Drawing roller of tape yarn warping machine

Abstract

The invention relates to the field of warping machine parts, in particular to a drawing roller for a tape yarn warping machine. The drawing roller comprises a cylindrical drawing roller, wherein step parts are arranged at two ends on the inner wall of the drawing roller; a connecting block is arranged in each step part; the drawing roller is characterized in that inclined mounting grooves with openings are uniformly formed in the outer surface of the drawing roller; guide ribs are embedded into the mounting grooves. The drawing roller has the advantages that the structure of the drawing roller is improved, a plurality of guide ribs are uniformly arranged on the surface of the drawing roller, the contact mode between tape yarn and the drawing roller is changed, the tape yarn is prevented from being twisted on the drawing roller, meanwhile, possible yarn breaking risk caused by increased tape yarn tension is also avoided, and the normal warping operation and the warping quality are guaranteed.

Description

technical field [0001] The invention relates to the field of warping machine accessories, in particular to a traction roller for a flat wire warping machine. Background technique [0002] The flat wire warping machine is used for warping flat wires. In the warping process, in order to ensure the warping quality of the flat yarn on the pan head, the pressure roller is required to cover the flat yarn on the surface of the pan head to prevent the surface of the pan head from being uneven and the thickness of the pan head uneven during the warping process The problem. [0003] The traction roller in the prior art is a roller body, and the surface of the roller body is smooth. When the flat yarn contacts the surface of the roller body of the traction roller, an arc surface contacts between the flat yarn and the traction roller. During the movement of the flat yarn, The flat yarn may be overturned to form a twist. In the prior art, in order to avoid the flat yarn from twisting o...

Problems solved by technology

[0003] The traction roller in the prior art is a roller body, and the surface of the roller body is smooth. When the flat yarn contacts the surface of the roller body of the traction roller, an arc surface contacts between the flat yarn and the traction roller. During the movement of the flat yarn, The flat yarn may be overturned to form a twist. In the prior art, in order to avoid the flat yarn from twisting on the traction roller, it is prevented by increasing the tension of the flat yarn, but the problem caused by increasing the tension of the flat yarn is that The problem of broken wire is prone to occur, and the above problems have affected the warping quality of the flat wire
