[0002] PET preforms are mainly made of polyethylene terephthalate (PET), a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. PET has the characteristics of creep resistance, fatigue resistance, friction resistance and good dimensional stability, low wear and high hardness, and the greatest toughness among thermoplastics.

A flip plate 16 is installed under the movable slide of the No. 2 synchronous belt module 12, and a plurality of No. 2 vacuum suction cups 17 are equidistantly arranged in the middle of the flip plate 16. The sides of the No. 2 vacuum suction cups 17 and the No. 1 vacuum suction cups 11 are fixedly connected with auxiliary partition blocks of trapezoidal structure to increase the stability of the PET preform; a probe 19 is placed at the end of the No. 2 synchronous belt module 12, and is used to perform random inspection on the conveyed PET preforms. The probe 19 is an ultrasonic probe. The signal generated during the probe measurement process will be captured and recorded by the sensor. The acquired signal data needs to be processed and analyzed to extract the thickness, density and other parameters of the PET bottle. The thickness, density and other parameters of the PET bottle are calculated based on the measured signal data and related physical models or algorithms.

[0023] It should be noted that the utility model is equipped with a PLC controller. Under the action of the controller, the No. 2 synchronous belt module 12 drives the No. 2 vacuum suction cup 17 to absorb and fix the PET bottle blank on the conveyor belt and then move to one end along the No. 2 synchronous belt module 12. When the PET bottle blank moves to the bottom of the probe 19, the No. 3 cylinder 14 drives the No. 2 vacuum suction cup 17 to flip, so that the mouth of the PET bottle blank contacts the probe 19, thereby realizing the bottle mouth detection.
