A flattening device for protective film winding

Abstract

The invention discloses a flattening device for protection film winding, and relates to the technical field of film processing. The flattening device for protection film winding comprises a workbench, wherein a fan is installed on the upper surface of the workbench; an air outlet of the fan is connected with a main pipe; two vertically-arranged vertical plates are welded on the upper surface of the workbench; first support rods and a second support rod are installed between the two vertical plates; not less than three first support rods are provided; the not less than three first support rods are equidistantly distributed from the left to right; and a press roll is installed on each first support rod. According to the flattening device for protection film winding, which is disclosed by the invention, gas flow ejected by a spray head enables suspension parts at the two sides of a protection film to shake, thus preventing the edge of the protection film from adhesion and wrinkles; and moreover, the length of a support roll at the bottom of the protection film is gradually increased and the suspension parts at the two sides of the protection film are gradually reduced with the movement of the protection film from the left to right, thus a flattening purpose is achieved, the quality of the protection film is improved, and the winding is facilitated.

Description

technical field [0001] The invention relates to the technical field of film processing, in particular to a flattening device for winding a protective film. Background technique [0002] Plastic film is a common daily necessities for people. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price, and is widely used in various industries. At present, the production of domestic plastic film is to add various raw materials such as resin, plasticizer, stabilizer and filler according to the formula into a high-speed mixer for full mixing, and the mixed material is sent to the screw extrusion The machine is pre-plasticized, and then the material is transported to the rolling mill for repeated plastication. At the same time, the plasticized gas can also be discharged, and then the material is sent to the filter through the conveyor belt for filtration, and then the material is sent to the filter by the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a flattening device for winding the protective film, which solves the problem that the protective film needs to be wound after the processing and production is completed. During the winding process of the protective film, the edge of the protective film is easy to Wrinkles and adhesions will eventually lead to insufficient winding of the protective film, which will affect the quality of the protective film
