When disassembling and installing the winding roller, the shaft needs to be completely disassembled, and then the winding roller is sleeved on for rewinding and unwinding operations. However, safety accidents are likely to occur during disassembly, and frequent damage to parts such as the shaft head, airbag, and key is likely to occur after long-term use, resulting in a decrease in accuracy, and further affecting the unevenness of the rewound edge. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the existing technology and provide a rewinding and unwinding device for a film slitter.

The winding roller is fixed by the two short support shafts, and then the driving motor drives the winding roller to rotate, thereby realizing rewinding. When the rewinding is completed, only the first bracket and the second bracket need to be separated to remove the winding roller, without the need for overall disassembly.

[0012] An automatic deviation correction device is provided on the frame to improve the edge neatness during the winding and unwinding process.

[0013] The automatic deviation correction device includes a DF rotating roller frame provided on the moving box and a deviation correction sensor provided on the frame. A deviation correction controller is provided inside the control box. The deviation correction controller is connected to the deviation correction sensor and the DF rotating roller frame. The automatic deviation correction device is a prior art, and the deviation correction sensor can be an AE500 controller.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:
