新型叶丝限长设备

New Equipment of Restriction of Cut Tobacco Length

为大幅降低叶丝长丝率,改善烟丝结构,设计了一种叶丝限长设备。该设备的部件通过键联方式连接,并可通过调整打辊的间隙套的厚度和改变方刀之间的间隙,获得所需烟丝限长效果,具有操作简单、拆装方便、成本较低、适应性强的特点。实际应用效果表明:应用前后叶丝的长丝率降低约7%和叶丝的中丝率提高约4%,可见,这种设计能够有效改善烟丝分布的均匀度,减少卷烟燃烧端掉落现象的发生。

In order to reduce the rate of cut tobacco with long size substantially and improve cut tobacco structure effectively, the equipment used for restriction of cut tobacco length was developed. The assembly units on this equipment are jointed by shaft key and designed identically. The different restriction effect of cut tobacco length can be gained just by adjusting thickness of roller gap bridging and gap between the square cutters. This equipment is easy to operate, simple to maintain, cost-effective and adaptable. The practical effect of its application showed that this equipment could lower the rate of cut tobacco with long size by about 7% and increase the rate of cut tobacco with middle size by about 4 % before and after this application. Thus it can be seen that this design could improve the equilibrium of distribution of cut tobacco and decrease the frequency of failing fire end effectively.
