Method and system for dynamic adjustment of temperature in a silica gel baking channel

Abstract

The present application belongs to the technical field of rubber product production control, and particularly relates to a silicone oven temperature dynamic adjustment method and system, comprising the following steps: S1, collecting multi-dimensional state data in the oven production process, the multi-dimensional state data including the real-time sag value of the silicone strip in the oven, the real-time tension applied by the traction machine, the traction speed and the real-time environmental temperature in the oven; S2, calculating the rheological impedance index representing the current curing state of the silicone according to the change rates of the real-time tension, the traction speed, the real-time sag value and the real-time environmental temperature, the rheological impedance index being positively correlated with the real-time tension and negatively correlated with the real-time sag value. The present application can not only monitor the physical form of the product in real time, but also solve the problem of traditional PID control lag through a nonlinear aggressive compensation strategy, and can significantly improve the size accuracy of soft rubber products such as silicone tubes and sealing strips, and eliminate the waste caused by gravity deformation.
