目的 对GDX1/2卷烟包装机组CH烟包补充器进行改进研究，以减少其在生产过程中透明纸擦伤的缺陷率。方法 生产过程中，烟包补充器底部烟包透明纸擦伤的质量缺陷率较高。通过对补充器工作原理的分析，确定补充器内最下方的烟包底部表面长时间处于摩擦状态是导致透明纸擦伤的主要原因。设计一种二维运动机构，可以实现底部烟包和生产烟包分离的补充器，以避免烟包之间的摩擦，从而解决该位置产生的透明纸擦伤现象。结果 改进后的烟包补充器结构简单，因透明纸擦伤的产品市场投诉数量降低了22.2%。结论 该优化设计可有效减少CH烟包补充器位置的烟包擦伤质量缺陷。

The work aims to study the improvement of the CH cigarette pack replenisher of GDX1/2 cigarette packing unit to reduce the defect rate of transparent paper scratch in production. During production, the quality defect rate of the transparency paper was slightly high. Through analysis on the working principle of the replenisher, it was determined that the main reason for the scratch of the transparent paper was that the bottom surface of the cigarette pack in the replenisher was in the friction state for a long time. A two-dimensional movement mechanism was designed to separate the bottom cigarette pack and the production cigarette pack, so as to avoid the friction between the cigarette packs and solve the scratch phenomenon of transparent paper at this position. The structure of the improved cigarette pack replenisher was simple, and the market complaint on scratch of the transparent paper was reduced by 22.6%. This design can effectively reduce the quality defect of cigarette abrasion at the position of the CH cigarette pack replenisher.
