Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a packaging bag air leakage detection device. Background Art

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. The air tightness and compressive strength of plastic packaging bags have always been important indicators for judging packaging quality. In existing tests, air tightness is generally measured through water immersion tests.

[0003] For example, the utility model provides "a packaging bag leakage detection device", and its announcement number is: CN205426442U. The application includes a base, a bracket, a movable bracket, a first cylinder, a second cylinder and a water tank. The bracket is fixed on the base, and the water tank is placed on the base below the bracket. The first cylinder is fixed downward on the top of the bracket, and the movable bracket is fixed on the end of the piston rod of the first cylinder. The beneficial effect of the utility model is that during the test, the packaging bag to be tested can be placed on the test platform, the second cylinder is controlled to clamp the packaging bag, and the packaging bag is pressurized after being lowered into the water tank. The water immersion depth of the packaging bag can be controlled by the first cylinder, and the pressure strength of the packaging bag can be controlled by the second cylinder. After one experiment, multiple sets of data on the packaging bag changing with water depth and pressure can be measured.

[0004] As can be seen from the above, in the prior art, when using the packaging bag leakage detection device, the packaging bag is pressed into water. After the packaging bag enters the water, due to the lack of a limiting structure, the packaging bag will float and move, resulting in inaccurate detection data.

[0005] In order to solve the above problems, we have made improvements and proposed a packaging bag leakage detection device. Utility Model Content
