Sheathed long spindle and quick bobbin change device for high performance fiber weaving

Abstract

The invention provides a rapid bobbin replacing device, and further provides a long spindle with a sheath suitable for high-performance fibre weaving. The long spindle with the sheath in the inventioncomprises a spindle part and the rapid bobbin replacing device; the rapid bobbin replacing device comprises a bracket part and a sheath part; the spindle part is fixedly connected into a thin-wall arc column at the lower end of the bracket part; the sheath part is arranged at the upper end of the bracket part; lug bosses at two sides of a sheath base compress a spring in the deep groove at the upper end of a bracket; up or down brackets are symmetrical to clamping buckles at the lower parts of double lugs, so that the bracket part and the sheath part are connected or separated; a yarn is leaded out from a bobbin; after winding outside several yarn storage tubes for many circles, the yarn passes through two yarn guide wheels of the bracket part, and penetrates a yarn through hole at the upper part of the bracket from outside to inside; then, the yarn is leaded out to a weaving ring from a yarn outlet through a large porcelain eye at the lower end of the sheath part and a small porcelain eye at the upper end of the sheath part; the sheath is a carbon fibre composite material; and the yarn storage tubes are smooth metal tubes capable of freely rotating. The long spindle with the sheath in the invention is suitable for high-performance fibre weaving; furthermore, the bobbin is simple and convenient to replace; and the yarn loading capacity is high.

Description

technical field [0001] The invention belongs to the technical field of braiding equipment, and relates to a braiding spindle with a sheath, in particular to a long spindle with a sheath, which is suitable for high-performance fiber weaving and has a yarn bobbin device for quick replacement. Background technique [0002] In the weaving process, the spindle is the carrier of the weaving yarn. During the weaving process, the spindle moves according to the track on the weaving chassis and the insert or steering block, and the weaving yarn has a certain tension through the take-up and pay-off device of the spindle and converges on the weaving ring to form a braid. [0003] At present, the common spindle in the industry is a short spindle without a sheath, and the yarn outlet of the spindle is far away from the knitting ring. The long spindle of the sleeve has the following disadvantages: (1) The mechanical structure of the spindle has many contact points with the yarn, which is ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in the current industry, short spindles without sheaths are prone to yarn friction fluffing, adhesion and fracture; the existing long spindles with sheaths are not suitable for weaving high-performance fibers such as carbon fibers, and the replacement of yarn bobbins is complicated.
