1. a conic four-piece reciprocating pin scewrod extruder comprises extrusion system and transmission system, and extrusion system comprises screw rod, machine barrel, pin, and screw rod is installed in the machine barrel, is made up of anterior extruding zone, middle part mixer and rear portion feeding section;

  • Pin is installed in the machine barrel inner surface relative with screw rod spiral shell rib;

    It is characterized in that;

    described screw rod is pre-small post-large conical screw, and the spiral shell rib of screw rod extruding zone and mixer periodically is divided into four sea whelks and is staggered along the circumference lead angle;

    The pin passage is made in space in the middle of per two sea whelks;

    Described machine barrel is the side direction dissection type, and the left and right side machine barrel can rotate to an angle respectively by the desktop holder jointed shaft after unscrewing trip bolt;

    Described transmission system comprises transmission case, transmission case comprises power shaft, gear train, oblique angle wheel, connecting rod and swinging axle, the oblique angle wheel is inclined to certain angle with swinging axle and drivening rod rotates, rotate by the gear set drive swinging axle, drive oblique angle crop rotation circular motion simultaneously, the restriction that the oblique angle wheel is subjected to the connecting rod free degree reacts on swinging axle, forces swinging axle to make periodic shift reciprocately;

    The swinging axle of transmission system is connected with the screw rod of extrusion system by adpting flange, and screw rod whenever rotates a circle and makes forward and backward shift reciprocately simultaneously respectively once.
