Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic film production technology, and in particular to a cutting device for aluminum-plastic film. Background Technology

[0002] Aluminum-plastic film is a thin film composed of multiple layers of materials. It has good barrier properties, moisture resistance, oxygen barrier properties, and weather resistance, and plays an important role in construction, packaging, medicine, electronics and other fields.

[0003] In the production process of aluminum-plastic film, the finished aluminum-plastic film is usually cut into a specified width by a slitting device. In the prior art, such as Chinese utility model patent with announcement number CN221587543U, a slitting device for PET film is disclosed. The device uses an elastic element to make the cutting blade edge fit tightly against the surface of the extrusion roller, thereby increasing the shearing force of the cutting blade and improving the cutting effect on the film material.

[0004] However, in the aforementioned slitting device, the close contact between the cutting blade and the extrusion roller increases the pressure between them. Furthermore, the friction generated by the cutting blade during the cutting process causes heat to rise, affecting the accuracy and stability of the cut. High temperatures also lead to localized softening and deformation of the film at the cutting point, reducing the smoothness of the cut and increasing the likelihood of burrs, thus lowering the slitting quality. The increased temperature also accelerates the blade's wear process, causing oxidation reactions at the blade edge, forming an oxide layer. This oxide layer reduces the blade's hardness and sharpness, increases cutting resistance, reduces blade toughness, further decreasing slitting accuracy and shortening blade lifespan. When using the blade to slit aluminum-plastic film, tiny particles generated by cutting, tearing, or friction are produced at the cutting area. These particles adhere to the blade or the cutting area, easily affecting the cutting quality and causing environmental pollution.
