Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, and in particular to a rewinding machine capable of recovering a release film. Background Art

[0002] The rewinder is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper rolls produced by the papermaking machine in sequence. After rewinding, the paper is made into finished paper and shipped out of the factory.

[0003] PVC blue film is a tape used for gold removal in the production process of circuit integration. It has strong viscosity, so the coating production needs to use a release film as an isolation and protection during surface lamination, so that the adhesive surface will not stick to the extrusion roller during lamination, and it is not easy to produce bubbles and embossing on the adhesive surface, thereby protecting the adhesive surface for recycling into rolls. Finally, when the strips are divided into different specifications, a process is required to tear off the release film. The traditional film tearing process is numerous and greatly increases the production cost. The integrity of the release film cannot be guaranteed during the tearing process, and it cannot be recycled and reused later. The cutting and rewinding process cannot eliminate bubbles that affect the appearance;
