AI Technical Summary

Technical Problem

The paper-making coating device of the existing release paper is prone to bubbles between the release agent and the release paper during use, reducing the coating effect, and it is impossible to recover excess release agent without the help of external equipment, thereby increasing processing costs.

Method used

A paper-making coating device including a coating mechanism, an agitating mechanism and a recycling mechanism is designed. The coating mechanism drives the coating brush and scraper to move through an electric telescopic rod and a driving motor to ensure that the release agent is evenly coated and avoid bubble generation. The agitating mechanism effectively agitates the stored release agent by agitating the blade and gear structure. The recycling mechanism recycles and reuses the excess release agent through a recycling catheter and piston system.

Benefits of technology

The contact sufficiency and coating uniformity between the release agent and the release paper are improved, the coating effect is enhanced, and the recycling and reuse of excess release agent is realized, reducing processing costs.

Abstract

The invention discloses a papermaking coating device and method for release paper, and relates to the technical field of papermaking coating. The device comprises a U-shaped support, through arrangement and use of the coating mechanism, a coating brush, a first scraper and a second scraper can be driven to perform height adjustment, so that the coating device can adapt to processing of release paper with different thicknesses, the practicability of the coating device is effectively improved, a first rack can be driven to perform circulating reciprocating motion, and the coating efficiency is improved. The Z-shaped connecting rod can drive the T-shaped liquid distributing pipe and the coating brush to move in a circulating and reciprocating mode through the Z-shaped connecting rod, then the release agent can be evenly and comprehensively brushed on the release paper which is dragged to move, in addition, the first scraper and the second scraper conduct scraping and brushing treatment on the brushed release agent in the opposite direction, and the coating efficiency is improved. Therefore, the phenomenon that bubbles are generated between the release agent and the release paper can be effectively avoided, the contact sufficiency and the coating uniformity of the release agent and the release paper can be effectively improved, and the coating effect is effectively improved.
