基于西门子PLC的双闭环PID控制在橡胶制品挤出上的应用

Application of Siemens PLC-based double closed-loop PID control on rubber products extrusion

现有轮胎生产技术中,轮胎产品中的主要半制品橡胶部件需要采用挤出工艺进行生产,半制品挤出过程是生产汽车轮胎必不可少的工艺环节,挤出制品的质量与精度直接影响到轮胎产品的最终质量与精度,也影响到轮胎生产的成本。解决稳定性差,挤出精确性差问题迫在眉睫。本文论述的控制系统采用一种串联双闭环PID算法进行速度的闭环控制,能够较好的解决现有轮胎半制品挤出生产技术中稳定性差和挤出精确性差的问题。

In the existing tire production technology,the main semi-finished rubber components in tire products need to be produced using extrusion technology.The extrusion process of semi-finished products is an essential process in the production of automotive tires.The quality and accuracy of extruded products directly affect the final quality and accuracy of tire products,as well as the cost of tire production.It is urgent to solve problems such as poor stability and poor extrusion accuracy.The control system discussed in this article adopts a series double closed-loop PID algorithm for speed closed-loop control,which can effectively solve the problems of poor stability and extrusion accuracy in existing tire semi-finished product extrusion production technology.
