The invention provides an extrusion system device for machining reinforced materials. By means of the extrusion system device, a machined product is good in isotonicity, the liquidity of the product in the die pressing process is good, and the load of a threaded rod is reduced. The extruder system device for producing the reinforced materials comprises a twin-screw extruder; the twin-screw extruder comprises a hopper-shaped feeding port; continuous filaments are from a continuous filament supporting rack; part of the continuous filaments enter a fixed-length cutting machine for being subjected to fixed-length cutting, the other part of the continuous filaments are heated through heating equipment, and then the heated continuous filaments and the fixed-length cut filaments enter the twin-screw extruder through the hopper-shaped feeding port to be mixed with and dispersed with thermoplastics polymers. The continuous filaments entering the twin-screw extruder are twisted to broken and dispersed through the threaded rod inside the twin-screw extruder. The continuous filaments twine with one another and are overturned and bent inside the twin-screw extruder, the isotropy of the product is guaranteed, the flatness is good, the liquidity of the product in the die pressing process is increased through the fixed-length cut filaments, the filaments are distributed more uniformly in the product, and the bearing capacity of the produced product is higher.
