一种减少靠拢轮产生刺破烟的改进

An Improvement to Reduce Puncture Defects Caused by the Compacting Wheel

摘要: 在PROTOS系列ZJ116卷接机组生产中，因烟丝含梗量较高及供丝机除梗不完全，卷烟内部易残留烟梗，而滤嘴接装阶段切纸鼓轮与传统靠拢鼓轮的挤压作用，易导致烟梗刺破卷烟纸形成不合格刺破烟支。为此，本文基于滤嘴烟支成型工艺流程，提出优化靠拢鼓轮结构的改进方案，通过赫兹接触理论的分析增设挤压形变区增大烟条受压缓冲空间，在不改变接装纸与烟组压缩量、保证搓接质量的前提下降低烟条所受挤压力，应用效果验证表明，该方案可显著降低刺破烟支发生率，为卷烟生产质量提升提供了技术支撑。

Abstract: In the production of the PROTOS series ZJ116 cigarette making machine, due to the high stem content in the tobacco and incomplete stem removal by the tobacco feeding machine, tobacco stems are easily left inside the cigarettes. During the filter assembly stage, the compression between the paper cutting drum and the traditional converging drum easily causes the tobacco stems to pierce the cigarette paper, resulting in defective cigarettes. Therefore, this paper proposes an improved solution to optimize the structure of the converging drum based on the cigarette filter forming process. By analyzing the Hertz contact theory, a compression deformation zone is added to increase the buffer space for the tobacco rod under pressure. This reduces the compressive force on the tobacco rod without changing the compression amount between the wrapping paper and the tobacco rod, while ensuring the quality of the joining process. The application results show that this solution can significantly reduce the incidence of pierced cigarettes, providing technical support for improving cigarette production quality.
