M8设备改版软长嘴后故障分析和应对措施

Troubleshooting and solutions for M8 device after soft nozzle upgrade

摘要

本文围绕杭州卷烟厂A2型PROTOS-M8超高速卷烟机由软红长嘴改为软长嘴后的运行情况，分析了改版后设备在适配新辅料和结构变化中出现的三类典型故障：后一切二切割系统鼓轮积胶滞后、水松纸拼接断裂以及滤棒检测与缺棒堵搓板故障。通过对切割鼓轮结构、刀片厚度、水松纸拼接参数及滤棒输送系统进行系统分析，找出了造成故障的关键因素，包括切割槽间隙偏小、刀片厚度过大、拼接速度与磁条刮力度不匹配、滤棒沟槽阻力及负压吸风不足等。针对问题提出了四项结构优化与三项运行调整措施，并通过现场验证，显著提升了设备运行稳定性与生产效率，基本消除了积胶滞后与断纸故障。研究结果为卷烟机换牌适配与高效稳定生产提供了可操作的技术路径与维护标准。

Abstract

This study examines the operational performance of Hangzhou Cigarette Factory’s A2-type PROTOS-M8 ultra-high-speed cigarette machine after transitioning from soft red long nozzles to soft long nozzles. The analysis identifies three major operational issues during the adaptation to new auxiliary materials and structural modifications: delayed adhesive buildup in the rear cutting system’s drum wheel, water-soluble paper seam breakage, and filter rod detection failures with subsequent rod blockage on the rubbing plate. Through systematic evaluation of the cutting drum wheel structure, blade thickness, water-soluble paper seam parameters, and filter rod conveying system, the study identifies key contributing factors including narrow cutting slot clearance, excessive blade thickness, mismatched seam speed and magnetic strip scraping force, filter rod groove resistance, and insufficient negative pressure suction. Four structural optimization measures and three operational adjustments were implemented, with field validation demonstrating significant improvements in equipment stability and production efficiency, effectively resolving adhesive buildup delays and paper seam breakage. The findings provide actionable technical pathways and maintenance standards for brand adaptation and efficient, stable cigarette machine production.
