Roller machine:

In ancient China, the high-turning drum car and the overturned car to carry water are the prototype of modern bucket elevator and scraper conveyor. In the 17th century, aerial ropeway was used to transport bulk materials. In the middle of 19th century, various modern conveyors appeared one after another.

In 1868, the belt conveyor appeared in Britain; In 1887, the screw conveyor appeared in the United States; In 1905, steel belt conveyor appeared in Switzerland; In 1906, inertial conveyors appeared in England and Germany. Since then, conveyor machinery manufacturing, electrical, chemical and metallurgical industry technology progress, constantly improve, gradually by complete the workshop internal transport development to finish within the enterprise, between enterprises and even between urban material handling, become a material handling system an integral part of mechanization and automation.

The power roller table is composed of power roller bucket assembly, aluminum side plate, sheet frame, tie rod, bearing seat, drive device and chain. The unpowered roller table is composed of unpowered roller barrel assembly, aluminum side plate, sheet frame, tie rod and bearing seat. The power roller table is driven by a driving device to drive the traction chain, which drives the sprocket wheel on each power roller barrel to rotate, so as to transport by rotation. An unpowered roller table in which the workpiece is pushed and pulled by a person or the workpiece is squeezed, moving on a free roller.
