Abstract

In the process of producing needled nonwoven cloth, especially in the process of producing non-woof needled paper-making felt, an embroidery needle with a triangular cross section in a working segment is always adopted, which has a great damage on warp threads. The utility model provides an embroidery needle with an olivary (rhombic) cross section in a working segment in order to avoid or reduce the damage. The strength of needled nonwoven cloth, particularly non-woof paper-making felt in a warp direction can be greatly increased after the adoption of the utility model, the service life of the cloth can be prolonged, and the economic benefit is increased.

Description

Embroidery needle for needling

The utility model relates to a kind of needle fabric production, the pricker of using during particularly needled paper-making felt is produced.

The pricker of using during acupuncture is at present produced, the cross section of its active section is triangular in shape, all has 2～3 zigzag briar tooths in order to consolidation fibre on leg-of-mutton three ribs.In this case, particularly when acupuncture production has only warp thread not have the no latitude needled paper-making felt of weft yarn, though the pricker direction how to arrange, always there is the briar tooth on or two ribs that warp thread is produced heavy damage, reduced to make the warp-wise brute force of woollen blanket, the service life of having reduced woollen blanket.

The purpose of this utility model provides a kind of pricker that can reduce the damage of yarn in acupuncture course.

Feature of the present utility model is that the Cross-section Design with the pricker active section becomes olive shape (prismatic), opens some zigzag briar tooths on two major diameter ribs of this olive shape cross section active section, does not then open briar tooth on two minor axis ribs.

After adopting this pricker, brute force and the quality of making needle punched fabric and particularly do not have the latitude felt are improved.

Accompanying drawing 1 is the structural representation of pricker, and accompanying drawing 2 is a pricker active section part enlarged drawing, and Fig. 3 is olive shape (prismatic) the shape of cross section schematic diagram of the utility model acupuncture active section.

Shown in the figure:

The 1-needle handle

The 2-needle body

The 3-active section

4-zigzag briar tooth.

Below the utility model is described in further detail.The steel wire of getting required diameter cuts off by Len req, and after cold forging, sharpening, temper, active section strikes out olive shape (prismatic), mills out 2～3 briar tooths 4 on two major diameter ribs, remakes quenching, tempering, the processing of turning blue.

Claims

1, a kind of pricker of using in needle fabric is produced is made up of needle handle 1, the needle body 2 and active section 3, it is characterized in that the shape of cross section of described active section 3 is olive shape (prismatic).

2, a kind of pricker as claimed in claim 1 is characterized in that can opening some briar tooths 4 on two ribs of active section major diameter in described olive shape (prismatic) cross section, does not then open briar tooth on two ribs of minor axis.
