Planetary gear 13, hollow shaft 10, sun gear 12 and planet carrier 11 constitute planetary gear train and are connected with motor 15 by hollow shaft 10, and sun gear 12 can rotate around hollow shaft 10, and planetary gear train is arranged on the frame 9, and wire The material 5 passes through the hollow shaft 10 and moves axially. The hollow shaft 10 drives the planetary gear 13 to rotate around the sun gear 12 through the planet carrier 11, and the planetary gear 13 drives the driving wheel 1 to rotate. The motor 15 drives the hollow shaft 10 through the belt transmission mechanism A16, the shaft coupling 17 and the belt transmission mechanism B19. Driven by the planetary wheel 13, the two driving wheels 1 are driven by themselves and revolve around the wire 5 so as to drive the two abrasive belts 7 to grind the wire 5 at all angles.

Referring to FIG. 4 , in order to further improve the grinding quality, considering the limitation of the width of the abrasive belt 7 , two sets of planetary wheel type double abrasive belt wire grinding mechanisms 14 are designed as a whole. The two groups of grinding mechanisms 14 are equipped with abrasive belts 7 with different roughnesses to achieve continuous grinding of the wire. The power of one group of grinding mechanism 14 is transmitted to planetary gear train A21 by motor 15 through belt transmission mechanism A16, coupling 17, belt transmission mechanism B19, and the power of another group of grinding mechanism 14 is passed by motor 15 through belt transmission mechanism A16, coupling Shaft device 17, power transmission shaft 18, belt transmission mechanism C20 are delivered to planetary gear train B22. After the wire material 5 is polished by the first group of grinding mechanism 14, it is passed out directly from the center of symmetry of the abrasive belt 7, that is, the through hole of the hollow shaft 10, and enters the second group of grinding mechanism 14 to realize continuous grinding.
