摘要
为提高饲料粉碎系统的生产效率与粉碎均匀性,本文设计了一种基于PLC控制的自动变速叶轮喂料器。机器由机架、叶轮、通风组件、磁吸装置、电机、上料口及PLC控制系统构成。该控制系统通过传感器实时采集粉碎机运行电流,并依据设定区间自动调节电机转速,实现喂料速率的闭环控制;同时对粉碎机的电流异常与温度异常进行蜂鸣报警,保障设备安全运行。本文对叶轮结构进行排布优化,计算得额定喂料速度为36.5 t/h,并采用SolidWorks Simulation对叶轮轴在堵料工况下进行静力学分析,结果表明最大应力为6.479×10^(7) N/m^(2),最大位移为0.02053 mm,均远小于45号钢的屈服强度,满足安全运行要求。研究表明,该系统具备良好的自动调节能力与结构可靠性,可有效提升粉碎作业的连续性与智能化水平。
To improve the production efficiency and crushing uniformity of the feed crushing system,this paper designs an automatic variable-speed impeller feeder based on PLC control.The machine is mainly composed of a frame,impeller,ventilation components,magnetic suction device,motor,feeding port,and PLC control system.The control system collects the operating current of the crusher in real time through sensors,automatically adjusts the motor speed according to the set interval,and realizes the closed-loop control of the feeding rate.At the same time,it gives a buzzer alarm for abnormal current and temperature of the crusher to ensure the safe operation of the equipment.In this paper,the impeller structure is arranged and optimized,and the rated feeding speed is calculated to be 36.5 t/h.Solidworks Simulation is used to carry out static analysis on the impeller shaft under the material blocking condition.The results show that the maximum stress is 6.479×107 N/m 2,and the maximum displacement is 0.02053 mm,which are far less than the yield strength of 45#steel,meeting the safety operation requirements.The research shows that the system has good automatic adjustment ability and structural reliability,which can effectively improve the continuity and intelligence level of crushing operations.
