Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing, and in particular to a cardboard shell perforation device for cardboard box production. Background Technology

[0002] Cardboard boxes are one of the most widely used packaging products, usually made of cardboard or paper, and include parts such as the bottom, sides, and lid. Cardboard box perforation refers to creating holes in the cardboard box to meet needs such as ventilation, display, and handling.

[0003] For example, the paper perforation device for carton production disclosed in the utility model with authorization announcement number CN219883393U has a negative pressure fan that sucks away the paper scraps generated by the perforator through the sealing plate. As the perforator goes deeper into the carton, the sealing plate will stay close to the outer wall of the carton due to the foldable characteristics of the corrugated tube, so that the sealing plate can always absorb paper scraps on the outer wall of the carton.

[0004] The existing technology still has the following problems when used:

[0005] When perforating a cardboard box, pressing the cutter directly onto the surface will cause the box to dent. Since cardboard boxes do not have the property of springing back, dents that cannot spring back will affect the appearance of the cardboard box. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a cardboard perforation device for cardboard box production, which can solve the following technical problems: when perforating a cardboard box, the cutter presses directly down on the surface of the cardboard box, which will cause the cardboard box to be dented. Since the cardboard box does not have the characteristic of springing back, the dent that cannot spring back will affect the appearance of the cardboard box.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cardboard perforation device for carton production, comprising a side plate fixed to the side of a workbench, a support plate fixed to one side of the side plate, a movable groove formed on the top surface of the support plate, a square block disposed in the movable groove, the square block being able to move laterally inside the movable groove, two mounting circular grooves formed on the top surface of the square block, a guide rod passing through the inside of the mounting circular groove, a pressure plate fixed to the top of the guide rod, a spring sleeved on the outside of the guide rod located below the pressure plate, and a base plate fixed to the bottom of the guide rod located below the square block, with a circular knife and a needle fixed to the bottom of the two base plates respectively.

[0008] As a preferred embodiment of this utility model, a top plate is fixed to the top surface of the side plate, and a perforated cylinder is fixed to the bottom end of the top plate.

[0009] As a preferred embodiment of this utility model, a pushing cylinder is fixed at the top edge of the support plate, and the pushing cylinder is connected to the square block by a connecting block.

[0010] As a preferred embodiment of this utility model, the width of the movable groove is the same as the width of the square block, and limit strips are fixed on both sides of the square block.

[0011] As a preferred embodiment of this utility model, two downward pressing cylinders are fixed to the front side of the side plate, and a U-shaped pressure plate is fixed to the telescopic end of the downward pressing cylinder.

[0012] As a preferred embodiment of this utility model, an adjusting cylinder is fixed at the edge of the workbench, a push plate is fixed at the telescopic end of the adjusting cylinder, and a paper drop hole is provided on the top surface of the workbench.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] 1. By designing a base plate that is connected to the pressure plate via a guide rod, the cardboard box can be perforated when the base plate moves down. The cardboard box is first perforated with needles, and then the perforated circular paper is cut off with a circular knife. This reduces the contact area of ​​the cardboard box during perforation. After perforating the cardboard box with multiple needles, the circular knife can perforate the cardboard box more easily.

[0015] 2. By designing a movable square block, the circular knife and needle can be switched positions. The cardboard box is perforated by the downward pressure of the perforating cylinder. A U-shaped pressure plate installed below the downward pressure cylinder can press the cardboard box tightly to prevent displacement during perforation. Attached Figure Description

[0023] Example

[0024] Please refer to Figures 1-5 As shown, this utility model provides a cardboard perforation device for carton production, including a workbench 1. A side plate 6 is fixed on the top surface of the workbench 1. A pressing cylinder 5 is symmetrically fixed at the front end of the side plate 6. A U-shaped pressure plate 4 is fixed below the pressing cylinder 5. The U-shaped pressure plate 4 can fix the cardboard to be perforated. An adjusting cylinder 2 is fixed at the edge of the top surface of the workbench 1. A push plate 3 is fixed at the telescopic end of the adjusting cylinder 2. The position of the cardboard can be pushed by adjusting the cylinder 2 to change the perforation position.

[0025] like Figures 1-5As shown, a top plate 7 is fixed to the top of the side plate 6, and a perforated cylinder 8 is fixed to the bottom of the top plate 7. The telescopic end of the perforated cylinder 8 faces downward, and a paper drop hole 10 is provided on the top surface of the workbench 1. The paper drop hole 10 is located directly below the perforated cylinder 8. A support plate 9 is fixed to the front end of the side plate 6. A moving groove 12 is provided at the center of the top surface of the support plate 9. The moving groove 12 is located directly below the perforated cylinder 8. A square block 16 is placed inside the moving groove 12. The width of the moving groove 12 is the same as the width of the square block 16. Limit strips 11 are fixed to the front and rear sides of the square block 16. A pushing cylinder 15 is fixed to the edge of the top surface of the support plate 9. The pushing cylinder 15 and the square block 16 are connected by a connection. The block 14 is connected. The top surface of the square block 16 has two mounting grooves 17. A guide rod 19 is placed inside the mounting groove 17. A pressure plate 13 is fixed on the top surface of the guide rod 19. A spring 18 located below the pressure plate 13 is sleeved on the inside of the guide rod 19. The guide rod 19 passes through the square block 16 and is fixedly connected to the base plate 20. The bottom surfaces of the two base plates 20 are respectively fixed with a needle 22 and a circular knife 21. There are multiple needles 22, which are distributed in a circle. When the pushing cylinder 15 is in the natural state, the needle 22 is located directly below the perforating cylinder 8. When the pushing cylinder 15 pushes the square block 16 to the other end of the moving groove 12, the circular knife 21 is located directly below the perforating cylinder 8.

[0026] Specific working principle:

[0027] When perforation of the cardboard is required, the side plates 6 of the cardboard are brought together, and the position of the cardboard is adjusted by adjusting the cylinder 2, i.e., adjusting the punching position. The cardboard is then pressed tightly by the U-shaped pressure plate 4. The perforation cylinder 8 is activated, extending downward and pressing down on the pressure plate 13, causing the needle 22 below the pressure plate 13 to pierce the cardboard, creating a circle of needle holes on the cardboard. The perforation cylinder 8 retracts, and the spring 18 pushes the pressure plate 13 upward, resetting the needle 22. Then, the push cylinder 15 is activated, pushing the square block 16 to the other end of the moving groove 12. At this time, the circular knife 21 is located directly below the perforation cylinder 8. The perforation cylinder 8 is activated, pushing the circular knife 21 downward to cut the circular cardboard inside the needle hole, thereby reducing the contact area between the circular knife 21 and the cardboard and reducing the connection strength between the circular paper to be punched and the cardboard, thus preventing the cardboard from denting.
