Description

A kind of PVC film processing equipment

technical field

The invention belongs to the technical field of polyvinyl chloride processing, and in particular relates to a PVC film processing equipment.

Background technique

With the development of the times, PVC film is gradually winning people's favor with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. The darling of PVC film can be seen everywhere in people's daily life. Due to the small thickness of the PVC film, wrinkles often appear during the manufacturing process, which affects the later use effect. In order to solve the above problems, a device for leveling and feeding the PVC film has appeared in the prior art, and the material is fed by a feeding roller, and then the material is leveled by corona. However, under this structure, the feeding roller is installed by snapping into the frame, which is time-consuming and labor-intensive to disassemble and assemble; moreover, the connection of the feeding roller to the frame is not stable enough, and it is prone to shaking or disengagement.
