[0002] In modern office and industrial environments, label printer modules are widely used in various fields such as item identification, asset management, and packaging marking due to their high efficiency and convenience. Among them, the print head component TPH, as the core component of the label printer, is responsible for converting electronic signals into actual print outputs, and its performance directly affects print quality and speed. However, during the production or maintenance stage, the disassembly and replacement of the print head component often pose a challenge.

[0003] Most existing label printer module designs are relatively complex, including multiple components such as a main body bracket, a print head, a rubber roller, a fixing plate, an opto-coupler, and a paper reel. These components need to be precisely matched during the assembly process, and the size constraints in the original design make it inconvenient to disassemble each component during production or maintenance.

[0004] In addition, due to the relatively large volume of the overall print module, this not only increases transportation costs but also causes waste of resources.

[0005] In view of this, the inventor has specifically designed a modular movement structure, and this case is thus generated. Summary of the Utility Model

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0043] Please refer to Figures 1 to 8 , which is a modular movement structure as the best embodiment of the present utility model, including:

[0044] The main body bracket 10 is in a plate shape, and its two side wall surfaces 11 serve as the installation bases;

[0045] In this embodiment, the main body bracket 10 is an installation panel 52, and the front and rear side wall surfaces 11 of the installation panel 52 serve as the installation bases for each module. Each module is detachably fixed on the installation panel 52 by means of screwing.

[0046] The paper roll fixing group 20 has a paper outlet roller 23 for placing the printing paper roll;

[0047] In this embodiment, the paper roll fixing group 20 further includes a fixing seat 21 in a flat cylindrical shape. The fixing seat 21 is detachably fixed to the main body bracket 10 by a first screw 22, and the first screw 22 penetrates into the fixing seat 21 from the other side of the main body bracket 10. Among them, the paper outlet roller 23 is rotatably connected to the fixing seat 21. In this embodiment, the paper outlet roller 23 includes a rotating cylinder 231 at the center and three side cylinders 232 evenly distributed around the rotating cylinder 231. The outer peripheral sides of the three side cylinders 232 are all arc-shaped and coincide with the edge of the same cylindrical peripheral surface. The fixing seat 21 extends a paper outlet shaft (not shown in the figure). The rotating cylinder 231 is rotatably sleeved on the outer peripheral side of the paper outlet shaft and is limited and fixed by a first limit screw 24. Thus, the paper outlet roller 23 can rotate around the paper outlet shaft. When the printing paper roll is sleeved on the paper outlet roller 23, under the action of an external power source, the printing paper is drawn out, and the paper outlet roller 23 rotates in cooperation with the drawing out of the printing paper, so as to realize the smooth paper outlet of the printing paper.

[0048] The rubber roller group 30 has a rubber roller 31 for guiding the paper and providing pressure to the printing paper;

[0049] In this embodiment, the rubber roller group 30 includes an inner plate 32, an outer plate 33, a plurality of guide shafts 34 parallel and hinged between the inner plate 32 and the outer plate 33, and a rubber roller 31 hinged between the inner plate 32 and the outer plate 33. The rotating shaft of the rubber roller 31 passes through the inner plate 32 and the main bracket 10 in sequence and is connected to the output shaft of the driving motor. Three extension pieces 35 are respectively provided on the upper and lower sides of the inner plate 32. The three extension pieces 35 are locked and fixed on the wall surface 11 of the main bracket 10 by a third locking screw 36. The plurality of guide shafts 34 are used to guide the printing paper so that it can smoothly enter the gap between the rubber roller 31 and the print head module 43 for printing.

[0050] The TPH head assembly 40 has a hinged end 41 and a movable end 42. The movable end 42 is provided with a print head module 43. The hinged end 41 of the TPH head assembly 40 is hinged to the upper end of the rubber roller assembly 30 through a first hinge shaft 45 so that the print head module 43 of the movable end 42 can rotate around the first hinge shaft 45 toward or away from the rubber roller 31. The first hinge shaft 45 is detachably fixed to the wall surface 11 at the upper end of the rubber roller assembly 30.

[0051] In this embodiment, the TPH head piece group 40 includes a frame 44 and a print head module 43. The rear end of the frame 44 forms a rotating end. The first hinge shaft 45 is fixed to the main bracket 10 by screws and is located above the rubber roller group 30. The rotating end of the frame 44 is hinged to the first hinge shaft 45 and is fixed to the first hinge shaft 45 by a second limit screw 46, so that the frame 44 can rotate and swing around the first hinge shaft 45, and rotate in the direction close to or away from the rubber roller 31. When it rotates until the print head module 43 contacts the rubber roller 31, a printing gap for paper feeding is formed between the rubber roller 31 and the print head module 43. After the printing paper passes through the printing gap, the print head module 43 prints the corresponding content on it for output.

[0052] Therefore, during the process of installing or disassembling the TPH head piece group 40, it is only necessary to hinge the rotating end of the frame 44 to the first hinge shaft 45 through the second limit screw 46 after installing the first hinge shaft 45, and lock the second limit screw 46 to achieve the installation of the TPH head piece group 40. Conversely, the TPH head piece group 40 can be easily disassembled.

[0053] The movement cover assembly 50 has a paper outlet 51 facing the gap between the rubber roller 31 and the print head module 43 and a paper pickup optical coupler 57 for monitoring the paper pickup status;

[0054] In this embodiment, the movement cover group 50 includes a panel 52, a first connection edge 53 erected on the inner side wall of the panel 52, and two second connection edges 54. The first connection edge 53 is disposed on one side of the panel 52 close to the main body bracket 10, and the two second connection edges 54 are respectively disposed on the two sides close to and away from the main body bracket 10. The first connection edge 53 is locked and fixed to the main body bracket 10 through a second screw 531. A connection shaft 55 is provided at the lower end of the main body bracket 10 and located below the rubber roller group 30. The connection shaft 55 is rotatably connected to the two second connection edges 54. The paper outlet 51 is penetrated and provided on the panel 52. The paper pickup optocoupler 57 is disposed on the inner side wall of the panel 52 and the inner side wall of the paper outlet 51. Thus, the movement cover group 50 is preliminarily fixed through the first connection edge 53, and the fixing effect of the movement cover group 50 is further enhanced through the two second connection edges 54 and the connection shaft 55. In addition, in this embodiment, a first card slot (not shown in the figure) is provided around the circumferential surface of one end of the connection shaft 55 away from the main body bracket 10. The two second connection edges 54 are penetrated and provided with shaft holes (not shown in the figure) that are in clearance fit with the connection shaft 55. After the two second connection edges 54 are completely inserted into the connection shaft 55, a C-shaped snap spring 56 is snapped into the position of the first card slot, so that the panel 52 of the movement cover group 50 is completely limited on the connection shaft 55. The above structure enables the movement cover group 50 to be disassembled only by rotating the second screw 531 on the first connection edge 53 and operating the snap spring 56, without cumbersome operations.

[0055] The recycled paper group 60 has a rotatable paper collecting roller 61 for recycling printed release paper.

[0056] In this embodiment, the recycled paper group 60 includes a recycling base 62 locked and fixed to the main body bracket 10, a recycling shaft 63 perpendicular to the recycling base 62, and a paper collecting roller 61 rotatably sleeved on the outer peripheral side of the recycling shaft 63. A stopper is provided on the recycling shaft 63 for stopping the paper collecting roller 61.

[0057] Specifically, the recycling base 62 is in the shape of a flat disc and is locked and fixed to the main body bracket 10 through three third screws 64 arranged around its circumference. The recycling shaft 63 is rotatably connected to the central axis of the recycling base 62. The paper collecting roller 61 includes a recycling sleeve 611 sleeved outside the recycling shaft 63 and a covering sleeve 612 covering the upper end of the recycling base 62. The recycling sleeve 611 and the covering sleeve 612 are integrally provided and are limited and fixed on the recycling shaft 63 through a third limit screw. Three operation holes 613 corresponding to the positions of the third screws 64 are penetrated and provided on the covering sleeve 612. Thus, the recycling shaft 63 drives the paper collecting roller 61 to rotate as a whole, and when it is necessary to disassemble the recycled paper group 60 as a whole, it can be achieved only by disassembling the three third screws 64 through the three operation holes 613.

[0058] The sewing label optocoupler group 70 is disposed on the paper feeding path between the paper output roller 23 and the rubber roller 31 for monitoring the paper output state;

[0059] In this embodiment, the sewing label optocoupler group 70 includes a housing 71 detachably fixed to the main body bracket 10 and an optocoupler sensor 72. The housing 71 is provided with a paper feeding groove 73 along the printing paper transmission direction. The optocoupler sensor 72 is disposed on one side of the paper feeding groove 73 and is used for monitoring the state of the printing paper in the paper feeding groove 73.

[0060] The motor group 80 is detachably fixed with a driving motor for driving the rubber roller 31, the paper output roller 23, and the paper receiving roller 61;

[0061] In this embodiment, the output shaft of the driving motor penetrates out to the other side wall surface 11 of the main body bracket 10 and is fixedly connected with a driving gear 81. A plurality of driven gears 82 are rotatably provided on the wall surface 11 of the main body bracket 10. The rubber roller 31 and the paper receiving roller 61 are in transmission connection with the driving motor through the driven gears 82. Specifically, the rotating shaft of the rubber roller 31 penetrates out to the other side of the main body bracket 10, and the recovery shaft 63 also penetrates out to the other side of the main body bracket 10, and both are fixedly connected with the driven gears 82. A plurality of driven gears 82 are rotatably connected to the back of the main body bracket 10. The plurality of driven gears 82 are meshed and transmitted with each other and meshed with the driving gear 81. Thus, through the driving motor and the driving gear 81, the driving of the plurality of driven gears 82 can be realized, so that the rubber roller 31 and the paper receiving roller 61 rotate synchronously, and the transmission of the printing paper and the recovery of the back glue are realized in cooperation.

[0062] Among them, the paper roll fixing group 20, the rubber roller group 30, the TPH head piece group 40, the movement surface cover group 50, the recycled paper group 60, the sewing label optocoupler group 70, and the motor group 80 can all be detachably fixed to the same side wall surface 11 of the main body bracket 10.

[0063] Preferably, the rubber roller group 30 further includes a stripper 37. Both ends of the stripper 37 are respectively clamped between the inner side plate 32 and the outer side plate 33 and are located on one side of the rubber roller 31 for stripping the printing paper and its back glue.

[0064] Preferably, the side wall of the outer side plate 33 is provided with a connection hole 38. A connection piece 47 is detachably fixed to the side of the TPH head piece group 40 away from the main body bracket 10. The lower end of the connection piece 47 forms a connection end that can be snap-fitted with the connection hole 38.

[0065] In this embodiment, the connection piece 47 is locked and fixed to the side wall of the frame 44 through the fourth screw 48. The connection end at its lower end is concave in a U shape and can be inserted and matched with the connection hole 38.

[0066] Preferably, the upper end surface of the inner plate 32 is recessed downward to form an L-shaped limiting groove 39 , in which an easy-pull tab 391 is movably engaged, and the other end of the easy-pull tab 391 extends to the upper end of the rubber roller assembly 30 .

[0067] In this embodiment, the pull-tab 391 is bent in a V-shape as a whole, and the free end of its upper part forms a pull-tab portion 392 extending horizontally, and the lower end of the pull-tab 391 forms an L-shaped bending portion 393 adapted to the L-shaped limiting groove 39, and the middle part of the bending portion 393 is recessed downward to form a clamping portion 394 adapted to the upper and lower spacing of the limiting groove 39, thereby, the pull-tab 391 can be limited in the limiting groove 39 as a whole by the clamping portion 394, and when it is necessary to disassemble the rubber roller group 30, the rubber roller group 30 can be conveniently lifted up by the pull-tab 391, thereby facilitating the disassembly of the rubber roller group 30.

[0069] The beneficial effects of the utility model are as follows:

[0070] Printing modules on the market usually adopt a design method in which each part is fixed on the main frame 10. This method brings inconvenience to the assembly of the entire module during the production process, and the disassembly process is relatively complicated when the printer needs maintenance or fails. However, this design allows users to quickly replace parts by themselves when encountering difficulties in installation or disassembly.

[0071] The utility model proposes a modular design scheme, which makes each part into an independent component and allows these components to be independently locked on the main bracket 10. Although each component is locked independently, it is still related to each other, which does not affect the overall function and realizes simple disassembly and assembly operation. This improvement can effectively solve the problem of rapid installation and disassembly, especially when the printer needs maintenance or fails. In addition, the modular design also supports the shipment of parts, that is, the same components can be packed together, which helps to reduce transportation costs.

[0072] In summary, the utility model simplifies the disassembly and assembly process and significantly reduces the transportation and maintenance costs through the modularization of parts and components.

[0073] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
