Quality monitor soft sensing method based on rubber mixing process

Abstract

The invention discloses a quality monitor soft sensing method based on a rubber mixing process. An upper subsidiary engine, an automatic sampling system, a quality inspection system and a Mooney viscosity on-line automatic measurement model on a rubber mixing production line are automatically associated; the automatic sampling system carries out quality inspection sample acquisition on a current production train number and transmits the sample to the quality inspection system to obtain rheological parameters required; current rheological parameters are transmitted to the Mooney viscosity on-line automatic measurement model, and a Mooney viscosity value ynew is automatically output according to f: x->y; the Mooney viscosity value ynew is read out and transmitted to the quality inspection system, which will carry out corresponding technical adjusting on mixing process of a subsequent train number, according to contrast of the Mooney viscosity value ynew and a preset Mooney viscosity value scope, so as to automatically detect whether a new production task is for the production line. The invention saves a large amount of costs on purchasing and maintaining a Mooney viscometer and avoids huge labor and material resources required by a traditional Mooney viscometer measurement method.

Description

technical field [0001] The invention relates to a quality real-time monitoring method in the field of rubber tire manufacturing, in particular to a soft measurement method for quality monitoring based on a rubber mixing process. Background technique [0002] With the sharp increase of international and domestic rubber production, the continuous innovation of rubber product manufacturing technology, the mixed production of rubber materials with various formulas has also been popularized and promoted. In order to ensure the quality of rubber products and increase market competitiveness, the production process of rubber products must be strictly controlled. The mixing process is the first stage of rubber production, which directly affects every subsequent process, so real-time automatic control should be implemented on this process to ensure its quality requirements. However, one of the most important parameters for measuring the quality of a compound is the Mooney viscosity, ...

Problems solved by technology

[0010] After the above five steps, the Mooney viscosity value of the rubber compound for this trip can be measured, which is time-consuming and laborious. At the same time, there are still the following technical deficiencies and measurement defects:

[0014] Therefore, the hysteresis and uncertainty of the Mooney viscosity value detection is the bottleneck problem that restricts the quality tracking and process improvement of the existing rubber mixing production
