What is the working principle of the unpowered roller conveyor line?

The driving roller is driven by the motor through the reducer, and the conveyor belt is dragged by the friction between the driving roller and the conveyor belt. The drive drum is generally installed at the discharge end to increase the traction force and facilitate dragging. The material is fed from the feeding end, falls on the rotating conveyor belt, and is discharged from the unloading end of the conveying bag by means of the friction of the conveyor belt. The principle of the single-chain roller conveyor is that the roller is driven by an endless chain, and the chain runs in a special guide rail, which has the characteristics of easy installation and low noise. The single-sprocket drum is driven by a large cycle, the double-sprocket drum is driven by a small cycle, and other driving modes are used for light-duty conveying occasions. It is suitable for conveying all kinds of boxes, bags, pallets and other objects. Bulk materials, small items or irregular items need to be transported on pallets or in turnover boxes.
