Description

TECHNICAL FIELD

[0001] The utility model belongs to coextrusion film cutting field, especially relates to a coextrusion film cutting device. BACKGROUND

[0002] In the processing of the film, a raw material is extruded onto another film that has been made or different kinds of films that have been made are bonded together to become a multi-layer film, and this product is called a composite film, and compared with the composite film, the coextrusion film has most of the characteristics of the composite film, but all the layers of the coextrusion film are extruded together at the same time, so there is no aluminum foil, paper and other non-plastic materials, and the combination form of the product material is relatively less, and the application range is also smaller, but since the layers are combined by heat melting and do not need adhesive, the health safety of the food packaging coextrusion film is relatively reliable, so the coextrusion film is commonly used in pure milk bags, express bags and metal protective films.

[0003] A coextrusion film production cutting device is disclosed in Chinese Patent No. CN218110895U, which comprises a frame, the upper and lower ends of the frame are respectively provided with electric push rods, the output ends of the electric push rods extend into the interior of the frame, the output ends of the electric push rods are provided with moving blocks, and the side walls of the moving blocks are provided with sliding assemblies. The utility model adopts the above structure, and in the production process of the coextrusion film, the coextrusion film penetrates the frame, and when the coextrusion film needs to be cut off, the moving blocks are moved by the electric push rods, and the positions of the moving blocks are stabilized by the sliding assemblies, so that the moving blocks can drive the two cutters to move towards each other, so that the cutters can cut off the coextrusion film. The design of the bevel of the cutter can make the cutter have the effect of scissors, and the coextrusion film can be cut off from left to right step by step. Not only is the cutting effect good, but also the cutting is more complete, and the quality of the coextrusion film can be affected by tearing, so as to avoid the waste of part of the coextrusion film.

[0004] Through the above structure, the positions of the moving blocks are stabilized by the sliding assemblies when in use, so that the moving blocks can drive the two cutters to move towards each other, so that the cutters can cut off the coextrusion film.
