[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figure 1-3 As shown, a beverage bottle packaging qualified inspection device, a water tank 1, the water tank 1 is used to store the test liquid;

[0029] A positioning cylinder 2, which is installed inside the water tank 1 and immersed in the detection liquid;

[0030] The annular airbag 3 has an air inlet connected to an air delivery pipe 5. The annular airbag 3 is sleeved on the outside of the beverage bottle to be tested and placed in the positioning cylinder 2. When the annular airbag 3 is inflated, the annular airbag 3 expands in its circular direction to squeeze the beverage bottle to be tested.

[0031] When conducting a sealing test, the annular airbag 3 is mounted on the outside of the beverage bottle to be tested, and then placed in the positioning cylinder 2. Test water is added to the water tank 1 until the beverage bottle is immersed. When the liquid level is stable, the annular airbag 3 is inflated through the gas pipeline 5. Under the limit of the positioning cylinder 2, the annular airbag 3 expands toward its center and squeezes the outer wall of the beverage bottle. If the beverage bottle has a leakage problem, after pressure is applied, the gas in the beverage bottle is discharged from the leakage point, and bubbles can be observed in the test water. The place where the bubbles are generated is the leakage location.

[0032] By using the positioning cylinder 2 and the annular airbag 3 to squeeze the beverage bottle, it can be applied to beverage bottles of different specifications, and at the same time, the fit with the outer wall of the beverage bottle is better, avoiding the impact of local compression and damage on the detection of the beverage bottle.

[0033] In order to limit the annular airbag 3, a plurality of annular limiting grooves 7 are evenly arranged on the inner side of the positioning cylinder 2 along its height direction. After the annular airbag 3 is inflated, the annular airbag 3 sinks into the annular limiting groove 7, thereby preventing the beverage bottle from being tilted due to its skew. In addition, by increasing the groove depth of the annular limiting groove 7, after the annular airbag 3 is placed in the annular limiting groove 7, the expansion direction of the annular airbag 3 is limited under the action of the groove wall of the annular limiting groove 7, so that the annular airbag 3 can better exert pressure on the beverage bottle.

[0034] In some embodiments, in order to further improve the pressure effect, a plurality of protruding capsules 6 are evenly arranged along the circumference of the inner side of the annular airbag 3. When the annular airbag 3 is inflated, the protruding capsules 6 expand and protrude from the outer wall of the annular airbag 3, exerting pressure on the beverage bottle.

[0035] In some embodiments, in order to adapt to different bottle heights, a liftable base 8 is provided on the inner side of the bottom end of the positioning cylinder 2, wherein the positioning cylinder 2 is rotatably connected to the support 4, and a stud 14 is fixedly connected to the bottom end of the base 8, the stud 14 is threadedly connected to the limit edge 9, and the stud 14 is slidably connected to the support 4.

[0036] Since the stud 14 is slidably connected to the support 4 and the stud 14 is threadedly connected to the limit edge 9, the base 8 can be controlled to rise and fall by controlling the forward and reverse rotation of the positioning tube 2, thereby making it more convenient to adjust the height of the base 8.

[0037] Specifically, the stud 14 passes through the support 4 , and a strip groove 13 is formed on the outer side of the stud 14 along its length direction. The support 4 is fixedly connected to the limiting block 12 at a position corresponding to the strip groove 13 .

[0038] Specifically, a limiting edge 9 is provided on the outer side of the bottom end of the positioning tube 2, and a pressure block 10 is provided on the outer side of the limiting edge 9. The pressure block 10 is fixedly connected to the support 4 by bolts, and an annular groove for limiting the limiting edge 9 is formed between the pressure block 10 and the support 4.

[0039] In order to facilitate the inspection of bubbles generated by air leakage, the water tank 1 and the positioning tube 2 are both made of transparent materials. Preferably, the water tank 1 and the positioning tube 2 are both made of transparent acrylic.

[0040] Working principle: When in use, the height of the base 8 is adjusted by rotating the positioning cylinder 2 according to the height of the beverage bottle, so as to facilitate the placement of the beverage bottle to be tested. The annular airbag 3 is sleeved on the outside of the beverage bottle to be tested, and then placed in the positioning cylinder 2. The annular airbag 3 is pre-inflated to expand the annular airbag 3 to fix the beverage bottle to prevent it from floating when water is added.

[0041] Add test water to the water tank 1 until the beverage bottle is immersed. When the liquid level is stable, continue to inflate the annular airbag 3 through the gas pipeline 5. Under the limit of the positioning cylinder 2, the annular airbag 3 expands toward its center and squeezes the outer wall of the beverage bottle. If the beverage bottle has a gas leakage problem, after pressure is applied, the gas in the beverage bottle is discharged from the leaking place, and bubbles can be observed in the test water. The place where the bubbles are generated is the leaking location.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
