Problems solved by technology

[0003] Lithium battery negative electrode homogenization needs to be mixed, but there are the following disadvantages: 1. The homogenized raw materials cannot be continuously added during the stirring process, and different proportions are made, and sufficient mixing cannot be performed, resulting in poor mixing effect; 2. Stir the negative electrode homogenate of the lithium battery again. During the stirring process, hard precipitates are prone to occur, and the precipitates are adsorbed on the inner wall of the equipment, making the homogenate mixing insufficient and affecting the quality of the finished product.

Abstract

The invention discloses a lithium battery cathode homogenate mixer which comprises a bottom plate, a pair of side plates are arranged on two sides of the top surface of the bottom plate, a homogenate cylinder is arranged between the pair of side plates, a pair of fixed cylinders are arranged on two side surfaces of the homogenate cylinder, a transverse shaft is arranged at an eccentric position in the homogenate cylinder, and two end parts of the transverse shaft respectively extend into the fixed cylinders. A stirring assembly is arranged on the transverse shaft; hollow shafts are inserted in the positions, concentric with the transverse shaft, of the inner side walls of the pair of side plates, a square ring is arranged in an inner port of each hollow shaft, a square shaft is inserted in each square ring, the two ends of the transverse shaft are coaxially connected with the inner ends of the pair of square shafts respectively, and a baffle disc is arranged at the outer end of each square shaft. A linkage mechanism is arranged on the outer side face of one side plate. The invention also discloses a use method of the lithium battery negative electrode homogenate mixer. The lithium battery cathode homogenizer is compact in overall structural design, can perform homogenate stirring on lithium battery cathode homogenate, and avoids the phenomenon that residues are adsorbed on the inner wall of equipment.

Description

technical field [0001] The invention relates to the technical field of lithium battery negative electrode homogenization and mixing, in particular to a lithium battery negative electrode homogenization and mixing machine and a use method thereof. Background technique [0002] my country's new energy automobile industry is developing rapidly. Lithium battery is a kind of negative electrode material with lithium metal or lithium alloy, which has become a bottleneck restricting the promotion and popularization of new energy production capacity. The production process of lithium battery usually includes pulping, coating, assembly, and chemical formation. Four steps, during the production process, it is necessary to fully stir the homogenate of the negative electrode of the battery. [0003] Lithium battery negative electrode homogenization needs to be mixed, but there are the following disadvantages: 1. The homogenized raw materials cannot be continuously added during the stirrin...
