YJ27型加热卷烟接装机双路供料系统的设计

Design of dual-track feeding system for heated tobaccoproduct assembling machine YJ27

为解决YJ27型加热卷烟接装机因供料系统烟支堵塞和烟芯段折断而造成设备故障停机等问题,对原供料系统进行分析,结果显示取烟轮取烟速度过快是主要故障原因。在原系统基础上设计了一种双路供料系统,通过左右两个取烟轮同时取料,以降低取烟速度;重新设计供料系统的取烟轮、传送轮、合一轮、加速轮等鼓轮参数及对应齿轮,确保双路供料系统与主机物料传递相位同步。以玉溪卷烟厂生产的“MC”牌加热卷烟为对象进行测试,结果表明:改进后接装机运行效率由72.90%提升至90.55%,烟支质量不合格率由11.69%降低至1.37%,因供料系统烟支堵塞和烟芯段折断而造成的设备停机次数为0。该技术可为提升加热卷烟设备运行效率、降低原辅料消耗提供支持。

Tobacco rod jam or broken in the feeding system of heated tobacco product(HTP)assembling machine YJ27 tends to cause machine shutdowns,by analyzing the feeding system,it was found that the excessively high tobacco rod picking speed of the transfer drum was the main cause of the malfunction.A dual-track feeding system was designed based on the original system.The picking speed was slowed down by simultaneously picking tobacco rods through a pair of pick-up drums.The parameters and corresponding gears of the pick-up drum,transfer drum,combining drum,and accelerating drum in the feeding system were redesigned to synchronize the dual-track feeding system with the main machine.The redesigned system was tested on“MC”brand HTPs at Yuxi Cigarette Factory.The results showed that the operating efficiency of the machine increased from 72.90%to 90.55%,and the proportion of unqualified HTPs decreased from 11.69%to 1.37%.The number of machine shutdowns caused by the tobacco rod jam or broken in the feeding system was reduced to zero.This technology supports the promotion of operating efficiency of HTP production and the reduction of tobacco and material consumption.
