Spinning polished rod spindle

Abstract

The invention discloses a spun yarn polished rod spindle, which comprises a rod-disc combination and a spindle base, and includes a yarn winding ring and a supporter, one end of the yarn winding ring is a positioning sleeve fitted on the spindle disk, and the other end of the yarn winding ring is One end is a winding bobbin; one end of the winding bobbin is provided with an end face circular platform connected to the positioning sleeve, the lower end of the yarn bobbin extends into the winding bobbin and the lower end surface of the bobbin contacts the end face circular platform, the The other end of the winding bobbin is provided with a blade; the supporter is set on the spindle rod above the spindle disk of the rod-disk combination; the invention not only has good working reliability, but also can realize the automatic collective doffing of the traditional short spinning machine , to solve the technical problems of high cost and low efficiency in manual doffing; and the manufacturing cost is low, which is suitable for mass production and processing.

Description

technical field [0001] The invention relates to the field of spinning machinery, in particular to a smooth rod spindle for spun yarn. Background technique [0002] Such as Figure 8 As shown, there is no doffing head retention device on the spun smooth rod spindle in the prior art, and manual doffing is generally adopted manually. When doffing and pulling out, the tail yarn on the bobbin falls off several times and is wound on the spindle bar, and the tail yarn is torn off by manual pulling action; when the empty bobbin is inserted, the empty tube presses the tail yarn left on the spindle bar, When the spindle is started, the bobbin is driven to rotate, and the yarn count is rewound on the bobbin to complete the end-retaining process. The manual doffing method not only consumes a lot of labor costs, but also has low efficiency. When the spindle rotates, the bobbin sky eye on the bobbin and the upper end of the spindle bar contact and frictionally transmit torque to drive t...

AI Technical Summary

Problems solved by technology

However, there are still a large number of old-fashioned short spinning machines equipped with polished rod spindles in textile mills, which are far from reaching their service life. Replacement will not only increase costs, but also cause waste of resources. Therefore, it becomes difficult to transform traditional short spinning machines into automatic collective doffing Very necessary, but there is no effective improvement scheme in the prior art
