They are important equipment for packaging processing and molding. During long-term use, dirt will accumulate on the outer wall of the printing roller of the printing die-cutting machine, which will have a great impact on the printing quality.

[0003] The utility model with publication number CN213352623U discloses a die-cutting device for packaging printing, including a die-cutting device body, wherein pressure rollers are movably installed on the top and bottom of the inner side of the die-cutting device body, power boxes are fixedly embedded on both sides of the front side of the die-cutting device body, the bottom of the inner wall of the power box is fixedly connected to a transmission mechanism, the top of the front side of the power box is slidably connected to a sliding box, a connecting plate is provided on the inner side of the sliding box, a cleaning pad is fixedly connected to the back side of the connecting plate, both sides of the connecting plate pass through the interior of the sliding box, and both sides of the connecting plate are fixedly connected to a sliding cylinder located inside the sliding box, and the surface of the sliding cylinder is slidably connected to the inner wall of the sliding box.

[0004] However, the above patent has the following shortcomings:

[0005] 1. In the above patent, a transmission mechanism is used to drive the connecting plate and the cleaning pad on its surface to fit with the pressure roller.
