Large-stroke friction-free take-up and pay-off mechanism for spindle of knitter

Abstract

The invention discloses a large-stroke friction-free take-up and pay-off mechanism for a spindle of a knitter and belongs to spindle mechanisms of knitters. The take-up and pay-off mechanism comprises a yarn passing device, a support, a reel take-up device and a yarn passing roller device; the yarn passing device is connected with the reel take-up device on the support, and the reel take-up device enables yarn to be always in a proper force tensioning state in a whole knitting cycle; the yarn passing roller device is connected to the portion, at the upper end of the reel take-up device, of the support, the yarn passing device is connected to the portion, on one side of the reel take-up device, of the support, the yarn passing device and the yarn passing roller device have rotation functions and are free of friction with the surface of the yarn, and therefore abrasion of the output yarn is relieved; a connection hole sleeve and a supporting plate which are connected with a spindle shaft are arranged on the portion, at the lower end of the reel take-up device, of the support. The take-up and pay-off mechanism has the advantages that the pay-off distance of the spindle is prolonged by means of take-up and pay-off through a reel, the yarn is uniform in tension, and the mechanism is suitable for two-dimensional or three-dimensional guide rail knitters; the yarn passing device and the yarn passing roller device are both in rotating modes, friction on the surface of the yarn is avoided, and the surface of the yarn is not damaged; product quality is improved.

Description

technical field [0001] The invention relates to a wire take-up and pay-off mechanism for a knitting machine spindle, in particular to a large-stroke frictionless take-up and pay-off mechanism for a knitting machine spindle. Background technique [0002] The high-speed machine spindles generally used on braiding machines, such as figure 1 As shown, including: spindle rod (1-1), bobbin (1-2), thread pendant (1-3), bobbin shaft (1-4), porcelain eye (1-5), brake cutting shaft ( 1-7), brake cutting shaft horizontal pin (1-8), face plate (1-9), outlet hole (1-10) and wire pendant porcelain eye (1-11); There is bobbin shaft (1-4), bobbin (1-2) is sleeved on bobbin shaft (1-4), thread pendant (1-3) is stuck on both sides of spindle bar (1-1), thread pendant (1-3) One end is provided with thread drop porcelain eyes (1-11), and the spindle bar (1-1) is provided with porcelain eyes (1-5). When working, the yarn (1-6) passes through the spindle bar porcelain eyes ( 1-5), and then ben...
