[0003] Patent CN113447217A discloses a sealing inspection unit for a flexible bag packaging system, including a detection tank, a vacuum pump, a top cover, a pressure sensor, a pressure gauge, and an alarm system. The vacuum pump is located on one side of the detection tank, the top cover is located on the top of the detection tank, the pressure gauge is fixed on one side of the detection tank and connected to the pressure sensor, and an installation groove is formed on the inner wall of one side of the detection tank, in which the pressure sensor is installed. A disassembly structure is provided between the detection tank and the pressure sensor. By adding an alarm system to the sealing inspection unit of the flexible bag packaging system, the alarm system will automatically activate the alarm light when a sealing defect is found in the flexible packaging bag during inspection, thereby reminding the operator. This allows the operator to determine whether there is a sealing defect in the flexible packaging bag during daily inspection without repeatedly comparing the values ​​on the pressure gauge, simply by observing whether the alarm light is lit.

The air source is provided by the cylinder's action and the original position air circuit, causing the pressure plate installed on the cylinder to press against the infusion bag. Pressure will be generated during this squeezing process. After the generated pressure is displayed on the pressure gauge, it is maintained for a certain period of time. Then, the infusion bag is removed, and each welding point is observed for any abnormalities. If there are no abnormalities, it is considered qualified.
