AI Technical Summary

Technical Problem

Current technologies rely on manual visual inspection and water bath methods to test the sealing of room temperature porridge containers, which have problems such as high false negative rates, low efficiency, and potential secondary contamination.

Method used

A device was designed that includes a base, a conveyor belt, a placement tray, a sealing cover, an air pump, and a pressure gauge. The sealing cover and the placement tray form a closed space. The air pump is used to create a vacuum and the pressure drop is monitored in real time. Combined with an electronic scale to detect mass changes, continuous automatic detection of the tank is achieved.

Benefits of technology

It improves testing efficiency, reduces the rate of missed detections, avoids secondary contamination, adapts to various tank models, and ensures consistent testing conditions for each tank.

Abstract

The utility model discloses a sealing quality monitoring device for normal-temperature porridge production. The sealing quality monitoring device comprises a base, conveying belts arranged on the two sides of the base and a support installed on the base. The base is rotatably connected with a placing disc, the support is provided with a first electric push rod, the bottom end of the electric push rod is connected with a sealing cover, the sealing cover moves downwards to be tightly attached to the inner wall of the placing disc to form a closed space, the support is provided with an air pump, the end of the air pump is communicated with the sealing cover through a hose, and the sealing cover is connected with an air pressure detection meter. Real-time pressure monitoring is carried out on the closed detection chamber formed by precise matching of the sealing cover and the placing disc through the air pressure detection meter, a dynamic pressure attenuation curve in the detection process is accurately recorded, and mass change data is synchronously acquired by using the electronic scale, so that a dual detection mechanism is realized, the detection efficiency is greatly improved, and the detection cost is reduced. And the phenomenon of secondary pollution can be effectively avoided.
