Automatic powdering box for anode of secondary battery

Abstract

The invention relates to an automatic powdering box for the anode of a secondary battery, which comprises a box body; a powder inlet box guide wheel is arranged in the box body; a first coarse coarse brush, a second coarse hard brush, a first soft brush and a second soft brush are arranged above the powder inlet box guide wheel; the end parts of a first rotating shaft, a third rotating shaft and a fourth rotating shaft are all provided with driven sprockets, and a drive sprocket and a first tension sprocket are arranged below one end of the first rotating shaft; the drive sprocket is connected with the driven sprockets corresponding to the first rotating shaft, the third rotating shaft and the fourth rotating shaft by using a first chain; and one end of a second rotating shaft away from the drive sprocket is provided with a driven sprocket, the lower part of the second rotating shaft corresponding to the driven sprocket is provided with a second tension sprocket, and the second tension sprocket is connected with the driven sprockets corresponding to the first rotating shaft and the second rotating shaft by using a second chain. The invention has simple structure, is convenient to maintain, shortens the technological process of anode film production, improves the production efficiency, and reduces the production cost.

Description

technical field [0001] The invention relates to a secondary battery positive electrode sheet production equipment, in particular to a secondary battery positive electrode automatic powder feeding box, which belongs to the technical field of battery manufacturing machinery. Background technique [0002] The positive electrode is one of the indispensable key components of the secondary battery. For a long time, the positive electrode of the secondary battery has been made by the water process, from the sintering process of pulping, sintering, and static impregnation to the nickel foam extrusion, pulping, drying, rolling, and powder cleaning processes. The relevant equipment is nothing more than a gluing machine, a pulp mixing machine, a pulping furnace, a sintering furnace, a dipping tank, a powder cleaning machine, etc. Although it has been improved several times over the years, it is only improved from a certain process step, and it has not jumped out of the original scale. ...

AI Technical Summary

Problems solved by technology

Using these processes and equipment has a long production cycle, difficult process control, low automation, high energy consumption, and high use and maintenance costs. This labor-intensive positive electrode production process and equipment seriously restricts our secondary battery capacity. development, and does not meet the development trend of low-carbon economy and the requirements of green energy
