[0001] The utility model relates to the technical field of edge trimming, in particular to an edge trimming device for rolled aluminum foil of non-ferrous metals. Background Art

[0002] In the non-ferrous metal processing industry, aluminum foil is a product with very high requirements. Aluminum foil is a hot stamping sheet material made by rolling metal aluminum. Aluminum foil has a soft texture, good ductility, high moisture resistance, corrosion resistance and fragrance retention, and low oxygen permeability. It is widely used as a packaging material for food, cigarettes, medicines, photographic bases and household items.

[0003] During the aluminum foil cutting and winding process, rollers are typically used to flatten the foil to ensure a smooth edge. However, this method has certain drawbacks in practice. For example, small scraps from the foil cutting may adhere to the outer surface of the rollers. As the rollers continue to roll the foil, these scraps act as foreign matter, causing indentations, scratches, and even scuffs on the foil surface, seriously affecting the foil's appearance quality and surface smoothness. Therefore, a device for trimming non-ferrous metal rolled aluminum foil is proposed to address these issues. Utility Model Content

[0025] The elastic component includes a slide rod 18 slidably connected to the outer wall of the screw sleeve 17, the end of the slide rod 18 is fixedly connected to the cleaning plate 19, the end of the slide rod 18 is fixedly connected to the limit block 20, the outer wall of the slide rod 18 is provided with a spring 21, and the two ends of the spring 21 are respectively fixedly connected to the limit block 20 and the screw sleeve 17; the elastic component ensures good contact between the cleaning plate 19 and the pressure roller 9, continuously removes waste on the pressure roller 9, ensures that the surface of the pressure roller 9 is always smooth during the processing, and avoids damage to the aluminum foil surface due to the adhesion of waste.

[0026] The inner wall of the processing frame 1 is rotatably connected to a double-headed threaded rod 11, and two groups of sliders 13 are threadedly connected to the threaded section of the double-headed threaded rod 11. The two groups of sliders 13 are fixedly connected to the two groups of cutters 14 respectively. The inner wall of the processing frame 1 is fixedly connected to a single group of limit rod 12 and two groups of limit rod 2 16. The two groups of sliders 13 are slidably connected to the outer wall of the limit rod 12, and the two groups of lead screw sleeves 17 are slidably connected to the outer wall of the adjacent limit rod 2 16 respectively. The inner walls on both sides of the processing frame 1 are rotatably connected to the waste rollers 10; the position of the cutter 14 is controlled by the double-headed threaded rod 11, so that accurate and stable trimming operation can be achieved, the problem of uneven cutting can be avoided, and the quality and accuracy of trimming can be further improved.

[0028] In the present invention, the device is specifically used as follows: at the beginning of the operation, the unloading roller 2 is loaded with the aluminum foil roll to be processed, and the unloading roller 2 smoothly feeds the aluminum foil into the processing area by rotating. When the aluminum foil passes through the inside of the processing frame 1, the aluminum foil is first fixed by the pressing roller 8 to ensure that it remains flat during the cutting process. The pressing roller 9 further guides and flattens the aluminum foil to prevent the material from offsetting or warping during the movement.

[0030] The edge waste generated during the aluminum foil cutting process is automatically collected by the waste roller 10 on the inner wall of the processing frame 1. In order to prevent the small aluminum foil waste from adhering to the pressure roller 9 during the cutting process, with the help of multiple sets of sprockets 6 and chains 7, when the pressure roller 9 rotates, the two sets of reciprocating screws 15 are synchronously driven to rotate, driving the cleaning plate 19 to slide on the outer wall of the pressure roller 9 to clean the impurities on its outer wall. The spring 21 ensures that the cleaning plate 19 is tightly attached to the outer wall of the pressure roller 9 to avoid indentations and scratches on the aluminum foil caused by the attached waste on the surface of the pressure roller 9.
