Description

Technical Field

[0001] This invention relates to the field of paper box processing, and more particularly to a recyclable paper box cutting device. Background Technology

[0002] A paper box cutting device is a specialized piece of equipment used to process flat paper into foldable paper box templates through cutting, creasing, and other processes. Since the paper box cutting device can only cut paper of the same size, it is necessary to process the paper size first before the paper box cutting and creasing operations can be carried out.

[0003] Paper is processed using a cutting blade on the surface of the conveyor belt. However, since the cutting blade moves up and down to cut the paper, and the bottom of the paper is the conveyor belt, and the conveyor belt is stretched for a long time, the cutting blade will come into contact with the surface of the conveyor belt when cutting the paper, which will affect the service life of the conveyor belt. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology. The present invention proposes a recyclable cardboard box cutting device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a recyclable cardboard box cutting device, comprising: a support frame and a conveyor belt disposed in the middle of the support frame; It also includes an upper frame set on the surface of the support, the surface of the upper frame is equipped with a circular knife, the surface of the conveyor belt is equipped with a central column, the surface of the central column is equipped with a flat frame, the central column changes the moving position of the conveyor belt so that the circular knife can only contact the flat frame.

[0006] Preferably, the surface of the shelf is provided with a vertical frame, and the surface of the vertical frame is provided with a horizontal frame, the vertical frame changing the vertical position of the horizontal frame.

[0007] Preferably, the surface of the transverse frame is provided with a flat frame, and the surface of the flat frame is provided with a motor, which is connected to the circular knife.

[0008] Preferably, the surface of the bracket is provided with an outer frame, and the surface of the flat frame is provided with a connecting rod, and the outer frame restricts the movement position of the flat frame.

[0009] Preferably, a long rod is connected to the surface of the connecting rod, and a push rod is connected to the surface of the long rod.

[0010] Preferably, the outer frame is inclined relative to the support.

[0011] Preferably, the circular blade is inclined relative to the conveyor belt, and the inclination angles of the circular blade and the outer frame are equal.

[0012] Preferably, a side column is provided on one side of the central column, and the central column and the side column guide the movement of the conveyor belt.

[0013] Compared with the prior art, the beneficial effects of the present invention include: by changing the moving position of the conveyor belt through the central column and side columns, the middle part of the conveyor belt can be located at a lower position, which facilitates the accommodation of the flat frame. At the same time, the push rod can drive the flat frame to move upward, thereby lifting the cardboard and allowing the circular knife to contact the soft flat frame inside, thereby avoiding cutting the conveyor belt.

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Example 1 According to one embodiment of the present invention, Figures 1-5As shown, a conveyor belt 2 is provided in the middle of the support 1. The conveyor belt 2 rotates on the surface of the support 1. An upper frame 3 is fixed at the upper end of the support 1. A longitudinal frame 4 is fixed on the surface of the upper frame 3. A transverse frame 5 is slidably connected to the surface of the longitudinal frame 4. A flat frame 8 is slidably connected to the surface of the transverse frame 5. A motor 6 is fixed on the surface of the flat frame 8. A circular knife 7 is driven to the surface of the motor 6. The longitudinal frame 4 drives the transverse frame 5 to move longitudinally. The transverse frame 5 drives the flat frame 8 to move horizontally. The motor 6 on the surface of the flat frame 8 drives the circular knife 7 to rotate, thereby cutting the paper.

[0022] The support 1 is rotatably connected to a central column 9 and a side column 10. The middle part of the conveyor belt 2 is disconnected from the central column 9. The central column 9 is located above the conveyor belt 2, and the side columns 10 are located on both sides of the central column 9, thereby restricting the movement of the conveyor belt 2. This allows the middle part of the conveyor belt 2 to move downward around the surfaces of the side columns 10 and the central column 9. Therefore, when the circular cutter 7 moves downward, it cannot contact the conveyor belt 2.

[0023] An outer frame 11 is fixed to the surface of the support 1. A connecting rod 14 is slidably connected inside the outer frame 11. The middle of the connecting rod 14 is fixedly connected to the flat frame 8. The flat frame 8 is located above the central column 9. The top of the flat frame 8 is flush with the surface of the conveyor belt 2. The cardboard moves normally on the surface of the flat frame 8. The push rod 13 pushes the long rod 12 to move. The long rod 12 moves and drives the connecting rod 14 to move. The connecting rod 14 moves inside the outer frame 11 and drives the flat frame 8 to move. The outer frame 11 is tilted relative to the support 1, so the flat frame 8 tilts upward. Since the longitudinal frame 4 is tilted relative to the upper frame 3, the angle at which the circular knife 7 moves downward is equal to the angle at which the flat frame 8 moves upward. After the circular knife 7 cuts the cardboard, the flat frame 8 is exposed.

[0024] In this embodiment, a long cardboard is placed on the surface of the conveyor belt 2. The conveyor belt 2 rotates, causing the long cardboard to move. The upper frame 3 is located at the upper end of the support 1 and does not affect the movement of the long cardboard. The middle part of the conveyor belt 2 moves along the central column 9 and the side column 10. The flat frame 8 is flush with the surface of the conveyor belt 2, so the long cardboard moves above the flat frame 8. When the long cardboard moves to a suitable length, the conveyor belt 2 stops rotating. The longitudinal frame 4 drives the transverse frame 5 to move downward. The transverse frame 5 moves downward, causing the flat frame 8 to move downward. The flat frame 8 moves downward, causing the circular knife 7 on the surface to move downward. At the same time, the push rod 13 pushes the long rod 12 to move. The long rod 12 drives the connecting rod 14 to move inside the outer frame 11, so the flat frame 8 moves upward at an angle. The flat frame 8 is located at the bottom of the cardboard. The upward movement of the flat frame 8 lifts the cardboard. The circular knife 7 cooperates with the flat frame 8 to cut the cardboard. The transverse frame 5 drives the flat frame 8 to move horizontally. The motor 6 drives the circular knife 7 to move horizontally, thereby completely cutting the cardboard. The cut cardboard moves along the conveyor belt.

[0025] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
