The weighing and discharging system will reflect the running status of loading, batching, feeding and related equipment in the form of dynamic pictures according to the actual process of batching technology. When there is an over-limit fault during operation,  will appear Chinese character alarm warning, and start the alarm (sound and light), or stop the machine, or change the warehouse, and analyze the control status of the operation data. The dynamic batching process of the system is reflected by different color histogram.

The reaction pot control system sets the discharge amount of each material through the weighing controller, and stores the formula. After pressing the START key, the PLC will issue the feeding instruction, and the feeding will start at this time. The valve of the middle metering hopper will be closed, the material will fall into the metering hopper, and the valve of the liquid material hopper will be opened. PLC issued a stop feeding instruction, at this time to stop the operation.

In order to ensure the accuracy of dosage, the reaction tank control system uses frequency converter to control the screw feeding speed so as to achieve the purpose of accurate dosage, and sets the dosage ratio through the two-way communication between the computer and the meter, and the serial port communicates with PLC. According to the actual process of dosage technology to reflect the dynamic screen in the form of loading, dosage, feeding and related equipment operating state, according to the operating data can be given to the ratio or feeding amount, and truly reflect the dosage state, the ideal equipment for continuous dosage and measurement of materials.

The reactor control system controls the dosing according to A certain proportion, at the same time gives the feeding system according to the material level information of each reaction tank, sets the relationship between the ratio of raw materials and the arrangement sequence of the total feed quantity meter, sets the weight of the equipment under each reaction tank through the communication of the upper computer, and sends the weight signal and speed signal to the weighing instrument after the weighing system is started. Instantaneous flow and accumulation are calculated and displayed in the field weighing instrument. Self-tuning operation is carried out according to the parameters set by the user. If there is a deviation between the set value and the current value, the PLC analog module will adjust according to the need.

The lubricating oil dosing system realizes PLC on-line control, the valve position and discharger position signal detection adopts load sensor, and the bin location adopts heavy weight type material level meter, which can realize continuous warehouse location detection. The control unit is mainly a touch screen, PLC as an auxiliary control system, man-machine interface display ratio parameters (formula) and monitoring and recording real-time data. According to the speed of weighing material, the lead amount is provided. When the weight is detected to reach the set value, the lead amount is subtracted, and the control instrument closes the feed valve. The lead amount can be manually corrected or automatically corrected, so that the control instrument can control the batching precision of each batching scale to reach the set target value.

The automatic control system of the reactor is composed of automatic batching design, feed and discharge all controlled by computer, dynamic weighing module, precision amplifier, A/D converter, microcomputer, monitor, printer and execution system. The weight required for various materials is set through the touch screen, and automatically transported to the ingredients in order for automatic weighing and flow control, so as to achieve accurate measurement and batching.

The anti-roll weighing sensor is accumulated through the junction box and transmitted to the weighing instrument, which displays the weight of the material in the current weighing in real time through A/D conversion. The displayed weight data is transmitted to PLC through serial communication, and the PLC compares the collected weight of the weighing module with the weight set in the touch screen (or computer) of the electronic scale to control the action of the whole reaction kettle. It adopts high-performance configuration software, has a complete Chinese interface, and has real-time data display, flow and temperature control curves, alarm and operation records, complete production reports and other management functions.

Liquid filling machine is mainly composed of filling management, metering and transmission control modules. Profibus system configuration, with PLC controller as the main station and ET200 distributed I/0 as the slave station, to realize the control of electronic scale, frequency converter and centrifugal pump, and to monitor the liquid level of each barrel and the manipulator. Complete the status monitoring, alarm display and manual operation of the metering and conveying process.

The automatic feeding system has very powerful functions to deal with the packaging process, set the target weight of any package, remove the tare automatically, correct the error automatically, and control the feeding actuator with multi-speed output and have the function of prohibiting the sampling time setting to eliminate the influence of the hopper vibration and rushing material on the metering accuracy, and the function of alarming for exceeding the difference in output, etc. It is equipped with a variety of communication interfaces to communicate with the upper computer, and is equipped with the corresponding operation software. It can be conveniently connected to the central control system of complete sets of production lines. Through the frequency conversion (service) control technology, running in the rigorous logic program of the programmable logic controller (PLC), so that the operation process becomes intelligent, reliable and stable; so that the manual operation becomes very simple.
