Winding balance device

Abstract

The invention discloses a winding balance device which can ensure that the tension of yarn is constant in the winding process of spiral lines of the yarn. The winding balance device comprises a tension balancing stand arranged on a machine beam, wherein a supplementary mandrel and at least one inserting hole distributed around the supplementary mandrel are arranged on the tension balancing stand; a supplementary swinging rod and a torsion spring are movably sleeved on the supplementary mandrel; one end of the torsion spring is butted on the supplementary swinging rod, and the other end of the torsion spring is inserted into the inserting hole; a supporting shaft is arranged at the end part of the supplementary swinging rod; and a swinging winding guide wheel is arranged on the supporting shaft. In the winding process of the spiral lines of the yarn, the supplementary swinging rod swings up and down under the action of the torsion spring to ensure that the length of the yarn between the output point and the winding point of a yarn conveying device is always constant, so that the linear speed of the yarn conveying device is constant, and the tension of the yarn is constant, thereby effectively avoiding the periodic uneven twisting and greatly improving the quality of the formed yarn.

Description

technical field [0001] The invention relates to a winding balance device, in particular to a winding balance device for nylon and polyester filaments for weaving cord fabrics when they are twisted by a two-for-one twister. Background technique [0002] When the existing industrial filaments are twisted and produced by two-for-one twisting technology, the twisted yarn is directly output to the winding point after passing through the "overfeeding wheel" yarn feeding device. Driven by the driving force, and the wire moving rod is used for reciprocating wire moving to complete the helical winding of the yarn. Its disadvantage is: the output point of the overfeeding wheel and the two inflection points of the wire moving motion form a triangle, and the yarn swings from one side of the triangle to the other side during the winding process. On the one hand, the yarn tension is changing all the time, the tension at the middle point of forming is the smallest, and it gradually increa...

Problems solved by technology

The disadvantage is: the output point of the overfeeding wheel and the two inflection points of the wire moving motion form a triangle, and the yarn swings from one side of the triangle to the other during the winding process

On the one hand, the yarn tension is changing all the time, the tension at the middle point of forming is the smallest, and it gradually increases to the maximum at the inflection point, which is not conducive to yarn forming

On the other hand, since the length of the yarn is different from the midpoint to the two inflection points, but the amount of yarn supplied by the overfeed wheel itself is the same, and the line speed of the winding process is the same, so the yarn from the midpoint to the inflection point During the reciprocating process, the yarn is forced to slip and pull out from the overfeed wheel, resulting in periodic uneven twist, and the larger the stroke, the more serious the above quality problems
