[0002] Aluminum foil is a key material in the fields of aluminum electrolytic capacitors, packaging materials (such as food packaging, cigarette packaging, and medical packaging), and its slitting processing is an important link in the production process.

[0003] When traditional aluminum foil slitting equipment cuts aluminum foil, due to various reasons, fine metal chips or dust will fall off the surface of the aluminum foil. These powders will adhere to the cut surface of the aluminum foil, so that obvious metal powders can often be seen on the edge or cut surface of the aluminum foil after slitting. At the same time, these powders will also adhere to the cutter and guide roller, especially the cutting groove on the guide roller is prone to accumulate aluminum powder, affecting the cutting quality. The powder loss will make the surface of the aluminum foil after slitting not clean enough, which is particularly problematic for applications requiring high cleanliness (such as food packaging, medical packaging, etc.) and continuous powder loss will accumulate in the production environment, which not only affects the health of workers, but may also damage production equipment, resulting in a deterioration of the working environment and reduced product cleanliness. In addition, during long-term use, the cutter will become blunt, which will produce more aluminum powder on the cutting surface when slitting aluminum foil, which is very inconvenient to use.

[0004] Therefore, a slitting device for aluminum foil is invented, which can clean the slitting device and collect aluminum powder when the aluminum foil is cut, so as to solve the problems arising from the above-mentioned background technology. Utility Model Content

The slitting roller 5 is rotatably connected to the mounting seat 1 and is located at the upper end of the guide roller 7. A cutter 9 for slitting the aluminum foil roll is provided on the slitting roller 5. The cutter 9 corresponds to the guide groove 8 one by one. When the aluminum foil passes through the guide groove 8, it is cut by the cutter 9. A winding roller 10 for winding the slit aluminum foil roll is rotatably connected to the mounting seat 1. In this embodiment, the transmission chamber is fixedly provided with driving motors for driving the slitting roller 5, the guide roller 7, the aluminum roll roller 6, and the winding roller 10 to rotate respectively;

[0028] The roller surface cleaning mechanism 11 is used to clean the surface of the guide roller 7. The roller surface cleaning mechanism 11 is arranged at the lower side of the guide roller 7 and includes a collecting groove 12. The two ends of the collecting groove 12 are fixed on the mounting seat 1. A cleaning brush 13 that can clean the guide groove 8 is rotatably connected in the collecting groove 12. A plurality of jet heads 14 that can blow the surface of the guide roller 7 are fixedly connected in the collecting groove 12. The jet heads 14 are installed on the front and rear inner walls of the collecting groove 12 to blow the guide roller 7 passing through the collecting groove 12. The jet direction of the jet head 14 is tangential to the peripheral side of the guide roller 7. A driving mechanism that drives the cleaning brush 13 to rotate is arranged in the transmission cavity. Specifically, the guide roller 7 in the transmission cavity is driven by the cleaning brush 13. A driving pulley is fixedly connected to the guide roller 7, one end of a cleaning brush 13 extends into the transmission cavity and is provided with a driven pulley connected to the driving pulley. When the guide roller 7 drives the driving pulley to rotate, the driving pulley drives the driven pulley to rotate, and the driven pulley drives the cleaning brush 13 to purge the guide groove 8.

A compression spring 19 is fixedly connected to one end of the sliding plate 16 away from the scraper. The other end of the compression spring 19 is fixedly connected to the mounting seat 1. The compression spring 19 makes the sliding plate 16 always drive the scraper block 17 to keep in contact with the cutter 9. A rotatable rotating shaft 20 is rotatably connected to the mounting seat 1.
