Guiding piece suitable for rapier loom and used for guiding weft insertion device

Abstract

Disclosed is a guiding piece suitable for a rapier loom and used for guiding a weft insertion device. The guiding piece is characterized in that the lower portion of the guiding piece is provided witha connecting base, the connecting base is provided with a clamping groove and a bolt connecting hole which are both connected with a sley, the upper portion of the guiding piece is provided with a guiding groove, and the guiding groove bends and extends towards one side vertically upwards from the upper middle portion of the guiding piece and is of an opening structure; the front end of the uppergroove wall of the lateral opening end of the guiding groove is provided with a yarn splitting top tip (12), the yarn splitting top tip (12) is composed of left and right guiding surfaces (4 and 5) and is of a wedge-shaped structure, and the outer edge of a horizontal section (1) located at the rear portion of the yarn splitting top tip (12), the outer edge of an arc transition section (2) and the outer edge of a lateral edge (3) are all of curved-surface structures; a front tip (11) of the lower groove wall of the lateral opening end of the guiding groove and the outer edge extending from the front tip to the lower portion of the inner side are provided with guiding conical edges (10) formed by left and right guiding surfaces (8 and 9); left and right flat surfaces (6 and 7) of the guiding piece form two lateral guiding surfaces.

Description

technical field [0001] The present invention relates to a kind of textile machinery, in particular to a kind of weft insertion mechanism with guide sheet used in the weaving of thin sensitive fabrics by rapier looms, the key parts of which are used to guide the weft inserter, weft picker, etc. Guide blades for conveyors and conveyor belts. Background technique [0002] Rapier looms are used to weave fine-denier sensitive jacquard fabrics, and are generally equipped with weft insertion mechanisms without guide hooks. Since the mechanism has no guide hook, the influence of the guide hook on the warp is eliminated, and it can adapt to the weaving requirements of various jacquard fabrics. However, since there is no guide hook to support the weft insertion device, the strength and rigidity of the weft insertion part need to be strengthened, resulting in an increase in the size of the weft insertion part, an increase in accessories, an increase in the cost of the mechanism, and a...

AI Technical Summary

Problems solved by technology

However, since there is no guide hook to support the weft insertion device, it is necessary to strengthen the strength and rigidity of the weft insertion part, resulting in an increase in the size of the weft insertion part, an increase in accessories, an increase in the cost of the mechanism, and a lower weaving speed

[0003] Rapier looms weave fine-denier sensitive jacquard fabrics with weft insertion mechanism with guide hooks, because the interference to the warp yarns will seriously affect the inner quality and appearance of the fabric when ordinary guide hooks enter and exit the warp yarns of the lower layer, and cannot adapt to the weaving of fine-denier sensitive jacquard fabrics Require
