Problems solved by technology

In traditional ring spinning, part of the twisting in the triangular area is realized by the ring traveler. The twisting effect of this method is not ideal, and there may be uneven twisting, resulting in uneven yarn thickness. At the same time, twisting Insufficient cohesion of the yarn will result in insufficient

Embodiment 1

[0034] refer to Figures 1 to 4 , which is the first embodiment of the present invention, provides a drafting self-twisting device. The drafting self-twisting device A includes a support unit 100 and a self-twisting unit 200 .

[0035] The support unit 100 is an installation bracket of the self-twisting unit 200, and can be used for the external installation of the drafting self-twisting device A. Specifically, support plates 101 are symmetrically arranged on both sides of the support plate 101. Mounting groove 101a. The support plate 101 is a plate body arranged in parallel, the self-twisting unit 200 is installed between the two parallel support plates 101 , the installation groove 101 a is opened at the free end of the support plate 101 , and the installation groove 101 a penetrates the plate body of the support plate 101 .

[0036] The self-twisting unit 200 is used for twisting after the yarn is drawn. Specifically, the self-twisting unit 200 is arranged between the two ...

Embodiment 2

[0045] refer to figure 1 , 5 and 6, for the second embodiment of the present invention, a drafting self-twisting device is provided. In addition to the drafting self-twisting device A including the supporting unit 100 and the self-twisting unit 200 in the above-mentioned embodiment 1, An aggregation unit 300 is also included.

[0046] The collecting unit 300 is used for combing and collecting after the yarn is drawn and before twisting; specifically, it is arranged on the side wall of the support plate 101, and includes a support table 301 and a collector 302 arranged on the support table 301, The output end of the collector 302 is matched with the input end of the self-twisting drum 201 . The support table 301 is connected to the end side wall of a support plate 101 for supporting and installing the collector 302, and the collector 302 is used for combing and collecting the drawn yarns so that they can enter in a predetermined twisting direction in the self-twisting drum 2...

Embodiment 3

[0052] refer to Figure 7 , is the third embodiment of the present invention, this embodiment provides a ring spinning frame, the ring spinning frame is installed with the drafting self-twisting device A in the above-mentioned embodiment 2, and is arranged in the drafting self-twisting device A between the stretching device 400 and the yarn guide 500.

[0053] Further, the roving S is wound on the roving roller, drawn out through the yarn guide rod, introduced into the drafting device 400 from the bell mouth, drawn out after drafting, and passed out from the drafting self-twisting device A to form the spun yarn X, The spun yarn X is finally wound on the take-up roll via the yarn guide.

[0054] The drafting self-twisting device A is set between the drafting device 400 and the yarn guide 500, its input end receives the yarn drawn and output from the drafting device 400, and its output end will complete the self-twisting yarn Yarn output.

[0055] Specifically, the roving S i...

Abstract

The invention discloses a drafting self-twisting device and a ring spinning frame thereof, wherein a support unit in the drafting self-twisting device is provided with support plates symmetrically on both sides, and installation grooves are opened in the support plates; The twisting unit is arranged between the two support plates, and includes a self-twisting drum and a rotary bearing located at the end of the self-twisting drum. The self-twisting drum is connected to the installation groove through the rotary bearing; the collection unit is arranged on the support On the side wall of the plate, it includes a support table and a collector arranged on the support table, and the output end of the collector matches the input end of the self-twisting drum; the driving of the drafting self-twisting device in the present invention comes from the linear drawing. The stretched yarn, the yarn passes through the self-twisting drum, drives the rotation of the self-twisting drum, and completes the even twisting of itself. The assembly unit can improve the twisting of the drafting whiskers, making the yarn smooth and strong; The ring spinning frame equipped with the device can overcome the shortcomings of the original drafting and twisting effects.

Description

technical field [0001] The invention relates to the technical field of spinning devices, in particular to a drafting self-twisting device and a ring spinning frame thereof. Background technique [0002] Ring spinning is the most common spinning method on the market today, and ring spinning is also the most widely used yarn. In the process of ring spinning, the roving is first drafted by the roller, then forms a loose fiber bundle in the jaws of the front roller, and forms a spun yarn through the twisting action of the triangular area, and finally is driven by the traveler and wound onto the bobbin. Although ring spinning is very mature, with the development of modern technology, ring spinning has gradually revealed some deficiencies, such as low spinning speed, more labor, and high production costs, so there have been a variety of new spinning methods. , including air spinning, electrospinning and friction spinning. [0003] Twisting is to increase the strength and wear re...
