AI Technical Summary
In existing panel grinding equipment, linear guides are prone to ball blockage and jamming due to dust and rust in a water environment, affecting normal use.
The tensioning mechanism uses a slider that slides on a stainless steel guide post. The slider is driven by a drive component to slide on the guide post, which in turn moves the connecting post and the tensioning wheel to tighten or loosen the grinding belt, thus preventing the slider from clogging and rusting.
It effectively reduces slider clogging and rusting, avoids jamming problems in the ball bearing guide structure, and improves the efficiency and practicality of panel grinding.
