Scissors clamp device in flat knitting machine

Abstract

The invention discloses a scissors clamp device in a flat knitting machine. A small needle plate assembly is fixed on a machine frame and an extension part of a needle plate and provided with a small needle plate and a hooked needle, and a yarn clamping block assembly is provided with a yarn clamping block and an elastic device. Selection needles are driven to rise through a machine head triangle, the hooked needle is pushed along a groove of the small needle plate, so that a hooked needle butt is exposed of the upper surface of the small needle plate, enters a triangular track to be pushed to a yarn hooking position and hooks yarn, and then the hooked needle is pushed to an initial position through the triangular track. When the hooked needle passes through a yarn cutting block, the sharp edge of the yarn cutting block is utilized to cut off the yarn, and simultaneously the yarn is held by close fit between a rubber block and the hooked needle. The groove of the small needle plate can guarantee that after the hooked needle and the selection needles return, the hooked needle butt and selection needle butts are located below the surface of the small needle plate. The elastic device of the yarn clamping block assembly enables the yarn cutting block to be fixed in a long hole of a spring fixing seat through the hooked needle, and a spring guarantees elastic force always existing between the yarn cutting block and the hooked needle.

Description

technical field [0001] The invention belongs to the technical field of knitting machines, in particular to a scissors clip device in a flat knitting machine. Background technique [0002] Flat knitting machines all have scissors device at present, complete the function of clamping thread and cutting yarn by scissors device. In the prior art, two scissors are used on the left and right sides of the flat knitting machine, but this structure will cause yarn clamping when weaving patterns that require multi-color yarns, and the yarn will be damaged when the yarn is clamped . Usually we can change these phenomena by adjusting the pattern process, but this method will increase the number of running lines, thereby increasing man-hours and reducing work efficiency. Contents of the invention [0003] The content of the present invention is to solve the above problems and provide a scissors clip device in a flat knitting machine that can cut and clip yarns when the patterns ar...
