Film-pressing roller assembly of thin film processing assembly line

Abstract

The invention discloses a film-pressing roller assembly of a thin film processing assembly line. The film-pressing roller assembly structurally comprises rollers, a scraper structure, a rack and a motor, the rollers are mounted on the inner side of the rack, the scraper structure is arranged below the rollers, and the signal output end of the motor is electrically connected with the connecting ends of the rollers. The film-pressing roller assembly is provided with mounting plates, sectional cavities and partition plates, cylindrical structures matched with the rollers are formed by the structures, and every three supporting devices are evenly distributed on the inner side in a circumference and used for abutting against the inner surfaces of the rollers, so that the rollers are not prone to deforming; and through matching of elastic air bags inside the supporting devices and opening cavities, telescopic rods move upwards during film pressing, connecting rods can further deform to pushjacking rods to deform, and the elastic air bags deform to jack the mounting plates so as to prevent the phenomenon that the rollers deform under high pressure, and consequently, the apparent qualityof a product is affected or the thickness is uneven.

Description

technical field [0001] The invention relates to the field of film processing, in particular to a laminating roller assembly of a film processing line. Background technique [0002] The film is a thin and soft transparent sheet, which is made of plastic, adhesive, rubber and other materials. The film is usually divided into polyethylene film, polypropylene film and polyvinyl chloride film. During the processing of the film, the material is first melted, then formed, cooled, and finally rolled up by the receiving mechanism. After the film is formed and cooled, in order to prevent the film from wrinkling during the transmission process, usually Several groups of rollers arranged side by side are required to perform lamination. [0003] The internal support of the mounting plate of the laminating roller assembly in the existing film processing line is insufficient. When laminating the film, the roller will be deformed under high pressure, which will affect the apparent quality ...

AI Technical Summary

Problems solved by technology

[0004] For the above-mentioned existing film processing line, the internal support of the mounting plate of the lamination roller assembly is not strong enough. When laminating the film, the roller will deform under high pressure, which will affect the apparent quality of the product or the thickness will be uneven, resulting in production failure. Efficiency and pass rate are reduced, and due to environmental reasons, if the roller is sticky and fine debris enters during compression molding, it is easy to cause indentation on the film surface during hot pressing, affecting the quality of the film, and it is difficult to meet high-precision production requirements Problem, the present invention provides a laminating roller assembly of a film processing line
