Pattern bar yarn guide of warp knitting machine

Abstract

The invention discloses a pattern bar yarn guide of a warp knitting machine. The pattern bar yarn guide comprises a needle rod, a needle head and a needle stand. One end of the needle head is provided with a guide hole, the other end of the needle head is inserted in and connected with the inner hole of the end of the needle rod, and the needle rod and the needle stand are separate bodies and permanently connected with each other; the inserted joint point of the needle head and the needle rod is provided with at least one pressing embedded part that permanently connects the needle head and the needle rod. The needle rod and the needle stand can be inserted and arranged in the groove of the needle stand by the driving fit of the narrow part of the needle rod, or in the way that a close-fitting pin roll is arranged in a locating needle rod hole and a locating needle stand hole; the pressing embedded part can be formed in the way that the bulge projected from the outer side surface to the circumference surface of the inner hole of the needle rod is jogged with the drop pit of the circumference surface of the needle head or the circumferentially-extended notch of the circumference surface of the needle head. The invention has the advantages that the needle head is not easy to fall off the needle rod, and under the situation that the needle head, the needle rod or the needle stand is destroyed, only the destroyed one needs to be replaced; in addition, the manufacture is convenient, the production cost is low, the service life is long, and the yarn guide can be promoted to be used on the warp knitting machine.

Description

technical field [0001] The invention relates to a warp knitting machine, in particular to a comb yarn guide used on the warp knitting machine. Background technique [0002] There are mainly two kinds of comb yarn guides used on warp knitting machines. The needle seat and needle bar of a kind of yarn guide are integral parts, and the needle bar and needle head are split. One end provided with a guide hole is plugged into the inner hole at the end of the needle bar, and an adhesive is applied to the joint between the needle head and the needle bar to fix them together; the yarn guide with this structure, one On the one hand, because the yarn passing through the needle guide hole exerts a downward pull on the needle during weaving, the needle often falls off the needle shaft when the binder polymer is aged, etc., and this This kind of shedding is difficult to be found before starting the machine or during weaving, which often results in defective fabrics and damages the econom...
