the method comprises the following steps: the motor (512) is electrified to rotate to drive the second fixed shaft (508) to rotate, then the second gear (509) drives the second racks (510) on the two sides to move, so that the pull rods (404) on the two sides are driven to move, or the hand wheel (507) is rotated to drive the worm (505) to rotate, and further the worm wheel (504) drives the first gear (502) on the outer side of the first fixed shaft (501) to rotate, so that the first racks (503) drive the pull rods (404) on the two sides to move;
step two: the pull rods (404) on the two sides move reversely at the same time, so that the guide wheels (402) on the outer side are driven to move and adjust, the guide wheels (402) are always located at the central position, the paperboard printing machine is convenient to be suitable for paperboards to be printed with different widths, the paperboards are centered, printing and spraying are convenient to perform, meanwhile, when the guide wheels (402) on the outer side are adjusted, the two guide wheels (402) on the inner side are also approximately located at the central position due to the action of the compression springs (403), and the feeding effect of the paperboards is ensured;
step three: when guide pulley (402) in the outside removed, under reset spring (303), sleeve (301) and loop bar (302) effect, can make L template (306) can remove along with the removal of guide pulley (402), and then can carry out better spacing effect to the side of cardboard, thereby the better conveying effect of cardboard has been guaranteed, the setting of first ball (307) and second ball (308), can effectual reduction friction, guarantee the stable operation of equipment, at last when using, to the outside access rotation power device of fixed section of thick bamboo (6) can.
