Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , The frame 6 of the spinning machine is provided with a lower guide rail 9 and a dividing plate 7, and a row of spindles 8 are horizontally installed on the lower guide rail 9 and the dividing plate 7. The far end of the spinning frame is a spinning locomotive head 1, and the near end of the spinning frame is provided with an electric control cabinet 5. The drafting device E of the present invention is installed at the middle height position on the worsted spinning machine, and traverses the whole worsted spinning machine. The drafting device E is connected with the upper roving bobbin 4 through the yarn guide rod 3 .

[0019] refer to figure 2 , image 3 , Figure 4 , the drafting device E of the present invention comprises a cradle body 10, a cradle handle 11, a cradle bar 12, a rear top roller 14, a front t...

Abstract

A double-region elastic drafting device of a spinning frame comprises a cradle body (10), a cradle rod (12), a rear upper roller (14), a front leather roller (16), a torsional spring frame (17), a lower pin (18), a front roller (20), an upper pin (23), a leather roller clamp (24), a roller slide base (25), a roller base (28), an upper middle roller (31) and a lower rear roller (33). A long leather ring (19) is arranged on the lower rear roller (33), the lower pin (18) and the torsional spring frame (17) in a sleeving mode. A short leather ring (15) is arranged on the rear upper roller (14) and the upper pin (23) in a sleeving mode, makes friction contact with the portion, on the lower rear roller (33), of the long leather ring (19) and is matched with the long leather ring (19) to form a rear region mechanism of the drafting device (E), the rear region mechanism is connected and matched with a front region mechanism of the drafting device (E), and the double-region elastic drafting device is formed. The upper pin (23) is a spring swing pin. The elastic drafting mode of the leather ring arranged on the rear region mechanism of the drafting device (E) improves rear-region guiding force, speed changing points of fibers become normal, stress of fiber silvers is uniform, slubs of yarn are reduced, spinning quality is good, and production efficiency is high.

Description

technical field [0001] The invention relates to a spinning frame for spinning, in particular to a drafting mechanism for the spinning frame. Background technique [0002] The worsted spinning machine is the main equipment for spinning, which is composed of a feeding mechanism, a drafting mechanism and a winding mechanism. The yarn device is fed into the drafting mechanism, and the strands formed by the drafting mechanism are output by the front roller, spun into spun yarn after being twisted, sent to the winding mechanism, and wound on the bobbin set on the spindle. Wind the strands into bobbins. The drafting mechanism is divided into the front zone and the rear zone. The drafting front zone is composed of the front top roller and the front bottom roller, the middle top roller, the middle bottom roller and the long and short aprons. The drafting rear zone is composed of the middle top roller and the front bottom roller. The middle and lower rollers and the configured long ...
