[0050] The embodiment of the present application provides a printer, which can simplify the disassembly steps of the to-be-printed piece, is simple to operate, and improves the use experience of users.

[0051] Specifically, refer to Figure 1 and Figure 2 , Figure 1 a structural schematic view of a printer carrying a to-be-printed piece provided by the embodiment of the present application; Figure 2 a structural schematic view of a printer provided by the embodiment of the present application.

[0052] The printer of the embodiment can be applied to various types, such as a wire number tube printer, a label printer, a barcode printer and the like. Correspondingly, the to-be-printed piece 3 can be a wire number tube, various labels, barcode paper and the like in various forms. Among them, the wire number tube printer is a printer used for printing marks such as numbers, letters, symbols and the like on a wire number tube to mark a cable. In the following, the printer of the embodiment will be described as a wire number tube printer, and the to-be-printed piece 3 will be described as a wire number tube.

[0053] The printer of the embodiment is composed of a host 1 and a cover assembly 2, the host 1 is the core carrying part of the whole printer, which can include a base 11 and a printing assembly and a pipe feeding assembly mounted on the base 11. The print head in the printing assembly is a component for realizing the printing of identification information of the wire number tube, which can accurately print characters, numbers or symbols on the surface of the wire number tube according to the preset instructions. The conveying roller of the pipe feeding assembly is used for conveying the wire number tube, and the base 11 has a carrying part 100 for carrying the to-be-printed piece 3 (wire number tube), for example, the carrying part 100 of the embodiment is a wire running groove formed on the base 11, the wire number tube is arranged in the wire running groove on the base 11 and passes through the conveying roller, the conveying roller gradually conveys the wire number tube to the corresponding position of the print head through the rotating motion, so as to ensure the smooth operation of the printing operation.

[0054] The cover assembly 2 of the embodiment comprises a first movable cover 21 and a second movable cover 22. The first movable cover 21 and the second movable cover 22 are movably connected with the base 11, and the movable connection mode can adopt a hinge, a sliding rail or the like, so as to ensure that the first movable cover 21 and the second movable cover 22 can be flexibly opened and closed, facilitating the installation and dismounting of the cable tube. Exemplarily, the first movable cover 21 and the second movable cover 22 are rotatably connected with the base 11, and the rotatable connection mode can adopt a hinge structure. The first movable cover 21 is used for pressing the cable tube and can press the cable tube in the closed state. Exemplarily, the first movable cover 21 comprises a first cover body 211 and a pressing assembly 215, and the pressing assembly 215 is connected to one side of the first cover body 211 facing the base 11, so as to press the cable tube when the first movable cover 21 is closed on the base 11.

[0055] The first movable cover 21 of the embodiment can be located between the second movable cover 22 and the base 11, and the first movable cover 21 directly contacts and presses the cable tube when the cover assembly 2 is closed, so that the pressing relationship between the first movable cover 21 and the cable tube is more direct, and the cable tube can be more stably fixed. In addition, the first movable cover 21 can also be embedded on the second movable cover 22, for example, the second movable cover 22 has a mounting cavity, and the first movable cover 21 can be mounted in the mounting cavity to realize embedding on the second movable cover 22. When the first movable cover 21 is embedded in the second movable cover 22, the first movable cover 21 is hidden inside the second movable cover 22 in the initial state, and from the appearance, the entire cover assembly 2 presents a relatively simple overall structure.

[0056] In the embodiment, the second movable cover 22 is linked with the first movable cover 21 during the process of rotating from the closed state to the open state, so as to drive the first movable cover 21 to rotate to the open state. Exemplarily, the second movable cover 22 is in transmission connection with the first movable cover 21, so that the second movable cover 22 drives the first movable cover 21 to open when the second movable cover 22 is opened. In one embodiment, the second movable cover 22 and the first movable cover 21 are in transmission through a gear set, and the second movable cover 22 and the first movable cover 21 are respectively provided with gears that mesh with each other at specific positions. When the second movable cover 22 rotates to open, the first movable cover 21 is driven to open through the gear set. This transmission mode utilizes the mechanical characteristics of gear transmission, and can stably realize the linkage between the second movable cover 22 and the first movable cover 21. In another embodiment, the second movable cover 22 and the first movable cover 21 are in transmission through a chain, and the second movable cover 22 and the first movable cover 21 are respectively provided with a chain and a sprocket that cooperate at specific positions. The chain is wound around the two sprockets to form a closed transmission chain. When the second movable cover 22 rotates to open, the sprocket at the second movable cover 22 drives the chain to move, and the chain in turn drives the sprocket at the first movable cover 21 to rotate, so that the first movable cover 21 realizes the opening action.

[0057] In use of the printer of the present embodiment, the operator firstly inserts the cable tube into the cable groove of the base 11 of the host 1, and passes it through the conveying roller of the cable feeding assembly, and then closes the first movable cover 21 and the second movable cover 22 on the base 11. At this time, under the cooperation of the second movable cover 22 and the first movable cover 21, the cable tube is stably pressed at the printing position. When it is necessary to disassemble the cable tube, only the second movable cover 22 needs to be opened. Since the second movable cover 22 is linked with the first movable cover 21, the opening of the second movable cover 22 will drive the opening of the first movable cover 21, thereby automatically releasing the pressing of the cable tube. The operator can easily take out the cable tube from the cable groove without additional complex operation to release the pressing of the cable tube by the first movable cover 21 alone. In this way, the disassembly step of the cable tube is simplified, the operation time and labor intensity of the operator are reduced, and the work efficiency and use experience are greatly improved.

[0058] Please refer to Figures 3 to 5 , Figure 3 the structural schematic diagram of the printer provided by the present embodiment after hiding part of the structure of the host 1; Figure 4 the structural schematic diagram of the driving arm 222, the transmission member 23, the first elastic member 24 and the linkage arm 212 provided by the present embodiment; Figure 5 another structural schematic diagram of the driving arm 222, the transmission member 23, the first elastic member 24 and the linkage arm 212 provided by the present embodiment;

[0059] The cover assembly 2 of the present embodiment further comprises a transmission member 23, which is a key component for linkage between the second movable cover 22 and the first movable cover 21.

[0060] Specifically, the first movable cover 21 further comprises a linkage arm 212, which is connected with the first cover body 211, and specifically can be integrally formed with the first cover body 211. The linkage arm 212 is rotationally connected with the base 11, and the rotational connection mode can be that a rotating shaft is simultaneously provided in the linkage arm 212 and the base 11, or the linkage arm 212 is connected with the base 11 through a hinge structure.

[0061] The second movable cover 22 comprises a second cover body 221 and a driving arm 222 connected with each other. The second cover body 221 covers the bearing part 100 of the host 1 in the closed state, thereby providing a relatively closed and stable environment for the printing operation, and reducing the interference of external factors such as dust and air flow on the printing process. The driving arm 222 is rotationally connected with the base 11, and the rotational connection mode can be that a rotating shaft is simultaneously provided in the linkage arm 212 and the base 11, or the linkage arm 212 is connected with the base 11 through a hinge structure.

[0062] The transmission member 23 is rotationally connected to the base 11, one end of the transmission member 23 is used to abut against the driving arm 222, and the other end is connected to the linkage arm 212 through the first elastic member 24, so as to link the second movable cover 22 with the first movable cover 21. Specifically, as shown in Figure 4 The transmission member 23 includes a connecting portion 231 and an abutting portion 232. The connecting portion 231 is connected to the linkage arm 212 through the first elastic member 24, and the abutting portion 232 is connected to the connecting portion 231 at an angle and is used to abut against the driving arm 222, and the connecting position of the abutting portion 232 and the connecting portion 231 is rotationally connected to the base 11. In this way, the transmission member 23 can transmit power during the linkage of the first movable cover 21 and the second movable cover 22.

[0063] When the second movable cover 22 rotates in the closing direction (counterclockwise direction in the figure), the driving arm 222 abuts against the abutting portion 232 of the transmission member 23, driving the transmission member 23 to rotate in the opening direction (clockwise direction in the figure), and the connecting portion 231 of the transmission member 23 is connected to the linkage arm 212 of the first movable cover 21 through the first elastic member 23, so that when the transmission member 23 rotates in the opening direction, the linkage arm 212 will be driven to rotate in the closing direction, so that the first movable cover 21 is closed on the base 11, and at this time, the first elastic member 24 stores elastic potential energy. The first elastic member 24 includes one of a tension spring and an elastic rubber piece, and the first elastic member 24 of the embodiment is a tension spring, which is in a stretched state when the first movable cover 21 is in a closed state.

[0064] As shown in Figure 5 When the second movable cover 22 is opened, the driving arm 222 rotates in the opening direction (clockwise direction in the figure), and at this time, the driving arm 222 is out of contact with the abutting portion 232 of the transmission member 23. Since the driving arm 222 no longer applies driving force to the transmission member 23, the elastic potential energy stored in the first elastic member 24 is released, and the released elastic potential energy drives the linkage arm 212 to rotate in the opening direction (clockwise direction in the figure), thereby realizing the opening action of the first movable cover 21.

[0065] The linkage structure of the second movable cover 22 and the first movable cover 21 of the embodiment greatly simplifies the disassembly steps of the wire number tube. Only the second movable cover 22 needs to be opened, and the first movable cover 21 will automatically follow to be opened. The operator can directly take out or replace the wire number tube, reducing the operation steps and improving the work efficiency.

[0066] Further, the driving arm 222 of the embodiment has a first contact surface 2221 which is an arc surface, and the abutting part 232 has a second contact surface 2321 for abutting with the first contact surface 2221, the second contact surface 2321 being a plane. When the driving arm 222 rotates along the cover closing direction (counterclockwise direction), the arc-shaped first contact surface 2221 gradually approaches and contacts the second contact surface 2321 of the transmission member 23 and presses the transmission member 23, thereby driving the transmission member 23 to rotate along the cover opening direction (clockwise direction) and realizing the cover closing of the first movable cover 21 by the second movable cover 22.

[0067] When the first movable cover 21 needs to be opened, the driving arm 222 rotates along the cover opening direction (clockwise direction). Due to the special geometric relationship between the first contact surface 2221 (arc surface) and the second contact surface 2321 (plane), the arc surface gradually separates from the plane during the rotation of the driving arm 222, and at this time the transmission member 23 is no longer pressed by the driving arm 222. With the continuous rotation of the driving arm 222, the elastic potential energy stored by the tension spring is released, and the released elastic potential energy is converted into kinetic energy, driving the linkage arm 212 to rotate along the cover opening direction (clockwise direction) and realizing the automatic opening action of the first movable cover 21.

[0068] Please refer to Figure 6 and Figure 7 , Figure 6 Another structural schematic view of the printer provided by the embodiment of the present application and provided with a wire number tube is shown in FIG. 6. Figure 7 is Figure 6 an enlarged view of A in FIG. 6.

[0069] The cover assembly 2 of the embodiment further includes a second elastic member 25 which plays a key auxiliary role in the automatic opening process of the first movable cover 21, and the second elastic member 25 includes one of a torsion spring and an elastic rubber member.

[0070] Specifically, the second elastic member 25 is a torsion spring which can store and release elastic potential energy in the process of torsion deformation. One end of the second elastic member 25 is connected with the first movable cover 21, specifically with the linkage arm 212 of the first movable cover 21. The other end of the second elastic member 25 is connected with the base 11, and the base 11 is provided with a recess or a protruding structure at a corresponding position, and the end of the second elastic member 25 can stably abut on the recess or the protruding structure. When the first movable cover 21 is in the cover closing state, due to the cover closing action of the second movable cover 22 and the action of the transmission member 23 on the linkage arm 212, the second elastic member 25 is twisted by a certain angle and stores elastic potential energy.

[0071] The first movable cover 21 of the embodiment further comprises a limiting part 213 located at one side of the linkage arm 212. The limiting part 213 plays a multi- role in the structure of the first movable cover 21. On the one hand, the limiting part 213 limits the second elastic member 25 (torsion spring) by virtue of its positional relationship with the linkage arm 212. A specific space is formed between the limiting part 213 and the linkage arm 212, and the second elastic member 25 is placed in the space. The limiting part 213 can prevent the second elastic member 25 from being displaced laterally or deviating from its normal working position during operation. For example, the linkage arm 212 is connected to the base 11 through a rotating shaft. In the axial direction of the rotating shaft, the limiting part 213 is arranged at a distance from the linkage arm 212. The second elastic member 25 is arranged on the rotating shaft between the limiting part 213 and the linkage arm 212. The rotating shaft limits the radial movement of the second elastic member 25, and the distance between the limiting part 213 and the linkage arm 212 controls the axial position of the second elastic member 25, thereby ensuring that the second elastic member 25 always maintains a normal working position during torsion. On the other hand, the above-mentioned limiting structure simplifies the overall structural design of the first movable cover 21. The embodiment does not require additional complex elastic member fixing devices, thereby reducing the number of parts and assembly difficulty of the first movable cover 21.

[0072] When it is necessary to open the first movable cover 21, the driving arm 222 rotates in the opening direction (clockwise direction). The driving arm 222 is disengaged from the transmission member 23, and the first elastic member 24 (e.g., a tension spring) releases the elastic potential energy to drive the linkage arm 212 to rotate in the opening direction (clockwise direction). Meanwhile, the second elastic member 25 (torsion spring) assists the opening action of the first movable cover 21 to be smoother. The second elastic member 25 releases the elastic potential energy stored during the closing of the first movable cover 21, thereby generating an auxiliary torque that cooperates with the tension of the first elastic member 24 to accelerate the rotation of the linkage arm 212, so that the first movable cover 21 can be quickly and smoothly opened.

[0073] Please refer to Figure 8 , Figure 8 The rotating arm 214 provided in the embodiment and part of the structure of the host 1 are shown in the schematic diagram.

[0074] The first movable cover 21 of the embodiment further comprises a rotating arm 214 that serves as a rotating connecting component between the first movable cover 21 and the host 1. The structure of the rotating arm 214 takes into account both strength and flexibility. For example, the rotating arm 214 can be made of high-strength engineering plastic or lightweight alloy material, and has a certain rigidity to ensure that it will not be excessively deformed when bearing various forces during the rotation of the first movable cover 21. The length of the rotating arm 214 can be determined according to the size and rotation radius requirements of the first movable cover 21, and the cross-sectional shape of the rotating arm 214 can be circular, rectangular, or irregular.

[0075] The base 11 of the host 1 is formed with a mounting groove 200, which has multiple functions. On the one hand, the mounting groove 200 is used for mounting the rotating arm 214 and plays a role of avoiding interference and collision between the rotating arm 214 and other parts of the base 11. For example, the shape and size of the mounting groove 200 are designed according to the contour and rotating track of the rotating arm 214, so as to ensure that the rotating arm 214 can rotate freely in the mounting groove 200 without being collided or hindered due to insufficient space, thereby facilitating the opening of the first movable cover 21. On the other hand, the inner side wall of the mounting groove 200 abuts against the side wall of the rotating arm 214, so as to limit the position of the rotating arm 214 and ensure the stability of the rotation of the first movable cover 21. One of the inner side wall of the mounting groove 200 and the side wall of the rotating arm 214 is provided with a third contact surface 2141, which is an arc surface. The arc-shaped third contact surface 2141 can effectively reduce the contact area between the rotating arm 214 and the inner side wall of the mounting groove 200, thereby reducing the friction force received by the first movable cover 21 during rotation, thereby facilitating the opening of the first movable cover 21. At the same time, the inner walls on both sides of the mounting groove 200 can also limit the rotating arm 214 in the mounting groove 200, thereby ensuring sufficient contact stability and preventing the rotating arm 214 from shaking or deviating.

[0076] Further, the contact area between the side wall of the rotating arm 214 and the inner side wall of the mounting groove 200 is controlled to be not less than 1mm 2 and not more than 4mm 2 . When the contact area is less than 1mm 2 , the abutting relationship between the rotating arm 214 and the mounting groove 200 can be unstable and gaps can be easily generated, thereby being unable to effectively limit the position of the rotating arm 214 and causing excessive deviation of the rotating arm 214 during rotation. When the contact area is greater than 4mm 2 , the friction force between the rotating arm 214 and the inner side wall of the mounting groove 200 is increased, which is not conducive to the smooth opening of the first movable cover 21.

[0077] Please refer to Figure 9 , Figure 9 the structural schematic diagram of the first movable cover 21 and the third elastic member 26 provided in the embodiment of the present application.

[0078] The pressing assembly 215 of the embodiment is elastically connected to the first cover body 211, which is not only used for pressing the cable number tube, but also plays an auxiliary role in the automatic opening process of the first movable cover 21.

[0079] Specifically, the pressing assembly 215 includes at least one pressing block 2151, which is a component directly contacting and fixing the cable number tube and has certain hardness and wear resistance, for example, is made of hard rubber or engineering plastic. The shape of the pressing block 2151 is cylindrical, for example, a pressing roller.

[0080] The third elastic member 26 is arranged between the pressing block 2151 and the first cover body 211, and can be a compression spring or a torsion spring. Taking the compression spring as an example, one end of the compression spring is connected to the pressing block 2151, and a connecting column or a groove is arranged on the pressing block 2151, and the end of the compression spring can be sleeved or clamped in the connecting column or the groove. The other end of the compression spring is connected to the first cover body 211, and a mounting seat is arranged at a corresponding position of the first cover body 211, and the compression spring can be mounted on the mounting seat. When the pressing block 2151 presses the cable marker, the compression spring will be compressed and store elastic potential energy due to the closing action of the first movable cover 21 and the reaction force of the cable marker. For example, in the normal working state of the printer, the first movable cover 21 is closed, the pressing block 2151 is driven downward by the first cover body 211, the compression spring is gradually compressed, and the stored elastic potential energy increases with the increase of the compression amount, and at this time the cable marker is stably fixed between the base 11 and the pressing block 2151, which ensures the accuracy and stability of the printing process.

[0081] When the first movable cover 21 needs to be opened, the third elastic member 26 (such as the compression spring) originally in the compressed state and storing elastic potential energy begins to release the elastic potential energy. The elastic force of the compression spring pushes the first movable cover 21 upward, thereby improving the smoothness of the opening of the first movable cover 21. When two or more pressing blocks 2151 are arranged, for example, two pressing blocks 2151 are arranged at intervals, and each pressing block 2151 is connected to an independent third elastic member 26, the two third elastic members 26 release the elastic force at the same time. The resultant force of the two elastic forces acts more uniformly on the first movable cover 21, so that the first movable cover 21 can be opened more smoothly, thereby improving the opening speed and smoothness of the first movable cover 21.

[0082] The above are only preferred embodiments of the present application, and are not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
