Automatic batching machine according to the test data for formula calculation, through the human-machine interface or computer network input to the computer system, the computer control system according to the test data and process formula automatically calculate the supply of raw materials ratios, and then by the PLC control system integrated supply of raw materials supply system supply speed in accordance with the order of the process of accurate and continuous completion of the raw material ratios. Mixer to raw material composition, auxiliary components and other groups of parameters as the basis for calculation, combined with the actual production of the data required to calculate the specific production process design. The system software includes sub-systems such as raw material composition input and dosage calculation. The Weighing system adopts ORACLE database system and c# language for design and realization, which is successfully applied to the batching site under the guarantee of calculation accuracy and interface beauty and convenience.

Weighing and Dosage system with industrial PC as upper computer (industrial computer, fully compatible with ordinary computers, more adapted to harsh industrial environments) + PLC + weighing module (or weighing signal sampling board) + load cell + weighing actuator. It can contain measurement control host (host computer), weighing software (measurement software/control software), plc weighing control instrument, load cell, weighing bin also known as bucket scale, bin scale, the way can be incremental and decremental scales); and most of the cases are controlled by frequency converter.

The weighing and dosing system is also composed of an industrial computer, a PLC programmable controller, a powder dosage system, a liquid dosage system, a micro dosage system and a control system. This weighing and dosing control system is an automatic weighing system with vacuum feeding, dosing screw quantitative dosing, weighing hopper automatic weighing and dosing, and cumulative weighing at the same time. It is suitable for precise measurement of materials and automatic dosage in the production process.

According to the characteristics of the industry, the requirements of the production process, the specific characteristics of the material, can be reasonably selected "incremental" or "decreasing" and other weighing methods, with a single hopper single material, a single hopper multi-material, multi hopper multi-material and other modes of operation.

Automatic dosage systems offer the following advantages:

(1) The whole system adopts the hub-and-spoke structure, good openness, easy to expand, stable and reliable performance" structure mode: "upper computer + PLC system + solid dosage control instrumentation", each part of the equipment is connected using RS485 field bus, the structure is simple and reliable.

(2) The weighing instrument adopts high-quality controller, which is characterized by high precision, high reliability and strong anti-interference ability. The load cell adopts high-precision weighing module. The weighing module is easy to install and maintain.

(3) weighing and Batching system using computer monitoring and management of powerful, real-time collection, timely display of operating conditions and relevant data, the picture image is realistic, strong sense of momentum; can automatically complete the system batching process, the computer screen real-time display of the workflow of the weighing and batching control system, the software is simple to operate, the picture is realistic.

(4) The product is highly reliable, the upper computer software is set up to protect the running password and important parameter password modification, and the user realizes hierarchical management, which can arbitrarily define the authority of personnel. Intelligent reporting software for production management provides a large amount of data information, such as dosage results list, raw material consumption list, production volume list, formula use results records, etc., according to time, formula and other production shift report, daily, monthly and annual reports and other statistical and printing functions.

(5) Fault response is accurate and timely, can automatically display or print the time, nature and location of the fault, and sound and light alarm; control mode can be divided into remote automatic, local automatic, local manual and local instrument control and other modes of operation;
