石蜡油自动灌装装置的研发

Development of automatic filling device for paraffin oil

针对润滑脂生产过程中石蜡油的手动灌装工序费时费力,精度和实时性难以保证等问题,根据对工艺流程和现场布局分析,研发了一套能自动补料、称重和灌装的石蜡油自动灌装装置。该装置的机械结构以铝型材作基材,采用了上下式分布结构,集补料、称重和灌装工序于一体;设计了电气控制系统的架构,给出了系统硬件组成,编写了PLC的模拟量信息采集和称重控制器的通讯程序,并给出了相应梯形图和人机界面的组态。研究结果表明:该装置结构简单、运行平稳、灌装精度高,可大大提高润滑脂生产的自动化程度。

Aiming at the problems of time-consuming for laboring manual filling process of paraffin oil in the process of grease production, and difficulty in ensuring accuracy and real-time performance, an automatic filling device of paraffin oil that can automatically fill material, weigh and fill was studied, which based on the analysis of technological process and field layout. The mechanical structure of the device was made of aluminum profile as the base material, and the up-down distribution structure was adopted to integrate feeding, weighing and filling processes. PLC was adopted as the control system for electrical control, the structure of the control system was designed, the hardware composition of the control system to be raised. Based on PLC, the program of analog quantity information collection and communication with the weighing controller was compiled. The corresponding trapezoidal diagram and the configuration of man-machine interface were written. The results indicate that the device has the advantages of simple structure, smooth operation, high filling precision, greatly improves production automation.
