目的 为解决预制条盒中支“玉溪境界”软盒硬化产品生产过程中存在的人工包装效率低下且成本较高问题。方法 通过对YB65条盒包装机进行结构分析和改进，仅保留原机的二五排列的烟包推入装置，重新设计预制条盒供料及侧盖打开装置、烟包推入装置及预制条盒输出装置。预制条盒装填技术改变了原有条盒纸成型工艺，并对YB65条盒包装机与YB95条盒透明纸包装机的设备布局及相位进行调整，实现了侧开式预制条盒卷烟的包装成型工艺。结果 以中支“玉溪境界”为测试对象，装填设备联机运行时速度达25条/min，设备效率达75.4%，废品剔除率为0.84%，较人工装填效率提升了19.3倍。结论 设备投入使用后，实现了侧开式预制条盒卷烟的全自动生产，设备运行稳定可靠，且效率提升显著。

The work aims to solve the inefficiency and high cost of manual packaging in the production process of soft box hardening product of "Yuxi Jingjie" in prefabricated carton. Through structure analysis and improvement on YB65 carton packaging machine, only the 25-row cigarette bag pushing device of the original machine was retained. The prefabricated carton feeding and side cover opening device, the cigarette bag pushing device and the prefabricated carton output device were redesigned. The prefabricated carton filling technology changed the original carton paper forming process, and adjusted the equipment layout and phase of YB65 carton packaging machine and YB95 carton transparent paper packaging machine, thus realizing the packaging process of side-open prefabricated carton cigarette. Taking "Yuxi Jingjie" in Zhongzhi as the test object, the online running speed of filling equipment reached 25 cartons/min, the equipment efficiency reached 75.4%, the rejection rate of waste was 0.84%, and the efficiency of was increased by 19.3 times compared with manual filling. After putting the equipment into service, the fully automatic production of side-open prefabricated carton cigarettes is realized. The equipment runs stably and reliably, and the efficiency is improved significantly.
