The lower surface of the limit seat 13 is fixedly connected to the upper surface of the fixed frame 5. One end of the limit column 14 is fixedly connected to the outer wall of the pushing plate 12. The outer wall of the limit column 14 is slidably connected to the inside of the limit seat 13;

[0025] Specifically, starting the rotation of the electric roller 2 can cause the conveyor belt 3 to rotate, thereby enabling the transportation of cardboard boxes. The cardboard boxes can be separated by the partition plate 4. The conveying frame 1 can fix the fixing frame 5. The fixing frame 5 can fix the cylinder 6. The cylinder 6 can move. The slide rail 9 can guide the movement of the slider 10. The connecting bar 8 can connect the moving block 11. The moving block 11 can fix the pushing plate 12. When the moving block 11 moves inward, it will drive the pushing plate 12 to move and align the cardboard boxes transported above the conveyor belt 3. The limiting component composed of the limiting post 14 and the limiting seat 13 can ensure that the pushing plate 12 remains horizontal during movement.

[0026] Refer to Figure 1 、 Figure 3 and Figure 4 , a fixed frame 15 is fixedly connected to the outer wall of the conveying frame 1, and a motor 16 is fixedly connected to the outer wall of the fixed frame 15; the output end of the motor 16 is fixedly connected to a first rotating column 17, and the outer wall of the first rotating column 17 is rotatably connected inside the fixed frame 15; a pressing roller 18 is fixedly connected to the outer wall of the first rotating column 17, and a first gear 19 is fixedly connected to the outer wall of the first rotating column 17; a second rotating column 20 is rotatably connected inside the fixed frame 15, a second gear 21 is fixedly connected to the outer wall of the second rotating column 20, the outer wall of the second gear 21 is meshed with the outer wall of the first gear 19, and a plurality of threaded holes 22 are provided on the outer wall of the second rotating column 20;

[0027] Specifically, starting the motor 16 causes the first rotating column 17 to rotate. The rotation of the first rotating column 17 drives the pressing roller 18 to rotate, and also drives the first gear 19 to rotate, thereby causing the meshed second gear 21 to rotate. The rotation of the second gear 21 causes the second rotating column 20 to rotate and simultaneously drives the first cutting knife 23 and the second cutting knife 25 to rotate. At this time, the cardboard box can be rolled in and cut and scored.

[0028] Refer to Figure 1 、 Figure 3 and Figure 4 , a first cutting knife 23 is slidably connected to the outer wall of the second rotating column 20. A first fixing bolt 24 is threadedly connected inside the first cutting knife 23, and the outer wall of the first fixing bolt 24 is threadedly connected to the inner wall of the threaded hole 22; a second cutting knife 25 is slidably connected to the outer wall of the second rotating column 20. A second fixing bolt 26 is threadedly connected inside the second cutting knife 25, and the outer wall of the second fixing bolt 26 is threadedly connected to the inner wall of the threaded hole 22;

[0029] Specifically, by sliding the first fixing bolt 24 out of the inner wall of the threaded hole 22 and sliding the second fixing bolt 26 out of the inner wall of the threaded hole 22, the distance between the first cutting knife 23 and the second cutting knife 25 can be adjusted by causing the first cutting knife 23 to slide on the outer wall of the second rotating column 20 and causing the second cutting knife 25 to slide on the outer wall of the second rotating column 20.

[0030] Working principle: When the device needs to be used, only need to start the electric roller 2 first to make the conveyor belt 3 rotate, and then place the cardboard box to be processed between the two partition plates 4. After placing it, start the air cylinder 6. When the air cylinder 6 starts, it will cause the L-shaped block 7 to move towards the direction of the air cylinder 6, and then make the connecting bar 8 rotate on the upper surface of the L-shaped block 7 and rotate on the lower surface of the moving block 11 to pull the moving block 11 to drive the slider 10 to slide on the lower surface of the slide rail 9. The movement of the moving block 11 drives the push plate 12 to move inward, so as to ensure that the cardboard box in the process of transportation remains in a horizontal position without deviation, reduce the die-cutting error caused by position deviation, avoid the appearance of defective products, improve the qualification rate, and enhance the production stability. When the cardboard box in the horizontal state is transported to the end, start the motor 16. The start of the motor 16 causes the first rotating column 17 to rotate. The first rotating column 17 rotates inside the fixed frame 15. When the first rotating column 17 rotates, it will also drive the pressure roller 18 to rotate. At the same time, the rotation of the first rotating column 17 also drives the first gear 19 to rotate. The rotation of the first gear 19 drives the second gear 21 to rotate. When the second gear 21 rotates, it causes the second rotating column 20 to rotate inside the fixed frame 15, and at the same time drives the first cutting knife 23 and the second cutting knife 25 to rotate, so that the cardboard box can be rolled in and cut. When it is necessary to adjust the distance between the second cutting knife 25 and the first cutting knife 23, only need to slide the first fixing bolt 24 out of the inner wall of the threaded hole 22, then slide the second fixing bolt 26 out of the inner wall of the threaded hole 22, and then slide the first cutting knife 23 and the second cutting knife 25 along the outer wall of the second rotating column 20 to adjust them to the required cutting distance. Then, fix the first cutting knife 23 with the first fixing bolt 24 and fix the second cutting knife 25 with the second fixing bolt 26 to the adjusted position, so as to achieve the effect of adjusting the distance between the first cutting knife 23 and the second cutting knife 25, and then can adapt to the needs of different specifications of cardboard boxes and increase the production flexibility.

[0031] 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 described 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.
