Device for improving surface roughness of bead wire

Provided is a device for improving the surface roughness of a bead wire. According to the device for improving the surface roughness of the bead wire, the bead wire enters a frame to be positioned through a positioning mechanism firstly, it is guaranteed that the bead wire enters the portion between a grinding wheel I and a grinding wheel II in the linear direction, and the eccentric abrasion is prevented; a driving mechanism drives the grinding wheel I and the grinding wheel II to rotate, and the rotating direction is opposite to the advancing direction of the bead wire, so that the bead wireis ground through arc grooves in the grinding wheel I and the grinding wheel II, and the roughness of the bead wire is increased; the ground bead wire is subjected to slag removal through a slag removal mechanism, and the grinding powder attached to the surface of the bead wire is prevented from affecting subsequent fusion with rubber; finally a tension mechanism provides tension, and winding ofa winding machine is facil
