[0024] When the creasing plate 8 moves downward, the positioning wheel 13 first contacts the cardboard. As the creasing plate 8 continues to move downward, the elastic member 11 is compressed and the reaction force after the compression of the elastic member 11 drives the positioning wheel 13 to press the cardboard to avoid displacement during the creasing process of the cardboard and affect the creasing effect. Before the cardboard rotates through the placement plate 10, the positioning wheel 13 is also operated through the above operation to press the cardboard through the elastic force of the elastic member 11, and the positioning wheel 13 can rotate at the bottom of the elastic member 11 through the rotating shaft 12. When the placement plate 10 rotates, the positioning wheel 13 that presses the cardboard rotates accordingly through the rotating shaft 12, which can effectively avoid the cardboard from deviating when the placement plate 10 rotates.
