Description

Technical Field

[0001] The utility model relates to the technical field of computer flat knitting machines, in particular to a sinker base assembly structure of a computer flat knitting machine. Background Art

[0002] The existing computerized flat knitting machine has a large distance between the knockout angle of the knockout tooth plate and the position where the yarn is placed at the front end of the needle groove bottom of the needle bed. In particular, the yarn blocking tube mouth steel wire axially penetrates through the small holes slightly larger than the outer diameter of the steel wire of 0.05-0.10 on hundreds or even thousands of knockout tooth plates with a thickness of 0.20-1.00, otherwise it cannot pass through. The slender 0.50-0.70 (depending on the needle spacing, the thickness varies) steel wire is completely suspended in the small holes of the knockout tooth plate without a radial "backbone" for positioning, that is, it does not have a front needle channel. When the knitting needle goes up to the knitting height or the loop transfer height, the needle hook is "far" from the front end of the needle plate when the knitting needle is hanging the thread. In order to prevent The "distance" for stopping the knitting needles from coming out of the needle is far, and the left and right shaking must be minimized to affect normal knitting. A sinker that swings up and down is used as a "backer", but it will rub against the needle. When the sinker is withdrawn under the action of the triangle, the knitting needle loses its "backer". In addition, when the machine head works back and forth, the tension of the yarn causes the exposed part of the unlooping tooth piece to shake left and right. In view of this situation, the knitting speed is reduced when processing single-needle and multi-needle fabrics with complex patterns or shifting structures. The existing three-piece structure of the inlaid tooth sinker can only choose gap matching due to the combined thickness of the three pieces and the slot assembly. Because the sinker must be flexible, it is very easy to cause fine path needles of the fabric in fine-gauge machines, resulting in reduced fabric quality. Utility Model Content
