How to repair and maintain the knitting needles of a large circular knitting machine

Flower needle repair: The amount of needle pressed into the needle disc is determined by whether the old coil can be detached from the needle disc (based on the lowest point of the pressed needle). When adjusting the press-in amount of the needle on the needle tray, it is necessary to combine it with the press-in amount of the needle in the syringe. When the variation in the tension of the bent yarn is not significant, the needle triangle of the needle disk should be pressed in by 2 small grids, and the needle triangle of the needle cylinder should be pressed in by 1 small grid to ensure the supply of yarn during the spinning process. Poor needle pressing can cause small holes: In a double-sided machine (or rib machine), if the needle pressing in the triangular part of one of the needle discs is slightly too large, when the strength of the yarn is relatively weak during yarn separation, it is easy for one or two longitudinal or 3-7 horizontal coils to fall off, resembling small missed needles (which only appear at 90-150 revolutions). When this situation occurs with the double-sided machine, it is necessary to carefully check the needle pressing condition of the needle reel and make slight adjustments. Oil needle: If the needle grooves A and B are clogged with oil droplets (such as when the machine has been in operation for a long time), when the oil volume increases, it will cause the oil droplets to be soaked in oil, which is difficult to dry in a short time. In addition, the needle moves back and forth and is repeatedly soaked in oil, thus forming an oil needle.
