System used for PVC membrane machining

Abstract

The invention discloses a system used for PVC membrane machining. The system used for PVC membrane machining comprises a heating device used for performing heating treatment on materials, a feeding device used for conveying the materials, a corona device used for performing corona treatment on the heated materials, a cooling device used for cooling the materials and a material receiving device; the feeding device is arranged between the heating device and the corona device; and auxiliary pieces comprise an inner piece, an outer piece at least partially made from a flexible material, a pushingpiece arranged in the inner piece and matched with the outer piece, and a driving piece matched with the pushing piece. According to the system used for PVC membrane machining, the outer piece can bepushed by the pushing piece to deform, the deformation degree can be adjusted when the materials are wrinkled, so that the materials can be restored to be level, and it is guaranteed that the materials are in a level state all the time in the conveying process.

Description

Technical field [0001] The invention belongs to the technical field of polyvinyl chloride processing, and in particular relates to a system for PVC film processing. Background technique [0002] With the development of the times, plastic film, especially PVC film, has gradually won people’s favor with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. In European and American countries, PVC film It is the darling of the construction industry, PVC film can be seen everywhere in people's daily life. Due to the small thickness of the PVC film, wrinkles often occur during processing and feeding. In order to solve the above situation, there is a processing device in the prior art that uses corona to flatten the surface of the plastic film, but this kind of equipment cannot guarantee that the material is in a flat state when it is sent to the corona step, and the plastic film often wrinkles When entering the c...

Problems solved by technology

In order to solve the above-mentioned situation, there have been processing equipment in the prior art that use corona to smooth the surface of the plastic film, but this kind of equipment cannot ensure that the material is in a flat state when it is fed into the corona step, and the plastic film often appears wrinkled. After entering the corona equipment, the flatness of the material after corona cannot be improved, which is time-consuming and laborious
