烟包垂直分切机卸料装置的优化设计

Optimization of discharge system of vertical slicer for unpacked tobacco

为解决烟包分切后烟块出现排列无序或堆叠现象进而造成松散回潮机入口流量不稳定问题,对烟包垂直分切机卸料装置进行了优化设计。采用带有可旋转卸料板的底板替代卸料装置原固定底板,导料装置由倾斜的平面板改为弧形滑板,在可旋转卸料板的作用下,切后烟块沿弧形导料装置滑落至输送带上。以湛江卷烟厂生产的“双喜”牌卷烟所使用的标准烟包为对象进行测试,结果表明:卸料装置改进后烟块排列紧凑且未产生堆叠现象,松散回潮机入口流量标准偏差均值由70.08 kg/h下降至41.42 kg/h,降低40.9%;出口含水率标准偏差均值由1.74%下降至1.51%,降低0.23百分点。该技术可为提高松散回潮工序来料稳定性提供支持。

In order to stabilize the throughput of the ordering cylinder,the discharge system of the vertical slicer for unpacked tobacco was optimized.A rotary vane discharger was used to replace the original solid bottom of the discharge system;the guide device was changed from an inclined flat plate to an arc-shaped plate.The rotary vanes push the sliced tobacco to slide along the arc-shaped guide plate and fall on the conveyor belt.The modified slicer was tested on the standard tobacco cases for manufacturing cigarettes of“Shuangxi”brand in Zhanjiang Cigarette Factory.The results showed that the sliced tobacco was lined up compactly and orderly,the mean standard deviation of the throughput of the ordering cylinder reduced from 70.08 to 41.42 kg/h,or by 40.9%;the mean standard deviation of moisture content in output tobacco decreased from 1.74%to 1.51%,or by 0.23 percentage points.This technology provides a support for promoting the throughput stability in tobacco ordering.
