High-elasticity polyester-cotton blended yarn traction device

The utility model relates to the technical field of high-elasticity polyester-cotton blended yarn production, in particular to a high-elasticity polyester-cotton blended yarn traction device which comprises a traction table, metal columns are symmetrically welded to the two sides of the traction table, guide holes are formed in the metal columns, and supporting plates are symmetrically welded to the two sides of one end of the traction table. A winding roller is installed on the supporting plate, a mounting frame is welded to the middle position of the upper side of the other end of the traction table, a bearing hole is formed in the mounting frame, an arc-surface metal table is arranged on the traction table and connected with a metal column, and the metal column makes contact with the ground, so that when blended yarn is pulled and wound, the winding roller can rotate around the axis of the traction table; the traction roller is arranged on the arc-surface metal table, contacts with the arc-surface metal ta
