Flat knitting machine two-stage stitch controlling device and flat knitting machine

Abstract

The invention discloses a flat knitting machine two-stage stitch controlling device and a flat knitting machine and belongs to the field of flat knitting machines. The flat knitting machine two-stagestitch controlling device comprises at least one group of stitch cams and driving mechanisms corresponding to the group of stitch cams; the group of stitch cams are composed of an upper group of stitch cams and a lower group of stitch cams, the upper group of stitch cams are composed of an upper left stitch cam and an upper right stitch cam, and the lower group of stitch cams are composed of a lower left stitch cam and a lower right stitch cam; the driving mechanisms comprises a first driving mechanism and a second driving mechanism. The flat knitting machine two-stage stitch controlling device replaces a vertical double-layer overlapped arrangement manner with a horizontal arrangement manner with the upper and lower groups of stitch cams, thereby effectively enlarging the contact area between every stitch cam and butts of knitting needles, reducing wearing of the needle butts, avoiding releasing of the needle butts, and further reasonably increasing sinking depth as well as effectively improving the operation stability of the knitting needles. Driven by the two driving mechanisms separately, the flat knitting machine two-stage stitch controlling device can simplify the structure and meanwhile effectively enlarge the stitch adjusting range.

Description

technical field [0001] The invention relates to the technical field of flat knitting machines, in particular to a two-stage stitch control device for a flat knitting machine. In addition, the invention also relates to a flat knitting machine using the two-stage stitch control device. Background technique [0002] The working principle of the existing flat knitting machine is generally to make the yarn complete the actions of lapping, closing, looping, bending, stripping and looping through the regular lifting movement of the knitting needles to weave the yarn into a braided fabric. During the rising process of the knitting needle, the coil gradually withdraws from the needle hook and opens the needle latch, which hangs on the needle bar. When the knitting needle is lowered, the needle hook catches the yarn of the new pad and pulls it to form a new loop. At the same time, the original loop breaks away from the needle hook, and the new loop is connected in series with the orig...

Problems solved by technology

In addition, since this structure requires three motors to drive, the cost is high, the structure is complicated, and the consistency of each motor is poor, which cannot meet the driving requirements well.
