[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0023] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments.

[0024] Embodiment

[0025] Refer to Figures 1-4 , which is the first embodiment of the present utility model. This embodiment provides a coiling structure for plastic film production, including a frame 1, a coiling mechanism 2, and a cutting mechanism 3. The coiling mechanism 2 is fixedly installed at the top of the frame 1, and the cutting mechanism 3 is fixedly installed at the top of the coiling mechanism 2. The coiling mechanism 2 includes a first motor 201, a rotating shaft 202, a positioning disk 203, a winding roller 204, a second motor 205, a positioning plate 206, and a movable plate 207. The first motor 201 is fixedly installed on the left side of the frame 1, the rotating shaft 202 is fixedly installed at the output end of the first motor 201, the positioning disk 203 is fixedly installed at the right end of the rotating shaft 202, a plurality of winding rollers 204 are fixedly installed on the right side of the positioning disk 203, the second motor 205 is fixedly installed at the left end of the winding roller 204, and the positioning plate 206 is fixedly installed on the winding roller 204.

[0026] Specifically, the movable plate 207 is slidably connected to the winding roller 204.

[0027] Furthermore, through the combined use of the movable plate 207 and the positioning plate 206, it is convenient to effectively reduce the friction between the plastic film and the winding roller 204 during the winding process, thereby reducing the occurrence of poor coiling.

[0028] Specifically, a supporting roller 4 is fixedly installed on the front surface of the positioning disk 203. Support frames 5 are fixedly installed on both the left and right sides of the supporting roller 4, and a hydraulic cylinder 6 is fixedly installed at the bottom of the support frame 5. The supporting roller 4 is arranged parallel to the winding roller 204.

[0029] Furthermore, through the setting of the supporting roller 4, it is convenient to support the plastic film during the winding process, making the tension of the plastic film more stable.

[0030] Specifically, the cutting mechanism 3 includes a cutting blade 301, an electric telescopic rod 302, a linear motor 303, and a slide rail 304. The cutting blade 301 is fixedly installed on the top of the winding mechanism 2. The electric telescopic rod 302 is fixedly installed on the top of the cutting blade 301. The linear motor 303 is fixedly installed on the top of the electric telescopic rod 302. The slide rail 304 is fixedly installed on the top of the linear motor 303.

[0031] Furthermore, through the combined use of the electric telescopic rod 302, the linear motor 303, and the slide rail 304, the position of the cutting blade 301 can be freely adjusted, facilitating the cutting of the wound plastic film and making the use more convenient.

[0032] Specifically, support legs 7 are fixedly installed at the bottom of the frame 1, and rubber pads 8 are fixedly installed at the bottoms of the support legs 7.

[0033] Furthermore, through the setting of the rubber pads 8, the running stability of the winding structure is improved, the noise is reduced, and the impact on the environment is decreased.

[0034] During use, the paper tube is sleeved on the winding roller 204, and the paper tube is fixed by the positioning plate 206 and the movable plate 207. The winding roller 204 is driven to rotate by the second motor 205 to complete the winding of the plastic film. After the winding is completed, the rotating shaft 202 is driven to rotate by the first motor 201. The rotating shaft 202 drives the positioning disk 203 to rotate, changing the position of the winding roller 204 and making the plastic film closely adhere to the next winding roller 204. Then, the linear motor 303 and the electric telescopic rod 302 are started, and the cutting blade 301 is used to cut the part of the plastic film that has been wound. After that, the winding work of the next winding roller 204 is carried out.

[0035] In summary, through the combined use of multiple winding rollers 204 and the movable plate 207, the tension can be made more stable during the continuous rewinding of the plastic film and the production without stopping, the winding accuracy is improved, thereby simplifying the operation process, increasing the production efficiency and production automation, reducing the structure preparation time, and at the same time solving the problem of low production efficiency of a single winding roller 204.
