正交试验在ZJ17型卷烟机梗签剔除中的应用

Application of Orthogonal Test in the Removal of Slivers by Using ZJ17 Cigarette Machine

为研究ZJ17型卷烟机梗签剔除工艺参数对烟支中梗签含量的影响,在卷烟机处于正常生产状态下,采用正交试验研究挡板高度、正压吹风、针辊电机频率对卷烟机剔除量、烟支中梗签含量及剔除物中含丝率的影响。结果表明:对卷烟机剔除量的影响从大到小依次为正压吹风、挡板高度和针辊电机频率。其中,正压吹风和挡板高度对卷烟机剔除量的影响达到极显著水平。对烟支中梗签含量的影响从大到小依次为挡板高度、正压吹风和针辊电机频率。其中,挡板高度对烟支中梗签含量的影响达到显著水平。对剔除物中含丝率的影响从大到小依次为正压吹风、挡板高度和针辊电机频率。其中,挡板高度和正压吹风对剔除物中含丝率的影响达到显著水平。随着挡板高度的上升,卷烟机剔除量呈上升趋势,烟支中梗签含量呈下降趋势,剔除物中含丝率呈上升趋势。随着正压吹风的增强,卷烟机剔除量呈下降趋势,烟支中梗签含量呈上升趋势,剔除物中含丝率呈下降趋势。综合考虑产品质量及经济指标,确定ZJ17型卷烟机生产"黄山(A)"牌号卷烟最佳梗签剔除工艺参数组合为挡板高度109 mm,正压吹风0.9 kPa,针辊电机频率44 Hz。

In order to study the effects of process parameters of ZJ17 cigarette machine on the content of slivers in cigarettes,under the normal production state of the cigarette machine,the effects of the baffle height,the positive pressure blower,the frequency of needle roller motor on the rejection quantity of the cigarette machine,the content of slivers in the cigarette and the cut tobacco percentage in rejects were studied by orthogonal test.The results showed that the order of the influence degree on the rejection quantity of the cigarette machine was the positive pressure blower>the baffle height>the needle roller motor frequency.At 1%significance level,the influences of the positive pressure blower and the baffle height on the rejection quantity of cigarette machine were significant.The order of the influence degree on the content of slivers in the cigarette was the baffle height>the positive pressure blower>the needle roller motor frequency.At 5%significance level,the influences of the baffle height on the content of slivers in the cigarette were significant.The order of the influence degree on cut tobacco percentage in rejects was the positive pressure blower>the baffle height>the needle roller motor frequency.At 5%significance level,the influences of the positive pressure blower and the baffle height on the content of the slivers in the cigarette were significant.As the the baffle height rose,the rejection quantity of the cigarette machine also increased,the content of the slivers in the cigarette also decreased,and the cut tobacco percentage in rejects also increased.As the the positive pressure blower increased,the rejection quantity of the cigarette machine also decreased,the content of the slivers in the cigarette also increased,and the cut tobacco percentage in rejects also decreased.Through comprehensive consideration of product quality and economic indicators,the optimum technological parameters for removing slivers of the"Huangshan(A)"brand cigarettes produced by the ZJ17 cigarette machine were as follows:the baffle height 109 mm,the positive pressure blower 0.9 kPa,the needle roller motor frequency 44 Hz.
