[0003] In related technologies, printers need to press against the printable parts when printing to achieve better printing results. However, pressing against the printable parts increases the friction of their movement, thus affecting the smoothness of their movement.

[0004] Application content

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a printer that can solve the problem of increased friction on the object to be printed when it is pressed against it, thereby affecting the smoothness of the movement of the printed object.

[0010] A first pressing block has a first end and a second end. The first end is rotatably connected to the cover plate, and the second end is configured to press against the workpiece to be printed when the cover plate is in the closed state. When the cover plate is in the unfolded state, the second end can swing relative to the cover plate to move closer to and further away from the inlet end.

[0011] When the cover is in the closed state, the first end is located on the side of the second end closer to the inlet end.

[0012] In some embodiments, the first pressing block includes a first body and a first rolling part. The two ends of the first body are respectively formed as a first end and a second end. The first rolling part is rotatably connected to the second end. When the cover plate is in the closed state, the first rolling part is configured to press against the workpiece to be printed, and the material of the first rolling part includes an elastic material.

[0013] In some embodiments, the first end has an abutment block. When the cover is in the unfolded state, the abutment block abuts against the cover and the first pressing block is set at an angle to the cover. The first end is rotatably connected to the cover 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 cover and the second free end is connected to the first pressing block. Under the elastic force of the first torsion spring, the first end has a tendency to move away from the cover.

[0014] In some embodiments, the cover plate includes an upper cover and a middle cover. The upper cover is rotatably connected to the main unit, and the middle cover is rotatably connected to the main unit and located between the main unit and the upper cover. The first pressure block is disposed on the side of the middle cover away from the upper cover. The middle cover is rotatably connected to the main unit via a second rotating shaft. A second torsion spring is sleeved on the second rotating shaft. The first free end of the second torsion spring is connected to the main unit, and the second free end is connected to the middle cover. Under the action of the elastic force of the second torsion spring, the middle cover has a tendency to move closer to the upper cover.

[0015] In some embodiments, the middle cover includes a cover body and a vertical plate. The cover body is rotatably connected to the main unit. The vertical plate protrudes from the inner side of the cover body and has two oppositely arranged mounting holes. One end of the two mounting holes facing each other has an opening. The two ends of the first rotating shaft are respectively inserted into the two mounting holes through the openings. A guide port is formed at the end of the vertical plate away from the cover body. The guide port extends to the opening of the mounting hole, and the distance between its two sidewalls gradually decreases along the direction close to the cover body.

[0016] In some embodiments, the host has a receiving slot, the cover is rotatable relative to the host about a first axis to open and close the receiving slot, and the printer further includes a conveyor roller assembly, the conveyor roller assembly including a transport roller, a floating roller and a mounting plate, the transport roller being located in the printing slot and rotatably connected to the host, the floating roller being located in the printing slot and disposed opposite to the transport roller, forming a placement channel configured to place a workpiece to be printed;

[0017] The mounting plate is rotatably connected to the host machine, the floating roller is disposed on the mounting plate, and the cover plate is drivenly connected to the floating roller. When the cover plate rotates toward the host machine, it drives the floating roller to move toward the conveying roller to clamp the workpiece to be printed.

[0018] In some embodiments, the printer further includes a second pressure block disposed inside the cover plate and spaced apart from the first pressure block. When the cover plate is closed, the second pressure block is configured to press against the workpiece to be printed. The second pressure block includes a second body and a second rolling part, the second rolling part being rotatably connected to the second body. When the cover plate is closed, the second rolling part is configured to press against the workpiece to be printed.

[0019] In some embodiments, the host includes a base and a conveyor mounted on the base. In the conveying direction of the work to be printed, the first distance between the first pressing block and the conveyor is 1cm-7cm, and the second distance between the second pressing block and the conveyor is greater than the first distance. The first pressing block is inclined and its lower end is close to the conveyor, and the second pressing block is vertically arranged to press the work to be printed vertically.

[0020] In some embodiments, the printer further includes a clamping assembly and a printing assembly. The clamping assembly is disposed on the host and located between the first pressure block and the print slot outlet end, and has a first channel through which the part to be printed passes. The printing assembly is disposed on the host and located between the clamping assembly and the outlet end, and has a second channel through which the part to be printed passes. The clamping assembly includes a first clamping member and a second clamping member, which are disposed opposite to each other to form the first channel. The first clamping member is movably connected to the host to change the size of the first channel.

[0021] In some embodiments, the periphery of both the first clamping member and the second clamping member is arc-shaped; the cover plate has a first preset position and a second preset position on its rotatable trajectory. When the cover plate rotates to the first preset position, the first pressure block abuts against the workpiece to be printed. When it rotates to the second preset position, the first clamping member moves relative to the host and clamps the workpiece to be printed.

[0022] In some embodiments, the cover plate has a limiting portion, the first pressing block has a first position, and when the first pressing block is in the first position, the limiting portion abuts against the first pressing block to restrict the first pressing block from rotating toward the cover plate; a limiting groove is formed on the inner side of the cover plate, and when the cover plate abuts against the first pressing block, at least a portion of the second end is received in the limiting groove.

[0023] In some embodiments, when the cover is in the closed state, the first end is located on the side of the second end away from the inlet end; a limiting block is provided on the inner side of the cover, and when the cover is in the closed state, the limiting block abuts against the first pressing block to restrict its rotation toward the printing groove, and the height of the end of the limiting block away from the cover in the vertical direction is higher than that of the second end, and the height difference H between the two satisfies 0≤H≤5mm.

[0024] In some embodiments, a guide post is provided on the side of the pressure tube end of the first pressure block, and a sliding groove corresponding to the guide post is provided on one side of the printing slot of the host. When the first pressure block moves from the disengaged state to the pressure tube state, the guide post can enter the sliding groove and slide along the sliding groove. Before the guide post enters the sliding groove, the first pressure block and the workpiece to be printed remain in a separated state.

[0025] In some embodiments, the first pressure block is provided in at least two sets, corresponding to the inlet and outlet positions of the printing slot, respectively; the printer further includes an elastic element connected to the first pressure block and configured to generate a spring force to drive the first pressure block toward the printing slot when the cover is closed, so that the first pressure block presses the workpiece to be printed.

[0026] In some embodiments, the printer further includes a tube insertion detection device disposed within the printing slot and configured to detect whether the workpiece to be printed has passed through the printing slot. The tube insertion detection device includes at least one of a pressure sensor, a photoelectric sensor, and a microwave sensor.

[0027] In some embodiments, the tube insertion detection device includes a rotating block and an elastic element. The rotating block is rotatably connected to the host computer, and one end of the elastic element is connected to the rotating block and the other end is connected to the host computer. The rotating block is at least partially disposed in the printing slot and can rotate relative to the host computer when the workpiece to be printed passes through it.

[0028] In some embodiments, in the closed state, the distance H between the second end and the rotating block along the extension direction of the printing groove satisfies 0mm≤H≤20mm; the rotating block has a guide surface that smoothly transitions and is positioned toward the inlet end.

[0029] In some embodiments, a first elastic element is provided between the first pressing block and the cover plate, the first elastic element including a torsion spring or an elastic rubber element; a second elastic element is provided between the second pressing block and the cover plate, the second elastic element including a compression spring or an elastic rubber element.

[0030] In some embodiments, the cover plate 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. The first drive arm is connected to a first pressure block, and the mounting plate is driven 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, the first pressure block drives the second pressure block to rotate, thereby causing the floating roller to move toward the conveying roller.

[0031] In some embodiments, the cover plate is provided with a first rotating shaft, and the pressure of the second pressing block on the workpiece to be printed is greater than the pressure of the first pressing block on the workpiece to be printed; both the end of the first pressing block and the end of the second pressing block are provided with a first pressure roller, and the axis of the first pressure roller is parallel to the axis of the first rotating shaft.

[0032] The printer based on the embodiments of this application includes a host, a cover plate, and a first pressure block. The first pressure block has a first end and a second end. The first end is rotatably connected to the cover plate, and the second end is configured to press against the workpiece to be printed when the cover plate is in the closed state. When the cover plate is in the closed state, the first end is located on the side of the second end closer to the inlet end. Thus, under the action of friction, the second end rotates towards the cover plate, thereby reducing the friction between the workpiece to be printed and the first pressure block and improving the smoothness of the workpiece passing through the printing slot.

[0065] 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 embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0066] Example 1

[0067] In existing technology, printers need to press against the printable part when printing to achieve better printing results. However, pressing against the printable part increases the friction of its movement, thus affecting the smoothness of its movement.

[0068] The object to be printed (also known as the printable part) can refer to objects such as wire tubes, leather, metal plates or plastic plates, which need to have labels or patterns printed on their surfaces. In this embodiment of the application, wire tubes are used as the object to be printed for illustrative purposes.

[0069] To solve the above-mentioned technical problems, please refer to Figures 1-3. This application embodiment provides a printout, including a host 100, a cover plate 200 and a first pressing block 300.

[0070] The main unit 100 is the core component of the printer, containing key components such as the print head, ink / toner cartridge, and transmission system. Upon receiving a print command, the print head ejects ink or toner onto the printable material according to a preset pattern or text information, completing the printing task. A print slot 100a is configured for the printable material to pass through. The print 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.

[0071] The cover plate 200 is rotatably connected to the host 100. The cover plate 200 has an unfolded state and a closed state. When the cover plate 200 is in the closed state, it covers the host 100 and can effectively protect the key components such as the print head and transmission system in the printing area, preventing damage from external factors such as dust and moisture. When the cover plate 200 is in the unfolded state, 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.

[0072] The first pressure 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 state, so as to keep it flat and prevent it from moving during printing. Through the pressing action of the first pressure block 300, the relative position between the print head and the workpiece to be printed can be kept stable, thereby improving the print quality.

[0073] In this embodiment of the application, when the first pressing block 300 rotates and the cover plate 200 is in the unfolded state, the second end 302 can swing relative to the cover plate 200 to move closer to and away from the inlet end 100b. When the cover plate 200 is in the closed state, the first end 301 is located on the side of the second end 302 that is closer to the inlet end 100b.

[0074] Described in the orientation shown in Figure X, 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.

[0075] It should be understood that since the second end 302 can swing like the cover plate 200, when the cover plate 200 switches from the unfolded state to the closed state, the user needs to 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 state.

[0076] 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.

[0077] Therefore, in one embodiment of this application, please refer to Figures 3-4. 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.

[0078] 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.

[0079] 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.

[0080] In addition, elastic materials have good shock absorption properties, which can absorb and disperse the vibrations and noise generated during the printing process, reducing interference with the surrounding environment.

[0081] In one embodiment of this application, please refer to FIG5. The first end 301 has an abutment block 301a. When the cover plate 200 is in the unfolded state, the abutment block 301a can abut against the cover plate 200, and the first pressing block 300 is set at an angle to the cover plate 200 to restrict the first pressing block 300 from rotating toward the printing groove 100a.

[0082] When the first pressure block 300 and the cover plate 200 are set at an angle, regardless of whether the cover plate 200 is in the unfolded or closed state, under the action of gravity, the first end 301 of the first pressure block 300 is always located on the side of the second end 302 closer to the inlet end 100b. In this way, when the cover plate 200 rotates from the unfolded state to the closed state, there is no need to manually swing the first pressure block 300. This ensures that when the cover plate 200 is in the closed state, the first end 301 is located on the side of the second end 302 closer to the inlet end 100b, thereby ensuring the smooth flow of the wire pipe. This reduces the user's involvement and improves the efficiency of the cover plate 200 changing from the unfolded state to the closed state.

[0083] 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 4-5, the first end 301 is rotatably connected to the cover plate 200 through the first rotating shaft 303. A first torsion spring 304 is sleeved on the first rotating shaft 303. The first free end of the first torsion spring 304 is connected to the cover plate 200, and the second free end of the first torsion spring 304 is connected to the first pressure block 300. Under the action of the elastic force of the first torsion spring 304, the first end 301 has a tendency to move away from the cover plate 200.

[0084] That is, under the elastic force of the first torsion spring 304, the first pressure block 300 is driven to press against the wire marking tube. Under the elastic force of the first 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.

[0085] In one embodiment of this application, please refer back to Figures 1-2. The cover plate 200 includes an upper cover 210 and a middle cover 220.

[0086] The top 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 top cover 210 is to protect the delicate internal components of the printer from dust, paper scraps and other debris, and at the same time, as an external component of the printer, it provides a clean and safe appearance.

[0087] The middle cover 220 separates the printing area from other parts to prevent debris and other contaminants from polluting the inside of the printer. In addition, 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, and the projection of the middle cover 220 on the upper surface of the host 100 is smaller than that of the upper cover 210 on the upper surface of the host 100. Therefore, in this embodiment, when the cover plate 200 is switched from the unfolded state to the closed state, the first pressure block 300 can be more easily inserted into the printing slot 100a to press against the limit tube.

[0088] Further, referring to Figures 4-5, the middle cover 220 includes a cover body 221 and a vertical plate 222. The cover body 221 is rotatably connected to the main unit 100. The vertical plate 222 protrudes from the inner side of the cover body 221. Two oppositely arranged mounting holes 222a are formed on the vertical plate 222. The two mounting holes 222a have openings at their opposite ends. The two ends of the first rotating shaft 303 are respectively inserted into the two mounting holes 222a through the openings. The first rotating shaft 303 can rotate within the mounting holes 222a. Since the first end 301 of the first pressure block 300 is rotatably connected to the cover plate 200 through the first rotating shaft 303, the first pressure block 300 is driven to rotate relative to the cover body 221 through the rotation of the first rotating shaft 303.

[0089] In one embodiment, referring to FIG5, a guide opening 222b is formed at the end of the upright plate 222 away from the cover 221. The guide opening 222b extends to the opening of the mounting hole 222a. The guide opening 222b has two sidewalls arranged along the length direction of the first rotating shaft 303. The distance between the two sidewalls gradually decreases in the direction close to the cover 221.

[0090] The upright plate 222 and the cover 221 can be connected by integral molding or by fixing with screws, etc. By forming a guide port 222b on the upright plate 222, and the distance between the two side walls of the guide port 222b gradually decreases in the direction close to the cover 221, a funnel-like shape is formed, which can guide the first rotating shaft 303 to enter the mounting hole 222a more easily.

[0091] Furthermore, when the first rotating shaft 303 is inserted into the guide port 222b, it is guided by the two side walls, gradually adjusting its position and smoothly entering the mounting hole 222a. This not only simplifies the installation process but also improves the accuracy and stability of the installation.

[0092] In another embodiment of this application, the middle cover 220 is rotatably connected to the main unit 100 via a second rotating shaft. A second torsion spring is sleeved on the second rotating shaft. The first free end of the second torsion spring is connected to the main unit 100, and the second free end of the second torsion spring is connected to the middle cover 220. Under the action of the elastic force of the second torsion spring, the middle cover 220 has a tendency to move closer to the upper cover 210.

[0093] When the cover plate 200 is in the unfolded state, the middle cover 220, under the elastic force of the second torsion spring, tends to move closer to the upper cover 210. This allows the user to ensure that the middle cover 220 is in the open state when placing the wire tube, without the user having to manually hold the middle cover 220 to keep it open, thus reducing the difficulty of use.

[0094] On the other hand, the second torsion spring not only provides the restoring force, but also provides a certain damping feel during the opening and closing of the middle cover 220. That is, the user can feel a more stable and smooth action when the middle cover 220 is opened and closed, avoiding the impact or noise caused by sudden opening and closing.

[0095] The second rotating shaft can be installed on the middle cover 220 or connected to the host 100, and there is no restriction. In this embodiment, in order to facilitate the assembly of the middle cover 220 and the host 100, the second rotating shaft and the middle cover 220 are an integral structure.

[0096] Please refer to Figure 1. In one embodiment of this application, the printer further includes a tube insertion detection device 400. The tube insertion detection device 400 is disposed in the printing slot 100a and configured to detect whether the workpiece to be printed has passed through the printing slot 100a.

[0097] The tube insertion detection device 400 can detect whether the printable part has entered the print slot 100a. That is, when the printable part is not detected, the tube insertion detection device 400 can transmit a signal to the controller in the host 100, so that the controller can control the host 100 to pause or cancel the printing task, which can reduce printing errors and material waste caused by missing or incorrectly positioned printable parts.

[0098] The presence of the inlet tube detection device 400 can reduce printing errors and improve printing efficiency. Users do not need to worry about printing failures caused by the incorrect placement of the document to be printed, thereby improving the overall user experience.

[0099] The inlet pipe detection device 400 can be a pressure sensor, a photoelectric sensor 410, a microwave sensor, or a combination of any two or three sensors.

[0100] When the pressure sensor is in use, the wire tube contacts the pressure sensor. The pressure sensor converts the pressure signal into an electrical signal and transmits the electrical signal to the controller of the host 100. That is, the pressure sensor can determine whether the printable part has passed through the print slot 100a by detecting the pressure change generated by the printable part on the sensor.

[0101] When the photoelectric sensor 410 is used, it can determine whether the workpiece to be printed has passed through the printing slot 100a by emitting a light beam and detecting reflected light or obstruction. When the workpiece to be printed obstructs the light beam, the light signal received by the receiver will change, thereby triggering the detection circuit to output a corresponding signal.

[0102] When a microwave sensor is used, it can determine whether the workpiece has passed through the printing slot 100a by detecting changes in the frequency of microwaves reflected from it.

[0103] It is understandable that the above three sensors were purchased from commercially available products, so their working principles will not be described further here.

[0104] In one embodiment, referring back to Figure 1 and in conjunction with Figure 6, the tube inlet detection device 400 includes a rotating block 420 and an elastic element 430. The rotating block 420 is rotatably connected to the host 100. One end of the elastic element 430 is connected to the rotating block 420, and the other end of the elastic element 430 is connected to the host 100. The rotating block 420 is at least partially provided so that when the wire tube passes through the tube inlet detection device 400, the rotating block 420 can rotate relative to the host 100.

[0105] In one embodiment of this application, the photoelectric sensor 410 used in the tube insertion detection device 400 is described as an example. When the wire tube has not passed through the tube insertion detection device 400, under the elastic force of the elastic member 430, the rotating block 420 partially blocks the wire bundle emitted by the photoelectric sensor 410. When the wire tube passes through the tube insertion detection device 400, under the pressure, the rotating block 420 will rotate, and the rotating block 420 will not block the wire bundle emitted by the photoelectric sensor 410 at this time. At this time, it can be determined that the wire tube has entered the tube.

[0106] Among them, the elastic element 430 is a tension spring. After the line number tube finishes printing, it is removed from the printing slot 100a and the tension spring returns to its original position. At this time, the rotating block 420 blocks the wire harness emitted by the photoelectric sensor 410, so the host 100 cancels or pauses the printing task, thereby reducing printing errors and material waste caused by missing or incorrectly positioned parts.

[0107] Based on the previous embodiment, when the cover plate 200 is in the closed state, the distance between the second end 302 and the rotating block 420 along the extension direction of the printing groove 100a is H, where H satisfies 0mm≤H≤20mm, and can be 0mm, 5mm, 10mm, 20mm and any two of the above values. When the second end 302 presses against the wire tube, it will apply a certain pressure to the wire tube. Within the above range, the second end 302 can assist the wire tube in driving the rotating block 420 to rotate, so that the tube detection device 400 can more accurately detect the presence of the wire tube, ensuring smooth printing and reducing the probability that the rotating block 420 is difficult to rotate due to the light weight of the wire tube.

[0108] Further, please refer to Figure 1. The rotating block 420 has a guide surface 420a. The guide surface 420a has a smooth transition and is set towards the inlet end 100b. By setting the guide surface 420a, the smooth transition of the guide surface 420a can reduce the resistance and friction encountered by the wire tube when passing through the rotating block 420, and can ensure the smooth flow of the wire tube. The guide surface 420a can be an arc surface or an inclined surface, and no restrictions are imposed here.

[0109] In one embodiment, please continue to refer to Figures 1-2. The printer also includes a second pressing block 500, 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 state, the second pressing block 500 is configured to press against the workpiece to be printed.

[0110] 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 500, 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.

[0111] There can be one or two second pressure blocks 500. When there is only one, the second pressure block 500 can be located on the side of the first pressure block 300 facing the inlet end 100b or on the side of the first pressure block 300 facing the outlet end 100c. The setting can be based on the position of the wire tube.

[0112] There are two second pressure blocks 500. The two second pressure blocks 500 can be located on the side of the first pressure block 300 facing the inlet end 100b and the side of the first pressure block 300 facing the outlet end 100c, respectively. In this way, the wire tube can be effectively pressed down to facilitate the wire tube's passage.

[0113] Furthermore, please refer to Figures 3-4. The second pressing block 500 includes a second body 510 and a second rolling part 520. The second rolling part 520 is rotatably connected to the second body 510. When the cover plate 200 is in the closed state, the second rolling part 520 is configured to press against the workpiece to be printed.

[0114] The axis of the second rolling part 520 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 520 is parallel to the axis of the first rolling part 320. Therefore, the contact between the second rolling part 520 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 520, and the smoothness of the wire tube can also be improved.

[0115] The second rolling part 520 can be made of an elastic material, such as rubber, silicone, or polyurethane, which can better adapt to the uneven surface of the wire tube. By slightly deforming, it ensures that the pressure is evenly distributed across the entire contact surface, thereby reducing print quality problems caused by excessive local pressure. In addition, the elastic material has good shock absorption properties, which can absorb and disperse the vibration and noise generated during the printing process, reducing interference with the surrounding environment.

[0116] Example 2

[0117] As shown in Figure 7, the wire marking tube printer includes a main unit 10, a pressure cap 20, and a conveyor roller assembly 30. The main unit 10 has a receiving groove 11. The pressure cap 20 is rotatably connected to the main unit 10 and can rotate relative to the main unit 10 about a first axis to open and close the receiving groove 11. The first axis is the extension direction of the rotation center line of the pressure cap 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 33c is formed between the floating roller 32 and the conveying roller 31 to place the wire marking tube 80. The floating roller 32 can move relative to the main unit 10.

[0118] The pressure cap 20 is connected to the floating roller 32. When the pressure cap 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.

[0119] 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 33c. At this time, the receiving groove 11 is in the open state, and the floating roller 32 is far from the conveying roller 31. The width of the placement channel 33c 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 pressure cover 20 is rotated towards the host 10 to close the receiving groove 11. During the rotation of the pressure cover 20, the floating roller 32 will be driven to move towards the conveying roller 31, thereby reducing the distance between the floating roller 32 and the conveying roller 31. When the pressure cover 20 is closed, the wire marking tube 80 is placed in the receiving channel 33c. After the receiving slot 11 is closed, 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 conveying 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 pressure 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.

[0120] As shown in Figures 8 to 10, in some embodiments of this application, the pressure cap 20 includes a first cover 21 and a first drive arm 22. The first cover 21 is rotatably connected to the host 10 via the first drive arm 22. The first cover 21 is configured as an opening and closing receiving groove 11. The first drive arm 22 is rotatably connected to the host 10 via 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 axial direction 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 axial direction 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 is rotatably connected to the host 10 via a mounting post. The direction of the axis of the mounting post is the second axial direction.

[0121] 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.

[0122] 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.

[0123] 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 configured to reset the floating roller 32 when the pressure 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 conveyor 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. Rotation resets the second pressure block 42, releasing its restriction. This allows 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, in turn, moves the floating roller 32 away from the conveying roller 31, causing it to separate 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. The opening of the receiving groove 11 and the unfixing of the wire marking tube 80 occur simultaneously, further simplifying the printing process, improving printing efficiency, and enhancing the user experience. The first elastic element 43 can be a tension spring, elastic strip, elastic bellows, or elastic telescopic rod, etc.

[0124] 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.

[0125] As shown in Figure 10, 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.

[0126] 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 causes the first driving part 422 to rotate upwards, driving the mounting plate 34 to rotate, thereby causing the floating roller 32 to move towards the conveying roller 31. Taking the perspective shown in Figure 10 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 pressure cover 20 through the first elastic element 43, thereby causing the floating roller 32 to move towards the conveying roller 31.

[0127] 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.

[0128] In some embodiments, the first pressing block 41 has a pressing surface configured to contact 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.

[0129] 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 pressure 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.

[0130] 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.

[0131] As shown in Figure 11, in some embodiments, the first cover 21 has a maximum opening position on its rotatable trajectory (as shown in Figure 11). When the first cover 21 is in the maximum opening position, the distance between the end of the first cover 21 away from the first drive arm 22 and the host 10 is the greatest, the first pressing block 41 separates from the first pressing part 421, and when the first cover 21 rotates from the maximum opening position toward 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 and the first pressing part 421 are separated. 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 the beginning of separation from the first pressing part 421 to contact with 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.

[0132] 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 from the first cover 21 rotating to the first pressure block 41 contacting 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.

[0133] Referring to Figures 7, 8, and 11, in some embodiments of this application, the wire marking tube printer further includes a middle cover 50, which is located inside the pressure cover 20 (i.e., the side of the pressure cover 20 closer to the host 10). The middle cover 50 is rotatably connected to the host 10. A pressing member 60 configured to press and fix the wire marking tube 80 is provided on the middle cover 50. The middle cover 50 can rotate relative to the host 10 about a third axis so that the pressing member 60 contacts and separates from the wire marking tube 80. The third axis is parallel to the first axis. The pressing of the pressing member 60 allows the wire marking tube 80 to move according to a preset tube path, preventing the wire marking tube 80 from tilting up during printing.

[0134] The pressure cap 20 is connected to the middle cover 50 via a transmission mechanism. When the pressure cap 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 pressure cap 20 is rotated to close the receiving slot 11, the middle cover 50 is simultaneously driven to rotate, thus achieving the clamping of 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.

[0135] As shown in Figures 8 and 12, the pressure 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.

[0136] 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 fixed 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, which 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.

[0137] 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.

[0138] 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 configured to reset the fourth pressure block 72 when the pressure 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.

[0139] 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.

[0140] The fourth pressing block 72 includes a second pressing part 721 and a second driving part 722. The second pressing part 721 is located to the side of the third pressing block 71 and is rotatably connected to the main unit 10. The second driving part 722 is located above the third pressing block 71 and is connected to the second pressing part 721.

[0141] 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 upward and drive the linkage 521 to rotate downward, thereby causing the second cover 51 to rotate towards the host 10. Taking the perspective shown in Figure 12 as an example, when the first cover 21 rotates towards the host 10, the third pressing block 71 rotates downward, thereby pressing the second pressing part 721 and causing it to rotate downward. The second pressing part 721 drives the second drive unit 722 to rotate upward, thereby pulling the linkage 521 downward through the second elastic member 73, thereby causing the second cover 51 to rotate towards the host 10.

[0142] 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.

[0143] Referring again to Figures 11 and 12, in some embodiments, the second cover 51 has a maximum separation position on its rotatable trajectory (as shown in Figure 11). 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 greatest. The upper surface of the linkage 521 extends obliquely from the end that is initially connected to the second cover 51 toward the direction away from the second cover 51 and toward the host 10.

[0144] It should be noted that when the second cover 51 rotates away from the host 10, and the second cover 51 rotates to the point where it can no longer rotate away from the host 10, the position of the second cover 51 is the maximum separation position. Taking the perspective shown in Figure 12 as an example, at this time, the upper surface of the linkage 521 extends downward at an angle, 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.

[0145] 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.

[0146] 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 is configured to drive 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.

[0147] It should also be noted that in other embodiments, the pressure cap 20 and the floating roller 32 can also be driven by other transmission mechanisms, such as a gear and rack mechanism. The pressure cap 20 is rotatably connected to the host 10 through the first rotating shaft 23. The pressure cap 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 pressure cap 20. The floating roller 32 is mounted on the rack. When the pressure cap 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 pressure cap 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 pressure cap 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.

[0148] 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.

[0149] Example 3

[0150] This application provides a printer that can stably fix the workpiece to be printed, preventing it from deviating from a preset position, thereby effectively ensuring the printing effect.

[0151] Please refer to Figure 13, which is a schematic diagram of the structure of a printer carrying a workpiece to be printed provided in an embodiment of this application.

[0152] The printer in this embodiment can be configured in various ways, such as a wire marking tube printer, a label printer, or a barcode printer. Correspondingly, the part to be printed, 3, can be in various forms, such as wire marking tubes, various labels, or barcode paper. Specifically, a wire marking tube printer is a printer configured to print markings, such as numbers, letters, and symbols, on wire marking tubes to identify cables. The following description will use a wire marking tube printer as the printer in this embodiment and a wire marking tube as the part to be printed, 3.

[0153] The printer in this embodiment includes a main unit 1, a cover assembly 2a, and a pressing assembly 4. The main unit 1, as the core foundation and functional platform of the entire printer, may include a base 11 and a printing assembly and a tube feeding assembly mounted on the base 11. The base 11 has a support portion 100 configured to carry the wire marking tubes. The size and shape of the support portion 100 can be determined according to the size and shape of the wire marking tubes, for example, using a groove, slot, or guide rail structure of a specific shape and size. Exemplarily, the support portion 100 is a wire routing groove formed on the base 11. The print head in the printing assembly is the component that prints the marking tube identification information, capable of accurately printing characters, numbers, or symbols on the surface of the wire marking tubes according to preset instructions. The conveyor 12 of the tube feeding assembly is configured to transport the wire marking tubes. In this embodiment, the conveyor 12 is a conveyor roller. The wire marking tubes pass through the wire routing groove on the base 11 and pass through the conveyor roller. The conveyor roller, through rotational motion, gradually transports the wire marking tubes to the corresponding position of the print head to ensure smooth printing operations.

[0154] The cover assembly 2a is connected to the host 1 via a movable connection. The movable connection can be a hinge, slide rail or other structure, which allows the cover assembly 2a to open and close flexibly, facilitating the installation and removal of the wire marking tube and the maintenance of the printer.

[0155] In this embodiment, the pressing component 4 is connected to the cover component 2a and configured to press against the wire tube. Exemplarily, the pressing component 4 and the cover component 2a are elastically connected. When the cover component 2a is closed on the main unit 1, the pressing component 4 presses against the wire tube under elastic force. For example, the pressing component 4 includes at least one pressing block and an elastic connecting component. The pressing block, as the part directly in contact with the wire tube, is made of a material with certain hardness and wear resistance, such as engineering plastic or rubber. The elastic connecting component can be a spring (such as a compression spring or tension spring) or an elastic rubber component, etc., with elastic deformation capability. Taking a compression spring as an example, one end of the compression spring is connected to the pressing block. The connection method can be by providing a connecting post or groove on the pressing block, allowing the compression spring to be sleeved at the connection point or snapped into the groove; the other end of the compression spring is connected to the cover component 2a, and the cover component 2a has a mounting seat at a corresponding position to ensure that the compression spring is stably installed and can effectively transmit elastic force.

[0156] During printing, components such as the print head and transmission mechanism inside the printer experience vibration and mechanical impact. However, due to the elastic connection between the pressing component 4 and the cover component 2a, the pressing component 4 can adaptively adjust the pressing force on the wire tube under the action of elasticity. When vibration or impact is transmitted to the wire tube, the elastic buffer of the compression spring can absorb some of the energy, preventing the wire tube from jumping or displacing due to instantaneous external force. In this way, the printer of this embodiment can always maintain a tight pressing of the pressing block on the wire tube, so that the wire tube is always in a normal working position during the printing process, ensuring that the relative positional accuracy between the print head and the wire tube is within a very small error range. This effectively avoids printing quality problems caused by wire tube jumping, such as clear printed content, no ghosting, and no offset, greatly improving the printing quality of the label.

[0157] Please refer to Figures 14 and 15. Figure 14 is a structural schematic diagram of the cover assembly 2a and the pressing assembly 4 provided in an embodiment of this application; Figure 15 is another structural schematic diagram of the cover assembly 2a and the pressing assembly 4 provided in an embodiment of this application.

[0158] In some embodiments, the pressing component 4 includes a first pressing block 41 and a second pressing block 42, both of which are elastically connected to the cover component 2a. When the cover component 2a is closed on the host 1, the first pressing block 41 and the second pressing block 42 work together to fix the wire tube. The first pressing block 41 and the second pressing block 42 are spaced apart along the conveying direction of the workpiece 3 to be printed, that is, the first pressing block 41 and the second pressing block 42 are spaced apart along the direction of the wire groove. The spacing distance can be determined according to the length and diameter of the wire tube. For example, for a longer wire tube, the spacing distance can be appropriately increased to provide stable pressing at different positions; for a wire tube with a larger diameter or a harder material, the spacing distance can be appropriately decreased to enhance the fixing effect.

[0159] When the cover assembly 2a is in the closed state, at least one of the first pressing block 41 and the second pressing block 42 presses against the wire tube. In some cases, the first pressing block 41 may press against the wire tube alone, for example, when the wire tube is thin, the first pressing block 41, under the action of elasticity, presses the wire tube tightly and fixes it in the cable tray. In other cases, the first pressing block 41 and the second pressing block 42 may press against the wire tube simultaneously, for example, for a thicker wire tube, the first pressing block 41 and the second pressing block 42, under the action of their respective elasticity, apply pressure to the wire tube from different positions, making it more firmly fixed in the cable tray.

[0160] Furthermore, in the conveying direction of the printable part 3, there is a first gap between the first pressure block 41 and the conveyor 12. That is, the first pressure block 41 is located between the conveyor roller and the entrance of the wire guide in the extension direction of the wire guide. After the wire tube enters from the entrance of the wire guide, it first passes through the area where the first pressure block 41 is located, and then enters the conveyor roller. The distance between the first pressure block 41 and the conveyor roller is the first gap, which is set to be no less than 1 cm and no more than 7 cm. This distance range is an optimized value obtained through a large number of experiments and practical applications. For example, when the first gap is 4 cm, in actual operation, after the wire tube enters from the entrance of the wire guide, it will be constrained by the first pressure block 41 4 cm away from the conveyor roller. In this way, when the wire tube is about to be conveyed to the conveyor roller, the presence of the first pressure block 41 can restrict and buffer it to a certain extent, preventing the wire tube from jumping due to the sudden traction force of the conveyor roller when it is conveyed to the conveyor roller.

[0161] The first pressing block 41 is rotatably connected to the cover assembly 2a, for example, via a hinge structure. Furthermore, the first pressing block 41 is inclined in the direction of pressing against the workpiece 3 to be printed, with its lower end positioned closer to the conveyor 12. For example, as the first pressing block gradually moves downwards towards and presses against the wire tube, due to the inclination angle of the first pressing block 41, the wire tube gradually pushes the first pressing block 41 upwards along the inclined surface, causing the first pressing block 41 to rotate.

[0162] A first elastic element 44 is provided between the first pressure block 41 and the cover assembly 2a. The first elastic element 44 includes either a torsion spring or an elastic rubber component. In this embodiment, the first elastic element 44 is a torsion spring. One end of the first elastic element 44 is connected to the first pressure block 41, and the other end is connected to the cover assembly 2a. When the wire tube pushes the first pressure block 41 to rotate, the first elastic element 44 will be twisted and store elastic potential energy. For example, during normal printing, the force exerted by the wire tube on the first pressure block 41 will cause the first elastic element 44 to twist to a suitable angle. The resulting elastic force will be repositioned to press the first pressure block 41 firmly against the wire tube, and can adaptively adjust according to the slight deformation or positional change of the wire tube, always maintaining stable fixation of the wire tube.

[0163] Furthermore, in the conveying direction of the printable part 3, there is a second gap between the second pressure block 42 and the conveyor 12, which is greater than the first gap. That is, in the direction of the extension of the wiring trough, the second pressure block 42 is located between the first pressure block 41 and the entrance of the wiring trough. After entering the printer, the wire tube will first pass through the second pressure block 42 and then through the first pressure block 41. The main function of the second pressure block 42 is to pre-compress the wire tube fed into the printer. When the wire tube first enters the printer, its state may be relatively loose. The second pressure block 42 can apply a certain pressure to the wire tube before it is conveyed to the first pressure block 41, so that the wire tube is initially stabilized. For example, for some wire tubes with softer texture, they may be easily bent or deformed when entering. The pre-compression effect of the second pressure block 42 can keep them in a relatively straight state so that a better clamping effect can be achieved when they reach the first pressure block 41.

[0164] The second pressure block 42 is slidable relative to the cover assembly 2a and is configured to effectively pre-press the wire marking tube. For example, the cover assembly 2a has a groove for accommodating the second pressure block 42, which can move vertically within the groove. The second pressure block 42 is vertically positioned in the direction of pressing the wire marking tube, thus vertically pressing the workpiece 3 to be printed, which facilitates applying stable pressure to the wire marking tube in the vertical direction.

[0165] A second elastic element 45 is provided between the second pressing block 42 and the cover assembly 2a. The second elastic element 45 includes either a compression spring or an elastic rubber element; in this embodiment, the second elastic element 45 is a compression spring. One end of the second elastic element 45 is connected to the second pressing block 42, and the other end is connected to the cover assembly 2a. For example, the second elastic element 45 is pressed against the groove, with one end of the second elastic element 45 abutting against the inner wall of the groove and the other end abutting against the second pressing block 42.

[0166] When the cover assembly 2a is closed, the second pressure block 42 presses against the wire tube under the elastic force of the second elastic member 45. As the size or position of the wire tube changes, the second elastic member 45 will expand and contract accordingly to adjust the pressure of the second pressure block 42. For example, for wire tubes of different diameters, the second elastic member 45 can automatically adjust the compression amount according to its elastic characteristics, so that the second pressure block 42 applies appropriate pressure to achieve effective pre-compression of the wire tube.

[0167] Furthermore, in this embodiment, the first pressure block 41 and the second pressure block 42 can work together to press against wire tubes of different diameters.

[0168] In the vertical direction, the end of the first pressure block 41 is lower than the end of the second pressure block 42. When pressing against a small-diameter wire tube, the first pressure block 41, under the action of the first elastic element 44, can adaptively adjust according to the actual size and shape of the wire tube, closely fitting the surface of the wire tube and applying appropriate pressure. The end of the first pressure block 41 is provided with a first pressure roller 43, which is cylindrical and made of a material with good wear resistance and appropriate hardness. It is usually made of rubber or plastic material covering a metal shaft. Under the action of external force, for example, when the wire tube comes into contact with the first pressure roller 43 during the conveying process and generates friction, the first pressure roller 43 can rotate around its axis. In this way, the sliding friction between the wire tube and the first pressure block 41 is converted into rolling friction, which greatly reduces the friction force and allows the wire tube to move smoothly under the first pressure block 41. This effectively avoids the problem of wire tube conveying jamming caused by excessive friction, making the wire tube conveying smoother.

[0169] The second pressure block 42 is vertically positioned so that its end is higher than the end of the first pressure block 41. When pressing against a large-diameter wire tube, the larger diameter of the wire tube will first contact the lower end of the first pressure block 41. Under the action of the first elastic element 44, the first pressure block 41 adjusts its position according to the large-diameter wire tube and applies a small pressure to initially fix it. At this time, the second pressure block 42, under the action of the second elastic element 45, contacts the large-diameter wire tube and applies a larger pressure. The first and second pressure blocks 41 work together to stably press the large-diameter wire tube from different positions, ensuring that the large-diameter wire tube will not shift or jump during printing. The end of the second pressure block 42 is also equipped with a first pressure roller 43, which operates on the same principle as the first pressure roller 43 on the first pressure block 41.

[0170] In this embodiment, the pressure assembly 4 can automatically adjust the fixing method according to the diameter of the wire tube. When printing small-diameter wire tubes, since the end of the first pressure block 41 is lower, it will preferentially contact the wire tube and achieve adaptive fixing under the action of the first elastic member 44, providing appropriate pressure for the small-diameter wire tube and avoiding damage to the wire tube due to excessive pressure. This ensures the stability of the small-diameter wire tube during the printing process, thereby guaranteeing print quality. For large-diameter wire tubes, they first contact the first pressure block 41 with a lower end and are initially fixed with a smaller pressure. Subsequently, the second pressure block 42 also participates in the cooperative fixing and applies a larger pressure. The above-mentioned dual fixing mechanism can effectively fix the large-diameter wire tube, keeping it in a precise position during the printing process and avoiding displacement or jumping, thereby guaranteeing print quality.

[0171] Please refer to Figures 12 and 16. Figure 16 is a schematic diagram of the structure of the printer provided in an embodiment of this application.

[0172] To further improve the pressure effect on the wire tube, this embodiment also includes a cap assembly 222c. The cap assembly 2a includes a first movable cap 21a and a second movable cap 22a. The first movable cap 21a is located between the base 11 and the second movable cap 22a, and is connected to the base 11 via a rotatable connection. Exemplarily, the first movable cap 21a includes a first cap body 211 and a rotating arm 212. One end of the first cap body 211 is connected to the rotating arm 212, which is rotatably connected to the base 11. The rotatable connection uses a suitable pin or hinge structure to ensure the stability and flexibility of the first movable cap 21a during opening and closing. The other end of the first cap body is connected to a pressure assembly 4. When the first movable cap 21a rotates to close, the pressure assembly 4 can vertically press against the wire tube from above, ensuring the wire tube is stably placed in the wiring groove of the base 11.

[0173] The second movable cover 22a includes a second cover body 221c and a cover assembly 222c. The second cover body 221c is rotatably connected to the base 11. The rotatable connection adopts a suitable pin or hinge structure to ensure the stability and flexibility of the second movable cover 22a during the opening and closing process, which facilitates operation by the operator and maintenance of the printer's internal parts.

[0174] The cap assembly 222c is connected to the side of the second cover 221c facing the first movable cover 21a. When the cover assembly 2a is fully closed, the cap assembly 222c will apply additional pressure to the first movable cover 21a, making the pressure assembly 4 on the first movable cover 21a press the wire tube more tightly.

[0175] Furthermore, the cap assembly 222c includes at least one second pressure roller 2221 configured to press against the first movable cap 21a. The second pressure roller 2221 is made of a material with good wear resistance and appropriate hardness, such as rubber or plastic, so that the second pressure roller 2221 undergoes slight deformation when in contact with the first movable cap 21a, thus applying more uniform pressure to the first movable cap 21a. When two second pressure rollers 2221 are provided, they are spaced apart. This spaced arrangement allows the first movable cap 21a to receive more uniform pressure, avoiding problems such as deformation of the first movable cap 21a or insecure fixing of the wire tube due to excessive or insufficient local pressure. For example, the two second pressure rollers 2221 are located at both ends or key stress points of the first movable cover 21a. When the second movable cover 22a is closed, the two second pressure rollers 2221 apply pressure to the first movable cover 21a at the same time, so that the pressure-receiving component 4 on the first movable cover 21a can evenly transmit the pressure to the wire tube, ensuring that the wire tube can be tightly fixed in the entire length direction, thereby ensuring good printing quality.

[0176] As shown in Figure 14, in some embodiments, the first movable cover 21a has a through hole 2111 through which a portion of the second pressing block 42 can pass. The position of the through hole 2111 is determined according to the movement trajectory of the second pressing block 42 during the closing process of the second movable cover 22a, ensuring that the second pressing block 42 can accurately pass through the through hole 2111 when the cover is closed. The shape of the through hole 2111 is adapted to the outer contour of the portion of the second pressing block 42 that protrudes through it, for example, it can be circular, rectangular or other shapes, ensuring that the second pressing block 42 can pass through smoothly.

[0177] When the cover assembly 2a is in the closed state, there is a third gap between the first movable cover 21a and the second movable cover 22a. The third gap is specifically configured to avoid obstructing the portion of the through hole 2111 of the second pressure block 42. Due to the existence of the third gap, the portion of the second pressure block 42 protruding from the through hole 2111 will not come into contact with or collide with the first movable cover 21a, thus avoiding affecting the closed state of the first movable cover 21a, ensuring a stable printing environment, and thereby guaranteeing print quality.

[0178] Example 4

[0179] Please refer to Figures 17-19. This application embodiment provides a printed component, including a host 100, a cover plate 200, and a first pressing block 300.

[0180] The main unit 100 is the core component of the printer, containing key components such as the print head, ink / toner cartridge, and transmission system. Upon receiving a print command, the print head ejects ink or toner onto the printable material according to a preset pattern or text information, completing the printing task. The main unit 100 has a print slot 100a configured for the printable material to pass through. The print 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.

[0181] The cover plate 200 is rotatably connected to the host 100. The cover plate 200 has an unfolded state and a closed state. When the cover plate 200 is in the closed state, it covers the host 100 and can effectively protect the key components such as the print head and transmission system in the printing area, preventing damage from external factors such as dust and moisture. When the cover plate 200 is in the unfolded state, 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.

[0182] The first pressure 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 state, so as to keep it flat and prevent it from moving during printing. Through the action of the first pressure block 300, the relative position between the print head and the workpiece to be printed can be kept stable, thereby improving the print quality.

[0183] The cover plate 200 has a limiting part 201, and the first pressing block 300 has a first position on the rotation trajectory. When the first pressing block 300 rotates to the first position, the limiting part 201 abuts against the first pressing block 300, and the limiting part 201 restricts the first pressing block 300 from rotating toward the cover plate 200. In this way, it is difficult for the user to continue to rotate toward the cover plate 200 under the restriction of the limiting part 201, and it is also difficult to break the first pressing block 300, thereby reducing the probability of the first pressing block 300 breaking.

[0184] Please refer to Figures 19-20. In one embodiment, a limiting portion 201 is formed on the inner side of the cover plate 200, which can maximize the use of the printer's internal space, avoid additional external structures or components, and make the overall structure of the printer more compact.

[0185] A limiting part 201 is formed on the inner side of the cover plate 200. There is no need to install the limiting part 201 separately. It is only necessary to ensure the correct alignment and connection between the cover plate 200 and the main unit 100, which simplifies the assembly process. The cover plate 200 has a limiting effect on the first pressure block 300, thereby reducing the probability of the first pressure block 300 breaking.

[0186] Furthermore, a limiting groove 200a is provided on the inner side of the cover plate 200. When the cover plate 200 abuts against the first pressing block 300, the second end 302 can be partially contained in the limiting groove 200a, or the second end 302 can be completely contained in the limiting groove 200a. In this way, the second end 302 can abut against the cover plate 200, making it difficult to continue to pry the first pressing block 300 towards the cover plate 200, thus reducing the risk of manually breaking the first pressing block 300.

[0187] The limiting groove 200a can be formed by the cover plate 200 and the ribs on the inner side of the cover plate 200. The inner side of the cover plate 200 forms the bottom of the limiting groove 200a. The ribs and the cover plate 200 can be integrally formed, thereby increasing the structural strength of the entire cover plate 200.

[0188] In another embodiment, when the first pressing block 300 is in the first position, the cover plate 200 has a first projection on the host 100 along the thickness direction of the cover plate 200, and the first pressing block 300 has a second projection on the host 100, the second projection being located within the outer contour of the first projection.

[0189] That is, when the first pressing block 300 rotates to the first position during its rotation trajectory, the second end 302 of the first pressing block 300 will abut against the cover plate 200. In other words, the first pressing block 300 is unlikely to contact the edge of the cover plate 200, making it difficult to achieve stress concentration, thereby further reducing the probability of the first pressing block 300 being broken by human intervention.

[0190] It is understandable that, since the first end 301 of the first pressure block 300 is rotatably connected to the cover plate 200, when the cover plate 200 is in the unfolded state, the second end 302 can swing relative to the cover plate 200. By manually swinging the first pressure block 300, the second end 302 can be moved closer to or further away from the inlet end 100b.

[0191] In this embodiment of the application, the second end 302 of the first pressing block 300 is defined to have a first side and a second side facing away from each other. Since the first end 301 of the first pressing block 300 is rotatably connected to the cover plate 200, when the first pressing block 300 is in the first position, the second end 302 can rotate to the first side to abut against the cover plate 200, or the second end 302 can rotate in the opposite direction to the second side to abut against the cover plate 200.

[0192] When the first side of the second end 302 abuts against the cover plate 200, the first end 301 is located on the side of the second end 302 closer to the inlet end 100b. When the workpiece to be printed is a wire tube, the wire tube enters from the inlet end 100b and exits from the outlet end 100c under the action of the conveying component. Therefore, in order to reduce the friction between the second end 302 and the wire tube, when the cover plate 200 is in the closed state, the first end 301 is located on the side of the second end 302 closer to the inlet end 100b. That is, during the movement of the wire tube, under the action of friction, the second end 302 rotates towards the cover plate 200 under the pushing action of the wire tube, and will not further squeeze the wire tube, thus ensuring the smooth flow of the wire tube.

[0193] Based on the previous embodiment, please refer to FIG21. The first end 301 has an abutment block 301a, and the first pressing block 300 has a second position. When the first pressing block 300 is in the second position, the abutment block 301a abuts against the cover plate 200 to restrict the first pressing block 300 from rotating toward the printing groove 100a, and the first pressing block 300 and the cover plate 200 are set at an angle.

[0194] When the first pressure block 300 and the cover plate 200 are set at an angle, regardless of whether the cover plate 200 is in the unfolded or closed state, the first end 301 of the first pressure block 300 is always located on the side of the second end 302 closer to the inlet end 100b. In this way, when the cover plate 200 rotates from the unfolded state to the closed state, there is no need to manually swing the first pressure block 300. This ensures that when the cover plate 200 is in the closed state, the first end 301 is located on the side of the second end 302 closer to the inlet end 100b, thereby ensuring the smooth flow of the wire pipe.

[0195] 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 Figure 22, the first end 301 is rotatably connected to the cover plate 200 through a rotating shaft. A torsion spring 303 is sleeved on the rotating shaft. The first free end of the torsion spring 303 is connected to the cover plate 200, and the second free end of the torsion spring 303 is connected to the first pressure block 300. Under the action of the elastic force of the torsion spring 303, the first end 301 has a tendency to move away from the cover plate 200.

[0196] Under the elastic force of the torsion spring 303, the first pressure block 300 is driven to press against the wire marking tube. Under the elastic force of the torsion spring 303 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.

[0197] In another embodiment, when the first pressure block 300 is in the first position, the second side of the second end 302 abuts against the cover plate 200. In this embodiment, the first end 301 is located on the side of the second end 302 away from the inlet end 100b, so that the first pressure block 300 can also press against the wire tube under its own weight.

[0198] It should be understood that, since the wire marking tube enters from the inlet end 100b and exits from the outlet end 100c under the action of the conveying component, when the cover plate 200 is in the closed state, the friction of the wire marking tube will drive the second end 302 to move towards the outlet end 100c. During this stage, since the cover plate 200 is in the closed state, the second end 302 will squeeze the wire marking tube, which may easily cause the first pressure block 300 to break or affect the smoothness of the wire marking tube.

[0199] Therefore, in this embodiment of the application, a limiting block (not shown in the figure) is provided on the inner side of the cover plate 200. When the cover plate 200 is in the closed state, the limiting block abuts against the first pressing block 300 to restrict the first pressing block 300 from rotating toward the printing groove 100a.

[0200] Thus, under the action of friction, the first pressing block 300 will come into contact with the limiting block, and the limiting block will restrict the first pressing block 300 from rotating toward the printing groove 100a, that is, restrict the second end 302 from moving toward the outlet end 100c, thereby reducing the probability of the first pressing block 300 breaking and not affecting the smoothness of the wire tube.

[0201] During the movement of the wire tube, a continuous frictional force is applied to the first pressing block 300. If the frictional force is too great, when the first pressing block 300 moves to its limit position, that is, when the first pressing block 300 contacts the limiting block, the first pressing block 300 may still be broken if the limiting block is too short.

[0202] Therefore, in one embodiment of this application, when the cover plate 200 is in the closed state, the height of the end of the limiting block away from the cover plate 200 in the vertical direction is higher than the height of the second end 302 in the vertical direction, and the height difference between the two is H, where H satisfies 0≤H≤5mm, and H can be a range of 0mm, 1mm, 2mm, 3mm, 4mm, 5mm or any two of them.

[0203] The first pressing block 300 and the limiting block form a lever structure. The connection between the first pressing block 300 and the end of the limiting block away from the cover plate 200 forms a rotation point. When the height difference H between the two is within the above range, the length of the limiting block is sufficient, that is, the length of the first pressing block 300 protruding from the limiting block is short, that is, the torque is short. Therefore, the first pressing block 300 is difficult to break when subjected to friction.

[0204] 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.

[0205] Therefore, in one embodiment of this application, please refer to FIG20, 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.

[0206] 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.

[0207] 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.

[0208] In addition, elastic materials have good shock absorption properties, which can absorb and disperse the vibrations and noise generated during the printing process, reducing interference with the surrounding environment.

[0209] In one embodiment, referring to FIG20, the printer further includes a second pressure block 400, which is spaced apart from the first pressure block 300. When the cover plate 200 is closed, the second pressure block 400 is configured to press against the workpiece to be printed.

[0210] 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 400, 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.

[0211] There can be one or two second pressure blocks 400. When there is only one, the second pressure block 400 can be located on the side of the first pressure block 300 facing the inlet end 100b or on the side of the first pressure block 300 facing the outlet end 100c. The setting can be based on the position of the wire tube.

[0212] There are two second pressure blocks 400. The two second pressure blocks 400 can be located on the side of the first pressure block 300 facing the inlet end 100b and the side of the first pressure block 300 facing the outlet end 100c, respectively. In this way, the wire tube can be effectively pressed down to facilitate the wire tube's passage.

[0213] Furthermore, please continue to refer to Figure 20. The second pressing block 400 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.

[0214] 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.

[0215] 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. In addition, the elastic material has good shock absorption properties, which can absorb and disperse the vibration and noise generated during the printing process, reducing interference with the surrounding environment.

[0216] In one embodiment of this application, please refer back to Figures 17 and 18. The cover plate 200 includes an upper cover 210 and a middle cover 220.

[0217] The top 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 top cover 210 is to protect the delicate internal components of the printer from dust, paper scraps and other debris, and at the same time, as an external component of the printer, it provides a clean and safe appearance.

[0218] The middle cover 220 is located inside the upper cover 210, and its rotation range is smaller than that of the upper cover 210. The middle cover 220 also has a closed state. When both the middle cover 220 and the upper cover 210 are in the closed state, the projection of the middle cover 220 on the upper surface of the printer falls into the projection of the upper cover 210 on the upper surface of the printer in the vertical direction. Therefore, in this embodiment, the first pressing block 300 and the limiting part 201 are both provided on the side of the middle cover 220 away from the upper cover 210. In this way, the first pressing block 300 can be more easily inserted into the printing slot 100a to press the limit tube.

[0219] Example 5

[0220] Please refer to Figure 23. This application proposes a wire marking tube printer 1, which includes a host 10, a pressure cap 20, a pressure block assembly 30, a clamping assembly 40, and a printing assembly 50.

[0221] The main unit 10 has a tube-laying groove 11a configured to accommodate the wire tube 2. The two opposite ends of the tube-laying groove 11a form an inlet 12d and an outlet 13. The wire tube 2 extends into the tube-laying groove 11a through the inlet 12d and leaves the tube-laying groove 11a through the outlet 13. The pressure cap 20 is connected to the main unit 10. The pressure block assembly 30 is disposed inside the pressure cap 20 and located between the inlet 12d and the outlet 13. The pressure block assembly 30 is configured to abut against the wire tube 2 so that the wire tube 2 contacts the bottom wall of the tube-laying groove 11a. That is, after the pressure block assembly 30 abuts against the wire tube 2, the pressure block assembly 30 can press the wire tube 2 onto the bottom wall of the tube-laying groove 11a, thereby preventing the wire tube 2 from moving up and down in the tube-laying groove 11a.

[0222] The pressure cap 20 is rotatably connected to the main unit 10. The pressure cap 20 can drive the pressure block assembly 30 to rotate together, so that the pressure block assembly 30 can abut or separate from the wire tube 2. Alternatively, the pressure cap 20 is detachably connected to the main unit 10. After the wire tube 2 extends into the tube release groove 11a from the inlet 12d, the pressure cap 20 is placed on the main unit 10, so that the pressure block assembly 30 is placed on the main unit 10 along with the pressure cap 20, so that the pressure block assembly 30 abuts or separates from the wire tube 2.

[0223] Both the clamping assembly 40 and the printing assembly 50 are located on the host 10. The clamping assembly 40 is located between the pressure block assembly 30 and the outlet 13, and the printing assembly 50 is located between the clamping assembly 40 and the outlet 13. The clamping assembly 40 has a first channel (not shown in the figure) configured for the wire number tube 2 to pass through, and the clamping assembly 40 is configured to clamp the wire number tube 2. The printing assembly 50 has a second channel (not shown in the figure) configured for the wire number tube 2 to pass through, and the printing assembly 50 is configured to print on the wire number tube 2.

[0224] The wire marking tube 2 extends from the inlet 12d into the outlet 11a, and passes sequentially through the pressure block assembly 30, the first channel, and the second channel before extending out from the outlet 13. The main unit 10 provides installation space and a base for the clamping assembly 40 and the printing assembly 50. The clamping assembly 40 can be configured not only to clamp the wire marking tube 2, but also to transport the wire marking tube 2, allowing it to move and print within the wire marking tube printer 1. The printing assembly 50 can be configured to print characters on the outer wall of the wire marking tube 2.

[0225] It should be noted that in this embodiment, a pressure block assembly 30 is provided between the inlet 12d and the pressure assembly, so that the pressure block assembly 30 and the pressure assembly can jointly limit the wire tube 2. The pressure block assembly 30 first presses the wire tube 2 against the bottom wall of the tube release groove 11a, and then the pressure of the pressure assembly further limits the position of the wire tube 2. At this time, the position of the wire tube 2 is more stable after multiple limits. Finally, the printing assembly 50 performs the printing operation on the wire tube 2, reducing the vertical movement of the wire tube 2 during printing, thereby improving the final printing effect of the wire tube 2.

[0226] In some embodiments, as shown in FIG23, the host 10 includes a base 14 and a main cover 15. The main cover 15 is rotatably connected to the base 14. A pressure cap 20 is located between the base 14 and the main cover 15. The main cover 15 and the base 14 together can form a closed receiving cavity. The pressure cap 20, the pressure block assembly 30, the clamping assembly 40, and the printing assembly 50 are all located in the receiving cavity. The pressure cap 20 and the main cover 15 can be rotatably connected to the base 14 through different pivots. The pressure cap 20 can be fixed to the inner side of the main cover 15 so that the pressure cap 20 and the main cover 15 can be closed synchronously. Alternatively, the pressure cap 20 can be separately set from the main cover 15 so that the pressure cap 20 and the main cover 15 can be closed independently. For example, after closing the pressure cap 20, the flow of the wire tube 2 in the host 10 can be observed. Finally, the main cover 15 is closed. The above schemes can be set according to the actual situation, and this embodiment does not limit them.

[0227] Please refer to Figure 24. In some embodiments of this application, the pressure cap 20 is provided with a first rotating shaft 21. The pressure cap 20 is rotatably connected to the host 10 through the first rotating shaft 21. The pressure block assembly 30 is disposed inside the pressure cap 20. During the rotation of the pressure cap 20, it can drive the pressure block assembly 30 to move together, thereby realizing the contact and separation of the pressure block assembly 30 and the wire tube 2. The rotatable trajectory of the pressure cap 20 has a closed position, which is shown in Figure 25 as the pressure cap 20 being in the closed position. When the pressure cap 20 rotates towards the host 10 to the closed position, the pressure cap 20 closes to the host 10, and the pressure block assembly 30 abuts against the wire tube 2.

[0228] In some embodiments, when the cap 20 is rotated to the closed position, the pressure block assembly 30 abuts against the upper part of the wire tube 2 to limit the wire tube 2 in the vertical direction; the clamping assembly 40 abuts against the side of the wire tube 2 to limit the wire tube 2 in the horizontal direction.

[0229] It is understandable that the limiting direction of the pressure block assembly 30 on the wire tube 2 is perpendicular to the limiting direction of the clamping assembly 40 on the wire tube 2. The wire tube 2 passes through the pressure block assembly 30 first, so the pressure block assembly 30 will first press the wire tube 2 against the bottom wall of the tube placement groove 11a to prevent the wire tube 2 from moving vertically. Then the wire tube 2 passes through the first channel of the clamping assembly 40, and the clamping assembly 40 clamps the side of the wire tube 2 to prevent the wire tube 2 from moving horizontally. Finally, the wire tube 2 can stably enter the second channel of the printing assembly 50. Since the moving position of the wire tube 2 is stable, the wire tube printer 1 in this embodiment can achieve a better printing effect.

[0230] It should be noted that when the wire marking tube printer 1 prints on the wire marking tube 2, the pressure block assembly 30 limits the wire marking tube 2 in the vertical direction. At this time, the wire marking tube 2 undergoes a certain amount of deformation in the vertical direction. After leaving the pressure block assembly 30, the wire marking tube 2 enters the first channel of the clamping assembly 40. The clamping assembly 40 limits the wire marking tube 2 in the horizontal direction. Therefore, the clamping assembly 40 can restore the deformation of the wire marking tube 2 caused by the pressure block assembly 30, thereby reducing the adverse effect of deformation on the printing of the wire marking tube 2.

[0231] Furthermore, as shown in Figure 23, when the pressure cap 20 is rotated to the closed position, the pressure block assembly 30 and the clamping assembly 40 are spaced apart along the extension direction of the tube placement groove 11a, that is, there is a gap between the pressure block assembly 30 and the clamping assembly 40. The wire tube 2 is first pressed by the pressure block assembly 30. The wire tube 2 undergoes vertical deformation at the position where it abuts against the pressure block assembly 30. Then the wire tube 2 moves from the pressure block assembly 30 to the clamping assembly 40. After the wire tube 2 leaves the pressure block assembly 30, the shape of the wire tube 2 is initially restored at the gap between the pressure block assembly 30 and the clamping assembly 40. Then the wire tube 2 enters the clamping assembly 40 again. The clamping assembly 40 can assist the wire tube 2 to further restore its deformation.

[0232] The distance between the pressure block assembly 30 and the clamping assembly 40 along the extension direction of the tube placement groove 11a is d1 (not shown in the figure). d1 satisfies 1cm≤d1≤5cm. When printing the wire tube 2, if the distance d1 between the pressure block assembly 30 and the clamping assembly 40 is too small, the vertical deformation of the wire tube 2 at the pressure block assembly 30 cannot be effectively recovered at the clamping assembly 40. If the distance d1 between the pressure block assembly 30 and the clamping assembly 40 is too large, the wire tube 2 will move a long distance between the pressure block assembly 30 and the clamping assembly 40 after passing the pressure block assembly 30. This will not be able to ensure that the wire tube 2 is always in contact with the bottom wall of the tube placement groove 11a in the vertical direction, which may cause the wire tube 2 to tilt upward after moving between the pressure block assembly 30 and the clamping assembly 40.

[0233] Please refer to Figure 23. In some embodiments of this application, the clamping assembly 40 includes a first clamping member 41a and a second clamping member 42a. The first clamping member 41a and the second clamping member 42a are disposed opposite to each other, forming a first channel between them. The first channel is located between the first clamping member 41a and the second clamping member 42a, and the wire tube 2 passes through the first channel. Both the first clamping member 41a and the second clamping member 42a can provide a limiting function for the wire tube 2. The first clamping member 41a and / or the second clamping member 42a can be rotatably connected to the host 10. Since the wire tube 2 contacts the clamping assembly 40 when passing through the first channel, there is friction between the clamping assembly 40 and the wire tube 2 during the rotation of the first clamping member 41a and / or the second clamping member 42a. Therefore, the friction can drive the wire tube 2 to move in the tube placement groove 11a.

[0234] The first clamping member 41a is movably connected to the host 10 so that the first clamping member 41a can move relative to the host 10 and change the size of the first channel. That is, when the wire tube 2 passes through the first channel, the first clamping member 41a can move towards the second clamping member 42a so that the range of the first channel is reduced, that is, the wire tube 2 is clamped in the first channel, thereby increasing the friction between the clamping assembly 40 and the wire tube 2, so that the clamping assembly 40 can drive the wire tube 2 to move more smoothly.

[0235] The first clamping member 41a and the second clamping member 42a are both arc-shaped. When the wire tube 2 is clamped between the first clamping member 41a and the second clamping member 42a, the arc-shaped surface on the clamping member contacts the wire tube 2, which can reduce the friction between the wire tube 2 and the clamping assembly 40, thereby reducing the wear of the clamping assembly 40 on the wire tube 2 and making the movement of the wire tube 2 smoother.

[0236] Furthermore, in some embodiments of this application, the rotatable trajectory of the pressure cap 20 has a first preset position and a second preset position. When the pressure cap 20 rotates towards the host 10 to the first preset position, the pressure block assembly 30 abuts against the wire tube 2. When the pressure cap 20 continues to rotate towards the host 10 to the second preset position, the first clamping member 41a moves relative to the host 10 and clamps the wire tube 2. It can be understood that during the rotation and closing process of the pressure cap 20, the pressure block assembly 30 first abuts against the wire tube 2, and then the clamping assembly 40 clamps the wire tube 2. That is, the contact between the pressure block assembly 30 and the clamping assembly 40 and the wire tube 2 has a sequential order, which can prevent the pressure block assembly 30 and the clamping assembly 40 from moving and interfering during the clamping process.

[0237] The pressure block assembly 30 first abuts against the wire tube 2. That is, the pressure block assembly 30 first abuts the wire tube 2 against the bottom wall of the tube placement groove 11a. The pressure block assembly 30 and the bottom wall of the tube placement groove 11a together restrict the position of the wire tube 2 in the vertical direction, so that the wire tube 2 cannot be displaced in the vertical direction. Then, the clamping assembly 40 clamps the wire tube 2 in the horizontal direction. The first clamping member 41a and the second clamping member 42a together restrict the position of the wire tube 2 in the horizontal direction, so that the wire tube 2 cannot be displaced in the horizontal direction, thereby realizing the complete limiting process of the wire tube 2.

[0238] Please refer to Figure 25. In some embodiments of this application, the pressure block assembly 30 includes a first pressure block 31 and a second rotating shaft 35. The first pressure block 31 is rotatably connected to the pressure cover 20 through the second rotating shaft 35. When the pressure cover 20 is rotated to the closed position, the first pressure block 31 abuts against the wire tube 2. The first pressure block 31 is inclined relative to the pressure cover 20, and there is a first included angle between the first pressure block 31 and the pressure cover 20. When the pressure cover 20 is closed, the pressure cover 20 contacts the surface of the host 10, the wire tube 2 abuts against the first pressure block 31, and pushes the first pressure block 31 to rotate towards the pressure cover 20. At this time, the first included angle between the first pressure block 31 and the pressure cover 20 becomes smaller.

[0239] Further, as shown in Figure 25, the pressure block assembly 30 also includes a first elastic element 32c. The first elastic element 32c is connected to the first pressure block 31 and the pressure cover 20. The first elastic element 32c is sleeved on the second rotating shaft 35. One end of the first elastic element 32c is connected to the first pressure block 31, and the other end is connected to the pressure cover 20. When the pressure cover 20 rotates to the closed position, the first pressure block 31 abuts against the wire tube 2, and the first pressure block 31 squeezes the first elastic element 32c. At this time, the first elastic element 32c undergoes elastic deformation. When the pressure cover 20 rotates away from the main unit 10, the wire tube 2 separates from the first pressure block 31. Under the action of elastic force, the first elastic element 32c can push the first pressure block 31 to rotate to the initial position, that is, reset the first pressure block 31. The first elastic element 32c can be a torsion spring.

[0240] Please continue to refer to Figure 25. In some embodiments of this application, the pressure block assembly 30 includes a second pressure block 33, which is telescopically disposed on the pressure cover 20. When the pressure cover 20 is rotated to the closed position, the second pressure block 33 abuts against the wire tube 2. The second pressure block 33 is disposed perpendicular to the pressure cover 20. When the pressure cover 20 is closed, the pressure cover 20 contacts the surface of the host 10, the wire tube 2 abuts against the second pressure block 33, and pushes the first pressure block 31 to retract toward the pressure cover 20.

[0241] Further, as shown in Figure 25, the pressure block assembly 30 also includes a second elastic element 34c. The second elastic element 34c is connected to the second pressure block 33 and the pressure cover 20. When the pressure cover 20 rotates to the closed position, the second pressure block 33 abuts against the wire tube 2, and the second pressure block 33 presses against the second elastic element 34c. At this time, the second elastic element 34c undergoes elastic deformation. When the pressure cover 20 rotates away from the main unit 10, the second elastic element 34c can push the second pressure block 33 to extend to the initial position under the action of elastic force, that is, reset the second pressure block 33. The second elastic element 34c can be a spring.

[0242] Alternatively, the pressure block assembly 30 may include both the first pressure block 31 and the second pressure block 33 as described in the above embodiments. Please refer to Figures 23 and 25. In some embodiments of this application, the second pressure block 33 is located on the side of the first pressure block 31 near the inlet 12d. When the pressure cover 20 is rotated to the closed position, the second pressure block 33 is located between the first pressure block 31 and the inlet 12d.

[0243] Along the extension direction of the tube-laying groove 11a, the second pressure block 33 is located upstream of the first pressure block 31. The second pressure block 33 can pre-press the wire tube 2, thereby pre-limiting the wire tube 2 in the vertical direction. This ensures that when the wire tube 2 moves to the position of the first pressure block 31, the wire tube 2 is already in contact with the bottom wall of the tube-laying groove 11a. This allows the first pressure block 31 to provide a smaller pressure to limit the wire tube 2. In other words, when the pressure cap 20 rotates to the closed position, the pressure of the second pressure block 33 on the wire tube 2 is greater than the pressure of the first pressure block 31 on the wire tube 2. At this time, the wire tube 2 is not only further limited to the bottom wall of the tube-laying groove 11a by the first pressure block 31, but also the deformation of the wire tube 2 at the first pressure block 31 is reduced. This allows the wire tube 2 to recover its deformation more easily at the clamping assembly 40.

[0244] Furthermore, as shown in Figure 25, the first pressing block 31 has a first free end 311 configured to abut against the wire tube 2, and the second pressing block 33 has a second free end 331 configured to abut against the wire tube 2. The first free end 311 and the second free end 331 are spaced apart along the extension direction of the tube groove 11a, that is, there is a gap between the first free end 311 and the second free end 331. The wire tube 2 is first pressed by the second free end 331, and then the wire tube 2 moves from the second free end 331 to the first free end 311. The gap between the first free end 311 and the second free end 331 can allow the shape of the wire tube 2 to be initially restored.

[0245] The distance between the first free end 311 and the second free end 331 along the extension direction of the tube groove 11a is d2, where d2 satisfies 1cm ≤ d2 ≤ 5cm. If the distance d2 between the first free end 311 and the second free end 331 is too small, the distance between the first pressing block 31 and the second pressing block 33 will be too close, which may cause the wire tube 2 to deform significantly. If the distance d2 between the first free end 311 and the second free end 331 is too large, the wire tube 2 will deform at the second pressing block 33, but because the wire tube 2 is located at... The relatively long distance that the first free end 311 and the second free end 331 move between is a problem. On the one hand, it allows the deformation of the wire tube 2 to be restored. On the other hand, it cannot be guaranteed that the wire tube 2 will always be in contact with the bottom wall of the tube placement groove 11a in the vertical direction. After the wire tube 2 moves between the first free end 311 and the second free end 331, it may tilt upwards. At this time, the first pressure block 31 still needs a large pressure to press the wire tube 2 tightly against the bottom wall of the tube placement groove 11a, which causes the wire tube 2 to undergo a large deformation in the vertical direction.

[0246] It is easy to understand that when the cap 20 is rotated to the closed position, both the first pressure block 31 and the second pressure block 33 abut against the wire tube 2. Therefore, there is an interaction force between the wire tube 2 and the first free end 311 and the second free end 331. At the same time, the wire tube 2 will move in the tube placement groove 11a. In order to reduce the friction between the first free end 311 and the wire tube 2, this embodiment sets the circumference of the first free end 311 to be arc-shaped. The arc-shaped circumference of the first free end 311 contacts the wire tube 2, reducing the damage of the first free end 311 to the wire tube 2. Similarly, in this embodiment, the circumference of the second free end 331 is also set to be arc-shaped, reducing the damage of the second free end 331 to the wire tube 2. The first free end 311 and the second free end 331 can be made of elastic material. When the wire tube 2 comes into contact with the first free end 311 and the second free end 331, the first free end 311 and the second free end 331 can undergo slight deformation, so as to further reduce the damage to the wire tube 2 caused by the first free end 311 and the second free end 331.

[0247] In some other embodiments, as shown in FIG26, a roller groove 312 may be formed on the first free end 311, and a first roller 313 is provided in the roller groove 312. The first roller 313 is rotatably connected to the first free end 311. The roller groove 312 makes the setting and rotation of the first roller 313 more stable. The axle of the first roller 313 is perpendicular to the extension direction of the tube placement groove 11a. When the cover 20 rotates to the closed position, the circumferential side of the first roller 313 abuts against the wire tube 2. When the wire tube 2 moves in the tube placement groove 11a, the friction between the wire tube 2 and the first roller 313 will drive the first roller 313 to rotate, thereby further reducing the friction between the first roller 313 and the wire tube 2, making the movement of the wire tube 2 smoother.

[0248] Similarly, a second roller 332 can be provided on the second free end 331. The second roller 332 is rotatably connected to the second free end 331. The axle of the second roller 332 is perpendicular to the extension direction of the tube placement groove 11a. When the cover 20 rotates to the closed position, the circumferential side of the second roller 332 abuts against the wire tube 2. When the wire tube 2 moves in the tube placement groove 11a, the friction between the wire tube 2 and the second roller 332 will drive the second roller 332 to rotate, thereby further reducing the friction between the second roller 332 and the wire tube 2, making the movement of the wire tube 2 smoother.

[0249] Example 6

[0250] Please refer to Figures 27 to 31. The wire marking machine's crimping module consists of two main parts: the main unit 1 and the cover. The main unit 1 has a wire conduit channel 11b designed as a dedicated channel for accommodating the wire conduit 5. The cover is equipped with a crimping component 2a, which functions to apply pressure to the wire conduit 5. When the cover is closed onto the main unit 1, the crimping component 2a accurately and effectively presses down on the wire conduit 5 already placed in the wire conduit channel 11b, ensuring that the wire conduit 5 maintains a stable and accurate position during use.

[0251] In this device, a pipe-pressing component 2a is provided on the cover. When the cover is closed on the main unit 1, the pipe-pressing component 2a can apply appropriate pressure to the conduit 5 that has been placed in the conduit channel 11b to fix the conduit by pressing. When it is necessary to open the cover to take out the conduit, the pipe-pressing component 2a can open automatically, and when the cover is closed, it will automatically press the conduit 5, making the pipe-taking operation simple and convenient, and effectively solving the problems of difficult pipe insertion and cumbersome manual pipe pressing operation.

[0252] Please refer to Figures 27 to 30. In order to facilitate the installation of the crimping fitting 2a, in this embodiment, the crimping module of the wire marking machine also includes a crimping bracket 3a. The crimping bracket 3a is disposed on the cover of the main unit 1. A rotating shaft is disposed on the crimping bracket 3a. The rotating end of the crimping fitting 2a is rotatably connected to the rotating shaft of the crimping bracket 3a, so that it is connected to the cover through the crimping bracket 3a.

[0253] Since the pressure tube bracket 3a is installed on the cover, as the cover is opened and closed, the pressure tube bracket 3a moves with the cover, forming a closed state and an open state respectively. When the cover is closed, the pressure tube bracket 3a moves accordingly and covers the conduit channel 11b of the main unit 1, forming the closed state. When the pressure tube bracket 3a is in the closed state, the pressure tube component 2a is placed inside the main unit 1 and above the conduit channel 11b, forming the pressure tube state. When the cover is opened, the pressure tube bracket 3a moves accordingly and flips upwards towards the main unit 1, forming the open state. When the pressure tube bracket 3a is in the open state, the pressure tube component 2a detaches from the main unit 1, forming the detached state.

[0254] Please refer to Figures 28 to 30. In some embodiments, the pressing component 2a includes a pressing block 21c, having a rotating end and a pressing end capable of rotating around the rotating end. The rotating end is rotatably connected to the cover. When the cover is closed, the pressing end corresponds to the wire tube channel 11b to press against the wire tube inside the wire tube channel. The wire marking machine pressing module also includes an elastic element 4c, which generates a spring force to drive one end of the pressing component towards the wire tube channel when the cover is closed, so that the pressing component presses the wire tube inside the wire tube channel. For wire tubes 5 of different diameters, the pressing component 2a can adaptively achieve positive pressing through the deformation angle of the elastic element 4c, ensuring that the wire tubes 5 can be printed with the bottom facing down. The rotating end of the pressing block 21c is rotatably connected to the rotating shaft of the pressing bracket 3a. The elastic element 4c includes a torsion spring 41a, which is mounted on the rotating shaft of the pressure tube bracket 3a. One end of the torsion spring 41a is connected to the rotating end of the pressure tube component 2a. The rotating end of the pressure tube component 2a is rotatably connected to the rotating shaft. When the cover is closed, the torsion spring 41a can generate a spring force that drives the pressure tube end of the pressure tube component to rotate around the rotating end toward the conduit channel 11b, so that the pressure tube end presses the conduit inside the conduit channel 11b.

[0255] When the cover is opened, the pressure block 21c is in an open position due to the torque of the torsion spring 41a. When printing with the cover closed, the pressure tube bracket 3a closes, and the pressure block 21c contacts the tube 5 and begins to rotate clockwise. At this time, the torsion spring 41a applies a reverse force, and the pressure block 21c keeps the tube 5 pressed against the printing reference surface of the host 1, preventing the tube 5 from jumping up and down during printing. A brand-new vertical tube placement method is adopted, eliminating the use of the tube adjuster, making the tube placement operation very simple.

[0256] Furthermore, at least two sets of the clamping fittings 2a are provided, with each set corresponding to the inlet and outlet positions of the main body's upper conduit 5, respectively. This allows the clamping block 21c to press against the conduit 5 at the inlet and outlet positions, thereby achieving stable fixation and precise control of the conduit 5.

[0257] Furthermore, in some embodiments, the pressing end of the pressing block 21c is provided with mutually perpendicular curved sections. When the pressing component 2a presses against the conduit, the convex edge of the curved section abuts against the conduit in the conduit channel 11b, thereby realizing the pressing operation.

[0258] It should be noted that in other possible embodiments, the elastic element is not limited to this; the elastic element can also be a spring or a sheet, etc.

[0259] Print maximum (25) 2When the conduit 5 is pressed, the pressure block 21c may jam. Specifically, when the pressure block 21c contacts the conduit 5, it makes perpendicular contact, and due to friction, it cannot rotate clockwise, causing it to jam. To avoid this jamming, please refer to Figures 27 to 31. In this embodiment, a guide post 22c with a cylindrical design is provided on one side of the pressing end of the pressing component 2a for easy sliding. A groove 12c corresponding to the guide post 22c is provided on one side of the conduit channel 11b of the main unit 1. When the pressing component 2a moves from a disengaged state to a pressing state, the guide post 22c can enter the groove 12c and slide along it. Furthermore, before the guide post 22c enters the groove 12c, the pressure block 21c and the conduit remain separated.

[0260] When the pressure tube support 3a is closed, the guide post 22c first contacts the slide groove 12c. The slide groove 12c guides the pressure block 21c to start rotating clockwise. After a certain rotation angle, the pressure block 21c then contacts the conduit 5, preventing jamming. The same applies when opening the cover; the slide groove 12c guides the guide post 22c to flip outward, ensuring that the pressure block 21c can work normally when the cover is opened.

[0261] Furthermore, to ensure the stability of the pressure block 21c during movement, the number of guide posts 22c and slide grooves 12c can be increased. In some other possible embodiments, two guide posts 22c are provided, respectively located on both sides of the pressure tube 2a, and two slide grooves 12c are respectively provided on the main unit 1 at positions corresponding to the two guide posts 22c.

[0262] This application, through the configuration of a host 1, a pressing component 2a, and an elastic component 4c, ensures that the pressing end of the pressing component 2a corresponds to the tubing channel 11b when the cover is closed. Simultaneously, when the cover is closed, the elastic component 4c generates a spring force that drives the pressing end to rotate around the rotating end towards the tubing channel 11b, causing the pressing end to move towards the tubing channel 11b and thus press firmly onto the tubing within the tubing channel 11b. This ensures that the pressing component 2a always presses the tubing 5 against the printing reference surface of the host 1, preventing the tubing 5 from bouncing up and down during printing. For tubing 5 of different diameters, the pressing component 2a can adaptively achieve positive pressing through the deformation angle of the elastic component 4c, ensuring that the tubing 5 is always printed close to the bottom. This device enables normal printing of full-size tubing 5, ensuring normal printer operation and improving product printing stability. The tubing is fixed by pressing, and the tubing clamp 2a can automatically open when the cover is opened and automatically clamp the tubing 5 when the cover is closed. The tubing removal operation is simple and convenient, solving problems such as difficulty in inserting tubing and cumbersome manual tubing pressing operation.

[0263] 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.
