Description

Rim charge cutting recovery unit is used in film production Technical Field The utility model relates to the technical field of film production, in particular to a rim charge cutting and recycling device for film production. Background The rim charge cutting and recycling device plays a vital role in plastic film production. The following is the main role of the device in plastic film production 1) in the plastic film production process, a large amount of rim charge and waste materials can be generated. If not handled in time, the rim charge can be accumulated on the production site, occupy space and affect production efficiency. The rim charge cutting and recycling device can cut rim charge into small blocks and collect the small blocks rapidly through automatic cutting and recycling processes, so that the tedious and time-consuming manual processing is avoided, and the production efficiency is greatly improved. 2) The main raw materials for producing the plastic film are high polymer materials such as polyethylene resin and the like, and the materials have higher cost.
