[0003] In order to achieve the functions of conveying and printing wire marking tubes, related technologies usually use complex drive and transmission mechanisms to drive components such as the conveyor roller and printing roller in the wire marking printer, resulting in a complex structure for the wire marking printer.

[0091] A wire marking printer, also known as a wire marking machine, can print characters on wire tubes such as sleeves and heat shrink tubing for marking wiring in electrical control and power distribution equipment.

[0092] In order to achieve the functions of conveying and printing wire marking tubes, related technologies usually use complex drive and transmission mechanisms to drive components such as the conveyor roller and printing roller in the wire marking printer, resulting in a complex structure for the wire marking printer.

[0093] To address the aforementioned technical problems, this application provides a line marking printer. The following is a detailed description of the line marking printer provided in this application, with reference to the accompanying drawings.

[0094] Please refer to Figures 1 to 3 This application discloses a line marking printer 1, which includes a conveyor roller group 100, a printing roller group 200, a transmission mechanism 300, and a motor 400. The transmission mechanism 300 is connected to the conveyor roller group 100 and the printing roller group 200 for transmission; the motor 400 is connected to the transmission mechanism 300 and can drive the conveyor roller group 100 and the printing roller group 200.

[0095] The wire marking printer 1 is used to print characters on the surface of the wire marking tube 2, and can cut the wire marking tube 2 after printing. The conveyor roller group 100, as a core component of the wire marking printer 1, is used to drive the wire marking tube 2 to move continuously through its own rotation during the character printing process.

[0096] The printing roller assembly 200 is used to transfer ink. During rotation, the printing roller assembly 200 can transfer ink evenly and clearly to the surface of the wire marking tube 2. Therefore, when the wire marking printer 1 is working normally, both the conveyor roller assembly 100 and the printing roller assembly 200 require external force to drive them.

[0097] The transmission mechanism 300 is used to transmit and convert motion and power. For example... Figure 2 and Figure 3 As shown, the transmission mechanism 300 can employ various mechanical transmission mechanisms, such as gear transmission mechanisms. Gear transmission mechanisms transmit motion and power through the meshing of one or more gears, thereby achieving the transmission, conversion, and distribution of motion.

[0098] In the solution provided in this application, the motor 400 is connected to the conveyor roller group 100 and the printing roller group 200 via the transmission mechanism 300. When the motor 400 is turned on, it can simultaneously drive the conveyor roller group 100 and the printing roller group 200 through the transmission mechanism 300, realizing the conveying and printing functions of the wire marking tube 2. Compared with the related technologies that use multiple motors to drive the conveyor roller group and the printing roller group separately, the solution in this application reduces the number of motors and effectively reduces the structural complexity of the wire marking printer.

[0099] It should be noted that when a single motor 400 drives both the conveyor roller group 100 and the printing roller group 200, the transmission mechanism 300 can adopt different structural forms.

[0100] See Figure 4 In some embodiments, the transmission mechanism 300 may include a first transmission group 310 and a second transmission group 320. The motor 400 is connected to the conveyor roller group 100 via the first transmission group 310; the conveyor roller group 100 is connected to the printing roller group 200 via the second transmission group 320.

[0101] In other words, the motor 400 can be connected in series with the conveyor roller group 100 and the printing roller group 200 via the first transmission group 310 and the second transmission group 320. Specifically, the motor 400 can first be connected to the conveyor roller group 100 via the first transmission group 310, and then connected to the printing roller group 200 via the conveyor roller group 100, thereby sequentially driving the conveyor roller group 100 and the printing roller group 200. This series connection method has a relatively simple structure, weak correlation between the motor 400 and the conveyor roller group 100 and the printing roller group 200, and flexible placement, making it highly adaptable.

[0102] In some embodiments, the transmission mechanism 300 may also include a first transmission group and a second transmission group; the motor 400 is connected to the conveyor roller group 100 via the first transmission group and to the printing roller group 200 via the second transmission group. That is, the motor 400 can be connected to both the conveyor roller group 100 and the printing roller group 200 in parallel via the first and second transmission groups. Specifically, the motor 400 is connected to the conveyor roller group 100 via the first transmission group and to the printing roller group 200 via the conveyor roller group, thus simultaneously driving both the conveyor roller group 100 and the printing roller group 200. This parallel connection method, with the motor 400 positioned between the first and second transmission groups, requires more space for arrangement, but with proper placement, it offers excellent operational reliability. A failure in one of the first or second transmission groups will not affect the normal operation of the other.

[0103] When the motor 400 is connected in series with the conveyor roller group 100 and the printing roller group 200 through the first transmission group 310 and the second transmission group 320, it can drive the conveyor roller group 100 and the printing roller group 200 to rotate in sequence.

[0104] See Figure 3 In some embodiments, the line marking printer 1 may further include a mounting frame 500, with the conveyor roller assembly 100, the printing roller assembly 200, the transmission mechanism 300, and the motor 400 all mounted on the mounting frame 500. The conveyor roller assembly 100 includes a first gear assembly 110 and a conveyor roller 120. The first gear assembly 110 includes a first gear 111, which meshes with the output end of the first transmission assembly 310, and the input end of the first transmission assembly 310 meshes with the output end of the motor 400; the conveyor roller 120 is fixedly connected to the first gear 111.

[0105] Mounting bracket 500 serves as the mounting base for conveyor roller assembly 100, printing roller assembly 200, transmission mechanism 300, and motor 400, providing reliable support and fixation. Mounting bracket 500 can adopt various support structures, or it can adopt a specially designed main board or core board. This application does not specifically limit the structure of mounting bracket 500, and designers can design it flexibly.

[0106] like Figure 3 As shown, the motor 400 is connected to the input end of the first transmission group 310 and can drive the first transmission group 310 to move. The output end of the first transmission group 310 is connected to the first gear 111 of the conveyor roller group 100 and can drive the first gear 111 of the conveyor roller group 100 to rotate, thereby driving the conveyor roller 120 fixedly connected to the first gear 111 to rotate.

[0107] Please continue reading Figure 3 In some embodiments, the printing roller assembly 200 may include a second gear assembly 210 and a printing roller 220. The second gear assembly 210 includes a second gear that meshes with the output end of a second transmission assembly 320, and the input end of the second transmission assembly 320 meshes with a first gear 111; the printing roller 220 is fixedly connected to the second gear. Figure 3 As shown, the first gear 111 of the conveyor roller assembly 100 meshes with the input end of the second transmission assembly 320, and the output end of the second transmission assembly 320 meshes with the second gear of the printing roller assembly 200. When the motor 400 drives the first gear 111 of the conveyor roller assembly 100 to rotate through the first transmission assembly 310, the first gear 111 of the conveyor roller assembly 100 can drive the second transmission assembly 320 to move. Then, the second transmission assembly 320 can drive the second gear of the printing roller assembly 200, thereby driving the printing roller 220, which is fixedly connected to the second gear, to rotate.

[0108] To prevent the wire marking tube 2 from buckling and deforming during printing, which could lead to printing problems, in some embodiments, the linear speed of the conveyor roller 120 is equal to the linear speed of the printing roller 220. This ensures that the moving speed of the wire marking tube 2 matches the printing speed, allowing it to move simultaneously with printing and preventing bending and deformation caused by excessively fast movement, which would affect the printing quality of the wire marking tube 2.

[0109] It is understandable that there are multiple ways to achieve the same rotational linear velocity between the conveyor roller 120 and the printing roller 220. For example, the outer diameter of the conveyor roller 120 can be set to be the same as that of the printing roller 220, and a suitable second transmission group 320 can be selected to mesh with the first gear 111 of the conveyor roller group 100 and the second gear of the printing roller group 200, so that the conveyor roller 120 and the printing roller 220 have equal rotational angular velocities. Alternatively, the outer diameter of the conveyor roller 120 can be set to be different from that of the printing roller 220, and by adjusting the transmission ratio between the second transmission group 320 and the first gear 111 of the conveyor roller group 100, and the transmission ratio between the second transmission group 320 and the second gear of the printing roller group 200, the conveyor roller 120 and the printing roller 220 can have equal rotational linear velocities.

[0110] Based on their working principles, label printers can be divided into thermal transfer printers and thermal printers. Thermal transfer printers not only achieve high-speed printing but also print high-resolution, clear barcodes or serial numbers. The printed labels have better resistance to high and low temperatures, sunlight, scratches, corrosion, solvents, and water and oil, allowing for long-term preservation. Thermal transfer printing requires the use of a ribbon. Under the influence of heat and pressure, the ink on the ribbon is transferred to the label material, forming the desired text, patterns, or barcodes.

[0111] See Figure 3 In some embodiments, when the line number printer 1 is a thermal transfer printer, it may further include a mounting base 510, which is spaced apart on one side of the mounting frame 500 for mounting the ribbon; the first transmission group 310 may include at least one intermediate gear assembly 311, which includes a rotating shaft 3111 and an intermediate gear. One end of the rotating shaft 3111 is rotatably connected to the mounting frame 500, and the other end of the rotating shaft 3111 abuts against the bottom of the mounting base 510; the intermediate gear is fixedly connected to the rotating shaft 3111.

[0112] There can be one intermediate gear assembly 311, but as many intermediate gear assemblies 311 as possible can be set, provided space allows. For example... Figure 3 As shown, the end of the intermediate gear assembly 311 near the mounting base 510 can abut against the bottom of the mounting base 510. In this way, additional parts can be omitted to fix the intermediate gear assembly 311, and the positioning of the intermediate gear assembly 311 can be directly realized. Therefore, the structure of the line number printer 1 can be further simplified and the cost can be reduced.

[0113] Gear transmission mechanisms typically transmit motion and power through the meshing of multiple gears, thereby achieving the transmission, conversion, and distribution of motion. To further reduce the structural complexity of the line number printer 1, see [link to relevant documentation]. Figure 3 In some embodiments, the second transmission group 320 may include only one external gear, which meshes with the first gear 111 of the conveyor roller group 100 and the second gear of the printing roller group 200.

[0114] One external gear of the second transmission group 320 meshes simultaneously with the first gear 111 of the conveyor roller group 100 and the second gear of the printing roller group 200, driving the conveyor roller group 100 and the printing roller group 200 to rotate, which can effectively reduce the structural complexity of the line number printer 1. Designers can select an external gear of appropriate specifications and dimensions for the second transmission group 320 according to actual needs to meet requirements such as strength, service life, and the consistency of the rotational linear speed of the conveyor roller 120 with the rotational linear speed of the printing roller 220. The specific structure of the external gear of the second transmission group 320 is not specifically limited in this embodiment.

[0115] See Figure 3 and Figure 4In some embodiments, the conveyor roller assembly 100 may further include a fourth gear 112, which is fixedly connected to the first gear 111; the wire marking printer 1 may further include a floating roller assembly 600, which is movable relative to the conveyor roller assembly 100 and has an engaged position and a disengaged position; the floating roller assembly 600 includes a third gear assembly 610 and a floating roller 620. The third gear assembly 610 includes a third gear, which engages with the fourth gear 112 when the floating roller assembly 600 is in the engaged position; the floating roller 620 is fixedly connected to the third gear, and when the floating roller assembly 600 is in the engaged position, the floating roller 620 rotates in cooperation with the conveyor roller 120 to clamp and convey the wire marking tube 2.

[0116] It should be noted that in order to realize the movement of the wire tube 2, a floating roller group 600 is also required on the basis of the conveying roller group 100. The floating roller group 600 cooperates with the conveying roller group 100 to generate a force to drive the wire tube 2 to move through friction between the floating roller group 600 and the wire tube 2 after clamping the wire tube 2.

[0117] Considering the need for convenient handling of the wire marking tube 2 when using the wire marking printer 1, in this embodiment, the floating roller group 600 is movable relative to the conveyor roller group 100, and has an engaging position and a disengaged position; when the floating roller group 600 is in the engaging position, it cooperates with the conveyor roller group 100 to clamp and drive the wire marking tube 2 to move; when the floating roller group 600 is in the disengaged position, the floating roller group 600 and the conveyor roller group 100 are no longer in contact with the wire marking tube 2, and a large distance is maintained between them, thereby facilitating the handling of the wire marking tube 2.

[0118] When the floating roller assembly 600 is in the disengaged position, the third gear of the floating roller assembly 600 is disengaged from the fourth gear 112 of the conveyor roller assembly 100; the conveyor roller assembly 100 cannot drive the floating roller assembly 600 to rotate. When the floating roller assembly 600 is in the engaged position, the third gear of the floating roller assembly 600 is engaged with the fourth gear 112 of the conveyor roller assembly 100; the conveyor roller assembly 100 can drive the floating roller assembly 600 to rotate, thereby causing the floating roller 620 to rotate in coordination with the conveyor roller 120, clamping and conveying the wire gauge tube 2.

[0119] To achieve the movement of the floating roller group 600 relative to the conveyor roller group 100, it is usually necessary to add an additional motor and transmission mechanism, which would increase the structural complexity of the wire marking printer 1. To avoid increasing the structural complexity of the wire marking printer 1, this application achieves the movement of the floating roller group 600 relative to the conveyor roller group 100 by means of linkage.

[0120] See Figure 4In some embodiments, the line number printer 1 may further include a cover 700, a support assembly 800, and an adapter 900. The cover 700 is rotatable about a first axis and has an open position and a closed position; the support assembly 800 is rotatably connected to the mounting frame 500 about a second axis; the floating roller group 600 is fixedly disposed on the support assembly 800; wherein the second axis intersects the first axis; the adapter 900 is movably connected to the mounting frame 500 and is connected to the cover 700 and the support assembly 800 respectively, for converting the rotational motion of the cover 700 about the first axis into the rotational motion of the support assembly 800 about the second axis, so that when the cover 700 is in the closed position, the floating roller group 600 moves to the engagement position.

[0121] It should be noted that, see Figure 4 and Figure 7 The adapter body 910 can be movably connected to the mounting bracket 500 by a rotatable connection, or it can be movably connected to the mounting bracket 500 by a sliding or other means.

[0122] This embodiment utilizes the torque generated when the cover 700 is closed to move the floating roller group 600 relative to the conveyor roller group 100. The support assembly 800 provides support for the floating roller group 600. Since the second axis of rotation of the support assembly 800 intersects the first axis of rotation of the cover 700, the rotational motion of the cover 700 around the first axis is converted into rotational motion of the support assembly 800 around the second axis via the adapter 900 between the support assembly 800 and the cover 700. This allows the floating roller group 600 to move to the open position when the cover 700 is in the open position, and to the engaged position when the cover 700 is in the closed position.

[0123] See Figures 4 to 7 In some embodiments, the adapter 900 may include an adapter body 910, a first protrusion 911, and a second protrusion 912. The adapter body 910 is rotatably connected to the mounting bracket 500 about a third axis, wherein the third axis intersects the second axis; the first protrusion 911 and the second protrusion 912 are disposed on the adapter body 910, and the first protrusion 911 is connected to the support assembly 800; the cover 700 is provided with a driving part 710, which abuts against the second protrusion 912 when the cover 700 is rotated about the first axis to the closed position, thereby driving the adapter body 910 to rotate about the third axis, so that the first protrusion 911 drives the support assembly 800 to rotate about the second axis to the engagement position.

[0124] The first protrusion 911 and the second protrusion 912 are protruding structures on the surface of the adapter body 910. The first protrusion 911 can be connected to the support assembly 800 by direct or indirect connection. For example, for direct connection, the first protrusion 911 and the support assembly 800 can be injection molded into a single structural component, or an adhesive can be used to connect the first protrusion 911 and the support assembly 800 into a single unit. Alternatively, for direct connection, in some embodiments, the adapter 900 may also include a connector 913, one end of which is connected to the first protrusion 911, and the other end of which is connected to the support assembly 800. The connector 913 can be a rigid component, such as a connecting rod. Furthermore, in some embodiments, the connector 913 can also be an elastic or flexible component. For example, the connector 913 can be a tension spring, a rope, or a rubber band. Using an elastic or flexible component to connect the first protrusion 911 and the support assembly 800 allows for smoother movement of the support assembly 800.

[0125] The drive unit 710 is a protruding structure provided on the cover 700. When the cover 700 is opened or closed, i.e. in the open or closed position, the drive unit 710 of the cover 700 can act on the second protrusion 912 of the adapter 900, drive the adapter body 910 and the first protrusion 911, and then drive the support assembly 800 and the floating roller group 600 on it to move through the first protrusion 911. Finally, the floating roller group 600 moves relative to the conveyor roller group 100.

[0126] See Figure 6 In some embodiments, the support assembly 800 may include a column 810, a support plate 820, and an elastic reset member 830. The column 810 is fixedly connected to the mounting bracket 500; the support plate 820 is rotatably connected to the column 810, and the floating roller assembly 600 is fixedly disposed on the support plate 820; the elastic reset member 830 is used to provide an elastic force to the support plate 820 so that when the cover 700 is in the open position, the floating roller assembly 600 moves to the separated position.

[0127] The column 810 is fixedly connected to the mounting bracket 500, providing support for the support plate 820. The floating roller assembly 600 is fixedly mounted on the support plate 820. The support plate 820 is rotatably connected to the column 810, enabling the floating roller assembly 600 on it to rotate relative to the column 810.

[0128] Considering that when the cover 700 is opened, and the cover 700 is in the open position, the floating roller group 600 needs to move relative to the conveyor roller group 100 to the separated position, and at this time the driving part 710 of the cover 700 no longer presses against the second protrusion 912 of the adapter 900, this embodiment of the application also provides an elastic reset member 830. When the cover 700 is in the open position, the elastic reset member 830 can provide elastic force to move the floating roller group 600 to the separated position. Figure 4 and Figure 6 As shown, the elastic reset element 830 can be a tension spring, with one end connected to the mounting bracket 500 and the other end connected to the support plate 820. Alternatively, the elastic reset element 830 can also be a torsion spring, which can be fitted onto the column 810, with one end connected to the column 810 and the other end connected to the support plate 820.

[0129] To make the movement of the floating roller group 600 relative to the conveyor roller group 100 more smooth, see [reference needed]. Figure 6 In some embodiments, the support plate 820 is further provided with an arc-shaped guide hole 821; the support assembly 800 may also include a guide post 840, one end of which is fixedly connected to the mounting bracket 500, and the other end of which extends into the arc-shaped guide hole 821.

[0130] Understandably, the cooperation between the guide post 840 and the arc-shaped guide hole 821 allows the support assembly 800 and the floating roller group 600 on it to move along a predetermined path. Furthermore, when the support assembly 800 moves relative to the conveyor roller group 100, the arc-shaped guide hole 821 can contact its wall to block the support assembly 800, thereby effectively restricting the degree of freedom of movement of the support assembly 800.
