Since the end of the tensioning roller 6 is connected to the connecting block 7, and the connecting block 7 is connected through the bearing bar 13 connected to the U-shaped tooth plate 9, the tensioning rollers 6 can move synchronously, so as to tighten the wound shrink film, thereby preventing wrinkles from occurring during the winding process.

[0023] Please refer to Figure 1 and Figure 3, a cutting and positioning mechanism 3 is arranged inside the winding main body 1. The cutting and positioning mechanism 3 includes a cutting platform 14, positioning rollers 15, electric telescopic rods 20 and a cutting knife 22. The lower end of the cutting platform 14 is fixedly connected to the inner bottom of the winding main body 1. Installation grooves 16 are formed on both sides of the upper surface of the cutting platform 14. The outer surface of the end of the positioning roller 15 is movably connected to the inside of the installation groove 16. A U-shaped positioning plate 17 is clamped inside the installation groove 16. The U-shaped positioning plate 17 is connected to the upper surface of the cutting platform 14 by bolts 18.

At this time, the ends of the two groups of positioning rollers 15 are placed inside the installation grooves 16 and are clamped by the U-shaped positioning plates 17, so as to position the positioning rollers 15 and prevent the shrink film from being stably output during the winding process. When the winding reaches a certain degree, the electric telescopic rod 20 works to drive the cutting knife 22 to move downward, thereby cutting the shrink film.

[0024] Please refer to Figure 2 , there are two groups of tension rollers 6, and the two groups of tension rollers 6 are symmetrically arranged with respect to the midline of the notch 5.
