Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical packaging technology, and in particular to an inflation device and a blister packaging machine. Background Technology
[0002] A blister packaging machine is a machine that uses plastic film or sheet to form blister packs, and then seals the product between the blister pack and the base plate using methods such as heat sealing or adhesive bonding. Blister packaging machines generally include roller blister packaging machines, flat blister packaging machines, and plate roller blister packaging machines.
[0003] The working principle of a blister packaging machine is generally as follows: first, the forming film is heated and softened by a heating device, and then a blister is formed by vacuum negative pressure adsorption or compressed air blow molding. Then, the packaged item is filled into the blister using a filling device. Using the principle of heat sealing, the cover film coated with adhesive on one side is sealed onto the surface of the blister under appropriate temperature and pressure to form a blister and seal the packaged item inside the blister packaging.
[0004] Pharmaceuticals are commonly packaged using blister packs. To prevent oxidation, moisture absorption, or microbial growth, and thus ensure the stability and efficacy of the drugs, protective gases such as nitrogen are injected into the blister packs before sealing them with a covering film. Existing nitrogen filling devices suffer from low filling efficiency and poor uniformity when filling small blister packs.
[0005] Therefore, there is an urgent need for an inflation device and a blister packaging machine to solve the above problems. Utility Model Content

[0044] Figure 1A schematic diagram of the blister packaging machine provided in an embodiment of the present invention is shown; Figure 2 A partial structural schematic diagram of the inflation device provided in an embodiment of this utility model is shown. (Refer to...) Figure 1 and Figure 2 This embodiment provides an inflation device and a blister packaging machine. The blister packaging machine includes a blister forming device 10, a filling device 20, and a heat sealing device 30 arranged sequentially, and also includes the inflation device provided in this embodiment. The blister forming device 10 is configured for forming blister packs. The filling device 20 is configured for placing the packaged item into the blister pack; in this embodiment, the packaged item can be a pharmaceutical product. The heat sealing device 30 is configured to seal a covering film onto the surface of the blister pack to seal the packaged item within the blister pack. The inflation device is disposed between the filling device 20 and the heat sealing device 30 and is used to inflate the blister pack with protective gas. The blister forming device 10, the filling device 20, and the heat sealing device 30 provided in this embodiment are all prior art, and their structures and principles will not be described in detail here.
[0045] Specifically, the blister packaging machine also includes a transfer device 40. The blister forming device 10 is connected to the heat sealing device 30 via the transfer device 40. The transfer device 40 is configured to move the blister packs. An inflation cover 100 is positioned above the transfer device 40, allowing multiple blister packs on the transfer device 40 to sequentially pass through the inflation cover 100 and enter the heat sealing device 30. In this embodiment, the transfer device 40 can specifically be a conveying device or similar device from the prior art.
[0046] Figure 3 A schematic diagram of the inflatable cover and connecting mechanism provided in an embodiment of the present invention is shown; Figure 4 This is a top view showing the inflator head arranged on the inflator cover according to an embodiment of the present invention. (Refer to...) Figures 2-4 The inflation device provided in this embodiment includes an inflation cover 100, an air source 200, and a connecting mechanism 300. The inflation cover 100 can cover a blister pack containing the packaged item. The connecting mechanism 300 connects the inflation cover 100 and the air source 200, and includes multiple inflation heads 310. The multiple inflation heads 310 are spaced apart from each other and are all connected to the inflation cover 100. The air source 200 can provide a protective gas. In this embodiment, the protective gas can specifically be nitrogen. By providing multiple spaced-apart inflation heads 310 on the inflation cover 100, the uniformity of the protective gas filling into the inflation cover 100 can be improved, thereby improving the uniformity of the protective gas filling inside the blister pack.
[0047] Specifically, the connecting mechanism 300 also includes a flexible tube 320, through which the inflation head 310 is connected to the air source 200. The flexible tube 320 can be a silicone tube. Using the flexible tube 320 provides greater flexibility and does not affect or restrict the relative placement of the air source 200 and the inflation cover 100.
[0048] More specifically, the connecting mechanism 300 also includes an air source connector 330, which is connected to the flexible tube 320. The air source 200 is detachably connected to the air source connector 330 via a connecting pipe or the like. The air source connector 330 facilitates flexible disassembly and connection between the air source 200 and the inflatable cover 100.
[0049] Specifically, the inflation hood 100 is equipped with an anti-impact component 110, which is located on the air outlet path of the inflation head 310, between the inflation head 310 and the blister pack. The anti-impact component 110 prevents the protective gas from impacting the packaged item inside the blister pack when it enters the inflation hood 100 through the inflation head 310, eliminating the need for subsequent rearrangement of the packaged item and thus improving the efficiency and effectiveness of inflating the blister pack with protective gas.
[0050] Figure 5 A side view of an inflatable hood provided in an embodiment of the present invention is shown. (Refer to...) Figures 3-5 The inflation head 310 is connected to the top of the inflation cover 100. The shock absorber 110 has a plate-like structure, with one end connected to the inner top of the inflation cover 100. Along the extending direction of the shock absorber 110, the shock absorber 110 gradually moves away from the inner top of the inflation cover 100. The inclined arrangement of the shock absorber 110 guides the protective gas flowing out of the inflation head 310, allowing it to flow smoothly into the inflation cover 100.
[0051] Specifically, the plurality of inflation heads 310 are arranged at intervals along the extension direction of the shock absorber 110, and the shock absorber 110 corresponds to the plurality of inflation heads 310.
[0052] More specifically, such as Figure 2 and Figure 5As shown, multiple inflation heads 310 are arranged in two rows along the width direction of the inflation cover 100, with each row including multiple inflation heads 310 spaced apart along the length direction of the inflation cover 100. In this embodiment, four inflation heads 310 are specifically provided, arranged in a rectangular array. There are two shock absorbers 110, each corresponding to one of the two rows of inflation heads 310, and each extending away from the other. Through the arrangement of the shock absorbers 110, the protective gas flowing out of the inflation heads 310 can be guided to the inner wall of the inflation cover 100, where it undergoes secondary buffering, further reducing the flow rate of the protective gas in the inflation cover 100, thereby further preventing the protective gas from impacting the packaged object.
[0053] Continue to refer to Figures 1-5 The inflatable cover 100 is positioned upstream of the heat-sealing device 30 of the blister packaging machine. Abutment plate 120 is provided on one side of the inflatable cover 100, which abuts against the heat-sealing device 30. In this embodiment, the heat-sealing device 30 is provided with multiple guide rollers that are parallel to each other and spaced apart. These guide rollers are spaced apart in the vertical direction to guide and flatten the covering film. The abutment plate 120 is inclined relative to the side of the inflatable cover 100, matching the arrangement of the multiple guide rollers. The contact between the abutment plate 120 and the multiple guide rollers improves the stability of the inflatable cover 100.
[0054] Preferably, the inflatable cover 100 is a visible structure. In this embodiment, the inflatable cover 100 can be made of acrylic material. This design allows operators to easily observe the blister pack and packaged items within the inflatable cover 100, enabling timely detection of any abnormalities.
[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
