Abstract

The invention discloses a coating mold head with cavity pressure adjusted in a horizontal direction. The coating mold head includes an upper mold head and a lower mold head, a slit coating opening isformed in a front end clipper seam between the upper mold head and the lower mold head, a storing cavity is opened in the lower mold head, the storing cavity communicates with the slit coating opening, a cavity pressure adjustment mechanism is arranged on the upper mold head, and the cavity pressure adjustment mechanism includes a sliding block located in the storing cavity, and a transmission adjustment rod used to make a cam head be connected with the sliding block in a transmission mode. When the transmission adjustment rod rotates, the cam head can drive the sliding block to move in a horizontal direction of coating feeding to adjust the cavity pressure in the storing cavity. The coating mold head is provided with the cavity pressure adjustment mechanism, the cavity pressure in the storing cavity can be flexibly adjusted in real-time in the production process of coating, so that the flow velocity and flow of coating slurry can be adjusted, the coating mold head is provided with a gap adjustment mechanism coordinately, and the real-time adjustment of the flow velocity and flow of the coating slurry can be effectively finished in the production process of the coating.

Description

technical field

[0001] The invention relates to the technical field of coating equipment, in particular to a coating die head capable of adjusting cavity pressure in a horizontal direction. Background technique

[0002] During the production of lithium battery pole pieces, it is necessary to coat the slurry on the pole piece substrate. The surface density uniformity, transverse thickness consistency and accuracy of the coated coating are mainly determined by the slurry flow rate and flow rate before coating, while the flow rate and flow rate of the slurry are mainly determined by the cavity pressure of the material storage chamber and the gap between the coating ports.

[0003] However, in the current coating die head, since the cavity pressure is fixed after the shape and size of the storage cavity are determined, the cavity pressure of the storage cavity cannot be adjusted flexibly, and the coating cannot be adjusted through the flexible adjustment of the cavity pressure o...
