Description

[0002] With the rapid development of the lithium battery industry, the development of automation in the graphitization industry has been driven. The demand for graphitization equipment in the market has increased, and the mainstream graphitization equipment in the market is the roller kiln. The main process of graphitization automation production equipment is to heat the material at high temperature and graphitize it, and then automatically transport the finished product out of the kiln, so it is very important to smoothly transport the sagger carrying graphite in the kiln. Due to the high temperature in the roller kiln, the conveying rollers used in the roller kiln are usually made of ceramics. The materials are continuously fed and discharged during graphitization. When the kiln is running, the materials are continuously fed in and out of the kiln, and the ceramics will be deformed or broken in the high temperature environment in the kiln for a long time. When the rollers are broken, it is very difficult to pull the rollers out from both sides of the kiln when they need to be replaced. The transmission system needs to be shut down for a long time and a large number of parts need to be disassembled before replacement, but the equipment can only be shut down temporarily, otherwise the materials in the kiln may be unqualified and scrapped. Therefore, it is particularly important to provide a mechanism with short downtime and convenient and fast replacement of rollers. Utility Model Content
