The invention discloses a material extrusion and profiling device for large-diameter PE fiber-reinforced pipes. The device consists of a bottom support mechanism, a raw material extrusion mechanism, a heating device, a profiling device and a limiting device, belonging to the field of continuous fiber tape winding reinforced pipe production in plastic pipes. It solves the problems of uneven wall thickness, poor interlayer bonding force and unsmooth pipe wall during the production of winding-molded pipes. Raw materials are processed into a molten state by a melter, and the melt is distributed to a slot die through a distributor. The melt is extruded through the slot die to form a continuous PE tape, which is evenly wound on a round pipe mold by the profiling device. When wound to a certain thickness, a round seam die is activated to wrap the corrugated pipe, which is wound on the round pipe mold at a certain pitch by the limiting device to form reinforcing ribs, finally producing a high-strength winding-molded pipe.
