AI Technical Summary
In the current printing press, during the feeding process, it is difficult to center the printing paper roll with the feeding roller, and it is easy to spread out, causing feeding deviation. There is a lack of effective material blocking structure.
A material blocking structure for a printing press was designed, including a side frame, a material roller, and a material blocking mechanism. Through the combination of a threaded rod, a slide block, and a material blocking arm, the material roll is centered and positioned to prevent deviation. The threaded rod drives the slide block to move and clamp the material roll, ensuring that it is centered and aligned on the material roller and preventing it from spreading out.
It achieves precise positioning of the printed paper roll and prevents deviation during the feeding process, improving the accuracy and efficiency of feeding and avoiding the problems of manual alignment and scattering.
