an applicator

Abstract

The invention relates to a coater. The coater comprises a base, wherein a cushion plate is fixedly installed on the base, a rack is fixedly installed at the left side of the cushion plate, a drive cylinder is installed on the front part of the rack, the drive cylinder is connected with a guide block, a main action plate is installed on the rear part of the rack in a hinging manner, a transversal folded groove is formed in the main action plate, a brush is slidably installed in the transversal folded groove, an extension plate is welded at the right end of the main action plate, and a lug is slidably installed at the right end of the extension plate; and a transfer motor is installed at the right side of the cushion plate, the transfer motor is connected with a rotating plate frame, a waist-shaped groove in slide fit with the lug is formed in the rotating plate frame, and a limit frame enabling the extension plate to carry out 90-degree limit rotation is fixedly installed at the rear side of the cushion plate. The coater disclosed by the invention is simple to control and high in automation degree; a cylinder thrust is cooperated by virtue of a double-angle transmission principle and gravity action to realize the purpose of controlling the brush to alternately carry out backward slide and return motion; and the coater is simple to control, energy-saving and capable of facilitating the replenishing of a protective paint.

Description

technical field [0001] The present invention relates to a mechanical device, in particular an applicator. Background technique [0002] Boss-shaped parts, its essence is to add a strip-shaped boss on the left and right sides of the upper part of the rectangular part to facilitate extraction and transportation. In practical applications, the lower end of the boss-shaped part is often used for assembly or as a The use of pressed parts is more widely used than the other surfaces of boss-shaped parts. Therefore, during production and processing, people need to grind and apply protective paint to the bottom surface of boss-shaped parts, but in practice, Due to the large area of ​​the rectangular surface at the lower end of the boss-shaped parts, the manual smearing method consumes a lot of labor. Even if the boss-shaped parts are put into the processing line, it needs to be painted at any time during the process of painting. It is very inconvenient to replenish the protective pa...
