Description

When the plate is bent, the end of the plate against the blocking plate in the material blocking mechanism will be raised upward. Since the plate and the blocking plate abut against each other, the force of the plate against the plate raised upward will act on the blocking plate, making the end of the blocking plate in contact with the plate have a tendency to go upward. Since the blocking plate is fixed by bolts, the long-term use will cause the bolt connection of the blocking plate to be loose or the connection between the blocking plate and the material blocking mechanism to be deformed, affecting the normal use of the material blocking mechanism.
