[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-2This utility model provides an embodiment: an automatic sunscreen film cutting machine, including a support base 1, a movable rod 2, a guide roller 3, a cutting blade 4, an ultraviolet sensor 5, and a winding rod 6. The movable rod 2, which is bent, is installed on the left side of the front support rod of the support base 1. The guide roller 3, which transports the sunscreen film, is installed vertically and parallel to the right side of the support rod between the support bases 1. A cutting blade 4 for cutting the sunscreen film is located behind the guide roller 3. An ultraviolet sensor 5, triggered by ultraviolet light, is installed behind the cutting blade 4. A winding rod 6 for winding the cut sunscreen film is located behind the ultraviolet sensor 5. By adding the movable rod 2, guide roller 3, cutting blade 4, ultraviolet sensor 5, and winding rod 6, the movable rod 2 can quickly change its position to ensure that the film is always in the correct position during transport, providing a precise guiding path for the sunscreen film, achieving high-precision cutting, real-time monitoring of the sunscreen film's ultraviolet blocking effect, intelligent control to improve automation, and the ability to automatically adjust the film according to different production speeds and film material characteristics. The speed and tension of the winding are dynamically adjusted to ensure that the film material is tightly and evenly wound onto the winding rod 6. A groove is opened at the top of the support rod at the front end of the support base 1, and a support frame 14 is installed inside the groove. An installation groove 7 is opened on the right side of the groove, and a horseshoe-shaped buffer pad 8 is installed in the installation groove 7. A roller 10 is installed above the support frame 14, and a bearing 9 is mounted on the left side of the roller 10. A movable rod 2 is mounted on the outside of the bearing 9, allowing the equipment to flexibly adjust the height and angle of the support structure according to different production needs. The horseshoe-shaped buffer pad 8 in the installation groove 7 can effectively absorb the production generated during equipment operation. To minimize vibration and impact, and facilitate the installation of the sunscreen film, a circular groove 16 is cut into the surface of the support rod in the middle of the support base 1. A bushing 13 is installed inside the circular groove 16, and a roller 10 is installed inside the bushing 13. A guide roller 3 is fitted outside the roller 10. A reinforcing rod 12 is installed below the guide roller 3 to reinforce the support base 1, providing a precise guiding path so that the guide roller 3 can rotate flexibly as needed. When the equipment is running at high speed or processing large areas and thick sunscreen films, it may shake, affecting production accuracy and equipment life. The reinforcing rod 12 can effectively reduce this shaking.

[0022] Please see Figures 3-4In this embodiment, a bushing 13 is installed in the circular groove 16 inside the P-shaped support column 15. A long groove 17 is opened behind the circular groove 16 of the P-shaped support column 15. A protective cover 21 is installed at the upper end of the long groove 17. A hydraulic column 20 is installed inside the protective cover 21. A connecting block 19 is installed at the output end of the hydraulic column 20. One end of the connector 18 is installed inside the connecting block 19, and the other end of the connector 18 is installed inside the cutting blade 4, providing a stable support structure for the relevant components. The height of the cutting blade 4 can be automatically adjusted, enabling precise control of its position and improving cutting accuracy. A telescopic base plate 23 is installed below the cutting blade 4, with an inclined platform at the front end of the telescopic base plate that matches the cutting edge of the cutting blade 4. Telescopic baffles 22, which extend and retract with the telescopic base plate 23, are installed on both sides of the telescopic base plate 23. A telescopic baffle 22 is also installed on the right side of the P-shaped support column 15. When cutting sunscreen films of different thicknesses, the distance between the telescopic base plate 23 and the cutting blade 4 can be adjusted, allowing the cutting blade 4 to better adapt to cutting film materials of different thicknesses. Whether processing large-area sunscreen films or small-sized film materials, the telescopic baffles 22 can be adjusted according to the actual situation, enabling the equipment to adapt to different production tasks and improve equipment performance. For flexibility, the ultraviolet sensor 5 is fitted with a middle carrier cover 28. An ultraviolet lamp 30 is installed inside the upper part of the middle carrier cover 28. A connecting plate 27 is installed below the middle carrier plate. Support columns 24 are installed on both sides of the connecting plate 27. This allows for real-time monitoring of the sunscreen film's blocking effect on ultraviolet rays. The combination of the middle carrier cover 28 and the ultraviolet lamp 30 provides a stable and controllable ultraviolet environment for testing. This real-time intelligent control improves the automation level of the equipment. D-shaped connecting plates 25 are installed on the front and rear sides of the support columns 24. The D-shaped connecting plates 25 have circular grooves 16 inside. D-shaped connecting plates 25 are installed at both ends of the tightening roller 26. Support columns 29 are installed on both sides of the winding rod 6, allowing the tightening roller 26 to rotate flexibly on a specific track and be adjusted according to different film material characteristics.

[0023] During operation, the operator first moves the roller 10 using the movable lever 2, then inserts the sunscreen film into the roller 10. An impact force is generated, which is cushioned by the horseshoe-shaped buffer pad 8. The sunscreen film is then passed through the guide roller 3. Once preparation is complete, the support base 1 is moved to the appropriate position using the roller 11. The sunscreen film is then transferred to the second set of guide rollers 3, passed through the tightening rod, and the button on the P-shaped support column 15 is pressed to rotate the guide rollers 3 and transport the sunscreen film. Then, pull the telescopic base plate 23 according to the needs, so that the telescopic baffle 22 is adjusted together, and the ultraviolet sensor 5 and ultraviolet lamp 30 are activated. When the sun protection film passes through the middle plate and covers the ultraviolet sensor 5, the ultraviolet lamp 30 cannot trigger the ultraviolet sensor 5, so that the hydraulic rod moves up and down. The connecting block 19 drives the connecting piece 18 and the cutting blade 4, so that the cutting blade 4 cuts the sun protection film. The cut sun protection film is automatically wound up by the winding roller through the second set of tightening rods in the rear D-shaped connecting rod.

[0024] Through the above steps, by adding movable rod 2, guide roller 3, cutting blade 4, ultraviolet sensor 5, and winding rod 6, the roller 10 is moved by movable rod 2, and then the sun protection film is threaded into the roller 10. For sun protection films of different widths required for different car window models or different application scenarios, movable rod 2 can quickly change its position to ensure that the film is always in the right position during the transmission process, providing a precise guiding path for the sun protection film. The ultraviolet sensor 5 and ultraviolet lamp 30 are activated. When the sun protection film passes through the middle plate and covers the ultraviolet sensor 5, the ultraviolet light is activated. The linear light 30 cannot trigger the ultraviolet sensor 5, causing the hydraulic rod to move up and down. The connecting block 19 drives the connecting piece 18 and the cutting blade 4, so that the cutting blade 4 cuts the sunscreen film. This enables high-precision cutting, real-time monitoring of the sunscreen film's UV blocking effect, and intelligent control to improve automation. It can automatically adjust the winding speed and tension according to different production speeds and film characteristics to ensure that the film material is tightly and evenly wound on the winding rod 6, thus solving the problems of limited automation and poor flexibility of traditional automatic sunscreen film rolling and cutting machines.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
