Powdery material feeding system for preparation of lithium battery core

Abstract

The invention discloses a powdery material feeding system for preparation of a lithium battery core. The system comprises a fan, an air pipe, a first filter, a conveying pipeline, a high-level material-level meter, an air inlet electromagnetic valve, a material storage tank, a first bracket, a first material discharging electromagnetic valve, a first collecting assembly, a transition material bin,a material feeding electromagnetic valve, a first air inlet assembly, a first weighing sensor, a second bracket, a second material discharging electromagnetic valve, a second collecting assembly, a third bracket, an air storage tank, a second air inlet assembly, a first powdery material electromagnetic valve, a fourth bracket, a stirring device, a second powdery material electromagnetic valve, athird powdery material electromagnetic valve and a PLC module. According to the system, the transition material bin is used for connecting the material storage tank with the stirring device, the material feeding amount is controlled conveniently, precise processing is achieved, intensive collection is facilitated, a powdery material can be recycled, and the cost is reduced; whether the powdery material is wasted or not can be determined, which part of the powder material is wasted the most can be obtained, damaged positions can be found conveniently and timely, and larger losses are avoided intime; and disassembly, maintenance and cleaning are facilitated, and maintenance is convenient.

Description

technical field [0001] The invention relates to a lithium battery preparation device, in particular to a powder material feeding system for preparing lithium battery cells. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. The finished lithium battery consists of two main parts, the lithium battery core and the protective plate. The lithium battery core is mainly composed of a positive plate, a diaphragm, a negative plate, and an electrolyte; the positive plate, the diaphragm, and the negative plate are wound or laminated, packaged, and filled with electrolyte , After packaging, it is made into a battery cell. [0003] In the preparation process of lithium battery, the quality of lithium battery core directly determines t...

AI Technical Summary

Problems solved by technology

The existing powdery material feeding system used to prepare lithium battery cells is not perfect, which makes part of the raw material loss and waste during the feeding process, which is not easy to recycle, greatly increases the production cost, and is not easy to clean, which is not conducive to disassembly and installation during maintenance
