Abstract:

In order to solve the problem that the weft insertion is difficult in the development of the super width automatic loom, the weft insertion design method based on the coil electromagnetic launch for the super width automatic loom was proposed innovatively. According to weft insertion process requirements on the super width automatic loom, the analysis and calculation model of the maximum flight speed of the clip weft device was established. The composition and working principle of the coil electromagnetic launch weft insertion mechanism were analyzed. The magnetic field characteristics of the coil electromagnetic launch weft insertion mechanism were analyzed. The magnetic field characteristics of the coil electromagnetic launch weft insertion mechanism were researched. The weft insertion electromagnetic force was calculated by different methods, and was simulated by computer. The results of analysis and calculation show that the 7 stages coil launch work is 182.21 N?m, which can meet the requirement of 174.64 N?m of the weft insertion of the super width automatic loom.
