Technical Field

The invention relates to the technical field of knitting, in particular to a self-adaptive adjustment method for the density of a flat knitting machine.

Background

At present, the production mode of woolen sweaters is mainly batch production, each flat knitting machine only produces a single cloth piece, and the parameters of the flat knitting machines need to be readjusted by replacing cloth piece files. Adjusting the parameters each time wastes time and woollen, resulting in waste. However, this waste has a negligible impact on the cost of mass production and a significant impact on the cost of customized mass production.

In the customized production process, the flat knitting machine is ensured to be in a continuous knitting state as much as possible, the machine is stopped as little as possible, and the yield is improved. However, in the customized production process, the change of the same style size and the change of the color of the wool have certain influence on the density of the finished product, so that the flat knitting machine cannot continuously knit; and factors influencing the cloth piece density include the mesh motor position, the roller tension, the side line frame tension, the yarn storage device output tension, the yarn component, the new gram position and the like, wherein the mesh motor position has the largest influence on the cloth piece density.
