摘要
为解决片烟装箱翻包机在翻包过程中，翻转体出现抖动，且液压油温及驱动电机机壳温度偏高等问题，采用基于先验知识的LS-SVM（LeastSquaresSupportVectorMachines）理论，对皮带输送机定位方式进行了优化。利用PLC编程对翻转体控制系统进行改进，采用轴流风机和压缩机制冷技术对电机和液压油分别进行冷却处理，重新调整液压系统的工作压力。结果表明：改进后消除了液压缸向外渗油和翻转体抖动现象，翻转体对油缸活塞杆支撑区域出现的开裂现象由3～4次／年减少为0，电机机壳温度由65℃降至44℃，液压油温由55℃降至37℃左右，有效降低了设备故障率，提高了设备运行的可靠性和安全性。
As a solution to the dithering of turnover body and high temperatures of hydraulic oil and driving motor, the positioning means of belt conveyor was optimized by a prior knowledge based LS-SVM （Least Square Support Vector Machine） theory. The control system for turnover body was improved by PLC programming; motor and hydraulic oil were cooled by axial flow fan and compressor refrigeration technology respectively; and the working pressure of hydraulic system was readjusted. The results showed that after improvement, the leakage of hydraulic oil and the dithering of turnover body were eliminated, the cracking in the supporting area of turnover body to the piston rod of oil cylinder decreased from 3-4 times/year to 0, the temperature of motor lowered from 65 to 44 ℃ and that of hydraulic oil lowered from 55 to 37 ℃. The failure rate of equipment was effectively reduced, while the reliability and safety of equipment running were promoted.
