The traction rod 26 is arranged along the length direction of the active roller 18. The initial position of the traction rod 26 is between the active roller 18 and the second cutting device 22. After rotating, it passes over the receiving roller 16. One end of the active roller 18 is connected to a driving device 28. A clamping device 30 is arranged on the top of the receiving roller 16. The clamping device 30 includes a clamping roller 32 and a cylinder 34 arranged at both ends of the clamping roller 32 and driving the clamping roller 32 to move up and down, so that the clamping roller 32 abuts against the receiving roller 16 to improve the winding effect.
