[0054] Embodiment 1: See also Figure 1 — Fig.21A centrifugal spinning system guided by airflow, the system comprising a spinneret 1, a receiving disc 2 and an air guide device 3; the air guide device 3 comprises a connecting block 31 and blades 32, a plurality of blades 32 are evenly distributed on the outer surface of the side wall of the connecting block 31, the angle between the blades 32 and the axis of the connecting block 31 is an acute angle, and the movement stroke of the connecting block 31 is rotating around its center of circle; one side of the connecting block 31 faces the side of the spinneret 1, and a plurality of blades 32 are evenly distributed on the side wall of the spinneret 1 A wire disc hole 11, in which the middle part of a spinneret 12 is inserted, and a spinneret 13 is provided on one side of the spinneret 12 outside the wire disc hole 11; the movement stroke of the spinneret 1 is rotation around its center of circle; the other side of the spinneret 1 faces one side of a receiving disc 2, and the receiving disc 2 includes a receiving frame 21 and a receiving block 22, the outer surface of the receiving block 22 is connected to the inner surface of the receiving frame 21, the receiving frame 21 is a mesh structure, and the movement stroke of the receiving block 22 is rotation around its center of circle.

[0055] When in use, first make the connecting block 31 rotate along its center, and then the connecting block 31 drives multiple blades 32 to rotate along the center of the connecting block 31 at the same time. When the blades 32 rotate, an airflow toward the receiving disk 2 is generated; then the spinneret 1 and the receiving block 22 are rotated along their centers.
