螺旋筛分侧面喂入式配丝装置在卷烟厂风力送丝中的应用

为解决风力送丝配丝过程中存在的烟丝分层和含末率较高等问题,进一步提高烟丝输送过程的控制精度和稳定性,进行了新型螺旋筛分侧面喂入式配丝装置的应用试验。结果表明,与改进前相比,配丝过程中的烟丝分层和烟末筛分问题得到了有效解决,烟丝结构明显改善,中短丝率提高2.41%;整丝率提高2.34%;碎丝率降低1.55%;填充值提高0.12cm3/g;烟支单重量标准偏差降低4mg/支;卷烟吸阻降低32Pa/支;端部落丝量平均降低1.23mg/支,烟支含末率平均降低0.42%;卷烟焦油量平均降低0.16mg/支;CO量平均降低0.28mg/支,感官质量稳定提高。

Application of a New Screw Type Cut Tobacco Distributor in Pneumatic Feeding System

To solve the problems such as cut tobacco segregation and high fine content and improve the control precision and stability in pneumatic feeding system, a new screw type cut tobacco distributor featuring a tobacco sieve and laterally fed was tested. The results showed that: the mentioned problems were solved effectively, whereby the structure of cut tobacco improved obviously. The proportions of medium to short strands increased by 2.41% and that of long strands by 2.34%, respectively; the small particle content reduced by 1.55%; the filling power increased by 0.12 cm3/g; the standard deviations of individual weight and draw resistance of cigarettes reduced by 4 mg/cig. and 32 Pa/cig., respectively; the tobacco loss from cigarette ends, fine content, deliveries of tar and CO averagely reduced by 1.23 mg/cig., 0.42%, 0.16 mg/cig.and 0.28 mg/cig., respectively. And the smoking quality improved steadily.
