Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a wet coating device. Background Art

[0002] Coating machines are mainly used for surface coating production of films, paper, etc. Among them, the coating and glue injection device is the key process of the coating machine. It is generally composed of three parts: a glue tank, a backing wheel and a scraper. It wet-coats a layer of functional adhesives, coatings or inks on the rolled substrate, and then dries and solidifies it before winding it up. In actual operation, the functional adhesives, coatings or inks used in production will contain rubber particles, foreign matter, etc., which will lead to poor appearance if directly put into production, and even damage the coating device. To solve this problem, the functional adhesives, coatings or inks usually need to be stirred at high speed before coating, and then filtered for use.

[0003] Currently, the existing filtration systems are mostly composed of two sub-structures: stirring first and then filtering, which makes it easy for functional adhesives, coatings or inks to have defects such as gelation and phase separation during the static filtration process. In addition, the stirring system and the filtration system are mostly open systems, and bubbles are easily generated during the stirring process, which affects the appearance and quality of the product, reduces production efficiency, and increases production costs.
