Piezoelectric swing yarn guide needle device for double-needle-bed tricot machine

Abstract

The invention provides a piezoelectric swing yarn guide needle device for a double-needle-bed tricot machine. The piezoelectric swing yarn guide needle device comprises a support seat, a swing plate and an L-shaped yarn guide needle, wherein the support seat is fixedly connected with a combing plate of the double-needle-bed tricot machine, the upper end of the swing plate is fixed in the support seat, and the lower end of the swing plate is connected with the L-shaped yarn guide needle. With the piezoelectric swing yarn guide needle device, connecting yarns can be padded on edge knitting needles alternatively in front and rear needle bed working areas according to the needs of the knitting technology, so that a seamless cylindrical warp knitting fabric or a seamless superwide flat fabric is formed after the fabric is off the machine. The connection seams of the front and rear fabrics has a textile structure completely consistent with fabrics with two combs or more than two combs, and the bottleneck problem of the existing double-needle-bed warp knitting process is overcome. Warp knitting fabric knitted by adopting the piezoelectric swing yarn guide needle device disclosed by the invention can be used as tubular warp knitting composite materials for decoration, garment and various industries.

Description

technical field [0001] The invention relates to a piezoelectric type 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 fr...

Problems solved by technology

[0004] The purpose of the present invention is to provide a piezoelectric type swinging 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 super-wide products on a double-needle bed warp knitting machine The technical problem of the seam of the open width 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, and eliminates the wrinkles that appear at the front and rear joints of the fabric. Improve the seam strength of double needle bed fabrics, enhance the aesthetics and comfort of the product
