Flexible package vacuum detection device

The invention discloses a flexible package vacuum detection device, which comprises a vacuum bin, a bin cover, a driving assembly, a sealing joint, a vacuum source, a mounting base, a sliding block, aclamping groove, a pressure sensor, an ejector rod, clamping blocks, a placement space and a reset assembly, and is characterized in that the reset assembly is used for driving the two clamping blocks to be close to each other. The flexible package vacuum detection device has the beneficial effects that the bin cover is driven by the driving assembly to turn over, so that a flexible packaging product is placed at the top of the mounting base, the bin cover is closed, the interior of the vacuum bin is vacuumized through the vacuum source, and when air is reserved in the flexible packaging product and then expands in the vacuum environment, the flexible packaging product expands and then drives the two clamping blocks to get away from each other, the ejector rod abuts against the pressure sensor, the pressure senso
