Polypropylene resin screw extrusion device

The utility model discloses a polypropylene resin screw extrusion device which comprises a machine table, a control box, an operation machine, an extrusion device, a heating ring and an extrusion die head, the control box is matched with the machine table to be connected with the operation machine, and the control box is matched with the operation machine to carry out control connection on the extrusion device at the same time. When the raw materials are pushed into the extruder, the raw materials are heated by the heating ring to be in a solid state to be converted into molten mass, then the molten mass is pushed forwards by the spiral scraper on the rotating rod, and the removing mechanism arranged on the rotating rod effectively removes the raw materials adsorbed on the spiral scraper or the pipe wall, so that the raw materials are prevented from being left in the pipe body; and finally, the polypropylene resin which becomes a molten mass is extruded by the extrusion die head along the discharge ring to fi
