| 目的 针对ZJ17卷接机YJ17供丝系统中烟丝堵塞、竹节烟和烟支标偏大的现象进行改进。方法 采用流体仿真分析软件Solidworks Simulation模拟分析、正交实验及试验验证的方法，设计优化YJ17供丝系统的风室装置，通过模拟仿真不同正压风入口形状、数量、位置对设备运行效率、产品质量的影响，找到三者最优的参数组合。模拟分析发现，在正压风入口形状为圆形，正压风入口数量为3个，正压风入口距离气室边缘的距离为15 mm时，风室气流分布更均匀，同时烟丝在离开抛丝辊后受到的下吹风力最大，可使烟丝快速到达吸丝带。结果 气室经改进后烟丝堵塞次数降低了39.3%，SD值(20支烟支质量标偏)降低了25%，有效提升了设备的运行效率和卷烟产品的质量。结论 基于仿真及正交实验结果，优化了风速出风口位置和直径，气室的流场分析结果可为烟丝吸丝成型及风室结构优化提供一定技术支持。 |

| The work aims to address the phenomenon of cigarette blockage, slub cigarette, and excessively large cigarette label in the YJ17 wire supply system of the ZJ17 cigarette machine. The method of the fluid simulation analysis software Solidworks Simulation, orthogonal experiments, and experimental verification was used to design and optimize the air chamber device of the YJ17 cigarette supply system. Through simulation of effect of different shapes, quantities, and positions of positive pressure air inlets on the operation efficiency and product quality of equipment, three optimal combinations were found. When the positive pressure air inlet shape was circular, with 3 positive pressure air inlets and a distance of 15 mm between the positive pressure air inlet and the edge of the air chamber, the air flow in the chamber was more uniform. When the cigarette left the throwing roller and was subject to the maximum and most uniform downward blowing force, the cigarette quickly reached the suction strip. After the improvement of the air chamber, the number of cigarette blockages decreased by 39.3%, and the SD value (weight deviation of 20 cigarettes) decreased by 25%, effectively improving the equipment operation efficiency and cigarette product quality. Based on simulation and orthogonal experimental results, optimizing the position and diameter of the air outlet and the flow field analysis results of the air chamber can provide certain technical support for the cigarette suction molding and the optimization of the air chamber structure. |
