卷烟机平准盘最佳凹槽深度研究

Study on the optimal depth of groove of leveling plate of cigarette making machine

【目的】为研究更加适宜的卷烟机平准盘凹槽深度,提升卷烟产品质量品质。【方法】利用无凹槽平准盘对云烟某牌号卷烟进行试验,通过硬度、空头、端部落丝量等指标确定最佳紧头和中段密度,根据经过平准盘后吸丝带下方烟丝束与成品烟条内相应部位烟丝含量相等,推算出凹槽体积的计算方法,最终确定卷烟机平准盘最佳凹槽深度并进行验证。【结果】(1)试验卷烟的紧头与中段最佳密度比约为1.17;(2)深槽弧长为18 mm,浅槽弧长为12 mm时,平准盘最佳紧头凹槽深度为2.8~3.5 mm,接嘴端凹槽深度为1.5~2.0mm;(3)确定后的最佳平准盘投入使用后卷烟物理指标较好且质量稳定。【结论】通过该计算方法计算出的凹槽深度具有较好实用性,可用于平准盘凹槽深度的快速优化。

[Background]This study aims to investigate the optimal depth of groove of leveling plate of cigarette making machine and improve the quality of cigarettes.[Methods]The experiment of certain brand of Yunnan cigarette was carried out by using the leveling plate without groove.The density of dense-end and middle section could be determined through indicators such as hardness,short,end band silk amount.After passing through the leveling plate,according to the tobacco bundle under the ribbon and the corresponding part of the finished cigarette strip,calculate the groove volume,finally determine and verify the optimal groove depth of the leveling plate of cigarette making machine.[Results]Test data show:1)the optimal ratio of dense-end density to middle section density is around 1.17;2)when the deep groove width is 18mm,the shallow groove width is 12 mm,the optimal depth of deep groove is 2.8-3.5 mm and that of shallow groove is 1.5-2 mm;3)the physical index of cigarette is better and the quality is stable after the optimal leveling plate is put into use.[Conclusion]The groove depth calculated by this method has good practicability and can be used for the rapid optimization of the groove depth of the leveling plate.
