Both air inlet ends of the suction device 38 are fixed with retractable hoses 39. The horizontal section of the retractable hose 39 is a plastic retractable tube, and the bending part of the retractable hose 39 is a metal tube. The output ends of the two retractable hoses 39 are fixed with inner hollow plates 310, and the lower end of the inner hollow plates 310 is fixed with two suction cups 311.

After the bidirectional screw 36 is rotated, the two sliding frames 37 can move in relative or opposite directions, so that the device can adjust the distance between the two inner hollow plates 310 to a suitable position according to the size of the paper before operation. Then the first electric push rod 34 drives the entire loading frame 35 to descend, and the suction device 38 is started at the same time, so that the suction cup 311 can contact the paperboard and the paperboard can be moved. The board is adsorbed onto the suction cup 311, and then the first electric push rod 34 retracts to reset the loading frame 35, and at the same time the first motor 32 is started.

After the cardboard is placed on the placement plate 41, the second electric push rod 46 drives the limit frame 47 to descend, so that the pressure plate 49 is against the middle of the cardboard, and then the two micro motors 44 drive the bending plate 45 to flip, so as to fold the cardboard. After folding, the micro motor 44 drives in the reverse direction to reset the bending plate 45, and at the same time the second motor 42 drives the disc 43 to rotate, so that the cardboard between the disc 43 and the pressure plate 49 rotates, which is convenient for folding the other two ends of the cardboard.
