Roller chain conveyors use chains as traction and carrier to transport materials. The chain can use ordinary sleeve roller conveyor chains, or other special chains (such as accumulation chains, double-speed chains). The chain conveyor has a large conveying capacity, mainly conveying pallets, large turnover boxes, etc. The conveyor chain has various structures and various accessories, which is easy to realize accumulation and transportation, and can be used as an assembly line or as a storage and transportation of materials.

The power roller table is composed of a power roller barrel assembly, an aluminum side plate, a sheet holder, a tie rod, a bearing seat, a driving device and a chain. The unpowered roller table is composed of unpowered roller barrel components, aluminum side plates, sheet holders, pull rods and bearings. The power roller table is driven by the driving device to drive the traction chain, and the chain drives the sprocket on each power roller barrel to rotate, so that the rotating conveyor works. The unpowered roller table is pushed and pulled by the work piece or the work piece squeezes the work piece, and moves on the free roller.
