Description

Technical Field

[0001] This utility model relates to the field of mechanical packaging technology, and in particular to an inflation auxiliary device, an inflation device, and a blister packaging machine. Background Technology

[0002] Blister packaging machines are specialized sealing packaging equipment for products such as pharmaceuticals, food, and electronic components. By forming blister cavities, they achieve triple high-barrier protection for the contents, including moisture prevention, light protection, and oxidation resistance. Aluminum-aluminum blister packaging machines are one type of such machine. The process involves quantitatively dispensing the product into "bubble openings" (concave cavities) made of pressed aluminum foil, then sealing the bubble openings with another layer of aluminum foil to form independent sealed product units. Before sealing the bubble openings with another layer of aluminum foil, nitrogen gas needs to be injected into the bubble openings to protect the product. The nitrogen concentration inside the bubble openings must reach over 98% to prevent quality risks caused by oxygen concentration issues and to avoid reducing production efficiency.

[0003] Existing aluminum blister packaging machines typically have several openings on the inflatable base plate for nitrogen delivery. However, the opening positions do not correspond to the blister positions, meaning the inflation process can only align some openings with some blister areas. This results in nitrogen being inflated in non-blister areas as well, leading to nitrogen loss and low nitrogen utilization. Investigations have revealed that the nitrogen concentration inside the blister is only 95%, lower than the required concentration, which is detrimental to protecting the product inside the blister, creating quality risks and reducing production efficiency. Therefore, there is an urgent need for an inflatable auxiliary device for blister packaging machines to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an inflation auxiliary device, an inflation device and an inflation machine for blister packaging machines, so as to solve the problem of low nitrogen utilization rate caused by nitrogen loss, improve the nitrogen concentration in the blister packs and improve production efficiency.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides an inflation auxiliary device for a blister packaging machine, including an inflation tray and an inflation mechanism. The inflatable base plate is fixedly connected to the bottom end of the inflatable support plate. The inflatable support plate has a cavity inside, and the inflatable base plate has several slots. The top of the cavity is connected to a nitrogen source, and the bottom of the cavity is connected to each of the slots. Nitrogen can inflate the bubble eyes after passing through the cavity and the slots. The direction of travel of the bubble eyes is taken as the first direction, and the direction perpendicular to the direction of travel of the bubble eyes on the horizontal plane is taken as the second direction. The size of the slots in the second direction is the same as the size of the bubble eyes in the second direction. The spacing between the slots in the first direction and the bubble eyes in the first direction is the same, and the spacing between the slots in the second direction and the bubble eyes in the second direction is the same.

[0006] In one embodiment, the inflatable tray has a tablet reset surface at one end near the starting position of the eyeball delivery, and the distance of the tablet reset surface from the starting position of the eyeball delivery gradually decreases from bottom to top.

[0007] In one embodiment, the tablet's reset surface is a plane.

[0008] In one embodiment, a plurality of guide grooves are provided in the cavity, the guide grooves connect the cavity and the slot, and the extension direction of the guide grooves is parallel to the tablet reset surface.

[0009] In one embodiment, a gas filter is further included, the inlet of which is connected to the nitrogen source, the gas filter is used to filter the nitrogen, and the outlet of which is connected to the cavity.

[0010] In one embodiment, the system further includes an intake pressure reducing valve, the intake port of which is connected to the outlet of the gas filter, and the outlet of which is connected to the cavity. The intake pressure reducing valve is used to adjust the pressure of the nitrogen gas.

[0014] This utility model also discloses a blister packaging machine, including a blister packaging machine body and the above-mentioned blister packaging machine inflation device, wherein the blister packaging machine body is used to seal and package products.

[0015] The present invention achieves the following technical advantages over the prior art: This embodiment provides an inflation auxiliary device for a blister packaging machine. During use, the inflation tray is connected to the inflation base plate for conveying nitrogen. With the blister travel direction as the first direction, the spacing between the slots in this direction matches the spacing between the blister cells in the same direction. Similarly, the spacing between the slots in the second direction matches the spacing between the blister cells in the same direction.

[0018] 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.

[0019] The purpose of this invention is to provide an inflation auxiliary device, an inflation device, and a blister packaging machine to solve the problem of low nitrogen utilization rate caused by nitrogen loss, improve the nitrogen concentration in the blister packs, and increase production efficiency.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 like Figure 1-2 As shown, this embodiment provides an inflation auxiliary device for a blister packaging machine, including an inflation tray 1 and an inflation base plate 2. The inflation base plate 2 is fixedly connected to the bottom end of the inflation tray 1. A cavity 10 is opened inside the inflation tray 1, and a plurality of slots 4 are opened on the inflation base plate 2. The top of the cavity 10 is connected to a nitrogen source, and the bottom of the cavity 10 is connected to each slot 4. Nitrogen can inflate the blister 5 after passing through the cavity 10 and the slots 4. The direction of travel of the blister 5 is taken as the first direction, and the direction perpendicular to the direction of travel of the blister 5 on the horizontal plane is taken as the second direction. The size of the slots 4 in the second direction is the same as the size of the blister 5 in the second direction. The spacing between the slots 4 and the blister 5 in the first direction is the same as that in the first direction.

[0022] This embodiment provides an inflation auxiliary device for a blister packaging machine. During use, the inflation tray 1 is connected to the inflation base plate 2 to transport nitrogen. Taking the direction of travel of the bubble eye 5 as the first direction, the spacing between the slot 4 and the bubble eye 5 in the first direction is the same. In the second direction, the spacing between the slot 4 and the bubble eye 5 in the second direction is also the same. This ensures that the slot 4 corresponds to the bubble eye 5 in the direction of travel, so that the bubble eye 5 in the direction of travel is always filled with nitrogen. Taking the direction perpendicular to the direction of travel of the bubble eye 5 on the horizontal plane as the second direction, the size of the slot 4 in the second direction is the same as the size of the bubble eye 5 in the second direction. This ensures that the maximum filling requirement of each bubble eye 5 is met during the filling process, providing nitrogen inflation efficiency and reducing nitrogen filling in non-bubble eye 5 positions.

[0023] In one embodiment, the inflatable tray 1 has a tablet reset surface at one end near the starting position of the bubble eye 5, and the distance of the tablet reset surface from the starting position of the bubble eye 5 gradually decreases from bottom to top.

[0024] The inflatable tray 1 is configured such that one end near the starting position of the bubble 5 conveying has a tablet reset surface. The distance of the tablet reset surface from the starting position of the bubble 5 conveying gradually decreases from bottom to top. Thus, the tablet reset surface can reset tablets that are not in a horizontal state to enter the bubble 5 below the inflatable base plate 2, making them horizontal. This prevents tablets from detaching from the bubble 5 during the encapsulation process and can move tablets that are not in the bubble 5 to the inside of the bubble 5 or the outside of the tablet to prevent tablets that have detached from the bubble 5 from damaging the inflatable base plate 2.

[0025] In one embodiment, the tablet's reset surface is a plane.

[0026] By setting the inflatable tray 1 as a plane, it can exert a downward force on the tablet when resetting it, making the tablet less likely to pop out during the resetting process and achieving a better tablet repositioning effect; it can also make the process of moving the tablet out of the tablet plate more gradual and will not damage the tablet.

[0027] In one embodiment, a plurality of guide grooves 3 are provided in the cavity 10, the guide grooves 3 connect the cavity 10 and the slot 4, and the extension direction of the guide grooves 3 is parallel to the tablet reset surface.

[0028] One or more slots 4 can be opened at the bottom of a flow channel 3 along the first direction and the second direction, and the slots 4 are spaced at the same distance from the bubble eyes 5 in the first direction, and the slots 4 are spaced at the same distance from the bubble eyes 5 in the second direction.

[0029] Because the density of nitrogen gas is approximately 1.22-1.25 kg / m³ 3 The density of air is approximately 1.29 kg / m³. 3 Nitrogen has a lower mass than air for the same volume, therefore it is lighter than air. The parallel alignment of the guide channel 3 with the reset surface effectively prevents nitrogen accumulation at the inclined section of the reset surface. Since the cavity 10 extends close to the reset surface, the inclined guide channel 3 completely discharges the nitrogen from the cavity 10 to the inflation base plate 2, preventing nitrogen accumulation near the reset surface and thus avoiding waste.

[0030] In one embodiment, a gas filter 6 is also included. The inlet of the gas filter 6 is connected to nitrogen gas. The gas filter 6 is used to filter nitrogen gas. The outlet of the gas filter 6 is used to connect to the cavity 10.

[0031] Since blister packaging machines are commonly used in the pharmaceutical industry, the gas filter 6 ensures the safety, shelf life, and compliance of pharmaceuticals, food, or medical devices. The gas filter 6 intercepts impurities or bacteria in the nitrogen gas that could contaminate the pharmaceuticals, thus guaranteeing their safety.

[0032] In one embodiment, an intake pressure reducing valve 7 is also included. The intake port of the intake pressure reducing valve 7 is connected to the outlet of the gas filter 6, and the outlet of the intake pressure reducing valve 7 is connected to the cavity 10. The intake pressure reducing valve 7 is used to adjust the pressure of nitrogen.

[0033] The nitrogen pressure inside the external nitrogen gas chamber is 0.15MPa-0.2MPa; the inlet pressure reducing valve 7 adjusts the nitrogen pressure range to 0.03MPa-0.05MPa.

[0034] The inlet pressure reducing valve 7 reduces the pressure of the incoming nitrogen gas. In this drug filling process, the nitrogen pressure is 0.2 MPa. The inlet pressure reducing valve 7 adjusts the nitrogen pressure range to 0.03 MPa-0.05 MPa, which ensures that the nitrogen gas meets the requirements of the drug and production equipment during filling, reduces the occurrence of accidents, and improves the quality and production efficiency of the drug.

[0035] In one embodiment, it also includes an air intake mounting base 8, which is fixedly connected to the inflation tray 1. The air intake mounting base 8 is provided with a mounting cavity, which is connected to the air intake pressure reducing valve 7 and the cavity 10.

[0036] The air inlet mounting base 8 is connected to the blister packaging machine body, providing an installation position for the air inlet pressure reducing valve 7. The air inlet mounting base and the inflation tray 1 are sealed together, and a sealing gasket can be used to seal this to prevent nitrogen leakage and potential safety accidents.

[0037] In one embodiment, a bubble wrap machine guide plate 9 is provided below the inflatable base plate 2, and the bubble wrap machine guide plate 9 is used to receive the bubble holes 5 that need to be filled with nitrogen.

[0038] During the nitrogen filling process, the blister pack 5, after being filled with medicine, needs to be moved onto the guide plate 9 of the blister pack machine and pulled on it for further stretching. During this process, the nitrogen filling work is carried out.

[0039] In one embodiment, the slot 4 is 1 mm along the first direction.

[0040] This embodiment applies to a drug whose tablet dimensions are: diameter Thickness Φ7mm 3.3mm, single board size: length 90mm wide 54mm; Bubble size: diameter Depth Φ10.8mm The 3.8mm diameter bubble 5 is circular, suitable for storing this tablet. The 1mm diameter slot 4 is the optimal size obtained through multiple experiments, which can reduce nitrogen loss. This device is applied to a specific product and is highly specialized. If it needs to be used for other models of products, only the size and arrangement of the slot 4 in the first and second directions need to be changed.

[0041] The specific implementation process is as follows: When the aluminum blister packaging machine is running, the gas filter 6 is opened. Nitrogen gas at 0.2 MPa, after being filtered by the gas filter 6, enters the inlet pressure reducing valve 7, adjusting the nitrogen pressure range to 0.03-0.05 MPa. The inlet mounting seat 8 is tightly installed on the top of the inflation tray 2 and communicates with the inlet groove located inside the inflation tray 2, forming a well-sealed gas passage. The nitrogen gas, after pressure adjustment by the inlet pressure reducing valve 7, enters the inflation tray through the inlet mounting seat 8. Following the flow channels 3 within the inflation tray 2, it gathers in the air cavity between the inflation tray 1 and the inflation base plate 2. Under the positive pressure of 0.03-0.05 MPa nitrogen, it passes through the array of slots 4 in the inflation base plate 2 and is evenly distributed into the formed blister packs 5 for nitrogen filling. This effectively protects the product inside the blister packs 5 with nitrogen, achieving a nitrogen concentration of over 98%, effectively ensuring the quality of the medicine.

[0042] Example 2 This embodiment also provides an inflation device for a blister packaging machine, including a nitrogen source and an inflation auxiliary device for a blister packaging machine as described in Embodiment 1. The nitrogen source is used to communicate with the cavity 10.

[0043] In this embodiment, the nitrogen cylinder is used to supply nitrogen to the inflation auxiliary device of the blister packaging machine in Embodiment 1. The nitrogen source can be a nitrogen cylinder.

[0044] Example 3 This embodiment also provides a blister packaging machine, including a blister packaging machine body and the blister packaging machine inflation device described in Embodiment 2; the blister packaging machine body is used to seal and package products.

[0045] In this embodiment, the blister packaging machine body, together with that in Embodiment 2, performs the function of packaging medicines.

[0046] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
