Coating die head, coating device and battery production device

The utility model relates to a coating die head, a coating device and a battery production device. A coating die head comprises a die head body and at least one adjusting assembly. A containing cavity used for containing slurry is formed in the die head body, and a coating slit which communicates with the containing cavity and extends in the first direction is further formed in the die head body. Each adjusting assembly comprises a flow adjusting part which is arranged on the die head body in a penetrating mode in the second direction and can penetrate into the coating slot, and the flow adjusting parts are configured to be capable of moving relative to the die head body in the second direction. Wherein the first direction and the second direction intersect with each other. According to the coating die head, the flow of the slurry flowing out of the coating slit can be adjusted, and the adjusted flow adjusting piece is not influenced by the environment, so that the slurry can stably flow out of the coating sl
