[0036] Working principle: first start the motor 3, drive the winding roller 4 to rotate through the supporting plate 2. The rotation of the winding roller 4 makes the polyethylene film quickly wind in. In the winding process, the height is adjusted through the cooperation of the sliding rod 8 and the sliding block 9 to adapt to the film material of different heights. When the film material passes through the winding roller 4, the motor 3 drives at the same time, and the supporting block 5 provides stable support, so that the rotating column 6 rotates smoothly in it, and then drives the movement of the connecting block 7. The rotation of the connecting block 7 drives the sliding rod 8 to move up and down. The combination between the sliding rod 8 and the sliding block 9 makes the sliding block 9 slide freely along its path, which can place the polyethylene film of different widths on both sides. At this time, the upper pressing block 10 and the lower pressing block 12 are closely connected through the slide rod 11, which ensures the positioning stability of the film material in the winding process. The setting of the auxiliary sliding roller 13 can prevent the film material from shifting left and right in the winding process. The combination of the upper pressing block 10 and the lower pressing block 12 can be close in time to ensure that the film material slides smoothly between the two auxiliary sliding rollers 13. The polyethylene film maintains good tension and stability in the winding process, which improves the efficiency and quality of winding;

[0037] When the polyethylene film is pulled with different tension, the cylinder 22 is started, after the cylinder 22 is lifted, the top block 23 will be lifted, and then drive the connecting rod 18 to change the angle. The two connecting blocks 16 connected by the connecting rod 18 realize the adjustment of the position through the through slot 15. With the inclination of the connecting rod 18, the connecting block 16 slides up and down in the through slot 15 of the vertical plate 14, and the butt block 17 behind the connecting block 16 also moves. The tension roller 24 fixedly connected on the adjacent side of the butt block 17 plays a role in adjusting and maintaining the tension of the polyethylene film in the process, ensuring that the film material will not appear loose or wrinkle when winding. The movable column 20 as the support of the connecting rod 18 can prevent the connecting rod 18 from deviating in the working process, and ensure the accuracy of winding. The vertical rod 19 provides stable support for the movable column 20, making the whole operation more reliable. The height adjustment of the cylinder 22 makes the connecting rod 18 be able to flexibly control the angle, realize the accurate winding of the film material and make the tension.
