Abstract

The utility model relates to a knitting needle of knitting machine. the technical proposal is that: the utility model consists of a pin hook, a needle latch, a needle bar, a butt and a needle tail; wherein, the needle latch sways to open or close the pin hook with the pin joint shaft of the needle bar as the pivot. Compared with prior art, the transitional end of the pin hook and the needle bar are provided with a bevel, thus, the round value of the medial margin of the pin hook is reduced, the clearance within which the double warps rolls about is reduced so as to maintain the front and back positions of the double warp. Thus, the utility model has the advantages of preventing the double warp from twisting inside the pin hook.

Description

A kind of needle of needleloom

Technical field

The utility model relates to a kind of needle of needleloom.

Background technology

Existing known needle of needleloom is made up of pinhock, needle latch, shank, pin heel and backshank, and needle latch is that pinhock is opened or sealed to axis swing with the drive-connecting shaft of itself and shank, cooperates the driving of other associated mechanisms, and knitting needle is weaved cotton cloth.

In knitting technology, usually simultaneously to knitting needle supply at least two one threads, so that obtain special effect thus, one of them effect is exactly the plaiting of so-called smooth fabric.In this case, so supply two one threads to knitting needle, the i.e. right side of front and the especially knitwear of an one thread contact pin fabric wherein, and the left side of another one thread contact pin fabric or the knitwear back side can obtain different effects by the different yarn of the different yarn of the different yarn of serviceability such as color or material on the front of knitwear and the back side.Here, such yarn is called as " needle thread ", and it has formed the front, and is become " wire gauze " by its covering and yarn that form the back side.But such title generally is inessential, because this depends on which yarn is on which face of fabric and should be exposed.

The manufacturing of smooth knitwear is to realize like this, promptly at least two one threads are supplied with knitting needle separately, be them according to predetermined space be threaded in the pinhock, should arrange wherein a yarn and as close as possible bill ground another root yarn of layout in as close as possible shank ground, thereby obtain good dividing sinker effect; If handle simultaneously under special circumstances one common flexible as fine yarn as thicker yarn and one, then usually rove near shank and spun yarn supplies yarn near bill ground.

Although it is fairly simple that guide seems, but when making smooth knitwear, always have tired difficult, one of them main cause is exactly that yarn does not always keep it to pass through the special arrangement thread-carrier and definite position when lopping when penetrating pinhock, thereby often be that no destination changes and alternately preposition or rearmounted yarn during plaiting, two yarns can be rolled about in pinhock, make two easy winding disc thighs of yarn, influence is weaved cotton cloth and is made needle latch impaired.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provides a kind of pinhock rational in infrastructure, makes that two yarns are taken their own roads, the needle of needleloom of winding disc resultant yarn thigh not.

The purpose of this utility model is achieved in that by pinhock, needle latch, shank, pin heel and backshank to be formed, needle latch is that pinhock is opened or sealed to axis swing with the drive-connecting shaft of itself and shank, and difference from prior art is: the excessive end at pinhock and shank is provided with an oblique chamfering.

The utility model, the angle value of this oblique chamfering are 20～35 °.

The utility model, because the excessive end at pinhock and shank is provided with an oblique chamfering, the medial margin fillet value of pinhock is dwindled, reduce the gap that two yarns can be rolled about in pinhock, make that two yarns are taken their own roads, tandem position relation remains unchanged, therefore, has the advantage of avoiding two yarn winding disc resultant yarn thighs in pinhock effectively.

Following embodiment accompanying drawings is further described the utility model.

Description of drawings

Fig. 1, Fig. 2, Fig. 3 are respectively the structural representations of the needle of needleloom of existing known pinhock perigon angle structure; Wherein, Fig. 1 is a perspective view, and Fig. 2 is main TV structure schematic diagram, and Fig. 3 is the A place structure for amplifying schematic diagram of Fig. 2;

Fig. 4, Fig. 5, Fig. 6 are respectively the structural representations of an embodiment of the present utility model; Wherein, Fig. 4 is a perspective view, and Fig. 5 is main TV structure schematic diagram, and Fig. 6 is the B place structure for amplifying schematic diagram of Fig. 5.

Among the figure, 1, pinhock, 2, needle latch, 3, shank, 4, the pin heel, 5, backshank, 6, drive-connecting shaft, 7, the excessive end of pinhock and shank, 8, first yarn, 9, second yarn, C, oblique chamfering.

The specific embodiment

With reference to Fig. 4, Fig. 5, Fig. 6, present embodiment is made up of pinhock 1, needle latch 2, shank 3, pin heel 4 and backshank 5, needle latch 2 is that pinhock 1 is opened or sealed to axis swing with the drive-connecting shaft 6 of itself and shank 3, excessive end 7 at pinhock 1 and shank 3 is provided with an oblique chamfering C, and the angle value of this oblique chamfering C is generally 20～35 °.

Use of the present utility model, be used for comparative illustration with making of existing known needle of needleloom, with reference to Fig. 1, Fig. 2, Fig. 3, existing known needle of needleloom, the structure of pinhock 1 is the perigon angle structure, and the medial margin fillet value of pinhock is bigger, and two yarns i.e. first yarn 8, second yarn 9 can be rolled about in pinhock, make two yarns i.e. first yarn 8, second yarn, 9 easy winding disc thighs, influence is weaved cotton cloth and is made needle latch impaired.With reference to Fig. 4, Fig. 5, Fig. 6, because the excessive end 7 at pinhock 1 and shank 3 is provided with an oblique chamfering C, the medial margin fillet value of pinhock 1 is dwindled, reducing two yarns is the gap that first yarn 8, second yarn 9 can be rolled about in pinhock, making two yarns is that first yarn 8, second yarn 9 are taken their own roads, tandem position relation remains unchanged, and avoids two yarn winding disc resultant yarn thighs in pinhock effectively.

Claims
