Fine needle circular knitting machine

The present invention relates to a circular knitting machine, and more particularly to a fine needle circular knitting machine.

The conventional circular knitting machine mainly comprises a circular syringe provided for a plurality of vertical knitting needles, and a ring-shaped Sike holder disposed on a circumference of the circular cylinder, wherein the annular Sike holder is disposed on a plurality of pockets relative to The Schenker slices in the direction of the circular syringes, the knitting needles and the Schenck sheets are respectively moved by the corresponding driving mountain angles, and the knitting threads are interlaced.

In recent years, in order to further improve the quality and feel of the fabric, 遂 developed a fine-pitch circular knitting machine with a high number of knitting needles, as in WO2012055591, discloses a knitting machine with a high lattice distance, including a needle holder. A plurality of needles are supported which are actuated to perform an alternating movement along their axes and means for guiding the needles to the needle holder. Each needle can be actuated to perform an alternate movement along its axis relative to the needle holder, and by one of the alternating movements, the needle can be withdrawn from one end of the needle holder along with a portion of the needle tip and the needle handle So that the previously formed interlaced loop falls onto the needle handle and/or picks up one or more strands of yarn that are applied to the yarn feed or yarn guide of the machine. And by retracting the movement of the one of the alternating movements, the needle is retracted into the end of the needle holder together with the needle tip to form a new interlacing loop, thereby performing the unwinding of the previously formed interlacing loop to produce the interlacing The guiding member includes a passage for forming an interlacing, the passage being defined adjacent the end of the needle holder, and a sliding passage defined on the needle holder spaced from the end of the needle holder In one of the regions, each of the channels for forming the interlace can be engaged by a needle and with its inlet leading to the outside of the needle holder defining a supporting contact area for interlacing during the retracting motion of the needle, The number of such sliding channels is less than the number of such channels used to form the interlacing.

In the conventional circular knitting machine, in order to enable the Shenke sheet to stably perform horizontal reciprocating motion, in addition to the plurality of receiving slots provided for the Schenker body on the ring-shaped sleeve, the circular cylinder is also A positioning groove corresponding to the nose extending from the upper portion of the singapore sheet to the upper knitting position is opened. For the circular knitting machine with the high number of knitting needles mentioned above, the distance between the knitting needles or the Shenke sheet, or the thickness of the knitting needle and the Shenke sheet, is bound to decrease as the number of knitting needles increases, so that the circle The distance between the positioning grooves on the shaped syringe for inserting the Shenke piece needs to be shortened as well. Therefore, in order to cope with the high number of knitting needles, it is quite difficult to form a large number of narrow-distance positioning grooves on a metal circular cylinder, and the production yield is rather low. Furthermore, when the Schenck sheet is in contact with the inner wall of the positioning groove due to slight tolerances, the thinned Schenk sheet is easily damaged and deformed due to high temperature friction during the knitting operation of the circular knitting machine, and the operator Frequent replacement of damaged Schenk sheets will cost a lot of time and refueling costs.

On the other hand, when assembling a thinned Schenker sheet, it is necessary to accurately align a large number of Schenk sheets with the positioning grooves of the circular syringe one by one, which takes a considerable amount of time, and if there is an error in installation, It takes extra time to reinstall, which is not conducive to the production efficiency of the overall high needle count circular knitting machine.
