[0002] As is well known, the process requirements in tire rubber compounding directly affect tire quality. Therefore, real-time monitoring of each batch of rubber compound production can better control the quality of the compound. The auxiliary equipment system monitors data such as temperature, power, and time at various stages of the masterbatch rubber compounding process, generating curves from the data at each time point. Manual analysis compares these curves with a standard curve to determine whether the production process meets the process requirements. Existing methods for determining this have the following problems:

[0003] The masterbatch mixing operator can only passively adjust the parameters during the mixing process according to the prompts given by the auxiliary equipment; the real-time and historical curves of the masterbatch compound mixing need to be viewed in the auxiliary equipment system; when the masterbatch compound has quality abnormalities, the curve data needs to be copied from the auxiliary equipment system, which affects the data security of the auxiliary equipment; the masterbatch compound mixing curve includes multiple parameters such as time, power, and temperature, which is difficult to judge manually. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an automatic determination method for the mixing curve of masterbatch rubber compound for all-steel radial tires, which can realize the automatic determination of the mixing curve of masterbatch rubber compound.

[0005] The technical solution adopted by this invention to solve its technical problem is: an automatic determination method for the mixing curve of a first-stage masterbatch rubber compound for all-steel radial tires, comprising a production information system, an auxiliary machine PLC system, an auxiliary machine PC, a database, a production information system client PC, and alarm lights. Its features are: the auxiliary machine PLC system controls the production of the rubber compound; the production information system acquires data from the database of the auxiliary machine system; the production information system automatically determines the mixing curve of the rubber compound; and the production information system controls the alarm lights to sound an alarm. The production information system maintains the standard parameters for the mixing of all rubber types; the auxiliary machine PLC system acquires the data of the rubber compound mixing process on site; the auxiliary machine PC control system displays the mixing data curve from the auxiliary machine PLC system; the production information system acquires the real-time mixing data from the auxiliary machine PLC system, generates a real-time curve graph with a standard curve comparison, and marks abnormal points and their causes; displays the comparison curve graph on the production information system client; and the alarm lights sound an alarm for abnormalities.

[0006] The beneficial effects of this invention are that it automatically determines the mixing curve based on the standard mixing parameters of the rubber compound, monitors the curve at each time point, analyzes and marks each abnormal point in the mixing process in real time, and simultaneously alarms the auxiliary equipment and operating platform for abnormal data, thereby reducing the time and labor costs of manual judgment, reducing the risk factor of data copying in the auxiliary equipment system, reducing the scrap rate of masterbatch production, and effectively improving the quality and yield of masterbatch.
