[0027] Please refer to Figure 4The sorting mechanism 3 comprises a rack 31, a servo motor 32 fixed on the rack 31, a lower extension shaft 33 connected with the output end of the servo motor 32, and a sorting isolation plate 34 fixed on the lower extension shaft 33. The rack 31 is fixed on the extension plate 13. The servo motor 32 is coupled with the controller 23. In this example, the model of the colorimeter 22 is NR10QC, and the model of the controller 23 is S7-200. The end of the sorting isolation plate 34 away from the lower extension shaft 33 extends towards the guide plate 17, so that the sorting isolation plate 34 can be flipped between the two guide plates 17 and guide the PET bottles. The sorting isolation plate 34 is provided with two air blowing devices 35 (the air blowing device 35 can be a blower). The two air blowing devices 35 are symmetrically arranged at the two ends of the sorting isolation plate 34, so that the two air blowing devices 35 can guide the PET bottles on the two sides of the sorting isolation plate 34, respectively. The air blowing device 35 is inclined, and the inclination angle of the air blowing device 35 is 10°-20°.

The PET bottles can be conveyed one by one between the two guide plates 17. In the conveying process, each PET bottle is detected by the colorimeter 22. When the colorimeter 22 detects a PET bottle of a specified color (for example, blue), it transmits an electric signal to the controller 23, so that the controller 23 drives the servo motor 32 to run, drives the lower extension shaft 33 and the sorting isolation plate 34 to run, and moves the end of the sorting isolation plate 34 away from the lower extension shaft 33 into one of the specified positioning ports 18. In this way, the PET bottle can be guided into one of the track grooves 4 by the sorting isolation plate 34. At the same time, the two air blowing devices 35 work in real time. Therefore, when the PET bottle approaches the sorting isolation plate 34, it can be better blown into the track groove 4 under the action of the air blowing device 35, avoiding the trouble that the PET bottle is stuck at the rack 31.
