【目的】解决ZJ118型卷接机组在生产细支卷烟时，因接烟轮承烟槽对烟支支撑不足导致的烟支表面皱纹的质量问题。【方法】基于SOLIDWORKS三维模型功能设计了一种新型多点面支承的接烟轮承烟槽，代替原有单点支承的接烟轮承烟槽，并通过COMSOL Multiphysics仿真分析烟支在接烟轮承烟槽上时烟支的应力分布情况，然后在实际生产中验证新型多点面支承的接烟轮承烟槽的应用效果。【结果】仿真分析的结果表明，新型多点面支承的接烟轮承烟槽上细支卷烟的应力分布情况和高速下烟支表面光滑度都比原有单点支承的接烟轮承烟槽好。新型多点面支承的接烟轮承烟槽上烟支受力分布更均匀，烟支受到的负压风也更均匀，能够更好地保证烟支外观质量的稳定性。实际应用效果显示，使用新型多点面支承的接烟轮承烟槽后，因接烟轮承烟槽导致的细支烟支表面皱纹质量缺陷由18.40支/班降低为0。【结论】新型多点面支承的接烟轮承烟槽结构具有对烟支支撑性好、应力分布均匀、吸风稳定等优点，可以更有效地改善卷烟表面质量，大大减少了烟支表面皱纹事故出现和设备停台维修频次，降低了卷烟生产物料消耗。

[Objective] This study aims to address the quality issue of wrinkles on the cigarette surface caused by insufficient support from the cigarette carrying slot on the transfer drum in the ZJ118 cigarette making and assembling machine during the production of slim cigarettes. [Methods] A new multi-point surface-supported cigarette carrying slot for the transfer drum was designed using the 3D modeling capabilities of SOLIDWORKS, replacing the original single-point supported slot. COMSOL Multiphysics was used to simulate and analyze the stress distribution on the cigarette in the new slot. The actual performance of the new multi-point surface-supported slot was then verified in production. [Results] The results of simulation analysis showed that the stress distribution and the smoothness of the cigarette surface at high speeds were better with the new multi-point surface-supported slot compared to the original single-point supported slot. The stress distribution on the cigarette in the new slot was more even, and the negative pressure airflow was also more uniformly distributed, effectively ensuring the stability of the cigarette's external quality. The actual application results showed that the surface wrinkle defect rate caused by the cigarette carrying slot decreased from 18.40 defects per shift to 0 when using the new slot. [Conclusion]The new multi-point surface-supported cigarette carrying slot structure offers better support, more even stress distribution, and more stable suction, effectively improving cigarette surface quality. It significantly reduces cigarette surface wrinkle incidents and the frequency of equipment downtime for repairs, as well as lowering material consumption during cigarette production.
