[0058] Finally, the Z-axis slide continues to move downward, pushing the paper blank out of the box pressing assembly; the negative pressure of the suction cup 14 is released, the box pushing cylinder 15 is controlled to start, and the box pushing plate 22 is used to push the paper box out. The two-axis linear gantry 6 returns to the initial position along the original path to carry out the next cardboard grabbing.
