Yarn guide device for warp knitting machine

Abstract

The invention discloses a yarn guide device for a warp knitting machine, and relates to the field of warp knitting textile machinery. The yarn guide device comprises a yarn feeding mechanism and a conveying control mechanism which are installed on the two sides of the warp knitting machine; the yarn guide device is driven by a motor, and is coordinated and matched with mechanisms such as a yarn guide needle, a latch needle and a sinker and the like for knitting, and a conveying belt drives a yarn guide rod to clamp yarn and convey the yarn to the other end of a needle bed to be connected witha yarn receiving rod to complete yarn feeding when the needle descends to the lowest point; and after a yarn clamp is loosened, the conveying belt reversely sends back the yarn guide rod. At the moment, after a yarn ejecting comb pushes a weft yarn to the needle, the yarn guide rod clamps the yarn again until a knitting needle descends to the lowest point again to form a new coil, a yarn shear shears off the yarn, the yarn ejecting comb retreats, the yarn receiving rod loosens the clamped yarn, weft insertion action is completed under the action of a traction mechanism, and the process is ready to be repeated. Compared with an existing full-width weft insertion device, space is saved, manufacturing is easy, weft is inserted into all rows in a relatively stable state, damage to the weft isavoided to a certain extent, the cloth cover quality is improved, and the product variety is widened.

Description

technical field [0001] The invention relates to the field of warp knitting textile machinery, in particular to a yarn guide device on the warp knitting machine. Background technique [0002] Lining full-width weft yarns into warp-knitted fabrics can endow warp-knitted fabrics with certain special properties and effects. Lining yarns of different extensibility can achieve different lateral dimensional stability of fabrics, and at the same time can improve the coverage and performance of warp-knitted fabrics. Transparency, reducing bulkiness of fabrics. Commonly used in clothing interlining, interior decorations, equipment and packaging and other industrial fabrics. At the same time, the biaxial knitting structure woven with straightened reinforcing yarns is inserted into the warp and weft directions, which can significantly improve the plane mechanical properties of the fabric and meet the special requirements for fabric performance in some fields, such as the aerospace indu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies of the prior art, to provide a yarn guide device on a warp knitting machine, which is used to solve the problems of unstable weft insertion equipment, large floor space and damaged yarns in traditional weft insertion equipment, and to achieve a smooth cloth surface and a Production of fabric products with good mechanical properties to meet market needs
