Description

Double-needle integrated stocking anti-winding linkage mechanism Technical Field The invention relates to the technical field of textile machinery, in particular to a double-needle integrated stocking anti-winding linkage mechanism. Background In the field of knitting machines, a hosiery machine is a special device for knitting tubular fabrics such as socks. With the progress of textile technology, stocking machines have evolved from the original single-cylinder circular stocking machines to the present double-cylinder circular stocking machines, which are capable of knitting more complex stocking with rib weave and the like. Stockings, in particular knee stockings or overknee stockings, have a great length of the stocking body, which places higher demands on the knitting process and equipment. In the knitting process of the stocking, the stocking body is gradually lengthened and hung below the needle cylinder to form a flexible tubular structure. In the prior art, when the hosiery machine is used for knitting stockings, there is a long-standing problem that is difficult to thoroughly solve, i.e., the hosiery body is entangled and knotted during the knitting process. Specifically, when the hosiery machine starts to knit the sock, the welt and the upper sock leg portion of the sock are rotationally knit under the drive of the needle cylinder. The sock body becomes longer as the knitting length increases. Since the sock itself is knitted from flexible yarn, the lower half (i.e., the middle lower section of the sock body away from the needle cylinder) tends to lag its rotational speed under the force of gravity and inertia, and even stop rotating, from the upper half driven by the needle cylinder. The phenomenon that the rotation speeds of the upper part and the lower part are inconsistent can cause the lower half part of the sock body to twist and fold, further wind with the sock body or surrounding parts, and finally form dead knots. Once winding occurs, the knitting is stopped slightly, manual shutdown is needed for cleaning, and the heavy sock body is provided with folds, silks and even holes which cannot be repaired, so that the quality and the production efficiency of the product are seriously affected. In particular, in a double-cylinder stocking machine, the torsion moment to which the stocking body is subjected is more complicated and the winding problem is more prominent due to the cooperative movement of the two cylinders. In the existing stocking machine design, in order to cope with the problem, operators are usually required to frequently observe, and manual intervention is carried out at the initial stage of winding, so that not only is the labor cost increased, but also the continuous and automatic production of stockings is greatly limited. Therefore, there is a need in the art to develop a linkage mechanism that can effectively prevent stockings from winding during the knitting process, so as to ensure continuity and stability of the stocking knitting process and improve product quality and production efficiency.
