When the pneumatic suction cups 92 suck the uppermost sheet of the support plate 82 to the feeding portion 101, the infrared sensor 84 senses that the height of the stacked sheets on the support plate 82 becomes low, and the infrared sensor 84 controls the elevator 83 to ascend through the controller until the height of the uppermost sheet of the support plate 82 is aligned with the detection angle of the infrared sensor 84, so that the pneumatic suction cups 92 can suck the sheet on the support plate 82 again next time.

The use steps of the creasing machine for making cartons of this embodiment are:

s1, adjusting the distance between the two guide pieces 11 to enable the distance between the two guide pieces 11 to be equal to the width of a paperboard; the distance between the two fixing plates 40 is adjusted so that the distance between the first discharging wheel 41 and the second discharging wheel 42 on the two sides is the same as the width of the paper board. The paper board is ensured to have a proper indentation depth by adjusting the height position of the gear disc 721 according to the thickness of the paper board.

S2, the sheets are stacked on the support plate 82 with the top-most sheet of the support plate 82 aligned with the infrared sensor 84.

S3, the pneumatic slide rail 9 drives the pneumatic suction cups 92 to move, and the pneumatic suction cups 92 absorb the paper boards on the topmost layer of the supporting plate 82 to the feeding part 101; the electric push rod 32 is controlled, and the electric push rod 32 drives the material pushing member 31, so that the paper boards of the feeding portion 101 are pushed into the material pressing channel. When the paper board abuts against the limiting piece 51, the electric push rod 32 controls the material pushing piece 31 to reset.

S4, under the driving of the material pressing motor, the transmission disc 7 rotates, and due to the fact that one end of the moving rod 71 is connected with the eccentric circle of the transmission disc 7 in a rotating mode, one end of the transmission rod 71 carries out eccentric circular motion, and therefore the pressing plate 21 can move in a reciprocating mode along the axial direction of the connecting shaft 22, and pressing marks are carried out on the paper board on the machine base 1.

And S5, after the indentation is finished, the paper board is conveyed out of the machine base 1 under the driving of the first discharging wheel 41 and the second discharging wheel 42.
