Surface-textured unwinding wheel for spherical wheel type unwinding mechanism

The invention relates to a surface-textured unwinding wheel for a spherical wheel type unwinding mechanism. The existing unwinding wheel easily causes the wear of the working surface of the unwinding wheel during working process. The worn unwinding wheel can not be continuously used. Since the manufacturing cost of the unwinding wheel is very high, the shaping and grinding costs after wearing are also very high. The surface-textured unwinding wheel comprises a body, wherein the body is provided with two round platforms (3); an integrated rotary shaft is connected between the two round platforms; the main working surfaces of the body are two round-platform inclined surfaces (1) which have patterns; the directions of the patterns are vertical to the rotary shaft of the unwinding wheel, the patterns are 0.2mm in width and 0.1mm in depth, and the distance of the centers of every two patterns is 0.7mm; and the conical angle of the body is 45 degrees, and the rotary deflection angle is 1 degree.
