The utility model discloses an anti-die hole blocking device for glass fiber reinforced PPS material processing by twin-screw extruder, which comprises an extrusion cylinder. A first mounting plate is fixedly connected to the end of the extrusion cylinder in a sleeving manner, one side of the outer surface of the first mounting plate abuts against a second mounting plate, and connecting mechanisms are symmetrically mounted on the top and bottom of the first mounting plate and the second mounting plate together. A porous plate is fixedly connected to the inner wall of the second mounting plate, and a shearing mechanism is mounted inside the porous plate. In the utility model, through the arranged shearing mechanism, each hole of the porous plate is designed as a tapered hole, and sharp shearing teeth are formed at the large opening edge of the tapered hole, so that uncut glass fibers can be cut off at any time, avoiding a small amount of uncut glass fibers winding between two holes and then gradually accumulating to cause blockage of the porous plate, and ensuring the production efficiency of glass fiber reinforced polyphenylene sulfide (PPS).
