Abstract

The invention aims to provide an extrusion type coating machine so as to solve the problems of slurry layering and metamorphism and effectively improve the coating precision. The extrusion type coating machine provided by the invention comprises a storage tank, a pump body, a coating head, a control unit and a substrate conveying belt. The coating head is arranged over the substrate conveying belt, and is internally provided with a coating cavity, which is equipped with a feed inlet and a discharge port. The discharge port is disposed at the bottom of the coating cavity. The storage tank, the pump body and the feed inlet of the coating cavity are connected in order through a pipeline. The coating cavity is internally equipped with a pressure sensor. The pressure sensor and the pump body are connected to the control unit. The extrusion type coating machine provided by the invention changes the feeding mode and coating mode of traditional coating machines, the slurry can be always in a flow state, and has very short time to contact the air during coating, so that no packing effect can be generated, and a coating roll, a rubber roll or other parts are not needed. Therefore, the problems of slurry layering and metamorphism are solved, and the coating precision is effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an extrusion coating machine. Background technique

[0002] With the development of electric vehicle technology, people's requirements for the performance of lithium-ion power batteries for vehicles are also increasing, and the substrate coating process in battery production is directly related to the quality of battery performance. At present, most companies in China use transfer coating machines for coating. The trough-type storage and tube-type automatic feeding methods in transfer coating machines have the following disadvantages:

[0003] 1. In the traditional automatic feeding process, the slurry needs to be piled up together. Under the action of the accumulation effect, the lighter components in the slurry will stay at the top of the cone, and the heavier components will move to the bottom of the cone first, so that The slurry is artificially ...
