Research on Cigarette Extrusion Deformation Rate Control of ZB418 Packaging Machine Based on DOE Full Factorial Experiment

摘要: 针对高速卷烟包装过程中异形烟支(双铝包结构)在机械通道内的挤压变形问题，本文以ZB418型包装机组为研究对象，深入分析了烟包在成型与输送环节的运动学特性及受力状态。通过对生产现场的大样本数据统计与工艺环节分层测试，揭示了内衬及商标纸成型组件是导致烟支塑性变形的关键区域。基于机械接触力学理论，识别出干燥轮模盒宽度与内衬成型通道宽度为影响变形率的关键几何参数。采用全因子试验设计(DOE)方法，研究了关键参数对变形率的交互影响规律，确定了最佳工艺参数组合(干燥轮模盒宽度61.6 mm，内衬成型通道宽度32.0 mm)。工程应用结果表明，改进后的工艺参数使烟支挤压变形率从0.46%显著降低至0.092%，降幅达80%，有效提升了产品外观质量稳定性与生产效率，为同类高速包装设备的精密控制提供了理论依据与技术范式。

Abstract: This paper focuses on the extrusion deformation problem of irregularly shaped cigarettes (double aluminum pack structure) in the mechanical channel during high-speed cigarette packaging. Taking the ZB418 packaging machine as the research object, it analyzes the kinematic characteristics and stress state of the cigarette pack during the forming and conveying stages. Through large-sample data statistics from the production site and layered testing of process stages, it is revealed that the inner liner and label paper forming components are the key areas leading to the plastic deformation of the cigarette. Based on the theory of mechanical contact mechanics, the width of the drying wheel mold box and the width of the inner liner forming channel are identified as key geometric parameters affecting the deformation rate. Using the design of full factorial experiment (DOE) method, the interaction law of key parameters on the deformation rate is studied, and the optimal combination of process parameters (drying wheel mold box width 61.6 mm, inner liner forming channel width 32.0 mm) is determined. Engineering application results show that the improved process parameters significantly reduced the cigarette extrusion deformation rate from 0.46% to 0.092%, a reduction of 80%, effectively improving the stability of product appearance quality and production efficiency. This provides a theoretical basis and technical paradigm for the precision control of similar high-speed packaging equipment.
