The chain plate line uses the standard chain plate as the bearing surface and is driven by the motor reducer; it can be paralleled by multiple rows of chain plates, so that the chain plate conveyor can be made very wide and form a differential speed. The speed difference of multiple rows of chain plates is used to make more Column conveying becomes single-line conveying without squeezing, so as to meet the requirements of single-line conveying for beverage labeling, canning, cleaning and other equipment.
