Abstract

The invention provides a method and a device for selecting a magnetic levitation driven needle. A pattern bit, a needle jack, a needle and a triangle in a traditional weaving structure are integrated together. In an action process, an impact friction and a lateral force do not exist between the needle and a needle shell base, thereby realizing a high-speed and magnetic levitation controlled needle three-position motion. The device for selecting the magnetic levitation driven needle has the advantages that the structure is simple, the cost is low, the service life is long, and the like.

Description

technical field [0001] The invention relates to a magnetic levitation driven knitting needle selection method and device, in particular to a knitting needle selection method and device for a computerized jacquard circular weft machine, belonging to the technical field of textile machinery products. Background technique [0002] In textile machinery, jacquard circular knitting machine is used to carry out jacquard on the fabric to weave various patterns and patterns. It is mainly composed of yarn feeding mechanism, loop forming mechanism, pulling and curling mechanism, transmission mechanism and auxiliary mechanism. The needle selection method and structure design of knitting needles is the direction of modern new loom technology improvement. The electronic needle selection devices of the known computerized jacquard circular weft machines are mainly electromagnetic and piezoelectric. Cams, jacquard pieces, needle jacks and other mechanical parts realize needle selection. Sin...
