Weaving sword head for flat spun gold textile and sword rod loom

Abstract

The invention discloses a weaving sword head for a flat spun gold textile and a sword rod loom, and the weaving sword head comprises a sword casing, a hook and a motion actuating mechanism, wherein, the hook is fixed on the sword casing by a screw; the motion actuating mechanism is installed inside the sword casing; a loose thread guiding apparatus is arranged on the hook; the hook is connected to the motion actuating mechanism; the motion actuating mechanism comprises a yarn clamping head, a brace, a linkage spring seat, a folding apparatus and a compression spring; the hook is connected to the yarn clamping head; the yarn clamping head is connected to the brace; the brace is connected to the linkage spring seat; the folding apparatus is arranged at the central section of the linkage spring seat; and the compression spring is arranged at the end of the linkage spring seat. The weaving sword head is used for processing textiles like metal wire or flat spun gold on a sword rod loom. The weaving sword head for the sword rod loom is safe and reliable, has a simple and stable structure, and can get a stable yarn clamping effect.

Description

technical field [0001] The invention relates to a weft rapier for a rapier loom, in particular to a weft rapier suitable for flat gold silk textiles and a rapier loom. Background technique [0002] The rapier loom is a widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation and high-efficiency production of the shuttleless loom, its positive weft insertion method has strong variety adaptability and can adapt to Weft insertion of various yarns. Along with the development of textile market, textile kind is also constantly increasing, and now common textile has: cotton, wool, fiber crops, silk, man-made fiber, synthetic fiber etc. can be satisfied. But along with the appearance of "metal wire" and "flat gold wire" textiles, the traditional weft-joining rapier can no longer meet the requirements of production and use. The wire diameter range of metal textile wire is generally between 0.03mm-0.04mm, mainly 0.035mm. It is diffe...

AI Technical Summary

Problems solved by technology

Ordinary weft-connecting swords can clamp ordinary textiles to meet the production requirements, but when processing "metal wire" and "flat gold wire" textiles, especially "flat gold wire", the weft yarn will be in the weft insertion position due to insufficient clamping force. Sliding on the way, resulting in weft defects

[0004] like figure 1 and figure 2 Shown: the function of the rapier weft connecting sword currently in use is to clamp and release the yarn on the rapier loom. The process of clamping and releasing the yarn is as follows: when the yarn needs to be released, the release device drives the yarn clamping lever 14 to combine the shaf
