10. The package breakage detection method is characterized in that:
step one: the detection frame (21) is in a horizontal state, the pressing plate (91) is positioned at the top of the inner cavity of the detection box (1), the conveying roller (4) rotates to drive the package to enter the detection cavity (10) from the inlet (11), and the package falls onto the detection frame (21);
step two: the sensor at the inlet (11) detects that the package enters from the inlet (11), signals are transmitted to the central control unit (100), at the moment, the central control unit (100) controls the conveying roller (4) to stop rotating, and the lifting mechanism drives the pressing plate (91) to move downwards;
step three: the pressing plate (91) is extruded with the package to deform the package, and the thermal imager (200) detects the change of the ambient temperature of the package and transmits signals to the central control unit (100);
step four: when the thermal imager (200) detects that the gas comprising the interior is sprayed outwards, the central control unit (100) judges that the package is in a damaged state; when the gas is maintained in the package, the central control unit (100) judges that the package is in a sound state;
step five: when the package is damaged, the central control unit (100) controls the motor (24) to rotate anticlockwise, the detection frame (21) rotates anticlockwise around the rotating shaft (211), and the detection frame (21) inclines towards the first outlet (12); when the package is not damaged, the central control unit (100) controls the motor (24) to rotate clockwise, the detection frame (21) rotates clockwise around the rotating shaft (211), and the detection frame (21) inclines towards the second outlet (13);
step six: the cylinder rod of the cylinder (9) is retracted to drive the pressing plate (91) to move upwards, when the package is broken, the package on the detection frame (21) passes through the first outlet (12) to flow to the output frame, and when the package is unbroken, the package on the detection frame (21) passes through the second outlet (13) to flow to the other output frame;
step seven: at the moment, the sensor at the outlet detects that a package passes through and transmits a signal to the central control unit (100), the central control unit (100) controls the motor (24) to rotate, the detection frame (21) is reset to a horizontal state, and meanwhile, the conveying roller (4) is controlled to restart, and the package is conveyed into the inner cavity of the detection box (1).
