Detailed implementation manners

[0034] The following will combine the attached Figures 1-7 drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Embodiment:

[0036] As Figures 1 to 7 shown, a carton cardboard slitting device includes an operating table 11. An overhead frame 12 is installed on the operating table 11. A lifting guillotine 13 for slitting the cardboard left and right is installed on the overhead frame 12. A driving mechanism for driving the lifting guillotine 13 to move up and down is arranged on the overhead frame 12;

[0037] On the side of the operating table 11 far from the overhead frame 12, mounting brackets 14 are symmetrically arranged front and back. A circular knife 15 for slitting the cardboard front and back is installed on the mounting brackets 14. A first servo motor 16 for driving the circular knife 15 to rotate is arranged on the mounting brackets 14;

[0038] A waste cutting mechanism is arranged on the operating table 11 outside the circular knife 15. A waste slot 17 is opened on the operating table 11. The waste slot 17 is located between the circular knife 15 and the waste cutting mechanism;

[0039] A number of conveyor rollers 18 driven by motors are installed on both the left and right sides of the overhead frame 12 and on the right side of the circular knife 15. The cardboard moves on the operating table 11 through the conveyor rollers 18. Since the driving mechanism of the conveyor rollers 18 is well-known to those skilled in the art, it will not be described in detail here, and the driving mechanism of the conveyor rollers 18 is also omitted in the drawings. Moreover, in the present utility model, a number of the conveyor rollers 18 form a number of roller groups, and there are gaps between each roller group. The size of the cardboard after slitting by this device should be larger than the gaps between each roller group to ensure that the conveyor rollers 18 can drive the slit cardboard to move.

[0040] The working principle of the present utility model is as follows: The cardboard to be slit is driven from right to left by the conveyor rollers 18. During the movement of the cardboard, the cardboard contacts the circular knife 15. The circular knife 15 cuts the front and back ends of the cardboard. The waste paper generated by the cutting is cut off by the waste paper cutting mechanism and falls into the waste slot 17. The cardboard initially cut by the circular knife 15 continues to move left. When passing under the lifting guillotine 13, the lifting guillotine 13 moves downward and cuts the left and right ends of the cardboard, thereby slitting the cardboard into the required size, eliminating the process of transferring the cardboard to another cutting production line and effectively improving the production efficiency.

[0041] Moreover, an emergency stop button 28 is arranged on the mounting bracket 14. When a failure occurs in the circular knife 15 or the waste paper cutting mechanism, the operator can press the emergency stop button to stop the circular knife 15 or the waste paper cutting mechanism from working.

[0042] Among them, the driving mechanism includes a driving lead screw 29 and a second servo motor 30. The specific structure of the driving mechanism is as follows: The second servo motor 30 is installed at the upper end of the elevated frame 12, the driving lead screw 29 is connected to the lower end of the elevated frame 12 and is connected to the output shaft of the second servo motor 30. The lifting guillotine 13 includes a lifting frame 31, and the lifting frame 31 is threadedly connected to the driving lead screw 29. The second servo motor 30 drives the driving lead screw 29 to rotate, so that the lifting guillotine 13 moves up and down, thereby cutting the cardboard that has moved below the lifting guillotine 13.

[0043] In addition, a limiting rod 27 is fixedly connected to the elevated frame 12, and the lifting frame 31 is slidably connected to the limiting rod 27. Through the above structure, it is ensured that the lifting frame 31 can always move vertically up and down and will not rotate due to the rotation of the driving lead screw 29.

[0044] The waste cutting mechanism includes a rotating wheel 19, a transmission rod 20 and a cutting knife 21. The specific structure of the waste cutting mechanism is as follows: A rotating shaft 23 is rotatably connected to the mounting frame, the rotating wheel 19 is fixedly connected to the rotating shaft 23, an eccentric shaft 25 is eccentrically connected to the rotating wheel 19, and the transmission rod 20 is hinged to the eccentric shaft 25. Thus, when the rotating wheel 19 rotates, the cutting knife 21 flips upward. The cutting knife 21 is fixedly connected to the lower end of the transmission rod 20. A first synchronous belt 24 is connected between the output shaft of the first servo motor 16 and the rotating shaft 23, and the first servo motor 16 drives the rotating shaft 23 to rotate through the first synchronous belt 24.

[0045] The transmission rod 20 includes a lower rod 33 and a hinged rod 34. One end of the hinged rod 34 is hinged left and right to the upper end of the lower rod 33, and the other end of the hinged rod 34 is hinged left and right to the eccentric shaft 25; A resilient plate 35 is fixedly connected to the mounting frame 14 below the rotating wheel 19, and a through hole 36 is formed in the resilient plate 35. The lower rod 33 slides up and down in the through hole 36. Through the above structure, the cutting knife 21 is limited, preventing the cutting knife 21 from rotating with the rotating wheel 19, ensuring that the cutting knife 21 can only move up and down, so that the cutting knife 21 can cut waste paper.

[0046] The working principle of the waste cutting mechanism is as follows: When the circular knife 15 cuts the front and back sides of the cardboard, long strip-shaped waste paper will be generated. Since the waste paper is connected to the cardboard during the cutting process, the waste paper cannot fall into the waste slot 17. The cutting knife 21 cuts the waste paper into small pieces, so that the waste paper can fall into the waste slot 17, which does not affect the operation table, and at the same time facilitates the operator to collect the waste paper after the slitting operation is completed.

[0047] In addition, a movable door 26 is hinged to the bottom of the waste paper slot 17, and a bolt (not shown in the figure) is provided on the movable door 26. After the slitting operation is completed, the operator can open the movable door 26 to take out the waste paper in the waste paper slot 17.

[0048] Moreover, on this basis, Embodiment 2 is proposed: the bottom of the waste paper slot 17 is an inclined slope, the movable door 26 is hinged to the lowest point of the bottom of the waste paper slot 17, an air extraction pump 32 is installed at the lower end of the operating table 11, and the air extraction port of the air extraction pump 32 is located at the highest point of the bottom of the waste paper slot 17.

[0049] The cut waste paper is sucked into the waste paper slot 17 by the air extraction pump 32 and accumulates at the movable door 26 along the inclination angle of the bottom of the waste paper slot 17, which further facilitates the operator to clean the waste in the waste paper slot 17. It should be noted here that when the operator opens the movable door 26 for cleaning, the air extraction pump 32 needs to be turned off to prevent the waste paper from being adsorbed by the air extraction pump 32 and unable to slide to the movable door 26.

[0050] At the same time, it should be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present invention.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. 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.
