纸纱复合袋糊底机贴阀控制系统设计与实现

目的设计一套稳定性好、贴阀精度高、效率高且具有连续性的纸纱复合袋糊底机贴阀控制系统,解决目前国内贴阀系统贴阀不连续且贴阀精度不高的问题。方法贴阀控制系统采用连续性贴阀控制方案,与自动化糊底设备相配合,利用PLC高速脉冲输出控制伺服电机的速度,同时用高速计数器对增量编码器反馈的信号进行脉冲计数,最终完成对贴阀的精准控制。结果通过对贴阀系统进行测试,在阀口位置误差允许范围内,贴阀的合格率可达97.9%。结论通过对伺服电机的速度和贴阀位置的精准控制,贴阀控制系统的连续性、稳定性、贴阀精度和效率都得到了有效提高。

Design and Implementation of Valve Pasting Control System for Paper and Yarn Compounding Bag Bottom-pasting Machine

The work aims to design a set of valve pasting control system for paper and yarn compounding bag bottom-pasting machine with good stability, high valve pasting accuracy, high efficiency and continuity, to solve the problem that the current domestic valve pasting system is not continuous and the valve pasting accuracy is not high. The valve pasting control system adopted the continuous valve pasting control scheme, to match the automatic bottom-pasting equipment. The servo motor speed was con-trolled by the high-speed pulse output based on PLC, and the pulse counting of signals fed back by the incremental encoder was done with the high-speed counter; finally, the valve pasting was precisely controlled. After the valve pasting system was tested, within the allowable range of valve port position errors, the percent of pass of valve pasting could reach 97.9%. Through the precise control of the speed and valve pasting position of the servo motor, the continuity, stability, valve pasting accuracy and efficiency of the valve pasting control system are effectively improved.
