Description

Technical Field

[0001] This application relates to the field of printing technology, and more particularly to a wire marking tube printer. Background Technology

[0002] A marking tube printer is a device that prints markings and other designs onto marking tubes. In related technologies, marking tube printers typically consist of a cover and a main unit. When printing on marking tubes, after placing the marking tube in the marking tube slot of the main unit, the tube needs to be positioned and fixed inside the main unit before the cover can be closed, making the printing process relatively cumbersome. Utility Model Content

[0003] This application provides a wire marking tube printer in which the positioning and fixing of the wire marking tube and the closing operation of the cover are performed simultaneously, which can simplify the printing steps and improve printing efficiency.

[0004] Specifically, a wire marking tube printer includes:

[0005] The host computer has a receiving slot;

[0006] The lid is rotatably connected to the main unit, and the lid is rotatable relative to the main unit about a first axis to open and close the receiving slot;

[0007] The conveyor roller assembly includes a conveyor roller and a floating roller. The conveyor roller is located in the receiving groove and is rotatably connected to the main unit. The floating roller is located in the receiving groove and is disposed opposite to the conveyor roller. A placement channel for placing the wire tube is formed between the floating roller and the conveyor roller. The floating roller is movable relative to the main unit.

[0008] The cover is connected to the floating roller. When the cover rotates toward the host to close the receiving groove, it drives the floating roller to move toward the conveying roller to clamp the wire tube.

[0009] In some embodiments of this application, the cover includes a first cover body and a first drive arm. The first cover body is rotatably connected to the host machine via the first drive arm, and the first cover body is used to open and close the receiving groove. The conveying roller assembly also includes a mounting plate, which is rotatably connected to the host machine. The mounting plate is rotatable relative to the host machine about a second axis, which is parallel to the axis of the conveying roller. The floating roller is disposed on the mounting plate. The first drive arm is connected to a first pressure block, and the mounting plate is drivenly connected to a second pressure block. The second pressure block is rotatably connected to the host machine. When the first cover body rotates toward the host machine to close the receiving groove, the first pressure block drives the second pressure block to rotate, so that the second pressure block drives the mounting plate to rotate, thereby causing the floating roller to move toward the conveying roller.

[0010] In some embodiments of this application, the rotation axis of the second pressure block is parallel to the first axis, and the second pressure block is connected to the mounting plate via a first elastic member. One end of the first elastic member is connected to the mounting plate, and the other end is connected to the second pressure block. The first elastic member is used to reset the floating roller when the cover is closed and the receiving groove is opened.

[0011] In some embodiments of this application, the second pressing block includes: a first pressing part located below the first pressing block and rotatably connected to the main unit; a first driving part connected to the first pressing part and drivingly connected to the mounting plate; wherein, when the first cover rotates toward the main unit to close the receiving groove, the first pressing block presses the first pressing part to make the first pressing part rotate downward, driving the first driving part to rotate upward to drive the mounting plate to rotate, thereby causing the floating roller to move toward the conveying roller.

[0012] In some embodiments of this application, when the first pressing block presses the first pressing part to make the first pressing part rotate, the length of the contact portion between the first pressing block and the first pressing part along the first axial direction is L1, where 5 mm ≤ L1 ≤ 20 mm.

[0013] In some embodiments of this application, the first pressing block has a pressing surface for contacting the first pressing part. The pressing surface includes a first pressing surface and a second pressing surface arranged around the first axial direction, with the first pressing surface and the second pressing surface arranged at an angle. When the first cover rotates toward the host to close the receiving groove, the first pressing surface and the second pressing surface contact the first pressing part in sequence.

[0014] In some embodiments of this application, when the first pressing block presses the first pressing part to make the first pressing part rotate, the first driving part and the first pressing block are arranged at a distance along the first axial direction, and the distance between the first driving part and the first pressing block along the first axial direction is d1, where 2 mm ≤ d1 ≤ 4 mm.

[0015] In some embodiments of this application, the first cover has a maximum opening position on its rotatable trajectory. When the first cover is in the maximum opening position, the distance between the end of the first cover away from the first drive arm and the host is the greatest, the first pressing block is separated from the first pressing part, and when the first cover rotates from the maximum opening position toward the host by a first angle, the first pressing block contacts the first pressing part. The first angle is α, where 30 degrees ≤ α ≤ 75 degrees.

[0016] In some embodiments of this application, the mounting plate is provided with a guide groove that extends along the rotation direction of the mounting plate, and the host is provided with a guide post that cooperates with the guide groove to restrict the mounting plate from rotating about the second axis.

[0017] In some embodiments of this application, the wire marking tube printer further includes: a middle cover located inside the closed cover, the middle cover being rotatably connected to the host, the middle cover being provided with a pressing member for pressing and fixing the wire marking tube, the middle cover being rotatable relative to the host about a third axis, so that the pressing member contacts and separates from the wire marking tube, the third axis being parallel to the first axis; wherein, the closed cover is kinetically connected to the middle cover, when the closed cover rotates toward the host to close the receiving slot, it drives the middle cover to rotate toward the host, so that the pressing member presses and fixes the wire marking tube.

[0018] In some embodiments of this application, the closing cover includes a first cover body and a second drive arm. The first cover body is rotatably connected to the main unit via the second drive arm, and the first cover body is used to open and close the receiving slot. The middle cover includes a second cover body and a rotating arm. The second cover body is rotatably connected to the main unit via the rotating arm, and the pressing component is disposed on the second cover body. The second drive arm is connected to a third pressing block, and a fourth pressing block is rotatably connected to the main unit. The fourth pressing block is drively connected to the rotating arm. When the first cover body rotates toward the main unit to close the receiving slot, the third pressing block drives the fourth pressing block to rotate, so that the fourth pressing block drives the rotating arm and the second cover body to rotate, thereby causing the second cover body to rotate toward the main unit until the pressing component presses and fixes the wire tube.

[0019] In some embodiments of this application, the rotation axis of the fourth pressure block is parallel to the first axis. The fourth pressure block is connected to the rotating arm via a second elastic member. One end of the second elastic member is connected to the fourth pressure block, and the other end is connected to the rotating arm. The second elastic member is used to reset the fourth pressure block when the cover is closed and the receiving groove is opened.

[0020] In some embodiments of this application, the fourth pressing block includes: a second pressing part located to the side of the third pressing block and rotatably connected to the host; a second driving part located above the third pressing block and connected to the second pressing part; wherein, the rotating arm includes a linkage member, the linkage member being kinetically connected to the second driving part, when the first cover rotates toward the host to close the receiving groove, the third pressing block presses the second pressing part to cause the second driving part to rotate upward, thereby driving the second driving part to rotate downward, driving the linkage member to rotate toward the host, and thus causing the second cover to rotate toward the host.

[0021] In some embodiments of this application, the second cover has a maximum separation position on its rotatable trajectory. When the second cover is located at the maximum separation position, the distance between the end of the second cover away from the rotating arm and the host is the greatest. The upper surface of the linkage extends obliquely from the end connected to the second cover in a direction away from the second cover and closer to the host.

[0022] In some embodiments of this application, when the second cover is located at the maximum separation position, the upper surface of the linkage forms a second angle with the horizontal plane, the second angle being β, where 10 degrees ≤ β ≤ 60 degrees.

[0023] In some embodiments of this application, when the third pressing block presses down on the second pressing part to make the second pressing part rotate, the length of the contact portion between the third pressing block and the second pressing part along the first axial direction is L2, where 5 mm ≤ L2 ≤ 20 mm.

[0024] In some embodiments of this application, the wire marking printer further includes a torsion spring connected to the host and the rotating arm. The torsion spring is used to drive the second cover to rotate away from the host when the first cover opens the receiving slot, so as to reset the second cover.

[0025] The beneficial effects of this application are as follows: When printing wire markings using a wire marking printer, the wire markings are first passed through the placement channel. At this time, the receiving slot is in the open state, and the floating roller and the conveying roller are far apart. The width of the placement channel formed between the floating roller and the conveying roller is large, which facilitates the placement of the wire markings. After the wire markings are placed, the cover is rotated towards the host to close the receiving slot. During the rotation of the cover, the floating roller is driven to move towards the conveying roller, which reduces the distance between the floating roller and the conveying roller. When the cover is closed, the floating roller abuts against the wire markings to clamp them, thereby fixing the wire markings in place. Subsequently, the wire markings can be driven to move along the tube feeding direction by rotating the conveying roller. This allows the closing of the receiving slot and the fixing of the wire markings to occur simultaneously, which simplifies the printing steps, improves printing efficiency, and enhances the user experience. After printing, the cover can be rotated away from the host to open the receiving slot. The floating roller can be reset by the reset mechanism to separate the floating roller from the wire markings. Alternatively, the floating roller can be manually moved to separate the floating roller from the wire markings. Attached Figure Description

[0035] 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.

[0036] This application provides a wire marking tube printer to solve the problem in the related technology that, when printing wire marking tubes, after placing the wire marking tube in the wire slot of the host, it is necessary to first position and fix the wire marking tube in the host, and then close the cover before printing can be performed, which is a rather cumbersome printing process.

[0037] Specifically, such as Figure 1 As shown, the wire marking tube printer includes a main unit 10, a cover 20, and a conveyor roller assembly 30; the main unit 10 has a receiving groove 11; the cover 20 is rotatably connected to the main unit 10, and the cover 20 can rotate relative to the main unit 10 about a first axis to open and close the receiving groove 11, the first axis being the extension direction of the rotation center line of the cover 20; the conveyor roller assembly 30 includes a conveying roller 31 and a floating roller 32, the conveying roller 31 is located in the receiving groove 11 and is rotatably connected to the main unit 10, the floating roller 32 is located in the receiving groove 11 and is arranged opposite to the conveying roller 31, a placement channel 33 for placing the wire marking tube 80 is formed between the floating roller 32 and the conveying roller 31, and the floating roller 32 can move relative to the main unit 10.

[0038] The cover 20 is connected to the floating roller 32. When the cover 20 rotates toward the host 10 to close the receiving groove 11, it drives the floating roller 32 to move toward the conveying roller 31 to clamp the wire tube 80.

[0039] Understandably, when printing the wire marking tube 80 using the wire marking tube printer of this application, the wire marking tube 80 is first passed through the placement channel 33. At this time, the receiving slot 11 is in the open state, and the floating roller 32 is far from the conveying roller 31. The width of the placement channel 33 formed between the floating roller 32 and the conveying roller 31 is large to facilitate the placement of the wire marking tube 80. After the wire marking tube 80 is placed, the cover 20 is rotated towards the host 10 to close the receiving slot 11. During the rotation of the cover 20, the floating roller 32 is driven to move towards the conveying roller 31, thereby reducing the distance between the floating roller 32 and the conveying roller 31. When the cover 20 closes the receiving slot, the wire marking tube 80 is placed in the placement channel 33. After the slot 11, the floating roller 32 abuts against the wire tube 80 to clamp the wire tube 80, thereby fixing the wire tube 80 in position. Then, the wire tube 80 can be moved along the tube direction by rotating the conveyor roller 31, so that the closing of the receiving slot 11 and the fixing of the wire tube 80 are carried out simultaneously. This simplifies the printing process, improves printing efficiency, and enhances the user experience. After printing is completed, the cover 20 can be rotated away from the host 10 to open the receiving slot 11. The floating roller 32 can be reset by the reset mechanism to separate the floating roller 32 from the wire tube 80. The floating roller 32 can also be manually moved to separate the floating roller 32 from the wire tube 80.

[0040] like Figures 2 to 4 As shown in some embodiments of this application, the cover 20 includes a first cover body 21 and a first drive arm 22. The first cover body 21 is rotatably connected to the host 10 through the first drive arm 22. The first cover body 21 is used to open and close the receiving groove 11. The first drive arm 22 can be rotatably connected to the host 10 through a first rotating shaft 23. The extension direction of the axis of the first rotating shaft 23 is the first axial direction. The conveying roller assembly 30 also includes a mounting plate 34. The mounting plate 34 is rotatably connected to the host 10. The mounting plate 34 can rotate relative to the host 10 around a second axial direction. The second axial direction is parallel to the axis of the conveying roller 31. The floating roller 32 is disposed on the mounting plate 34. The mounting plate 34 can provide installation space for the floating roller 32, making the installation of the floating roller 32 more convenient. The axis of the conveying roller 31 can be parallel to the thickness direction of the host 10. The second axial direction is the extension direction of the rotation center line of the mounting plate 34. The mounting plate 34 can be rotatably connected to the host 10 through a mounting column. The direction of the axis of the mounting column is the second axial direction.

[0041] The first drive arm 22 is connected to a first pressure block 41, and the mounting plate 34 is driven by a second pressure block 42. The second pressure block 42 is rotatably connected to the main unit 10. When the first cover 21 rotates towards the main unit 10 to close the receiving groove 11, the first pressure block 41 drives the second pressure block 42 to rotate, which in turn drives the mounting plate 34 to rotate, thereby causing the floating roller 32 to move towards the conveying roller 31. It can be understood that the first cover 21 and the mounting plate 34 are connected by a transmission structure formed by the first drive arm 22, the first pressure block 41, and the second pressure block 42. This transmission structure converts the rotation of the first cover 21 into the movement of the floating roller 32, so that when the first cover 21 rotates towards the main unit 10 to close the receiving groove 11, it drives the floating roller 32 to move towards the conveying roller 31.

[0042] In some embodiments, the first drive arm 22 has a first end and a second end. The first end is rotatably connected to the host 10, and the second end is connected to the first cover 21. The first pressure block 41 is disposed at the first end, so that the first pressure block 41 is disposed closer to the host 10, thereby reducing the distance between the first pressure block 41 and the second pressure block 42, making the transmission between the first pressure block 41 and the second pressure block 42 more convenient.

[0043] In some embodiments, the rotation axis of the second pressure block 42 is parallel to the first axis. The second pressure block 42 is connected to the mounting plate 34 via a first elastic member 43. One end of the first elastic member 43 is connected to the mounting plate 34, and the other end is connected to the second pressure block 42. The first elastic member 43 is used to reset the floating roller 32 when the cover 20 opens the receiving groove 11. It can be understood that when the first cover 21 rotates towards the host 10 to close the receiving groove 11, the first pressure block 41 drives the second pressure block 42 to rotate around the rotation axis of the second pressure block 42. When the second pressure block 42 rotates, it drives the mounting plate 34 to rotate along the first direction via the first elastic member 43, thereby driving the floating roller 32 to move towards the conveying roller 31. At this time, the first elastic member 43 is in a stretched or compressed state. After printing is completed, when the first cover 21 is rotated away from the host 10 to open the receiving groove 11, the first pressure block 41 moves with the first rotating arm 52. Rotating the plate 34 releases the restriction on the second pressure block 42, allowing the mounting plate 34 to rotate and reset in the second direction (opposite to the first direction) under the elastic force of the first elastic element 43. This causes the floating roller 32 to move and reset away from the conveying roller 31, thereby separating the floating roller 32 from the wire marking tube 80. This eliminates the need for the user to manually move the floating roller 32 to separate it from the wire marking tube 80, allowing the opening of the receiving groove 11 and the unfixing of the wire marking tube 80 to occur simultaneously. This further simplifies the printing process, improves printing efficiency, and enhances the user experience. The first elastic element 43 can be a tension spring, elastic strip, elastic bellows, or elastic telescopic rod, etc.

[0044] In some embodiments, one end of the first elastic member 43 is connected to the end of the mounting plate 34 away from the mounting post, and the other end is connected to the end of the second pressure block 42 away from the host 10, so that the two ends of the first elastic member 43 can have a greater range of rotation, thereby allowing the mounting plate 34 to have a larger rotation angle when the second pressure block 42 rotates, which in turn increases the range of motion of the floating roller 32.

[0045] like Figure 4 As shown, in some embodiments, the second pressing block 42 includes a first pressing part 421 and a first driving part 422. The first pressing part 421 is located below the first pressing block 41 and is rotatably connected to the host 10. The first driving part 422 is connected to the first pressing part 421 and is drively connected to the mounting plate 34.

[0046] When the first cover 21 rotates towards the host 10 to close the receiving groove 11, the first pressing block 41 presses down on the first pressing part 421, causing the first pressing part 421 to rotate downwards. This drives the first driving part 422 to rotate upwards, thereby driving the mounting plate 34 to rotate, and thus causing the floating roller 32 to move towards the conveyor roller 31. Taking the perspective shown in Figure 4 as an example, when the first cover 21 rotates towards the host 10, the first pressing block 41 rotates downwards, thereby pressing down on the first pressing part 421 and causing the first pressing part 421 to rotate downwards. The first pressing part 421 drives the first driving part 422 to rotate upwards, thereby pulling the mounting plate 34 towards the closing cover 20 through the first elastic element 43, and thus causing the floating roller 32 to move towards the conveyor roller 31.

[0047] In some embodiments, when the first pressing block 41 presses the first pressing part 421 to make the first pressing part 421 rotate, the length of the contact portion between the first pressing block 41 and the first pressing part 421 along the first axial direction is L1, where 5 mm ≤ L1 ≤ 20 mm. It is understandable that when the first pressing block 41 presses against the first pressing part 421, friction will occur at the contact portion between the first pressing block 41 and the first pressing part 421, which will lead to wear on the first pressing block 41 and the first pressing part 421. The longer the length of the contact portion between the first pressing block 41 and the first pressing part 421, the stronger the transmission reliability between the first pressing block 41 and the first pressing part 421, but the friction will also be more intense and the wear will be greater. With prolonged use, the first pressing block 41 and the first pressing part 421 may fail to make contact, resulting in transmission failure. In this embodiment, by designing the length L1 of the contact portion between the first pressing block 41 and the first pressing part 421 to be 5 mm ≤ L1 ≤ 20 mm, the friction between the first pressing block 41 and the first pressing part 421 can be reduced while ensuring the transmission reliability of the first pressing block 41 and the first pressing part 421, thus extending the service life of the first pressing block 41 and the first pressing part 421. L1 can be 5 mm, 10 mm, 15 mm, 20 mm or other values.

[0048] In some embodiments, the first pressing block 41 has a pressing surface for contacting the first pressing part 421. The pressing surface includes a first pressing surface 411 and a second pressing surface 412 arranged around a first axial direction. The first pressing surface 411 and the second pressing surface 412 are arranged at an angle to form an L-shaped pressing surface. When the first cover 21 is rotated toward the host 10 to close the receiving groove 11, the first pressing surface 411 and the second pressing surface 412 contact the first pressing part 421 in sequence. It is understandable that when the pressing surface of the first pressing block 41 contacts the first pressing part 421, the first pressing block 41 and the first pressing part 421 are in surface contact, which can reduce the friction between the first pressing block 41 and the first pressing part 421, thereby extending the service life of the first pressing block 41 and the first pressing part 421. Furthermore, if one of the first pressing surface 411 and the second pressing surface 412 fails due to wear, the other of the first pressing surface 411 and the second pressing surface 412 can also drive the first pressing part 421 to rotate.

[0049] In some embodiments, when the first pressing block 41 presses down on the first abutting part 421 to rotate the first abutting part 421, the first driving part 422 and the first pressing block 41 are arranged at a distance along the first axial direction. The distance between the first driving part 422 and the first pressing block 41 along the first axial direction is d1, where 2 mm ≤ d1 ≤ 4 mm. This ensures that during the rotation of the first pressing block 41 and the first driving part 422, there is always a gap between the first pressing block 41 and the first driving part 422, preventing the first pressing block 41 from contacting the first driving part 422. This avoids friction between the first pressing block 41 and the first driving part 422, which could affect the rotation of the first pressing block 41 and the cover 20. It also prevents the distance between the first pressing block 41 and the first driving part 422 from being too large, which could result in an insufficiently compact structure for the wire marking tube printer. Here, d1 can be 2 mm, 2.5 mm, 3 mm, 4 mm, or other values.

[0050] In some embodiments, the mounting plate 34 is provided with a guide groove 341, which extends along the rotation direction of the mounting plate 34. The main unit 10 is provided with a guide post 35, which cooperates with the guide groove 341 to restrict the mounting plate 34 from rotating around the second axis. When the mounting plate 34 rotates, the guide post 35 slides along the guide groove 341, so that the mounting plate 34 can rotate smoothly according to the preset rotation trajectory, thereby improving the stability and accuracy of the mounting plate 34 during rotation.

[0051] like Figure 5 As shown, in some embodiments, the first cover 21 has a maximum opening position on its rotatable trajectory (e.g., Figure 5When the first cover 21 is in the maximum open position, the distance between the end of the first cover 21 away from the first drive arm 22 and the host 10 is the largest. The first pressing block 41 is separated from the first pressing part 421. When the first cover 21 rotates from the maximum open position to the direction closer to the host 10 by a first angle, the first pressing block 41 contacts the first pressing part 421. It should be noted that the first cover 21 rotates away from the host 10 to open the receiving groove 11, and when the first cover 21 can no longer rotate away from the host 10, the position of the first cover 21 is the maximum opening position. At this time, the receiving groove 11 is opened to the maximum extent, and the first pressing block 41 is separated from the first pressing part 421. During the process of the first cover 21 rotating from the maximum opening position to the direction closer to the host 10 to close the receiving groove 11, the first pressing block 41 rotates from being separated from the first pressing part 421 to contacting the first pressing part 421. When the first pressing block 41 is separated from the first pressing part 421, the rotation of the first cover 21 will not drive the first pressing part 421 to rotate. The mounting plate 34 and the floating roller 32 are in a stationary state, which can prevent the floating roller 32 from moving towards the conveying roller 31 when the first cover 21 starts to rotate and injuring the user's hand.

[0052] The first angle is α, where 30 degrees ≤ α ≤ 75 degrees. When α is less than 30 degrees, the first angle is too small, and the time for the first cover 21 to rotate to contact the first pressing block 41 with the first pressing part 421 is too short, making it easy for the user's hand to be pinched by the floating roller 32. When α is greater than 70 degrees, the first angle is too large, and the time required for the first cover 21 to rotate and close the receiving groove 11 is too long, affecting printing efficiency. α can be 30 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, 70 degrees, 75 degrees, or other angles.

[0053] See 1. Figure 2 and Figure 5 As shown, in some embodiments of this application, the wire marking tube printer also includes a middle cover 50, which is located inside the cover 20 (i.e., the side of the cover 20 closer to the host 10). The middle cover 50 is rotatably connected to the host 10. The middle cover 50 is provided with a pressing member 60 for pressing and fixing the wire marking tube 80. The middle cover 50 can rotate relative to the host 10 about a third axis so that the pressing member 60 can contact and separate from the wire marking tube 80. The third axis is parallel to the first axis. By pressing the pressing member 60, the wire marking tube 80 can move according to a preset tube path, preventing the wire marking tube 80 from tilting up during the printing process.

[0054] The cover 20 and the middle cover 50 are connected by a transmission mechanism. When the cover 20 rotates towards the host 10 to close the receiving slot 11, it drives the middle cover 50 to rotate towards the host 10, so that the pressing component 60 presses down on the fixed wire tube 80. It can be understood that when the cover 20 is rotated to close the receiving slot 11, the middle cover 50 is simultaneously driven to rotate, thus pressing the wire tube 80. This eliminates the need for an additional printing step to close the middle cover 50, further simplifying the printing process, improving printing efficiency, and enhancing the user experience.

[0055] Specifically, such as Figure 2 and Figure 6 As shown, the cover 20 also includes a second drive arm 24. The first cover 21 is rotatably connected to the main unit 10 through the second drive arm 24. The second drive arm 24 can be arranged at intervals with the first drive arm 22 along the first axis. The middle cover 50 includes a second cover 51 and a rotating arm 52. The second cover 51 is rotatably connected to the main unit 10 through the rotating arm 52. The pressing component 60 is disposed on the second cover 51. The rotating arm 52 can be rotatably connected to the main unit 10 through the second rotating shaft 53. The extension direction of the axis of the second rotating shaft 53 is the third axis.

[0056] The second drive arm 24 is connected to a third pressure block 71, and a fourth pressure block 72 is rotatably connected to the main unit 10. The fourth pressure block 72 is drively connected to the rotating arm 52. When the first cover 21 rotates towards the main unit 10 to close the receiving slot 11, the third pressure block 71 drives the fourth pressure block 72 to rotate, so that the fourth pressure block 72 drives the rotating arm 52 and the second cover 51 to rotate, thereby causing the second cover 51 to rotate towards the main unit 10 until the pressing component 60 presses the fixing wire tube 80. It can be understood that the first cover 21 and the second cover 51 are transmitted through the transmission structure formed by the second drive arm 24, the rotating arm 52, the third pressure block 71, and the fourth pressure block 72. This can convert the rotation of the first cover 21 into the rotation of the second cover 51, so that when the first cover 21 rotates towards the main unit 10, it can drive the second cover 51 to rotate towards the main unit 10.

[0057] In some embodiments, the second drive arm 24 has a third end and a fourth end. The third end is rotatably connected to the host 10, and the fourth end is connected to the first cover 21. The third pressure block 71 is disposed at the third end, so that the third pressure block 71 is disposed closer to the host 10, thereby reducing the distance between the third pressure block 71 and the fourth pressure block 72, making the transmission between the third pressure block 71 and the fourth pressure block 72 more convenient.

[0058] In some embodiments, the rotation axis of the fourth pressure block 72 is parallel to the first axis. The fourth pressure block 72 is connected to the rotating arm 52 via a second elastic member 73. One end of the second elastic member 73 is connected to the fourth pressure block 72, and the other end is connected to the rotating arm 52. The second elastic member 73 is used to reset the fourth pressure block 72 when the cover 20 opens the receiving groove 11. Understandably, when the first cover 21 rotates towards the host 10 to close the receiving slot 11, the third pressure block 71 drives the fourth pressure block 72 to rotate around the rotation axis of the fourth pressure block 72. When the fourth pressure block 72 rotates, it drives the rotating arm 52 and the second cover 51 to rotate towards the host 10 through the second elastic element 73. At this time, the first elastic element 43 is in a stretched or compressed state. After printing is completed, when the first cover 21 is rotated away from the host 10 to open the receiving slot 11, the third pressure block 71 rotates and resets with the first rotating arm 52, releasing the restriction on the fourth pressure block 72. This allows the fourth pressure block 72 to rotate downwards and reset under the elastic force of the second elastic element 73, eliminating the need for the user to manually move the fourth pressure block 72 to reset, further simplifying the printing process. The second elastic element 73 can be a tension spring, elastic strip, elastic bellows, or elastic telescopic rod, etc.

[0059] In some embodiments, one end of the second elastic member 73 is connected to the end of the fourth pressure block 72 away from the host 10, and the other end is connected to the end of the rotating arm 52 away from the second cover 51, so that the two ends of the second elastic member 73 can have a greater range of rotation, thereby allowing the second cover 51 to have a larger rotation angle when the fourth pressure block 72 rotates, and thus improving the range of motion of the second cover 51.

[0060] Specifically, the fourth pressing block 72 includes a second pressing part 721 and a second driving part 722. The second pressing part 721 is located on the side of the third pressing block 71 and is rotatably connected to the host 10. The second driving part 722 is located above the third pressing block 71 and is connected to the second pressing part 721.

[0061] The rotating arm 52 includes a linkage 521, which is connected to the second drive unit 722. When the first cover 21 rotates towards the host 10 to close the receiving slot 11, the third pressing block 71 presses the second pressing part 721 to rotate the second drive unit 722, causing it to rotate upwards. This drives the linkage 521 to rotate downwards, thereby causing the second cover 51 to rotate towards the host 10. Taking the perspective shown in Figure 6 as an example, when the first cover 21 rotates towards the host 10, the third pressing block 71 rotates downwards, pressing the second pressing part 721 and causing it to rotate downwards. The second pressing part 721 drives the second drive unit 722 to rotate upwards, thereby pulling the linkage 521 downwards via the second elastic member 73, thus causing the second cover 51 to rotate towards the host 10.

[0062] In some embodiments, when the third pressing block 71 presses down on the second pressing part 721 to cause the second pressing part 721 to rotate, the length of the contact portion between the third pressing block 71 and the second pressing part 721 along the first axial direction is L2, where 5 mm ≤ L2 ≤ 20 mm. This reduces friction between the third pressing block 71 and the second pressing part 721 while ensuring the reliability of the transmission between them, thus extending their service life. L2 can be 5 mm, 10 mm, 15 mm, 20 mm, or other values.

[0063] See also Figure 5 and Figure 6 As shown, in some embodiments, the second cover 51 has a maximum separation position on its rotatable trajectory (e.g., Figure 5 When the second cover 51 is in the maximum separation position, the distance between the end of the second cover 51 away from the rotating arm 52 and the host 10 is the largest. The upper surface of the linkage 521 extends obliquely from the end connected to the second cover 51 in a direction away from the second cover 51 and closer to the host 10.

[0064] It should be noted that when the second cover 51 rotates away from the main unit 10, and the second cover 51 rotates to the point where it can no longer rotate away from the main unit 10, the position of the second cover 51 is the maximum separation position. Figure 6 Taking the perspective shown as an example, the upper surface of the linkage 521 extends downward at this time, so that the linkage 521 can be set downward. This makes it easier for the fourth pressure block 72 to drive the linkage 521 to rotate downward when the first cover 21 rotates towards the host 10, so as to ensure that the fourth pressure block 72 can smoothly pull the middle cover 50.

[0065] When the second cover 51 is in the maximum separation position, the upper surface of the linkage 521 forms a second angle with the horizontal plane, denoted as β, where 10 degrees ≤ β ≤ 60 degrees. This ensures that the tilt angle of the linkage 521 is within a suitable range. When β is less than 10 degrees, the tilt angle of the linkage 521 is too small, and the fourth pressure block 72 will not be able to smoothly drive the linkage 521 to rotate downwards. When β is greater than 60 degrees, the tilt angle of the linkage 521 is too large, which may prevent the fourth pressure block 72 from driving the linkage 521 to rotate downwards. β can be 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, or other degrees.

[0066] In some embodiments, the wire marking tube printer further includes a torsion spring 54, which is connected to the host 10 and the rotating arm 52. The torsion spring 54 drives the second cover 51 to rotate away from the host 10 when the first cover 21 opens the receiving slot 11, thereby resetting the second cover 51. This ensures that after printing, when the first cover 21 is rotated away from the host 10 to open the receiving slot 11, the rotating arm 52 and the second cover 51 can rotate away from the host 10 under the elastic force of the torsion spring 54, thus separating the pressing member 60 from the wire marking tube 80. This eliminates the need for the user to manually move the second cover 51 to separate the pressing member 60 from the wire marking tube 80, further simplifying the printing process. The torsion spring 54 can be sleeved on and connected to the second rotating shaft 53.

[0067] It should also be noted that in other embodiments, the cover 20 and the floating roller 32 can also be driven by other transmission mechanisms, such as a gear and rack mechanism. The cover 20 is rotatably connected to the host 10 through the first rotating shaft 23. The cover 20 is fixed to the first rotating shaft 23, and the first rotating shaft 23 is rotatably connected to the host 10. The axial direction of the first rotating shaft 23 is the first axial direction. A first gear is fixed on the first rotating shaft 23, and the axial direction of the first gear is parallel to the first axial direction. A rack that meshes with the first gear is slidably connected to the host 10. The rack can move relative to the host 10 in the direction of approaching and moving away from the cover 20. The floating roller 32 is mounted on the rack. When the cover 20 rotates in the direction of approaching the host 10, it drives the first gear to rotate. The first gear drives the rack to slide in the direction of approaching the host 10, thereby driving the floating roller 32 to move in the direction of approaching the conveyor roller 31. In other embodiments, the cover 20 and the floating roller 32 can also be driven by a gear transmission mechanism. A first bevel gear is fixed on the first rotating shaft 23, and the axial direction of the first bevel gear is parallel to the first axial direction. A second bevel gear is fixed on the mounting plate 34, and the axial direction of the second bevel gear is parallel to the second axial direction. The second bevel gear meshes with the first bevel gear. When the cover 20 rotates towards the host 10, it drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate, thereby driving the mounting plate 34 to rotate, and then driving the floating roller 32 to move towards the conveying roller 31.

[0068] It should also be noted that in other embodiments, the first cover 21 and the second cover 51 can also be connected by other transmission mechanisms. For example, a second gear can be fixed on the first rotating shaft 23, and a third gear can be fixed on the second rotating shaft 53. The axes of the second gear and the third gear are parallel to the first axis, and the third gear meshes with the second gear. When the first cover 21 rotates, it drives the first rotating shaft 23 and the second gear to rotate, thereby driving the third gear and the second rotating shaft 53 to rotate, and further driving the second cover 51 to rotate. In other embodiments, a pressing rod can also be provided on the inner side of the first cover 21, pressing against the outer side of the second cover 51. When the first cover 21 rotates towards the host 10, the pressing rod pushes the second cover 51 to rotate towards the host 10.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
