After the slitting is completed, the unwinding shaft and the winding shaft can be rotated out for loading and unloading, making loading and unloading more convenient.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.
