Abstract

A tongue needle of the weft knitting round knitting machine, one end of the tongue is provided with a needle hook, and the opening end of the needle hook is pivoted with a sheet of needle tongue, the middle of the tail end of the needle hook forms a clamp groove that can accommodate the needle tongue, the groove bottom of the clamp groove forms a blocking part to stop the needle tongue on the outer circumferential edge of the needle hook, the distance between the blocking part and the side edge of the tongue needle is 1.05 mm, the largest distance between the needle tongue and the side edge of the needle hook is 1.26 mm when the needle tongue is covered on the blocking part of the needle hook, because the width is relatively small, the annular circle of the yarn circle is relatively small and the cloth surface knitted is relatively smooth when circle generation effect is generated.

Description

The latch needles of weft knitting circular knitter

Technical field

The utility model is a kind of latch needles of weft-knitted circular knitter, is the parts that belong to Knitting Machinery.

Background technology

As shown in Figure 2, latch needles 30 is to be the necessary member of knitting machine, the stage casing that is provided with hook-shaped pinhock 31 and mobilizable needle latch 32 shanks 300 in the wherein end of shank 300 then is provided with outstanding stitch 33, by the 33 stressed reciprocating motions that make it that lifting or horizontal take place of outstanding stitch, even pinhock 31 cooperate with needle latch 32 produce as Fig. 3 1.-5. shown in eat the knitting effect that yarn is made ring, the ring of making of needle latch 32 act as:

Move 1.: latch needles 30 rises, and old yarn ring a weighs down and opens needle latch 32, and along sliding into needle latch 32 tips under needle latch 32 inboards;

Move 2.: latch needles 30 is of continuing rising, and when arriving peak, old yarn ring a is slipped on the shank 300;

Move 3.: latch needles 30 descends, and old yarn ring a is along sliding on the shank 300; Just at this moment, feed directs into new yarn A before the unlimited pinhock 31;

Move 4.: latch needles 30 continuous falling, old yarn ring a pushes away and closes needle latch 32, and along sliding on needle latch 32 outsides; By on close needle latch 32 and dial in new yarn A within the pinhock 31, for latch needles 30 is left behind;

Action is 5.: latch needles 30 is fallen to minimum point, and old yarn ring a breaks away from syringe needle and enters tissue, and new yarn A Cheng Huan in pinhock has replaced the status of the former yarn ring a that has been friends in the past, has promptly finished this and one has made the ring cycle, has just begun the circulation of another time again in case rise once more.

Above-mentionedly be the latch needles 30 ring effect of making when knitting, yet, the braided fabric that is become generally has surperficial mao mao's sensation, do not require for product, or originally with regard to wanting to cause the clothing that the mao mao feels, this kind fabric quality perhaps proper its branch, but for the designers, it is that designed clothing always wishes to show with suitable cloth, if when the cotton material of the surperficial hairiness feel of wool of this kind is not suitable for its designed clothes, has had a hunch shortcoming more so.

Further probe into present cotton material surface and have the reason that the mao mao feels, be to be due to the shape of pinhock 31 and needle latch 32, see also shown in Figure 4, form in the middle of pinhock 31 terminal one can ccontaining needle latch 32 clip slot 310, clip slot 310 bottom lands on pinhock 31 outer peripheral edges, form one can block needle latch 32 the portion 311 that supports, the portion of supporting 311 is 1.35mm with the side distance L 2 of latch needles 30, when needle latch 32 is covered on pinhock 31 openends, needle latch 32 is 1.55mm with the side ultimate range L1 of pinhock 31, in brief, since between needle latch 32 and the pinhock 31 apart from broad, to such an extent as to the yarn ring that is woven into footpath pine more greatly and, and formation mao mao's sensation.

So,, therefore, necessity of improvement is arranged at the pinhock 31 and the shape of needle latch 32 of latch needles 30 because the shape of latch needles 30 influences the texture of fabric.

The utility model content

In order to improve above-mentioned disappearance, of the present utility model main day being provides a kind of can make that the cloth surface is comparatively level and smooth, the latch needles of consolidation.

Based on above-mentioned purpose, major technique means of the present utility model are to provide a kind of latch needles of weft-knitted circular knitter, a wherein end of latch needles is provided with pinhock, form in the middle of pinhock terminal one can ccontaining needle latch clip slot, the clip slot bottom land on the pinhock outer peripheral edges, form one can the block needle latch the portion that supports, described side distance of supporting portion and latch needles is 1.05mm, and needle latch is covered on pinhock when portion, and the side ultimate range of needle latch and pinhock is 1.26mm.

Implement after the above-mentioned technological means, the yarn ring that is made into footpath is less, than consolidation, so can have the quality of weaving cotton cloth of smooth surface.

Description of drawings

Fig. 1 is a local enlarged diagram of the present utility model;

Fig. 2 is the floor map of existing latch needles;

Fig. 2 implements to make the action schematic diagram that ring is done the time spent for existing latch needles;

Fig. 4 is the local enlarged diagram of existing latch needles.

The specific embodiment

See also shown in Figure 1, latch needles 10 its ring effects of making that produced of weft-knitted circular knitter that the utility model provides are the same with existing product, so no longer superfluous, and in order to improve the aforementioned disappearance of commonly using latch needles, the utility model is improved at the pinhock 11 and the needle latch 12 of latch needles 10 especially.

Described pinhock 11 is towards an end opening, form in the middle of pinhock 11 terminal one can ccontaining needle latch 12 clip slot 110, clip slot 110 bottom lands on pinhock 11 outer peripheral edges, form one can block needle latch 2 the portion 111 that supports, the portion of supporting 111 is 1.05mm with the side distance H 2 of latch needles 10, when needle latch 12 is covered on pinhock 11 openends, needle latch 12 is 1.26mm with the side ultimate range H1 of pinhock 11, in brief, because the ultimate range between needle latch 12 and the pinhock 11 only has 1.26mm, its width is about 19% less than aforementioned existing latch needles, and therefore, the yarn ring ring that is made into is less, than consolidation, and can obtain more level and smooth cloth surface, improve existing cloth surface mao mao's sensation.

From the above, latch needles design of the present utility model can obtain the surface of weaving cotton cloth of level and smooth and consolidation, to meet designer and consumer demand to clothing texture, the cloth texture that it was made into is that existing latch needles fails to reach, and its structure does not see existing product and open source information again, is that mere formality is filed an application in accordance with the law.

Claims

1, a kind of latch needles of weft-knitted circular knitter, a wherein end of latch needles is provided with pinhock and is pivoted a needle latch that can be covered on the pinhock openend, form in the middle of pinhock terminal one can ccontaining needle latch clip slot, the clip slot bottom land on the pinhock outer peripheral edges, form one can the block needle latch the portion that supports, it is characterized in that: described side distance of supporting portion and latch needles is 1.05mm, needle latch is covered on pinhock when portion, and the side ultimate range of needle latch and pinhock is 1.26mm.
