储柜出料系统的优化设计

Optimization of tobacco silo discharge system

为解决储柜料头和料尾阶段出料流量低、时间长造成回潮机片烟出口含水率波动等问题,对储柜出料系统进行了改进。增加了作用于料头阶段的料头检测及控制装置,利用控制算法动态调整出料流量;设计了作用于料尾阶段的拨料辊自动平移系统,并结合底带运行速度优化出料运行模式,避免拨料辊阻碍物料,加快物料排出。以秦皇岛烟草机械有限责任公司生产的GPT15D储柜为对象进行测试,结果表明:改进后储柜料尾排出时间缩短38.1%,料头和料尾阶段回潮机片烟出口含水率不合格时间分别减少45.7%和59.2%,切丝机运行时间减少12.0%。该技术可为提高储柜出料效率、提升卷烟工艺质量提供支持。

As a solution to the problems of fluctuation of moisture content in output strips from conditioning cylinder during head and tail tobacco discharge stages of a silo, the discharge system of the tobacco silo was modified. A head tobacco monitoring and control device was designed for the initial stage to dynamically regulate the head tobacco throughput with control algorithm;an automatic translated system for picker roller was designed for the final stage to prevent it from blocking tobacco discharge. The bottom belt of the silo was accelerated via optimizing the discharge mode to speed up tail tobacco discharge. The modified discharge system was tested on a GPT15D silo manufactured by Qinhuangdao Tobacco Machinery Limited Corporation, the results showed that the tail tobacco discharge stage shortened by 38.1%, the time of output strips with unqualified moisture content at head tobacco stage and tail tobacco stage reduced by 45.7% and 59.2% respectively, and the running time of tobacco cutter decreased by 12.0%. This technology provides a support for promoting the discharge efficiency of silo and the process quality of cigarettes.
