Description

Technical Field

[0001] This utility model relates to the field of cardboard box opening technology, specifically a high-efficiency opening device for heavy-duty cardboard box production. Background Technology

[0002] In the logistics and packaging industry, heavy-duty cardboard boxes are widely used to transport various heavy items. To facilitate handling, it is essential to have carrying handles on the boxes. These handles not only significantly improve handling convenience but also prevent damage caused by directly handling the corners of the boxes.

[0003] According to a search, Chinese patent document, publication number CN219789422U, discloses a high-efficiency perforation device for cardboard box production. The cardboard to be perforated is placed on a positioning ring, and then the handle is pulled upwards, causing the extension rod to drive the connecting rod to rotate around a first steering shaft. This causes one end of the connecting rod to move downwards, pushing the connecting piece downwards. The connecting piece pushes the pressure plate downwards, causing the pressure plate to rotate around a rotating shaft. As the pressure plate moves downwards, it pushes the mounting block, connecting piece, and blade downwards. The blade contacts the cardboard and continues to press downwards, embedding itself into the positioning ring to cut and perforate the cardboard.

[0004] However, in actual use, when the blade contacts the cardboard and cuts a hole, cardboard waste gets stuck inside the blade, making it inconvenient to clean up the waste. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 A high-efficiency perforation device for heavy-duty carton production includes a base 1. A vertical rod 2 is bolted to the top surface of the base 1. A lower connecting arm 3 is fixedly connected to the outer surface of the vertical rod 2, and an upper connecting arm 4 is bolted to the top of the vertical rod 2. A rotating shaft 5 is rotatably connected inside the upper connecting arm 4. Square rods 6 are fixedly connected to both ends of the rotating shaft 5. An eccentric wheel 7 is inserted into the outer surface of the square rod 6, and a connecting plate 8 is bolted to one end of the square rod 6. A handle 9 is fixedly connected to the inner side of the connecting plate 8. A guide rod 10 is inserted inside the upper connecting arm 4, and a spring 11 is sleeved on the outer surface of the guide rod 10. An upper pressure plate 12 is fixedly connected to the bottom end of the guide rod 10. A ring cutter 13 is embedded in the lower surface of the upper pressure plate 12, and a material ejector rod 14 is inserted inside the upper pressure plate 12. A limit plate 15 is installed at the top of the guide rod 10, and a lower pad 16 is bolted to the front end of the lower connecting arm 3.

[0024] Specifically, a straight slot 17 is provided through the upper surface of the lower connecting arm 3. A screw 18 is slidably connected inside the straight slot 17. An L-shaped baffle 19 is fixedly connected to the top of the screw 18. A knob 20 is threadedly connected to the outer surface of the screw 18. A crossbar 21 is slidably connected inside the lower connecting arm 3. A baffle 22 is fixedly connected to one end of the crossbar 21. A knob 23 is threadedly connected to the lower surface of the lower connecting arm 3.

[0025] The advantage is that by loosening knob 120, the L-shaped baffle 19 no longer adheres to the upper surface of the lower connecting arm 3. This allows the L-shaped baffle 19 to be moved to adjust its position. After tightening knob 120 again, the L-shaped baffle 19 can be fixed. By loosening knob 23, it no longer abuts against the outer surface of the crossbar 21. Then, the crossbar 21 can be moved to adjust the position of the baffle 22. After adjusting the position of the baffle 22, tighten knob 23 again to fix the position of the baffle 22. When punching holes in the cardboard, the front end of the cardboard is placed against the outer surface of the L-shaped baffle 19, and the side end of the cardboard is placed against the outer surface of the baffle 22. This allows the punching position to be positioned.

[0026] Specifically, the top of the spring 11 abuts against the limiting piece 15, and the bottom of the spring 11 abuts against the upper connecting arm 4. The eccentric wheel 7 is eccentrically connected to the square rod 6. The outer circumferential surface of the eccentric wheel 7 contacts the upper pressure plate 12. The top of the ejector rod 14 is threadedly connected to the inside of the upper connecting arm 4. There are two connecting plates 8, and a handle 9 is fixedly connected between the two connecting plates 8.

[0027] The advantage is that by pulling the handle 9, the two connecting plates 8 are driven, the connecting plates 8 drive the square rod 6, and the square rod 6 drives the eccentric wheel 7 to rotate around the rotating shaft 5. When the eccentric wheel 7 rotates, it can drive the upper pressure plate 12 to move downward. The upper pressure plate 12 drives the ring cutter 13 to move downward. When the ring cutter 13 contacts the cardboard, it can punch holes in the cardboard in conjunction with the lower pad 16. When the handle 9 is released, the two springs 11 drive the limiting plate 15 to move upward. The limiting plate 15 drives the guide rod 10, and the guide rod 10 drives the upper pressure plate 12 to reset. In this way, the ejector rod 14 will push the waste material in the ring cutter 13, thus removing the waste material from the ring cutter 13.

[0028] In use, firstly, loosen knob 20, move the L-shaped baffle 19 to the appropriate position, and then tighten knob 20 again to fix the position of the L-shaped baffle 19; then, loosen knob 23, move the crossbar 21 to drive the baffle 22 to the required position, and then tighten knob 23 to fix the baffle 22; next, place the front end of the cardboard against the outer surface of the L-shaped baffle 19 and the side end against the outer surface of the baffle 22 to complete the positioning of the punching position; finally, pull handle 9 to drive the connecting plate 8 and the square rod 6 to make the eccentric wheel 7 rotate around the rotating shaft 5. The eccentric wheel 7 drives the upper pressure plate 12 to move downward, which in turn drives the ring cutter 13 downward, cooperating with the lower pad 16 to punch holes in the cardboard; when handle 9 is released, the two springs 11 drive the limiting plate 15 to move upward, and drive the upper pressure plate 12 to reset through the guide rod 10. The ejector rod 14 pushes out and removes the waste material in the ring cutter 13.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
