Abstract

The invention relates to the technical field of film preparation methods, in particular to a preparation method for an optical polyester film. According to the preparation method, preparation equipment comprises a film production device and a collecting device, the collecting device is fixedly arranged right below the film production device, a conveying frame is fixedly arranged in the film production device, a fixing rod is welded to the upper surface of the conveying frame, leftover material rolls are fixedly connected to the two side edges of the polyester film, a supporting rod is fixedly arranged in the conveying frame in an inserted mode, an alarm lamp is fixedly connected to the top end of the supporting rod, a supporting base is fixedly arranged in the collecting device, winding devices are symmetrically and movably arranged at the two ends of the interior of the supporting base, and triggering devices are symmetrically and movably arranged at the bottom edges of the two ends of the supporting base. The preparation method has the advantages that real-time winding of leftover materials of the polyester film can be realized, workers can conveniently conduct centralized cleaning on the leftover materials of polyester film, and the situation that normal operation of the production equipment is affected due to the fact that the leftover materials of the polyester film is stacked on the ground can be avoided.

Description

technical field [0001] The invention relates to the technical field of film preparation methods, in particular to a preparation method of an optical polyester film. Background technique [0002] Optical polyester film is made of polyethylene terephthalate as a raw material, which is made into a thick sheet by extrusion and then biaxially stretched. Polyester film environmental protection film PET film, milky white film and other printing and packaging Consumables, widely used in glass steel industry, building materials industry, printing industry, medicine and health, polyester film is also called polyester film light sheet, polyester film, photosensitive paper, polyester film, benzene tin film, cellophane, release film, etc. [0003] At present, in the production process of optical polyester film, in order to obtain the polyester film of the required size, the polyester film is usually cut when the polyester film is transmitted, so as to obtain a polyester film roll that me...
