Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing mechanism technology, and in particular to a high-efficiency paperboard printing roller adjustment device. Background Technology
[0002] In cardboard printing, paper thickness is not standardized; different batches or types of cardboard may vary in thickness. However, in many existing printing apparatuses, the printing rollers and frame are typically fixed using bolts or welding, resulting in fixed roller positions and difficulty in adjusting the spacing. When printing thick cardboard, the small spacing between the fixed rollers can easily cause paper jams; when printing thin cardboard, factors such as pressure may affect the printing quality. Therefore, a device that can adjust the roller spacing according to the cardboard thickness is needed.

Activating the second motor 17 rotates the threaded rod 18, driving the second slider 19. The second slider 19, equipped with blades and push blocks, cuts the cardboard and pushes it out of the operating table 1. Finally, activating the third motor 20 drives the take-up rod 21, causing the rack 22 to slide on the outer wall of the operating table 1, thus limiting and stabilizing the rack 22. The rack 22 drives the crossbar 23, which in turn drives the rotating rod 24. During rotation, the rotating rod 24 drives the second connecting rod 25, which in turn drives the second adjusting rod 26 to move on the inner wall of the conveyor table 27, thus limiting and stabilizing the second adjusting rod 26. Finally, the wound cardboard is pushed into the storage box.
