Technical Field

[0001] This utility model relates to the field of packaging processing equipment technology, specifically to a hole-opening device for processing blister packs. Background Technology

[0002] Blister boxes are a common type of packaging container, widely used in many industries such as food, electronics, and medical devices. During the processing of blister boxes, in order to meet the needs of ventilation, assembly, or labeling, it is often necessary to make holes in the blister boxes. A special hole-making device is required to make holes in the blister boxes.

[0003] Existing blister box processing hole-opening equipment includes die stamping hole opening, laser hole opening, and manual hole opening. Different hole opening methods are required depending on the batch and specifications of blister box production to achieve the desired hole opening effect. Existing die stamping hole opening uses a preset upper die to press and punch the blister box placed on the lower die to open the hole. The blister box is prone to displacement during transportation, resulting in insufficient hole position accuracy, affecting product quality. Moreover, the waste generated during hole opening is inconvenient to collect. The scattered waste not only pollutes the processing environment but also requires additional manpower for cleaning, reducing processing efficiency. Therefore, we need to propose a hole-opening device for packaging blister box processing. Utility Model Content

[0004] The purpose of this invention is to provide a hole-opening device for processing blister packs. An uncut blister pack is conveyed to the top of the lower mold via a conveyor belt. A guide rail on the top of the lower mold prevents the blister pack from shifting during transport and hole opening. The upper mold, driven by a mechanism, precisely engages the punch and the opening slot, achieving rapid hole opening and improving product yield. A material discharge chute on the top of the collection box corresponds to the punch position, allowing waste generated during hole opening to fall directly into the blister pack, achieving centralized waste collection and improving the efficiency of the hole-opening device. This addresses the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole-opening device for processing blister packs, comprising a conveying assembly, the conveying assembly including two sets of conveyor belts for conveying blister packs, a support assembly between the two sets of conveyor belts, and a hole-opening assembly mounted on the top of the support assembly; the support assembly including a collection box for support, the top of the collection box having a material drop groove; the hole-opening assembly including a lower mold bolted to the top of the collection box, the lower mold having several sets of hole-opening grooves through the lower middle part of the top, and several sets of guide rails fixedly mounted on the top of the lower mold; when uncut blister packs are conveyed, the blister packs slide along the several sets of guide rails through the grooves; an upper mold is mounted above the lower mold via a drive mechanism, and several sets of punches adapted to the hole-opening grooves are bolted to the bottom of the upper mold.

[0014] 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.

[0015] Please see Figures 1-4 This utility model provides a hole-opening device for processing blister packs, including a conveying assembly 1. The conveying assembly 1 includes two sets of conveyor belts 11 for conveying blister packs. A support assembly 2 is arranged between the two sets of conveyor belts 11. A hole-opening assembly 3 is installed on the top of the support assembly 2. The support assembly 2 includes a collection box 21 for support. A material drop groove 22 is opened on the top of the collection box 21. The hole-opening assembly 3 includes a lower mold 31 bolted to the top of the collection box 21. Several sets of hole-opening grooves 33 are opened through the lower middle part of the top of the lower mold 31. Several sets of guide rails 32 are fixedly installed on the top of the lower mold 31. When uncut blister packs are conveyed, several sets of blister packs slide along several sets of guide rails 32 through the grooves. An upper mold 37 is installed above the lower mold 31 through a drive mechanism. Several sets of punches 38 adapted to the hole-opening grooves 33 are bolted to the bottom of the upper mold 37.

[0016] In use, the conveyor belt 11 transports the uncut blister pack to the top of the lower mold 31. The guide rail 32 on the top of the lower mold 31 prevents the blister pack from shifting, effectively preventing it from shifting during transport and opening. The upper mold 37, driven by the drive mechanism, drives the punch 38 to precisely engage with the opening slot 33, achieving fast opening and improving product qualification rate. The material drop chute 22 on the top of the collection box 21 corresponds to the position of the punch 38. Waste generated during opening can fall directly into the drawer box 24 through the material drop chute 22, achieving centralized collection of waste and improving the efficiency of the opening equipment. It is worth noting that the distance the conveyor belt 11 moves the blister pack is fed back by a displacement sensor (not shown in the figure), ensuring that the blister pack can be accurately transported to the opening position, improving the opening accuracy.

[0017] Four sets of sliding rods 34 are fixedly installed on the top of the lower mold 31. A top plate 35 is fixedly installed on the top of the four sets of sliding rods 34. A pneumatic push rod 36 is bolted to the bottom of the top plate 35. The top of the upper mold 37 is bolted to the output end of the pneumatic push rod 36. When the blister box moves to the opening position, the pneumatic push rod 36 is extended to drive the upper mold 37 to move downward. The punch 38 descends with the upper mold 37 and inserts into the opening slot 33 to complete the opening of the blister box. Then the pneumatic push rod 36 drives the upper mold 37 to reset, thereby achieving the effect of rapid opening.

[0018] The four corners of the upper mold 37 are slidably fitted onto the outer arc surface of a set of slide rods 34. The slide rods 34 not only provide guidance for the lifting and lowering of the upper mold 37, but also enhance the stability of the upper mold 37's operation and improve the stamping alignment accuracy between the upper and lower molds. A set of limiting plates 39 are fixedly fitted onto the outer arc surface of the four sets of slide rods 34 located between the upper mold 37 and the lower mold 31. When the upper mold 37 completes its downward stamping, the four sets of limiting plates 39 lock the upper mold 37's downward movement, preventing the lower mold 31 from driving the punch 38 to excessively stamp and damage the lower mold 31 or the blister box.

[0019] A slot 23 is provided on one side of the collection box 21. A set of draw boxes 24 are movably inserted inside the slot 23. The draw boxes 24 are located directly below the discharge chute 22. Waste generated by the opening falls into the draw boxes 24 through the discharge chute 22. When the draw boxes 24 are full, they can be directly pulled out from the slot 23 for cleaning, which is convenient.

[0020] Four sets of support rods 25 are fixedly installed at the bottom of the collection box 21. Each of the four sets of support rods 25 is bolted to an adjustable base 26. The four sets of support rods 25 are located at the four corners of the collection box 21, providing stable support for the collection box 21. Each of the four sets of support rods 25 is bolted to an adjustable base 26. The base 26 adopts a threaded adjustment structure. By rotating the base 26, the height of the support rods 25 can be adjusted, thereby adjusting the height of the entire device to adapt to different usage requirements and production line heights.

[0021] Each of the two sets of conveyor belts 11 has a set of support frames 12 fixedly installed on both sides of the top. Each of the four sets of support frames 12 has a set of baffles 13 fixedly installed on one side to limit the conveying of the blister box. The baffles 13 are parallel to the conveying direction of the conveyor belts 11 and can limit the blister box from both sides, further improving the stability and positioning accuracy of the blister box during the conveying process.

[0022] In practical use: Before use, adjust the height of the support rod 25 by rotating the base 26 according to the processing requirements and the height of the production line to make the equipment at a suitable working height; at the same time, according to the specifications of the blister box, replace the corresponding lower mold 31 and upper mold 37 to ensure that the guide rail 32 can be matched with the groove of the blister box and the punch 38 and the opening slot 33 are precisely aligned. During operation, the blister pack to be perforated is placed on two sets of conveyor belts 11. One set of conveyor belts 11 transports the blister pack towards the perforation assembly 3. Baffles 13 on both sides of the conveyor belts 11 limit the movement of the blister pack from both sides. The guide rail 32 at the top of the lower mold 31 is inserted into the groove of the blister pack, achieving precise positioning and guidance. When the blister pack is transported directly below the punch 38, the conveyor belt 11 stops. The pneumatic actuator 36 is activated, pushing the upper mold 37 downwards along the slide bar 34. The punch 38 at the bottom of the upper mold 37 punches and perforates the blister pack. Waste material generated during punching is disposed of through... The opening slot 33 on the lower mold 31 falls into the material drop slot 22 on the top of the collection box 21, and finally enters the inside of the drawer box 24. After the punch 38 completes the opening, the air push rod 36 drives the upper mold 37 to reset upward; the conveyor belt 11 starts again and continues to transport the blister box to the processing position. After the opening is completed, the blister box is pushed by the blister box behind to another set of conveyor belts 11 to be transferred to the next process, realizing continuous processing. When the waste material inside the drawer box 24 is full, it can be directly pulled out from the drawer slot 23 of the collection box 21, cleaned, and then inserted back into the drawer slot 23 to continue waste collection.

[0023] 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.
