Embodiment Construction

[0016] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0017] Such as figure 1 As shown, the coating control valve device disclosed in this implementation is used in coating equipment, including the feed port 3, the feed port 4 and the feed return port 5 connected by the pipeline 6, and the coating valve 1 that controls the feed port 4 And the return valve 2 that controls the return port, the coating valve 1 and the return valve 2 are jointly controlled, that is, when the coating valve 1 is opened, the return valve 2 is closed, and when the coating valve 1 is closed, the return valve 2 Open.

[0018] In this embodiment, the coating valve 1 includes a support body 11, a coating cylinder 12 connected to the lower end of the support body 11, and a coating valve body 13 connected to the upper end of the support body 11. The coating of the coating...

Abstract

The invention relates to a coating control valve device. The coating control valve device comprises a feed inlet, a discharge outlet and a material returning port which are connected through pipelines and further comprises a coating valve controlling the discharge outlet and a material returning valve controlling the material returning port. The coating valve comprises a first supporting body, a coating air cylinder connected to the lower end of the first supporting body and a coating valve body connected to the upper end of the first supporting body, and a coating valve rod of the coating valve body is connected with a connector of the coating air cylinder. The material returning valve comprises a second supporting body, a material returning air cylinder connected to the lower end of the second supporting body and a material returning valve body connected to the upper end of the second supporting body, and a material returning valve rod of the material returning valve body is connected with a connector of the material returning air cylinder. The material returning port is formed in the upper portion of the material valve. According to the coating control valve device, the structural design is reasonable, a whole material returning cavity can be filled with slurry when the slurry is returned, a zone is not prone to being formed, the material returning effect is good, and an unblocked effect is achieved; in addition, the coating valve and the material returning valve are easy to install, not prone to dislocation, high in installation concentricity and small in deviation; and thus, the coating valve and the material returning valve are more stable in working and higher in coating precision and coating quality.

Description

technical field [0001] The invention belongs to the technical field of coating machines, and in particular refers to a coating control valve device for coating machines. Background technique [0002] At present, in the battery production process, coating is an important and indispensable production process, that is, the prepared paste-like viscous slurry is evenly, continuously or intermittently coated on the substrate. In order to control the coating length and ensure the consistency of the coating thickness, a coating control valve is usually used in the coating machine. The coating control valve includes a coating valve and a return valve. When the coating is working normally, the coating valve is opened. The return valve is closed. When the coating is finished and the slurry is whitening, the coating valve is closed and the return valve is opened. [0003] Due to the unreasonable structural design of the return valve of the existing coating control valve device, it is e...
