Description

Technical Field

[0001] This utility model relates to the field of airtightness testing, and more specifically, to a container airtightness testing device. Background Technology

[0002] Air tightness testing equipment is an instrument used to detect whether a container or product has a gas leak, and it has a wide range of applications in industrial production.

[0003] Existing airtightness testing equipment fills a container with gas at a certain pressure and then immerses it in a test liquid. The airtightness is judged by observing whether bubbles emerge from the surface of the container, and the location of the bubbles indicates the location of the airtightness defect. Existing airtightness testing equipment uses a pressure plate or fixing mechanism to immerse the container in the test liquid to prevent the container from floating out of the test liquid, but the position of the container cannot be adjusted, making it inconvenient to observe all sides of the container.

In addition, the directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. The directional terms are used to better and more clearly explain and understand this utility model, and are not intended to indicate or imply the necessary orientation of this utility model. Therefore, they should not be construed as limitations on this utility model.

[0019] Examples of embodiments of this utility model Figures 1 to 3 As shown, a container airtightness testing device includes a base. A groove 10 is provided on the top surface of the base 1. A first lifting mechanism is provided on the base 1. The lifting end of the first lifting mechanism is connected to a mounting plate 3 located directly above the groove 10. Two first rollers 30 are rotatably arranged at intervals on the bottom surface of the mounting plate 3. The two first rollers 30 are arranged at intervals in the front-to-back direction and extend in the left-to-right direction. A drive mechanism is provided on the mounting plate 3 to drive the two first rollers 30 to rotate synchronously. A lifting plate 4 is provided on the mounting plate 3 to lift and lower directly below the two first rollers 30. Two second rollers 41, corresponding to the first roller 30, are rotatably mounted on the top surface of plate 4. The two second rollers 41 are located directly below the two first rollers 30 and extend in the left and right directions. The mounting plate 3 is provided with a second lifting mechanism that drives the lifting plate to rise and fall. The side wall of the base 1 is provided with an observation window 11 that can observe the situation inside the groove 10. The observation window 11 is located on the front side wall of the base. Preferably, rubber pads are provided on the side walls of the first roller 30 and the side walls of the second roller 41, and the rubber pads are provided with anti-slip stripes to avoid crushing the container and prevent slippage when rotating the container.

[0020] Test liquid is injected into the groove 10. The cylindrical container is placed horizontally on the two second rollers 40. The second lifting mechanism drives the lifting plate 4 to rise, so that the two first rollers 30 and the two second rollers 40 clamp and fix the container. Then, the first lifting mechanism drives the container to fall through the mounting plate 3, so that the container is immersed in the test liquid. Then, the driving mechanism drives the two first rollers 30 to rotate synchronously and slowly at a uniform speed, so that the container rotates slowly, which makes it easy to observe multiple sides of the container. Through the observation window, it can be confirmed whether there are bubbles coming out of the container, which is very convenient.

Through the drive gear 34 and the driven gear 35, the drive motor 32 drives the two first rollers 30 to rotate synchronously and in the same direction.

[0022] Further improvements, such as Figure 1 and Figure 3 As shown, the drive motor 32 is mounted on the top surface of the mounting plate 3. The output shaft of the drive motor 32 passes through the bottom surface of the mounting plate 3 and is connected to a first bevel gear 36. A second bevel gear 37 that meshes with the first bevel gear 36 is provided on the rotating shaft 31. The power of the drive motor 32 located on the top surface of the mounting plate 3 is transmitted to the rotating shaft 31 through the first bevel gear 36 and the second bevel gear 37, thereby preventing the drive motor 32 from entering the test liquid and extending the life of the drive motor 32.

[0023] Further improvements, such as Figure 1 and Figure 3 As shown, the first lifting mechanism includes a bracket 2 and a hydraulic telescopic rod 20.

The plurality of electric telescopic rods 5 are arranged at equal intervals along the circumferential edge of the mounting plate 3. There are two electric telescopic rods 5, which are respectively mounted on the left and right sides of the top surface of the mounting plate 3. The output end of the electric telescopic rod 5 passes through the mounting plate 3 and is connected to the lifting plate 4.

[0025] In a further improvement, the lifting plate 4 is provided with a lifting plate through hole 40 located directly below the two first rollers 30. The two ends of the second roller 41 are rotatably connected to the two inner side walls of the lifting plate through hole 40. At this time, the two ends of the second roller 41 are respectively rotatably connected to the left and right inner side walls of the lifting plate through hole 40, and the two second rollers 41 are respectively located directly below the two first rollers 30.

[0026] Further improvements, such as Figure 1 and Figure 3 As shown, the base 1 has a liquid storage chamber 6 located directly below the groove 10. The bottom end of the groove 10 has a groove through hole 60 communicating with the liquid storage chamber 6. The inner side wall of the groove 10 has a water outlet hole 7 communicating with the outside of the base near the bottom end. Both the groove through hole 60 and the water outlet hole 7 are equipped with solenoid valves 70. The base 1 is also equipped with a water pump 8. The input end of the water pump 8 is connected to the liquid storage chamber 6. Preferably, the input end of the water pump 8 is connected to the liquid storage chamber 6 near the bottom surface of the liquid storage chamber 6, and the output end of the water pump 8 is connected to the inner side wall of the groove 10 near the top end.
