Abstract: 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.
Key words: relaxation extrusion; series double closed-loop PID control; stability; accuracy
