Influences of the pin-roll tobacco structure control equipment parameters on the rolling quality of slim cigarette
Using single quality standard deviation,suction resistance standard deviation,total ventilation rate stand-ard deviation,end thread amount,and end content as indicators,an orthogonal experiment was designed with three parameters:wire selection needle roller motor frequency,wire breakage needle roller motor frequency,and wire selection needle roller spacing,to study the effect of parameter changes in pin-roll tobacco structure control equip-ment on the rolling quality of fine cigarette production.The results showed that the frequency of the wire selection needle roller motor was a key factor affecting the standard deviation of the total ventilation rate and single cigarette weight;the frequency of the wire breakage needle roller motor was a key factor affecting the standard deviation of suction resistance and the amount of wire at the end;the distance between the wire selection needle rollers was a key factor affecting the end content.The optimal parameters for regulating the equipment were the frequency of the wire selection needle roller motor at 33 Hz,the frequency of the wire breakage needle roller motor at 45 Hz,and the spacing between the wire selection needle rollers at 45 mm.After regulation,the long cut tobacco rate decreased by 14.39%,while the medium and short cut tobacco rates increased by 26.01%and 20.09%,with little change in the broken tobacco rate.After rolling,there was no significant change in the physical indicators of fine cigarettes,but the standard deviation of single cigarette quality,suction resistance,and total ventilation rate decreased by more than 30%.The end tobacco content and end tobacco content decreased by 61.79%and 36.42%,respectively.The stability of fine cigarette rolling was efficiently improved.
