The Weighing dosing system is usually used for batch mixing of more than two kinds of raw materials in proportion, and the program control makes the batch mixing do continuous action, so as to achieve the uniformity of the mixing ratio performance. The human-machine interface is used to input the corresponding proportioning parameters, and the signal of each sensor is transmitted to the weighing instrument through the weighing module, and then the signal is converted by the weighing instrument and connected to the central controller, which, in combination with the set formula and according to the real-time data of each weighing unit, controls the dosing time and amount of dosing of each kind of material, and all the raw materials enter into the horizontal mixing machine after the weighing is finished.

The automatic batching system is used as a central control area to complete the whole process of weighing and feeding. Before the equipment is equipped, the staff will open the switch, and the PLC central control area will send a signal to start the corresponding solenoid valve to inject the material into the reactor. At the same time, the weighing module will start to work. When the amount of the reaction tank is increased to the equivalent of the weight set by the quantitative setting reference, the central control area receives the action signal of the weighing module, and immediately closes the solenoid valve for adding materials and stops adding materials.

The batching and weighing system is realized by using fuzzy adaptive PID control. The parameters of the controller are adjusted online to track the given input, accelerate the adaptive process and reduce the tracking error. Through the microcomputer to connect a number of weighing feeder, can be used for bin batching, at the same time batching materials can be up to 9 ~ 12, to carry out a variety of materials continuous batching, based on the structure of the bucket scale, can directly carry out the weight calibration, through the weighing hopper each moment test calculated the actual discharge amount, and then closed-loop adjustment, so as to achieve a higher control accuracy.

​The metering batching system consists of a central feeding hopper, loading and discharging valves, and control equipment. A flap is installed in the central feeding hopper to control the loading of the 1st and 2nd weighing hoppers. The material conveyed by the belt conveyor passes through the flap in the central feeding hopper and falls into the weighing hopper set at the lower limit. When the weight of the material in this weighing hopper reaches the upper limit (full), the weighing instrument of this hopper will output two signals to control the flap in the central feeding hopper to switch, transferring the material from the 1st weighing hopper to the 2nd weighing hopper.

Quantitative Batching system realizes intelligent and networked management of small material batching, so that finished products and raw materials can be traced in both directions, production decision-making and production control are seamlessly connected, production execution is improved, and real-time and accurate production data are used as the basis for managers' decision-making, so as to prevent the occurrence of quality accidents. Help customers to solve the dosage error prevention, improve dosage precision, quality traceability products, intuitive image, over the limit of the sound and light alarm prompts the application of bar code to effectively prevent the occurrence of the wrong raw materials raw material lot number bar code and finished product lot number bar code fixed in the bar code block can be reused.

The given batching system uses rotor pumps for feeding and automatic metering control. A weighing module is installed under the material tank to monitor the batching weight. When the added materials in the tank meet the formulation requirements, the feeding will be automatically stopped and the delivery will be automatically shut off. A closed-loop weighing system composed of a computer and a frequency converter speed regulator is used.

According to its specific production process and process equipment, the Stir reactor weighing can achieve stable product quality through automatic monitoring and control of production parameters such as temperature, pressure, flow rate and batching accuracy. After particle size, moisture, viscosity and other quality testing, in a specific temperature, sealed and other environment storage and transportation. The use of computer for online monitoring and management has higher requirements for weighing speed, weighing accuracy, system compatibility and scalability.

The weighing of the reaction tank is transmitted from the industrial computer in the control center to the electronic scale and PLC controller through the communication line, and the weight of each link is collected and displayed, and the fast feeding and slow feeding strategies are adopted in different weight stages to improve the efficiency and the measurement accuracy of the electronic scale. When the ingredients reach the target value, the output stop measurement signal, and the related valves and pumps are closed by PLC control. At the same time, the action of unloading the reactor is completed, and the measuring instrument is automatically zeroed and peeled.

Weighing the reaction pot by several raw material conveyor screw to the raw material in the order of the set to the metering scale, each raw material according to the automatic control system set the weight of the conveyor in turn, after the weight of the raw material is measured, and then by the metering scale of the discharge spiral to all the raw materials to the downstream equipment (cache bin, or direct pipeline connection), while starting the vacuum conveyor or valve. The raw material is sent to the waiting bin located above the main engine, where the weight of the raw material is completed.
