B1包装机组废烟剔除输送电控系统的改进

摘要

为解决B1包装机组废烟剔除输送系统电机的空转运行导致的电机和输送皮带使用寿命短等问题,对原控制电路进行了改进.未升级的B1包装机组电控系统,利用采样剔除阀输出的控制信号触发延时继电器的线圈,从而对电机的启停进行控制;已升级B1包装机组电控系统,通过修改PLC程序改进剔除输送系统.改进后有效提高了B1包装机组剔除输送系统的有效作业率,输送皮带磨损率、电机损坏率、电能消耗量均减少为改进前的1/17,备件使用周期延长,输送皮带使用寿命由原来的1个月延长至1年以上,减少了维修时间和维修频次,保证了机组的正常运行.%To solve the problem of short working life of motor and conveying belt caused by idle running in the defective cigarette rejecting and conveying system in Bl packing line, the control circuit was improved.In the original design, the motor was controlled by a delay relay which was triggered by the control signals from the sampling and rejecting valve triggering the coil of delay relay.In the upgraded control system, the rejecting and conveying system was improved by modifying PLC program.After improvement, the efficiency of rejecting and conveying system was increased, and the wear rate of conveying belt, motor damage rate and power consumption was only one seventeenth of the original ones.The working life of conveying belt prolonged from a month to more than a year, maintenance time and frequency were reduced as well.
