The utility model discloses a material-changing non-stop winding and unwinding device which comprises a middle
processing device, a winding device is arranged on one side of the middle
processing device, an unwinding device is arranged on the side, away from the winding device, of the middle
processing device, a winding control module is arranged on the winding device, and an unwinding control module is arranged on the unwinding device. A winding
assembly is arranged on the winding device, a
butt joint platform
assembly is arranged on the winding device and located above the winding
assembly, an unwinding assembly is arranged on the unwinding device, a
butt joint platform assembly is arranged on the unwinding device and located above the unwinding assembly, floating roller mechanisms are arranged on the winding device and the unwinding device, and film winding wheel sets are arranged at the top ends of the floating roller mechanisms. The winding and unwinding device is ingenious in structural design and stable in work and operation, buffering adjustment of a work piece can be carried out through the floating roller mechanism in the discharging replacement process and the receiving replacement process, the purposes that in the production process, a
machine is not stopped when materials are replaced, the middle manufacturing process is continuously operated are achieved, meanwhile, waste generated when the materials are in
butt joint is reduced, and the production efficiency is improved.
