Abstract:In view of the problems of low efficiency and poor operation of the existing circular weft insertion mechanism and its drive，the development status of the circular weft insertion technology is introduced，and a new type of magnetic levitation circular weft insertion mechanism is proposed.The structure model and working principle of the new weft insertion mechanism are described in detail.The magnetic field variation of the weft insertion mechanism and the magnetic field force variation of the shuttle are simulated and analyzed by the electromagnetic simulation software Ansys Maxwell，and the feasibility of the method is verified by experiments. It is pointed out that the new circular weft insertion mechanism adopts permanent magnet to suspend the shuttle in the circular guide rail，and the driving mechanism uses “E”coil，and by controlling the direction and magnitude of the current to control the direction and magnitude of the magnetic field，the continuous circular motion of the shuttle on the track can be realized，so as to complete the weft insertion action.Through experiments，it is found that the voltage of 18 V and air gap of 5 mm are most suitable for the mechanism.The new weft insertion mechanism can improve the weft insertion efficiency and lay a foundation for improving the weaving efficiency of loom.
