The needle and the horizontal knitting needle of the horizontal needle group 10B interweave the yarn fed by the yarn feeding device.

Please refer to FIG. 2, which is an exploded schematic view of a rotating cylinder of a general rib knitting machine. The vertical needle group 10A of the rotary cylinder 1 is vertically arranged in a ring shape by a plurality of vertical knitting needles 4, and a driving rod 41 is usually provided to drive the vertical knitting needles 4 to move up and down. The horizontal needle group 10B of the rotating cylinder 1 is arranged horizontally and radiated by a plurality of horizontal knitting needles 3 in an annular manner above. The horizontal knitting needles 3 are arranged in a radial groove of a horizontal dial 20, so they can be stably moved in the groove of the horizontal dial 20. The horizontal dial 20 and the lower vertical needle group 10A rotate together to drive the horizontal knitting needles 3 to rotate, the upper horizontal needle track base 21 is fixed, the horizontal needle track base 21 is provided with a track, and the horizontal knitting needle 3 is along the track Needle out or retract.

There are different forms of the track provided under the horizontal needle track base 21, and a ring-shaped metal (not shown) with a curved path is used as a track for the horizontal needle 3 to exit and retract the needle.

Please refer to FIG. 3 and FIG. 4, FIG. 3 is a perspective view of the horizontal needle track base of the conventional rib knitting machine with four sets of first track groups, and FIG. 4 is a single group first track of the horizontal needle track base of the conventional rib knitting machines. Set of movement diagrams. In order to make the needle outstroke of the horizontal knitting needle 3 more fine-tuned to produce more interwoven changes, the horizontal needle track base 21 is below (for ease of illustration, the horizontal needle track base 21 in the drawings are all turned over (Upwards) at least one first track group that can change the stroke of the horizontal knitting needle 3 out 5. In the example shown in FIG. 3, four sets of first track groups 5 are provided, and for ease of illustration, FIG. 4 only reserves one set of first track groups 5.

The first track group 5 includes a first guide track 51, an auxiliary track 52, a divided track group 53 and a first narrowing track 54; the divided track group 53 further includes a lower track 531 and an upper track 532. The lower rail 531 and the upper rail 532 are overlapped. The upper rail 532 can adjust the angle relative to the lower rail 531, so that the effect of the rail surface (not shown, which is an outwardly curved surface in the figure) can be different.

The lower rail 531 can also be provided with an arc groove (not marked), and the upper rail 532 can be provided with a driving rod (not marked) which is controlled by an external motion mechanism through the arc groove. During the interweaving process, a computer program passes through a motor or solenoid valve and other power components Pull to fine-tune.

In order to generate different motion paths corresponding to the lower rail 531 and the upper rail 532, the horizontal knitting needle 3 has two types of long-legged needles 31 and short-legged needles 32. A plurality of horizontal knitting needles 3 are radially arranged. For convenience of description, only one long-legged needle 31 and one short-legged needle 32 are shown in the drawing.

The basic structure of the long leg knitting needle 31 and the short leg knitting needle 32 are the same, except that the long leg 311 of the long leg knitting needle 31 is shorter than the short leg 321 of the long leg knitting needle 32.
