Problems solved by technology

Since the rubber production process is a typical intermittent process, the quality of the product is greatly affected by the process and the environment. Usually, the model established at one time cannot complete the real-time monitoring of the quality of the entire production process, which will seriously affect the quality of rubber products. There are strong obstacles to the reprocessing of rubber products, which will eventually affect the quality and life of the product, and there may be safety hazards, causing losses to enterprises and product users

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] In order to improve production efficiency and product quality, and realize online automatic measurement, the embodiment of the present invention provides an online measurement method for rubber hardness, see figure 1 , see the description below:

[0027] Rheological parameters of rubber quality indicators (mainly including minimum torque ML, maximum torque MH and vulcanization time parameters TC30, TC60 and TC90) are parameters that must be measured for each vehicle of rubber after mixing, and each measurement only needs 2 to 5 hours. Minutes, quick and easy detection. Considering the similarity in the working principles of Shore hardness testers and rheometers, and the strong correlation between rheological parameters and hard...

Abstract

The invention discloses an online rubber hardness measurement method, which includes updating an online hardness forecasting model f:x--y once the number of a new sample Xnew used for model updating reaches the threshold A; keeping the online hardness forecasting model without updating when the number is less than the threshold A, acquiring the updated online hardness forecasting model when the number reaches the threshold A, forecasting the rubber hardness value corresponding to the new sample Xnew of the next batch according to the updated online hardness forecasting model, and acquiring the error by acquiring the difference between the rubber hardness value and the actual measured rubber hardness value. By updating the online hardness forecasting model continuously, precise rubber hardness value can be acquired, and rubber quality is improved. According to tests, higher precision can be achieved while potential safety hazards can be reduced by using the online rubber hardness measurement method.

Description

technical field [0001] The invention relates to the field of rubber tire manufacturing, in particular to an online measurement method for rubber hardness. Background technique [0002] In recent years, with the increasing demand for rubber in production and life, the rubber industry has developed by leaps and bounds. Coupled with the continuous development of China's automobile industry, it has played a huge role in promoting the rubber industry. No matter in the field of production or life, more and more rubber products are used. The continuous emergence of new products and the continuous expansion of application fields have put forward newer and higher requirements for the production of rubber products. [0003] Rubber mixing is one of the most important processes in rubber production, and the effective control of the rubber mixing process directly affects the quality of rubber products. Rubber mixing is a typical batch process with obvious time-varying characteristics ...
