Abstract

The invention provides a plastic granulating air-cooling hot-cutting device which comprises a discharge mold head, an air cooler, an air-cooling hot-cutting hood body and a material cutting assembly.The air-cooling hot-cutting hood body is a closed elliptical cylinder which is wide upward and narrow downward; the material cutting assembly comprises a motor, a slicer rack mounted at the output endof the motor and a plural of blades mounted on the slicer rack; a cover port is formed in one end surface of the air-cooling hot-cutting hood body, the motor is mounted on the other end surface of the air-cooling hot-cutting hood body, a cover matched with the cover port is arranged on the cover port, the discharge mold head is mounted in the cover in an embedded manner, the plurality of blades are inclined to a discharge face of the discharge mold head, an air inlet and an air outlet are formed in the lower bottom of the air-cooling hot-cutting hood body, and the air inlet of the air-coolinghot-cutting hood body communicates with the air outlet of the air cooler. Compared with the prior art, the plastic granulating air-cooling hot-cutting device provided by the invention is simple in structure, and the maintenance cost of periodically cleaning particles stuck to the air-cooling hot-cutting hood body is cancelled.

Description

technical field [0001] The invention relates to the technical field of plastic granulation, in particular to an air-cooled hot cutting device for plastic granulation. Background technique [0002] In the plastic production process, after the plastic is extruded through the discharge die of the extruder, the rotating cutter is closely attached to the discharge die, and the hot round strips just extruded are directly cut into granules, and then Conveying and cooling pellets. Patent document CN 203344206 U discloses an air-cooled heat-cutting hood. Its working principle is: a Venturi tee is connected under the air-cooled heat-cutting hood, and the high-speed air flow generated by the fan forms a negative pressure at the Venturi tee, and the heat-cutting is formed. The particles fall down to the Venturi tee due to the negative pressure, and are taken away and cooled by the high-speed airflow generated by the fan at the Venturi tee. The disadvantages are: the air-cooled hot-cut...
