[0027] In this embodiment, when using this device, the distance between the two conveyor belts 5 is adjusted according to the size of the packaging box. Motor 2 is then activated, and its output drives the bidirectional screw 3 to rotate. The rotation of the bidirectional screw 3 causes the two threaded blocks 4 to move closer or further apart along the screw, thus adjusting the distance between the two conveyor belts 5. The bottom sides of the packaging box to be inspected are then placed above the two conveyor belts 5. The output of cylinder push rod 7 moves the straightening plate 8 to straighten and limit the packaging box, ensuring it maintains a straight trajectory. When the packaging box enters the inspection box 9, the conveying is paused, and cylinder push rods 10, 13, and 16 operate simultaneously, driving the top pressure plate 11, side pressure plate 14, and bottom pressure plate 17 simultaneously. The movement of the packaging box compresses all surfaces, causing pressure sensors 12, 15, and 18 to detect pressure changes on the surface in real time and transmit the pressure data to the control and analysis system. The control and analysis system analyzes the received pressure data and compares it with preset pressure standards. If the pressure data is within the normal range, the packaging box is determined to be undamaged. If abnormal pressure data is detected, the control and analysis system immediately determines that the packaging box is damaged, moves the box down, and then the cylinder push rod 19 moves the carrier plate 20 to the rear of the damaged packaging box. Then, the motor 21 drives the bidirectional screw 22 to rotate. The rotation of the bidirectional screw 22 can drive two T-shaped pressure plates 23 to clamp the packaging box between them, and the damaged packaging box is discharged through the discharge ladder 31.
