This utility model discloses a hopper device of an injection blow molding machine for producing plastic packaging bottles, which comprises a hopper. A mounting seat is fixedly connected to the outer side of the lower part of the hopper, a driving cavity is arranged inside the mounting seat, and a stirring and anti-blocking component is coaxially arranged inside the hopper. A shell is sleeved on the outer wall of the hopper, a number of electric heating wires are fixedly connected between the inner side wall of the shell and the outer side wall of the hopper, and ventilation holes for air to pass through are arranged on the side wall of the hopper. A material blocking component is arranged on the hopper inside the mounting seat. The utility model realizes drying and preheating treatment of plastic particles in the hopper device by arranging the hopper with ventilation holes, a shell equipped with electric heating wires and a fan, and matching with the material blocking component. The arrangement of the stirring and anti-blocking component in the hopper not only avoids accumulation and blockage during mass feeding, but also facilitates stirring the plastic particles above the material blocking component to realize uniform preheating, which improves the feeding speed and thus meets the production requirements.
