Sizing percentage consistency control method suitable for coating rubber parameters of different squeezing rollers

Abstract

The invention relates to a sizing percentage consistency control method suitable for different squeezing roller coating rubber parameters, and high-precision control of the sizing percentage in the sizing process is realized by constructing a mechanism model of influence of squeezing roller coating rubber layer parameters and squeezing force on the sizing percentage. The method comprises the following steps: constructing an influence relation model of a squeezing roller coating rubber parameter and a grouting force on the sizing percentage according to the influence mechanism of the squeezing roller coating rubber parameter and the grouting force on the sizing percentage; determining model parameters of the influence relation model according to the thicknesses, the hardness and the mud jacking force of different mud jacking roller coating rubber layers and the corresponding sizing rates; and according to the determined model parameters and in combination with the influence relation model, determining an optimal grouting force set value with a specific sizing percentage as a target under the current parameters of the coating rubber of the grouting roller. By means of the control method, stable control over the sizing rate of the squeezing rollers with different coating rubber layer thicknesses and hardness can be achieved, and the sizing efficiency and the sizing quality are further improved.
