Description

Technical Field

[0001] This utility model belongs to the field of barrier bottle production, specifically a barrier bottle sealing performance testing device. Background Technology

[0002] Barrier bottles are containers specifically designed to prevent external substances (such as air, moisture, and gases) from entering the bottle or to prevent leakage of the contents. The sealing test of barrier bottles is a very important process, especially in the pharmaceutical, cosmetic, and food industries, to ensure that the container can effectively isolate the external environment and prevent contamination and leakage.

[0003] In existing technologies, the presence of gas leaks is often observed by filling the barrier bottle with gas to determine the test results. However, gas leaks are difficult to observe visually, which can affect the operator's judgment of the test results. Furthermore, the gas filling test requires sealing the bottle opening before injecting gas, and existing technologies make it difficult to fully seal the bottle opening, causing gas to easily escape from the bottle opening after subsequent filling, thus reducing the accuracy of the barrier bottle test.

[0006] In a preferred embodiment, the transmission assembly includes a first bevel gear and a linkage unit. The first bevel gear is rotatably connected to the top side of the sealing plug via a rotating shaft. A first motor is fixedly connected to the top side of the sealing plug away from the rotating tube via a mounting block. The output end of the first motor meshes with the first bevel gear. A second bevel gear is fixedly connected to the outside of the rotating tube. The first bevel gear meshes with the second bevel gear. A turntable is rotatably connected inside the sealing plug. The turntable is fixedly connected to the outside of the rotating tube. Arc-shaped blocks are fixedly connected at equal intervals to the outside of the turntable. A slide rod is slidably connected at equal intervals inside the sealing plug. A disc is fixedly connected to one side of the slide rod. One end of the slide rod is fixedly connected to a corresponding arc-shaped push plate. A spring is provided outside the slide rod and between the disc and the inner wall of the sealing plug. The pressure plate can be raised and lowered via the linkage unit.

[0007] In a preferred embodiment, the linkage unit includes a lifting plate, which is fixedly connected to the top of the pressure plate. Limiting rods are symmetrically fixedly connected to the top of the sealing plug. The lifting plate is slidably connected to the outside of the limiting rods. The outside of the rotating tube is provided with threads, and the lifting plate is threadedly connected to the rotating tube.

[0008] In a preferred embodiment, the lifting assembly includes a limiting frame, which is fixedly connected to the top side of the base. A lifting frame is slidably connected to the upper part of the limiting frame. The lifting frame is fixedly connected to a sealing plug.

[0009] In a preferred embodiment, a flexible tube is fixedly connected to the top side of the sealing plug via a limiting plate, one end of the flexible tube is rotatably connected to the rotating tube, and an air blower is installed on the top side of the base, with the end of the flexible tube away from the rotating tube fixedly connected to the air blower.

[0010] In a preferred embodiment, the bottle body is detachably connected to the outside of the sealing plug, and the bottom of the rotating tube penetrates the inner wall of the sealing plug and extends to the bottom of the bottle body.

[0011] The beneficial effects of this utility model are as follows:

[0012] This device seals the bottle opening with a first and second sealing gasket. An arc-shaped push plate and pressure plate tightly adhere the first and second sealing gaskets to the inner wall and top of the bottle opening, ensuring a tight seal. This prevents gas leakage during subsequent sealing tests due to insufficient sealing, which could affect the operator's judgment of the bottle's sealing performance. This improves the accuracy and rigor of the bottle testing. Furthermore, by immersing the bottle in water and observing the presence or absence of bubbles, the test results are deduced, enhancing the accuracy and intuitiveness of the test compared to simple inflation testing.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-6A barrier bottle sealing performance testing device includes a base 1, a water tank 2 fixedly connected to the top of the base 1, a sealing plug 3 above the water tank 2, a first sealing gasket 4 fixedly connected to the outside of the sealing plug 3, a second sealing gasket 5 fixedly connected to the top of the first sealing gasket 4, an arc-shaped push plate 6 slidably connected to the outside of the sealing plug 3 at equal intervals, a pressure plate 7 slidably connected to the top of the outside of the sealing plug 3, a rotating tube 8 rotatably connected to the inside of the sealing plug 3, a transmission assembly and a lifting assembly on the top of the base 1.

[0023] Specifically, the transmission assembly includes a first bevel gear 9 and a linkage unit. The first bevel gear 9 is rotatably connected to the top side of the sealing plug 3 via a rotating shaft. The top side of the sealing plug 3 away from the rotating tube 8 is fixedly connected to a first motor 10 via a mounting block. The output end of the first motor 10 meshes with the first bevel gear 9. A second bevel gear 11 is fixedly connected to the outside of the rotating tube 8, and the first bevel gear 9 meshes with the second bevel gear 11. A turntable 12 is rotatably connected inside the sealing plug 3 and is fixedly connected to the outside of the rotating tube 8. Arc-shaped blocks 13 are fixedly connected at equal intervals to the outside of the turntable 12. A slide rod 14 is slidably connected at equal intervals inside the sealing plug 3. A disc 15 is fixedly connected to one side of the slide rod 14. One end of the slide rod 14 is fixedly connected to a corresponding arc-shaped push plate 6. A section is provided outside the slide rod 14 and between the disc 15 and the inner wall of the sealing plug 3. A spring 16 is provided, and the pressure plate 7 can be raised and lowered through a linkage unit. The linkage unit includes a lifting plate 17, which is fixedly connected to the top of the pressure plate 7. A limit rod is symmetrically fixedly connected to the top of the sealing plug 3. The lifting plate 17 is slidably connected to the outside of the limit rod. The outside of the rotating tube 8 is provided with threads, and the lifting plate 17 is threadedly connected to the rotating tube 8. The lifting assembly includes a limit frame 18, which is fixedly connected to the top side of the base 1. A lifting frame 19 is slidably connected to the upper part of the inside of the limit frame 18. The lifting frame 19 is fixedly connected to the sealing plug 3. A lead screw 20 is rotatably connected to the top of the base 1 and located inside the limit frame 18 through a fixed frame. A second motor 21 is fixedly connected to the top side of the base 1. The output end of the second motor 21 is fixedly connected to the lead screw 20. The lifting frame 19 and the lead screw 20 are connected through a lead screw nut pair.

[0024] The above technical solution involves first filling the water tank 2 with an appropriate amount of clean water, then placing the bottle mouth 25 over the sealing plug 3, ensuring the first sealing gasket 4 fits against the inner wall of the bottle mouth and the second sealing gasket 5 fits against the top of the bottle mouth. Next, the first motor 10 is started, its output driving the first bevel gear 9 to rotate. The first bevel gear 9 then meshes with the second bevel gear 11 and the rotating tube 8, causing the rotating tube 8 to rotate the external turntable 12 and the arc-shaped block 13. This allows the arc surface of the arc block 13 to push the sliding rod 14, which in turn drives the corresponding arc-shaped push plate 6 to push and compress the first sealing gasket 4, simultaneously compressing the spring 16 until the arc-shaped push plate 6... The first sealing gasket 4 is pushed to fit tightly against the bottle opening of the bottle body 25, and the bottle body 25 is clamped and positioned by the tension of the arc-shaped push plate 6. During the rotation of the rotating tube 8, the lifting plate 17 can also be driven to move downward under the limit of the limiting rod through the threaded connection, thereby driving the bottom pressure plate 7 to press the second sealing gasket 5, pressing the second sealing gasket 5 to the top of the bottle opening of the bottle body 25. Together with the first sealing gasket 4, the bottle opening of the bottle body 25 is sealed, avoiding gas leakage at the bottle opening during subsequent sealing tests, which would affect the staff's judgment of the sealing test of the bottle body 25, thereby improving the accuracy and rigor of the test of the bottle body 25. When the bottle opening of the bottle body 25 is sealed and the bottle body is... After positioning 25 is completed, the second motor 21 is started. The output end of the second motor 21 drives the lead screw 20 to rotate. The lead screw 20 then drives the lifting frame 19 to move downward under the limit of the limit frame 18 through the lead screw nut pair, until the lifting frame 19 drives the sealing plug 3 and the bottle body 25 to descend into the water tank 2, so that the bottle body 25 is completely immersed in the clear water. At this time, the air blower 24 is started. The air blower 24 blows air and transmits the air through the hose 23 to the rotating tube 8, and then the rotating tube 8 blows the air into the bottle body 25. At this time, observe whether there are bubbles in the water in the water tank 2. If bubbles are generated, it means that the sealing test of the bottle body 25 has failed. If no bubbles are generated, the sealing test of the bottle body 25 has passed. This device seals the bottle opening of the bottle 25 using the first sealing gasket 4 and the second sealing gasket 5. The arc-shaped push plate 6 and the pressure plate 7 tightly adhere the first sealing gasket 4 and the second sealing gasket 5 to the inner wall and top of the bottle opening, ensuring a good seal on the bottle 25. This prevents gas leakage from the bottle opening due to insufficient sealing during subsequent sealing tests, which could affect the operator's judgment of the bottle 25's sealing performance. This improves the accuracy and rigor of the bottle 25's testing. Furthermore, by immersing the bottle 25 in water and observing the presence or absence of air bubbles, the test results can be deduced, which improves the accuracy and intuitiveness of the test compared to simple inflation testing.

[0025] Specifically, a hose 23 is fixedly connected to the top side of the sealing plug 3 via a limiting plate 22. One end of the hose 23 is rotatably connected to the rotating tube 8. An air blower 24 is installed on the top side of the base 1. The end of the hose 23 away from the rotating tube 8 is fixedly connected to the air blower 24. A bottle body 25 is detachably connected to the outside of the sealing plug 3. The bottom of the rotating tube 8 penetrates the inner wall of the sealing plug 3 and extends to the bottom of the bottle body 25.

[0026] Through the above technical solution, the set hose 23 can facilitate the transmission of gas to the bottle 25 after it moves downward, and the rotating tube 8 can transmit the gas to the inside of the bottle 25.

[0027] In use, first, fill the water tank 2 with an appropriate amount of clean water, and then place the bottle mouth 25 over the sealing plug 3, so that the first sealing gasket 4 is in contact with the inner wall of the bottle mouth, and the second sealing gasket 5 is in contact with the top of the bottle mouth. Then, start the first motor 10. The output end of the first motor 10 drives the first bevel gear 9 to rotate. The first bevel gear 9 then drives the second bevel gear 11 and the rotating tube 8 to rotate through meshing. This causes the rotating tube 8 to drive the external turntable 12 and the arc block 13 to rotate. The arc surface of the arc block 13 pushes the slide rod 14 to slide. The slide rod 14 then drives the corresponding arc push plate 6 to push and squeeze the first sealing gasket 4, while squeezing the spring 16, until the arc push plate 6 pushes the first sealing gasket 4 to the bottle body 25. The bottle opening is tightly fitted, and the bottle body 25 can be clamped and positioned by the tension of the arc-shaped push plate 6. During the rotation of the rotating tube 8, the lifting plate 17 can also be driven to move downward under the limit of the limiting rod through the threaded connection, thereby driving the bottom pressure plate 7 to press the second sealing gasket 5, pressing the second sealing gasket 5 to the top of the bottle opening of the bottle body 25. Together with the first sealing gasket 4, the bottle opening of the bottle body 25 is sealed, avoiding gas leakage at the bottle opening during subsequent sealing tests, which would affect the staff's judgment of the sealing test of the bottle body 25, thereby improving the accuracy and rigor of the test of the bottle body 25. After the bottle opening of the bottle body 25 is sealed and the bottle body 25 is positioned, the second motor 21 is started. The output end of the second motor 21 The screw 20 is driven to rotate, and the screw 20, through the screw nut pair, drives the lifting frame 19 to move downward under the limit of the limiting frame 18, until the lifting frame 19 lowers the sealing plug 3 and the bottle body 25 into the water tank 2, so that the bottle body 25 is completely immersed in the clear water. At this time, the air blower 24 is started, and the air blower 24 blows air and transmits the air through the hose 23 to the rotating tube 8, and then the rotating tube 8 blows the air into the bottle body 25. At this time, observe whether there are bubbles in the water in the water tank 2. If bubbles are generated, it means that the sealing test of the bottle body 25 has failed. If no bubbles are generated, it means that the sealing test of the bottle body 25 has passed. This device can seal the bottle mouth of the bottle body 25 through the first sealing gasket 4 and the second sealing gasket 5. Furthermore, the arc-shaped push plate 6 and pressure plate 7 tightly adhere the first sealing gasket 4 and the second sealing gasket 5 to the inner wall and top of the bottle mouth, ensuring the sealing effect of the bottle body 25. This avoids the problem of gas leakage at the bottle mouth due to insufficient sealing during subsequent sealing tests, which would affect the staff's judgment on the sealing test of the bottle body 25. This improves the accuracy and rigor of the test of the bottle body 25. In addition, this device immerses the bottle body 25 in water and infers the test result by observing whether bubbles are generated. Compared with simple inflation test, it improves the accuracy and intuitiveness of the test. The set hose 23 can facilitate the transmission of gas to the bottle body 25 after it moves downward. The rotating tube 8 can transmit the gas to the inside of the bottle body 25.
