一种新型烟丝结构靶向调控设备研发及应用

Development and application of a novel cut tobacco structuretargeted control device

针对细支卷烟烟丝长丝率偏高,在卷制时易造成烟支质量波动较大、稳定性较差、不合格率高等问题,研制了一种针辊式烟丝结构靶向调控设备。该设备由烟丝选丝机构和断丝机构组成,混配后的烟丝进入烟丝选丝机构,在动态滚动状态下,中、短烟丝经针辊间隙落下,长烟丝则在选丝针辊钢钉挑动作用下逐级传递到断丝机构,在选丝针辊和断丝针辊差速旋转拉扯作用下柔性断丝,实现对长烟丝的靶向调控。以黄金叶(爱尚)细支卷烟烟丝为样品,在实际制丝生产的应用结果表明:该设备稳定性较高,在选丝针辊间距40 mm、选丝针辊电机频率30 Hz、断丝针辊电机频率47 Hz的运行参数下,经调控处理后的烟丝长丝率下降了12.58%,中丝率和短丝率分别上升了8.12%和3.96%,碎丝率仅增加了0.12%,烟丝结构分布更加合理,满足加工质量要求。

Due to the problems of high filament ratio of fine branch tobacco,the quality of large tobacco fluctuation greatly,the poor stability is and the high unqualified rate is high.In order to solve the above problem,a kind of needle roller cut tobacco structure control equipment was developed to realize the targeted control of filament.The device consisted of a cut tobacco screening mechanism and a cut tobacco breaking device which were different from those previously reported.The mixed cut tobacco went into the cut tobacco screening mechanism.In the dynamic rolling state,the medium and short cut tobacco falled through the gap between the needle rollers,and the long cut tobacco was transferred step by step to the wire breaking mechanism under the action of the steel nail of the needle roller.The wire breaking was realized under the action of the differential rotation and pulling of the needle roller and the needle breaking roller.The application results of gold leaf(Aishang)fine count cigarette cut tobacco as a sample in actual tobacco production showed that the equipment had high stability.Under the operating parameters of needle roller spacing of 40 mm,wire selection roller motor frequency of 30 Hz,and wire breakage roller motor frequency of 47 Hz,the tobacco long cut rate after regulation treatment decreased by 12.58%,while the medium cut rate and short cut rate increased by 8.12%and 3.96%,respectively.The broken cut rate only increased by 0.12%,and the distribution of tobacco structure was more reasonable,meeting the processing quality requirements.
