Description

Technical Field

[0001] The utility model relates to an air column bag air pressure detection device. Background Art

[0002] Air column bags, also known as cushioning air column bags, inflatable bags, bubble column bags, and columnar inflatable bags, are new packaging materials filled with natural air in the 21st century. Air column bags mainly rely on the columnar space formed by plastic film to seal the air, and use the air pressure in the air column to cushion and protect the product. When the air pressure in the air column is insufficient, the protection effect will be greatly reduced or even fail; when the pressure in the air column is too high, the air column bag may burst and lose its protective effect. Therefore, the air pressure value in the closed air column is very important to the function of the air column bag.

[0003] The existing method of testing the air pressure of air column bags is to perform sampling testing on the air columns of the air column bags, and determine whether the air pressure of the air column bags meets the standards through numerical pressure testing of one or several air columns. The test results of this method may not be fully detected, and unqualified products may be easily put into use, increasing the probability of damage to the packaged items. Utility Model Content

[0023] The detection device 21 can adopt a device such as a push-pull force gauge that can detect pressure. The values detected by the plurality of detection devices 21 are obtained by dividing the data detected by each detection device 21 by the number of detection devices 21, so as to obtain the average value of the air columns in the air column bag to be tested, and to judge whether the air pressure of the air columns in the air column bag meets the standard.

[0024] For example, if there are eight detection devices 21, the numerical calculation method is to divide the sum of the values from the first detection device 21 to the eighth detection device 21 by eight, and the average air pressure value of the air columns in the air column bag to be tested can be obtained.

[0025] A plurality of fixing columns 22 extending towards the bearing platform 11 are also fixedly arranged on one side of the test platform 2 facing the base 1.

The positioning plate 3 is slidably arranged on each fixing column 22 at the same time. A limiting block 221 for restricting the positioning plate 3 on the fixing column 22 is fixedly arranged on each fixing column 22. A plurality of positioning holes 31 corresponding to the detection devices 21 one by one and through which the detection ends of the detection devices 21 can pass are arranged through the positioning plate 3. Each positioning hole 31 corresponds to the air column of the air column bag to be tested placed on the bearing platform 11 one by one; it is ensured that after the test platform 2 descends, the detection ends of the detection devices 21 can accurately contact the inflated parts of the air column bag to be tested.
