The automatic folding tray machine consists of a conveyor, a lifting mechanism, and a tray fork. It is a folding device used for empty mother pallets, with the purpose of stacking/splitting empty pallets and reducing floor space. It is usually used at the exit of empty pallets in automated warehouses. Working principle: After the empty mother tray is in place, the stacking or dismantling operation of the mother tray is completed through the cooperation of the forks on both sides and the lifting platform, thereby achieving automatic disassembly, feeding, and recycling of the tray.
