both the axis of the conveyor roller 22 and the axis of the printing roller 32. That is, the first connecting line is perpendicular to both the axis of the conveyor roller 22 and the axis of the printing roller 32. The first connecting line and the second connecting line are not parallel, which allows the wire tube 2 to enter the second channel 31 of the printing assembly 30 at an angle relative to the ribbon cartridge 40. This facilitates the formation of a curved tube path 13. As the wire tube 2 moves from the conveyor assembly 20a to the printing assembly 30 and then to the outlet 12a, the wire tube 2 extends in a bent shape, keeping the portion of the wire tube 2 in the wire tube printer 1 in a taut state. This reduces the possibility of the wire tube 2 loosening during its movement in the wire tube printer 1.

[0125] Furthermore, the included angle between the first and second connecting lines is in the range of 10° to 70°, which is beneficial for controlling the relative positional relationship of the conveyor roller 22, the printing roller 32 and the outlet 12a. This not only prevents the bending degree of the tube path 13 of the wire tube 2 from being too large, but also prevents the contact area between the wire tube 2 and the ribbon sleeve at the printing assembly 30 from being too large, which would cause the wire tube 2 to wipe away most of the toner on the ribbon sleeve.

[0126] In some embodiments of this application, as shown in FIG3, the printer 33 has a printing portion 331 facing the second channel 31. The printing portion 331 is configured to contact the wire tube 2. The printing portion 331 is set at an angle to the first connecting line, that is, the first connecting line is not parallel to the printing portion 331. When the wire tube 2 extends from the conveying assembly 20a to the printing assembly 30 until the printing portion 331 contacts the wire tube 2, the contact surface between the wire tube 2 and the printing portion 331 is also set at an angle to the first connecting line. This makes the wire tube 2 enter the second channel 31 of the printing assembly 30 at an incline relative to the ribbon cartridge 40, which is beneficial to forming a curved tube path 13.

[0127] The printing section 331 on the printing part 33 can be a heating resistor on the thermal print head. The multiple heating resistors on the thermal print head are arranged in a straight line, so the printing section 331 extends in a straight line on the printing part 33.

[0128] Please refer to Figures 3-4. In some embodiments of this application, the printing section 331 is located on the side of the axis of the printing roller 32 near the outlet 12a. For example, the conveying component 20a is located on the right side of the printing component 30, and the outlet 12a is located on the left side of the printing component 30. The positions of the conveying component 20a, the printing component 30, and the outlet 12a are staggered to form a bent tube path 13. The printing section 331 is located on the left side of the printing roller 32, which causes the wire tube 2 to bend at the printing roller 32. After the wire tube 2 extends around the circumference of the printing roller 32 and passes through the printing section 331, the wire tube 2 separates from the printing section 331. The wire tube 2 continues to extend from the left side of the printing roller 32 along the tangential direction of the printing roller 32 to the outlet 12a. That is, the wire tube 2 extends obliquely upward from the left side of the printing roller 32.

[0129] The minimum distance between the centerline of the outlet 12a and the axis of the printing roller 32 is less than the distance between the printing section 331 and the axis of the printing roller 32. Specifically, the perpendicular distance between the centerline of the outlet 12a and the axis of the printing roller 32 is the minimum distance between the centerline of the outlet 12a and the axis of the printing roller 32. Therefore, in the perpendicular direction from the centerline of the outlet 12a to the axis of the printing roller 32, the centerline of the outlet 12a is located between the axis of the printing roller 32 and the printing section 331. As a result, when the wire tube 2 extends from the second channel 31 to the outlet 12a, the wire tube 2 needs to extend around the circumference of the printing roller 32 in a direction away from the printing section 331, so that the wire tube 2 can separate from the printed part 33 as soon as possible after contact, thereby reducing the contact area between the wire tube 2 and the printed part 33 and reducing the amount of toner wiped off the ribbon sleeve by the wire tube 2.

[0130] In some embodiments of this application, as shown in Figures 3 and 5, the outlet wall of the tube 12a includes a first sidewall 121 away from the printout 33. After the wire tube 2 separates from the printout 33, it extends toward the outlet 12a. Since the position of the outlet 12a is not on the same straight line as the position of the second channel 31, when the wire tube 2 reaches the outlet 12a, it will contact the first sidewall 121 of the outlet 12a and turn to continue extending in the direction of the centerline of the outlet 12a. The first sidewall 121 is spaced apart from the printout 331. This space can provide displacement space for the wire tube 2 and prevent the wire tube 2 from blocking the first sidewall 121 of the outlet 12a after it comes out of the second channel 31.

[0131] Furthermore, as shown in Figure 3, the distance between the first sidewall 121 and the printing part 331 is d3, and d3 is not less than 1cm. If d3 is too small, the displacement space provided for the wire tube 2 will be too small, and it will also easily cause the wire tube 2 to be blocked at the first sidewall 121 of the outlet 12a after it comes out of the second channel 31.

[0132] Please refer to Figure 5. In some embodiments of this application, the wire marking tube printer 1 further includes a cutting assembly 50. The cutting assembly 50 is disposed on the host 10 and located at the tube outlet 12a. The cutting assembly 50 has a third channel 51 communicating with the tube outlet 12a. The cutting assembly 50 includes a cutting element 52 and a support element 53 disposed opposite to each other. The third channel 51 is located between the cutting element 52 and the support element 53. After the wire marking tube 2 passes through the second channel 31, it can enter the third channel 51 of the cutting assembly 50. The cutting element 52 can move relative to the host 10 to cut the wire marking tube 2 located in the third channel 51. The cutting element 52 can be a cutter, and the support element 53 can provide support for the wire marking tube 2.

[0133] The cutting assembly 50 may also include an elastic element that is telescopically disposed in the third channel 51, and the elastic element and the cutting element 52 are disposed on the same side of the third channel 51. When the wire tube 2 is cut in the third channel 51, the elastic element extends and clamps the wire tube 2 between the elastic element and the support 53. Then the cutting element 52 extends and cuts the wire tube 2.

[0134] In some embodiments, as shown in FIG5, the distance from the position of the second channel 31 to the cutting member 52 is less than the distance from the position of the second channel 31 to the support member 53. It is easy to understand that the support member 53 is located on the side of the third channel 51 away from the second channel 31, and the cutting member 52 is located on the side of the third channel 51 close to the second channel 31. This causes the wire tube 2 to move towards the support member 53 when it extends from the second channel 31 to the outlet 12a.

[0135] The support member 53 has a circular arc shape on its periphery. The circular arc surface on the support member 53 can guide the movement of the wire tube 2, so that the wire tube 2 extends into the third channel 51, thereby preventing the wire tube 2 from being blocked at the cutting member 52.

[0136] Example 2

[0137] As shown in Figures 6 to 8, the wire marking tube printer includes a main unit 10, a tube feeding assembly 20b, and a printing assembly 30. The main unit 10 has a tube feeding groove 11a for the wire marking tube 80 to pass through. The wire marking tube 80 can pass through the tube feeding groove 11a in the direction of extension from the inlet end 111 to the outlet end 112 of the tube feeding groove 11a. The tube feeding assembly 20b is located on the main unit 10 and is configured to drive the wire marking tube 80 to move along the tube feeding groove 11a to realize the passage of the wire marking tube 80. The printing assembly 30 is located on the main unit 10 and is configured to print labels on the wire marking tube 80 to classify the different uses of the wire marking tube 80.

[0138] The wire marking tube printer also includes a first tube blockage detection component 40a and a control component; the first tube blockage detection component 40a is disposed on the host 10 and is configured to detect the movement of the wire marking tube 80; the control component is disposed on the host 10 and is communicatively connected to the tube feeding component 20b and the first tube blockage detection component 40a. The control component is configured to control the tube feeding component 20b to stop operating when the first tube blockage detection component 40a detects that the wire marking tube 80 in the tube feeding groove 11a is blocked. The control component can be a control circuit board.

[0139] Understandably, in this application, the first tube blockage detection component 40a can detect the movement of the wire marking tube 80. When the first tube blockage detection component 40a detects that the wire marking tube 80 in the tube delivery groove 11a is blocked, it can send a blockage signal to the control component in a timely manner. The control component controls the tube delivery component 20b to stop running, thereby allowing the wire marking tube 80 to stop moving in a timely manner. This can prevent the wire marking tube printer from printing on different parts of the wire marking tube 80 as required by the design, thus preventing a large amount of waste of the wire marking tube 80, and can also prevent the wire marking tube printer from being damaged due to tube blockage.

[0140] In some embodiments of this application, the printing assembly 30 includes a printing roller 31a and a print head 32a; the printing roller 31a is located in the tube feed groove 11a and is rotatably connected to the host 10; the print head 32a is disposed opposite to the printing roller 31a, and a first tube feed channel 33a is formed between the print head 32a and the printing roller 31a to allow the wire marking tube 80 to pass through. It is understood that when printing the wire marking tube 80, the wire marking tube 80 is passed through the first tube feed channel 33a and sandwiched between the print head 32a and the printing roller 31a. When the wire marking tube 80 moves along the tube feed direction of the tube feed groove 11a, the printing roller 31a rotates relative to the host 10 (taking the perspective shown in FIG. 7 as an example, the printing roller 31a will rotate clockwise) to feed the tube, while the print head 32a prints the printing layer in the ribbon onto the wire marking tube 80, thereby realizing the label printing of the wire marking tube 80.

[0141] The printing roller 31a is spaced apart from the side of the first tube channel 33a and the sidewall of the tube groove 11a. The sidewall of the tube groove 11a includes a first sidewall 113 facing the printing roller 31a. The printing roller 31a and the first sidewall 113 are arranged sequentially along the tube direction of the tube groove 11a (i.e., the first sidewall 113 is located on the side of the printing roller 31a away from the inlet end 111). A first gap space 51 is formed between the first sidewall 113 and the printing roller 31a. It should be noted that by spaced apart between the printing roller 31a and the sidewall of the tube groove 11a, a rotational gap is provided between the printing roller 31a and the sidewall of the tube groove 11a to allow the printing roller 31a to rotate smoothly. This prevents friction between the printing roller 31a and the sidewall of the tube groove 11a from affecting the rotation of the printing roller 31a.

[0142] In some embodiments, the distance between the printing roller 31a and the sidewall of the tube groove 11a is L1, where 0.1 mm ≤ L1 ≤ 1 mm. When L1 is less than 0.1 mm, the gap between the printing roller 31a and the sidewall of the tube groove 11a is too small, and the printing roller 31a is prone to friction with the sidewall of the tube groove 11a, affecting the rotation of the printing roller 31a. When L1 is greater than 1 mm, the gap between the printing roller 31a and the sidewall of the tube groove 11a is too large, and the printing roller 31a is prone to bringing the wire tube 80 into the first gap space 51 when rotating, causing tube blockage. L1 can be 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 1 mm, or other values.

[0143] In some embodiments, at least a portion of the first tube blockage detection element 40a is disposed in the first gap space 51. The first tube blockage detection element 40a is configured to detect the movement of the wire number tube 80 within the first gap space 51. When the first tube blockage detection element 40a detects that the wire number tube 80 is blocked in the first gap space 51, the control component controls the tube feeding component 20b to stop operating. It is understood that during the tube feeding process, the probability of the tube being carried into the first gap space 51 by the printing roller 31a, resulting in tube blockage, is relatively high. By using the first tube blockage detection element 40a to directly detect the movement of the wire number tube 80 within the first gap space 51, it is possible to better determine whether the wire number tube 80 is blocked in the first gap space 51, thereby improving detection accuracy and reducing the probability of not stopping tube feeding in time when blockage occurs.

[0144] In some embodiments, the first pipe blockage detection element 40a can be a first microswitch sensor. When the wire tube 80 touches the actuating part of the first microswitch sensor, the first microswitch sensor sends a pipe blockage signal to the control component, and the control component controls the pipe feeding component 20b to stop operating. The working principle of the microswitch sensor has been disclosed in related technologies and will not be elaborated here. In other embodiments, the first pipe blockage detection element 40a can also be an infrared detection sensor, a pressure sensor, or other sensors that can detect the movement of the wire tube 80.

[0145] As shown in Figures 9 and 10, the first micro switch sensor includes a first actuation part 41 and a first detection part 42; the first actuation part 41 is rotatably connected to the host 10; it is configured to detect the position of the first actuation part 41 in order to detect the movement of the wire tube 80 in the first gap space 51, and the control component is communicatively connected to the first detection part 42.

[0146] The first actuating part 41 has a first actuating surface 411 located in the first gap space 51 and facing the printing roller 31a. The first actuating surface 411 is configured to contact the wire tube 80 when the wire tube 80 enters the first gap space 51. When the wire tube 80 contacts the first actuating surface 411 and drives the first actuating part 41 to rotate, the first detection part 42 detects that the wire tube 80 is blocked in the first gap space 51, and the control component controls the tube feeding assembly 20b to stop operating. Understandably, when the wire tube 80 moves to the first gap space 51 and contacts the first contact surface 411, as the wire tube 80 continues to move, the first contact part 41 will be pushed by the wire tube 80, causing the position of the first contact part 41 to change. The first detection unit 42 can detect the position of the first contact part 41. When the first detection unit 42 detects that the position of the first contact part 41 has changed, the first detection unit 42 detects that the wire tube 80 is blocked in the first gap space 51 and sends a blockage signal to the control component. The control component controls the tube delivery component 20b to stop operating.

[0147] It should also be noted that the host 10 may be provided with a first mounting hole 12b configured to mount the printing roller 31a. The shaft of the printing roller 31a is mounted in the first mounting hole 12b. The rotation axis of the first actuating part 41 may be parallel to the rotation axis of the printing roller 31a, and the first actuating part 41 may rotate around its rotation axis. The first detection part 42 may be a light sensor. When the position of the first actuating part 41 changes, the detection light detected by the light sensor changes, thereby detecting the change in the position of the first actuating part 41. A position can be formed on the host 10. The first receiving space 13 is located on the side of the first side wall 113 away from the first gap space 51. The first detection part 42 is located in the first receiving space 13 to prevent dust and other dirt from causing false detection by the first detection part 42. The first side wall 113 is provided with a first connecting hole 14 connecting the first receiving space 13 and the first gap space 51. The part of the first actuating part 41 that cooperates with the first detection part 42 is located in the first receiving space 13, and the part of the first actuating part 41 with the first actuating surface 411 extends from the first connecting hole 14 to the first gap space 51.

[0148] In some embodiments, the distance between the portion of the first actuating surface 411 furthest from the first sidewall 113 and the first sidewall 113 along the tube-running direction of the tube groove 11a is L2, where 1 mm ≤ L1 ≤ 20 mm. It is understood that when L2 is less than 1 mm, the length of the portion of the first actuating part 41 extending from the first connecting hole 14 into the first gap space 51 is relatively short. When the wire tube 80 enters the first gap space 51, it is difficult for it to contact the first actuating surface 411, which results in low detection sensitivity of the first tube blockage detection element 40a. When L2 is greater than 20 mm, the first actuating surface 411 easily contacts the printing roller 31a, thereby causing friction with the printing tube and affecting its rotation. It may also be triggered by the printing tube, leading to false detections. L2 can be 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, or other values.

[0149] In some embodiments, the first actuating surface 411 includes a first abutting surface 411a and a second abutting surface 411b. The second abutting surface 411b is located in the first gap space 51 and connected to the first abutting surface 411a. The second abutting surface 411b extends obliquely away from the first abutting surface 411a and away from the print head 32a, so that when the wire tube 80 enters the first gap space 51 and abuts against the second abutting surface 411b, it is easier to push the second abutting surface 411b to rotate away from the print head 32a. This makes it easier for the first actuating part 41 to rotate away from the print head 32a, thereby enabling the first tube blockage detection element 40a to have higher detection sensitivity.

[0150] In some embodiments of this application, as shown in Figures 6, 11, and 12, the tube feeding assembly 20b and the printing assembly 30 are arranged along the tube feeding direction. The tube feeding assembly 20b includes a conveying roller 21a, a floating roller 22a, and a driving component. The conveying roller 21a is located in the tube feeding groove 11a and is rotatably connected to the host 10. The floating roller 22a is arranged opposite to the conveying roller 21a, and a second tube feeding channel 23 is formed between the floating roller 22a and the conveying roller 21a to allow the wire number tube 80 to pass through. The driving component is drively connected to the conveying roller 21a and is configured to drive the conveying roller 21a to rotate. The driving component is communicatively connected to the control component, and the control component is configured to stop the driving component when the first tube blockage detection component 40a detects that the wire number tube 80 in the tube feeding groove 11a is blocked. It is understandable that when printing the wire number tube 80, the wire number tube 80 passes through the inlet end 111, the second tube passage 23, the first tube passage 33a and the outlet end 112 in sequence. The control component controls the drive to drive the conveyor roller 21a to rotate relative to the host 10 (taking the view shown in Figure 11 as an example, the conveyor roller 21a will rotate clockwise) to feed the tube. The rotation axis of the conveyor roller 21a can be parallel to the rotation axis of the printing roller 31a. The conveyor roller 21a can rotate around its rotation axis. The drive can be an electric motor or other electric component.

[0151] The conveyor roller 21a is spaced apart from the side of the tube channel 23 and the sidewall of the tube groove 11a. The sidewall of the tube groove 11a includes a second sidewall 114 facing the conveyor roller 21a. The second sidewall 114 and the conveyor roller 21a are arranged sequentially along the tube direction of the tube groove 11a (i.e., the second sidewall 114 is located on the side of the conveyor roller 21a near the inlet end 111). A second gap space 52 is formed between the second sidewall 114 and the conveyor roller 21a. It should be noted that by spaced apart between the conveyor roller 21a and the sidewall of the tube groove 11a, a rotational gap is provided between the conveyor roller 21a and the sidewall of the tube groove 11a to allow the conveyor roller 21a to rotate smoothly. This prevents friction between the conveyor roller 21a and the sidewall of the tube groove 11a from affecting the rotation of the printing roller 31a.

[0152] In some embodiments, the distance between the conveying roller 21a and the sidewall of the tube trough 11a is L3, where 0.1 mm ≤ L3 ≤ 1 mm. When L3 is less than 0.1 mm, the gap between the conveying roller 21a and the sidewall of the tube trough 11a is too small, and the conveying roller 21a is prone to friction with the sidewall of the tube trough 11a, affecting the rotation of the conveying roller 21a. When L3 is greater than 1 mm, the gap between the conveying roller 21a and the sidewall of the tube trough 11a is too large, and the wire tube 80 is prone to enter the second gap space 52, causing blockage. L2 can be 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 1 mm, or other values.

[0153] In some embodiments, the wire marking tube printer further includes a second tube blockage detection element, at least partially disposed in the second gap space 52. The second tube blockage detection element is configured to detect the movement of the wire marking tube 80 within the second gap space 52. When the second tube blockage detection element detects that the wire marking tube 80 is blocked in the second gap space 52, the control component controls the tube feeding assembly 20b to stop operating. It is understood that during the tube feeding process, the probability of the tube entering the second gap space 52 and causing blockage is relatively high. By using the second tube blockage detection element to directly detect the movement of the wire marking tube 80 within the second gap space 52, it is possible to better determine whether the wire marking tube 80 is blocked in the second gap space 52, thereby improving detection accuracy and reducing the probability of not stopping tube feeding in time when blockage occurs.

[0154] In some embodiments, the second pipe blockage detection element can be a second microswitch sensor. When the wire tube 80 touches the actuating part of the second microswitch sensor, the second microswitch sensor sends a pipe blockage signal to the control component, and the control component controls the pipe feeding assembly 20b to stop operating. In other embodiments, the second pipe blockage detection element can also be an infrared detection sensor, a pressure sensor, or other sensors that can detect the movement of the wire tube 80.

[0155] The second micro switch sensor includes a second actuating part and a second detection part; the second actuating part is rotatably connected to the main unit 10; the second detection part is configured to detect the position of the second actuating part in order to detect the movement of the wire tube 80 in the second gap space 52, and the control component is communicatively connected to the second detection part.

[0156] The second actuating part has a second actuating surface located in the second gap space 52 and facing the conveyor roller 21a. The second actuating surface is configured to contact the wire tube 80 when it enters the second gap space 52. When the wire tube 80 contacts the second actuating surface and drives the second actuating part to rotate, the second detection part detects that the wire tube 80 is blocked in the second gap space 52, and the control component controls the tube feeding assembly 20b to stop operating. It can be understood that when the wire tube 80 moves into the second gap space 52 and contacts the second actuating surface, as the wire tube 80 continues to move, the second actuating part is pushed by the wire tube 80, causing a change in the position of the second actuating part. The second detection part can detect the position of the second actuating part. When the second detection part detects a change in the position of the second actuating part, it detects that the wire tube 80 is blocked in the second gap space 52 and sends a blockage signal to the control component, which then controls the tube feeding assembly 20b to stop operating.

[0157] It should also be noted that, as shown in Figure 12, the host 10 may be provided with a second mounting hole 15 configured to install the conveyor roller 21a, and the shaft of the conveyor roller 21a is installed in the second mounting hole 15; the second detection unit may be a light sensor. When the position of the second touch part changes, the detection light detected by the light sensor changes, thereby detecting the change in the position of the second touch part. The host 10 may be provided with a second receiving space 16 located on the side of the second side wall 114 away from the second gap space 52. The second detection unit is located in the second receiving space 16 to prevent dust and other dirt from causing false detection by the second detection unit. The second side wall 114 is provided with a second connecting hole 17 connecting the second receiving space 16 and the second gap space 52. The part of the second touch part configured to cooperate with the second detection unit is located in the second receiving space 16, and the part of the second touch part with the second touch surface extends from the second connecting hole 17 to the second gap space 52.

[0158] In some embodiments, the distance between the portion of the second contact surface furthest from the second sidewall 114 and the second sidewall 114 along the pipe-running direction of the pipe-running groove 11a is L4, where 1 mm ≤ L4 ≤ 20 mm. It is understood that when L4 is less than 1 mm, the length of the portion of the second contact part extending from the second connecting hole 17 into the second gap space 52 is relatively short. When the wire tube 80 enters the second gap space 52, it is difficult for it to contact the second contact surface, which leads to low detection sensitivity of the second pipe blockage detection element. When L4 is greater than 20 mm, the second contact surface easily contacts the conveyor roller 21a, thereby causing friction with the conveyor roller 21a and affecting its rotation. It may also be touched by the conveyor roller 21a, leading to false detection. L4 can be 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, or other values.

[0159] In some embodiments, the second actuating surface includes a third abutting surface and a fourth abutting surface. The fourth abutting surface is located in the second gap space 52 and is connected to the third abutting surface. The fourth abutting surface extends obliquely away from the third abutting surface and away from the floating roller 22a, so that when the wire tube 80 enters the second gap space 52 and abuts against the fourth abutting surface, it is easier to push the fourth abutting surface to rotate away from the floating roller 22a. This makes it easier for the second actuating part to rotate away from the floating roller 22a, thereby enabling the second tube blockage detection element to have higher detection sensitivity.

[0160] As shown in Figure 13, in some embodiments of this application, the bottom of the tube channel 11a includes a first base plate 18 and a second base plate 19. The wire marking tube printer also includes a tube cutting assembly 60 and a camera detection component 70. The tube cutting assembly 60 is configured to cut the wire marking tube 80. The first base plate 18, the tube cutting assembly 60, and the second base plate 19 are arranged sequentially along the tube direction of the tube channel 11a. The camera detection component 70 is disposed on the host 10. The camera detection component 70 is configured to detect the movement of the wire marking tube 80 at the second base plate 19. The camera detection component 70 is communicatively connected to the control component. The control component is also configured to control the tube feeding assembly 20b to stop operating when the camera detection component 70 detects that the wire marking tube 80 is blocked at the second base plate 19.

[0161] It is understandable that the second base plate 19 is located near the outlet end 112, and the pipe cutting assembly 60 is located between the second base plate 19 and the first base plate 18. When the wire tube 80 passes through the first base plate 18, the pipe cutting assembly 60 and the second base plate 19 in sequence along the pipe running direction, in order to raise the wire tube 80 so that the pipe cutting assembly 60 can cut the wire tube 80, a stepped structure will be formed at the second base plate 19, which makes the wire tube 80 easy to get blocked at the second base plate 19, resulting in pipe blockage. In this embodiment, a camera detection device 70 is set to detect the movement of the wire tube 80 at the second base plate 19. When the camera detection device 70 detects that the wire tube 80 is blocked at the second base plate 19, it can send a blockage signal to the control component in time. The control component controls the pipe feeding assembly 20b to stop running, so that the wire tube 80 can stop running in time.

[0162] The tube cutter may include an anvil 61 and a cutter 62, which are arranged opposite to each other. A tube cutting channel is formed between the anvil 61 and the cutter 62 to allow the wire tube 80 to pass through. The cutter 62 can cut the wire tube 80 passing through the tube cutting channel.

[0163] The camera detection component 70 is disposed on the side wall of the pipe channel 11a and located to the side of the second base plate 19, thereby shortening the distance between the camera detection component 70 and the second base plate 19. This facilitates the camera detection component 70 in detecting the movement of the wire gauge tube 80 at the second base plate 19, improving the detection accuracy of the camera detection component 70. It should be noted that, taking the view shown in Figure 13 as an example, the camera detection component 70 can be disposed only on the upper side wall of the second base plate 19 or on the lower side wall of the second base plate 19, or it can be disposed on both the upper side wall of the second base plate 19 and the lower side wall of the second base plate 19.

[0164] Furthermore, the distance between the camera detection component 70 and the top opening of the pipe channel 11a is less than the distance between the camera detection component 70 and the second base plate 19, so that the camera detection component 70 is set closer to the top opening of the pipe channel 11a, thereby giving the camera detection component 70 a wider imaging range and thus improving the detection accuracy of the camera detection component 70.

[0165] In one embodiment, the camera detection element 70 is a rotatable camera, which allows the camera portion of the camera detection element 70 to rotate at multiple angles, thereby enabling multi-angle detection and giving the camera detection element 70 a wider field of view.

[0166] Example 3

[0167] Please refer to Figures 14-16. This application embodiment provides a printout, including a host 100 and a cover plate 200.

[0168] The main unit 100 is the core component of the printer, containing key components such as the printhead, ink / toner cartridge, and transmission system. Upon receiving a print command, the printhead ejects ink or toner onto the printable material according to a preset pattern or text information, completing the printing task. Simultaneously, the main unit 100 has a printing slot 100a configured for the passage of the printable material. The printing slot 100a has an inlet end 100b and an outlet end 100c, configured for the input and output of the printable material, respectively. Through an internal transmission system (such as rollers or belts), the printable material can be automatically fed in from the inlet end 100b and ejected from the outlet end 100c after printing. The printing slot 100a has a first sidewall 101a and a second sidewall 102a spaced apart.

[0169] The cover plate 200 is rotatably connected to the host 100. Its rotational trajectory has a closed position and a maximum unfolded position. The maximum unfolded position is the limit of the cover plate 200's rotation. After the cover plate 200 rotates to this position, it is limited and cannot continue to rotate. When the cover plate 200 is in the closed position, it covers the host 100 and can effectively protect the key components such as the print head and transmission system in the printing area from damage caused by external factors such as dust and moisture. When the cover plate 200 is in the maximum unfolded position, it is convenient for users to observe the working status of the host 100 and perform maintenance work such as replacing ink cartridges / toner cartridges.

[0170] The first sidewall 101a is located on the side of the second sidewall 102a closer to the cover plate 200. Taking the printer's usage state as a reference, the cover plate 200 and the main unit 100 are rotated to the rear. Therefore, the second sidewall 102a of the printing slot 100a is closer to the user, and the first sidewall 101a of the printing slot 100a is farther away from the user. When the cover plate 200 is in the fully extended position, the projection of the cover plate 200 on the upper surface of the main unit 100 is located on the side of the first sidewall 101a away from the second sidewall 102a. This means that the opening formed between the main unit 100 and the cover plate 200 is relatively large, and there is enough space above the main unit 100. The user can easily see the inside of the printing slot 100a, and there is enough space above the printer to facilitate the user placing the wire tube.

[0171] In one embodiment, referring to Figures 14 and 15, the cover 200 includes an upper cover 210 and a middle cover 220. The upper cover 210 is located outside the main unit 100 and is connected to the main unit 100 by a rotatable connection. The main function of the upper cover 210 is to protect the delicate components inside the printer from dust, paper scraps, and other debris. At the same time, as an exterior component of the printer, it provides a clean and safe appearance.

[0172] The middle cover 220 separates the printing area from other parts, preventing debris and other contaminants from polluting the inside of the printer. Furthermore, the middle cover 220 is located inside the upper cover 210, and its rotation range is smaller than that of the upper cover 210. When the cover plate 200 is in the closed state, the middle cover 220 covers the printing slot 100a, the upper cover 210 covers the upper surface of the printer, and the middle cover 220. The projection of the middle cover 220 onto the upper surface of the host 100 is smaller than the projection of the upper cover 210 onto the upper surface of the host 100. Therefore, in this embodiment, when the cover plate 200 switches from its fully extended position to its closed position, the middle cover 220 can more easily press against the wire marking tubes within the printing slot 100a, ensuring that the wire marking tubes maintain a stable position during printing and preventing them from moving or becoming misaligned, thereby ensuring print quality and accuracy.

[0173] Furthermore, when the cover plate 200 is in its fully extended position, the projections of the upper cover 210 and the middle cover 220 onto the upper surface of the host 100 are both located on the side of the first side wall 101a away from the second side wall 102a. That is, when the cover plate 200 is fully opened, in the vertical direction, the projections of the upper cover 210 and the middle cover 220 onto the upper surface of the host 100 do not obstruct the print slot 100a, allowing the user to quickly insert the wire tube into the print slot 100a. In addition, there is sufficient space for maintenance work, such as cleaning the print head or checking the printing status.

[0174] In one embodiment of this application, the cover plate 200 is rotatably connected to the host 100 via a first rotating shaft. A first torsion spring is sleeved on the first rotating shaft. The first free end of the first torsion spring is connected to the host 100, and the second free end of the first torsion spring is connected to the cover plate 200. Under the action of the elastic force of the first torsion spring, the cover plate 200 has a tendency to move towards the maximum unfolded position.

[0175] When the cover plate 200 is in the fully extended position, the elastic force of the first torsion spring will keep the cover plate 200 stable, preventing it from closing accidentally due to external force or vibration, and ensuring that the cover plate 200 is unlikely to close and cause injury when the user is placing wire pipes or performing maintenance work.

[0176] Please refer to Figures 14 and 15. In one embodiment of this application, when the cover plate 200 is in its fully extended position, viewed from top to bottom, the center of gravity of the cover plate 200 is spaced apart from the host 100, which prevents the cover plate 200 from tipping over or wobbling due to an unstable center of gravity. Especially when it is necessary to keep it open for printing or maintenance for a long time, it can ensure the stability and reliability of the cover plate 200 and prevent damage or safety hazards caused by accidental tipping.

[0177] It should be understood that when the first sidewall 101a is located on the side of the second sidewall 102a away from the user, the projection of the cover 200 in the maximum unfolded position is also located on the side of the first sidewall 101a away from the second sidewall 102a. Thus, even if the cover 200 is accidentally touched, under the action of gravity, the cover 200 has a tendency to fall towards the rear of the host 100, thereby reducing the possibility of the cover 200 suddenly closing in the maximum unfolded position.

[0178] It's also important to understand that printers typically include a ribbon cartridge 500, which contains the ribbon carrying the images, text, and other information to be printed. When the printer is working, the toner or wax on the ribbon is transferred to the marking tubes under the influence of heat, forming clear images or text. The ribbon cartridge 500 is responsible for providing a stable and continuous supply of ribbon during the printing process, ensuring smooth printing.

[0179] The main unit 100 has an upward-facing groove, in which a ribbon box 500 is installed. As a whole component, the ribbon box 500 can be quickly installed and removed when installed in the groove, making ribbon replacement simpler and faster. Users do not need to manually handle the ribbon; they only need to replace the entire ribbon box 500.

[0180] In one embodiment, a pressing member 201 is provided on the inner side of the cover plate 200. When the cover plate 200 is in the closed position, the pressing member 201 presses against the ribbon cartridge 500. The pressing member 201 applies a certain pressure to the ribbon cartridge 500 to prevent it from moving or shaking during the printing process, thus ensuring the stability of the ribbon cartridge 500 in the groove, thereby ensuring the printing quality and preventing damage to the internal components of the printer.

[0181] Furthermore, when the cover plate 200 is in its fully extended position, the projection of the pressing member 201 on the upper surface of the host 100 is located on the side of the first side wall 101a away from the second side wall 102a, that is, in the vertical direction, the projection of the pressing member 201 on the upper surface of the host 100 does not obstruct the printing slot 100a, allowing the user to quickly insert the wire tube into the printing slot 100a. In addition, there is enough space for maintenance work, such as cleaning the print head or checking the printing status.

[0182] Based on the previous embodiment, please refer to Figure 14. The ribbon cartridge 500 is located on the side of the second side wall 102a away from the first side wall 101a. When the second side wall 102a of the printing slot 100a is closer to the user than the first side wall 101a of the printing slot 100a, the ribbon cartridge 500 is also closer to the user. Thus, when the cover 200 is in the fully extended position, the upper surface of the host 100 has enough space to facilitate the user to install or replace the ribbon cartridge 500 at close range.

[0183] In addition, because the ribbon cartridge 500 is closer to the user, the user can see the installation position and method of the ribbon cartridge 500 more clearly, thereby avoiding errors during the installation process and ensuring the normal operation of the printer. It also makes it easier for the user to observe the status of the ribbon cartridge 500, such as the remaining amount of ribbon or whether there is a malfunction, to ensure the continuous and stable operation of the printer.

[0184] In one embodiment of this application, referring to Figures 16 and 17, a first pressing block 300 is provided on the inner side of the cover plate 200. The first pressing block 300 has a first end 301 and a second end 302. The first end 301 is rotatably connected to the cover plate 200, and the second end 302 is configured to abut against the workpiece to be printed when the cover plate 200 is in the closed position, so as to keep it flat and prevent it from moving during the printing process. Through the pressing action of the first pressing block 300, the relative position between the print head and the workpiece to be printed can be kept stable, thereby improving the print quality.

[0185] In this embodiment, when the cover plate 200 is in the closed position, the first end 301 is located on the side of the second end 302 near the inlet end 100b. The user can manually swing the first pressure block 300 so that the first pressure block 300 is in an inclined state, that is, the first end 301 is located on the side of the second end 302 near the inlet end 100b, until the second end 302 presses against the wire tube. The user can then remove their hand and continue to rotate the cover plate 200 until the cover plate 200 is in the closed position.

[0186] Described in the orientation shown in Figure 14, the inlet end 100b is located on the right and the outlet end 100c is located on the left. Correspondingly, the second end 302 is on the left and the first end 301 is on the right. That is, the wire tube moves from the right to the left. Thus, when the second end 302 presses against the wire tube, the friction between the wire tube and the second end 302 will cause the first pressure block 300 to have a clockwise rotation tendency. In this way, as the wire tube continues to move, the friction between the wire tube and the second end 302 is difficult to increase, which can ensure the smoothness of the wire tube passing through the tube.

[0187] Furthermore, when the cover plate 200 is in its fully extended position, the projection of the first pressing block 300 on the upper surface of the host 100 is located on the side of the first side wall 101a away from the second side wall 102a, that is, in the vertical direction, the projection of the first pressing block 300 on the upper surface of the host 100 does not obstruct the printing slot 100a, so that the user can quickly put the wire tube into the printing slot 100a. In addition, there is enough space for maintenance work, such as cleaning the print head or checking the printing status.

[0188] In one embodiment of this application, the first end 301 is rotatably connected to the cover plate 200, so that the first pressing block 300 is flexibly set relative to the cover plate 200. In this way, when dealing with wire tubes of different diameters, the position of the first pressing block 300 relative to the printing groove 100a can be adaptively adjusted, thereby adapting to wire tubes of different specifications within a certain range.

[0189] Furthermore, since the first pressure block 300 is flexibly set relative to the cover plate 200, meaning it has a certain rotation trajectory, if a user accidentally touches the first pressure block 300, since the first pressure block 300 and the cover plate 200 are not relatively fixed, the first pressure block 300 can rotate to avoid being touched by the user, thereby reducing the possibility of the first pressure block 300 breaking.

[0190] In the above embodiments, the pressure of the first pressure block 300 on the wire tube is mainly achieved by its own weight. In order to further improve the pressure of the first pressure block 300 on the wire tube, in one embodiment of this application, as shown in Figures 17 and 18, the first end 301 is rotatably connected to the cover plate 200 through the second rotating shaft 303. A second torsion spring 304 is sleeved on the second rotating shaft 303. The first free end of the second torsion spring 304 is connected to the cover plate 200, and the second free end of the second torsion spring 304 is connected to the first pressure block 300. Under the action of the elastic force of the second torsion spring 304, the first end 301 has a tendency to move away from the cover plate 200, that is, under the action of the elastic force, the first end 301 will move closer to the printing groove 100a.

[0191] That is, under the elastic force of the second torsion spring 304, the first pressure block 300 is driven to press against the wire marking tube. Under the elastic force of the second torsion spring 304 and combined with the weight of the first pressure block 300, the wire marking tube can be pressed more stably, ensuring the accuracy of the wire marking tube printing.

[0192] Since the second end 302 of the first pressure block 300 presses against the wire tube when the cover plate 200 is closed, friction will be generated between the first pressure block 300 and the wire tube. The further friction may affect the smoothness of the wire tube.

[0193] Therefore, in one embodiment of this application, please refer to Figures 17 and 18. The first pressing block 300 includes a first body 310 and a first rolling part 320. The two ends of the first body 310 are respectively formed as a first end 301 and a second end 302. The first rolling part 320 is rotatably connected to the second end 302. When the cover plate 200 is in the closed state, the first rolling part 320 is configured to abut against the workpiece to be printed.

[0194] The axis of the first rolling part 320 is parallel to the axis of the shaft connecting the first end 301 and the cover plate 200. Therefore, the contact between the first rolling part 320 and the wire tube is rolling contact. Rolling contact means that there is less rolling friction. Therefore, the wear on the wire tube can be reduced by the first rolling part 320, and the smoothness of the wire tube can also be improved.

[0195] Furthermore, the first rolling part 320 is made of an elastic material, such as rubber, silicone, or polyurethane. By using an elastic material for the first rolling part 320, it can better adapt to the unevenness of the wire tube surface and ensure that the pressure is evenly distributed across the entire contact surface through slight deformation, thereby reducing printing quality problems caused by excessive local pressure.

[0196] In one embodiment, please continue to refer to Figures 14 and 15. The printer also includes a second pressing block 400a, which is disposed on the inner side of the cover plate 200 and spaced apart from the first pressing block 300. When the cover plate 200 is in the closed position, the second pressing block 400a is configured to press against the workpiece to be printed.

[0197] When the cover plate 200 is in the closed state, the first pressing block 300 presses against the wire tube. Under the action of the pressing force, the position in contact with the first pressing block 300 will sink, and the adjacent position may lift up. Therefore, by setting the second pressing block 400a, it can press against the wire tube at intervals with the first pressing block 300 when the cover plate 200 is in the closed state, which plays an auxiliary pressing role and ensures that the wire tube moves in the printing slot 100a according to the preset trajectory.

[0198] It should be understood that, in this embodiment, the second pressure block 400a is located on the side of the first pressure block 300 near the inlet end 100b, which can ensure the smoothness of the tube inlet. In this embodiment, when the cover plate 200 is in the maximum unfolded position, the projection of the second pressure block 400a on the upper surface of the host 100 is located on the side of the first side wall 101a away from the second side wall 102a. That is, in the vertical direction, the projection of the second pressure block 400a on the upper surface of the host 100 does not obstruct the printing slot 100a, so that the user can quickly put the wire tube into the printing slot 100a. In addition, there is enough space for maintenance work, such as cleaning the print head or checking the printing status.

[0199] Furthermore, please refer to Figures 17 and 18. The second pressing block 400a includes a second body 410 and a second rolling part 420. The second rolling part 420 is rotatably connected to the second body 410. When the cover plate 200 is in the closed state, the second rolling part 420 is configured to press against the workpiece to be printed.

[0200] The axis of the second rolling part 420 is parallel to the axis of the shaft connecting the first end 301 and the cover plate 200. That is, the axis of the second rolling part 420 is parallel to the axis of the first rolling part 320. Therefore, the contact between the second rolling part 420 and the wire tube is also a rolling contact. Rolling contact means that there is less rolling friction. Therefore, the wear on the wire tube can be reduced by the second rolling part 420, and the smoothness of the wire tube can also be improved.

[0201] The material of the second rolling part 420 can be the same as that of the first rolling part 320, namely, an elastic material, such as rubber, silicone, or polyurethane. This material can better adapt to the uneven surface of the wire tube and ensure that the pressure is evenly distributed across the entire contact surface through slight deformation, thereby reducing printing quality problems caused by excessive local pressure.

[0202] In one embodiment of this application, please refer to Figures 14 and 15. A third pressing block 600 is provided on the inner side of the cover plate 200. The third pressing block 600 is connected to the cover plate 200. When the cover plate 200 is in the closed position, the third pressing block 600 is configured to press against the printable part near the outlet end 100c.

[0203] When the cover plate 200 is closed, the third pressure block 600 can directly press against the workpiece to be printed near the outlet end 100c, thereby effectively fixing the workpiece to be printed and preventing it from moving or shifting during the printing process. This ensures the accuracy and quality of printing and reduces the probability of printing errors or defects caused by changes in the position of the workpiece to be printed.

[0204] Since the third pressure block 600 and the first pressure block 300 are spaced apart, the third pressure block 600 can also press down the wire tube, reducing the probability of the wire tube lifting up, and further improving the smoothness of the wire tube running in the printing slot 100a.

[0205] Example 4

[0206] Please refer to Figures 19-21. This application embodiment provides a printout, including a host 100, a transmission component 200a, and a printing component 300a.

[0207] The main unit 100 is the core component of the printer, containing key components such as the printhead, ink / toner cartridges, and transmission system. The main unit forms the main structure of the printer, supporting all other components. It provides a stable platform, ensuring the stability and accuracy of each component during printing. The main unit 100 has a printing slot 100a configured for the passage of the printable material. The printing slot 100a has an inlet end 100b and an outlet end 100c, configured for the input and output of the printable material, respectively. Through an internal transmission system (such as rollers, belts, etc.), the printable material can be automatically fed in from the inlet end 100b and ejected from the outlet end 100c after printing.

[0208] The conveying component 200a is mounted on the host 100. The conveying component 200a includes a conveying rubber roller 210 and a floating rubber roller 220. A conveying channel 2000a is formed between the conveying rubber roller 210 and the floating rubber roller 220. The conveying channel 2000a extends along the first direction XX. The conveying rubber roller 210 and the floating rubber roller 220 drive the wire tube to be conveyed along the first direction XX.

[0209] Please refer to Figure 22. The printing component 300a is also mounted on the host 100. The printing component 300a includes a printing roller 310 and a printable part 320. A printing channel 3000a is formed between the printing roller 310 and the printable part 320. The printing channel 3000a extends along the second direction YY. The printing roller 310 and the printable part 320 drive the wire tube to be conveyed along the second direction YY. When a printing command is received, the printable part 320 will spray ink or toner onto the printable part 320 according to the preset pattern or text information to complete the printing task.

[0210] Through the coordinated operation of the conveying component 200a and the printing component 300a, the wire marking tube comes into contact with the conveying roller 210, the floating roller 220, the printing roller 310 and the printed part 320 when passing through the conveying channel 2000a and the printing channel 3000a, thus realizing the continuous conveying and efficient printing of the part to be printed 320.

[0211] In this embodiment, the inner wall of the conveying channel 2000a and the inner wall of the printing channel 3000a form part of the inner wall of the printing groove 100a. The side of the printed part 320 adjacent to the printing channel 3000a faces the conveying channel 2000a and forms a printing surface configured to contact the ribbon.

[0212] The main function of the ribbon is to transfer toner from the ribbon to a medium (such as paper or plastic) under heat, thereby producing a durable and clear printing effect. In the heat transfer process, the ribbon acts as a medium between the ink and resin. Through the heating and pressure of the print head 323, the ink melts and is transferred to the workpiece 320 to form the desired image, text, or barcode.

[0213] The ribbon can be a resin ribbon, a wax-resin mixture ribbon, a wax-based ribbon, or a ribbon made of other materials in the existing technology. These ribbons are prone to breakage when subjected to prolonged or forceful abrasion, which affects printing.

[0214] Generally, the conveyor assembly 200a is closer to the inlet end 100b than the printing assembly 300a. That is, the wire tube moves from the conveyor assembly 200a to the printing assembly 300a. When the first direction XX and the second direction YY are set at an angle, the wire tube moving along the first direction XX will move along the second direction YY when it enters the printing channel 3000a, that is, it changes direction. In this way, the contact area between the wire tube and the ribbon can be reduced. The pressure between the ribbon that is not in contact with the wire tube and the printing surface is relatively reduced, that is, the friction is also relatively reduced. This makes it difficult for the ribbon to rub against the printed part 320, which can protect the ribbon to a certain extent and reduce the probability of ribbon breakage.

[0215] In this embodiment, the printing surface faces the conveying channel 2000a. As a result, the opening of the printing channel 3000a near the conveying channel 2000a is larger, which reduces the risk of the wire tube getting stuck or damaged during the feeding process. This makes it easier for the wire tube to enter the printing channel 3000a, improving the smoothness and reliability of the printing operation.

[0216] It should be understood that the first direction XX and the second direction YY are both directions within a plane, which can be horizontal directions. Taking the printer's usage state as a reference, the printer has a front side close to the user and a rear side opposite to the front side. Therefore, the first direction XX can be a direction that forms an angle with the front and rear directions. In this embodiment of the application, the first direction XX is not restricted.

[0217] In one embodiment of this application, please refer to Figures 21 and 22. The outer diameter of the conveying roller 210 is smaller than the outer diameter of the printing roller 310. This makes it easier to make the extension direction of the conveying channel 2000a and the extension direction of the printing channel 3000a form an angle.

[0218] In addition, because the outer diameter of the conveyor roller 210 is small, it occupies relatively little space, which makes the internal structure of the printer more compact and conducive to the miniaturization and lightweight design of the printer.

[0219] In one embodiment of this application, please refer to Figures 21-23. The conveying roller 210 and the printing roller 310 are located on the same side of the printing groove 100a. The conveying roller 210 has a first projection on the first plane, and the printing roller 310 has a second projection on the first plane. Both the first projection and the second projection are tangent to the first straight line. The first straight line and the first projection have a first intersection point M, and the first straight line and the second projection have a second intersection point N. The first plane is perpendicular to the axis of the conveying roller 210 and the axis of the printing roller 310, and both the first intersection point M and the second intersection point N are located near the printing groove 100a.

[0220] Generally, the host 100 has a front end facing the user and a rear end opposite to the front end. That is, the conveying roller 210 and the printing roller 310 can be located on the front side of the printing tank 100a or on the rear side of the printing tank 100a. There is no limitation on this. In this embodiment, the conveying roller 210 and the printing roller 310 can be located on the front side of the printing tank 100a for illustrative purposes.

[0221] Since the first straight line is the common tangent of the first projection and the second projection, and the line number tube is also in contact with the conveying roller 210 and the printing roller 310, the first straight line is parallel to the line number tube located between the printing channel 3000a and the conveying channel 2000a.

[0222] Please refer to Figure 23. Along the front-back direction, the distance between the first intersection point M and the second intersection point N is h. The range of h is 1cm to 5cm, which can be 1cm, 3cm, 5cm or any two of the above values. Therefore, by keeping h within the above range, not only can the contact area between the wire tube and the ribbon be appropriate, and the friction between the two be appropriate, thus reducing the friction on the ribbon to a certain extent, but it can also ensure that the bending angle of the wire tube within the printing channel 3000a is appropriate, thereby ensuring the smoothness of the wire tube's movement in the printing slot 100a.

[0223] Furthermore, please refer back to Figure 22. The printing surface and the first straight line are set at a preset angle, α, which is in the range of 10° to 70°. It can be 10°, 20°, 30°, 50°, 70°, or any two of the above values. By keeping α within the above range, it is possible to ensure that the contact area between the wire tube and the ribbon is appropriate, and that the friction between the two is appropriate. This can reduce the probability of ribbon breakage caused by the ribbon rubbing against the printed part 320. At the same time, it can also ensure that the bending angle of the wire tube in the printing channel 3000a is appropriate, thereby ensuring the smooth movement of the wire tube in the printing slot 100a.

[0224] Furthermore, in one embodiment of this application, the floating roller 220 is movably connected to the host 100 to adjust the horizontal distance between the conveying roller 210 and the floating roller 220, and the printed part 320 is movably connected to the host 100 to adjust the horizontal distance between the printing roller 310 and the printed part 320.

[0225] By adjusting the horizontal distance between the floating rubber roller 220 and the conveying rubber roller 210, as well as the horizontal distance between the printing rubber roller 310 and the printed part 320, the printer can adapt to wire tubes of different diameters within a certain range. It can also clamp the wire tubes to ensure that they move along a preset trajectory. Furthermore, it is convenient to remove wire tubes that have only been partially printed.

[0226] The movable connection method can use an eccentric wheel as an adjustment element. By rotating the eccentric wheel, the horizontal distance between the floating roller 220 and the conveying roller 210, as well as the horizontal distance between the printing roller 310 and the printed part 320, can be changed. Alternatively, the movement of the floating roller 220 and the printed part 320 can be driven by a pneumatic or hydraulic system to adjust the horizontal distance. Or, a transmission component, such as a gear or drive shaft, can be used to cooperate with the cover plate of the printing slot 100a. When the cover plate is closed on the host 100, the floating roller 220 is close to the conveying roller 210, and the printed part 320 is close to the printing roller 310. When the cover plate is open relative to the host 100, the floating roller 220 is away from the conveying roller 210, and the printed part 320 is away from the printing roller 310.

[0227] It is understandable that in some embodiments, the conveying roller 210 and the printing roller 310 may also be movable relative to the host 100, thereby adjusting the size of the conveying channel 2000a and the printing channel 3000a accordingly.

[0228] The activity connection method can be set according to the actual situation, which will not be explained in detail here.

[0229] In one embodiment of this application, referring back to FIG21 in conjunction with FIG24 and FIG25, the printable part 320 has a first protrusion 321 protruding from the printable surface. The first protrusion 321 is configured to press against the ribbon. The design of the first protrusion 321 is such that the ribbon does not directly contact the entire plane of the printable surface during the printing process, but a portion of the ribbon can contact the first protrusion 321. Thus, the ribbon adjacent to the first protrusion 321 is difficult to contact the printable surface. This reduces the actual contact area between the ribbon and the printable surface, thereby reducing frictional resistance. Reduced frictional resistance helps to reduce ribbon wear, extend its service life, and reduce energy consumption during the printing process.

[0230] Furthermore, in one embodiment, please continue to refer to FIG21, the first boss 321 is disposed at one end of the printing channel 3000a adjacent to the conveying channel 2000a.

[0231] Since the printing surface faces the conveyor channel 2000a, the opening on the side of the printing channel 3000a close to the conveyor channel 2000a is larger. Therefore, there is enough space at the end of the printing channel 3000a adjacent to the conveyor channel 2000a to accommodate the first boss 321, and the protruding first boss 321 will not contact the wire tube, ensuring the smoothness of the wire tube.

[0232] The first boss 321 and the printed part 320 can be integrally formed to increase the overall structural stability, or the first boss 321 and the printed part 320 can be connected by bolts or screws. The specific configuration can be determined according to the actual situation, and no restrictions are imposed here.

[0233] In another embodiment of this application, please continue to refer to Figure 22. The side of the first boss 321 facing away from the printed part 320 is a protruding arc-shaped surface. The arc-shaped surface design reduces the contact area between the carbon ribbon and the first boss 321, thereby reducing friction and wear and extending the service life of the carbon ribbon.

[0234] In addition, since the first protrusion 321 is an arc-shaped surface that contacts the ribbon, it can ensure the smooth movement of the ribbon, thereby ensuring that the material can be stably thermally transferred to the surface of the wire tube and ensuring printing quality.

[0235] When printing on the ribbon vial, it also needs to be moved so that pattern markings can be formed on the surface of the ribbon vial. That is, the ribbon has an inlet end and an outlet end within the printing channel 3000a. Therefore, in one embodiment of this application, please continue to refer to Figure 25. In order to ensure the smooth movement of the ribbon vial, the first protrusion 321 has a guide surface 321a. The guide surface 321a is set facing the inlet end, and the distance between the guide surface 321a and the printing surface gradually increases from the inlet end to the outlet end.

[0236] Thus, the design of the guide surface 321a allows the ribbon to transition smoothly as it moves from the inlet end to the outlet end. The gradually increasing distance between the guide surface 321a and the printing surface ensures that the ribbon will not wrinkle or shift due to sudden changes in direction or excessive pressure within the printing channel 3000a, thereby guaranteeing print quality.

[0237] Furthermore, as the ribbon moves from the feed end to the output end, the distance between the guide surface 321a and the printing surface gradually increases. This helps to reduce the tension of the ribbon during the printing process. Reducing tension can reduce the risk of ribbon wear and breakage, and extend the service life of the ribbon.

[0238] The guide surface 321a can be an outwardly protruding arc surface or an inclined surface. In order to further reduce the friction between the first boss 321 and the carbon ribbon, the guide surface 321a can smoothly transition with other surfaces on the first boss 321.

[0239] In one embodiment of this application, please refer to Figures 24 and 25. The printout 320 includes a print base 322 and a print head 323. The print base 322 is disposed on the printer, and the print head 323 protrudes from the side of the print base 322 facing the print channel 3000a. The side of the print head 323 away from the print base 322 forms a printing surface configured to contact the ribbon.

[0240] The print head 322 is a support structure for the print head 323. It is installed inside the printer and provides a stable foundation, allowing the print head 323 to be precisely positioned on one side of the print channel 3000a.

[0241] The printhead 323 is a key component for performing the printing operation. It transfers images or text onto the printable part 320 by contacting the ribbon. It is important to understand that the printhead 323 is generally a TPH (Thermal Print Head), which has relatively sharp edges. The first boss 321 protrudes at a height greater than that of the printhead 323, which effectively prevents the sharp edge of the TPH-heated printhead 323 from directly contacting the ribbon. This ensures that the ribbon can pass smoothly during the printing process without being cut by the sharp edge of the TPH-heated printhead 323, thereby improving the continuity and stability of the printing.

[0242] Furthermore, the printing surface is provided with heated printing lines 324, which are configured to contact the ribbon. The heated printing lines 324 are a row of heating elements in the thermal printhead 323, which are usually composed of heating resistors with the same resistance and arranged closely. Under normal circumstances, they are configured to generate high temperature through current, thereby initiating a chemical reaction on the dielectric coating and showing color. In this embodiment, the heated printing lines 324 need to contact the ribbon to achieve heating and transfer of the ribbon.

[0243] In some embodiments, the difference between the protrusion height of the first boss 321 and the protrusion height of the print head 323 is d1, and d1 is in the range of 0.5mm-2mm. d1 can be 0.5mm, 1mm, 2mm or any two of the above values. By keeping d1 within the above range, the difference between the protrusion height of the first boss 321 and the protrusion height of the print head 323 is appropriate. This ensures that the ribbon is not easily cut by the print head 323 and that the inclined ribbon can contact the heated printing line 324, thus guaranteeing the printing effect.

[0244] Please refer to Figures 24 and 25. In another embodiment of this application, the print head 320 further includes a second boss 325. The second boss 325 protrudes from the side of the print head 322 facing the print channel 3000a. The second boss 325 and the first boss 321 are distributed at intervals on both sides of the print head 323 along the extension direction of the print channel 3000a. The protrusion height of the second boss 325 is less than the protrusion height of the print head 323.

[0245] The second protrusion 325 can also support the ribbon, reducing the probability of the printhead 323 cutting the ribbon. Since the protrusion height of the second protrusion 325 is less than that of the printhead 323, it ensures that the ribbon can fit tightly against the printhead 323 during printing, avoiding damage to the ribbon due to excessive pressure. On the other hand, the support of the ribbon by the second protrusion 325 can further ensure the stability and safety of the ribbon in the printing channel 3000a, thus further guaranteeing the printing effect.

[0246] Based on the previous implementation, please continue to refer to Figures 24 and 25. The side of the second boss 325 facing away from the printed part 320 is a protruding arc-shaped surface. The arc-shaped surface design makes the contact between the second boss 325 and the ribbon softer, reducing wear caused by direct contact. The arc-shaped surface can disperse the pressure of the ribbon when it passes through, avoid excessive local wear, and help extend the service life of the ribbon.

[0247] It is important to understand that when the first protrusion 321 presses against the ribbon, causing the ribbon to tilt relative to the printing surface, if the difference between the protrusion height of the second protrusion 325 and the protrusion height of the printhead 323 is too large, the second protrusion 325 may have difficulty supporting the ribbon. Therefore, in this application, the difference between the protrusion height of the second protrusion 325 and the protrusion height of the printhead 323 is d2. The value of d2 is in the range of 0.5mm-2mm, and can be 0.5mm, 1mm, 2mm, or any two of the above values. By keeping d2 within the above range, the difference between the protrusion height of the second protrusion 325 and the protrusion height of the printhead 323 can be appropriate, which can both ensure that the ribbon is not easily cut by the printhead 323 and allow the tilted ribbon to contact the second protrusion 325, thus ensuring the printing effect of the ribbon.

[0248] In one embodiment of this application, please refer back to Figures 19 and 20. The printer also includes a ribbon cartridge 400, which is disposed on the host 100. The main function of the ribbon cartridge 400 is to contain and protect the ribbon, ensuring that the ribbon can be supplied smoothly and continuously to the print head 323 during the printing process.

[0249] The ribbon cartridge 400 forms a placement slot 400a with an opening facing the printing channel 3000a, which allows the ribbon to enter the printing area directly and quickly.

[0250] The printed part 320 is at least partially located in the placement slot 400a, that is, the printed part 320 can be partially located in the placement slot 400a or it can be completely located in the placement slot 400a. In this way, the printed part 320 does not occupy additional space in the host 100, making the entire host 100 structure compact and miniaturized.

[0251] Example 5

[0252] Referring to Figures 26 and 27, a printer provided in one embodiment of this application includes a host 10 and a cleaning component 20c. The host 10 has a transmission channel 11b and a printing component 12c. The transmission channel 11b is configured to transmit a printable document 2, and the printing component 12c is configured to print the printable document 2 transmitted through the transmission channel 11b. The cleaning component 20c is disposed within the transmission channel 11b and located upstream of the printing component 12c to clean the printable document 2 before it is transmitted to the printing component 12c.

[0253] The main unit 10 includes a housing, the shape of which is not limited. The housing provides a mounting base and housing space for other mechanical and electrical components of the printer 1.

[0254] The form of the transmission channel 11b can be flexibly selected according to requirements to ensure that the printable part 2 can enter and exit the transmission channel 11b. For example, the transmission channel 11b has an inlet and an outlet at each end, while the middle section is closed. The inlet allows the printable part 2 to enter the transmission channel 11b, and the outlet allows the printable part 2 to exit the transmission channel 11b. Alternatively, the middle section of the transmission channel 11b may have an opening, through which the printable part 2 can enter the transmission channel 11b.

[0255] The structure of the printing assembly 12c is determined according to the type of the workpiece 2 to be printed. For example, when the workpiece 2 to be printed is a wire marking tube, the printing assembly 12c includes a print head and a ribbon. During printing, the ribbon is located between the print head and the workpiece 2 to be printed, and the print head presses the ribbon against the surface of the workpiece 2 to achieve printing. The wire marking tube is also called a sleeve or wire marking sleeve. The printer 1 prints wire markings on the sleeve, which are configured as wiring identifiers.

[0256] The cleaning component 20c is partially or entirely located within the transport channel 11b. Optionally, the cleaning component 20c includes a component configured for cleaning, which is fixed to the host 10 by means of adhesive, snap-fit, or other methods; or, the cleaning component 20c includes a first component configured for cleaning and a second component configured for mounting, with the first component mounted on the host 10 via the second component. The first component cleans contaminants on the surface of the printable 2 using methods including rolling friction and sliding friction.

[0257] Based on the above embodiments, before the printable part 2 is transferred to the printing component 12c, the cleaning component 20c can clean the printable part 2, thereby reducing the risk of contaminants on the printable part 2 affecting the printing effect and improving the printing effect.

[0258] Referring to Figures 28 and 29, in some embodiments, the transmission channel 11b has a first opening 111, which exposes at least a portion of the bottom wall of the transmission channel 11b, that is, the first opening 111 exposes a portion or the entire bottom wall of the transmission channel 11b.

[0259] Referring to Figures 28 and 30, the cleaning assembly 20c includes a cleaning element 21, which is disposed within the transport channel 11b corresponding to the first opening 111, meaning that the cleaning element 21 can enter the transport channel 11b through the first opening 111. The cleaning element 21 is provided with a second opening 211 configured to allow the printable part 2 to enter the cleaning element 21. In this way, the printable part 2 can enter the cleaning element 21 conveniently and quickly, thereby reducing the preparation time before printing and improving printing efficiency.

[0260] In some embodiments, the second opening 211 faces away from the bottom wall of the transmission channel 11b. In this way, the second opening 211 can be partially or completely exposed through the first opening 111, making it easier to place the printable part 2 into the cleaning part 21.

[0261] In some embodiments, the cleaning component 21 is provided with a placement hole 212 communicating with the second opening 211, through which the printable part 2 can enter the placement hole 212. Based on this, after the printable part 2 enters the placement hole 212, during the transmission process of the printable part 2, friction is generated between the surface of the printable part 2 and the hole wall of the placement hole 212, thereby wiping away contaminants on the surface of the printable part 2 and achieving a cleaning effect.

[0262] In other embodiments, the cleaning member 21 is provided with a placement hole 212 spaced apart from the second opening 211. The cleaning member 21 is elastic and can deform to allow the workpiece 2 to be printed to enter the placement hole 212 through the second opening 211. Therefore, after the workpiece 2 enters the placement hole 212, its surface is surrounded by the hole wall of the placement hole 212, increasing the contact area between the surface of the workpiece 2 and the hole wall of the placement hole 212, thereby improving the cleaning effect.

[0263] In some embodiments, the inner diameter of the placement hole 212 is greater than 0 and less than or equal to 3 mm. For example, the inner diameter of the placement hole 212 is 0.1 mm, 1 mm, or 2.5 mm. Based on this, the placement hole 212 can accommodate many common types of parts to be printed 2.

[0264] Optionally, the shape of the placement hole 212 is circular, or the shape of the placement hole 212 is polygonal, such as triangular, quadrilateral, pentagonal, or hexagonal. When the shape of the placement hole 212 is non-circular, the inner diameter of the placement hole 212 refers to its equivalent inner diameter.

[0265] It should be noted that when the diameter of the printable part 2 is larger than the inner diameter of the placement hole 212, the printable part 2 and the cleaning part 21 are in full contact, and the cleaning part 21 can achieve a good cleaning effect on the printable part 2. However, when the diameter of the printable part 2 is smaller than the inner diameter of the placement hole 212, the printable part 2 will still be in contact with the cleaning part 21 under the action of its own gravity and the pulling force during the transmission process, thereby achieving a cleaning effect.

[0266] Referring to Figures 30 and 31, in some embodiments, the cleaning component 21 includes a plurality of cleaning components 213 arranged around a virtual axis L, which is parallel to the central axis of the printable part 2 housed within the cleaning component 21. A second opening 211 is formed between two adjacent cleaning components 213. The virtual axis L is a reference line introduced for ease of understanding. The virtual axis L coincides with or is spaced apart from the central axis of the printable part 2 housed within the cleaning component 21, allowing the plurality of cleaning components 213 to be evenly arranged along the circumference of the printable part 2, thereby uniformly cleaning the circumference and improving the cleaning effect.

[0267] For example, the cross-sectional shape of the cleaning component 213 perpendicular to the virtual axis L is triangular or fan-shaped. Multiple cleaning components 213 are evenly arranged around the virtual axis L, and the cross-sections of the multiple cleaning components 213 perpendicular to the virtual axis L are combined to form a polygon or circle. In this way, the uniformity of the distribution of the multiple cleaning components 213 can be improved, thereby improving the cleaning effect.

[0268] In some embodiments, when the printable part 2 is housed within the cleaning part 21, at least one cleaning component 213 is compressed, causing the end of the cleaning component 213 that abuts against the printable part 2 to bend in the transport direction of the printable part 2. This allows the cleaning component 213 to make full contact with the printable part 2, resulting in better cleaning. Furthermore, the cleaning component 213 is less likely to cause wear to the printable part 2. Moreover, the cleaning component 213 has a larger cleaning range along the transport direction, extending the cleaning path.

[0269] Optionally, the cleaning part 213 is made of sponge, which provides a good cleaning effect while minimizing wear on the printed part 2.

[0270] In one exemplary embodiment, the multiple cleaning components 213 are all made of sponge, and the cross-sectional shape of each cleaning component 213 perpendicular to the virtual axis L is fan-shaped and the same size. The cross-sections of the multiple cleaning components 213 perpendicular to the virtual axis L are combined to form a circle. In this way, the multiple cleaning components 213 can clean the printable 2 uniformly at the same time, improving the cleaning effect.

[0271] Referring again to Figures 30 and 31, in some embodiments, the cleaning component 21 further includes a structural reinforcement layer 214, such as non-woven fabric. The structural reinforcement layer 214 is attached to the side of the plurality of cleaning components 213 facing away from the printing assembly 12c, thereby improving the structural strength of the side of the cleaning component 21 facing away from the printing assembly 12c, so that the cleaning component 21 can better maintain its initial shape after cleaning, thereby ensuring a continuous and stable cleaning effect.

[0272] In some embodiments, multiple cleaning components 213 are integrally formed, which makes it easier to install and fix the cleaning components 21.

[0273] For example, multiple cleaning components 213 are formed by cutting a single piece of cylindrical sponge. On a cross-section perpendicular to the virtual axis L, the notches formed by the cut extend radially outward from the center. This results in cleaning components 21 that provide more uniform cleaning and are easier to install and secure.

[0274] In some embodiments, the cleaning component 21 is detachably mounted on the main unit 10. Thus, when the cleaning component 21 is severely worn, it can be removed and replaced with a new one, thereby ensuring a good cleaning effect.

[0275] Referring again to Figures 30 and 31, in some embodiments, the cleaning assembly 20c further includes a mounting base 22b mounted on the host 10. The mounting base 22b has a receiving groove 221, in which the cleaning component 21 is disposed. Thus, by placing the cleaning component 21 in the receiving groove 221 of the mounting base 22b and mounting the mounting base 22b on the host 10, the installation of the cleaning component 21 is more secure, enabling the cleaning component 21 to stably and effectively clean the printed material 2 during printer 1 operation.

[0276] Optionally, the mounting base 22b can be made of plastic or metal. For example, the mounting base 22b may be made of the same material as the housing of the main unit 10. This simplifies the overall manufacturing process of the printer 1.

[0277] In an exemplary embodiment, the mounting base 22b includes a bottom wall and multiple side walls. The side walls surround the bottom wall and enclose it to form a receiving groove 221. An inlet for the cleaning component 21 to enter the receiving groove 221 is provided on one side of the mounting base 22b opposite to the bottom wall. Two opposing side walls are respectively provided with an inlet and an outlet. After the cleaning component 21 is placed into the receiving groove 221, the printable component 2 can pass through the inlet, the cleaning component 21, and the outlet in sequence. This ensures the smooth passage of the printable component 2, while the side walls of the mounting base 22b with the inlet and outlet can limit the cleaning component 21 in the transport direction of the printable component 2, preventing the cleaning component 21 from shifting position during transport.

[0278] In some embodiments, the mounting base 22b is detachably mounted on the host 10. This allows for flexible replacement of the cleaning component 21 and enables the mounting base 22b to be removed and cleaned. It also allows for cleaning of parts of the host 10 that are covered by the mounting base 22b, thereby preventing clean printable materials 2 from being contaminated by contaminants remaining on the mounting base 22b.

[0279] Referring to Figures 32 and 33, in some embodiments, the host 10 is provided with a mounting slot 13, the mounting slot 13 having a first sidewall 131 and a second sidewall 132 that are opposite to each other along a first direction X.

[0280] Referring further to Figures 30 and 31, the mounting base 22b is provided with a resilient snap-fit ​​member 222 on the side facing the first sidewall 131 and / or the second sidewall 132. The mounting base 22b is resiliently snapped into the mounting groove 13 via the resilient snap-fit ​​member 222. Based on this, the disassembly and installation of the mounting base 22b are more convenient and quick, thereby making the disassembly and installation of the cleaning component 21 more convenient and quick.

[0281] In an exemplary embodiment, the mounting base 22b is provided with a first elastic snap-fit ​​member 2221 on the side facing the first sidewall 131, and the mounting base 22b is elastically snapped into the mounting groove 13 through the first elastic snap-fit ​​member 2221.

[0282] In another exemplary embodiment, the mounting base 22b is provided with a second elastic snap-fit ​​member 2222 on the side facing the second sidewall 132, and the mounting base 22b is elastically snapped into the mounting groove 13 through the second elastic snap-fit ​​member 2222.

[0283] In another exemplary embodiment, the mounting base 22b is provided with a first elastic snap-fit ​​member 2221 on the side facing the first sidewall 131, and a second elastic snap-fit ​​member 2222 on the side facing the second sidewall 132. The mounting base 22b is elastically snapped into the mounting groove 13 through the first elastic snap-fit ​​member 2221 and the second elastic snap-fit ​​member 2222.

[0284] Optionally, the first direction X intersects with the extension direction of the transmission channel 11b. In this way, the elastic snap-fit ​​222 can be disposed on both sides of the width direction of the transmission channel 11b, thereby avoiding the elastic snap-fit ​​222 from causing obstruction within the transmission channel 11b.

[0285] Optionally, the elastic snap-fit ​​member 222 includes a connecting portion 222a and an ear plate 222b connected together. One end of the connecting portion 222a, away from the ear plate 222b, is connected to the side of the mounting base 22b. The end of the ear plate 222b, away from the connecting portion 222a, extends outward at an angle relative to the side of the mounting base 22b. Based on this, by pressing the ear plate 222b, the connecting portion 222a can be deformed, reducing the space occupied by the elastic snap-fit ​​member 222 along the first direction X, thereby allowing the mounting base 22b to smoothly enter the mounting groove 13. After the mounting base 22b enters the mounting groove 13, pressing the ear plate 222b stops, and the connecting portion 222a elastically recovers its shape, elastically snapping into the mounting groove 13.

[0286] Optionally, the outer side of the connecting part 222a is provided with a protrusion 222c that protrudes relative to the outer surface of the connecting part 222a. The protrusion 222c abuts against the mounting groove 13, thereby improving the stability of the engagement between the mounting base 22b and the mounting groove 13.

[0287] Furthermore, the protrusion 222c is provided with a guide surface 222d. One end of the guide surface 222d is connected to the outer surface of the connecting portion 222a, and the other end extends in a direction away from the outer surface of the connecting portion 222a, with the extension direction inclined upward relative to the bottom wall of the mounting groove 13. Based on this, during the elastic snap-fit ​​process, under the inclined guiding action of the guide surface 222d, the mounting base 22b can be snapped into the mounting groove 13 more smoothly. At the same time, due to the provision of the protrusion 222c, the mounting base 22b can be stably snapped into the mounting groove 13 without applying external force to the connecting portion 222a.

[0288] In some embodiments, the host 10 has opposing inner and outer sides, which are closed and isolated from each other. The mounting slot 13 and the transmission channel 11b are located on the outer side. The inner side can be configured to accommodate mechanical and electrical components required for printing. In this way, contaminants cleaned off the printer 1 by the cleaning component 21 can be prevented from entering the inner side of the host 10 and affecting the lifespan of the host 10.

[0289] Referring again to Figures 32 and 33, in some embodiments, the mounting groove 13 has a third sidewall 133 and a fourth sidewall 134 opposite to each other along the second direction Y, wherein the width of the mounting base 22b along the second direction Y is smaller than the width of the mounting groove 13 along the second direction Y. Optionally, the transmission channel 11b has a transmission segment that coincides with the mounting groove 13, and the second direction Y is parallel to the extension direction of the transmission segment. Thus, the assembly and disassembly process of the mounting base 22b is less likely to interfere with the third sidewall 133 and the fourth sidewall 134 of the mounting groove 13, thereby making the assembly and disassembly process of the mounting base 22b smoother.

[0290] Optionally, the difference between the width of the mounting base 22b along the second direction Y and the width of the mounting groove 13 along the second direction Y is 1mm-6mm, for example, 1.2mm, 2mm, or 3mm. This facilitates the installation and removal of the mounting base 22b. Simultaneously, the smaller gap between the mounting base 22b and the groove wall of the mounting groove 13 prevents contaminants cleaned from the printer 1 by the cleaning component 21 from falling into the mounting groove 13, thereby preventing excessive contaminant residue that could hinder the installation and removal of the mounting base 22b.

[0291] Referring to Figures 30 and 31, optionally, a limiting rib 222e is provided on one side of the mounting base 22b along the second direction Y, or limiting ribs 222e are provided on both opposite sides of the mounting base 22b along the second direction Y. By using the limiting rib 222e to abut against the side wall of the mounting groove 13 facing the second direction Y, the mounting base 22b can be prevented from shaking.

[0292] Referring to Figures 26 and 34, in some embodiments, the printer 1 further includes a limiting member 30a, configured to restrict the printable part 2 within the cleaning range of the cleaning component 20c. In this way, the printable part 2 can be stably kept within the cleaning range of the cleaning component 20c, thereby ensuring a good cleaning effect.

[0293] In some embodiments, the printer 1 further includes a cover 40 connected to the host 10, with a limiting member 30a disposed on the cover 40. When the cover 40 is closed to the host 10, the limiting member 30a restricts the printable part 2 within the cleaning range of the cleaning component 20c. Thus, the action of closing the cover 40 simultaneously restricts the printable part 2 with the limiting member 30a, simplifying the operation and improving the user experience.

[0294] In some embodiments, the printer 1 further includes a telescopic member 31. The telescopic method of the telescopic member 31 includes elastic telescopic and multi-stage telescopic. The elastic telescopic and multi-stage telescopic structures are referenced in related technologies and will not be described in detail here. The telescopic member 31 is connected to a limiting member 30a. The limiting member 30a can move in the direction toward the cleaning component 20c to confine the printable part 2 within the cleaning range of the cleaning component 20c. The limiting member 30a can also move in the direction away from the cleaning component 20c to release the restriction on the printable part 2. Thus, the limiting member 30a can flexibly adjust its position according to the size of the printable part 2, expanding its applicability. Furthermore, the telescopic design of the limiting member 30a ensures a good limiting effect while avoiding severe compression of the printable part 2, which could affect the printing effect.

[0295] Referring again to Figures 26 and 34, in an exemplary embodiment, printer 1 includes a host 10, a cover 40, a cleaning assembly 20c, and a limiting member 30a. The host 10 has a transport channel 11b and a printing assembly 12c. The transport channel 11b is configured to transport a workpiece 2 to be printed, and the printing assembly 12c is configured to print the workpiece 2 transported by the transport channel 11b. The cover 40 is connected to the host 10. When the cover 40 is closed to the host 10, components such as the cleaning assembly 20c and the limiting member 30a are covered. The cleaning assembly 20c is disposed within the transport channel 11b and upstream of the printing assembly 12c to clean the workpiece 2 before it is transported to the printing assembly 12c.

[0296] The transmission channel 11b has a first opening 111 exposing its bottom wall. The cleaning assembly 20c includes a cleaning component 21 disposed within the transmission channel 11b corresponding to the first opening 111. The cleaning component 21 has a second opening 211 configured to allow the printable part 2 to enter the cleaning component 21. The second opening 211 faces away from the bottom wall of the transmission channel 11b, so that the second opening 211 can be partially or completely exposed through the first opening 111. In this way, the printable part 2 can be placed into the cleaning component 21 from top to bottom.

[0297] The limiting member 30a is connected to the cover 40 and is block-shaped. When the cover 40 is closed on the host 10, the limiting member 30a elastically abuts against the cleaning member 21, which can prevent the printable part 2 from detaching from the cleaning member 21 through the second opening 211, while also reducing the squeezing force on the printable part 2.

[0298] Example 6

[0299] Referring to Figures 35 to 37, an embodiment of the wire marking printer 1 provided in this application includes a main unit 10, a cutting component 20, and a limiting component 30b. The main unit 10 includes a housing, the shape of which is not limited. The housing provides mounting references and accommodating space for other mechanical and electrical components of the wire marking printer 1.

[0300] The main unit 10 is equipped with a tube-laying groove 11 configured to hold the wire tube 2. The form of the tube-laying groove 11 is not limited and is selected according to the layout design requirements of the main unit 10. For example, the extension path of the tube-laying groove 11 can be a straight line, a broken line, or a curve. The width of the tube-laying groove 11 is uniform or varies along the extension direction. The depth of the tube-laying groove 11 is uniform or varies along the extension direction. The width direction and the depth direction of the tube-laying groove 11 are intersecting, for example, perpendicular.

[0301] Referring further to Figure 38, the pipe-laying groove 11 has a pipe outlet 111. The pipe outlet 111 is a channel formed by the pipe-laying groove 11 penetrating the end face of the housing along the extension direction of the pipe-laying groove 11. The shape of the channel is the same as the cross-sectional shape of the pipe-laying groove 11 on the plane where the end face is located, such as a circle, ellipse, rectangle, triangle, trapezoid, or an irregular shape composed of these shapes.

[0302] The cutting component 20 is mounted on the main unit 10, and is partially or entirely located within the tube placement groove 11 to cut the printed wire tube 2. The shape, material, installation method, and driving method of the cutting motion of the cutting component 20 are described in reference to relevant technologies and will not be elaborated here.

[0303] Referring to Figures 36 to 38, the limiting component 30b is disposed on the main unit 10. A portion of the limiting component 30b blocks the space between the outlet 111 and the cutting component 20, or the entire limiting component 30b blocks the space between the outlet 111 and the cutting component 20, thereby preventing foreign objects from entering the discharge slot 11 through the outlet 111. These foreign objects include the operator's fingers, debris, etc.

[0304] Referring further to Figures 39 and 40, while the limiting component 30b limits the movement, a preset gap H is also provided in the tube-laying groove 11, through which the wire tube 2 can extend out of the tube-laying groove 11. This preset gap H can be a fixed size gap, or it can be a variable size gap, ensuring that the wire tube 2 can smoothly extend out of the tube-laying groove 11.

[0305] Based on this, the limiting component 30b is used to restrict foreign objects from entering the tube release groove 11 through the tube outlet 111 and contacting the cutting component 20. The tube release groove 11 is provided with a preset gap H for the wire number tube 2 to extend out of the tube release groove 11. This ensures smooth tube release while preventing fingers from entering the tube release groove 11 through the tube outlet 111 and being cut by the cutting component 20. It also prevents some debris from entering the tube release groove 11 through the tube outlet 111 and contaminating the tube release groove 11.

[0306] Optionally, the host 10 is equipped with a printing assembly, which includes a print head and a ribbon. During printing, the ribbon is located between the print head and the wire marking tube 2. The print head presses the ribbon against the surface of the wire marking tube 2 to achieve printing. The wire marking tube 2 is also called a sleeve or wire marking sleeve. The wire marking is printed on the sleeve by the wire marking tube printer 1 and configured as a wiring identifier.

[0307] Referring to Figures 37 to 40, in some embodiments, the pipe-laying groove 11 has two side walls facing each other along its width direction, and the outlet 111 is located at one end of the longitudinal extension direction of the pipe-laying groove 11. The width direction of the pipe-laying groove 11 intersects with the longitudinal extension direction of the pipe-laying groove 11. It should be noted that although the width direction of the pipe-laying groove 11 is different at different positions in the extension direction of the pipe-laying groove 11 when the extension path of the pipe-laying groove 11 is not straight, the width direction of the pipe-laying groove 11 intersects with the longitudinal extension direction of the pipe-laying groove 11 at any position in the extension direction of the pipe-laying groove 11, for example, perpendicularly.

[0308] The limiting component 30b includes a limiting member 31, which is connected to the main unit 10, and a preset gap H is provided between the limiting member 31 and one side of the groove wall. Based on this, the limiting member 31 can restrict foreign objects from entering the tube release groove through the outlet 111, while the tube release can extend out of the tube release groove 11 through the preset gap H, thereby ensuring smooth tube release of the wire tube 2 while preventing fingers from being cut by inserting into the tube release groove 11.

[0309] In some embodiments, the limiting member 31 is movably connected to the host 10 to adjust the size of the preset gap H. In this way, the size of the preset gap H can be adjusted according to the size of the wire tube 2, its movement state, etc., thereby expanding the applicability of the wire tube printer 1 and improving the smoothness of tube output.

[0310] Optionally, the movable connection method includes telescopic connection and rotational connection. Telescopic components include elastic telescopic and multi-stage telescopic. For elastic telescopic and multi-stage telescopic structures, please refer to relevant technologies, which will not be elaborated here.

[0311] In some embodiments, the limiting member 31 is rotatably connected to the main unit 10 to adjust the size of the preset gap H. Thus, when the wire tube 2 moves within the tube placement groove 11, the limiting member 31 can rotate along with the movement of the wire tube 2, thereby flexibly adjusting the size of the preset gap H according to the movement of the wire tube 2, making the outlet of the wire tube 2 smoother.

[0312] Referring to Figures 39 to 42, in some embodiments, the limiting component 30b includes a limiting member 31, a connecting post 32, and a torsion spring 33. The connecting post 32 is connected to the limiting member 31 and rotatably connected to the host 10. The torsion spring 33 includes a main body 331, a first connecting arm 332, and a second connecting arm 333. The first connecting arm 332 and the second connecting arm 333 are respectively connected to the two ends of the main body 331. The main body is sleeved on the connecting post 32, the first connecting arm 332 is connected to the limiting member 31, and the second connecting arm 333 is connected to the host 10. Thus, during the rotation of the limiting member 31 relative to the host 10, the included angle between the first connecting arm 332 and the second connecting arm 333 of the torsion spring 33 changes. For example, when the included angle decreases, the torsion spring 33 will generate a restoring force that tends to restore the included angle to a larger value.

[0313] Based on this, during the movement of the wire tube 2 within the tube placement groove 11, it exerts a squeezing force on the limiting member 31. This squeezing force drives the limiting member 31 to rotate relative to the main unit 10, causing the torsion spring 33 to generate a rebound force. This rebound force, through the limiting member 31, is directed towards the wire tube 2, creating a mutual abutting force between the wire tube 2 and the limiting member 31. This maintains the size of the preset gap H within the tube placement groove 11 at a state that allows the wire tube 2 to pass through in the tube exit direction, ensuring smooth exit of the wire tube 2 while preventing fingers from being cut by inserting them into the tube placement groove 11. Furthermore, when the external force on the limiting member 31 is removed, for example, when the wire tube 2 has completely left the tube placement groove 11, the limiting member 31 can rotate in the opposite direction to reset under the rebound force of the torsion spring 33.

[0314] Referring to Figures 41 and 42, in some embodiments, the limiting member 31 is provided with a second limiting part 312, and the main unit 10 is provided with a third limiting part 313. The second limiting part 312 and the third limiting part 313 are coupled to restrict the movement of the limiting member 31 relative to the main unit 10 in directions other than the rotation direction. In this way, the rotation of the limiting member 31 is more stable, thereby making the tube exiting process of the wire tube 2 more stable.

[0315] Optionally, both the second limiting part 312 and the third limiting part 313 are constructed in a U-shape and are inverted and snapped together to achieve coupling between them. This results in a simple structure and low cost.

[0316] In some embodiments, the limiting component 30b includes a limiting member 31 connected to the host 10. The limiting member 31 has an initial position and an extreme position. The preset gap H when the limiting member 31 is in the initial position is smaller than the preset gap H when the limiting member 31 is in the extreme position. Thus, when the limiting member 31 is in the initial position, the preset gap H is smaller, which can limit foreign objects from entering the discharge slot 11 through the outlet 111 to a greater extent. When the limiting member 31 is in the extreme position, the preset gap H is larger, and the wire tube 2 can exit more smoothly. At the same time, since the wire tube 2 acts as a block at the outlet 111, it can also limit foreign objects from entering the discharge slot 11 through the outlet 111.

[0317] In some embodiments, when the limiting member 31 is in the initial position, the width of the preset gap H along the width direction of the tube placement groove 11 ranges from 0.1mm to 15mm. For example, the width of the preset gap H is 0.5mm, 1mm, or 5mm. Thus, the preset gap H is relatively small, allowing the limiting member 31 to restrict small objects from entering the tube placement groove 11 through the outlet 111.

[0318] Referring to Figures 39 and 40, in some embodiments, a boss 112 protrudes from the bottom wall of the pipe-laying groove 11. When the limiting member 31 is in its initial position, the side of the limiting member 31 facing away from the outlet 111 abuts against the boss 112 to restrict the limiting member 31 from exceeding the initial position in the direction away from the outlet 111. Thus, when an external object exerts a force on the limiting member 31 toward the pipe-laying groove 11, due to the abutment of the boss 112 against the limiting member 31, the limiting member 31 will not exceed the initial position in the direction away from the outlet 111. That is, the limiting member 31 does not change the size of the preset gap H with the force of the external object, thereby ensuring that the limiting member 31 maintains a state that can restrict the external object from entering the pipe-laying groove 11 through the outlet 111.

[0319] In some embodiments, the protrusion height of the boss 112 along the depth direction of the tube placement groove 11 ranges from 0.5mm to 2mm, for example, the protrusion height of the boss 112 is 0.6mm, 1mm, or 1.5mm. The depth direction of the tube placement groove 11 intersects with both the width direction and the longitudinal extension direction of the tube placement groove 11. Exemplarily, the depth direction, width direction, and longitudinal extension direction of the tube placement groove 11 are all perpendicular to each other. Thus, along the depth direction of the tube placement groove 11, the contact range between the boss 112 and the limiting member 31 is sufficient, allowing the limiting member 31 to stably abut against the boss 112. Simultaneously, the height of the boss 112 is not excessive, thereby ensuring smooth tube delivery.

[0320] Referring to Figures 41 and 42, in some embodiments, the main unit 10 is provided with a stop post 113, and the limiting member 31 is provided with a first limiting part 311. The stop post 113 can abut against the first limiting part 311 to limit the limiting member 31 from exceeding the limit position in the direction toward the outlet 111. Thus, during the outlet process of the wire tube 2, the limiting member 31 can rotate with the movement of the wire tube 2 to adjust the size of the preset gap H. At the same time, due to the abutment action of the stop post 113, the adjustment of the preset gap H by the limiting member 31 is limited to the set range, thereby preventing the limiting member 31 from interfering with other parts of the main unit 10.

[0321] Referring to Figures 39 to 42, in some embodiments, the main unit 10 has an inner side 114 and an outer side 115, with the tube slot 11 located on the outer side 115. A portion of the limiting member 31 is located on the inner side 114, and another portion is located on the outer side 115. A stop post 113 is located on the inner side 114, and a first limiting portion 311 is provided on the portion of the limiting member 31 located on the inner side 114. In this way, the stop post 113 and a portion of the limiting member 31 are hidden within the inner side 114 of the main unit 10, making full use of the space within the inner side 114 of the main unit 10 and making the space on the outer side 115 of the main unit 10 neater.

[0322] Referring to Figures 43 and 44, in some embodiments, the main unit 10 has a cavity 116 located beside the tube placement groove 11. The groove wall of the tube placement groove 11 has an opening 117 communicating with the cavity 116 and the tube placement groove 11. A portion of the limiting member 31 is accommodated in the cavity 116, and another portion extends into the tube placement groove 11 through the opening 117. Thus, during the rotation of the limiting member 31, the cavity 116 can accommodate the portion of the limiting member 31 that moves out of the tube placement groove 11.

[0323] Referring again to Figures 43 and 44, in some embodiments, the opening 117 has a first sidewall 1171 and a second sidewall 1172 that are opposite to each other along the longitudinal extension direction of the pipe channel 11, with the first sidewall 1171 being further away from the outlet 111 than the second sidewall 1172. The limiting member 31 has a first surface 314 and a second surface 315 that are opposite to each other, with the first surface 314 being further away from the outlet 111 than the second surface 315. The limiting member 31 is movably connected to the host 10 to adjust the size of the preset gap H. During the movement of the limiting member 31, the first sidewall 1171 can abut against the first surface 314 to limit the range of movement of the limiting member 31 in the direction away from the outlet 111. Thus, the first sidewall 1171 of the opening 117 can abut against the first surface 314 of the limiting member 31, so that the rotation angle of the limiting member 31 is limited within a preset range, thereby allowing the limiting member 31 to maintain a state that can restrict foreign objects from entering the discharge slot 11 through the outlet 111.

[0324] Optionally, compared to the initial state of the limiting member 31, the first sidewall 1171 abuts against the first surface 314, and the limiting member 31 is further away from the outlet 111, for example, the rotation angle is larger. In other words, when the limiting member 31 is in the initial state, the first sidewall 1171 and the first surface 314 are spaced apart; when the condition preventing the limiting member 31 from exceeding the initial position in the direction away from the outlet 111 fails, for example, when the boss 112 is worn, the first sidewall 1171 can abut against the first surface 314 to limit the rotation angle of the limiting member 31 beyond the initial position. In this way, a double guarantee is formed to prevent the limiting member 31 from exceeding the initial position in the direction away from the outlet 111, thereby improving the sustainability of the cut prevention effect.

[0325] In some embodiments, the height of the opening 117 is greater than the height of the limiting member 31 along the depth direction of the tube placement groove 11. The depth direction of the tube placement groove 11 intersects with both the width direction and the longitudinal extension direction of the tube placement groove 11; for example, the depth direction, width direction, and longitudinal extension direction of the tube placement groove 11 are all perpendicular to each other. Thus, the limiting member 31 will not contact the top wall of the opening 117 during rotation, preventing jamming and ensuring smoother rotation.

[0326] In some embodiments, the limiting member 31 has a third surface 316 facing the bottom wall of the tube placement groove 11. At any position during the rotation of the limiting member 31, the third surface 316 is located above the bottom wall of the tube placement groove 11, and the orthographic projection of the third surface 316 on the plane where the bottom wall of the groove is located overlaps with the bottom wall of the groove, thereby preventing the limiting member 31 from falling below the bottom wall of the limiting groove after rotating into the opening 117, and thus preventing the limiting member 31 from getting stuck at the opening 117.

[0327] Referring to Figures 39 and 40, in some embodiments, the limiting component 30b includes a first rolling rubber roller 34, which is configured to roll into contact with the wire gauge tube 2 during tube exit. Thus, during tube exit, the first rolling rubber roller 34 rolls as the wire gauge tube 2 moves, reducing the frictional force on the wire gauge tube 2 and making the tube exit process smoother.

[0328] Referring again to Figures 39 and 40, in some embodiments, a second rolling rubber roller 40b is provided inside the tube-feeding groove 11. The second rolling rubber roller 40b is configured to roll and contact the wire gauge tube 2 during tube ejection. The second rolling rubber roller 40b and the limiting component 30b are located on opposite sides of the width direction of the tube-feeding groove 11, and the width direction of the tube-feeding groove 11 intersects with the longitudinal extension direction of the tube-feeding groove 11. Thus, during tube ejection, the second rolling rubber roller 40b rolls along with the movement of the wire gauge tube 2, reducing the frictional force on the wire gauge tube 2 and making the ejection process smoother. Simultaneously, the fact that the second rolling rubber roller 40b and the limiting component 30b are located on opposite sides of the width direction of the tube-feeding groove 11 ensures that their arrangement does not interfere with each other.

[0329] In one exemplary embodiment, the wire marking tube printer 1 includes a main unit 10, a cutting component 20, a limiting component 30b, and a second rolling roller 40b. The main unit 10 is provided with a tube placement groove 11 configured to place the wire marking tube 2, the tube placement groove 11 having an outlet 111 for the wire marking tube 2 to exit, the cutting component 20 is disposed on the main unit 10, and the cutting component 20 is partially or entirely located within the tube placement groove 11 to cut the printed wire marking tube 2.

[0330] The limiting component 30b includes a limiting member 31 and a first rolling rubber roller 34. The limiting member 31 is connected to the main unit 10, and a preset gap H is provided between the limiting member 31 and one side wall of the tube placement groove 11 for the wire gauge tube 2 to extend out of the tube placement groove 11. The first rolling rubber roller 34 is rotatably connected to the side of the limiting member 31 facing the preset gap H.

[0331] The second rolling rubber roller 40b is rotatably connected to the side wall of the tube release groove 11 facing the limiting member 31. Along the extending direction of the tube release groove 11, the second rolling rubber roller 40b is offset from the first rolling rubber roller 34, so as to achieve a continuous rolling traction effect and increase the obstruction of foreign objects entering the tube release groove 11 through the outlet 111.

[0332] Based on the above embodiments, the wire tube 2 can smoothly exit through the outlet 111 along the outlet direction, while foreign objects such as the operator's fingers cannot enter the tube slot 11 through the outlet 111, thereby ensuring smooth tube exit while providing a good anti-cut effect.

[0333] Example 7

[0334] As shown in Figures 45-49, it includes the main body mechanism 1, the inlet guide mechanism 2, and the outlet guide mechanism 3.

[0335] The main body 1 includes a middle shell 11, on which a wire tube groove 12 is formed.

[0336] The inlet guide mechanism 2 includes an inlet roller 21b located at the inlet of the conduit groove 12, the inlet roller 21b being configured to abut against the side wall of the conduit.

[0337] The tube guide mechanism 3 includes a tube outlet roller 31b located at the outlet of the tube groove 12, the tube outlet roller 31b being configured to abut against the side wall of the tube.

[0338] In use, the middle shell 11, as the main part of the wire marking tube printer, contains key components such as the printing mechanism and control circuit. It provides support and a mounting base for the entire anti-clogging tube structure. The inlet roller 21b is located at the inlet of the wire tube slot 12. When the wire tube is inserted into the wire marking tube printer from the outside, it first passes through the inlet roller 21b. The inlet roller 21b abuts against the side wall of the wire tube. As the wire tube moves forward, friction is generated between the wire tube and the inlet roller 21b, causing the inlet roller 21b to rotate. The rotation of the inlet roller 21b guides the wire tube smoothly into the wire marking tube printer, ensuring the accurate positioning of the wire tube and preventing the wire tube from bending, twisting, or deviating from the correct path at the inlet. At the same time, the abutment of the inlet roller 21b can also apply a certain pressure to the wire tube, keeping the wire tube in a stable forward direction. It is located at the outlet of the middle shell 11. After the wire tube has completed printing through the printing mechanism, it leaves the wire marking tube printer from the outlet roller 31b. The tube ejector roller 31b abuts against the side wall of the tube. Similarly, as the tube moves, friction is generated between it and the ejector roller 31b, causing the ejector roller 31b to rotate. This rotation guides the tube smoothly out of the wire marking printer, preventing blockage or tangling at the exit point. The contact between the ejector roller 31b and the tube also helps maintain tension, ensuring the tube remains neat after exiting the wire marking printer.

[0339] In this application, the inlet roller 21b ensures that the tube accurately enters the printing mechanism when it enters the wire marking printer, preventing the tube from getting stuck at the inlet due to bending, twisting, or inaccurate positioning. The outlet roller 31b guides the tube smoothly out of the wire marking printer, preventing the tube from accumulating or tangling at the outlet, thereby reducing the risk of blockage. Through the synergistic action of the inlet guide mechanism 2 and the outlet guide mechanism 3, blockage of the tube during printing is effectively prevented, improving the printing efficiency and stability of the wire marking printer.

[0340] To facilitate smoother pipe exit, please refer to Figure 46. In an optional embodiment, the pipe exit guide mechanism 3 further includes a pipe exit floating pressure block 32c disposed at the outlet of the pipe groove 12. The pipe exit floating pressure block 32c is configured to abut against the side wall of the pipe. The pipe groove 12 is provided with a fixing component 33 configured to fix the pipe exit floating pressure block 32c.

[0341] During use, as the tubing approaches the outlet of the tubing slot 12, adjust the position of the tube-exit floating pressure block 32c so that it abuts against the side wall of the tubing. The function of the tube-exit floating pressure block 32c is to increase the pressure on the tubing, further stabilizing its position. During printing, the tubing may be affected by various external forces, causing it to wobble. By abutting against the tubing, the tube-exit floating pressure block 32c reduces the amplitude of the wobble, ensuring that the tubing remains in the correct position so that the printed content can be accurately printed onto the tubing. Because the tube-exit floating pressure block 32c has a certain degree of elasticity and adjustability, it can adapt to tubing of different diameters. Regardless of changes in tubing size, the tube-exit floating pressure block 32c can adjust its position and pressure to maintain close contact with the tubing, providing stable support. The function of the fixing component 33 is to ensure that the tube-exit floating pressure block 32c always maintains pressure on the tubing, thereby maintaining the stability of the tubing throughout the printing process. Even if the tube is subjected to the pulling force of the printing mechanism or other external forces, the tube floating pressure block 32c can maintain stable support for the tube through the fixing action of the fixing component 33.

[0342] To secure the outlet floating pressure block 32c, please refer to Figure 47. In an optional embodiment, the fixing component 33 includes a bolt 331 threaded onto the conduit groove 12, and the outlet floating pressure block 32c is provided with a through hole 332 through which the bolt 331 passes.

[0343] During use, after the outlet tube floating pressure block 32c is adjusted to the appropriate position, the bolt 331 is passed through the through hole 332 on the outlet tube floating pressure block 32c, and the bolt 331 is rotated. Since the bolt 331 is threadedly connected to the tube groove 12, as the bolt 331 rotates, it gradually screws into the tube groove 12, and the head of the bolt 331 gradually approaches the outlet tube floating pressure block 32c. As the bolt 331 continues to screw in, the head of the bolt 331 applies pressure to the outlet tube floating pressure block 32c. This pressure causes the outlet tube floating pressure block 32c to press tightly against the side wall of the tube, thereby fixing the position of the outlet tube floating pressure block 32c. During the printing process, the tube may be affected by external forces such as tension and vibration from the printing mechanism. However, since the outlet tube floating pressure block 32c is fixed in its current position by the bolt 331, it can continuously provide stable pressure to the tube, preventing the tube from shaking, shifting, or becoming blocked at the outlet.

[0344] If it is necessary to adjust the position of the tubing or replace it with a different size tubing, the bolt 331 can be rotated in the opposite direction, gradually moving the head of the bolt 331 away from the tube outlet floating pressure block 32c. As the bolt 331 is unscrewed, the pressure of the bolt 331 on the tube outlet floating pressure block 32c gradually decreases until the tube outlet floating pressure block 32c can move freely again. At this point, the position of the tube outlet floating pressure block 32c can be readjusted, and then the bolt 331 can be reinserted and rotated to fix it. This adjustability allows the fixing component 33 to adapt to different printing needs and tubing changes.

[0345] To further improve the stability of the floating pressure block 32c, please refer to Figure 47. In an optional embodiment, a washer 34 is fitted on the bolt 331, and the washer 34 is configured to abut against the conduit groove 12.

[0346] During use, the washer 34 fitted on the bolt 331 increases the contact area, disperses pressure, and provides a buffering effect during the process of fixing the floating pressure block 32c of the outlet pipe. This improves the stability and reliability of the connection between the bolt 331 and the conduit groove 12, ensuring that the anti-clogging pipe structure of the wire number tube printer can work stably during use.

[0347] To ensure a tighter fit between the outlet floating pressure block 32c and the conduit, please refer to Figure 47. In an optional embodiment, a spring 35 is provided between the outlet floating pressure block 32c and the conduit groove 12. One end of the spring 35 is connected to the side of the outlet floating pressure block 32c away from the bolt 331, and the other end of the spring 35 is connected to the conduit groove 12. When the spring 35 is in a compressed state, it causes the outlet floating pressure block 32c to tend to move towards the conduit.

[0348] During use, spring 35 remains compressed throughout the printing process, continuously providing pressure to the tube ejection floating block 32c towards the tube. Even when the tube is affected by external forces such as tension or vibration from the printing mechanism, the pressure of spring 35 ensures that the tube ejection floating block 32c maintains tight contact with the tube, preventing the tube from wobbling, shifting, or clogging at the outlet. If the tube diameter changes slightly during printing due to temperature variations or material deformation, the elasticity of spring 35 allows the tube ejection floating block 32c to automatically adjust to adapt to the tube's changes. The compression and extension of spring 35 can compensate for the impact of tube size changes within a certain range, maintaining stable pressure on the tube. In summary, spring 35 between the tube ejection floating block 32c and the tube slot 12 plays a crucial role in the anti-clogging tube structure of the entire tube printer. By providing continuous pressure and adaptive adjustment capabilities, it ensures that the tube ejection floating block 32c maintains tight contact with the tube, improving the stability of the tube at the outlet, preventing clogging and wobbling, and also providing convenience for adjustment and unlocking operations.

[0349] To make the outlet roller 31b more securely fixed, please refer to Figure 49. In an optional embodiment, a roller plate 36 is provided at the outlet of the conduit groove 12, and the outlet roller 31b is fixed on the roller plate 36.

[0350] During use, the roller plate 36 provides a solid mounting base for the tube output roller 31b. It ensures that the tube output roller 31b remains in the correct position during printing, preventing displacement or wobbling due to tube movement or external forces. If the tube output roller 31b malfunctions or needs replacement, the design of the roller plate 36 simplifies maintenance. The tube output roller 31b can be directly removed and installed on the roller plate 36 without requiring extensive adjustments to the entire tube printer structure.

[0351] To prevent foreign objects from entering the wire marking printer, please refer to Figure 48. In an optional embodiment, the outlet of the wire slot 12 is provided with a blocking component 4 configured to block foreign objects from entering the inner shell 11.

[0352] During use, the blocking component 4 at the outlet of the middle shell 11 effectively prevents foreign objects from entering the inside of the wire marking tube printer through physical blocking, size adaptation and positional advantages, protecting the printing mechanism and other key components, and improving the reliability and service life of the wire marking tube printer.

[0353] To prevent foreign objects from entering the wire marking printer, please refer to Figure 49. In an optional embodiment, the blocking assembly 4 includes a stop block 41 rotatably connected to the outlet of the wire tube groove 12. A torsion spring 42a is provided between the stop block 41 and the wire tube groove 12. One end of the torsion spring 42a is connected to the stop block 41, and the other end of the torsion spring 42a is connected to the wire tube groove 12. The torsion spring 42a causes the stop block 41 to tend to rotate in the direction of the tube outlet roller 31b, so that the end of the stop block 41 abuts against the tube outlet roller 31b.

[0354] In use, when printing is required, the tube is introduced into the main body mechanism 1 of the wire marking printer through the tube guide mechanism 2. After passing through the printing area, the tube moves towards the outlet of the middle shell 11. When the tube approaches the outlet, it contacts the stop 41. Due to the thrust of the tube, the stop 41 overcomes the torque of the torsion spring 42a and begins to rotate away from the outlet roller 31b. The tube continues to move forward, pushing the stop 41 to open further. The tube passes through the gap between the stop 41 and the outlet roller 31b, smoothly leaving the wire marking printer. Throughout the printing process, the torsion spring 42a always applies a torque towards the outlet roller 31b to the stop 41. This torque causes the stop 41 to always tend to return to the closed state when there is no thrust from the tube. After the tube has passed, if an external foreign object approaches the outlet of the middle shell 11, the torque of the torsion spring 42a will cause the stop 41 to close quickly, preventing the foreign object from entering. Since the end of the stop 41 abuts against the tube output roller 31b, a relatively enclosed space can be formed, effectively preventing dust, debris and other foreign objects from entering the inside of the wire marking tube printer.

[0355] To reduce wear on the stop 41, referring to Figure 48, in an optional embodiment, a stop wheel is rotatably connected to the end of the stop 41, the stop wheel being configured to abut against the outlet roller 31b.

[0356] In use, when printing is required, the tube is introduced into the main body of the wire marking tube printer 1 through the tube inlet guide mechanism 2. After passing through the printing area, the tube moves towards the outlet of the middle shell 11. As the tube approaches the outlet, it first contacts the stop roller. Due to the thrust of the tube, the stop block 41 overcomes the torque of the torsion spring 42a and begins to rotate away from the outlet roller 31b. Simultaneously, the stop roller rotates with the stop block 41, reducing the friction between the tube and the stop block 41, making it easier for the tube to push the stop block 41 open. In summary, the stop roller, rotatably connected to the end of the stop block 41, plays a role in reducing friction, ensuring smooth opening and closing, and enhancing the blocking effect in the anti-clogging structure of this wire marking tube printer. Working in conjunction with the stop block 41 and the torsion spring 42a, it improves the reliability and service life of the wire marking tube printer.

[0357] To reduce the possibility of slippage, please refer to Figure 49. In an optional embodiment, the outer sides of the inlet roller 21b, the outlet roller 31b, and the stop roller are all provided with anti-slip layers.

[0358] During use, the inlet roller 21b, the outlet roller 31b, and the anti-slip layer on the outside of the stop roller play an important role in increasing friction during the insertion, output, and blocking of foreign objects of the tube, respectively, thereby improving the stability and reliability of the anti-clogging tube structure of the tube printer.

[0359] To better understand this application, the working principle of the anti-clogging tube structure of a wire marking tube printer is described in detail below with reference to Figures 45-49: The middle shell 11, as the main part of the wire marking tube printer, includes key components such as the printing mechanism and control circuit. It provides support and installation foundation for the entire anti-clogging tube structure. The inlet roller 21b is located at the inlet of the wire tube slot 12. When the wire tube is inserted into the wire marking tube printer from the outside, it first passes through the inlet roller 21b. The inlet roller 21b abuts against the side wall of the wire tube. When the wire tube moves forward, friction is generated between the wire tube and the inlet roller 21b, causing the inlet roller 21b to rotate. The rotation of the inlet roller 21b can guide the wire tube smoothly into the inside of the wire marking tube printer, ensuring the accurate position of the wire tube and preventing the wire tube from bending, twisting, or deviating from the correct path at the inlet. At the same time, the abutment of the inlet roller 21b can also apply a certain pressure to the wire tube, keeping the wire tube in a stable forward direction. It is located at the outlet of the middle shell 11. After the wire tube completes printing via the printing mechanism, it exits the wire marking printer from the exit roller 31b. The exit roller 31b abuts against the side wall of the wire tube. Similarly, as the wire tube moves, friction is generated between it and the exit roller 31b, causing the exit roller 31b to rotate. This rotation guides the wire tube smoothly out of the wire marking printer, preventing blockage or tangling at the exit point. The contact between the exit roller 31b and the wire tube also helps maintain wire tension, ensuring the wire tube remains neat after exiting the wire marking printer.

[0360] Example 8

[0361] As shown in Figures 50 and 51, it includes a main body mechanism 1, a printing mechanism 2, and a testing mechanism 3.

[0362] The main structure includes a middle shell 11 and a channel 12 disposed within the middle shell 11, the channel 12 being configured to accommodate wire tubes.

[0363] The printing mechanism 2 includes a printhead substrate 21 and a printing roller 22 disposed in the middle shell 11, and the printhead substrate 21 and the printing roller 22 are respectively located on both sides of the channel 12.

[0364] The detection mechanism 3 is located inside the middle shell 11 and is situated on one side of the printing roller 22. The channel 12 passes between the detection mechanism 3 and the printing roller 22. The detection mechanism 3 is configured to detect whether the wire marking tube deviates from the channel 12.

[0365] In use, the middle shell 11 serves as the outer casing of the entire wire marking tube printer, providing support and protection for the various internal mechanisms. The channel 12 provides a clear path for the wire, ensuring it passes accurately through the printing area. The printhead substrate 21 and the printing roller 22 are located on opposite sides of the channel 12. As the wire moves within the channel 12, the printhead on the printhead substrate 21 performs printing operations on the wire surface, while the printing roller 22 assists in pressing and propelling the wire forward. The detection mechanism 3 is located inside the middle shell 11, to one side of the printing roller 22. This location allows the detection mechanism 3 to promptly detect whether the wire is clogged after passing through the printing area. Once cloggedness is detected, the wire marking tube printer can quickly take action.

[0366] In this application, the detection mechanism 3 is located inside the middle shell 11 and on one side of the printing roller 22. This position allows the detection mechanism 3 to detect whether the tube is clogged after the tube passes through the printing area. Once the tube is clogged, the tube printer can take measures quickly, which enables the operator to respond to the problem quickly and reduce the troubleshooting time.

[0367] To ensure smooth rotation of the printing roller 22, please refer to Figure 50. In an optional embodiment, the printing roller 22 is rotatably connected to the main body mechanism 1. A gap 41a is provided between the inner shell 11 and the cylindrical surface of the printing roller 22. The gap 41a allows the printing mechanism 2 to rotate and communicates with the channel 12.

[0368] In use, the printing roller 22 is rotatably connected to the main body mechanism 1. This rotatable connection ensures smooth rotation of the printing roller 22 during operation and reduces friction during rotation, minimizing energy loss and component wear, thus providing a stable foundation for subsequent printing operations. A gap 41a is provided between the inner shell 11 and the cylindrical surface of the printing roller 22. This gap 41a is specifically designed to accommodate the rotation of the printing mechanism 2.

[0369] To facilitate the installation of the detection mechanism 3, please refer to Figure 50. In an optional embodiment, the middle shell 11 is provided with a mounting groove, and the detection mechanism 3 is disposed in the mounting groove, with the detection mechanism 3 on the side close to the gap 41a.

[0370] In use, the mounting slot provided inside the middle shell 11 provides a specific installation position and space for the detection mechanism 3, so that the detection mechanism 3 can be accurately and stably placed in the predetermined position.

[0371] To monitor for blockages in the pipeline, please refer to Figure 50. In an optional embodiment, the detection mechanism 3 includes a movable component and a monitoring component. The movable component is rotatably connected to the mounting slot, and the monitoring component is configured to monitor the position of the movable component.

[0372] During use, the movable component is rotatably connected within the mounting slot, allowing it to rotate within a certain range around a specific axis. If a blockage occurs in the pipeline during printing, the rotatably connected component will rotate. A monitoring component continuously monitors the positional changes of the movable component and feeds the relevant data back to the control system. The control system uses this data to infer the internal operating status of the printing equipment.

[0373] To monitor for blockages in the pipeline, please refer to Figure 50. In an optional embodiment, the movable component includes a swing arm 31c and a retainer 32b. The swing arm 31c is rotatably connected to the mounting groove, and the retainer 32b is located on the side of the swing arm 31c near the printing roller 22.

[0374] In use, the swing arm 31c is rotatably connected to the mounting slot, allowing it to rotate flexibly within a certain angle range around the axis of the bearing seat. This rotatable connection enables the swing arm 31c to produce a sensitive rotational response to external forces or environmental changes, thus becoming an important basis for detecting relevant physical quantities or state changes during the printing process. The baffle 32b is located on the side of the swing arm 31c closest to the printing roller 22. During the rotation of the printing roller 22, various physical phenomena or state changes occur, and the baffle 32b can interact with these phenomena and convert them into the rotational motion of the swing arm 31c.

[0375] To monitor the position of the swing arm 31c, please refer to Figure 50. In an optional embodiment, the monitoring component includes a control element and a detector element. The control element is configured to control the dwell position of the swing arm 31c, and the detector element is configured to detect the dwell position of the swing arm 31c.

[0376] During use, the controller keeps the swing arm 31c in its initial detection or calibration position while the printing equipment is running. As the printing roller 22 rotates and the printing mechanism 2 operates, the swing arm 31c rotates due to various physical forces. The detector continuously monitors the changes in the swing arm 31c's position and transmits this position information to the control system.

[0377] To enable the swing arm 31c to rotate normally, please refer to Figure 51. In an optional embodiment, a pin 33 is fixedly connected inside the middle shell, and the swing arm 31c is sleeved on the pin 33.

[0378] During use, the pin 33 fixedly connected inside the middle shell provides a stable rotation axis for the swing arm 31c, enabling the swing arm 31c to remain stationary when the wire tube passes through normally, and to rotate around the pin 33 when the tube is blocked, thereby triggering the detection and response mechanism to ensure the normal operation and printing quality of the wire tube printer.

[0379] To detect the stopping position of the swing arm 31c, please refer to Figure 51. In an optional embodiment, the detection component 5 includes a slotted sensor 51 disposed in the middle shell. The slotted sensor 51 has a detection slot. The control component 4 is configured to position one end of the swing arm 31c near the slotted sensor 51 within the detection slot.

[0380] During operation, when the tubing moves normally within channel 12, the swing arm 31c remains unaffected by the tubing and maintains the position set by control component 4. One end of the swing arm 31c is always located within the detection slot of slot sensor 51. Slot sensor 51 detects that the swing arm 31c is in the normal position and does not emit any abnormal signals. If the tubing becomes blocked or encounters other obstructions within channel 12, the tubing's movement speed will slow down or stop. At this time, the tubing may exert pressure on the retaining wall 32b on the swing arm 31c, causing the swing arm 31c to rotate. As the swing arm 31c rotates, the end of the swing arm 31c closest to slot sensor 51 will move out of the detection slot. Slot sensor 51 detects the change in the position of the swing arm 31c and immediately transmits this change signal to the control system of the tubing printer. After receiving the signal transmitted by slot sensor 51, the control system determines that the tubing is blocked. According to the preset program, the control system can take measures such as stopping printing, issuing an alarm, or attempting to automatically handle the blockage to ensure the normal operation and print quality of the tubing printer.

[0381] To ensure that the end of the swing arm 31c remains within the detection groove, please refer to Figure 51. In an optional embodiment, the control component 4 includes a torsion spring 42a and a detection plate 43. The torsion spring 42a is sleeved on the pin 33, with one end connected to the pin 33 and the other end connected to the swing arm 31c. The detection plate 43 is disposed within the detection groove. The torsion spring 42a causes the end of the swing arm 31c near the groove-shaped sensor 51 to abut against the detection plate 43, thereby positioning the end of the swing arm 31c near the groove-shaped sensor 51 within the detection groove.

[0382] During use, when printing is not in progress or the conduit is passing normally, the torsion spring 42a is in a state of torsion. One end of the torsion spring 42a is connected to the pin 33, and the other end is connected to the swing arm 31c. The torque of the torsion spring 42a causes the end of the swing arm 31c near the slotted sensor 51 to abut against the detection plate 43, thus ensuring that this end of the swing arm 31c is located in the detection slot. When the conduit moves normally within the channel 12, since there is no external force configuring the swing arm 31c, the torque of the torsion spring 42a maintains the position of the swing arm 31c. The swing arm 31c always remains in a state where one end is located in the detection slot and abuts against the detection plate 43. The slotted sensor 51 continuously detects that the swing arm 31c is in the normal position and does not emit an abnormal signal. If the conduit becomes blocked or is obstructed in the channel 12, the movement speed of the conduit will slow down or stop. At this time, the conduit may exert pressure on the retaining wall 32b on the swing arm 31c. Due to the pressure of the conduit on the retaining wall 32b, the swing arm 31c begins to rotate, overcoming the torque of the torsion spring 42a. The end of the swing arm 31c closest to the slot sensor 51 gradually moves away from the detection plate 43 and out of the detection slot 511. As the position of the swing arm 31c changes, the slot sensor 51 detects that the swing arm 31c is no longer in contact with the detection plate 43 and has left the detection slot, and immediately transmits this change signal to the control system of the wire marking printer.

[0383] To ensure proper delivery of the tubing, please refer to Figure 51. In an optional embodiment, the printing roller 22 includes a rotating roller 221 rotatably connected within the middle shell 11, with a rubber sleeve 222 fitted over the outer side of the rotating roller 221.

[0384] In use, the rotating roller 221 and the rubber sleeve 222 in the printing roller 22 cooperate with each other. Through the rotation of the rotating roller 221 and the friction of the rubber sleeve 222, the wire tube is pushed and assisted in printing. This simple and effective printing roller 22 improves the printing efficiency and printing quality of the wire tube printer.

[0385] To make the fit between the roller 221 and the rubber sleeve 222 more secure, please refer to Figure 51. In an optional embodiment, the outer ring of the roller 221 is provided with a plurality of engagement teeth 223, and the outer side of the engagement teeth 223 abuts against the inner side of the rubber sleeve 222.

[0386] During use, the meshing teeth 223 on the outer side of the roller 221 abut against the inner side of the rubber sleeve 222, increasing the friction and connection strength between the roller 221 and the rubber sleeve 222, improving the power transmission efficiency, and preventing the rubber sleeve 222 from slipping. This allows the printing roller 22 to push the tube forward more stably during the printing process, improving the printing efficiency and printing quality of the tube printer.

[0387] To facilitate smoother conduit passage, please refer to Figure 51. In an optional embodiment, the retaining wall 32b extends along the outer wall of the sleeve 222.

[0388] When in use, the structural design of the baffle 32b extending along the outer wall of the rubber sleeve 222 allows the baffle 32b to not affect the printing process when the wire tube passes through normally, and to work together with the swing arm 31c to trigger the detection and response mechanism in case of tube blockage, ensuring the normal operation and printing quality of the wire tube printer.

[0389] To make the force on the swing arm 31c more stable, please refer to Figure 51. In an optional embodiment, the swing arm 31c is in the shape of a broken line.

[0390] In use, the zigzag design of the swing arm 31c plays a crucial role in the automatic tube blockage detection structure of the wire marking printer. It better utilizes space, improves stability, enhances force transmission, and facilitates positional change detection, thereby ensuring that the wire marking printer can promptly detect tube blockage during printing and take appropriate measures to guarantee normal printing operation.

[0391] To increase the contact area between the swing arm 31c and the detection plate 43, please refer to Figure 51. In an optional embodiment, the swing arm 31c has an inclined surface 34 at one end near the slotted sensor 51, and the inclined surface 34 abuts against the detection plate 43.

[0392] In use, the swing arm 31c has a bevel 34 at the end near the slotted sensor 51. This design increases the contact stability between the swing arm 31c and the detection plate 43, evenly distributes the torque of the torsion spring 42a, and makes it easier for the slotted sensor 51 to detect position changes when tube blockage occurs. After the tube blockage problem is resolved, the bevel 34 also helps the swing arm 31c to accurately reset, ensuring that the automatic detection structure of the wire marking tube printer can work continuously and stably.

[0393] To better understand this application, the working principle of the automatic detection structure for printing tube blockage in a wire marking tube printer according to this application is described in detail below with reference to Figures 50 and 51: The middle shell 11 serves as the outer shell of the entire wire marking tube printer, providing support and protection for the various internal mechanisms. The channel 12 provides a clear path for the wire tube, ensuring that the wire tube can accurately pass through the printing area. The printhead substrate 21 and the printing roller 22 are located on both sides of the channel 12, respectively. When the wire tube moves within the channel 12, the printhead on the printhead substrate 21 can perform printing operations on the surface of the wire tube, while the printing roller 22 assists in pressing the wire tube and pushing it forward. The detection mechanism 3 is located inside the middle shell 11 and on one side of the printing roller 22. This position allows the detection mechanism 3 to promptly detect whether the wire tube is blocked after it passes through the printing area. Once a blockage is detected, the wire marking tube printer can quickly take measures.

[0394] Example 9

[0395] Please refer to Figure 52, which is a schematic diagram of the structure of a wire marking tube printer in one embodiment of this application. The wire marking tube printer includes a bottom shell 1, a top cover 2, a conveying mechanism 3, a pressing mechanism 4, and a printing mechanism 5.

[0396] A tube slot 11 is formed on the bottom shell 1 for inserting the wire tube 6.

[0397] The upper cover 2 is rotatably mounted on the bottom shell 1 to open or close the pipe placement groove 11;

[0398] The conveying mechanism 3 is configured to convey the wire pipe 6 placed in the pipe placement trough 11.

[0399] The printing mechanism 5 is configured to print the wire number tube 6 in the tube placement groove 11.

[0400] In use, the top cover 2 is opened, the wire marking tube is placed into the tube placement slot 11, and then the top cover 2 is closed. The wire marking tube 6 placed in the tube placement slot 11 is then transported by the conveying mechanism 3. When the wire marking tube 6 passes the position of the printing mechanism 5, the printing mechanism 5 prints the wire marking tube 6 in the tube placement slot 11. This application solves the problem of wire marking tubes not being able to enter the print head or being blocked due to improper tube insertion or excessive tube length in traditional wire marking tube printers by setting an open tube placement slot 11 on the bottom shell 1. This reduces the difficulty of tube placement for users and improves the ease of use of the wire marking tube printer.

[0401] In some embodiments, referring to Figures 52-54, the conveying mechanism 3 includes a conveying roller 31, a rotating plate 32d, a floating roller 33b, and a rotation drive 34. The conveying roller 31 is rotatably disposed on one side of the tube placement groove 11, and the rotating plate 32d is rotatably disposed on the other side of the tube placement groove 11, and can be located in a first position and a second position. The floating roller 33b is rotatably disposed on the rotating plate 32d. When the rotating plate 32d is in the first position, the distance between the floating roller 33b and the conveying roller 31 is a first preset distance. The first preset distance is less than the distance that the tube printer can handle. The minimum supported diameter of the wire tube 6 is the outer diameter of the wire tube. Therefore, the wire tube 6 can be clamped at this time. When the rotating plate 32d is in the second position, the distance between the floating roller 33b and the conveying roller 31 is a second preset distance. The second preset distance is greater than the first preset distance. In this embodiment, the second preset distance is greater than the outer diameter of the wire tube 6 with the maximum supported diameter of the wire tube printer. Thus, any type of wire tube supported by this wire tube printer can be easily placed into the tube placement slot 11. The rotation drive 34 is configured to drive the conveying roller 31 and / or the floating roller 33b to rotate. In some embodiments, the rotation drive 34 can drive the conveying roller 31 to rotate alone. In other embodiments, the rotation drive 34 can drive the floating roller 33b to rotate alone. In other embodiments, the rotation drive 34 can drive the conveying roller 31 and the floating roller 33b to rotate synchronously.

The driven gear 343 is connected to the drive gear 342 via a plurality of transmission gears 344, thereby enabling the drive of the conveyor roller spindle 311.

[0407] When in use, when the top cover is closed, the top cover rotates the rotating plate 32d in conjunction with the rotating plate, which rotates around the shaft 321. At this time, the floating roller shaft gear 333 meshes with the conveyor roller shaft gear 313, and the conveyor roller rubber sheet 312 and the floating roller rubber sheet 332 clamp the wire tube 6. The rotation drive motor 341 drives the drive gear 342 to rotate, and the drive gear 342 drives the driven gear 343 to rotate via several transmission gears 344. The driven gear 343 drives the conveyor roller shaft 311 to rotate, and the conveyor roller shaft 311 drives the conveyor roller shaft gear 313 to rotate. The conveyor roller shaft gear 313 drives the floating roller shaft gear 333 to rotate, thereby realizing the reverse synchronous rotation of the conveyor roller 31 and the floating roller 33b, realizing the function of conveying the wire tube 6.

[0408] In some embodiments, the clamping mechanism 4 is configured to press above the wire tube 6 in the tube release groove 11, thereby preventing the wire tube 6 in the tube release groove 11 from detaching upwards from the tube release groove 11.

When the top cover 2 is closed, the conveying roller and the floating roller 33b clamp the wire marking tube, and the clamping mechanism 4 presses the wire marking tube. The rotating drive component 34 drives the conveying roller 31 and the floating roller 33b to rotate, thereby moving the wire marking tube 6. When the wire marking tube 6 passes the position of the printing mechanism 5, the printing mechanism 5 prints the wire marking tube 6 in the tube placement slot 11, so that different parts of the wire marking tube 6 can be printed. This application can solve the problem that traditional wire marking tube printers may cause the wire marking tube to be unable to enter the print head for printing or become blocked due to incomplete tube insertion or excessive tube length. The wire marking tube printer adopts an open tube placement slot design, which reduces the difficulty of tube placement for users and improves the ease of use of the wire marking tube printer.

[0417] Example 10

[0418] Please refer to Figures 58 to 60. The cleaning structure for the wire tube printer includes: a middle shell 1, a placement frame 2, and a cleaning component 3. The middle shell 1 has an open wire tube routing groove 11. The placement frame 2 includes an elastic outer snap-fit ​​part and a retainer. The elastic outer snap-fit ​​part is configured to connect to the wire tube routing groove 11 and includes at least one outwardly expanding outer snap-fit ​​plate 21. When the outer snap-fit ​​plate 21 is inserted into the wire tube routing groove 11, the outer snap-fit ​​plate 21 is squeezed inward and snaps into the middle shell 1. The retainer is located inside the elastic outer snap-fit ​​part and is configured to maintain the overall shape of the placement frame 2. The retainer is connected to the elastic outer snap-fit ​​part, and the elastic outer snap-fit ​​part can deform relative to the retainer. The cleaning component 3 is disposed inside the retainer. The cleaning component 3 has an opening that is aligned with the opening direction of the wire tube routing groove 11 and is configured to allow the wire tube to enter the interior of the cleaning component 3 from the opening.

[0419] In this device, the middle shell 1 includes an open conduit routing groove 11, configured for the printing conduit to pass through. The placement frame 2 includes an elastic outer snap-fit ​​part and a retainer. The elastic outer snap-fit ​​part includes at least one outer snap-fit ​​plate 21 with outward expansion elasticity. When the outer snap-fit ​​plate 21 is inserted into the conduit routing groove 11, due to space constraints, the outer snap-fit ​​plate 21 will be squeezed and thus contract inward, so that it can be snapped and fixed with the inner wall of the conduit routing groove 11, ensuring the stability of the connection of the placement frame 2. The retainer is located inside the elastic outer snap-fit ​​part, which can maintain and keep the overall structural shape of the placement frame 2 stable. It also allows the elastic outer snap-fit ​​part to deform and move relative to the retainer within a certain range, providing the necessary flexibility and adaptability, so that the cleaning part 3 can be stably fixed in the appropriate position. The cleaning component 3 is located inside the retainer, and its opening direction is consistent with the opening direction of the cable tray 11, so that the cable can easily enter the interior of the cleaning component 3 from the opening for cleaning and maintenance, ensuring that the cable body can contact the cleaning component 3 and be cleaned during the printing process.

[0420] Please refer to Figures 59 and 60. In this embodiment, the elastic outer buckle part includes two symmetrically arranged outer buckle plates 21. The two outer buckle plates 21 achieve a stable connection with the cable tray 11. One end of each of the two outer buckle plates 21 extends from both sides of the cable tray and is provided with a bracket handle 211 so that the user can easily perform installation and disassembly operations.

[0421] Furthermore, the two bracket handles 211 are respectively bent into the two outer buckle plates 21, and the angle formed between the outer side of the bracket handle 211 and the outer side of the outer buckle plate 21 is greater than 90° and less than 180°. This makes the bracket handle 211 form an easy-to-grip protrusion, and the outward bending design significantly improves the convenience of the user when picking up and operating it, reduces the difficulty of applying force, and provides a better operating feel.

[0422] To improve the stability of the placement rack 2 after installation, in this embodiment, a fixing block 212 is provided on the outer side of the outer buckle plate 21, and a groove is provided in the conduit routing groove 11. When the outer buckle plate 21 is inserted into the conduit routing groove 11, the fixing block 212 engages with the groove to fix the position of the outer buckle plate 21 in the conduit routing groove 11, thereby fixing the position of the outer buckle plate 21 and enabling the placement rack 2 to be stably installed in the conduit routing groove 11.

[0423] Furthermore, in some possible embodiments, the fixing block 212 is configured as an inverted triangular structure with an inclined surface extending outward from bottom to top. The bottom end of the inclined surface is connected to the side of the outer buckle plate 21. When the placement rack 2 is installed, the fixing block 212 will not affect the placement rack 2 from sliding into the conduit routing groove 11. When the placement rack 2 slides in, the fixing block 212 and the conduit routing groove 11 press against the outer buckle plate 21 until the fixing block 212 moves to the position corresponding to the groove. At this time, the outer buckle plate 21 provides an outwardly expanding elastic restoring force, so that the fixing block 212 can smoothly enter the groove. At the same time, the outer side of the outer buckle plate 21 abuts against the groove wall of the conduit routing groove 11 to fix the placement rack 2.

[0424] When using the cleaning component 3 to clean the conduit, to prevent the cleaning component 3 from shifting due to the movement of the conduit, in this embodiment, a cleaning component 3 placement area is formed inside the retainer, specifically configured to place the cleaning component 3. To facilitate the placement of the cleaning component 3, an inlet is provided on one side of the placement area. Through this inlet, the operator can easily place the cleaning component 3 into the placement area. A limiting plate 4 is also provided on the other side of the placement area. The function of the limiting plate 4 is to restrict the position of the cleaning component 3, ensuring that it remains stable during the cleaning process and will not shift due to the movement of the conduit. The limiting plate 4 is located inside the conduit routing groove 11, and a through hole 41b with the same opening direction as the opening of the conduit routing groove 11 is opened at the position corresponding to the opening of the cleaning component 3 to facilitate the insertion of the conduit.

[0425] To secure the cleaning component 3, please refer to Figures 58 and 59. In some possible embodiments, the retainer includes two symmetrically arranged inner snap-fit ​​plates 22c. Each of the two inner snap-fit ​​plates 22c is provided with a limiting block 221 near the slot of the conduit routing groove 11. The limiting block 221 extends from one end of the inner snap-fit ​​plate 22c toward the placement area of ​​the cleaning component 3, and a gap is reserved between the two limiting blocks 221. The inner snap-fit ​​plate 22c can be configured to have an inward elastic force, which can stably clamp the cleaning component 3 when it is inserted into the cleaning component 3 placement area. The design of the outer snap-fit ​​plate 21 and the inner snap-fit ​​plate 22c facilitates the installation and disassembly of the placement rack 2 and the cleaning component 3. Its installation is simple and quick. When maintenance or replacement of the cleaning device is required, the operation can be completed quickly, which greatly reduces the downtime caused by maintenance and helps to improve efficiency. The bottom of the two outer snap-fit ​​plates 21 and the bottom of the two inner snap-fit ​​plates 22c are connected by a base plate. The base plate, the outer snap-fit ​​plates 21 and the inner snap-fit ​​plates 22c are integrally formed. The two inner snap-fit ​​plates 22c are located between the two outer snap-fit ​​plates 21. Its structure is compact and enhances the overall performance of the wire marking tube printer.

[0426] Optionally, referring to Figures 59 and 60, in this embodiment, the cleaning component 3 includes a cleaning cotton 31, which is snapped between two inner snap plates 22c. The cleaning cotton 31 is fixed by clamping it between the two inner snap plates 22c.

[0427] Furthermore, in some embodiments, the opening includes a first cut 311 and several second cuts 312. The direction of the first cut 311 is consistent with the opening direction of the cable routing groove 11. It is formed by cutting the top of the cleaning cotton 31 vertically downwards and is located in the gap between the limiting blocks 221 to facilitate the smooth access of the cable. An open guide groove 313 is provided at the opening end of the first cut 311 to guide the cable to be placed in the first cut 311. Several second cuts 312 are radially distributed with the other end of the first cut 311 as a reference, so that the second cuts 312 have a large accommodating space and can accommodate the insertion and cleaning of cables of different diameters, thereby improving its applicability and flexibility in various application scenarios.

[0428] Please refer to Figure 60. In this embodiment, the cable routing groove 11 is located on the inlet side of the middle shell 1. It is configured to clean the cable tube using the cleaning component 3 when the cable tube enters. A limiting plate 4 is provided on one side of the placement rack 2. The limiting plate 4 is located inside the cable routing groove 11, allowing it to abut against one side of the cleaning component 3. The cable routing groove 11 is located on the inlet side of the middle shell 1. During use, the movement of the cable tube will pull the cleaning component 3 into the middle shell 1. The limiting plate 4 prevents the cleaning component 3 from disengaging from the inner snap-fit ​​plate 22c. Furthermore, the limiting plate 4 has an upward-opening cable passage hole 41b at the position corresponding to the opening. The cable passage hole 41b allows the cable tube to pass through without affecting the printing or cleaning of the cable tube.

[0429] Further, referring to Figure 60, in some embodiments, the limiting plate 4 is provided with a limiting rib 42b on the side opposite to the placement rack 2. The limiting rib 42b is made of a soft material such as rubber, which can prevent the placement rack 2 from shaking after installation and affecting the cleaning effect. At the same time, the limiting rib 42b has a small surface contact with the inner shell 1 to prevent repeated handling from scratching the appearance of the placement rack 2 and affecting its appearance.

[0430] Working principle: During implementation, the cleaning cotton 31 is placed between the two inner snap-fit ​​plates 22c, and the inner snap-fit ​​plates 22c clamp the cleaning cotton 31. Then, the placement frame 2 is placed directly into the conduit routing groove 11, so that the fixing block 212 is snapped into the corresponding groove. At the same time, the outward expansion elasticity of the outer snap-fit ​​plate 21 makes the outer side of the outer snap-fit ​​plate 21 press against the groove wall of the conduit routing groove 11, thereby fixing the placement frame 2. The conduit can be inserted from the opening at the top of the placement frame 2 and the cleaning component 3. When it is necessary to replace the cleaning cotton 31, press the two bracket handles 211 inward respectively, so that the outer snap-fit ​​plate 21 is compressed inward, and the placement frame 2 can be directly removed. Then, the cleaning cotton 31 can be replaced directly.

[0431] This application includes a middle shell 1, a placement rack 2, and a cleaning component 3. The placement rack 2 is configured to hold the cleaning component 3 on the cable routing groove 11 of the middle shell 1. The cleaning component 3 has an opening aligned with the opening direction of the cable routing groove 11, allowing the cable to enter the interior of the cleaning component 3 through the opening. The cleaning component 3 can then tightly wrap around the cable, ensuring that the cable body can contact the cleaning component 3 and be cleaned during the printing process, preventing dirt on the cable body from affecting the printing effect. The outer snap plate 21 is inserted through the provided elastic outer snap part and retainer. When inserted into the cable tray 11, it is squeezed, causing the outer latch plate 21 to retract inward, thereby tightly engaging with the inner wall of the cable tray 11, ensuring the stability of the connection. It is mounted on the inner side of the elastic outer latch, which can maintain and keep the overall structural shape of the placement frame 2 stable. It also allows the elastic outer latch to deform and move relative to the retainer within a certain range, providing the necessary flexibility and adaptability, so that the cleaning part 3 can be stably fixed in the appropriate position, ensuring the smoothness and efficiency of the entire printing process.

[0432] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
