Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the preferred embodiment of the large overfeed roller on a kind of textile machine of the present invention is described in detail:
[0021] Such as figure 1 As shown, the main body of the large overfeed roller is a concentric steel sleeve outer ring 1, a mandrel 2 and a plastic part 3 that fixes the relative positions of the two. The outer ring 1 of the steel sleeve is a steel cylinder, the outer surface is polished smooth, and the inner wall is provided with internal anti-slip lines 11, which are cross internal threads; the mandrel 2 is a steel round stick shaft, which is concentric with the outer ring 2 of the steel sleeve. There are outer anti-slip lines 21 on the surface of the shaft 2, which are reticular patterns, and the part of the mandrel 2 located in the outer ring 2 of the steel sleeve is polished into a special-shaped shaft 22, which is a section of cylindrical shaft with two short planes on the surface.
