Description

Knitting needle in flat knitting machine

Technical Field

The utility model belongs to the technical field of knitting machinery, in particular to knitting needle in flat knitting machine.

Background

The knitting needle is an important component in a knitting system of the computerized flat knitting machine, the knitting needle comprises a needle head, a needle body and a needle tail, a needle hook and a needle tongue are arranged on the needle head, a concave surface is arranged on one side of the needle body, and a spring piece is in an arc shape and forms an opening with the needle body, so that the knitting needle at the opposite position can be guided to reach a needle turning position, and the needle turning action is finished. The needle body is divided into a front section and a rear section, the width of the rear section of the needle body is larger than that of the front section of the needle body, a coil transfer part is formed at the joint of the front section of the needle body and the rear section of the needle body, the coil transfer part is positioned at the middle section of the hole, and when a needle is turned, the coil is positioned at the coil transfer part, so that a needle receiving knitting needle can smoothly pass through the needle turning coil.

In order to realize the functions of knitting, needle sending, needle retracting and forming and the like of various double-sided fabrics, a plurality of existing flat knitting machines adopt a multi-needle bed structure. The upper needle bed and the lower needle bed in the multi-needle bed structure are both provided with knitting needles, but the installation angle of the upper needle bed is not as steep as that of the lower needle bed, so that the knitting needles arranged on the upper needle bed are relatively flat, and the upper turning knitting needles travel along an M-shaped needle travel track, so that when the turning knitting needles of the upper needle bed move upwards, the coils are still positioned at the coil transfer part, and because the side edges of the front section of the needle body of the coil transfer part are flush, when the turning knitting needles move downwards, the coils can not synchronously move downwards along with the turning knitting needles, so that the coils are separated from the coil transfer part and move to the front section of the needle body, and the needle receiving knitting needles can not smoothly pass through the turning coils to form missed stitches. Meanwhile, when the stitches on the knitting needle of the lower needle bed are subjected to a small pulling force, the stitches cannot slide down to the stitch transfer portion due to the small pulling force when the knitting needle of the lower needle bed is withdrawn, and the stitches are not passed through the stitch transfer portion during the stitch transfer, so that missed stitches are formed.

Disclosure of Invention

The utility model aims at solving the above problem and providing a knitting needle which has simple structure and can ensure the success rate of needle receiving and needle turning.

Therefore, the technical scheme of the utility model is that: a knitting needle in a flat knitting machine comprises a needle head, a needle body and a needle tail, wherein a needle hook and a needle latch are arranged on the needle head and are rotationally connected, a spring piece is arranged on the side surface of the needle body and is in an arc shape, a concave surface is arranged on one side of the needle body, which faces the spring piece, the middle part of the spring piece is arched, and a hole is formed between the middle part of the spring piece and the concave surface of the needle body; the bending direction of the needle hook is set as the left side of the knitting needle, and the side of the needle hook, which is deviated from the knitting needle, is the right side of the knitting needle;

the method is characterized in that: the needle body is divided into a front section and a rear section, the width of the rear section of the needle body is larger than that of the front section of the needle body, the right side of the front section of the needle body is flush with the right side of the rear section of the needle body, and a coil transfer part is formed at the joint of the left side of the front section of the needle body and the left side of the rear section of the needle body; the coil transfer part is provided with a first notch which is concave towards the right side of the knitting needle, the spring piece is provided with a second notch, and the second notch corresponds to the first notch in position.

Preferably, the first notch is in transitional connection with the left side of the front section of the needle body through a first inclined plane, and the second notch is in transitional connection with the side edge of the spring piece through a second inclined plane.

The utility model discloses all increased the notch on the needle body of knitting needle and spring plate, when turning over knitting needle and go upward when the needle position that turns over, the coil falls on the first notch department of coil handing-over portion, when turning over knitting needle and retreating, the coil still can steadily keep in first notch department, does benefit to the needle that connects smoothly that the knitting needle connects the needle. The side of the first notch and the side of the second notch facing the needle head are both inclined planes, so that the stress on the coil is prevented from suddenly changing and excessively rubbing, and the coil is stably turned over to a needle connecting knitting needle.

The utility model discloses all increased the notch on the needle body of knitting needle and spring plate, the coil that makes thicker or multifilament yarn produce also can keep in coil hands over the position, has not only guaranteed that the knitting needle of flat position turns over the needle smoothly, has also guaranteed that little pulling force's coil turns over the needle smoothly.
