Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection, in particular to an air tightness detection device for canned quality inspection. Background Art

[0002] Canned food is a packaging method that can effectively extend the shelf life of food. During the canned food packaging process, the can body and the packaged canned food need to be tested for air tightness. The air tightness test of the can body is carried out before packaging, mainly to detect whether there are defects such as gaps and pores caused by processing defects in the can body production process. The canned food after packaging is mainly tested on the sealing area to avoid leakage caused by incomplete sealing.

[0003] In the prior art, the air tightness detection of canned food is roughly the same as that of the can body, which is to put the entire can body into a closed space and then pressurize the closed space. After maintaining the pressure for a period of time, the air pressure change is observed. If the air pressure drops significantly, it means that the high-pressure gas has escaped into the can body and the can body is not airtight. On the contrary, if the air pressure drop is within an acceptable range, it means that the can body is well sealed (because the detection device itself cannot be absolutely sealed, so a small amount of pressure loss is normal). The disadvantage of this detection method is that the space for accommodating the entire can body is relatively large, resulting in a long inflation time, which affects production and detection efficiency.
