摘要
目前广泛使用的风力送丝系统,其核心设备是振盘式送丝机,安装在送丝机腔体顶部和侧面的吸丝管借助风力吸入烟丝。由于振盘的振动,容易发生烟丝造碎和分层,而上吸式和侧吸式吸丝管对风速要求较高,加剧了烟丝的造碎和分层,导致卷烟质量不稳定等问题。因此,设计了一种新型的下吸式送丝机,相较于振盘式送丝机的改进措施为:①将吸丝管的吸丝方式从上吸式或侧吸式改成下吸式,用落料方式给吸丝管喂料;②弃用振盘,采用拨辊来实现烟丝松散和均匀给料的目的,防止烟丝分层;③用逐步收口的落料斗给吸丝管喂丝,降低风力要求。改进后,对经过送丝机前后的整丝率和碎丝率进行多批测试,并与改进前对比,发现整丝率损耗降低了0.48%,碎丝率的增加降低了0.23%,送到卷烟机的烟丝结构更加均匀,提高了卷烟质量的稳定性。
The wind send cut tobacco machine which widely used its core equipment is the vibratory conveyor,the machine use the wind to cut tobacco from the machine body,the installation position of the absorb pipe is installed in the upper,side,The tobacco in the machine vibrate all the time,so it＇s easy to occur the layered cut tobacco situation.And it will cause the cigarette making machine absorb the different tobacco from the machine.In this case,it will cause the broken of the cut tobacco and filling power undulate.In order to overcome this problem,it is necessary to design a send cut tobacco machine that a belt conveyor and send cut tobacco machine can link together to completely eradicate the layered cut tobacco situation,the improvement measures is： First change the absorb pipe from the upper and side way to down position,Second use the roller to flex the tobacco in order to send the tobacco equality;Finally use the smaller hopper to send the tobacco in order to reduce the wind speed.In this way,we have tested the whole tobacco rate and the broken tobacco rate,the whole tobacco rate increased 0.48% and the broken tobacco rate reduced 0.23%,and the structure that send to the cigarettes making machine became much equality than before,and it also improve the cigarettes quality.
