Electromagnetic swing yarn guide needle device used for double-needle-bed warp knitting machine

Abstract

The invention provides an electromagnetic swing yarn guide needle device used for a double-needle-bed warp knitting machine, which is characterized by comprising a bearing seat, a swing piece, an L-shaped yarn guide needle and an electromagnetic control part. The bearing seat is fixed on a guide bar plate of the double-needle-bed warp knitting machine, the electromagnetic control part is arranged in a cavity of the bearing seat, the top end of the swing piece is connected with the electromagnetic control part, the upper portion of the swing piece is rotationally connected with the bearing seat, and the bottom end of the swing piece is connected with the L-shaped yarn guide needle. Connecting yarns can be inlaid on edge knitting needles in a front needle bed working area and a rear needle bed working area alternatively by the electromagnetic swing yarn guide needle device according to knitting process, so that seamless cylindrical warp-knitted fabrics or seamless ultra-wide full-width fabrics are formed after fabrics are taken off the machine. Connecting seams of a front fabric and a rear fabric are in weaving structures identical with twice or more guiding fabrics, and the bottleneck problem of existing double-needle-bed warp knitting process is solved.

Description

technical field [0001] The invention relates to an electromagnetic swing guide needle device used on a double-needle bed warp knitting machine, which belongs to the technical field of textiles. Background technique [0002] Compared with the circular knitting machine, the advantage of the double needle bed warp knitting machine is that it is easy to change the size of the product, and can knit multiple products of different specifications at the same time, with fast machine speed and high production efficiency. When using a double-needle bed warp knitting machine to knit cylindrical fabrics or extra-wide fabrics, the front and rear needle beds use 1-2 ground bars to knit plain fabrics, and at the same time guide needles are arranged at the edge of the fabric to weave side seams , to join the front and rear fabrics into cylindrical products or super wide open fabrics. However, once the bar on the existing warp knitting machine is configured according to the process, the fron...

Problems solved by technology

[0004] The object of the present invention is to provide an electromagnetic swing guide needle device used on a double-needle bed warp knitting machine to solve the problem of knitting two-bar and above cylindrical products and ultra-wide flat flat The technical problem of the seam of the fabric meets the yarn covering or clamping process requirements of the front and rear bars required for the weaving seam of the structure of the second comb and above, eliminates the wrinkles that appear at the front and rear joints of the fabric, and improves the quality of the fabric. The seam strength of the double needle bed fabric enhances the aesthetics and comfort of the product
