Description
Technical Field
The invention provides a method and equipment for detecting a rubber sample identifier for rubber mixing production, in particular to a method and equipment for tracking and detecting key performance parameters based on an RFID information reading mode, and belongs to the field of rubber machinery and automatic production control.
Background
With the continuous innovation of rubber manufacturing technology, the mixed production of rubber materials organized into various formulas has become popular. In order to improve the quality in the mixing process, and improve the dispersibility of the auxiliary agent and the overall uniformity of the rubber material, a plurality of continuously produced rubber materials of the train number are positioned, sampled and inspected to judge the quality of the mixed rubber so as to obtain data support for improving raw materials, rubber mixing process and rubber material stability. And (4) judging key parameters of rubber mixing quality, such as detection items of the rheology, the Mooney viscosity, the scorch, the hardness and the like of the rubber material.
For example, in the Mooney viscosity detection of rubber products in China at present, a laboratory Mooney viscometer is generally used for off-line measurement, the detection data delay is generally more than 8-10 hours, the quality control of a production field is delayed, and real-time information cannot be provided for process optimization and production quality improvement. And the field sampling mainly depends on manual experience to carry out timing and constant temperature sampling, the glue sample is marked in a handwriting mode, and the glue sample is sent to a quick detection position for detection processing after reaching a certain quantity. Because the field sampling equipment is simple and crude and the sampling means is laggard, the judgment error is easy to cause, and the larger error is caused, so that the verification reference function of sampling and submission is lost.
Moreover, the manual participation degree is large in the sample feeding detection process, and the continuously produced rubber material production process information of a plurality of car numbers is easy to generate errors or mix, such as the car numbers, operators, dates, rubber mixing time, working condition standards and other contents. Once errors occur, the error correction of the banburying production process can be directly influenced, so that the continuous quality problem is caused, the integral production energy consumption is increased, even scorching is caused, and the waste rubber is formed.
Therefore, how to ensure the timeliness and the accuracy of the detection data of the continuously produced rubber materials in multiple batches and improve the automation level of the operation of the whole internal mixing system by detecting the information feedback from sample feeding becomes an important restriction factor of the existing rubber mixing production.
Disclosure of Invention

The RFID electronic tag is used as a data information carrier, and the data information carrier is based on a computer network management technology, so that the data information carrier plays a role of an 'electronic identity card', an identification code with uniqueness can be completely stored in the RFID electronic tag, and the identification code can be transmitted/received, read and identified through a radio frequency signal processing terminal. Based on the RFID information reading mode, the glue sample is added with a unique glue sample in the whole sample feeding detection link and is distinguished from the glue samples of other train numbers or other processes.

In order to improve the utilization efficiency of the sample conveying device and shorten the sample conveying detection period, the following identification control method for placing a plurality of glue samples in the same train number in one sample conveying device can be adopted:
