The pallet lifting mechanism A on the left side rises, and the uppermost pallet on the pallet lifting mechanism A is clamped and fixed by the pallet clamping mechanism A. The pallet supporting mechanism A drives the remaining pallets to descend, and supports the pallet clamped and fixed by the pallet clamping mechanism A through the pallet supporting mechanism A. At the same time, the pallet clamping mechanism A releases the pallet, and the pallet pushing mechanism pushes the pallet from the left pallet supporting mechanism A to the right pallet supporting mechanism B, thereby realizing the transfer of the pallet position. The automatic pallet loading and unloading machine has a small structure size, does not occupy space, and has a simpler structure than existing similar equipment. It can be used as a loading machine and a unloading machine at the same time, and has high versatility.
