Shaft assembly for lithium battery material production and combination method thereof

Abstract

The invention discloses a shaft assembly for lithium battery material production. The shaft assembly comprises a conveyance shaft, wherein the conveyance shaft comprises a hollow supporting shaft and a wrapping layer wrapping the outer surface of the supporting shaft, the conveyance shaft is sleeved with two rollers, one end of the conveyance shaft is sleeved with a transmission wheel, bearings are arranged between the transmission wheel and the rollers, and bearing seats matched with the bearings are arranged outside the bearings. The shaft assembly for lithium battery material production can meet the use requirement of customized conveyance in special industries and the special requirement of multi-product production, and reduce the potential safety hazard of the use environment; in the production process of the lithium battery material, the low-zinc, low-copper and high-temperature-resistant conveyance requirements can be met, pollution from external metal elements in the raw material conveyance process is avoided, the sintering quality of the raw materials is guaranteed, and the potential safety hazard of battery discharge caused by raw material pollution in the production process is reduced; and the rated conveyance load can be increased only by adjusting the thickness of the coating layer according to the mass of conveyed products, machining of a metal piece is avoided, and the production cost is saved.

Description

technical field [0001] The invention relates to a shaft assembly, in particular to a shaft assembly for lithium battery material production and an assembly method thereof. Background technique [0002] The transmission line is indispensable in industrial production, and it is also a bridge connecting each stand-alone machine and workstation. The traditional transmission method uses metal rollers or belts. With the birth of some special industries, the requirements for transmission lines are getting higher and higher. , specifically including material properties, temperature, efficiency, and cost price.

AI Technical Summary

Problems solved by technology

Lithium battery materials are mainly composed of four major materials: positive electrode material, negative electrode material, separator and electrolyte. In the process of producing positive and negative electrode materials of lithium battery, due to the high temperature of raw materials after sintering, generally above 200 ℃, adopt All of them are transported by metal shafts and rollers. During the process of use, there will be a risk of metal particles, which not only affects the quality of sintering of lithium battery raw materials, but also causes serious battery discharge, which poses a great safety hazard.

In addition, in the actual site, due to the different loads, the metal shaft needs to be processed to different degrees, which increases the overall cost of the equipment.

Lithium battery raw materials need low zinc and low copper in the production process. The use of metal materials can no longer meet the production needs. A new shaft assembly is urgently needed to meet the production and transportation needs.
