目的 解决YB28封签喷涂系统旋转故障、零件损坏较多、气马达故障和胶枪堵塞等问题。方法 通过故障统计分析原有结构的缺陷，设计一种双路封签冷胶喷涂系统，封签胶枪进入工位采用直进式运动替代旋转运动，基于主传动轴编码器相位信号进行封签涂胶，设计双喷嘴与封签喷枪的喷射角度，确保喷涂均匀，改进胶桶供胶管路及搅拌器装置，降低供胶管路堵塞风险，新增胶桶搅拌工作指示灯并将搅拌电机接入YB28控制系统，设备停机时喷嘴清洁装置对胶枪清洁密封。以生产“玉溪(软)”的ZB28软盒包装机组为测试对象，进行封签双路喷涂系统改进后试验，结果 改进后线束断裂次数减少了50%，胶路堵塞次数减少了62.5%，搅拌器失效次数降低了92.9%，设备效率提升了1.1%。结论 双路封签冷胶喷涂系统投入使用后，降低了维修频次和时间，提高了卷烟包装效率和产品质量。

The work aims to solve the problems of rotation failure, serious part damage, air motor damage and glue gun blockage in the YB28 spraying system. By analyzing the original structure malfunction through failure analysis, a dual cold glue spraying system for stamp was designed. The glue gun adopted straight motion instead of rotary motion when entering the station and then sealed and glued the label based on the phase signal of the encoder of the main drive shaft. The spraying angle of dual nozzles and spraying gun was designed to ensure uniform spraying and the rubber tube supply pipeline and agitator device of rubber barrel were improved to reduce the risk of blocking the rubber tube supply pipeline. A new indicator for mixing was installed in the rubber barrel, and the agitator motor was connected to YB28 control system. When the device stopped, the nozzle cleaning device cleaned and sealed the glue gun. Taking the YB28 soft box packaging machine for producing "Yuxi Ruan" as the test object, experiments were conducted on the improved dual stamp spraying system. After the improvement, the breakage number of wire harness was reduced by 50%, the number of glue blockage was reduced by 62.5%, the number of agitator failures was reduced by 92.9% and the efficiency increased by 1.1%. After the dual cold glue spraying system is put into use, the maintenance frequency and time are reduced and the packaging efficiency and quality of cigarette are improved.
