The stainless steel chain conveyor can meet the requirements of single-line conveying of beverage labeling, filling, cleaning and other equipment. It can also make a single-line into multiple lines and move slowly, thereby generating storage capacity to meet the requirements of sterilization machines, bottle storage platforms, and cold storage. For the large-volume feeding requirements of the bottle machine, we can make the head and tail of the two chain conveyors into an overlapping mixing chain, so that the bottle (can) body is in a dynamic transition state, so that the bottle does not stay on the conveyor line, which can meet Pressure and pressureless delivery of empty and solid bottles.
