AI Technical Summary

Technical Problem

When traditional coating machines apply antistatic liquid to one side of a film, the frequency of antistatic liquid application is uneven, resulting in uneven coating and requiring sealing components to prevent leakage, which affects the coating effect on the film surface.

Method used

A film modification device was designed, which uses a material trough and deformation component distributed in a ring on the coating roller. By rotating the coating roller in the opposite direction to the conveyor belt, uniform coating is achieved by using the deformation component and scraping component of the material trough. Combined with the material feeding pool and the material return pool, the uniform coating and effective utilization of the antistatic liquid are ensured.

Benefits of technology

This method achieves uniform coating of antistatic liquid on the film surface, avoiding uneven coating and liquid leakage, and improving coating efficiency and coating quality.

Abstract

The present application relates to the field of film production, especially to a film modification device, comprising a conveying belt, the conveying belt is provided with a motor, a coating roller is arranged above the conveying belt, the coating roller is kept reverse rotation with the conveying belt, the surface of the coating roller is annularly distributed with a plurality of axially extending troughs, the bottom of the trough is provided with a deformation assembly; a mandrel is rotatably arranged in the coating roller, the mandrel has a reduced diameter portion and an enlarged diameter portion, a feeding pool is arranged on the top of the coating roller, and a material scraping assembly is arranged above the conveying belt, a plurality of troughs are uniformly arranged on the surface of the coating roller, the troughs continuously feed downward during the rotation of the coating roller, the pressing plate follows the rotation and is positioned with the enlarged diameter portion of the mandrel, and is used for extruding the rubber strip to discharge all the antistatic liquid in the trough on the surface of the film, so that the feeding interval on the surface of the film in transmission is uniform, and the feeding amount is the same each time, and then the antistatic liquid is coated on the surface of the film through the return pool, so that the coating uneven phenomenon caused by excessive material accumulation is effectively avoided.
