Abstract

A wire winding mechanism capable of making the spring wire material ends automatically rotate comprises a plurality of pairs of wire feeding wheels (6) which are parallelly arranged on a machine body. The wire feeding wheels (6) in symmetrical arrangement respectively rotate in the positive direction and in the reverse direction for pushing the wire material (5) to move towards an outlet opening through a front wire guide plate (8), and a wire winding device is arranged on the machine body and in front of the outlet opening of the wire material (5). The wire winding device comprises a wire winding shaft (3) capable of being driven to rotate by motive power, a wire winding seat (4) is fixed on the wire winding shaft (3), and a pin shaft (7) is eccentrically arranged on the wire winding seat (4). The wire winding mechanism has low manufacture cost and is favorable for being popularized.
