摘要:针对烟包在卷烟包装机输送过程中时常发生运行不畅的问题，基于6种典型商标纸在不同摩擦接触面上摩擦系数的差异性，分别探讨了商标纸摩擦系数对卷烟包装机开、停机时和八轮后烟包输送的影响。结果表明，实际生产中使用的传送带为接触面时测得的摩擦系数能更准确地反映商标纸的表面摩擦状况。对卷烟包装机停机与开机时的烟包进行受力分析，通过测量商标纸与所用传送带间的摩擦系数，计算烟包所受摩擦力大小，根据卷烟包装机的生产速度、制动（释放）时间等参数可以预测烟包在输送过程中的运行状况。卷烟包装机八轮后输送阶段，可以根据烟包2个接触侧面的动摩擦系数的相对大小来调节上传送带对烟包施加的压力，以保证烟包平稳运行。

Abstract:Addressing the frequent issues of poor packet conveyance, the influence of frictional coefficients of typical cigarette packet packaging paper on conveying during machine startup, shutdown, and after the No.8 wheel was explored based on the differences in these coefficients among several typical papers on different contact surfaces.The results showed that the frictional coefficient measured with the conveyor belt used in actual production as the contact surface could more accurately reflect the surface friction condition of cigarette packet packaging paper. A force analysis was performed on the cigarette packets during both the shutdown and startup phases of the packaging machine. By measuring the coefficient of friction between the cigarette packet packaging paper and the conveyor belt used, the friction force on the cigarette packets could be calculated, and then, based on parameters such as the production speed and braking (releasing) time of the cigarette packaging machine, the operating status of the cigarette packets during conveyance could be predicted. The pressure exerted on the cigarette packets by the upper conveyor belt could be adjusted according to the relative magnitude of the coefficient of dynamic friction between the two contacting sides of cigarette packets to ensure stable running of the cigarette packets.
