Abstract

The utility model provides an edge pressing device for producing a metallized polypropylene film, which belongs to the technical field of polypropylene film production and aims to solve the problem that in the existing hot pressing shaping process of the edge of the metallized polypropylene film, the hot pressing plate and the edge of the film are always adhered, so that the problem that the production efficiency is affected due to the fact that the frequency of manual intervention is increased. In the edge pressing operation, the hot pressing plate automatically drives the arc-shaped pressing block to press downwards when rising, so that films which are possibly adhered can be automatically separated, and meanwhile, the automatic telescopic limiting plate prevents the film from being placed too far back, so that the production efficiency is improved, and the product quality is ensured.
