为解决FOCKE 800硬盒包装机烟库内烟支堵塞、下烟不顺畅等问题，通过分析烟库形状、烟支流动等因素对烟支下落速度的影响，对烟库搅动块装置进行了改进。将烟库中静止的4个分流圆柱改为两个活动的圆形搅动块，由原驱动搅动辊电机通过四连杆机构驱动圆形搅动块搅动烟支，实现烟支分流。采用离散元仿真模型模拟烟库中烟支流、搅动块的搅动情况。结果表明：①建立的虚拟烟库仿真模型，符合烟支流的实际要求，仿真结果与实际值相比较，二者基本吻合。②将烟库中的搅动块由固定改为运动状态，变形烟支率明显减少；当搅动块摆动频率1.6 Hz，摆动角度11.2°，运行时间9.0 s时，变形烟支率减少2.5%，变形烟支率最小。烟库内烟支流动平稳，受力均匀，包装机运行状态良好。利用该离散元仿真模型可有效分析烟库中烟支分流情况，减小产品开发成本，缩短产品研发周期。

To solve the problems of cigarette jam and staggering falling in discharge channel of cigarette hopper in FOCKE 800 hard packer, the stirring device in cigarette hopper was modified via analyzing the factors, such as hopper shape and cigarette flowing, influencing cigarette falling. The four fixed deflectors were replaced by two round movable stirring parts, which were driven by the driving motor of original stirring rollers via a four-linkage mechanism, to stir cigarettes and split cigarette flow. The cigarette flow in cigarette hopper and the stirring action of stirring parts were simulated with a discrete element simulating model. The results showed that: 1) The established simulation model of virtual cigarette hopper met the actual requirements of cigarette flow, and the simulated results basically agreed with actual values. 2) The amount of distorted cigarettes reduced obviously once the stirring parts in cigarette hopper became movable. When the swing frequency, swing angle and running time of stirring parts were 1.6 Hz, 11.2° and 9.0 seconds respectively, the percentage of distorted cigarettes was minimized and decreased by 2.5%. Cigarettes in hopper move fluently, and the packer runs smoothly. The discrete element simulation model can effectively analyze the splitting status of cigarette flow in hopper and cut the cost and time for product research and development.
