DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In this embodiment, refer to Figure 1-3 A pressure-sensitive adhesive tape coating and printing device comprises a base 1, with a top mounting box 2 mounted on top of the base 1. The top mounting box 2 is mounted on the base 1 via support columns at the four corners of its bottom surface. A gluing station 3 and a printing station 4 are arranged adjacent to each other on the base 1. Conveyor rollers 5 for conveying the pressure-sensitive adhesive tape are located on either side of the gluing station 3 and the printing station 4. The pressure-sensitive adhesive tape is first printed with an anti-counterfeiting mark on the printing station 4 before being transferred to the gluing station 3 for gluing.

[0021] The top mounting box 2 is provided with a top cylinder 7 directly above the gluing platform 3. The output end of the top cylinder 7 is provided with a roller bracket, on which the gluing roller 6 is installed. The base 1 is provided with a bottom cylinder 14, which pushes the gluing platform 3 up and down through the pneumatic rod provided at its output end.

[0022] The top cylinder 7 is used in conjunction with the bottom cylinder 14 to adjust the gluing pressure of the gluing roller 6 on the pressure-sensitive adhesive tape and ensure uniform gluing.

[0023] As attached Figure 2 As shown, the top mounting box 2 is provided with a U-shaped upper mounting frame 8 and a lower mounting frame 11 just above the printing table 4, and the lower mounting frame 11 is elastically slidably connected to the bottom of the upper mounting frame 8. Specific description:

[0024] A guide rod 15 is provided at the top of the lower mounting frame 11. Slide holes for the guide rod 15 are provided on each arm of the upper mounting frame 8. The upper mounting frame 8 and the lower mounting frame 11 are connected by a return spring 18. The upper mounting frame 8 is fixed to the top mounting box 2, and the lower mounting frame 11 is slidably connected to the bottom of the upper mounting frame 8 and can slide up and down. The return spring 18 ensures that the lower mounting frame 11 automatically returns to its original position after any position change.

[0025] An eccentric wheel 16 is installed on the inner side of the upper mounting frame 8, a fixed wheel 17 is installed on the top of the lower mounting frame 11, and a printing roller 13 is installed on the inner side of the lower mounting frame 11. The upper eccentric wheel 16 pushes the lower fixed wheel 17 during rotation and causes the printing roller 13 to move downward and finally realize the printing operation on the surface of the pressure-sensitive tape.

[0026] Bevel gear assemblies 10 are respectively provided on both sides of the upper mounting frame 8 and the lower mounting frame 11. The upper and lower bevel gear assemblies 10 are kept in coaxial rotation through a linkage shaft 12. The bevel gear assemblies 10 on both sides of the upper mounting frame 8 and the lower mounting frame 11 are kept in linkage rotation through their respective synchronization shafts, wherein an eccentric wheel 16 is sleeved on the synchronization shaft of the upper mounting frame 8, and a printing roller 13 is sleeved on the synchronization shaft of the lower mounting frame 11.

[0027] The bevel gear assembly 10 comprises two meshing bevel gears. Using the upper mounting frame 8 as an example, the installation of one set of bevel gear assemblies 10 is illustrated: one bevel gear is attached to the side of the upper mounting frame 8, while the other is attached to an extension plate extending from the edge of the upper mounting frame 8. Finally, a motor 9 is mounted on one side of the upper mounting frame 8 to control the transmission of the bevel gear assembly 10. Driven by this motor 9, the bevel gear assemblies 10 on both sides, as well as the upper and lower bevel gear assemblies 10, maintain synchronized rotation.

[0028] As eccentric wheel 16 rotates, its protruding portion pushes fixed wheel 17 downward, bringing printing roller 13 closer to the pressure-sensitive adhesive tape on printing table 4. Printing roller 13 also rotates synchronously, allowing printing to proceed on the pressure-sensitive adhesive tape. Once printing is complete, the force exerted by eccentric wheel 16 on fixed wheel 17 dissipates, and return spring 18 lifts printing roller 13 off the pressure-sensitive adhesive tape. As eccentric wheel 16 continues to rotate, intermittent, uniform printing is achieved on the pressure-sensitive adhesive tape.

[0029] Finally, the table top of the printing table 4 is designed as a copy table top 19 for the printing roller 13 to press on. The copy table top 19 plays a supporting role, ensuring that the roller surface of the printing roller 13 is in full contact with the pressure-sensitive tape during the printing process, thereby improving the printing quality.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
