Description

Technical Field

[0001] This utility model relates to the field of cardboard production technology, and in particular to a cardboard punching device for cardboard production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of different types of paper are different, and the paper produced by different manufacturers also varies in color and texture. In daily life, if you need to punch holes in cardboard, you will need to use a cardboard punching device.

[0003] When applying for this utility model, a search revealed a Chinese patent that discloses a "cardboard punching device for cardboard production" with application number "202322147538.2". This patent uses a baffle to limit the position of the cardboard and prevent the punching position from shifting. However, if batch punching is required, this device has limitations and is only suitable for punching a small number of single holes. It does not meet the needs of multiple punching in production. Furthermore, the punching device lacks the function of cleaning the adsorbed paper pieces, and the operator has to clean them by hand, which can easily cause injury to the hands.

[0027] Reference Figure 1-5This utility model provides a cardboard punching device for cardboard production, comprising: a connecting plate 1 and a working chamber 23. Vertical plates 25 are fixedly connected to both ends of the connecting plate 1 to provide sliding space for the fixing member 2. First connecting blocks 16 are fixedly connected to the lower surfaces of the two vertical plates 25. A bearing plate 15 is fixedly connected between the two first connecting blocks 16 to provide a place for the punching knife 12. The punching knife 12 is slidably connected to the middle of the bearing plate 15 for punching holes in the cardboard. Sliding grooves 24 are provided on the inner sides of the two vertical plates 25. Second connecting blocks 18 are slidably connected to the inner walls of the two sliding grooves 24. A fixing member 2 is fixedly connected between the two second connecting blocks 18 to fix the cardboard and prevent the cardboard from shifting during punching. The fixing member 2 is hollow in the middle to facilitate touching and pressing the vertical rod 21 inside the punching knife 12. The lower surface of the fixing member 2 is in contact with the punching knife 12.

[0028] The punching knife 12 has a slide 22 running through its middle to provide a sliding space for the vertical rod 21. Two second springs 20 are fixedly connected at intervals on the upper surface of the punching knife 12, connecting the horizontal plate 19 and the punching knife 12 and acting as a buffer. The upper ends of the two second springs 20 are fixedly connected to the horizontal plate 19, and the lower surface of the horizontal plate 19 is fixedly connected to the vertical rod 21, which is used to clean the paper pieces adsorbed on the knife edge. The outside of the vertical rod 21 is slidably connected to the inner wall of the slide 22.

[0029] Both second connecting blocks 18 have threaded grooves 17 in the middle to provide a fixing place for bolts 5. Both vertical plates 25 have two fixing holes 4 that are spaced apart on one side. Bolts 5 pass through the fixing holes 4 and enter the threaded grooves 17.

[0030] The two threaded grooves 17 and the four fixing holes 4 are matched in diameter, and the inner walls of the two threaded grooves 17 are threaded with bolts 5.

[0031] Multiple limiting rods 6 are slidably connected at intervals in the middle of the bearing plate 15, which makes it easy for the bearing plate 15 to cut vertically down along the path of the limiting rods 6 with the punching knife 12. The lower surface of the multiple limiting rods 6 is fixedly connected to the pressure plate 13, which is used to press the cardboard and play a positioning role.

[0032] Multiple limit rods 6 are externally provided with first springs 10, which connect the bearing plate 15 and the pressure plate 13 and also serve as buffers. The upper surfaces of the multiple first springs 10 are fixedly connected to the lower surfaces of the bearing plate 15, and the lower surfaces of the multiple first springs 10 are fixedly connected to the upper surfaces of the pressure plate 13.

[0033] An electric rod 3 is fixedly connected to the upper surface of the working chamber 23, which pushes the drilling device downward. The output end of the electric rod 3 is fixedly connected to the upper surface of the connecting plate 1.

[0034] The bottom surface of the working chamber 23 is provided with a threaded chamber 11, which provides a place for the bidirectional threaded rod 14. The bidirectional threaded rod 14 is rotatably connected to the inner wall of the threaded chamber 11. The bidirectional threaded rod 14 drives two threaded blocks 9 to move relative to each other. The two threaded blocks 9 are externally threaded to the bidirectional threaded rod 14. The two threaded blocks 9 move relative to each other with two limiting plates 7. The upper surfaces of the two threaded blocks 9 are fixedly connected to the limiting plates 7 to limit the cardboard.

[0035] The bottom of the working chamber 23 is provided with a sliding groove to provide a sliding space for the limiting plate 7. The two limiting plates 7 are slidably connected to the inner wall of the sliding groove. A motor 8 is provided on one side of the working chamber 23 to drive the bidirectional threaded rod 14 to rotate. The output end of the motor 8 is fixedly connected to one end of the bidirectional threaded rod 14.

[0036] Working principle: When using, select the required number of punching blades 12. When installing the punching blades 12, slide them through the hollow of the first connecting block 16 into the hollow of the support plate 15, so that the upper ends of the punching blades 12 are mounted on both sides of the support plate 15. Move the fixing piece 2 from the slide groove 24 so that the lower surface of the fixing piece 2 is tightly against the upper surface of the punching blade 12. After they are in contact, use bolts 5 to pass through the fixing holes 4 and enter the threaded groove 17 for threaded fixation, achieving the effect of fixing the punching blades 12 with the fixing piece 2. Place the cardboard on the table of the working chamber 23, start the motor 8 to drive the bidirectional threaded rod 14 to rotate. The threaded block 9 on the 4 drives the two limiting plates 7 to move and fix the cardboard. The electric rod 3 is activated to push down the connecting plate 1, thereby driving the entire punching device downward. During the downward push, the pressure plate 13 first touches the cardboard and presses it to fix it, preventing the cardboard from shifting during punching. As it continues to push down, the bearing plate 15 carries the punching knife 12 and descends vertically along the path of the limiting rod 6 until the punching is completed. If a piece of paper is adsorbed inside the punching knife 12 after punching, the horizontal plate 19 is pressed down from the hollow part of the fixing part 2 to drive the vertical rod 21 downward to push the paper out from the punching opening, thereby completing the cleaning of the paper.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
