Color change head

Abstract

The invention relates to the technical field of knitting machines, in particular to a color change head. The color change head comprises a shell, control mechanisms, a linkage mechanism, an action mechanism and a first elastic assembly, wherein the control mechanism comprises a plurality of color selection plates which are arranged at certain intervals; each color selection plate comprises a first connecting rod and a swing rod; one ends of the swing rods are pivoted to the shell, and the other ends of the swing rods can swing freely; the upper edges of the swing rods are provided with first pressing convex parts; the middle parts of the first connecting rods are pivoted to the shell; the upper edges of one ends of the first connecting rods are provided with second convex parts which are pressed against the lower edges of the swing rods; the first elastic assembly acts on the first connecting rods to supply resilience force for pressing the first convex parts to the lower edges of the swing rods; between different control mechanisms, the positions of the second convex parts are inconsistent; when the first convex parts are closer to a first revolving shaft, the second convex parts are farther away from a second revolving shaft. By adopting the structure, a needle selection action can be triggered when the pressing travel of each first convex part is consistent, color selection balance is realized, the pressing actions of the first convex parts are flexible, and the resilience speed is high.

Description

technical field [0001] The invention relates to the technical field of knitting machines, in particular to a color changing head. Background technique [0002] When the knitting machine is weaving fabrics, if it is not necessary to weave patterns of different colors, a color-changing head will be installed at the yarn feeding port of the knitting machine. During the weaving process, the color-changing head will timely bring the colored yarn Go to the yarn feeding port to let the knitting needle hook the yarn, let the colored yarns be woven together, so that the fabric after the first pass has different color pattern effects. [0003] In the existing technology, due to its unreasonable design structure, when the first protrusion used for needle selection triggers different first protrusions, the pressing strokes are inconsistent, making it difficult to adjust other equipment that cooperates with it. If the stroke is too large, the equipment will be damaged, but if the stroke...

Problems solved by technology

[0003] In the existing technology, due to its unreasonable design structure, when the first protrusion used for needle selection triggers different first protrusions, the pressing strokes are inconsistent, making it difficult to adjust other equipment that cooperates with it. If the stroke is too large, the equipment will be damaged, but if the stroke is too small, the needle selection will not be triggered.
