[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Example 1

[0025] This utility model provides, for example Figures 1-5 As shown, a double-sided adhesive coating device for plastic protective film includes: a support platform 1, an adhesive coating device 2 disposed on the surface of the support platform 1, a vertical plate 3 disposed on the surface of the support platform 1, a positioning bearing 4 disposed inside the vertical plate 3, and a traction roller 5 inserted into the inner circumference of the positioning bearing 4; a mounting plate 6, a moving groove 7 opened on the side of the mounting plate 6, a moving plate 8 inserted into the moving groove 7, a first bearing 9 disposed inside the moving plate 8, and an auxiliary roller 10 inserted into the inner circumference of the first bearing 9; and a support plate 11, a cleaning frame 12 disposed on the inner side of the support plate 11, the cleaning frame 12 having rounded corners 13 on its side, and brush bristles 14 disposed on the inner surface of the cleaning frame 12.

[0026] When it is necessary to apply adhesive to the surface of the plastic protective film, the plastic protective film can first be pulled and tensioned by the cooperation of the traction roller 5 and the auxiliary roller 10. Then, it is convenient to apply adhesive to both sides of the plastic protective film using the adhesive application equipment 2. When guiding the plastic protective film, the plastic protective film passes through the cleaning frame 12, so that the brush 14 set inside the cleaning frame 12 can clean the upper and lower sides of the plastic protective film, thereby avoiding the problem of foreign particles adhering to the upper and lower sides of the plastic protective film.

[0027] Example 2: Figure 1 and Figure 2As shown, a cleaning frame 12 is provided to facilitate cleaning of the upper and lower surfaces of the plastic protective cotton. The traction roller 5 is fixedly connected to the inner ring surface of the positioning bearing 4. The upright plate 3 is fixedly connected to the side of the support platform 1 by positioning bolts. The mounting plate 6 is fixedly connected to the side of the support platform 1 by fixing bolts. There are two sets of mounting plates 6, which are symmetrically distributed about the support platform 1. The cleaning frame 12 is fixedly connected to the inner side of the support plate 11 by bolts. The upper and lower surfaces of the cleaning frame 12 are provided with bristles 14.

[0028] More specifically, while cleaning the plastic protective film, the auxiliary roller 10 and the traction roller 5 can be used to guide and tension the plastic protective film. The rounded corners 13 on the side of the cleaning frame 12 can reduce the friction on the surface of the plastic protective film. Then, the brush bristles 14 can be used to clean the surface of the plastic protective film.

[0029] To facilitate the adjustment of the cleaning frame 12 angle according to the height of the auxiliary roller 10, a support plate 11 is provided. A support rod 20 is provided on the side of the moving plate 8. A positioning ring 21 and a support plate 11 are sleeved on the surface of the support rod 20. The positioning ring 21 is fixedly connected to the surface of the support rod 20. The surface of the support rod 20 is threaded, and a positioning nut 23 is screwed onto the thread. The support plate 11 is rotatably connected to the support rod 20.

[0030] When it is necessary to adjust the angle of the cleaning frame 12 during use, the positioning nut 23 can be loosened first, so that the support plate 11 can be rotated to adjust the angle of the cleaning frame 12. After the cleaning frame 12 is adjusted to a suitable angle, the positioning nut 23 can be tightened with the positioning ring 21 to fix the support plate 11, and then the cleaning frame 12 can be used.

[0031] Example 3: Figures 3-5 As shown, a positioning rod 18 is provided to facilitate height adjustment of the auxiliary roller 10. A positioning hole 15 is provided on the side of the moving groove 7. Multiple sets of positioning holes 15 are provided and are arranged linearly at equal intervals on the side of the moving groove 7. A base plate 16 is provided on the side of the moving plate 8. A positioning port 17 is provided on the side of the base plate 16. The positioning rod 18 is inserted into the positioning port 17. One end of the positioning rod 18 is inserted into the positioning hole 15. A pull plate 19 is provided at the other end of the positioning rod 18. A support spring 22 is provided in the moving groove 7. One end of the support spring 22 is fixedly connected to the bottom of the moving groove 7, and the other end of the support spring 22 is fixedly connected to the bottom of the base plate 16.

[0032] More specifically, when the height of the auxiliary roller 10 needs to be adjusted, the pull plate 19 can be pulled first to pull the positioning rod 18 out of the positioning hole 15. Then, the moving plate 8 can be easily pulled up and down. The support spring 22 prevents the moving plate 8 from moving directly down after the positioning rod 18 is pulled out of the positioning hole 15. The elasticity of the support spring 22 can be used to support the moving plate 8, making it convenient for the staff to adjust the moving plate 8. After the moving plate 8 is pulled to the appropriate position, the positioning rod 18 can be inserted into the positioning hole 15 of another group for fixing. Thus, the height of the auxiliary roller 10 can be adjusted, and the tension of the plastic protective film can be adjusted.
