Abstract

The weft inserter is the core component of the piece shuttle loom, in which the weft inserter needs to hold the weft yarn and go through the process of launching, flying, braking and so on. In order to improve the acceleration performance of the weft inserter, according to the magnetization theory, it is proposed to increase the magnetic flux difference by adding permanent magnets to the weft inserter to increase the applied magnetic field force by comparing the position of the permanent magnet material in the weft inserter and analyzing the electromagnetic force on the weft inserter with the addition of the permanent magnet using Ansys Maxwell finite element software. The results show that the addition of a permanent magnet sheet at the end of the weft inserter increases the magnetic field gradient on both sides of the device and enhances the electromagnetic force.
