A wrinkle-removing device for plastic film

Abstract

The invention belongs to the technical field of film processing, and in particular relates to a wrinkle-removing device for plastic film, which includes a first mechanism, a second mechanism and a third mechanism which are sequentially fixed on a first fixed base along the movement direction of the plastic film; The high-frequency reciprocating extrusion and separation of the fourth roller and the fifth roller in the invention makes the wrinkles on the part of the plastic film between the fifth roller and the second roller effectively removed, while the fourth roller and the fifth roller After the roller is squeezed, the plastic film is separated instantly to relax the further tightened plastic film, avoiding the irreversible deformation of the plastic film caused by the long-term tension of the plastic film, and ensuring that the plastic film coming out of the wrinkle removal device is a qualified product. Minimize the defect rate of plastic film products, reduce the production cost of plastic film, and improve production efficiency.

Description

technical field [0001] The invention belongs to the technical field of film processing, in particular to a wrinkle-removing device for plastic films. Background technique [0002] At present, the traditional plastic film is a common daily necessities for people. The plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price. It is widely used in all walks of life; the production of plastic film must be After the production steps of forming and roll; due to the small thickness of the plastic film, the plastic film coming out of the forming device will appear wrinkled and sticky during the movement to the roll; the unwrinkled plastic film is wound on the roll Finally, the wrinkles will be permanently deformed due to long-term extrusion, and the creases caused by wrinkles on the plastic film will affect its use effect during later use. [0003] The present invention designs a wrinkle removing device ...
