The speed of the conveyor belt 402 is adjusted through the operation panel 2. When the plastic mouthwash cup is transported to the middle of a group of protective boxes 407 inside the automatic detection box 1, the conveyor belt 402 is decelerated, and the motor 419 is started by pressing the operation panel 2 to drive the two groups of moving blocks 410 to move toward each other, so that the arc-shaped clamping block 415 connected to one end of the adjusting rod 412 moves toward each other.

The sensor on the outer wall of the tension plate 509 is used for detection, so that the force of the plastic mouthwash cup can be detected. By transmitting data to the electronic display screen 3, it is convenient for people to use. After the detection, the plastic mouthwash cup is transported on the surface of the conveyor belt 402 through the two sides of the protective frame 401. The infrared scanner 406 on the side scans the label, and the qualified ones are scanned with fonts, and the unqualified ones are scanned without fonts, so that the plastic mouthwash cups after defect detection are transported to one end of the conveyor belt 402, and the labels are detected and scanned by the monitor 607, and the signal is transmitted to the receiver 609, and the control plate 608 is used to move the qualified ones to the qualified plastic product placement box 603 for storage, and the unqualified plastic products are moved to the unqualified plastic product placement box 604 for storage, which saves time and labor, is simpler to operate, and is convenient for improving the convenience of automatic detection of plastic product defects.
