Embodiment Construction

[0040] Combine below Figure 1 to Figure 6 Embodiments of the present invention are described in detail.

[0041] The PET release film multi-stage treatment recovery system is characterized in that it includes a mechanical dust removal mechanism 1 for dedusting the used release film, a cleaning mechanism 2 for cleaning the dedusted release film, and a cleaning mechanism for cleaning the dedusted release film. The drying mechanism 3 for drying the cleaned release film and the winding mechanism 4 for rewinding the dried release film. The release film passes through the mechanical dust removal mechanism 1, the cleaning mechanism 2, and the drying mechanism in turn. Mechanism 3 is rewound on the rewinding mechanism 4, and the travel of the release film in the mechanical dust removal mechanism 1, the cleaning mechanism 2, the drying mechanism 3 and the rewinding mechanism 4 and the transition between the mechanisms are all passed by rolling with the release film The matching guide...

Abstract

A multi-stage treatment and recovery system for PET release films comprises a mechanical dust removal mechanism, a cleaning mechanism, a drying mechanism and a winding mechanism, wherein the release film sequentially passes through the mechanical dust removal mechanism, the cleaning mechanism and the drying mechanism and is wound on the winding mechanism; traveling of the release films in the mechanical dust removal mechanism, the cleaning mechanism, the drying mechanism and the winding mechanism and transition among the mechanisms are guided by a guide roller in rolling fit with the release films; and the actions of the mechanical dedusting mechanism, the cleaning mechanism, the drying mechanism and the winding mechanism are uniformly and coordinately controlled by an electric control system. According to the multi-stage treatment and recovery system for the PET release films, the release films are subjected to dust removal, cleaning, drying and winding in sequence, so that surface impurities of the used release films can be effectively removed, wound and recycled, the purpose of recycling the release films is achieved, the utilization rate of the release films is improved, and the production cost is reduced. The invention also provides a multi-stage treatment and recovery method for the PET release films.

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 ...
