YB28包装机三号轮故障维修技术改造

Technical Modification and Repair of the Faulty Third Wheel of the YB28 Packaging Machine

摘要: 为解决国产YB28包装机三号轮底部干燥装置加热片易损坏、干燥温度不稳定导致烟包小盒底部不粘、底部褶皱、底部粘贴处翘边等问题，对三号轮底部干燥装置进行了改进。设计了一种采用安装座导向板对商标纸底部进行折叠保持，内置加热内芯的安装座，其表面直接对烟包底部进行干燥的新型烟包底部干燥成型装置。内置加热内芯将安装座工作表面加热升温到50℃~60℃范围内；安装座导向板接过从商标纸第四折叠器出来的烟包，挡住商标纸底部不散开，直到烟包运行到安装座工作面；安装座工作面对烟包底部进行加热干燥；加热器温度由温度传感器检测、控制；安装座工作面与烟包底部的间距通过调整垫片及云母隔热板调整。以玉溪卷烟厂使用的YB28包装机为对象进行测试，结果表明，改造后烟包小盒底部缺陷率降低89.8%，不再需要更换加热片。该改造降低了设备停机次数，提高了YB28包装机的运行效率。

Abstract: In order to solve the problems of easy damage to the heating sheet of the bottom drying device of the No. 3 wheel of the domestic YB28 packaging machine, the unstable drying temperature leads to non-stickiness at the bottom of the cigarette pack box, the bottom fold of the bottom and the warping edge at the bottom paste, and the bottom drying device of the No. 3 wheel is improved. A new type of cigarette pack bottom drying molding device is designed by using a mount guide plate to fold and hold the bottom of the trademark paper, a mount with a built-in heating core, and its surface directly to the bottom of the cigarette pack. The built-in heating core heats the working surface of the mount to the range of 50˚C~60˚C; The mount guide plate takes the cigarette pack coming out of the fourth folder of the trademark paper, blocking the bottom of the trademark paper from falling apart until the cigarette pack runs to the working surface of the mount; The working base of the mount is heated and dried on the bottom of the cigarette pack; The heater temperature is detected and controlled by the temperature sensor; The distance between the working surface of the mount and the bottom of the pack is adjusted by adjusting the gasket and mica insulation board. The YB28 packaging machine used by Yuxi Cigarette Factory was tested and the results showed that the defect rate at the bottom of the cigarette pack box was reduced by 89.8% after the transformation, and the heating sheet was no longer necessary. The renovation reduced the number of equipment shutdowns and improved the operating efficiency of the YB28 packaging machine.
