Abstract

A kind of sley point, including pin hole, shank, screens notch, guiding surface, it is characterized in that：Pin hole shape is kidney slot, and bigger than general sley point pin hole, and needle body thickness is thicker than general sley point.The sley point is a kind of sley point of piezoelectric jacquard, is mainly used for cotton yarn, the jacquard weave of wool yarn and big grammes per square metre yarn.

Description

A kind of sley point

Technical field

The utility model belongs to field of textile machinery, more particularly to a kind of sley point of tricot machine piezoelectric jacquard.

Background technology

In textile machinery industry, using more and more extensive, warp knitted jacquard fabric also becomes increasingly jacquard pattern design tricot machine It is universal.Textile fabric it is superfine and it is extremely thick two extremely due to the few corresponding products of technical difficulty.It is thick such as sweater, scarf also Using the weaving loom of pure mechanic structure, flower pattern is single, simple.Common jacquard yarn needle guide is difficult to meet the need of textured yarn weaving It asks.

Invention content

The purpose of the utility model is to overcome the deficiencies of background above technology, provide a kind of sley point, smooth can pass through Thicker yarn, and the requirement of the big output of textured yarn can be met.

The technical solution of the utility model is：A kind of sley point includes：Pin hole, shank, screens notch, guiding surface, It is characterized in：The shape of pin hole is kidney slot.

A kind of sley point of the utility model, the arc radius R of the kidney slot are 0.75-1. 5mm, in kidney slot The heart is 0.3-1.0mm away from d, and the thickness of shank is 0.5-0.6mm.

Specific implementation mode

Below in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

As shown in Figure 1, Figure 2, shown in Fig. 3：Sley point 5 includes pin hole 1, shank 2, screens notch 3, guiding surface 4.Pin hole 1 It sets and widens, in partial view A, the shape of pin hole is kidney slot, and the arc radius R of kidney slot is 0.75-1. 5mm, kidney slot Centre-to-centre spacing d is 0.3-1.0mm, and the needle body of the thickness of needle body 2 also than common sley point is thick, thickness 0.5-0.6mm.

As shown in Figure 4：The utility model macropore sley point 5 and a kind of existing 8 Structure Comparison figure of sley point, this practicality are new Type macropore sley point is increased in pin hole position.

As shown in Figure 5：Fig. 5 is that bayonet covers 7, and for installing sley point, bayonet set 7 is three layers of welding known to the industry Structure, middle layer have guide needle tray 9, have tongue 8, tongue 8 to have certain regime of elastic deformation in needle tray tail portion.

As shown in Fig. 5, Fig. 6, Fig. 7：Sley point 5 is inserted from the guide needle tray of buckle set 7, and bayonet covers tongue 8 to below The distance of plane is slightly smaller than the width at sley point screens notch 3, when sley point is inserted inward, 4 open-top tongue of guiding surface 8, when the screens notch 3 of sley point reaches tongue position, tongue 8 is since pretightning force snaps into screens gap position, to lead Hereafter yarn needle clamping wants the power of bigger sley point could be allowed to move.

Claims (2)

1. a kind of sley point includes：Pin hole（1）, shank（2）, screens notch（3）, guiding surface（4）, it is characterized in that：Pin hole（1） Shape be kidney slot.

2. a kind of sley point as described in claim 1, it is characterized in that：The arc radius R of kidney slot is 0.75-1. 5mm, waist The centre-to-centre spacing d in shape hole is 0.3-1.0mm, shank（2）Thickness be 0.5-0.6mm.
