Quality inspection device in polyester film production

Abstract

The invention relates to the technical field of polyester film production and discloses a quality inspection device in polyester film production. The quality inspection device comprises a table top. Agroove and two symmetrically distributed thin grooves are formed in the top surface of the table top. The two thin grooves are located in the left side of the groove and one ends of the thin groovesextend into the groove. Two symmetrically distributed supports are fixedly arranged on the left side of the table top. A thin film roll is arranged between the two supports. A first strut, a second strut and a third strut are fixedly arranged at the top of the table top. The first strut is located on the left side of the second strut. According to the quality inspection device in polyester film production, a first motor operates to finally drive two cutting knives to move to cut a film into three sections of thin films with the same size, the trouble of manually cutting the film is omitted, the two ends of each cut film can be compressed through first electric push rods and second electric push rods, manual fastening is avoided, the time and manpower are saved, meanwhile, three samples arestretched and detected, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of polyester film production, in particular to a quality inspection device in polyester film production. Background technique [0002] Polyester film (PET) is a film material 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 are widely used in glass fiber reinforced plastic industry, building materials industry, printing industry, medicine and health. Polyester film is also called polyester film, polyester film, photosensitive paper, polyester film, benzene tin film, cellophane release film. With the development of the economy and the adjustment of the agricultural industry structure, the competition in the plastic film manufacturing industry is intensifying. Domestic excellent plastics Film production enterpris...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a quality inspection device in the production of polyester film, which has the advantages of simple operation, high degree of automation, and high detection efficiency, and solves the problem that the existing stretch detection of the film usually uses cutting For a small piece of film, manually clamp the two ends of the film and then stretch it through the machine. This method is inefficient, and it is time-consuming and labor-intensive to repeat the operation when testing multiple samples.
