The automatic batching equipment is connected to the field weighing instrument through the bus, the control field equipment, the frequency converter of the weighing feeder, etc., which has a high degree of intelligence and fast processing speed. In the process of batching production, the main material and auxiliary materials are matched in a certain proportion to complete the measurement of the transported material. It is mainly responsible for real-time control of conveying and weighing process, fault detection, display and alarm, and adjustment of spiral speed by output signal to inverter.

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.

Weighing and discharging system in is an organic whole, storage unit, dosing unit, control unit is the three inseparable basic units, is to ensure that the flow of material dosing of the necessary conditions. The basic unit of material and conveying link in the material changes will have an impact on the flow. Batching control not only rely on the improvement of the regulating device and the optimization of the control software to continuously improve the quality of the dosage regulation, but also with the dosage process is inextricably linked to the dosage process, only from the dosage engineering point of view, in order to grasp the direction of the development of the dosage control, to meet the modern industrial automation of the requirements of large-scale production.

Reaction pot weighing system to be weighed after the start of the weight signal and speed signal to the weighing instrument, through the amplification of the A/D conversion, calculated instantaneous flow and cumulative amount, and displayed in the field weighing instrument. The indicator uploads the signals to the PLC module, the PLC analog input module collects the weight signals and speed signals from the screw and feeding device, and carries out the self-tuning operation according to the parameters set by the user, and the level weight of the materials in the reaction tank measured by the weighing module of the reaction tank regulates the flow rate of each downstream port of the dosage reaction tank, so as to guarantee the balance of the inlet and outlet of the mixing and storage tanks.

The distillation tank weighing system adopts a computer with stable performance to complete the data acquisition and communication processing, which is convenient to provide processing accuracy and cost reduction, and the data output and management are carried out through the COM communication interface of the computer itself; Mitsubishi F900 touch screen is chosen to replace the conventional weight indicator to do the human-machine interface, which makes the programming of the interface between PLC and weight indicator become simpler, and enables the display function to be enhanced. The weighing system is to add two or more kinds of materials to the mixing tank automatically according to a certain weight ratio, and then automatically discharges the materials after mixing to meet the predetermined requirements.

The weighing system of the reaction tank is transmitted to the central control room for centralized monitoring and management through high-speed network, and the host computer of the central control room also transmits control commands to the PLC measurement and control terminal through high-speed network to implement decentralized management of each unit. Integrating computer technology, automatic control, communication technology, weighing technology as a whole, its control function is perfect, display, operation is centralized, data processing is convenient, installation, maintenance is simple, the system is easy to expand.

Reaction kettle weighing system is a kind of production equipment used in industry for automatic and accurate proportioning of different powder or liquid materials according to a certain ratio, which usually consists of weighing instrument, PLC system and upper computer. Including raw material storage body, conveying body, weighing and dosage body, dust removal body, material mixing body and other equipment; dosage mode can be based on the industry characteristics, production process requirements, specific material characteristics, reasonable choice of "incremental" or "decreasing" weighing mode. It has various working modes such as single hopper and single material, single hopper and multiple materials, and multiple hoppers and multiple materials.

According to the predetermined formula, the measuring reaction tank will add a variety of materials into the weighing hopper according to the fixed proportion weight value. When the weighing is displayed to the amount, the materials will be discharged into the inlet of the mixing machine once or several times in steps according to the unloading procedure. It is also possible to control the weight and flow of the material loaded into the weighing hopper through the monitoring system and PLC program, so as to achieve accurate metering and batching. The system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.

The standard loading device is evenly distributed in the carrier (tank), and is connected with the bottom plate and the special force frame, and is connected with the control system. The hydraulic pump synchronously inputs the pressure from the divider to the cylinder, and the control force of the weighing control system ensures the balanced loading of the force and maintains the stability of the loading. The weighing sensor is affected by the force and reads the data through the weighing display. In order to realize the consistency of standard load values given by multiple groups of standard loading device units, the measurement module is used to feed the signal to the single chip microcomputer in real time, and the multiple groups of standard loading device units work synchronously.
