GDH1000包装机组烟库线性电机防尘装置的改进

摘要

为解决GDH1000包装机组烟库线性电机轴部位易积尘、磨损快、电机更换频次高等问题,对线性电机防尘装置进行了改进.采用压缩空气防尘方式,通过在电机轴端制作并安装环状气腔引入压缩空气,在电机轴周围形成环状气帘和气垫,以隔绝和清洁散落在电机轴上的烟尘.应用效果表明,改进后的防尘装置有效解决了电机轴套部位积尘问题,清洁效果良好,避免了因积尘导致电机轴与轴套磨损的现象.电机更换频次由6个月更换18件减少到更换1件,延长了电机使用寿命,半年节省费用20多万元,提高了设备运行效率.%The dust buildup on the shaft of linear motor in cigarette hopper in GDH1000 packer accelerated the elements' wear and reduced motor' s life.Therefore,the dustproof device for linear motor was improved by making and installing a cavity ring around the end of motor shaft and introducing compressed air to form an annular air curtain and cushion around motor shaft to prevent dust buildup.The results of application showed that the new dustproof device effectively eliminated the dust buildup on motor shaft sleeve,the wear between motor shaft and sleeve caused by dust buildup was avoided.Motor replacement reduced to once from 18 times per 6 months,which saved more than 200 thousand RMB yuan in cost.And the machine efficiency was increased.
