PET release film multi-stage treatment and recovery system and method

Abstract

The PET release film multi-stage processing and recycling system includes a mechanical dust removal mechanism, a cleaning mechanism, a drying mechanism and a winding mechanism. The release film passes through the mechanical dust removal mechanism, cleaning mechanism, drying mechanism in turn and is wound on the winding mechanism. The travel of the release film in the mechanical dust removal mechanism, cleaning mechanism, drying mechanism and winding mechanism and the transition between mechanisms are all guided by the guide rollers that roll and cooperate with the release film, and the mechanical dust removal mechanism, cleaning mechanism, drying mechanism The actions of the mechanism and the winding mechanism are coordinated and controlled by the electronic control system. The present invention removes dust, cleans, dries and rewinds the release film in sequence, and realizes effective removal of impurities on the surface of the used release film and recovery in rolls, so as to achieve the purpose of recycling and reuse of the release film and improve the release rate. The utilization rate of the film can reduce the production cost. The invention also provides a multi-stage treatment and recovery method for the PET release film.

Description

technical field [0001] The invention relates to a PET release film multi-stage treatment recovery system and method, belonging to the field of PET release film recovery and reuse. Background technique [0002] The substrate of PET release film is made of PET film coated with silicone oil on the surface, so it is also called silicone oil film and release film. By applying silicone oil, the adsorption force on the surface of the PET film can be reduced to achieve a release effect. Widely used in packaging and printing, flexible circuits, insulation products, circuit boards, reflective materials, waterproof materials, adhesive products and other industries. [0003] PET release film is mostly used in whole rolls. After use, there will be certain impurities such as dust, colloid, and resin residue on the surface, which will affect the effect of continued use. Most production lines adopt a one-time use mode. Therefore, the consumption of PET release film on the production line ...

AI Technical Summary

Problems solved by technology

[0011] The release film recovery equipment in the prior art cannot recover the release film with a length of more than 100 meters. Impurities on the surface of PET release film are cleanly recovered and reused
