Background

The conveyer can be provided with a chain conveyer belt for conveying articles. Chain conveyors are generally classified into chain, chain plate, chain mesh, and slat types. The chain conveyor belt is generally driven by a drive gear, guided by a driven gear and reversed in order to maintain tension and run it on the machine frame, and the belt is maintained in good contact with the drive and driven gears by a tensioner. The conveyer is also provided with supporting rollers and a supporting structure flat plate, so that the conveyer belt can bear the weight of conveyed articles. The belt is formed by a plurality of belt sections which are hinged with each other, and the belt must be accurately corrected during manufacturing and installation so as to avoid the meandering offset of the belt during movement.
