[0025] Specifically, the PET preform to be blow-molded is placed on the blow head 3 in the feeding area of the conveyor track 1. Then, the servo motor 12 works, and with the cooperation of the conveyor plate 13, the blow head 3 can be conveyed along the conveyor track 1. When the blow head 3 reaches the heating component, the PET preform is heated with the cooperation of the heating component. After being heated, the PET preform continues to move along the conveyor track 1 with the cooperation of the blow head 3. When it reaches the molding mold mechanism 6, the heated PET preform is blow-molded into a bottle at high temperature. The blow-molded bottle enters the shaping mold mechanism 7 for cooling and shaping.
