[0002] During the production process of aluminum coils, cleaning is required to remove oil stains, impurities and oxides on the surface of the aluminum coils. Cleaning the aluminum coils is crucial for subsequent coating treatment. The purpose of cleaning is to ensure the cleanliness of the aluminum coil surface so that the paint can adhere evenly to the aluminum coil, forming a strong and beautiful coating, ensuring the uniformity of the coating treatment and the adhesiveness of the paint, thereby improving product quality and reducing waste. After the aluminum coil cleaning is completed, oiling treatment is required. After the aluminum coil is oiled, trimming treatment is carried out. The purpose of the trimming treatment is to remove the irregular parts at the edges of the aluminum coil, make the edges of the aluminum coil neat and smooth, and cut the aluminum coil into the finished width required for production.

[0003] Currently, trimming equipment is usually used to cut both sides of the aluminum coil after the oiling treatment. However, the surface of the aluminum coil after the oiling treatment is coated with DOS oil, and knife sleeve marks will appear on the surface of the aluminum coil after shearing, which cannot meet the production requirements; moreover, it is inconvenient to press the aluminum strip, which is likely to affect the trimming effect of the aluminum coil, resulting in burrs on the edges of the aluminum coil again. At the same time, it is not suitable for the production requirements of aluminum coils of different sizes, and the production efficiency is low. Summary of the Invention
