FIG. 1 shows an embodiment of this invention, in which a screw 6 driven by a rotary drive device 5 is housed in a casing 4 in which a large-diameter cylindrical feeder section 1 and a small-diameter cylindrical nozzle section 2 are integrally connected by a cone section 3. is arranged,
An input port 1 for waste plastic 7 is provided in the feeder section 1.
A is provided. The drive device 5 is configured to drive a screw 6 supported by a bearing 8 at a reduced speed by an electric motor 5c via a sprocket 5a and a chain 5b fitted at the end thereof. The screw 6 integrally connects a screw shaft 9 in the feeder section 1 and a gas venting rod 10 in the nozzle section 2 with a taper section 11 in the cone section 3, and connects the screw shaft 9 to the root of the gas venting rod 10. It is formed by providing a series of screw blades 12 on the outer periphery up to. The waste plastic 7 inputted from the input port 1a is transferred toward the cone portion 3 as the screw blade 12 rotates. The waste plastic 7 is kneaded and compressed in the cone section 3, where part of the plastic with a low melting point is melted by the heat generated, and the molten plastic is used as a binder to be compressed and solidified. As shown in FIG. 2, the screw blade 12 has a notch 12a in the tapered portion 11 to reduce the feeding action and increase the heat generated in the cone portion 3. The compressed and solidified waste plastic 7 is extruded from the tip of the nozzle portion 2 as a molded product 13 having a gas vent hole 13a in the center. The degassing rod 10 has a tapered portion 11 in order to provide a gap with the degassing hole 13a of the molded product 13 to facilitate degassing.
Eccentrically installed at the tip of the The nozzle part 2
A heater 14 is provided on the outer periphery of the cone portion 3 to heat them to an appropriate temperature before starting operation, and this heater 14 is covered with a heat insulating material 15.
