[0006] To solve the above technical problems, the present invention adopts the following technical solution: A coating roller pressure adjustment mechanism includes two parallel wall plates connected to each other by a support roller. An outer sliding plate is installed on the inner side of each of the two wall plates, and an inner sliding plate is slidably installed on the inner side of the outer sliding plate via a first slide rail. A coating roller is rotatably mounted on the inner side of the outer sliding plate, and two paper guide rollers are mounted on the inner sliding plate. A first mounting base is installed on the outer sliding plate, and a second lead screw is vertically and rotatably mounted on the first mounting base. A nut block is fixed on the inner sliding plate, and the first lead screw and the nut block are threadedly engaged.
[0007] Furthermore, the coating roller is rotatably mounted on the lower end of the outer sliding plate, and the two paper guide rollers are placed on both sides of the inner sliding plate, with the two paper guide rollers located at the upper end of the coating roller, so that the two paper guide rollers and the coating roller are arranged in a triangle.
[0008] Furthermore, a drive shaft is rotatably mounted between the two outer sliding plates, a driving helical gear is fixed on the drive shaft, and a driven helical gear is fixed on the top of the second lead screw, with the driving helical gear meshing with the driven helical gear for transmission.
[0009] Furthermore, a second handwheel is installed at one end of the drive shaft.
[0010] Furthermore, the outer sliding plate is slidably mounted on the inner side of the wall panel via a second slide rail, and the outer sliding plate is driven by a driving device.
[0011] Furthermore, the driving device includes a cylinder, and the extension rod of the cylinder is connected to the outer sliding plate.
[0012] Furthermore, a second mounting base is installed on the inner side of the wall panel, and a second lead screw is rotatably mounted on the second mounting base. The lower end of the second lead screw is connected to the upper end of the cylinder by a thread, and a first handwheel is installed on the upper end of the second lead screw.
[0013] Furthermore, one of the wall panels has a vertically elongated hole, the drive shaft extends out of the elongated hole, and the second handwheel is installed at the outer end of the drive shaft.
[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: The cylinder can drive the inner and outer sliding plates to move up and down together, thereby realizing the rapid engagement and disengagement of the coating roller and the printing roller, and enabling quick and easy replacement of the coating roller, while also achieving uniform coating.
[0015] The first lead screw drives the inner sliding plate to move up and down through the nut block, thereby adjusting the distance between the two guide rollers and the coating roller. This allows for adjustment of the wrap angle of the conveyed paper on the coating roller, changing the pressure of the coating roller on the conveyed paper, and meeting the coating requirements of different materials, ensuring uniform coating.

Detailed Implementation
[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0020] like Figure 1-4 As shown, this utility model provides a coating roller pressure adjustment mechanism, including two parallel wall plates 1, which are connected to each other by a support roller 18. An outer sliding plate 5 is installed on the inner side of each of the two wall plates 1, and an inner sliding plate 4 is slidably installed on the inner side of the outer sliding plate 5 through a first slide rail 6. A coating roller 3 is rotatably mounted on the inner side of the outer sliding plate 5, and two paper guide rollers 2 are mounted on the inner sliding plate 4.
[0021] A first mounting base 19 is installed on the outer sliding plate 5, and a first lead screw 11 is vertically rotatably mounted on the first mounting base 19. A nut block 12 is fixed on the inner sliding plate 4, and the first lead screw 11 and the nut block 12 are threadedly engaged.
[0022] The coating roller 3 is rotatably mounted on the lower end of the outer sliding plate 5, and the two guide rollers 2 are placed on both sides of the inner sliding plate 4, with the two guide rollers 2 located at the upper end of the coating roller 3, so that the two guide rollers 2 and the coating roller 3 are arranged in a triangle.
[0023] When the first lead screw 11 rotates, it drives the inner sliding plate 4 to move up and down via the nut block 12, thereby adjusting the distance between the two guide rollers 2 and the coating roller 3. The paper 16 is conveyed along the path between the guide rollers 2 and the coating roller 3 as follows: Figure 4 As shown, when the two guide rollers 2 move downward, the wrap angle of the conveyed paper 16 on the coating roller 3 increases, changing the pressure of the coating roller 3 on the conveyed paper 16 to meet the coating requirements of different materials and achieve uniform coating.
[0024] A drive shaft 8 is rotatably mounted between the two outer sliding plates 5. A drive helical gear 9 is fixed on the drive shaft 8. A passive helical gear 10 is fixed on the top of the second lead screw 15. The drive helical gear 9 and the passive helical gear 10 mesh and transmit power.
[0025] A second handwheel 17 is installed at one end of the drive shaft 8. The second handwheel 17 is manually turned to drive the drive shaft 8 to rotate, thereby adjusting the inner sliding plate 4 to move up and down, which in turn drives the paper guide roller 2 to move up and down.
[0026] The outer sliding plate 5 is slidably installed on the inner side of the wall panel 1 via the second slide rail 7, and the outer sliding plate 5 is driven by a driving device.
[0027] The driving device includes a cylinder 13, and the telescopic rod of the cylinder 13 is connected to the outer sliding plate 5.
[0028] A second mounting base 102 is installed on the inner side of the wall panel 1. A second lead screw 15 is rotatably mounted on the second mounting base 102. The lower end of the second lead screw 15 is connected to the upper end of the cylinder 13 by a thread. A first handwheel 14 is installed on the upper end of the second lead screw 15.
[0029] One of the wall panels 1 has a vertically elongated hole 101, and the drive shaft 8 extends beyond the elongated hole 101. The second handwheel 17 is installed at the outer end of the drive shaft 8.
[0030] The specific working principle of this utility model: The cylinder 13 drives the inner sliding plate 4 and the outer sliding plate 5 to move up and down together, thereby achieving rapid engagement and disengagement of the coating roller and the printing roller (not shown in the figure). This also allows for quick and easy replacement of the coating roller, ensuring uniform coating. The height of the inner and outer sliding plates 4 and 5 can be finely adjusted using the first handwheel 14. Furthermore, the first lead screw 11 is threaded into the nut block 12. The coating roller 3 is rotatably mounted on the lower end of the outer sliding plate 5, and the two guide rollers 2 are positioned on either side of the inner sliding plate 4. The first lead screw 11, through the nut block 12, drives the inner sliding plate 4 to move up and down, thereby adjusting the distance between the two guide rollers 2 and the coating roller 3. This allows for adjustment of the wrap angle of the paper 16 on the coating roller 3, changing the pressure of the coating roller 3 on the paper 16, satisfying coating requirements for different materials, and ensuring uniform coating.
