How to solve the problem of film wrinkling in the work of film blowing machine-production site-centralized extraction of plastic net

This problem is often encountered in the production of film blowing machine. No matter how to adjust the equipment, the cause of film wrinkling can not be solved. Through analysis, it is concluded that the correct adjustment of herringbone plate and insert plate can effectively solve this problem. When producing double-layer film with herringbone plate, the smaller the included angle of herringbone plate, the better the surface quality of film. For the production of wide four-layer film, under the joint action of herringbone plate and insert plate, the stress on the film is complex, and the performance is different for different materials and different process formulas. It can be adjusted by adjusting the included angle of herringbone plate to meet the requirements of film production. The requirement for the plug-in board is that the surface of the plug-in board should be smooth, and there should be no burrs and protrusions. If the herringbone plate is water-cooled, the insert plate should also be water-cooled, so as to facilitate the uniform cooling of the film and improve its appearance quality. The adjustment of herringbone plate and insert plate can solve the above problems when the film blower works, and ensure that the film blower produces high-quality products.
