Description
Technical Field
[0001] The utility model relates to the technical field of plastic film winding devices, and particularly relates to a plastic film winding device. Background Art
[0002] A winding device is a device used to wind a plastic film around a specific object or shaft during the production process of the plastic film.
[0003] When using a winder to wind and roll up a plastic film, in reality, one end of the plastic film is generally passed through a tension roller and then fixed to the winding roller with tape. Then, the motor is started to drive the groove roller and the winding roller to rotate to wind and store the plastic film, and it is fixed with tape. If the pulling force is too large when adjusting and pulling the tension before winding, the tape may fall off from the winding roller, so it needs to be fixed and adjusted again, which easily reduces the winding efficiency of the winder. At the same time, the adhesive on the tape is likely to stay on the winding roller and the plastic film, affecting the later use of the winding roller and the plastic film. Summary of the Utility Model

One side of one of the groove rollers is fixedly connected with a motor, and one side of the motor is fixedly connected with one side of the winder. A tension roller is rotatably connected to the inner wall of the winder. A fixing device is arranged on the outer surface of the winding roller. Limiting devices are arranged on both sides of the inner wall of the winder. The fixing device includes a clamping rod. A clamping groove is opened on the outer surface of the winding roller. The clamping rod is inserted into the inner wall of the clamping groove. Clamping hole blocks are symmetrically and fixedly connected to both sides of the winding roller. Slide holes are symmetrically opened on one side of both ends of the clamping rod. A spring is fixedly connected to the inner wall of the slide hole. One end of the spring is fixedly connected with a clamping block. The clamping block is slidably connected with the inner wall of the slide hole. One end of the clamping block is inserted into the inner wall of the clamping hole block.
[0006] The effects achieved by the above components are as follows: By setting the fixing device, when using a winding machine to wind and roll a plastic film, one end of the plastic film can be passed through the surface of the tension roller and placed on the inner wall of the card slot. Manually slide the two pairs of clamping blocks in the inner wall of the sliding hole in the opposite direction to a certain position, which drives the spring to contract.

Manually slide the two pairs of clamping blocks 26 in the inner wall of the sliding hole 24 in the opposite direction to a certain position, which drives the spring 25 to contract. Then press the clamping rod 23 against the plastic film and then snap it into the inner wall of the clamping groove 21.

Then when tensioning and pulling the plastic film to make it flat, one end will not fall off from the winding roller 8, improving the winding efficiency of the winding machine 1 and at the same time avoiding affecting the later use of the winding roller 8 and the plastic film. When winding, the motor 6 can be started to drive the groove roller 4 and the winding roller 8 to rotate to wind and store the plastic film.
[0029] Referring to Figure 2 and Figure 3 As shown in the figure, in this embodiment, a first telescopic rod 27 is fixedly connected to the inner wall of the sliding hole 24. One end of the first telescopic rod 27 is fixedly connected to one side of the clamping block 26. The outer surface of the first telescopic rod 27 is sleeved with the inner wall of the spring 25. By setting the first telescopic rod 27, it can play a role in supporting and strengthening the inner wall of the spring 25, making it not easily damaged during use and improving the service life of the spring 25. On both sides of the clamping rod 23, there are fixedly connected pulling blocks 28. The longitudinal section of the pulling block 28 is in a semi-circular arc shape.

By providing the limiting device 3, according to the width of the plastic film to be wound, manually hold the threaded rod 31 and rotate it spirally on one side of the winding machine 1 for a certain number of turns, and under the limiting action of the second telescopic rods 33, the limiting frame 32 can be driven to move to one end to a certain position, and both sides of the plastic film can be limited, so that when winding, the plastic film is not likely to shift and cause the wound plastic film roll to be wrinkled and distorted, improving the winding efficiency of the winding machine 1.
[0032] Referring to Figure 4 As shown in the figure, in this embodiment, rollers 34 are rotatably connected to the outer surfaces of both ends of the limiting frame 32, and the rollers 34 are made of rubber. By providing the rollers 34, when the limiting frame 32 limits both sides of the plastic film, the limit is more firm, it is not likely to fall off, and at the same time, the movement resistance of the plastic film is reduced. A bearing 35 is fixedly connected to the outer surface of one end of the threaded rod 31, and the outer ring of the bearing 35 is fixedly connected to one side of the limiting frame 32. By providing the bearing 35, the contact wear between the threaded rod 31 and the limiting frame 32 can be reduced, and the service life of both can be improved. A number of screwing blocks 36 are fixedly connected to one end of the threaded rod 31, and the number of screwing blocks 36 are arranged at equal distances. By providing the screwing blocks 36, the contact area of one end of the threaded rod 31 can be increased, which is convenient for manually holding and screwing it.
[0033] Working principle: When the winding machine 1 is used to wind and roll the plastic film, one end of the plastic film can be passed through the surface of the tension roller 7 and placed on the inner wall of the card slot 21. Manually slide the two pairs of clamping blocks 26 in the inner wall of the sliding hole 24 in the opposite direction to a certain position, which drives the spring 25 and the first telescopic rod 27 to contract. Then press the clamping rod 23 against the plastic film and snap it into the inner wall of the card slot 21. Then release the clamping block 26, and under the reset action of the spring 25 and the first telescopic rod 27, drive the clamping block 26 to slide outward in the inner wall of the sliding hole 24 to a certain distance, and one end snaps into the inner wall of the card hole block 22, limiting the clamping rod 23 in the inner wall of the card slot 21, so as to limit and fix one end of the plastic film. Then when the plastic film is tensioned and pulled to make it flat, one end will not fall off from the winding roller 8, improving the winding efficiency of the winding machine 1 and avoiding affecting the subsequent use of the winding roller 8 and the plastic film. When winding, the motor 6 can be started to drive the groove roller 4 and the winding roller 8 to rotate to wind and store the plastic film.
[0034] According to the width of the plastic film to be wound, manually hold the screwing block 36 and rotate the threaded rod 31 on one side of the winding machine 1 in a spiral manner for a certain number of turns. Under the limiting action of the second telescopic rod 33, the limiting frame 32 and the roller 34 can be driven to move to one end to a certain position, limiting both sides of the plastic film, so that it is not easy to shift during winding, resulting in the phenomenon of wrinkles and twists in the wound plastic film roll, and improving the winding efficiency of the winding machine 1.
