Cam running-needle control mechanism of flat knitting machine

Abstract

The invention relates to a cam running-needle control mechanism of a flat knitting machine, belonging to the technical field of textile mechanical equipment. The cam running-needle control mechanism comprises a flat knitting machine cam plate, a needle-selecting unit which is arranged on a base in a matching way, a knitting needle control mechanism and a jacquard needle control mechanism, wherein the knitting needle control mechanism comprises a herringbone cam, a transfer cam, a left stitch cam and a right stitch cam which are used for running the knitting needle; and the jacquard needle control mechanism comprises a cast-off cam which is used for running the jacquard needle and is fixedly connected with the flat knitting machine cam plate, and a left receiving cam, a left raising cam, a right raising cam and a right receiving cam which are movable and are respectively arranged at both sides of the cast-off cam in a matching way. By using the scheme to manufacture the cam running-needle control mechanism of the flat knitting machine, the invention enables a direct-selection automatic flat knitting machine to have a divided knitting function, and enhances the pattern-knitting capability of the machine. Besides, the up-run distance of the knitting needle in the receiving process is decreased, and the friction between a transfer needle and a receiving needle in the transfer process is reduced, thus the needle consumption is reduced, the cloth is smoother, and the cloth quality of the textile is improved.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and equipment, and in particular relates to a control mechanism capable of minute-needle knitting, producing multi-pattern and flat fabrics, and a triangular needle trajectory with low needle consumption. Background technique [0002] As a big country in the production and export of knitted garments, my country has a huge scale of related industries. With the deepening of the development of the wool knitting industry, the use of hand-operated flat knitting machines to produce sweaters is increasingly difficult to meet the needs of the market due to its labor-intensive, low output per machine, and relatively simple varieties. High-end products and automated production have become a new trend in the sweater industry. trend. Therefore, in recent years, domestic automatic flat knitting machines have developed rapidly, and they are likely to replace manual flat knitting machines and become t...

Problems solved by technology

However, the automatic flat knitting machine is lacking in function. Generally, it only has the basic functions of knitting, transferring, receiving, and tucking on the same needle bed, and does not have the same needles such as minute needle knitting, secondary needle selection, and double-turning. The function of bed knitting needles performing multiple knitting at the same time

Therefore, there are certain limitations in the products produced by this automatic flat knitting machine

At the same time, because the upward position of the extension needle is too high, the wear between the knitting needles is increased, and it is easy to cause more needle consumption and defective pieces
