接装纸通风率数学模型在混合型卷烟设计中的应用

Application of Mathematical Model for Ventilation Rate of Tipping Paper in Blended Cigarette Design

为了得到不同焦油量的混合型卷烟产品,考察和测试了一排、两排在线激光打孔条件下的卷烟总通风率、接装纸通风率、卷烟纸通风率三者之间的关系,建立了接装纸通风率与焦油之间的数学模型。结果表明:①在总通风率低的情况下,卷烟纸的通风率起主要作用;在总通风率高的情况下,接装纸的通风率起主要作用,而卷烟纸的通风率作用逐步减小;②对于低焦油混合型卷烟产品,特别是接装纸通风率稳定在45%左右的产品,应采用两排在线激光打孔;而接装纸通风率较低,焦油量相对高的产品,一般采用一排激光打孔;③建立了接装纸通风率与焦油之间的数学模型,通过该模型计算出接装纸通风率,再调整在线激光打孔的技术参数,可实现产品设计的技术要求。

In order to obtain blended cigarette products with different tar deliveries, the relationship among the ventilation rates of cigarette, tipping paper and cigarette paper was investigated with single-line or two-line online laser perforation, and a mathematical model between the ventilation rate of tipping paper and tar delivery was established. The results showed that ： 1 ） for cigarette of low ventilation rate, the ventilation rate of cigarette paper played a major role ; while for cigarette of high ventilation rate, the ventilation rate of tipping paper played a major role; 2） for blended cigarette products of low tar delivery, especially those with the tipping paper of about 45% ventilation rate, two-line online laser perforation should be adopted ; for blended cigarette products of relatively higher tar delivery with low ventilation tipping adopted; 3） the parameters of online laser perforation tipping paper calculated with the mathematical model to paper, single-line online laser perforation was generally could be adjusted according to the ventilation rate of meet the requirements of product design.
