[0043] Working principle: After the cardboard box is printed by the printer 2, it is dried by the dryer 3 to ensure the printing effect. When sorting the cardboard boxes with printing defects, the electric push rod 6 is lowered to connect the connecting seat 7 and the mounting plate 8, and the suction cup 21 sucks up the cardboard boxes with printing defects. When the mounting plate 8 descends, the fixed column 9 at one end will be affected by the square column 17 and stand up. The square column 17 just contacts the upper part of the fixed column 9 when a fixed column 9 falls, and can guide the fixed column 9 to stand up. And the two fixed columns 9 will be linked due to the influence of the pulling plate 15 and the rotating piece 16, so that the two fixed columns 9 both stand up. The bottom plate 1 itself is also provided with two notches just allowing the two fixed columns 9 to pass through, so that the fixed columns 9 will not be blocked by the bottom plate 1, avoiding movement interference. When the mounting plate 8 rises, the fixed column 9 is separated from the square column 17, and the spring 12 will pull the sliding sleeve 13, thereby pulling the connecting piece 14 and the lifter 10, so that the lifter 10 drives the round wheel 18 to lift the bottom end of the cardboard box, so that the suction of the suction cup 21 on the cardboard box becomes firmer, ensuring the stability of the adsorption force of the suction cup 21 and avoiding the cardboard box from detaching or unstable rejection operation.

[0044] When the suction cup 21 needs to be replaced, hold the suction cup 21 by hand and lift it upward, so that the suction cup 21 drives the clamping block 22, and the clamping block 22 follows the track of the fixed cavity 20, so that the clamping block 22 is separated from the fixed cavity 20. At this time, the suction cup 21 can be taken out from the placement groove 19. Insert the new suction cup 21 with the clamping block 22 into the interior of the placement groove 19, and let the clamping block 22 follow the track of the fixed cavity 20 and re-engage with the clamping block 22. When the clamping block 22 is re-engaged with the fixed cavity 20, release the hand holding the suction cup 21, and the support leg 24 will push the suction cup 21 and drive the clamping block 22 to firmly engage with the fixed cavity 20, thus completing the replacement of the suction cup 21. By making the suction cup 21 drive the clamping block 22 to engage and disengage with the fixed cavity 20, the suction cup 21 can be quickly replaced, making the replacement process of the suction cup 21 more convenient and improving the maintenance efficiency of the suction cup 21.
