Description

Technical Field

[0001] The utility model belongs to the technical field of leakage detection instruments, and in particular relates to a soft bag packaging sealing integrity leakage detection instrument. Background Art

[0002] A leak detector is an instrument tool for detecting gas leakage concentration. Leak detection covers a wide range: leak detection instruments, leak detection equipment, leak detection service provision, and leak detection evaluation; leak detectors can check leaks in pipelines for air, gas, steam, liquids, and various equipment.

[0003] The authorization publication number "CN205002935U" records "a leak detection device for flexible packaged products, including a frame and a pressurizing device. The pressurizing device is a cylinder piston assembly that can continuously apply pressure to the flexible packaged products. The fixed end of the cylinder piston assembly is fixedly connected to the frame. The frame is also fixedly provided with a detection platform for placing the flexible packaged products to be detected. The cylinder piston assembly is connected to a pressure gauge for detecting the cylinder pressure. The cylinder piston assembly is used for pressurization. Since the cylinder assembly itself has the characteristic of maintaining pressure, it can continuously output pressure. Pressure testing of the packaging bag for a certain length of time can more thoroughly detect whether there is a leak in the package; and the connected pressure gauge is used to detect the cylinder pressure change, thereby showing the pressure change in the packaged product pressurized by the cylinder, thereby accurately reflecting the sealing leakage of the flexible packaged product. The reading of the pressure gauge replaces the direct observation of the worker by the leak, which is more reliable and saves manpower."

[0004] The above patent can replace the direct observation of leaks by workers through the reading of the pressure gauge, which is more reliable and saves manpower. However, in the prior art, when detecting leaks in soft packaging bags, the leak detection device is required to sense the surface of the soft packaging bags so that the leak detection device can achieve the effect of detecting the soft packaging bags, which affects the detection efficiency during batch detection.
