德国Malimo缝编机的平行衬纬改造

Modification of Malimo stitch-knitting machine for parallel weft insertion

对现有进口缝编机进行技术改造,使其满足产品不断更新换代的需要。在老式德国进口缝编机的衬纬机构上加装平行双曲柄机构,延长了铺纬机构的静止时间;采用PLC控制的机、电、气一体化技术进行改造,使衬纬机构的运动准确,动作协调、可靠,达到了对原设备做尽可能小的改动而实现平行衬纬的要求。

To meet the changing needs of product upgrading,a technological modification was performed on the present Malimo stitch-knitting machine imported from German by installing a parallel double-crank mechanism on the weft insertion device so that the residence time of the weft insertion device was prolonged.PLC controlled pneumatic executing mode was affected by means of the electromechanical integration modification.Thus,the weft insertion devices operated accurately,coordinately and reliably,meeting the requirements of parallel weft insertion by the least possible modification of the original equipment.
