The output shaft of the transfer drive motor is connected to the transfer ball screw, driving the transfer ball screw to rotate. The first drive nut 2123 is threadedly engaged with the transfer ball screw to achieve axial movement along the transfer ball screw. The transfer guide rail 2121 is located on both sides of the transfer ball screw. The transfer pallet 2122 is connected to the first drive nut 2123 and can move with the movement of the first drive nut 2123. The transfer pallet 2122 is movably arranged on the transfer guide rail 2121. The transfer guide rail 2121 can support the transfer pallet 2122, making the movement more stable.
