Abstract

The invention discloses a yarn feeding device capable of preventing the yarn from sliding during the feeding. The yarn feeding device comprises a beam; and a yarn feeding roller and a leather roller fitting each other are movable arranged on the beam. The yarn feeding device composed of the roller and the leather roller feeds the yarn; the yarn is wound on the surface of the leather roller with an iron core when the yarn passes through the roller; the leather roller is driven by the friction transmission between the roller and the leather roller to rotate uniformly so as to drag the twisted yarn to be fed into a winding area; and as the leather roller has enough force to drive the yarn, the yarn is fed at a constant linear velocity, the yarn is prevented from sliding during the feeding and the twist difference and the twist unevenness of the yarn are avoided.

Description

technical field [0001] The invention relates to a yarn feeding device for yarns such as nylon and polyester filaments for weaving cord fabrics when they are twisted by a two-for-one twister. Background technique [0002] When existing industrial filaments are twisted and produced by two-for-one twisting technology, the twisted yarn is transported to the thread delivery device in the winding area, using the "overfeeding wheel" on the traditional twisting machine. The disadvantage of this overfeeding wheel delivery device is that the yarn often slips in the overfeeding wheel, resulting in unstable transmission speed of the yarn, resulting in uneven twist and inconsistent twist between spindle positions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a yarn delivery device that does not slip during yarn delivery. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by t...
