Description

Knitting needle of computer flat knitting machine

Technical Field

The utility model relates to the field of textiles, in particular to a knitting needle of a computerized flat knitting machine.

Background

The computerized flat knitting machine generally has two needle beds, one needle bed near the knitter is a front needle bed, the other needle bed is a back needle bed, knitting needles are arranged on the needle beds on the two sides, and when a machine head reciprocates on a guide rail of the needle beds, the knitting needles do up-and-down motion in needle grooves of the needle beds under the action of a cam device on the machine head, so that yarns are looped and mutually sleeved in a series to be knitted into fabrics.

The knitting needle of the flat knitting machine disclosed in the grant publication No. CN 202766763U comprises a needle head and a needle body, wherein the needle head comprises a needle hook and a needle tongue, the needle body is provided with a spring piece, the spring piece and the needle body form an opening, a step surface is arranged at the joint of the needle head and the needle body, and the opening formed by the spring piece and the needle body can guide the knitting needle at the opposite position to reach a needle overturning position to complete the action of needle overturning (transferring a coil on one needle bed to the knitting needle on the other needle bed). During the needle turning process, a coil is positioned on the step surface of a knitting needle on one side, when a needle head (a hook and a latch) of the knitting needle on the other side moves to the coil through an opening, the coil enters between the hook and the latch, the latch is opened by the coil to enter the hook along with the continuous rising of the knitting needle, and the latch is attached to the knitting needle on the other side along with the movement of the knitting needle, so that the needle turning is completed.

However, the gap between the hook and the latch is very small, and to achieve the opening of the loop, the needle position must be accurately controlled, otherwise the loop cannot be transferred to the hook of the needle on the other side or the monofilament phenomenon (the insertion of the latch of the joining needle into the loop causes the partial loop not to be completely transferred to the joining hook) occurs. Meanwhile, the relative accurate position (adjusting and turning needle position) of the knitting needles on the two sides is controlled, and the requirements on parts for driving the knitting needles and adjusting personnel are high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a knitting needle of a computerized flat knitting machine, which can open a needle latch in advance in the process of transferring and turning needles, effectively prevent missed stitches, and improve the accuracy of turning needles, the quality of fabrics and the production efficiency. Meanwhile, the requirements on parts for driving the knitting needle and personnel for adjusting the knitting needle are also reduced.

In order to achieve the technical purpose, the technical scheme of the utility model is as follows:

the knitting needle of the computerized flat knitting machine comprises a needle body, wherein the needle body comprises an upper needle body and a lower needle body, the width of the upper needle body is smaller than that of the lower needle body, so that a step surface is arranged at the joint of the upper needle body and the lower needle body, a needle hook and a needle latch are arranged at the head end of the upper needle body, and the needle latch is rotatably connected with the needle hook; the needle body wide side is fixedly provided with an arched reed, a needle penetrating hole is formed between the arched reed and the needle body, a bulge is arranged on the arched reed, the bulge enables the needle penetrating hole to be divided into an upper needle penetrating hole and a lower needle penetrating hole, and the step surface is located on one side of the lower needle penetrating hole.

When the needle is turned over, the hook and the latch of the needle of one side needle bed penetrate into the upper needle-penetrating hole of the needle of the other side needle bed, and the hook is extruded to pass through the bulge along with the movement of the needle; because the bow-shaped spring leaf has elasticity, when the needle hook passes through the bulge, the bow-shaped spring leaf restores the original state; with the continuous movement of the knitting needle, the bulge which returns to the original state enables the latch to rotate, and the latch is opened (the distance between the end part of the latch and the hook is increased); along with the continuous movement of the knitting needle, the needle hook for opening the latch easily passes through the coil on the step surface, and the coil is accurately connected into the needle hook, so that the coil is transferred, the needle turning accuracy is improved, and the missing of the needle is avoided.

The upper needle body is provided with a needle latch groove, and the needle latch is connected in the needle latch groove through a needle latch pin. The latch can rotate around the latch pin to open or close the hook.

The wide side of the needle body is provided with a first groove, and the first groove and the bow-shaped spring leaf form a needle penetrating hole. The first groove is used for reducing the thickness of the knitting needle and ensuring that the end part of the knitting needle can penetrate into the needle penetrating hole.

The needle body is provided with a second groove and a third groove, the head end of the bow-shaped reed is arranged in the second groove, and the tail end of the bow-shaped reed is fixedly arranged in the third groove. The second groove and the third groove enable two ends of the arched reed to be embedded into the needle body, and the coil can be prevented from being hooked by the reed.

And the needle body is provided with an inclined plane at the needle inserting side of the needle penetrating hole. The bevel may guide the needle through the needle penetration hole.

The tail end of the lower needle body is provided with a needle tail, and a frame-shaped gap is formed at the joint of the needle tail and the lower needle body. The connecting surface of the frame-shaped gap and the lower needle body is a cambered surface bent towards the needle body. The frame-shaped notch is used for matching the long needle, so that the knitting needle is pushed (pulled back) to a corresponding position through the long needle. The structural characteristic that the opening of the frame-shaped gap is small and the bottom is large can ensure that the long needle always forms a matching relation with the knitting needle when a certain amount of vertical jumping is generated.

The utility model divides the needle-threading hole into an upper needle-threading hole and a lower needle-threading hole through the bulge, can open the latch in advance, smoothly completes the needle turning action, effectively prevents missing needles, and improves the needle turning accuracy, the fabric quality and the production efficiency. Meanwhile, the relative accurate positions of the knitting needles on the two sides are not required to be accurately adjusted, and the requirements on parts of the driving knitting needles and machine adjusting personnel are reduced.
