Description

Compound needle of warp knitting machine

Technical Field

The utility model relates to a tricot machine technical field relates to a tricot machine needle spare, especially a compound needle of tricot machine.

Background

The knitting of the warp knitting machine requires the mutual matching of the knitting parts, and the motion matching of the knitting parts of different types of warp knitting machines is different. To accommodate the need for high speed and high quality knitting, most modern warp knitting machines use compound needles. The compound needle consists of a groove needle and a needle core. The mutual matching movement of the groove needle and the needle core enables the needle opening to be closed or opened, so as to complete the loop forming and the loop releasing of the coil.

As shown in FIGS. 1-2, in the prior art, a grooved needle used in a warp knitting machine has a relief at the back of the needle bar of the grooved needle, a needle groove is formed in the front of the needle bar, the needle groove cut extends downward to the upper part of the transition portion, and a needle core moves in the needle groove. The grooved needle bar is usually longer and softer if the strength is increased by increasing the thickness of the needle bar. When the thickness of the groove needle is too large, the groove needle cannot be used for a warp knitting machine with a high machine number. If the strength is increased by simply shortening the length of the needle bar, the stroke of the needle core is insufficient, and the stroke S1 of the needle core is relatively short, so that the matching range of the grooved needle and the needle core is limited. When the slot needle head is flush with the needle core, the needle core is less in the slot, when the yarn tensions the slot needle hook, the needle bar of the slot needle can be pulled and deflected, and the needle core even breaks away from the needle slot. Causing abrasion and damage of needle parts, affecting the quality of fabrics and causing defects such as uneven cloth surfaces, uneven density, broken holes and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, the utility model provides a compound needle of tricot machine has processing convenience, and needle bar rigidity, intensity are high, and the nook closing member stroke is long relatively, the nook closing member tin billet not with the technical characterstic that the groove needle interfered. The needle bar of the grooved needle of the utility model is not easy to be deviated or deformed, and the needle core is kept in the needle groove. Reduces the abrasion and damage of the needle parts, prolongs the service life of the needle parts and is beneficial to improving the production efficiency. Meanwhile, the evenness and the uniformity of the cloth cover are improved, the defect rate is reduced, and the grey cloth quality is improved.

In order to solve the problem that the above-mentioned technical background exists, the utility model discloses a technical scheme be: a compound needle of a warp knitting machine comprises a groove needle and a needle core. The grooved needle comprises a needle head, a needle rod and a stitch. The needle core comprises a head part, a transition part and a root part, and a plurality of needle cores are cast in a group of needle core tin blocks with certain sizes. The grooved needle and the needle core move in a matching way. The needle bar is characterized in that the back of the grooved needle bar is linear, and the turning part of the grooved needle bar is a large arc transition part. The length of the needle rod is shortened, and the rigidity is increased. The back part is cancelled and abdomens the needle bar, thereby increasing the strength of the needle bar. The grooved needle is closer to the knocking-over piece when descending, so that the grooved needle can ascend and descend more stably in the looping circulation. When the yarn tightens the grooved needle hook, the grooved needle is not easy to be pulled to deviate or deform, so that the needle core effectively closes the needle opening, looping and knocking-off are smoothly completed, and the improvement of the evenness and uniformity of the cloth surface is facilitated. Effectively reduce the needle piece loss, prolong the service life of the needle piece and be beneficial to the improvement of the production efficiency.

As an improvement, a needle groove is formed in the front side of the grooved needle rod, and a needle groove cut extends downwards to the tail of the large-arc transition part. The relative stroke of the needle core is increased, and when the groove needle head is flush with the needle core, the part of the needle core in the needle groove is more and is not easy to separate from the needle groove. The method is favorable for the smooth operation of looping circulation and improves the grey cloth quality.

As an improvement, the inner arc of the needle core transition part is an acute angle, and a needle core tin block does not interfere with a grooved needle in a warp knitting looping cycle, so that the abrasion to the grooved needle is reduced, and the service life of a needle piece is prolonged.

The utility model has the advantages that:

1. the back of the grooved needle rod is designed into a linear type, and the turning part of the grooved needle rod is a large arc transition part. The length of the needle bar is shortened, and the rigidity is increased. The back part is cancelled, the needle bar becomes thick, and the strength of the needle bar is increased. The groove needle is closer to the knocking-over piece when descending, and the groove needle is more stable in ascending and descending in the looping circulation. When the yarn tightens the grooved needle hook, the grooved needle is not easy to be pulled to deviate or deform, so that the needle core effectively closes the needle opening, and looping off are smoothly completed. The evenness and evenness of the cloth surface are improved, the needle loss is effectively reduced, the production cost is saved, and the production efficiency is improved.

2. The needle groove notch extends downwards to the tail part of the large-arc transition part, the relative stroke of the needle core is increased, when the groove needle head is flush with the needle core, the needle core is more in the needle groove part and is not easy to break away from the needle groove, the looping circulation is favorably carried out smoothly, and the grey cloth quality is improved.

3. The inner arc of the transition part of the needle core is acute angle, and when the needle core descends to the lowest position, the tin block of the needle core does not interfere with the grooved needle. Reduce the abrasion to the grooved needle and prolong the service life of the needle piece.

4. The improvement of the utility model makes the needle processing and production operation more simple and convenient.
