Food packaging bag sealing performance detection device

The utility model discloses a food packaging bag leakproofness detection device, which comprises a base, a pressing mechanism and a heating mechanism, through the arranged pressing mechanism, a food packaging bag needing leakproofness detection can be put into a detection barrel filled with test water, then a motor is started, a rotating screw is driven by the motor to rotate, and the food packaging bag is heated by the heating mechanism. The lifting disc drives the overwater pressing disc to move downwards to extrude the food packaging bag in the detection barrel into water to be completely immersed, at the moment, whether continuous bubbles are generated in the water or not can be observed, and whether the packaging bag is in a sealed state or not can be detected; according to the device, the heating ring can be started through the controller, water in the detection barrel is heated through the heating ring, the sealing effect of the packaging bag in a high-temperature environment can be tested, and the tes
