[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides an adjustable-angle PVC film traction and guiding device, including a main frame 1. Slide grooves 13 are provided on both sides of the inner cavity of the main frame 1. A limit post 12 is fixedly connected inside one slide groove 13, and a first servo motor 3 is fixedly connected to the top of the main frame 1 on one side of the other slide groove 13. A screw 16 is fixedly connected to the output shaft of the first servo motor 3. A square block 4 is slidably sleeved on one slide groove 13, and another square block 4 is threadedly sleeved on the outer surface of the other slide groove 13. Equipment boxes 5 are fixedly connected to the bottom of both square blocks 4. A second servo motor 6 is fixedly connected to one side of one equipment box 5, and a connecting shaft 7 is fixedly connected to the output shaft of the second servo motor 6. Furthermore, a gear 14 is fixedly sleeved at both ends of the connecting shaft 7, and a first traction roller 8 is rotatably connected between the two equipment boxes 5. Each end of the first traction roller 8 is provided with a roller shaft 11, and the two roller shafts 11 are rotatably connected to adjacent sides of the two equipment boxes 5. A second rotating shaft 17 is rotatably connected to one side of the inner cavity of each of the two equipment boxes 5, and another gear 14 is fixedly sleeved on the outer surface of each of the two second rotating shafts 17. The two gears 14 mesh inside the equipment box 5 on the same side, and a rotating block 15 is fixedly connected to the other end of each of the two second rotating shafts 17. A second traction roller 9 is rotatably connected between the two rotating blocks 15, according to production requirements. The thickness of the PVC film can be adjusted by changing the length of the rotating block 15 to control the distance between the first traction roller 8 and the second traction roller 9. This solution focuses on adjusting the traction angle. Therefore, once the distance between the first traction roller 8 and the second traction roller 9 is set appropriately, the first servo motor 3 can be activated, and the vertical sliding of the two square blocks 4 can be used to adjust the overall height of the first traction roller 8 and the second traction roller 9, thus adjusting the angle of the PVC film in the vertical direction. On the other hand, after activating the second servo motor 6, the connecting shaft 7 at one end of each of the two equipment boxes 5 will rotate using the rotation of two gears 14, which in turn drives two other gears 14 to rotate. At this time, the two second rotating shafts 17 can drive the two rotating blocks... 15 rotates, causing the second traction roller 9 to move circumferentially along the axis of the first traction roller 8, thereby achieving circumferential angle adjustment. Using the above adjustment methods, the traction angle of the PVC film can be adjusted. Among the above adjustment methods, the vertical adjustment is suitable for large angle adjustments of ±30° to ±60°, which is particularly suitable for applications that require significant changes in the film conveying direction. The circumferential square adjustment is suitable for medium and high speed film conveying, and is suitable for high-precision scenarios such as printing and coating. The angle adjustment range is usually between ±15° and ±45°, which is suitable for most film guiding adjustment needs. Thus, the device can adapt to different needs in terms of adjustment requirements, and the device is highly practical.

[0021] To improve the stability of the two square blocks 4 sliding inside the two slide grooves 13, the two square blocks 4 are respectively slidably disposed inside the two slide grooves 13, and the two sides of the two square blocks 4 are respectively attached to the two sides of the inner cavity of the two slide grooves 13.

[0022] To facilitate the fixing of the device on the production line, connecting plates 2 are fixed to both sides of the bottom of the main frame 1, and mounting holes are opened on the outer surface of both connecting plates 2.

[0023] In order to utilize the connecting shaft 7 to achieve the rotational adjustment of the second traction roller 9 without interfering with the film traction operation of the first traction roller 8 and the second traction roller 9, the connecting shaft 7 is rotatably positioned directly above the first traction roller 8, and a gap is provided between the connecting shaft 7 and the first traction roller 8.

[0024] Furthermore, in order to better adjust the angle of the second traction roller 9 in the circumferential direction, the second traction roller 9 is rotatably positioned below the two equipment boxes 5, and a gap is provided between the second traction roller 9 and the two equipment boxes 5.

[0025] In order to provide support and adjustment space for the installation of the first traction roller 8 and the second traction roller 9, the main frame 1 is U-shaped, and the first traction roller 8 and the second traction roller 9 are both movably connected inside the U-shaped opening of the main frame 1.

In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
