Technical Field

[0001] The utility model relates to the technical field of hole-opening devices, in particular to a hole-opening device for packaging boxes with convenient positioning. Background Art

[0002] During the production and use of packaging boxes, it is often necessary to perform hole-opening operations on the packaging boxes for the convenience of installing accessories, ventilation, etc. Publication No.: CN220946894U discloses a hole-opening device for carton production, which includes a fixed frame, a moving mechanism, and a squeezing and hole-opening mechanism. The moving mechanism is installed on the top surface of the fixed frame, and the squeezing and hole-opening mechanism is installed at the upper end of the fixed frame. The squeezing and hole-opening mechanism includes a lifting unit, a fixing unit, and a cutting unit. The lifting unit is installed on the top surface of the fixed frame, the fixing unit is installed in the middle of the lifting unit, and the cutting unit is installed at the bottom end of the fixing unit. For this hole-opening device for carton production, by installing a squeezing and hole-opening mechanism, when opening holes in different cartons, the inserting rod can be taken out of the slot by pulling the squeezing plate to both sides. After completion, the annular punching cutter head can be removed, and then the corresponding-sized annular punching cutter head can be installed to open holes of different sizes and shapes, solving the problem that the original device can only open holes of a fixed size. However, during the use of the above technology, when the carton board is being opened, it does not have the function of fixing and limiting the carton board, so that the carton board may be accidentally offset during the hole-opening process, resulting in inaccurate positioning of the carton hole-opening, easy to cause the offset of the hole-opening position, and affecting the quality and use effect of the packaging carton hole-opening.

There are two groups of clamping plates 8, and the two groups of clamping plates 8 are symmetrically distributed on both sides of the middle of the surface of the workbench 1. Here, the cardboard can be fully clamped, avoiding the offset of the cardboard during the opening process, which is beneficial to improving the accuracy and precision of the cardboard opening. A chute 5 is opened on the surface of the first support frame 2. A limiting block 6 is fixedly connected to the surface of the driving block 7, and the limiting block 6 is slidably connected inside the chute 5. Here, it can play a role in guiding and limiting the movement of the clamping plate 8, so that it will not be deflected due to the rotation of the bidirectional lead screw 10. The anti-slip pad 9 is made of natural rubber. Here, it can increase the friction when the clamping plate 8 clamps the cardboard, making the clamping of the cardboard by the clamping plate 8 more firm. At the same time, it can also prevent the clamping plate 8 from scratching the cardboard. A second spring 26 is fixedly connected to the surface of the tool holder 13. A convex block 25 is slidably connected to the inside of the annular punching cutter head 14, and the convex block 25 is fixedly connected to the second spring 26. Here, it can prevent the cardboard waste cut off from getting stuck inside the annular punching cutter head 14, avoiding affecting the subsequent carton opening work.

[0026] Embodiment 2

[0027] Please refer to Figures 1-6, a collection box 15 is provided on the lower surface of the workbench 1. A T-shaped groove 18 is opened on the lower surface of the workbench 1. A T-shaped rod 16 is fixedly connected to the surface of the collection box 15. The T-shaped rod 16 is slidably connected inside the T-shaped groove 18. A discharge port 17 is opened on the surface of the workbench 1. The discharge port 17 is located directly above the collection box 15. Here, the waste generated during the hole-opening process can be collected, preventing the waste from falling on the workbench 1. At the same time, it is also convenient for subsequent centralized treatment of the waste, facilitating the recycling of the waste and avoiding waste of resources. A square block 20 is fixedly connected to the surface of the collection box 15. A slider 21 is slidably connected inside the square block 20. A limiting rod 22 and a pull rod 24 are fixedly connected to the surface of the slider 21. A first spring 23 is sleeved on the surface of the pull rod 24. A limiting hole 19 is opened on the lower surface of the workbench 1. The limiting rod 22 is inserted inside the limiting hole 19. Here, the collection box 15 slidably connected to the workbench 1 can be fixed, preventing it from moving due to the vibration of the workbench 1, so as not to affect the collection effect of the waste during the hole-opening process.

[0028] Working principle: During use, when it is necessary to punch holes in the cardboard of the packing box, first place the cardboard on the workbench 1 and make the position where the hole needs to be punched directly below the annular punching cutter head 14. Then, rotate the handle 11 on one side of the first support frame 2. The handle 11 drives the bidirectional lead screw 10 to rotate. While the bidirectional lead screw 10 rotates, it drives the two groups of driving blocks 7 and clamping plates 8 to move towards each other and clamp and limit the cardboard. At this time, the limiting block 6 on the driving block 7 slides in the chute 5 on the first support frame 2, and the anti-slip pad 9 on the clamping plate 8 is closely attached to the edge of the cardboard, realizing the clamping and positioning of the cardboard of the packing box, so that the cardboard will not shift during the hole punching process, which is beneficial to improving the accuracy and precision of cardboard hole punching, avoiding the deviation of the hole punching position. At the same time, the anti-slip pad 9 can also prevent the clamping plate 8 from scratching the cardboard. Then, start the hydraulic rod 4 on the second support frame 3. The output end of the hydraulic rod 4 pushes the fixed plate 12, the tool holder 13 and the annular punching cutter head 14 to move downward and punch holes in the cardboard. When the hole punching is completed, the cut cardboard will be stuck inside the annular punching cutter head 14. At this time, the second spring 26 will push the convex block 25 downward and push out the cardboard waste stuck inside the annular punching cutter head 14. The cut cardboard waste will fall into the chip collection box below the discharge port 17 through the discharge port 17, realizing the collection of waste generated during the hole punching process, preventing the waste from falling on the workbench 1, and at the same time facilitating the subsequent centralized treatment of the waste, facilitating the recycling of the waste, and avoiding waste of resources. When a certain amount of waste accumulates in the chip collection box, pull down the pull rod 24 on the square block 20. While the pull rod 24 moves downward, it drives the slider 21 and the limiting rod 22 to move downward and compress the first spring 23, and finally makes the limiting rod 22 disengage from the limiting hole 19. Then, hold the handle 11 on the collection box 15 and pull the collection box 15 outwards, so that the T-shaped rod 16 on the collection box 15 disengages from the T-shaped groove 18 on the workbench 1. Then, the waste in the collection box 15 can be centrally treated, realizing the collection of waste generated during the hole punching process, preventing the waste from falling on the workbench 1, and at the same time facilitating the subsequent centralized treatment of the waste, facilitating the recycling of the waste, and avoiding waste of resources.
