Thin film casting equipment for preparing new polymer packaging material thin film

Abstract

The invention discloses thin film casting equipment for preparing a new polymer packaging material thin film in the technical field of film thin processing. The thin film casting equipment comprises a bottom plate, the front side and the rear side of the left end of the top of the bottom plate are fixedly connected with two symmetrically-arranged first mounting plates, the inner walls of the two first mounting plates are jointly and fixedly connected with a casting box, second mounting plates are symmetrically and fixedly connected to the front side and the rear side of the top of the bottom plate, first arc-shaped sliding grooves and second arc-shaped sliding grooves are formed in the left sides and the right sides of the inner walls of the two second mounting plates correspondingly, and the two first arc-shaped sliding grooves are slidably connected with first rotating shafts correspondingly. According to the thin film casting equipment, when a casting machine breaks down, protection can be carried out on the thin film, damage to the thin film can be greatly reduced, and the production quality of the thin film can be improved.

Description

technical field [0001] The invention relates to the technical field of film processing, in particular to a film casting device for preparing films of new polymer packaging materials. Background technique [0002] With the increasing development of the packaging industry, the use of film is increasing, and the quality requirements of the film are getting higher and higher. Due to the fast production speed of the cast film machine, the film produced has good transparency, uniform thickness, and stab resistance. With the advantages of good wearability and stretchability, it has become the main production equipment of film. [0003] When the film casting machine in the prior art is producing the film, the film needs to be wound up after the film is dried. The winding of the film is in the best state when it is slightly stretched. However, if the casting machine breaks down during the winding process, the export speed of the film will change. If the winding device maintains the ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of film cast equipment that prepares new polymer packaging material film, to solve the prior art film cast machine that proposes in above-mentioned background technology when carrying out film production, need film after film drying During the winding process, the export speed of the film needs to be the same as the winding speed. At this time, the film can always be kept in a slightly taut state for winding, and the film winding is in the best state, but in If the casting machine breaks down during the winding process, the export speed of the film will change. At this time, if the winding device keeps the original speed for winding, the film will be loose or too tight, and the loose state will be The film will be stacked when it is rolled, and the film will be plastically deformed if it is too tight. Both states will affect the quality of the film and need to be processed, which will seriously affect the production speed of the film.
