Wide-breadth multi-guide-bar jacquard warp knitting machine with yarn pressing plate

Abstract

The invention discloses a wide-breadth multi-guide-bar jacquard warp knitting machine with a yarn pressing plate. The machine is characterized in that the width of the warp knitting machine is at least 240 inches and can reach 268 inches. A slot needle bed, a needle core bed, a knocking-over piece and the yarn pressing plate of the warp knitting machine are all divided into a left part and a right part from the middle. A main beam of the warp knitting machine is jointly supported by a left wallboard, a right wallboard and a middle wallboard. Guide bars include the pattern guide bar, the ground guide bar and the jacquard guide bar. The pattern guide bar transversely penetrates through the middle wallboard along the full width of a needle bed and is installed on a guide bar base, a pattern needle is installed on the pattern guide bar, the pattern needle and the pattern guide bar are assembled and disassembled in a pluggable mode, and the pattern guide bar is driven by a servo motor at one end and a cylinder at the other end to transversely move in an opposite-pull. The ground guide bar and the jacquard guide bar are both divided into a left section and a right section at the position of the middle wallboard, and the transverse movements of the ground guide bar and the jacquard guide bar are driven by guide bar transverse movement devices installed at a machine head and at a machine tail respectively. The middle wallboard is additionally arranged in the middle of a machine table to support the main beam, the span of the main beam is reduced, vibration of the machine table in the operation process is reduced, and the stable operation of the machine table is guaranteed.

Description

Technical field: [0001] The invention relates to a warp knitting machine, in particular to a multi-bar jacquard warp knitting machine with a wide width and a yarn pressing plate, belonging to the field of textile machinery. technical background [0002] The warp knitting machine is composed of main mechanism and auxiliary mechanism, wherein the main mechanism includes: transmission mechanism, loop forming mechanism, let-off mechanism, bar traverse mechanism, pulling and coiling mechanism. Knitting is one of the important processes of fabric formation, and the mechanism that realizes the knitting action is called the knitting mechanism. Its main knitting parts include grooved needles, needle cores, comb bars, strippers, yarn pressing plates, etc. [0003] The multi-bar jacquard warp knitting machine with the yarn pressing plate on the market generally has a width of 132 inches. The output of warp knitting machine is low like this, can not satisfy the demand of client's few ...

AI Technical Summary

Problems solved by technology

The main beam has one more support point, and its span is reduced by 50%, which solves the problem of insufficient rigidity of parts due to large span
