left drag conveyor

This paper begins with the analysis of chain driving motion characteristics to find the causes to the scratching of paint film on the bottom surface of the work pieces by the load bearing part of the chain plate conveyer on the steel pretreatment line,and several rules in structural design of the chain plate conveyer are put forward.
