Energy-saving and low-noise spun yarn tube suitable for high-speed operation

Abstract

The invention discloses an energy-saving and low-noise spun yarn tube suitable for high-speed operation, which is used for solving the problems of low matching precision and high energy consumption of the spun yarn tube. The spun yarn tube comprises a tube body and a tube core; the tube core is positioned at the upper part of an inner hole of the tube body; bottom holes of the tube body and inner holes of the tube core are tapered holes; the bottom holes of the tube body and the inner holes of the tube core are uniformly distributed in a bottom hole longitudinal groove of the tube body and an inner hole longitudinal groove of the tube core respectively; the longitudinal grooves partition the conical inner surfaces of the bottom holes of the tube body and the inner holes of the tube core into a plurality of discontinuous tube body bottom hole circular cambers and tube core inner hole circular cambers respectively; and a central angle alpha corresponding to each circular camber is 20 to 55 degrees. Continuous cambers on the matched part of the spun yarn tube and a spindle are improved as discontinuous cambers, so the phenomenon of low contact precision between the yarn tube and the spindle can be obviously improved, hairiness and end breakage are reduced, the yarn forming quality is improved, and meanwhile the energy consumption and the use of raw materials can be reduced.

Description

technical field [0001] The invention relates to a textile machine part, in particular to a spun bobbin suitable for high-speed operation, which belongs to the technical field of textiles. Background technique [0002] The ring spinning frame in textile machinery is a device that drafts and winds the roving into spun yarns. The bobbin used on the ring spinning frame is the carrier for the winding of the spun yarn. It is driven by the spindle to rotate at high speed. The structural design of the tube is related to whether the spinning frame can achieve high-speed, energy-saving and low-noise operation. Existing spinning frame bobbin is made up of pipe core, pipe hoop and pipe body, and the outer wall of pipe is double-tapered, and pipe hoop is sheathed at the bottom of pipe body. The inner hole of the tube core and the bottom hole of the tube body are combined with the spindle, and the inner hole of the tube core, the bottom hole of the tube body and the spindle are matched b...

AI Technical Summary

Problems solved by technology

The inner hole of the tube core and the bottom hole of the tube body are combined with the spindle, and the inner hole of the tube core, the bottom hole of the tube body and the spindle are matched by a tapered surface. Due to the manufacturing error, the bobbin is actually in line contact with the spindle during high-speed rotation, so As a result, the contact accuracy is not high, the cooperation with the spindle is not tight enough, and the tube is easy to jump, which in turn affects the yarn quality of the spinning frame, causing problems such as many broken ends and large hairiness.

In addition, the weight of the existing bobbin is relatively large, the noise and energy consumption are large during spinning, and the consumption of raw materials during manufacturing increases the production cost of the enterprise.

Furthermore, the double-taper tube body structure and the tube screen structure of the existing bobbins also increase the difficulty of bobbin manufacturing
