Weighing and powder mixing system for producing tubular positive plates

Abstract

The invention relates to a production device for electrodes consisting of active materials, in particular to a weighing and powder mixing system for producing tubular positive plates. The weighing and powder mixing system for producing the tubular positive plates comprises at least two material supply assemblies, a weighing device, a powder mixing device and a control system, wherein the weighing device is arranged below a discharging opening of the material supply assemblies and comprises a hopper; a weighing sensor corresponds to the hopper; a discharging valve is arranged at an outlet of the bottom of the hopper; the outlet of the bottom of the hopper communicates with the powder mixing device through a mixed powder inlet tube; the powder mixing device comprises a powder mixing barrel; a mixed powder feeding opening is formed in the powder mixing barrel and corresponds to the mixed powder inlet tube; the mixed powder feeding opening is provided with a switch valve; a stirring shaft is arranged in the powder mixing barrel; one end of the stirring shaft extends out of the powder mixing barrel and is driven to rotate by a driving device; and the material supply assemblies, the weighing sensor, the discharging valve, the switch valve and the driving device are connected to a control system. By the weighing and powder mixing system for producing the tubular positive plates, powder can be fully mixed automatically, and human bodies are prevented from being in direct contact with lead dust.

Description

technical field [0001] The invention relates to a production device of an electrode composed of active materials, in particular to a weighing powder mixing system for the production of a tubular positive plate. Background technique [0002] In the production process of the tubular positive plate, it is necessary to fill the positive plate with active materials. The composition ratio of the active materials varies with different battery models. Before filling, it is necessary to fully mix the raw materials with a suitable ratio. Manual mixing, on the one hand, the lead dust directly contacts the operator, which is harmful to the health of the operator, and the manual labor intensity is high; on the other hand, the efficiency of manual weighing is low, and the mixing effect is not uniform enough. Contents of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a weighing and mixing system for the production...
