Claims

[Scope of utility model registration request]

An extruder equipped with a discharge die in which a plurality of nozzles are arranged on the circumference, and the extruder is rotatably arranged in opposition to the discharge die of the extruder, and the center of rotation is the center of the circle in which the nozzles are arranged. An air guide tube that is eccentric by a predetermined amount relative to the air guide tube, the front end of the cylindrical body expands into a horn shape, and its terminal end reaches just in front of the nozzle row; a ventilation groove formed at a location other than the ventilation groove forming portion at the terminal end of the air guide pipe and a ventilation shielding portion that is close to the surface of the discharge die and substantially does not allow air to pass through; A rotation driving means for a pipe, an air blower communicating with the rear end opening of the body, and a blower fixed to the outside of the ventilation groove of the air guide pipe, the tip of which is connected to the discharge die by rotation of the air guide pipe. has a cutter that rotates along the surface of the cutter, and an exhaust pipe that communicates with an annular air passage along the locus of the cutter, and air blown by the blower passes through the air guide pipe and substantially only from the ventilation groove. The plastic that is continuously discharged from the nozzle of the extruder is cooled and cut into a predetermined length by the cutter, and the cut pellet-shaped plastic is blown by air discharged from the ventilation groove. An apparatus for producing pellet-like plastics configured to transport the pellets to the exhaust pipe while being cooled and solidified.
