[0002] Automobile film, also known as solar insulation film, is generally a film composited with a PET substrate. It has a water-soluble pressure-sensitive adhesive that can stick tightly to glass fragments. When a car accident occurs or the windshield is hit by criminals, the glass fragments will not fall off and fly. It can also effectively block the infrared light area. During the production process of automobile film, the electroplating direction is fixed, resulting in a consistent shrinkage direction. In order to reduce bubbles and creases, it needs to be rolled according to the shape of the glass, which can also better save material costs.

[0003] However, in the prior art, in order to avoid the loss of lateral pulling force between the membrane cloths after cutting and separation, which causes the membrane cloths to move to both sides and affect the flatness of the winding, the winding rollers need to be close to each other. If they are too close, it is easy for the membrane cloths to slightly deviate during movement and collide with each other, affecting the position of adjacent membrane cloths and easily causing wrinkles during winding.

The top surfaces of the frames 1 are all provided with tension rollers 4, the unwinding frame 2 and the top inner layers of each winding frame 5 are rotatably connected with connectors 7 through bearings, the outsides of the unwinding frame 2 and one of the winding frames 5 are provided with servo motors 6, and one end of each connector 7 extending to the outside of the winding frame 5 is fixed with a pulley 8, and every two adjacent pulleys 8 are connected by a transmission belt 9, and the outsides of the unwinding frame 2 and one of the pulleys 8 are provided with servo motors 6, and the output ends of the servo motors 6 are respectively fixed on the connector 7 and the pulleys 8.

[0024] The following is a detailed description of the specific settings and functions of this embodiment: an adjustment groove is provided at the top of the cutting bracket 3, and a number of connecting screws 17 are equidistantly slidably sleeved in the adjusting groove. Each connecting screw 17 is set to a T-shaped rectangular column with each adjusting groove. The top of each limiting slider 16 extends to the inside of the adjusting groove. The width of each fixing nut 18 is greater than the width of the adjusting groove. A limiting slider 16 is fixed to the bottom of each connecting screw 17, and a knife sleeve 15 is fixed to the bottom of the limiting slider 16. The cutting blade 19 is clamped and fixed inside the knife sleeve 15. The limiting slider 16 on the top and bottom surfaces of the cutting bracket 3 is threaded with a fixing nut 18. A pad roller is rotatably connected to the inside of the cutting bracket 3 below the cutting blade 19. By adjusting the spacing between adjacent cutting blades 19, the width of the automotive film during reeling is adjusted, thereby improving the applicability of the reeling machine.

[0025] Example 2

[0026] like Figure 1-4 As shown, smoothing rollers 11 are provided inside the unwinding frame 2 and the winding frame 5 below the connecting head 7, and both ends of each smoothing roller 11 are rotatably connected to a connecting plate 10 through a bearing, and the outer side of each connecting plate 10 is slidingly connected to the inside of the unwinding frame 2 and the winding frame 5 respectively, and a sliding sleeve 12 is fixed to the outer side of each connecting plate 10, and the sliding sleeve 12 is slidingly connected to the inside of the unwinding frame 2 and the winding frame 5 respectively, and a sliding rod 14 is slidingly sleeved inside each sliding sleeve 12 and the spring 13, and the upper and lower ends of the sliding rod 14 are fixed inside the unwinding frame 2 or the winding frame 5, and a spring 13 is fixed between the bottom of each sliding sleeve 12 and the inside of the unwinding frame 2 or the winding frame 5.

[0027] The effect achieved by the entire embodiment is that, through the design of the smoothing roller 11 abutting against the unwinding roller and the winding roller, the automobile film can be smoothed promptly and effectively, and the automobile film can be pushed so that it is tighter when wound, thereby facilitating subsequent storage or use.

[0028] The method of use and working principle of this device: when in use, first adjust the distance between the cutting blades 19 according to the slitting width. When adjusting, screw the fixing nut 18 to release the clamping fixation of the fixing nut 18 on the cutting bracket 3, then pull the connecting screw 17 to adjust the distance between adjacent cutting blades 19. After the adjustment is completed, screw the fixing nut 18 to clamp and fix the cutting bracket 3. Then, assemble the support roller in the roll of automobile film raw material on the unwinding frame 2, and push the smoothing roller 11 so that the smoothing roller 11 drives the connecting plates 10 on both sides to move downward. When the connecting plate 10 moves downward, it drives the sliding sleeve 12 to slide down on the sliding rod 14 to compress the spring 13. Insert one end of the support roller into the connector 7 and engage the other end into the unwinding frame 2. Loosen the smoothing roller 11 so that Pushed by the spring 13, the smoothing roller 11 abuts against the outermost layer of the raw material roll, pulling the automobile film so that the automobile film passes through the tension roller 4 in turn, and then passes between the bottom of the cutting blade 19 and the pad roller in the cutting bracket 3, and then continues to pull the automobile film. When pulling, the cutting blade 19 cuts the automobile film. After cutting, the winding rollers are assembled on the winding rack 5 and fixed on the winding rollers at the corresponding positions. After cutting, the adjacent automobile film sheets are pulled to different winding racks 5. The servo motor 6 on the winding rack 5 runs and drives all the winding rollers to rotate through the pulley 8 and the transmission belt 9, thereby driving the winding rollers to rotate for winding. When winding, the smoothing roller 11 in the winding rack 5 always abuts against the outermost layer of the roll body after the automobile film is rolled, smoothing and pressing the automobile film to complete the rolling.
