Yarn feeding device for crochet machine

Abstract

The invention discloses a yarn feeding device for a crochet machine, comprising a yarn feeding seat, wherein a pair of yarn bobbin sleeve seats which are axially symmetrical to each other along the yarn feeding seat are arranged thereon, upright posts are respectively arranged on both sides of the yarn bobbin sleeve seats and are connected by yarn passing flat iron positioned above the yarn bobbin sleeve seats, yarn guiding hooks are respectively arranged at both sides of the yarn passing flat iron, and heads of the yarn guiding hooks are respectively positioned right above the yarn bobbin sleeve seats; and a pair of tensioners which are axially symmetrical to each other along the yarn feeding seat are arranged on the yarn passing flat iron, yarn carriers are correspondingly arranged under the tensioners and are fixed on the yarn feeding seat, and yarn passing ceramic beads are arranged in the center of the yarn passing flat iron. The yarn feeding device for the crochet machine has the advantages of being capable of producing two-tone core-wrapped belt yarn.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and relates to a yarn feeding device of a crochet machine used for double-color core-spun tape threads. Background technique [0002] At present, crochet machines are widely used in the textile field. The yarn feeding device of the crochet machine includes: a yarn feeding seat, a yarn passing tube is arranged on the top surface of the yarn feeding seat, a fixed sleeve is arranged on the top of the yarn passing tube, and the fixed sleeve and the yarn passing tube are threadedly connected. There is a tension device, the tension device is located under the yarn passing bobbin, and one side of the tension device is provided with a yarn passing porcelain bead. The crochet machine with this yarn feeding device structure can feed two yarns at the same time, so it can produce two-color hollow belts, but the production of two-color core-spun belt threads requires the yarn feeding device to feed...

AI Technical Summary

Problems solved by technology

The crochet machine with this yarn feeding device structure can feed two yarns at the same time, so it can produce two-color hollow belts, but the production of two-color core-spun belt threads requires the yarn feeding device to feed three yarns at the same time. The device cannot meet such demands, so the demand for two-color core-spun tape wires cannot be produced
