Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and more specifically, to a punching device for blister packaging boxes. Background Technology

[0002] Blister packaging boxes are plastic products produced using a blister forming process. They are mainly used for product packaging and protection, and their main uses include protection, separation, shock absorption, and lining. They are suitable for packaging a variety of products, such as electronics, IT products, industrial parts, toys, stationery, and food.

[0003] Currently, blister packaging boxes are frequently perforated during the production process. Perforation releases internal pressure and prevents expansion. For products requiring air circulation, such as food and beverages, perforation ensures airflow and prevents spoilage. However, most existing perforation devices use cylinders to control the perforation of blister packaging boxes. Since blister packaging boxes typically have a certain degree of flexibility, direct downward pressure from the perforation needle results in significant resistance and poor forming effect. Some perforation devices use a cylinder combined with a motor to control the perforation needle, with the cylinder controlling the needle's rise and fall and the motor controlling its rotation to drill holes in the blister packaging box. While this method ensures perforation results, it is costly. Therefore, this invention proposes a perforation device for blister packaging boxes. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a punching device for blister packaging boxes. This device aims to solve the problem that most existing punching devices use a cylinder to control the punching action when punching blister packaging boxes. Since blister packaging boxes typically have a certain degree of toughness, directly pressing the punching needle downwards results in significant resistance and poor forming effect. Some punching devices use a cylinder combined with a motor to control the punching needle; the cylinder controls the raising and lowering of the punching needle, and the motor controls the rotation of the punching needle to drill holes in the blister packaging box. While this ensures the punching effect, it also results in high operating costs.

[0028] Example:

[0029] Please see Figure 1-3 A punching device for blister packaging boxes includes a base plate 1, a gantry frame 2 fixedly connected to the top of the base plate 1, two side baffles 3 slidably connected to the top of the base plate 1, the two side baffles 3 being symmetrically distributed on the inner side of the gantry frame 2, a lifting cylinder 4 fixedly connected to the top of the gantry frame 2, the output end of the lifting cylinder 4 movably extending through the inner side of the gantry frame 2, a lifting plate 5 fixedly connected to the output end of the lifting cylinder 4, and two sliding rods 6 slidably inserted into the lifting plate 5, the bottom ends of the two sliding rods 6 being fixedly connected to the lifting plate 5. A pressure plate 7 is fixedly connected and located below the lifting plate 5. Springs 8 are fitted on the outer surfaces of two sliding rods 6 and are located between the pressure plate 7 and the lifting plate 5. A drill head 9 is rotatably connected to the bottom end of the lifting plate 5 and moves through the pressure plate 7. A material discharge port 10 is opened on the bottom plate 1 and corresponds to the drill head 9. A linkage mechanism is provided between the lifting plate 5 and the pressure plate 7. The linkage mechanism is used to control the rotation of the drill head 9 to realize the drilling of the blister packaging box.

[0030] In this embodiment, the blister packaging box is placed on the base plate 1 and transported. The blister packaging box moves through the two side baffles 3 and passes under the drill head 9. The lifting cylinder 4 controls the lifting plate 5 to press down, so that the pressure plate 7 contacts the blister packaging box. The lifting plate 5 continues to press down and compresses the two springs 8. Under the elastic action of the two springs 8, the pressure plate 7 elastically presses and positions the blister packaging box. At the same time, the lifting plate 5 drives the drill head 9 to penetrate the pressure plate 7 and drill a hole in the blister packaging box. The linkage mechanism makes the drill head 9 rotate during the process of penetrating the pressure plate 7, so that the drill head 9 rotates and presses down through the discharge port 10. The waste material generated by drilling falls to the lower side of the base plate 1 through the discharge port 10, thereby completing the entire drilling process.

[0031] Specifically, the linkage mechanism includes a gear 111, two racks 112, and two connecting rods 113. The gear 111 is rotatably connected to the top of the pressure plate 7, and the drill bit 9 slides through the gear 111. The two racks 112 are slidably connected to the top of the pressure plate 7, and the two racks 112 are staggered and mesh with the gear 111. The two connecting rods 113 are respectively hinged between the lifting plate 5 and the two racks 112 through hinge shafts.

[0032] In this embodiment, after the lifting plate 5 presses down to make the pressure plate 7 contact the blister packaging box, the lifting plate 5 continues to press down to shorten the distance with the pressure plate 7 and make the drill head 9 penetrate the pressure plate 7 downward. The lifting plate 5 drives the two racks 112 to rotate the gear 111 through the two connecting rods 113. The gear 111 causes the drill head 9 to rotate when it presses down to drill, thereby improving the drilling effect.

[0033] Specifically, a protrusion 12 is fixedly connected to the inner circumference of the gear 111, and a groove 13 is provided on the circumference surface of the drill head 9, with the protrusion 12 slidably connected in the groove 13.

[0034] In this embodiment, when the lifting plate 5 drives the drilling head 9 to press down and make a hole in the blister packaging box, the drilling head 9 slides in the gear 111 through the slide groove 13 and the protrusion 12. When the gear 111 rotates, the downward pressure of the drilling head 9 will rotate through the protrusion 12 and the slide groove 13, thus drilling a hole in the blister packaging box.

[0035] Specifically, the bottom ends of the two racks 112 are fixedly connected to the slide bars 14, and the top of the pressure plate 7 has two sliding openings 15, with the two slide bars 14 slidably connected to the two sliding openings 15 respectively.

[0036] In this embodiment, the two racks 112 are slidably connected to the pressure plate 7 via two slide bars 14 and two slide openings 15. The two slide bars 14 and two slide openings 15 keep the sliding of the two racks 112 stable.

[0037] Specifically, the top of the lifting plate 5 is fixedly connected to the insertion rod assembly 16, and the top of the insertion rod assembly 16 extends through to the upper side of the gantry frame 2.

[0038] In this embodiment, the insert rod assembly 16 is used to assist the lifting plate 5 in lifting and lowering, so that the lifting plate 5 remains stable during lifting and lowering.

[0039] Specifically, both ends of the gantry frame 2 are threaded with threaded rods 17, and the ends of the two threaded rods 17 that are close to each other are rotatably connected to the ends of the two side baffles 3 that are far apart.

[0040] In this embodiment, the distance between the two side baffles 3 can be adjusted by the two threaded rods 17, so that the two side baffles 3 can adapt to the conveying of blister packaging boxes of different sizes.

[0041] Specifically, a set of sliders 18 are fixedly connected to the bottom of each of the two side baffles 3, and two sets of slides 19 are opened at the top of the base plate 1, with the two sets of sliders 18 slidably connected in the two sets of slides 19 respectively.

[0042] In this embodiment, when the two side baffles 3 move to adjust the distance, they will cause the two sets of sliders 18 to slide within the two sets of slide rails 19. The two sets of sliders 18 and the two sets of slide rails 19 are used to ensure the stability of the adjustment distance of the two side baffles 3.

[0043] Specifically, a pivot opening 20 is provided on the base plate 1, and a roller assembly 21 is rotatably connected inside the pivot opening 20.

[0044] In this embodiment, when the blister packaging box is conveyed on the upper end of the base plate 1, it will come into contact with the roller assembly 21 in the turnout 20. The roller assembly 21 makes the conveying of the blister packaging box on the base plate 1 smoother.

[0045] Working principle: When drilling holes in a blister pack, the blister pack is first placed on the base plate 1 and conveyed. The blister pack moves through the two side baffles 3 and passes under the drill head 9. The lifting cylinder 4 controls the lifting plate 5 to press down, so that the pressure plate 7 contacts the blister pack. The lifting plate 5 continues to press down, compressing the two springs 8. Under the elastic action of the two springs 8, the pressure plate 7 elastically presses and positions the blister pack. At the same time, the lifting plate 5 drives the drill head 9 to penetrate the pressure plate 7 and press down, shortening the distance between the lifting plate 5 and the pressure plate 7. The drill head 9 penetrates the pressure plate 7 downwards. The lifting plate 5 drives the gear 111 to rotate via two connecting rods 113 and two racks 112. The gear 111 causes the drill head 9 to rotate as it presses down to drill. The drill head 9 rotates and presses down through the material drop port 10. The waste material generated during drilling falls through the material drop port 10 to the lower side of the base plate 1, thus completing the entire drilling process. After the blister packaging box is drilled, the lifting cylinder 4 controls the lifting plate 5 to reset. Other components will also reset, which facilitates the continuous drilling of subsequent blister packaging boxes.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
