[0002] A chain conveyor is a conveying device that uses standard chain plates as the load-bearing surface and is powered by a motor reducer. A chain conveyor consists of a power unit (motor), drive shaft, rollers, tensioning device, sprockets, chains, bearings, lubricants, and chain plates. The main component that drives the material is the chain, which uses its reciprocating motion to provide traction. The chain is generally composed of outer and inner links strung together. The outer links are formed by two outer chain plates and two pins, while the inner links are formed by two inner chain plates, two sleeves, and two rollers.

[0003] When producing inner chain links, the inner link plate on one side is usually pressed into the sleeve, and then manually turned over to press the inner link plate on the other side. Each inner link plate needs to be clamped twice, resulting in low efficiency in inner chain link assembly. For large orders, the inner chain link assembly time is too long, and there is often a phenomenon of supply exceeding demand, resulting in production delays, inability to meet large-scale production needs, and affecting enterprise development.
