The pallet lift platform is used to send the positioned empty cans to the can unloading height When the empty can cans are unloaded, the empty pallets will fall and be put onto the conveyor. the motor drives the chain wheel and chain device to push the cans, and then the full piles of the empty can will be pushed onto the net conveyor, and will return to the preparation position and continue to push out the next pile. All action positioning is controlled by the photoelectric switch. The can unloading with continuous actions or single circulating mode can be selected. The pile feeding direction, can discharging direction and operation panel position of the machine can be flexibly changed according to user requirement.
