Embodiment 1

[0024] The pricking needle includes a needle body 1, on which thorn hooks 2 are arranged at intervals, and the thorn hook 2 includes hook grooves 3 and barb thorns 4, and the hook thorns 4 cut into the needle body 1 and contact the hook groove 3, and three protrusions are arranged on the hook groove 3. The curved surfaces 5, three convex curved surfaces 5 are arranged in parallel along the direction of the joint axis of the barb 4 and the hook groove 3, and the borders of adjacent convex curved surfaces are in contact. The chord length corresponding to the convex arc surface in the middle is greater than the chord length corresponding to the convex arc surfaces on both sides, and the ratio of the corresponding chord lengths is 2. Three convex arc surfaces 5 are also arranged on the barb, and the hook teeth 2 are arranged on all edges of the needle body 1 . All the convex arc surfaces 5 are arc-shaped.

Embodiment 2

[0026] It is basically the same as Embodiment 1, except that the chord lengths corresponding to the convex arc surfaces on both sides are greater than the chord lengths corresponding to the convex arc surfaces in the middle, and the ratio of the corresponding chord lengths is 3.

Embodiment 3

[0028] It is basically the same as Embodiment 1, except that the lengths of the chords corresponding to the three convex arc surfaces 5 are the same.

Abstract

The invention relates to equipment for producing woven fabrics, in particular to a component of a needling machine. A prickling needle comprises a needle body, wherein the needle body is provided withprickling hooks at intervals; each prickling hook comprises a hook slot and a hook prickle; the hook prickle cuts into the needle body and then contacts with the hook slot; and the hook slot is at least provided with two convex cambered surfaces. The prickling needle greatly reduces the possibility of needle breakage, and prolongs the service life of the prickling needle.

Description

technical field [0001] The invention relates to a device for producing woven cloth, in particular to a part of a needling machine. Background technique [0002] The hook teeth on the traditional lancets are impacted and pressed by a tool similar to a chisel. The hooks produced inevitably have right angles, acute angles, and planes. These right angles, acute angles, and planes have the following defects on the fibers that are hooked: [0003] 1. As a result, the sliding resistance of the fibers between the barbed hooks will be increased, and the resistance of the needles during the weaving process will be increased, resulting in excessive broken needles. [0004] 2. Because the sliding resistance of the fibers between the barbed hooks is large, the direct contact with the high-speed moving fibers at right angles will generate force, which will cause fiber damage and breakage, resulting in uneven surface of the woven product, reduced fiber entanglement, and vertical and horizo...
