A projectile loom with superconducting magnetic levitation weft insertion and its control method

Abstract

A superconducting magnetically levitated weft insertion jib loom includes a jib, an electromagnetic shuttle-throwing device, a magnetically levitated weft insertion device, an electromagnetic shuttle-controlling device, and a three-axis moving suction cup. The electromagnetic shuttle-throwing device includes a first permanent magnet array track and a first electromagnetic coil array track, with the first electromagnetic coil array track positioned on both sides of the first permanent magnet array track. The electromagnetic shuttle-controlling device includes a second permanent magnet array track and a second electromagnetic coil array track, with the second electromagnetic coil array track positioned on both sides of the second permanent magnet array track. The magnetically levitated weft insertion device includes a third permanent magnet array track. The jib includes a shuttle body and a Dewar container. Permanent magnet arrays are symmetrically installed on both sides of the shuttle body. A weft clamp is installed inside the shuttle body. The Dewar container is filled with liquid nitrogen, and a superconductor is inserted into the bottom of the Dewar container. This design not only achieves controllable jib weft insertion speed but also improves the applicability of jib weft insertion.
