[0002] The printing plate roller is a vital component of the printing equipment, responsible for evenly transferring the ink to the printing medium. It is a key link in the printing process and directly affects the printing quality and efficiency. In the traditional printing process, the ink takes a long time to dry completely, which will limit the printing speed. In order to significantly shorten the drying time of the ink and make the printing process faster and more continuous, a quick-drying printing plate roller assembly is needed.

[0003] During the use of the traditional quick-drying printing press plate roller assembly, the ink is evenly transferred to the printing medium through the plate roller.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0031] Specifically, first, in order to adjust the contact pressure between the pressure roller 11 and the printing roller 3, the output end of the electric push rod 8 extends out, driving the cross bar 9 to move smoothly, thereby applying an extrusion force to the first spring 10. As the electric push rod 8 is pushed, the first spring 10 produces corresponding pressure changes during its deformation process. This adjustment enables the pressure of the pressure roller 11 on the printing roller 3 to be accurately controlled. During its operation, the pressure roller 11 slides stably through the limiting groove 5 and is tightly connected to the connecting block 7. The connecting block 7 is precisely limited in the fixed frame 4 by the limiting column 6 to ensure that the entire system maintains stability during the adjustment process. Through this fine adjustment mechanism, the pressure of the pressure roller 11 can be accurately controlled to optimize the printing effect and ensure the consistency and reliability of the printing quality.

[0032] Reference Figure 3 , the other side of the support plate 1 is fixedly connected to a support plate 2 12, the top of the support plate 2 12 is rotatably connected to a connecting rod 13, one end of the connecting rod 13 is fixedly connected to a bracket 14, a cleaning roller 15 is rotatably connected inside the bracket 14, the outer wall of the cleaning roller 15 is attached to the outer wall of the pressure roller 11, the top of the support plate 2 12 is rotatably connected to a fixed block 16, one side of the fixed block 16 is fixedly connected to a telescopic rod 18, one end of the telescopic rod 18 is fixedly connected to a fixed block 2 17, the outer wall of the fixed block 2 17 is rotatably connected to the bottom of the bracket 14, the outer wall of the telescopic rod 18 is sleeved with a second spring 19, one end of the second spring 19 is fixedly connected to the bottom of the fixed block 2 17, and the other end of the second spring 19 is fixedly connected to the top of the fixed block 16;

[0033] Specifically, subsequently, during the operation of the pressure roller 11, the pressure roller 11 is continuously cleaned through contact with the cleaning roller 15. The cleaning roller 15 is stably limited under the support of the bracket 14, so that it maintains a precise position during the entire cleaning process. The bracket 14 is tightly connected to the support plate 2 12 through the connecting rod 13 to ensure the stability of the cleaning roller 15 during operation. The other side of the bracket 14 is precisely matched with the fixing block 1 16 through the fixing block 2 17 and is connected to the telescopic rod 18. This design allows for appropriate adjustment and position adjustment of the cleaning roller 15. Through the tension support of the second spring 19, the cleaning roller 15 can always fit tightly against the outer wall of the pressure roller 11, ensuring that during the operation of the pressure roller 11, the cleaning roller 15 effectively removes attached ink and impurities, keeps the pressure roller 11 clean, and thereby ensures the consistency and stability of printing quality.

[0034] Working principle: When using the quick-drying printing press plate roller assembly, first, when it is necessary to adjust the pressure of the pressure roller 11 contacting the printing roller 3, the output end of the electric push rod 8 extends to drive the cross bar 9 to move and squeeze the first spring 10, and the pressure of the pressure roller 11 on the printing roller 3 is adjusted by controlling the deformation degree of the first spring 10. The pressure roller 11 slides in the limiting groove 5 and is connected to the connecting block 7. The connecting block 7 and the cross bar 9 are limited inside the fixed frame 4 by the limiting column 6. Then, when the pressure roller 11 is running, the pressure roller 11 is continuously cleaned by contact with the cleaning roller 15. The cleaning roller 15 is limited by the bracket 14 and is connected to the support plate 2 12 through the connecting rod 13. The other side of the bracket 14 is connected to the telescopic rod 18 through the cooperation of the fixed block 2 17 and the fixed block 1 16, and the cleaning roller 15 is always attached to the outer wall of the pressure roller 11 through the tension support of the second spring 19.
