基于电子凸轮与伺服电机的壁厚控制装置

Wall Thickness Control System Based on Electronic Cam and Servo Motor

针对吹塑制品的壁厚不均匀问题,对塑料挤吹机的挤出型坯壁厚控制系统进行研究。系统采用电子凸轮与伺服电机来控制壁厚,完成壁厚控制凸轮人机交互式界面和电子凸轮软件的开发,并对伺服电机控制机械装置进行了具体的方案设计及结构设计,装置运动响应快,控制精度高。研究结果在企业投入实际应用,取得了很好的效果。

Aiming at the problem of blow molding products＇ uneven wall thickness, squeezing extruded embryo＇s wall thickness control system of blowing machine of plastic was researched. The system adopted electronic cam and the servo motor to control the wall thickness, and completed the development of wall thickness control cam man-machine interactive interface and the electronic cam software. The scheme and detailed structural design of the servo motor control mechanical device was deseigned. The device possesses fast response of movement and high control precision. The research results are applied in enterprises, and achieve good effects.
