Hybrid magnetic suspension knitting needle driving device and control method thereof

Abstract

The invention relates to a hybrid magnetic suspension knitting needle driving device. The hybrid magnetic suspension knitting needle driving device comprises a housing and a knitting needle; the housing is of a cylindrical structure; a coil skeleton is arranged in the housing in a sleeved manner; the coil skeleton is of a cylindrical structure; the inner circumferential surface of the coil skeleton is symmetrically provided with two radial supporting blocks along the central axis of the coil skeleton; each radial supporting block is equipped with an optic fiber displacement sensor in signal connection with a control system; a primary coil, a secondary coil and a tertiary coil are respectively wound around outer circumferential surfaces of the lower part, middle part and upper part of the coil skeleton; the primary coil, the secondary coil and the tertiary coil are all electrically connected with the control system; the knitting needle is arranged in the coil skeleton in an inserted manner; the middle part of the knitting needle is located between the two radial supporting blocks; the bottom part of the knitting needle is provided with a cylindrical permanent magnet; the permanent magnet is located in the lower part of the coil skeleton; and the permanent magnet and the coil skeleton are coaxial. The design not only reduces the response time of the device and increases the axialdisplacement of the knitting needle, but also simplifies the control process.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a hybrid magnetic suspension knitting needle driving device and a control method thereof, which are mainly applicable to reducing the response time of the device, increasing the axial displacement of knitting needles and simplifying the control process. Background technique [0002] In the field of textile machinery, the jacquard circular knitting machine performs jacquard on the fabric to weave various patterns and patterns. The electronic needle selection devices of the existing knitting needle computerized jacquard circular weft machines are mainly electromagnetic and piezoelectric, and they all use mechanical parts such as triangular cams, jacquard sheets, and needle jacks to select needles. The contact of the cam realizes the knitting movement up and down, therefore, the triangular cam in the knitting mechanism causes impact friction and lateral force to the knitting needle...
