Moreover, the plastic film is inexpensive and easy to use, thus meeting market demands. During the production process of plastic film, a slitting device is required to wind the plastic film into a cylindrical shape for convenient subsequent use. However, the existing slitting devices on the market still have the following problems.

[0003] For example, in the prior art, a patent with the Chinese patent authorization number CN219859696U, application date: April 6, 2023, titled "A coiling device for plastic film production", relates to the technical field of plastic film production. It includes a box body, a coiling shaft, a connecting plate, an electrostatic elimination device, a first support plate, a second support plate, and a bracket. The lower surface of the box body is distributed with fixing plates, and the fixing plates are distributed with fixing holes. A coiling shaft is provided on one side of the box body, and the box body provides power for the coiling shaft. Below the coiling shaft is a connecting plate, on which an electrostatic elimination device, a first support plate, and a second support plate are provided. The bracket is arranged above the second support plate, and one end of the coiling shaft is arranged on the bracket; by setting an expandable airbag on the coiling shaft on the box body, it is convenient to fix the plastic film roll, keep the plastic film in a tightened state, and reduce the volume of the plastic film roll; by setting a push plate above the coiling shaft, it is convenient to unload the plastic film roll; by setting an electrostatic elimination device, it is convenient to eliminate the static electricity on both sides of the plastic film for convenient later use.

[0004] However, the above patent still has deficiencies. When winding the plastic film, it is not convenient to perform pretreatment, so that the wrinkles and dust on the plastic film are wound together, which easily causes problems with the winding quality of the plastic film due to wrinkles, and further reduces the operability of the winding device.

[0005] Therefore, we propose a coiling device for plastic films. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a coiling device for plastic film, which includes a winding frame 1. The inner wall of the winding frame 1 is rotatably connected with two mounting shafts 2 through bearings. The side wall of the winding frame 1 is connected to the end of one of the mounting shafts 2 through a driving part. The ends of the two mounting shafts 2 are provided with winding rollers 3. The inner wall of the winding frame 1 is fixedly connected with a fixed static electricity roller 4. The bottom of the fixed static electricity roller 4 is provided with an adjusting mechanism 5. The adjusting mechanism 5 includes a fixed rod 51 fixed on the side wall of the winding frame 1. The inner wall of the fixed rod 51 is threadedly connected with a connecting screw rod 52. The end of the connecting screw rod 52 is rotatably connected with a concave frame 53 through a bearing. The inner wall of the concave frame 53 is rotatably connected with a rolling static electricity roller 54 through a bearing. The rolling static electricity roller 54 is located directly below the fixed static electricity roller 4. By rotating the connecting screw rod 52 at the bottom of the fixed rod 51, the concave frame 53 can be adjusted up and down, so as to adjust the distance between the fixed static electricity roller 4 and the rolling static electricity roller 54, thereby rolling the plastic film surface, straightening the plastic film and removing dust, preventing wrinkles from affecting the subsequent winding quality.

[0024] According to Figure 2 it can be known that a bidirectional lead screw 6 is rotatably connected to the inside of the fixed static electricity roller 4 through a bearing. The surface of the bidirectional lead screw 6 is threadedly connected with a limiting rod 7. The limiting rod 7 is located directly in front of the rolling static electricity roller 54. By rotating the bidirectional lead screw 6, the limiting rod 7 can be displaced, so as to limit both sides of the plastic film according to the plastic film, preventing the plastic film from running off easily during winding.

[0025] According to Figure 2 it can be known that a guiding groove 8 is formed on the surface of the fixed static electricity roller 4. The guiding groove 8 is used to guide and limit the limiting rod 7. By providing the guiding groove 8, it is convenient to play a guiding and limiting role when the limiting rod 7 is displaced.

[0026] According to Figure 2 it can be known that both ends of the bidirectional lead screw 6 penetrate through the winding frame 1 and are fixedly connected with a turning handle 9. The surface of the turning handle 9 is provided with anti-slip lines. By providing the turning handle 9, it is convenient to control the rotation of the turning handle 9. At the same time, the anti-slip lines can increase the friction force of the hand.

[0027] According to Figure 3 it can be known that guide blocks 55 are fixedly connected to both sides of the concave frame 53. The guide blocks 55 slide on the side wall of the winding frame 1. With the arrangement of the guide blocks 55, it can play a guiding and limiting role when the concave frame 53 is displaced.

[0028] According to Figure 4It can be seen that an installation block 10 is fixedly connected to the end of the installation shaft 2, connection blocks 11 are fixedly connected to both sides of the winding roller 3, and an installation pin 12 penetrates through the interiors of the installation block 10 and the connection blocks 11. With the setting of the installation pin 12, the installation pin 12 can be inserted into the interiors of the installation block 10 and the connection blocks 11, thereby connecting and installing the installation shaft 2 and the winding roller 3, and at the same time facilitating the later disassembly and replacement of the winding roller 3 with the same winding roller 3 to wind a new plastic film.

[0029] The working principle of the present utility model: When in use, first pass the end of the plastic film through between the fixed static roller 4 and the adjustment mechanism 5, and then connect and fix it to the surface of the winding roller 3. At this time, rotate through the driving part on the side wall of the winding frame 1, so that it can drive the installation shaft 2 to rotate. When the installation shaft 2 rotates, the winding roller 3 can be rotated synchronously. When the winding roller 3 rotates, the plastic film can be wound. Through the drive of the adjustment mechanism 5, the surface of the plastic film can be straightened and dust can be removed. By rotating the screw 52 connected to the bottom of the fixed rod 51, the concave frame 53 can be adjusted up and down, thereby adjusting the distance between the fixed static roller 4 and the rolling static roller 54, so as to roll-press the surface of the plastic film, so that the plastic film can be straightened and the dust can be removed, preventing wrinkles from affecting the subsequent winding quality.
