Knitting needle

Abstract

The invention relates to a knitting needle. The knitting needle comprises a needle hook, a needle latch, a needle handle provided with a first loop transfer part and a reed, wherein the reed is provided with a second loop transfer part, the front part of the reed is bent outwards to form a bulge, and the rear part of the reed is connected with the bottom surface of a groove to form a connecting end; and the deformation surface and the bulge are not exposed out of the groove, or the part, exposed out of the groove, is elastically pressed in the groove by a needle groove, or the part, exposed out of the groove, is located in a concave groove formed in the corresponding side of the needle groove. The deformation surface generates elastic deformation to drive the bulge to expand outwards, so that coils hung on the first loop transfer part and the second loop transfer part are expanded, and the deformation surface and the bulge sink into the groove in a natural state or when being pressed by the needle groove, so that the overall width of the knitting needle is small, more knitting needles can be arranged on a needle plate in the transverse direction to adapt to the high-density knitting of a transverse knitting machine, and the parts, exposed out of the groove, of the deformation surface and the bulge can further be placed in the concave groove formed in the corresponding side of the needle groove to adapt to different knitting requirements.

Description

Technical field: [0001] The present invention relates to knitting needles for knitting, and more particularly to knitting needles for flat knitting machines. Background technique: [0002] The flat knitting machine is symmetrically provided with a front needle bed and a rear needle bed, and the front and rear needle beds are respectively provided with one-to-one corresponding needle grooves, and knitting needles are respectively arranged in the needle grooves. Such as Figure 43 , 44 , the knitting needle generally has a needle hook A1, a needle latch A2 and a needle handle A3. The needle latch A2 is arranged on the rear side of the needle hook A1, and the needle hook A1 can be closed by turning. The rod A31 and the needle body A32 are composed. The needle body A32 protrudes upward from the rear side of the needle shaft along the width direction and is wider than the width of the needle shaft. A4. [0003] When doing general knitting, the knitting needle moves up and down...

Problems solved by technology

[0006] When performing transfer knitting, the stitches on the knitting needles slide onto the top end surface A51a of the protrusion A51 through the raised front slope A51b and correspond to the positions of the first transfer part and the second transfer part, and are expanded. , so the protrusion must be higher than the side of the corresponding needle handle. At the same time, the knitting needle corresponding to the knitting needle is inserted into the hook insertion groove A511 from the bottom of the hook insertion groove, and inserted into the loop hanging on the needle During this period, the knitting needles on the above-mentioned rear needle bed will move in the length direction relative to the knitting needles on the front needle bed, so the needle hook insertion slot needs to be long enough to provide a movement space for the appropriate length; The coil of the circle is more easily slid from the front side inclined surface A51b to the raised top surface A51a to realize the expansion of the circle, and the slope of the front side inclined surface should be as gentle as possible, that is, the slope is small; The side inclined surface A51c slides onto the top surface A51a, and the slope of the rear side inclined surface A51c should be as small as possible, so that the raised part will be too long, the rigidity will be poor, and it will be easily deformed when the coil is pulled diagonally or horizontally, which is not conducive to weaving. Needle insertion, thereby reducing the reliability of insertion; if the slope of the rear side is large, the coil is not easy to slide from the raised rear side slope to the raised top surface, and the coil will be "scratched"; in order to improve the reed Rigidity, to avoid the phenomenon of "scratching thread", it is necessary to make the raised part high enough, and when the loop is transferred to the knitting, the loop returns to the root of the needle bar and hangs on the raised section, the loop is stretched relatively large, and cannot adapt to the high density of weave

[0007] The above-mentioned knitting needles with reeds in the prior art also have the following problem: the protrusion on the reed is always higher than the corresponding side of the needle, and the needle takes up a lot of space, and needs to be processed on the steel sheet forming the groove wall of the needle groove. Matching grooves are provided to allow the protrusions to be embedded in the grooves, which makes the process of steel sheet processing and needle plate installation complicated, and the production efficiency is low, thereby increasing the cost; at the same time, the steel sheets with grooves cannot be made into fine needle pitches. The needle plate cannot adapt to the knitting of finer gauge

[0008] In addition, the existing knitting needles cannot guarantee that the latch receiving the knitting needle can be opened by the lower end of the hook insertion groove or the lower end of the needle handle of the matching knitting needle when the knitting needle is transferred. When the loop coil is opened corresponding to the needle latch of the knitting needle, the front end of the needle latch will often poke into the knitting thread composed of multiple yarns, resulting in the phenomenon of "monofilament", thus causing fabric defects
