Yarn clamping device for spinning frame

Abstract

The invention relates to the field of spinning, in particular to a yarn clamping device for a spinning frame. The yarn clamping device comprises a yarn winding wheel, a yarn tensioning device and guide frames; the yarn winding wheel and the yarn tensioning device are arranged on a rack; the guide frames are symmetrically arranged on two sides of the yarn tensioning device; a sensing device is further arranged between the guide frames and the yarn tensioning device; the yarn tensioning device comprises a fixed yarn disc, a movable yarn disc and a magnetic rebounding assembly; the fixed yarn disc is fixedly arranged on the rack through a fixing piece; the movable yarn disc can move relative to the fixed yarn disc; a movement adjusting device used for driving the movable yarn disc to move is further arranged on the rack; and the yarn clamping direction between the fixed yarn disc and the movable yarn disc is further perpendicular to the yarn guiding direction between the two guide frames. Through the action of the magnetic rebounding assembly and the movement adjusting device on the movable yarn disc, yarn can be better clamped, so that the situation that the yarn is excessively loosened or excessively clamped is avoided, and smoother operation of the yarn is ensured.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a yarn clamping device for spinning frames. Background technique [0002] The knitting machine is a kind of textile equipment that uses knitting needles to form coils of various raw materials and varieties of yarns, and then connect them into knitted fabrics through strings. The yarn clamping device is used on the knitting machine to ensure uniform yarn tension and maintain yarn An important component of normal conveying, the yarn clamping device of the prior art includes two steel yarn clamping discs fitted adjacently, the two clamping discs are pressed by stage springs, and the yarn passes through the two clamping discs, however , most of the existing yarn clamping devices use compression springs to clamp the yarn, and there will be deviations for a long time, and there is no tension mechanism that can adjust the clamping of the yarn. The problem of excessive looseness or excessive cla...

AI Technical Summary

Problems solved by technology

[0004] According to the above-mentioned patent, the patent realizes the clamping of the yarn according to the upper disc and the lower disc of the clamping disc, and the circular heating tube can also effectively smooth the yarn and improve the smoothness of the yarn. However, this patent does not have a mechanism for adjusting the yarn disc, which tends to loosen or over-clamp the yarn. The yarn clamping disc clamps the yarn through the force of the compression spring, and clamping also occurs Due to the combination of these two problems, there is a need for a yarn clamping device that can adjust the tension of the yarn and ensure that the clamping disc clamps the yarn accurately
