Research on a method to reduce the empty head rate of cigarettes in cigarette machines

This article mainly focuses on the study of how to reduce the empty head rate of cigarettes in the production process of cigarettes. At present, almost all needle roller components in cigarette systems are driven by DC closed-loop speed regulation, and their speed is controlled by DC voltage, which directly affects the structure and quality of cut tobacco, thereby affecting the degree of cut tobacco falling, i.e. the empty head rate. The system has not yet achieved automatic matching of needle roller speed with different tobacco cutting structures, resulting in fluctuations in empty head rate. The aim of this study is to address this issue by first establishing a regression equation for the structure of tobacco and achieving automatic calculation of the structural coefficients of tobacco; Secondly, with the cigarette empty head rate as the control objective, a regression fitting model for the structural coefficient of tobacco and the needle roller voltage is established, and it is integrated into the control system to achieve automatic adjustment of the needle roller speed. The experimental results indicate that the average empty head rate of each cigarette brand decreased from 0.26% to 0.16%. The method proposed in this study demonstrates significant potential for both promotion and practical application.
