[0002] The film winder is a new type of mechanical equipment used in the plastic film industry. It is mainly used to wind the film material smoothly and wrinkle-free through a specific mechanical structure.

[0003] When existing film winders wind the film, since they only wind the film by rotating the winding shaft, the film is usually wound loosely, causing the wound film to easily fall apart. This not only affects subsequent packaging and other work, but also requires workers to spend a lot of time to organize the scattered film, greatly reducing work efficiency. Therefore, we propose a film winder. Utility Model Content

[0032] A specific application of this embodiment is:

[0033] When in use, first put the winding sleeve 115 on the winding shaft 11 so that the winding sleeve 115 contacts the positioning disk 111. At this time, the positioning shaft 4 on the winding sleeve 115 will be inserted into the positioning hole 3 on the positioning disk 111. Then, the winding shaft 11 is placed on the two placement blocks 112. At this time, the gear 113 on the winding shaft 11 will mesh with the gear 2 42. Then, push the limit rod 13. Since the square spring piece 341 is elastic, the limit rod 13 can be smoothly separated from the square spring piece 341, and the bottom of the limit rod 13 passes through the rotating shaft. The film is then wound around the winding sleeve 115 on the winding shaft 11, and the motor 41 is then started to drive the gear 2 42 to rotate clockwise, and the gear 2 42 drives the winding shaft 11 clockwise through the gear 1 13. The needle rotates, and the positioning disk 111 drives the winding sleeve 115 to rotate together through the positioning shaft 4, thereby winding the film. By turning the handle 252 to drive the threaded rod 251 to rotate, the lifting block 125 will move up or down, and the lifting block 125 will slide on the square limit bar 255. When the lifting block 125 moves, it will drive the push shaft 253 to move up or down. Since the push shaft 253 slides in the limit groove 123, it will drive the left side of the flip rod 122 to move up or down, and the right side of the flip rod 122 will move on the fixed block. 124 is rotated, and when the pressure rod 121 moves downward, it will cooperate with the auxiliary rod 2 to increase the tension of the film. When the pressure rod 121 moves upward, the tension of the film is reduced. When the winding is completed, the nut 322 is rotated counterclockwise to release the fixation of the limit rod 13, and then the limit rod 13 is pulled upward. The square spring piece 341 of the limit rod 13 is inserted, and the limit rod 13 is inserted into the fixed block 2 134 through the straight slot 131. At this time, the limit rod 13 is supported and limited, and the winding shaft 11 can be taken out, and then the winding sleeve 115 can be taken out.
