Description

Multilayer extrusion lamination compound unit Technical Field The application relates to the technical field of extrusion lamination composite equipment, in particular to a multilayer extrusion lamination composite unit. Background The plastic extrusion laminating machine set is one kind of equipment for coating plastic film layer on the surface of paper, BOPP, BOPET and other base material, and has polyethylene and polypropylene as main material. The equipment enhances the tensile strength, air tightness and moisture resistance of the base material through a melt extrusion process, and is widely applied to the production of packaging materials such as cement, chemical products, feeds and the like. In the actual production process, after the composite film is extruded and laminated, the edge of the composite film is often irregular, rough, and the width exceeds standard. The method is characterized in that when the laminated film is extruded, the coating amount of the edge of the base material is difficult to accurately control, and the base material is easy to slightly deviate, stretch and the like in the conveying process, so that the formed composite film is accumulated with redundant materials or has saw-tooth-shaped and wavy defects. The unqualified edges not only affect the appearance quality of the packaging material, but also cause a series of problems in the subsequent rolling, cutting, printing and other procedures, such as uneven tightness of coiled materials during rolling, easy occurrence of loose rolls and wrinkles, possibility of generating scraps in the carrying or using process of the rough edges, pollution to packaging contents, incapability of meeting the specification requirements of subsequent processing equipment by using composite films with over-standard width, and direct reduction of the product qualification rate.
