Abstract

The invention discloses an original material fine grinding device for lithium ion battery production and belongs to the technical field of lithium ion battery production. The original material fine grinding device for lithium ion battery production comprises a base and a grinding box. The grinding box is rotatably connected to the base, and the top of the grinding box is connected to a box door. The original material fine grinding device for lithium ion battery production further comprises a rotating shaft. A gear tooth is arranged on the inner wall of a stretching hood, a first gear is fixedly connected to the rotating shaft, a sliding shaft is slidably connected to the base, a second gear is rotatably connected to the sliding shaft, a grinding knife is fixedly connected to the rotating shaft, a plurality of stop dogs are fixedly connected to the inner wall of the grinding box, a gap is reserved between adjacent two stop dogs, and the grinding knife can slide freely in the gap. The original material fine grinding device for lithium ion battery production further comprises a driving part. According to the original material fine grinding device for lithium ion battery production, the grinding box rotates in a reverse direction while the grinding knife rotates and a material is lifted by means of the stop dogs and is located between the grinding knife and the stop dogs, so that afine grinding effect is achieved. By forming a straight slot in the rotating shaft, a fixed water pipe adds water uniformly into the grinding box.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery production, in particular to a fine grinding device for raw materials used in lithium ion battery production. Background technique [0002] Lithium battery refers to the battery containing lithium in the electrochemical system. Lithium battery can be roughly divided into two types: lithium metal battery and lithium ion battery; the negative electrode material of lithium battery is mainly graphite. When producing lithium battery negative electrode, graphite needs to be processed Crushing, screening, mixing and other processing; [0003] Among them, crushing is a relatively important process, which requires uniform particle size and high crushing efficiency; however, the particle size range of the particles crushed by the existing crushing device is relatively large, and many particles do not conform to the The production requirements need to be reprocessed; and it is not convenient to ...
