[0028] Specific working principle:

[0029] When the device is in use, the pull rod 8 is pulled to drive the clamping plate 10 to move upward, the first spring 9 is compressed, the cardboard is placed under the clamping plate 10 inside the placement box 7, and then the pull rod 8 is released. The first spring 9 pushes the clamping plate 10 to move downward to clamp one end of the cardboard, and the other end of the cardboard is placed on the top surface of the support plate 17, and the cardboard to be cut is moved to just below the cutter 6. The support plate 17 supports the other end of the cardboard, thereby maintaining the horizontal state of the cardboard, and the driving motor 5 is operated to drive the cutter 6 to rotate, and the electric telescopic rod 2 is operated to drive the lifting plate 3 to move downward, and the movement of the lifting plate 3 drives the insertion rod 20 to move downward The lifting plate 3 continues to move downward so that the insertion rod 20 can move toward the inside of the sleeve 19 relative to the sleeve 19, and the second spring 22 is compressed until the cutter 6 contacts the cardboard to cut the cardboard. The rotating plate drives the threaded rod 23 to rotate, which can drive the movable block 24 to move forward and backward, thereby driving the cutter 6 to move forward and backward. After the cutting is completed, the electric telescopic rod 2 is operated to drive the lifting plate 3 to move upward until the lifting plate 3 moves back to its original position. At this time, the insertion rod 20 has been separated from the socket 16.

[0030] When the cardboard needs to be cut with the same width, the servo motor 13 is operated to drive the intermittent gear 14 to rotate. When the saw teeth of the intermittent gear 14 are engaged with the rack 25, the intermittent gear 14 rotates to drive the placement box 7 to move closer to the cutter 6. When the saw teeth of the intermittent gear 14 just disengage from the rack 25, the cardboard to be cut is just moved to the bottom of the cutter 6, and the insertion rod 20 is just aligned with the bottom of the adjacent insertion hole 16. The electric telescopic rod 2 is operated to drive the cutter 6 to move downward, which can facilitate the cutter 6 to cut the cardboard. The continuous rotation of the intermittent gear 14 can drive the saw teeth to intermittently engage with the rack 25, so that the cardboard to be cut is intermittently moved to the bottom of the cutter 6, and the moving distance is the same and the accuracy is high.
