Yarn pressing device of computer flat-knitting machine

Abstract

The invention provides a yarn pressing device of a computer flat-knitting machine. The computer flat-knitting machine includes a guide rail and a yarn nozzle base, wherein the yarn nozzle base is arranged on the guide rail in a left-and-right moving mode; the upper portion of the yarn nozzle base is fixedly provided with a pair of yarn nozzle base palping feet different in direction, the space between the pair of yarn nozzle base palping feet is configured into a shuttle changing sliding block cavity, the lower portion of the yarn nozzle base is provided with a yarn feeding nozzle guide rod, the lower portion of the yarn feeding nozzle guide rod is provided with a yarn feeding nozzle, and the yarn pressing device includes a yarn pressing plate base, a yarn pressing tongue plate fixing rod and a yarn pressing tongue plate; a yarn pressing tongue plate base is cooperated with the guide rail at the position corresponding to the front side of the yarn nozzle base in a sliding mode, the upper portion of the yarn pressing tongue plate base is fixedly provided with a pair of yarn pressing tongue plate base palping feet different in direction, the space between the pair of yarn pressing tongue plate base palping feet is configured into a direction-change block cooperation cavity, the upper end of the yarn pressing tongue plate fixing rod is fixed with the middle position of the side, back on to the guide rail, of the yarn pressing tongue plate base, the lower end of the yarn pressing tongue plate fixing rod stretches to the lower portion of the yarn pressing tongue plate base, and the yarn pressing tongue plate is fixed to the lower end of the yarn pressing tongue plate fixing rod. The weaving quality of a metal fiber fabric is ensured.

Description

technical field [0001] The invention belongs to the technical field of computerized flat knitting machines, and in particular relates to a yarn pressing device of a computerized flat knitting machine. Background technique [0002] As known in the textile industry, because metal fibers have unique properties and wide applications like organic and inorganic fibers, specifically, metal fibers have good electrical conductivity, thermal conductivity, magnetic conductivity and high temperature resistance, so metal fiber fabrics such as anti- Radiation fabrics, anti-electromagnetic fabrics, fireproof fabrics, etc. are deeply favored by people. Implanting high-tech brushed metal fibers into fabrics can form high-grade fabrics with good added value. Metal fiber textile fabrics are usually mainly polyester-cotton, nylon-cotton, nylon-polyester, and cotton metal fiber fabrics, and the mass percentage of metal fibers usually accounts for about 3-8% of the total weight of the fabric. ,...

Problems solved by technology

[0003] However, in the process of weaving metal fiber fabrics on a computerized flat knitting machine, the following confusions are often encountered: when the yarn feeder feeds the yarn, the metal fiber yarn bulges and floats upward, which affects the knitting needle hook to take the yarn and Loops will eventually affect the quality of the fabric and even cause scrapping, and the faster the weaving speed, the more serious the yarn floats
