[0032] A first slide rod 20 is slidably connected to the upper end of the sliding seat 21. Both ends of the first slide rod 20 are fixedly connected to the upper ends of two groups of first rotating seats 19. The sliding seat 21 is restricted by the first slide rod 20 to prevent the sliding seat 21 from rotating with the second threaded rod 26, so that the sliding seat 21 can only slide along the first slide rod 20 and the second threaded rod 26. One side of the upper end of a group of support rods 18 is fixedly connected with a first mounting seat 24. The middle of the first mounting seat 24 is fixedly connected with a second motor 25. The output end of the second motor 25 is fixedly connected to one end of the second threaded rod 26. The second threaded rod 26 is driven to rotate by the second motor 25, so that the sliding seat 21 can slide along the second threaded rod 26. Both sides of the upper surface of the base 1 are fixedly connected with two groups of side plates 3, and the length of the side plates 3 on one side is greater than the length of the side plates 3 on the other side. Multiple cardboard sheets are stacked together and slide into the upper surface of the bearing plate 2 from the side with the shorter side plates 3. The upper surface of the bearing plate 2 is flush with the upper surface of the base 1. Both ends of the upper surface of the bearing plate 2 are fixedly connected with baffles 6. The cardboard sheets can be pushed from the upper surface of the base 1 to the upper surface of the bearing plate 2. One end inside the base 1 is fixedly connected with a first motor 10. The output end of the first motor 10 is fixedly connected with a first threaded rod 11. A sliding block 12 is threadedly connected to the surface of the first threaded rod 11 shown.

The fixed block 17 slides along the second slide rod 28 and cooperates with the third threaded rod 31 to move the fixed block 17 with the pressing plate 16, thereby changing the punching position.

[0033] Working principle: When in use, the device is controlled by an external controller to work. Stack multiple groups of cardboard on one side of the upper surface of the base 1. Drive the first threaded rod 11 to rotate clockwise by the first motor 10, so that the sliding block 12 drives the bearing plate 2 to move along the first threaded rod 11 towards one end of the base 1. When the sliding block 12 moves to the top, the first motor 10 stops rotating. Push the cardboard to make it slide onto the upper surface of the bearing plate 2. Through two groups of baffles 6 and one group of side plates 3, the cardboard is neatly stacked on the upper surface of the bearing plate 2. Then the first motor 10 drives the first threaded rod 11 to rotate counterclockwise, so that the sliding block 12 drives the bearing plate 2 to slide towards the middle of the base 1. During the sliding process, side plates 3 are blocked on both sides of the bearing plate 2. Through the side plates 3 and the baffles 6, it can be avoided that the position of the cardboard shifts and they are not aligned with each other during the movement of the bearing plate 2. When the bearing plate 2 moves to the middle of the base 1, two groups of sliding plates 7 are blocked on both sides of the bearing plate 2, playing the same role as the side plates 3. Then, according to the punching position, adjust the position of the through hole on the pressing plate 16. Drive the third threaded rod 31 by the third motor 30 to make the fixed block 17 drive the pressing plate 16 to move. Drive the third threaded rod 31 to rotate by the third motor 30 to make the fixed block 17 drive the pressing plate 16 to move, thereby adjusting the punching position. When the fixed block 17 moves, drive the second cylinder 22 to move through the support rod 18, the first rotating seat 19, the first slide rod 20 and the sliding seat 21, so that the punching knife 23 is always above the through hole. Drive the second threaded rod 26 to rotate by the second motor 25 to make the sliding seat 21 drive the second cylinder 22 to move, thereby accurately moving the punching knife 23 directly above the punching position, enabling the device to be suitable for punching at various positions. When punching, the first cylinder 14 pushes the cross plate 15 downward. The two ends of the cross plate 15 will squeeze the sliding plates 7 and push the sliding plates 7 into the base 1. At the same time, the baffle 6 will insert into the fixed block 17, so that the pressing plate 16 can press on the surface of the cardboard to avoid the cardboard from cracking during punching. Push the punching knife 23 downward by the second cylinder 22 to insert the punching knife 23 into the through hole to punch multiple groups of cardboard, and the positions of the punched holes are the same.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
