Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a bottle mouth sealing detection device. Background Technology

[0002] In the bottled product manufacturing industry, bottle mouth sealing testing is a key step in ensuring product quality, directly affecting the preservation, leak prevention, and safety of the contents. For food and beverage products, good sealing can prevent the intrusion of oxygen, moisture, and microorganisms, avoiding oxidation, deterioration, dampness, or contamination of the contents. For pharmaceutical bottled products, sealing is necessary to prevent the medicine from reacting with external gases, ensuring the stability of the medicine's efficacy.

[0003] A bottle mouth sealing test device, disclosed in Chinese Patent No. CN203965100U, includes a water tank, an air needle, a connecting tube, and a low-pressure air source. The air needle is tightly connected to the low-pressure air source via the connecting tube. A handle is attached to the connection between the air needle and the connecting tube, and a pressure detector is mounted on the connecting tube. This invention quickly and accurately detects the bottle mouth sealing by injecting gas into a bottle placed in water and observing whether bubbles are generated. The handle at the connection between the air needle and the connecting tube facilitates operation, and the pressure detector on the connecting tube prevents the bottle from bursting due to excessive pressure.

[0004] Traditional testing devices often have an integral water tank for airtightness testing. If a single tank leaks and causes local water contamination, the entire tank of water needs to be replaced or purified. This is not only time-consuming and labor-intensive, but also reduces production efficiency due to downtime. It is difficult to meet the testing needs of multiple varieties and fast pace in mass production. Utility Model Content

The multiple side vertical grooves 7 are arranged in a ring at equal intervals, and a water-proof inner plate 8 is slidably engaged with the outer end of the side vertical grooves 7. Sealing water-blocking contact strips 9 are fixedly connected to the end of the inner water plate 8 away from the rigid column 6 and the inner wall of the side vertical groove 7, respectively. A matching inner ring 5 is fixedly connected to the lower end of the pressing top cover 4. Multiple annularly spaced extension rods 17 are fixedly connected to the lower end of the matching inner ring 5. A hollow pressure panel 11 is connected to the lower end of the extension rod 17. Multiple hollow pressure panels 11 and the corresponding water-proof inner plate 8 are arranged in a cross-interval manner. Multiple hollow pressure panels 11 extend into the airtightness testing water tank 3.

[0023] Please see Figures 2-4 An arc-shaped handle 15 is fixedly connected to the upper end of the pressing top cover 4. Side protruding ear blocks 12 are symmetrically fixedly connected to the left and right ends of the pressing top cover 4. Hollow vertical sleeves 13 are fixedly connected to the inner ends of the side protruding ear blocks 12. Two vertical side guide columns 14 are fixedly connected to the upper end of the testing equipment base 1. The two vertical side guide columns 14 are located on the left and right sides of the airtightness testing water tank 3, respectively. Two hollow vertical sleeves 13 are slidably connected to the corresponding vertical side guide columns 14. A sealing ring 16 is fixedly connected to the outer end of the rigid column 6. The inner walls of the opening of the airtightness testing water tank 3 of the sealing ring 16 are in contact with each other. An intelligent control panel 2 is fixedly connected to the front end of the testing equipment base 1. A pump is connected to the airtightness testing water tank 3. The model can be an XD-40 rotary vane vacuum pump. The airtightness testing water tank 3 is filled with pure water up to two-thirds full. The water level is located below the water-proof inner plate 8.

[0024] The operator lifts the pressing top cover 4 using the arc-shaped handle 15. At this time, the side protruding ear blocks 12 at both ends of the pressing top cover 4 drive the hollow vertical sleeve 13 to slide upward along the vertical side guide column 14. When the pressing top cover 4 is lowered, the hollow vertical sleeve 13 slides down along the vertical side guide column 14, and the matching inner ring 5 fits tightly with the sealing thick ring 16 at the opening of the airtightness testing water tank 3, so as to achieve overall sealing of the water tank.

[0025] The working principle of this utility model is as follows: During testing, the equipment uses the testing equipment base 1 as the installation foundation, and the airtightness testing water tank 3 at its upper end is the core testing area. The tank is pre-filled with pure water to two-thirds full, with the water level below the water-proof inner plate 8. The pressure inside the tank is adjusted by an external pump. Before testing, the operator lifts the pressing top cover 4 using the arc-shaped handle 15. At this time, the side protruding ear blocks 12 at both ends of the pressing top cover 4 drive the hollow vertical sleeve 13 to slide upward along the vertical side guide column 14, opening the airtightness testing water tank 3. The bottle to be tested is inverted, with the bottle mouth facing down, and inserted into the outside of the rigid column 6. The bottle body is placed in the gap between the water-proof inner plate 8 and the hollow pressing panel 11. Multiple water-proof inner plates 8 slide and engage with the rigid column 6 through the side vertical grooves 7. The spacing can be adjusted according to the bottle size. At the same time, the interior of the airtightness testing water tank 3 is divided into multiple independent water storage and testing spaces. The sealing water-blocking contact strip 9 ensures... To ensure the airtightness between the spaces and prevent water from flowing between them, when the top cover 4 is lowered, the hollow vertical sleeve 13 slides down along the vertical side guide column 14, and the matching inner ring 5 fits tightly with the sealing thick ring 16 at the opening of the airtightness testing water tank 3, achieving overall sealing of the water tank. At the same time, the extension rod 17 at the lower end of the matching inner ring 5 drives the hollow pressure panel 11 to move down, and cross-fits with the water-proof inner plate 8 to press the bottle body, preventing the bottle body from floating during testing. After the test is started, the intelligent control panel 2 sets the pressure parameters, and the pump pressurizes or evacuates the airtightness testing water tank 3. The airtightness of the bottle opening is judged by observing whether bubbles are generated in the water of the corresponding independent space. If the bottle opening is not sealed well, gas leakage will form visible bubbles in the water of that space. If the seal is good, no bubbles will be generated. When an independent space is contaminated due to bottle leakage, other spaces remain clean due to the isolation effect of the water-proof inner plate 8, and testing can continue, avoiding contamination of the entire water tank.
