The first hydraulic cylinder 22 is mounted on the first support plate 11, and its output end is connected to the side wall of the second support plate 21. The first hydraulic cylinder 22 is used to push the second support plate 21, adjust the position of the support roller 271, tighten the plastic film, and prevent wrinkles from occurring during winding. The guide rod 23 is also installed on the side wall of the second support plate 21. The guide rod 23 is used to support the second support plate 21 and guide its movement. The guide rod 23 is slidably connected to the first support plate 11. The support assembly 28 is mounted on... At the upper end of the base 1, a groove 24 is provided on the inner wall of the second support plate 21. The groove 24 facilitates the alignment and insertion of the connecting seat 27. A turntable 25 is rotatably installed on the inner side of the groove 24. A reduction motor 26 is installed on the back of the second support plate 21 by bolts. The output end of the reduction motor 26 is connected to the turntable 25. The reduction motor 26 drives the turntable 25 to rotate. The turntable 25 drives the connecting seat 27 to rotate. The connecting seat 27 is installed on the turntable 25 by bolts. A support roller 271 is installed on the connecting seat 27. The connecting seat 27 drives the support roller 271 to rotate and roll up the plastic film. A connector 272 is rotatably installed on the other end of the support roller 271. The connector 272 is used to support the other end of the support roller 271 and increase the stability of the support roller 271 when it rotates and rolls up the plastic film.

[0024] Furthermore, a groove 291 is provided at the upper end of the base 1. The groove 291 is used to guide the sliding of the support frame 281. The support assembly 28 includes the support frame 281, the first connecting block 282, and the second connecting block 283. The bottom of the support frame 281 is slidably disposed in the groove 291. The sliding of the support frame 281 is used to change the position of the first connecting block 282, so as to facilitate the separation of the first connecting block 282 from the connector 272. The first connecting block 282 and the second connecting block 283 are respectively fixedly installed on the support frame 281. The first connecting block 282 is used to connect to the connector 272, and the second connecting block 283 is used to connect and support the screw 32. A bolt is provided at the top of the first connecting block 282. The connector 272 is inserted into the first connecting block 282 and connected by the bolt. This not only positions the connector 272 but also does not affect the rotation of the support roller 271. A second hydraulic cylinder 29 is installed at the rear end of the base 1. The output end of the second hydraulic cylinder 29 is connected to the support frame 281. The second hydraulic cylinder 29 is used to push and pull the support frame 281 to move its position.

[0025] Furthermore, the limiting mechanism 3 includes a support base 31, a screw 32, a first limiting plate 33, and a second limiting plate 34. The support base 31 is bolted to the second support plate 21, and its installation position on the second support plate 21 is variable. The support base 31 supports the screw 32 for easy installation and removal. The first limiting plate 33 and the second limiting plate 34 are respectively inserted into the screw 32, which supports the first limiting plate 33 and the second limiting plate 34. One end of the screw 32 is threadedly connected to the support base 31. The other end of the rod 32 is inserted into the second connecting block 283.

By rotating the corresponding first flange nut 35 and the second flange nut 36, the position of the first limiting plate 33 and the second limiting plate 34 are adjusted respectively. The first limiting plate 33 and the second limiting plate 34 limit and rewind the plastic film wound on the support roller 271 to prevent wrinkles from occurring during winding.

[0026] The working principle of this utility model is as follows: The connecting seat 27 is aligned and inserted into the groove 24, and connected to the turntable 25 by bolts. The cut plastic film is introduced onto the support roller 271. The first hydraulic cylinder 22 pushes the second support plate 21. The worker controls the movement position of the support roller 271 and monitors the tension of the plastic film to allow the tension of the plastic film to be slightly loosened, avoiding the plastic film from being too tight and damaging the tension. The second hydraulic cylinder 29 pushes the support frame 281, so that the connector 272 at one end of the support roller 271 is inserted into the first connecting block 282 and connected by bolts. This not only positions and supports the connector 272, but also does not affect the rotation of the support roller 271. The support seat 31 is installed on the second support plate 21 by bolts. One end of the screw 32 is first inserted into the first connecting block 282. Inside the second connecting block 283, the other end is threaded to the support base 31 and tightened. Rotate the corresponding first flange nut 35 and second flange nut 36 to adjust the position of the first limiting plate 33 and the second limiting plate 34 respectively. The first limiting plate 33 and the second limiting plate 34 limit the plastic film being wound on the support roller 271 to prevent wrinkles from forming during winding. When removing the plastic film, first rotate the screw 32 to disengage from the support base 31, and then disengage the other end of the screw 32 from the second connecting block 283. Remove the bolts between the joint 272 and the first connecting block 282. The first hydraulic cylinder 22 continues to push the second support plate 21 to disengage the joint 272 from the first connecting block 282, making it easier to remove the plastic film and the support roller 271.

[0027] In summary, by setting up an adjustable plastic film winding device, the position of the support roller is adjusted before the plastic film is wound up, and the plastic film is tightened and adjusted without damaging the plastic film tension, thereby preventing wrinkles from appearing in the subsequent winding process; by setting up a limiting mechanism, the plastic film wound on the support roller is limited during winding, preventing wrinkles from appearing during winding.
