Draft uniformity control mechanism for a spinning frame

By introducing support rings and moving rings into the spinning frame, the instantaneous traction force is distributed, and the sliding friction is reduced by using support blocks and springs, thus solving the problem of uneven yarn drafting and achieving uniform yarn drafting and improved product quality.

AI Technical Summary

Technical Problem

Existing spinning machines cannot make reasonable adjustments at the instantaneous yarn drafting point, resulting in uneven yarn drafting and a tendency for yarn breakage.

Method used

The drafting mechanism of the spinning machine with uniform drafting is adopted, including the support fixed ring and moving ring assembly. By distributing the instantaneous traction force, the sliding friction is reduced by the cooperation of the support block and spring, and the resistance adjustment component is set to improve the rotational smoothness.

Benefits of technology

It achieves uniform yarn drafting, avoids yarn breakage, improves product quality, and reduces fiber wear caused by sliding friction.

Abstract

The application relates to the technical field of drafting mechanisms, and discloses a fine spinning machine drafting regulation and control mechanism with uniform drafting, which comprises a supporting fixed ring, and a movable ring assembly sleeved outside the outer ring of the supporting fixed ring; the movable ring assembly comprises a plurality of splicing components arranged in an annular array and connected in a head-to-tail mode; the drafting mechanism is adopted to distribute a part of the traction force borne by the instantaneous drafting point to the yarn area between the drafting mechanism and the rapid roller, so that the yarn product is uniformly drafted, and the generation of the yarn breakage phenomenon can be avoided; the resistance regulation assembly is designed as an auxiliary assembly capable of rotating the movable ring assembly; when the rotation scheme of the movable ring assembly on the supporting fixed ring is stuck, the rotation scheme of the supporting plate on the annular limiting edge can be used to replace the two schemes or the two schemes are simultaneously used to cooperate, so that the smoothness of the operation of the drafting mechanism is improved.
