Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing testing, specifically a multi-station sealing testing device that is matched with a sealing tester. Background Technology
[0002] Food packaging plays a vital role in modern life. It is not only the "outer garment" of goods but also an important carrier for ensuring food safety, facilitating daily life, and transmitting information. The airtightness of food packaging is a key factor in ensuring food safety, quality, and shelf life. Currently, most airtightness testing instruments use the underwater bubble method. The principle is as follows: the sample is placed in a transparent sealing device, which is then filled with a certain amount of water, completely immersing the sample. A vacuum is then created in the sealing device. If the sample fails to meet the requirements, bubbles will form under pressure, which can be observed from the outside of the transparent vacuum chamber. However, when multiple samples are tested simultaneously in current airtightness testing instruments, the samples tend to pile up, making it impossible to observe which sample is leaking, significantly impacting testing efficiency. Utility Model Content

[0006] Furthermore, a handle is provided on the top plate, and feet are provided on the bottom plate.
[0007] Furthermore, it also includes a sealing cover connected to the top of the sealed tank, the sealing cover being connected to a pressure plate via a pressure plate connecting column, the pressure plate being located above the multi-station support.
[0008] Furthermore, the pressure plate has multiple through holes.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] This embodiment discloses a multi-station sealing test device, such as... Figure 1 , 7 As shown, it includes a sealed tank 10, a sealing cover 8 connected to the top of the sealed tank 10, and a base 11 connected to the bottom of the sealed tank. The sealed tank 10 is equipped with a multi-station support 5, such as... Figure 2 , 3As shown, the multi-station support includes a top plate 17, a bottom plate 18, and multiple independent workstations 13. Each independent workstation 13 is tubular, with one end connected to the top plate 17 and the other end connected to the bottom plate 18, and is provided with a sample loading / unloading opening 14. Ventilation openings 12 are provided at the locations where the top plate 17 and bottom plate 18 connect to the independent workstations. In this embodiment, the multiple independent workstations 13 are arranged in a circumferential shape between the top plate 17 and the bottom plate 18, and a support column 15 is provided between the top plate 17 and the bottom plate 18. A handle 4 is provided on the top plate 17, and feet 6 are provided on the bottom plate 18. The multi-station support 5 has multiple independent workstations 13, allowing for simultaneous testing of multiple samples. The sample loading / unloading opening 14 facilitates sample loading and unloading. The sample is constrained within the independent workstation 13 by its own buoyancy, and is not clamped by external forces, maintaining a natural state within the independent workstation 13. Each independent workstation 13 has a vent 12 above it. If a sample leaks and bubbles are generated, they will float to the surface through the vent 12 above the independent workstation 13, making it easier to identify which sample is leaking. The multiple independent workstations do not affect each other. There are two handles 4 above the top plate 17, so your hands will not get wet when picking up or putting down the multi-workstation support.
[0024] like Figure 1 , 4 As shown, the sealing cover 8 is connected to a pressure plate 3 via a pressure plate connecting column 2, and the pressure plate 3 is located above the multi-station support 5. The pressure plate 3 has multiple through holes. The sealing cover 8 is equipped with a sealing cover handle 7 and a 360° rotating quick-connect connector 1, and a sealing ring 9 is provided at the connection point between the sealing cover 8 and the sealing tank body 10. Figure 5 As shown, a sealing groove 19 is provided at the connection between the sealed tank body 10 and the sealing cover 8, and the sealing ring 9 is located in the sealing groove 19.
[0025] The bottom of the sealed tank 10 is screwed with a base plate 11, such as... Figure 6 As shown, the chassis 11 includes an inner disk 20 and an outer disk 21, and the bottom of the sealed tank 10 is screwed between the inner disk 20 and the outer disk 21.
[0026] The multi-station testing device described in this embodiment can be placed on a sealing tester or on other platforms, and connected to the sealing tester via a 360° rotating quick-connect connector 1 and an air tube.
[0027] When testing a single sample, the multi-station support 5 is removed and not used. A certain amount of water is injected into the device, with the water level exceeding the pressure plate 3. The sample is placed into the device, and the sealing cover 8 is placed on top. The pressure plate 3 on the sealing cover 8 will completely press the sample into the water. The pressure plate 3 has multiple through holes, which reduces resistance when submerged in water and effectively removes air bubbles. The sealing cover 8 and the sealing tank 10 have a sealing ring groove 19 of the same size at the sealing point. After the sealing ring 9 is installed, it can both provide a seal and position the sealing cover 8. The inside of the device is evacuated. If there is a leak, air bubbles will be generated. The main body of the device is made of transparent material, which can be easily observed from the outside.
[0028] When testing multiple samples simultaneously, a certain amount of water is injected into the device, with the water level submerging the top plate 17 of the multi-station support 5. The multi-station support 5 is then removed from the device. Two handles 4 are installed on the top plate 17 of the multi-station support to prevent hands from getting wet when handling the support 5. Between the top plate 17 and the bottom plate 18, there are multiple independent tubular stations 13 arranged around the outer edge of the top plate's arc. Each independent station 13 has a sample handling opening 14 at its lower end. Both the top plate 17 and the bottom plate 18 have perforated designs 16, which reduce resistance when submerged in water and effectively allow air to escape. If a sample leaks, it will be discharged through the vent 12 above the independent station, without interfering with other samples. Multiple support columns 15 are located between the top plate 17 and the bottom plate 18 for support. Feet 11 are installed below the bottom plate 18 to prevent scratching the sealed container 10. Except for the handles 4 and feet 6, the multi-station support is made of transparent material. The sample is placed into the sample loading / unloading opening 14 of the independent station 13, and then the multi-station support 5 is placed into the device and submerged in water. The sealing cover 8 is then placed on top. The sealing tester evacuates the multi-station sealing test device. If the sample leaks, the air bubbles will be discharged from the vent 12 of the independent station 13. The multi-station sealing test device has a 360° rotating base plate 11 at the bottom, which allows the device to be rotated horizontally, providing a better view of the internal condition of the device.
[0029] The above description is only the basic principle and preferred embodiment of this utility model. Any improvements and substitutions made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
