Description

Magnetic suction type composite line drafting device

Technical Field

The utility model belongs to the field of textile machinery, relates to a magnetic suction type composite yarn drafting device, and particularly relates to a drafting mechanical device integrating magnetic suction pressure regulation, curve drafting and double-strand drafting, which is suitable for developing novel drafting devices and yarns in textile enterprises and scientific research institutions.

Background

The drafting occupies an extremely important position in the whole spinning process, and the selection of the drafting multiple in the processes of drawing, roving, spinning and combing plays an important role in the spinning after each process and the quality of slivers. The most fundamental change of the drafting process is that the fibers in the sliver are transversely moved towards two ends, fiber aggregates are straightened, the curls and hooks between the fibers can be slowly eliminated, the size of the fiber aggregates is longer and thinner along with the drafting, and whether the drafting process is good or not is closely related to the quality of finished yarns.

In the prior art, a simple three-roller linear drafting mechanism is invented, and the drafting multiple reaches 6 times. The utility model of simple roller drafting realizes the automation of the drafting process and greatly improves the production efficiency. However, the draw is insufficient in that a floating zone is generated during the drawing, and the existence of the floating zone makes the fibers not controlled by the nip of the rollers, so that the fibers are randomly reinforced. The drafting realizes roller drafting by adjusting the gauge for fibers with different lengths, which lays a foundation for the utility model of hyperbolic drafting. In order to improve the yarn quality, the improvement of the spun yarn drafting area at home and abroad is mainly controlled by changing the length of the floating area of the drafting area. The pressure bar is additionally arranged in the drafting zone of the spinning machine, the control range of the friction force boundary is enlarged by additionally arranging the pressure bar and the distance block in the front zone, the floating zone of the fiber is reduced, more short fibers are effectively drafted, and the resultant yarn evenness is improved. The back area is provided with a new friction force boundary by means of the upper pin of the pressure bar, so that the drafting force of the fiber strand in the back area is increased. The drafting mechanism realizes yarn evenness improvement through curve drafting, and the control on fibers is weaker in the curve drafting process, so that the yarn evenness is not uniform. In order to develop high-quality yarns, the magnetic-type composite yarn drafting device is valuable to research and develop, and can provide reference for the research and development of novel yarns.
