Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1-5 As shown, a cutting device for packaging box production includes an outer body 1; the top end of the inner part of the outer body 1 is fixedly connected to the top end of an electric push rod 2, and a fixing adjustment mechanism is provided inside the outer body 1. The fixed adjustment mechanism includes a fixed plate 10, which is located at the bottom of the electric push rod 2. The top of the fixed plate 10 is fixedly connected to the bottom of the electric push rod 2. The bottom of the fixed plate 10 is fixedly connected to the top of the cutting blade 11 near the left side. A placement platform 12 is provided inside the main body 1 of the device near the bottom. A cutting groove 13 is provided at the top of the placement platform 12. A positioning block 14 is also provided at the top of the placement platform 12 near the corner. The top of the placement platform 12 is fixedly connected to the bottom of the positioning block 14. The positioning block 14 is square in design. During operation, the cardboard of the packaging box is placed inside the placement platform 12. The positioning block 14 near the corner of the placement platform 12 can effectively position the cardboard to prevent displacement inside the placement platform 12. Then, the electric push rod 2 is started, which drives the fixing plate 10 to move downward. When the fixing plate 10 moves downward, it drives the cutting blade 11 to move downward at the same time until the bottom end of the cutting blade 11 contacts the cardboard and continues to move downward until the bottom end of the cutting blade 11 cuts the edge of the cardboard. After cutting, the bottom end of the cutting blade 11 is inserted into the cutting groove 13.

[0017] Furthermore, sleeve rods 15 are also provided at the front and rear ends of the right side of the bottom of the fixing plate 10, and the bottom of the fixing plate 10 is fixedly connected to the top of the sleeve rod 15. A movable rod 16 is inserted inside the sleeve rod 15, and the sleeve rod 15 is slidably connected to the movable rod 16. The movable rod 16 is a round rod design, and the bottom of the movable rod 16 is fixedly connected to the top of the positioning plate 17. During operation, the fixed plate 10 moves downward, causing the bottom end of the positioning plate 17 to contact the surface of the paper shell first. The positioning plate 17 applies pressure to the paper shell to ensure that the paper shell does not warp during cutting. As the fixed plate 10 continues to move downward, it causes the sleeve rod 15 to move downward along the outside of the moving rod 16.

[0018] Furthermore, sliders 18 are also provided at the front and rear ends of the moving rod 16 near the top, and one end of the slider 18 is fixedly connected to the outer side of the moving rod 16. A groove 19 is provided on the outer side of the sleeve rod 15, and the other end of the slider 18 is inserted into the groove 19. The slider 18 is slidably connected to the groove 19. The slider 18 is square in design. During operation, the sleeve rod 15 moves downward along the outside of the moving rod 16, causing the slide groove 19 to move along the outside of the slider 18.

[0019] Furthermore, reset springs 20 are also provided on the left and right sides of the bottom end of the fixing plate 10. The top end of the reset spring 20 is fixedly connected to the bottom end of the fixing plate 10, and the bottom end of the reset spring 20 is fixedly connected to the top end of the positioning plate 17. During operation, the fixed plate 10 moves downward, which will compress the return springs 20 on both sides to retract.

[0020] Furthermore, the bottom of the outer body 1 is fixedly connected to the bottom of the motor 21 near the left side, the top of the motor 21 is fixedly connected to the bottom of the first gear 22, the first gear 22 is meshed with the second gear 23, the inside of the second gear 23 is fixedly connected to the outside of the rotating block 24, and the top of the rotating block 24 is fixedly connected to the bottom of the placement platform 12. When in operation, the motor 21 is started, which drives the first gear 22 to rotate. When the first gear 22 rotates, it drives the second gear 23 and the rotating block 24 to rotate synchronously. When the rotating block 24 rotates, it drives the placement table 12 to rotate, thereby driving the paper shell to rotate and adjust the cutting end.

[0021] Furthermore, a sleeve block 25 is fitted on the outer side of the bottom end of the rotating block 24, and the rotating block 24 is rotatably connected to the sleeve block 25. The bottom end of the sleeve block 25 is fixedly connected to the bottom end of the inner body 1 of the device, and the inner wall of the sleeve block 25 is circular. When in operation, the rotating block 24 rotates, and will rotate along the inside of the sleeve block 25.

[0022] Working principle: First, the cardboard box is placed inside the placement platform 12. The positioning block 14 near the corner of the placement platform 12 effectively positions the cardboard box to prevent displacement within the platform 12. Then, the electric push rod 2 is activated, causing the fixing plate 10 to move downwards. As the fixing plate 10 moves downwards, it also moves the cutting blade 11 downwards simultaneously until the bottom of the cutting blade 11 contacts the cardboard box. It continues to move downwards until the bottom of the cutting blade 11 cuts the edge of the cardboard box. After cutting, the bottom of the cutting blade 11 inserts into the cutting groove 13. Simultaneously, as the fixing plate 10 moves downwards, it also causes the bottom of the positioning plate 17 to contact the surface of the cardboard box first. The positioning plate 17 applies pressure to the cardboard box to ensure that the cardboard box does not shift during cutting. When the edge warps and the fixing plate 10 continues to move downward, it drives the sleeve rod 15 to move downward along the outside of the moving rod 16. At the same time, as the sleeve rod 15 moves downward along the outside of the moving rod 16, it drives the slide groove 19 to move along the outside of the slider 18. Simultaneously, the fixing plate 10 moves downward, which will compress the return springs 20 on both sides to retract until the cutting is completed. When it is necessary to adjust the cutting end, the motor 21 is started, which drives the first gear 22 to rotate. When the first gear 22 rotates, it drives the second gear 23 and the rotating block 24 to rotate synchronously. When the rotating block 24 rotates, it drives the placement table 12 to rotate, thereby driving the cardboard to rotate and adjust the cutting end. When the rotating block 24 rotates, it will rotate along the inside of the sleeve block 25.
