Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bottled food detection, in particular to a sealing detection equipment for bottled blueberry sampling inspection. BACKGROUND

[0002] It is known that blueberries are rich in anthocyanins, vitamin C and other antioxidant ingredients, but when exposed to oxygen, these ingredients will be oxidized, causing the fruit color to darken, nutrients to be lost, and taste to be poor. In order to transport and store for a long time, nitrogen filling is a necessary preservation means, which can significantly reduce the risk of deterioration, and the sealing property is detected after nitrogen filling in bottles to avoid leakage of the contents or leakage of external air to cause oxidation and deterioration of the internally stored blueberries.

[0003] The existing technology has the following problems: the existing sealing detection methods for bottled food are mostly underwater bubbling method, pressure drop method or helium mass spectrometry leak detection method, but most of them need to puncture, heat or soak the bottle, which is easy to cause pollution or is difficult to clean and recycle, and if the popular underwater detection method is used, the drainage and drying processes will also affect the detection efficiency. Based on the above-mentioned problems, we found that the sealing detection equipment of the prior art is difficult to avoid the above problems at the same time, therefore, we propose a sealing detection equipment for bottled blueberry sampling inspection which has strong adaptability, high detection efficiency, and will not cause damage and pollution to the bottled products with good sealing property. SUMMARY

[0004] (I) Technical problems solved In view of the shortcomings of the prior art, the present application provides a sealing detection equipment for bottled blueberry sampling inspection, which has the advantages of strong adaptability, high detection efficiency, and will not cause damage and pollution to the bottled products with good sealing property.

[0005] (II) Technical solutions The above technical purposes of the present application are achieved by the following technical solutions: a sealing detection equipment for bottled blueberry sampling inspection, comprising an outer frame and an inner frame, the top of the outer frame is fixedly connected with a protective cover, the top of the inner frame is fixedly connected with an extension frame and a vacuum pump, the inner side of the extension frame is fixedly connected with a neck pipe, the inner side of the neck pipe is installed with a detection disc, and the top of the detection disc is provided with a bottle rack; The detection disc comprises a clamping pipe, the inner side of the clamping pipe is clamped with a silica gel sleeve, the inner side of the silica gel sleeve is provided with a bottom sheet, the outer side of the silica gel sleeve is provided with a limiting disc, the top of the limiting disc is fixedly connected with a pulling frame, and the inner side of the pulling frame and the top of the silica gel sleeve are fixedly connected; The bottom of the clamping pipe is fixedly connected with the neck pipe, the inner side of the neck pipe is installed with a pressure sensor and a pressure maintaining valve, and the bottom of the neck pipe is fixedly connected with the input end of the vacuum pump.

[0006] The above technical solution is adopted, by setting an outer frame to cooperate with the inner frame, the detection structure and the fixed structure of the product bottle are installed respectively, and an extension frame is set to install and support the neck tube. By setting a bottle rack, it is easy to fix and move the product bottle. When in use, the bottle rack can clamp the bottle body of the product bottle with the bottle mouth facing down, and drive it to the top of the detection disk, and then press it down vertically. Since the pulling frame of the detection disk pulls the top part of the silicone soft cover, its top opening is larger, and the bottle cap and part of the bottle body continue to fall along the silicone soft cover. The part that is not pulled by the pulling frame has an interference fit with the bottle body, and is deformed and stretched when the bottle body passes through, until the bottom of the bottle cap contacts the position of the bottom film, and the bottom film and the silicone soft cover at the bottom part of the bottom film are attached to the top of the limit plate.

If the pressure is stable and the pressure inside the soft sleeve remains unchanged during the pressure-holding period, there is no leakage at the joint between the bottle cap and the bottle body. If the pressure increases during the pressure-holding period, there is a leakage at the joint between the bottle cap and the bottle body, and the gas or liquid in the bottle flows into the soft sleeve through the gap, causing pressure changes to quickly detect the sealing of the bottled blueberries. At the same time, it will not cause puncture damage or contamination to product bottles with good sealing performance. Since there is no contact with liquid throughout the process, there is no need to scrub and dry the surface. After the test is completed, gas is directly blown in through the vacuum pump to maintain normal pressure between the silicone soft sleeve and the bottle body. The bottle rack will transport the bottle body out of the structure again for subsequent random inspection, eliminating the need for drainage and other processes. At the same time, since the silicone soft sleeve allows a certain degree of deformation, the bottle rack can clamp and fix product bottles of different sizes, so it is suitable for most bottled blueberry products.
