Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a high-transparency and high-brightness sheet surface treatment device, including a housing 1, with inlet and outlet slots 2 on both sides of the housing 1, and a tensioning device 8 installed inside the housing 1. The tensioning device 8 includes two movable slots 802, and two movable blocks 805 are respectively opened on both sides of the inner wall of the housing 1. A movable block 805 is slidably connected inside the movable block 805, and a connecting frame 807 is connected between the two movable blocks 805. A guide wheel 806 is rotatably connected between the inner walls of the connecting frame 807. The movable block 805 is embedded with a sliding sleeve, and a limit rod 803 is slidably connected inside the sliding sleeve. A second spring 804 is sleeved on the outer wall of the limit rod 803. The two ends of the limit rod 803 are respectively connected to the two sides of the inner wall of the movable groove 802. The two ends of the second spring 804 are respectively connected to one side of the movable groove 802 and one side of the movable block 805. Sliding grooves 801 are opened on both sides of the inner wall of the movable groove 802, and a sliding block 808 is slidably connected inside the sliding groove 801. One side of the sliding block 808 is connected to one side of the movable block 805.

[0027] In a specific implementation, by setting a tensioning device 8, the PVC film passes through the bottom of the guide wheel 806, and then the elastic force of the second spring 804 drives the moving block 805 to move downward. By setting a sliding block 808 to slide in the sliding groove 801, the sliding block 808 drives the moving block 805 to move more stably. Furthermore, by setting a limiting rod 803 to support the moving block 805, the moving block 805 provides good support for the connecting frame 807, thereby further improving the stability of the device. Then, the moving block 805 drives the connecting frame 807 to move downward, which in turn drives the guide wheel 806 to move downward. This allows the guide wheel 806 to adjust the tension of the PVC film, preventing wrinkles from forming during winding due to insufficient tension during surface treatment, thus avoiding damage to the PVC film.

[0028] Collection boxes 3 are connected to both sides of the housing 1. A connecting pipe 4 is connected to one side of the collection box 3, and the other end of the connecting pipe 4 extends into the housing 1 and is connected to a suction box 5. An anti-suction plate 6 is installed inside the suction box 5. An external pipe is connected to the side of the collection box 3 away from the connecting pipe 4. An installation and removal device 7 is installed inside the collection box 3. The installation and removal device 7 includes two fixing plates 701, a through groove 706, and a filter plate 702. One side of the fixing plate 701 is connected to the inner wall of the collection box 3, and the through groove 706 is opened on the outer wall of the collection box 3. A sliding groove 705 is opened on the opposite side of the two fixing plates 701. A slider 703 is connected to both sides of the filter plate 702. The outer wall of the slider 703 is slidably connected to the inner wall of the corresponding sliding groove 705. The outer wall of the filter plate 702 is attached to and slidably connected to the inner wall of the through groove 706. A pull block 704 is connected to one side of the filter plate 702. An internal groove 711 is provided at the bottom of the inner wall of the through groove 706. A fixing pin 707 is slidably connected in the internal groove 711. A fixing groove is provided at the bottom of the fixing pin 707, and a fixing rod 709 is slidably connected in the fixing groove. The other end of the fixing rod 709 is connected to the bottom of the internal groove 711. A first spring 710 is sleeved on the outer wall of the fixing rod 709. The two ends of the first spring 710 are respectively connected to the bottom of the fixing pin 707 and the bottom of the internal groove 711. A limiting groove 712 is provided in the inner wall of the internal groove 711. A limiting block 708 is slidably connected in the limiting groove 712. One side of the limiting block 708 is connected to the outer wall of the fixing pin 707. A pin hole is provided at the bottom of the filter plate 702, and one end of the fixing pin 707 is inserted into the pin hole. The top of the fixing pin 707 is arc-shaped.

[0029] In a specific implementation, by providing the installation and removal device 7, during installation, the filter plate 702 is inserted into the through groove 706, causing the slider 703 to slide into the slide groove 705. The slide groove 705 supports the slider 703, providing good support for the filter plate 702 and preventing the other end of the filter plate 702 from sagging due to lack of support, thus affecting its use. When the filter plate 702 is inserted, it presses against the fixing pin 707, causing the fixing pin 707 to move downward and compress the first spring 710. The fixing rod 709 supports the first spring 710, preventing the first spring 710 from being compressed. When the filter plate 702 is inserted into place, the first spring 710 causes the fixing pin 707 to be inserted into the pin hole, thus limiting the filter plate 702. When the filter plate 702 needs to be replaced after long-term use, the pull block 704 is pulled to one side, causing the pull block 704 to move the filter plate 702 to one side and press the fixing pin 707 through the pin hole. The fixing pin 707 moves downward through the top arc and slides out of the pin hole, thus removing the filter plate 702 for replacement. This improves the convenience of maintenance during use.

[0030] Working principle: In use, the PVC film is inserted through the inlet / outlet slot 2 on one side, then passes through the bottom of the guide wheel 806. The elastic force of the second spring 804 drives the moving block 805 to move downward, which in turn drives the connecting frame 807 to move downward. This causes the connecting frame 807 to drive the guide wheel 806 to move downward, thus tightening the PVC film and preventing wrinkles from forming during winding due to insufficient tension. Then, one end of the PVC film is passed between the two suction boxes 5 and out through the other inlet / outlet slot 2. It is then connected to the suction module through the external pipe at the top of the collection box 3, allowing the suction box 5 to remove dust from the surface of the PVC film, preventing dust from affecting subsequent use. The dust is also filtered by the filter plate 702 and collected in the collection box 3. After prolonged use, the filter plate 702 is moved by the pull block 704, causing it to slide out of the through slot 706, allowing for replacement or cleaning of the filter plate 702 and improving the convenience of device maintenance.
