Friction roller of drawing machine

The utility model relates to a friction roller of a drawing machine, which is characterized in that the friction roller is arranged on a frame, a spinning cake and the friction roller carry out winding through friction transmission, and the outer surface of the friction roller is a standard cylindrical arc surface without convex ribs. Therefore, the start-up speed of the spinning cake is even, the initiative speed of tows is reduced at the very beginning of the winding process, and the tensile force of the tows is stable in the rolling process. The friction roller of the drawing machine ensures even tensile force of tows, leads the amount of network points to be even back and forth in the spinning-in and tow falling processes, can meet the actual production demands, solves the existing problem that the network points are uneven back and forth in the former production, improves the processability of the products in the rear procedure, enhances the quality of the products and promotes the market competitiveness
