Coil bar coater capable of controlling coating weight

Abstract

The invention discloses a coil bar coater capable of controlling the coating weight, and relates to the technical field of coil bar coater. The coil bar coater comprises a coating assembly, a handle and a charging barrel, the coating assembly comprises a coating body internally provided with a coating liquid groove, the coating body is provided with a feeding hole and a discharging groove which communicate with the coating liquid groove, a bar body is arranged in the coating liquid groove, an elastic piece connected with the rod body is mounted in the coating body, and the elastic piece applies elastic force for enabling the rod body to move towards the direction of the discharging groove, so that the rod body clamps the discharging groove; the handle is connected with the coating assembly; and the charging barrel is provided with a discharging hole communicating with the feeding hole, and a piston is arranged in the charging barrel and used for outputting the coating in the charging barrel from the discharging hole. According to the coil bar coater capable of controlling the coating weight, materials can be conveniently and uniformly added on the surface of a base material, and the problems of non-uniform coating thickness and the like caused by human factors can be solved.

Description

technical field [0001] The invention relates to the technical field of wire bar coaters, in particular to a wire bar coater with controllable coating amount. Background technique [0002] A wire bar coater is a machine that can evenly apply coatings on the surface of a substrate to form a solid continuous film. The wire bar coaters on the market mainly include wire-wound bar coaters and extrusion-type bar coaters. Although the working principles are different, they are all used to coat wet films of specified thickness. The wire bar coater has the advantages of small size, light weight, simple operation, and easy cleaning, so it is loved by people. [0003] When using a wire bar coater to prepare a coating, it is necessary to pour paint on the surface of the treated substrate in advance every time. If the paint poured on the surface of the substrate is not uniform, it will lead to the side with less paint when scraping. Lack of material will affect the effect of coating fil...
