【背景和目的】烟支密端位置是加工精度的表征指标,其发生偏移往往会造成烟支烟丝分布变化。本文目的是准确表征密端位置对卷烟物理指标、烟支空头、主流烟气等的影响规律,探索最优工艺条件。【方法】为此,开展了密端位置偏移量梯度试验。【结果】(1)密端位置偏移会导致内外排烟支的吸阻、硬度、感官质量、抽吸口数、焦油量产生差异,且随着密端位置偏移量的增加,内外排烟支的差异越明显,特别是密端位置偏移达到3 mm以后,差异更为显著;(2)密端位置偏移也会导致烟支空头缺陷支数增加,且点烟端密端减少烟支的空头增加数量要高于点烟端密端增加烟支;(3)随着密端位置的偏移,单密端内外排烟支重量还会产生差异,从而导致单密端内外排烟支质量的差异大于双密端。【结论】为提高内外排烟支质量的一致性,宜采用双密端的六槽平准器,密端位置偏移量不宜大于3 mm。
Abstract：Compaction position is the characteristic index of machining precision. The compaction position bias often affects the tobacco distribution and the cigarette quality. This paper carries out the compaction position bias gradient test and explores the effect of compaction position on cigarette physical indexes, smoke bears, and mainstream flue gas. Results showed that:(1) The compaction position bias led to the difference in the resistance, hardness, sensory quality, puff number, and tar amount of the inside and outside cigarette outlets, and such difference became increasingly significant with the increase of the compaction position bias. In particular, the difference was more significant after the position shift reached 3 mm.(2) The compaction position bias also led to an increase in the number of cigarettes with loose ends, and the number of cigarettes with decreased compaction ends reducing was larger than the number of cigarettes with increased compaction ends.(3) With the movement of the compaction position, the weight of the inside and outside cigarette with single compaction also differed, so there was a greater difference in the quality of the inside and outside cigarette with the single compaction than that with the double compaction. In order to improve the consistency of quality of the inside and outside cigarette, it was advisable to use a six-slot leveler, with the compaction position bias less than 3 mm.
