The pre-set dosing plan of the Condensation weighing and mixing equipment automatically weighs various materials, automatically controls each link of dosing, and completes the dosing process. According to the amount of feeding, the speed of the motor is controlled. When the feeding value is close to the set value, the low-speed feeding mode is adopted. Due to the retention of materials in the air between the feeding port and the feeding tray, the motor stops rotating when the control lead is reached. When the actual batching process reaches the control lead amount, due to the difference in material density, the quality of the air material retained after the motor stops rotating is different, and the lead amount of the motor stop is set according to the actual operating condition.
020-34563445The condensing weighing and mixing equipment integrates computer technology, automatic control, communication technology and weighing technology. It has complete control functions, centralized display and operation, convenient data processing, simple installation and maintenance, and the system is easy to expand. Structurally, it has solved the problem of "concentrated danger" in the computer centralized control system, achieving "centralized management and decentralized danger". The system is stable and reliable, meeting the requirements for use in continuous production processes.
The weighing and batching equipment uses configuration software to complete data acquisition and process control, supporting multiple communication protocols, providing users with a variety of equipment support. Rich and colorful dynamic images and powerful system functions make it easy for you to operate. The Batching system has strong scalability, is easier to integrate with other systems, and more effectively protects users' investments. Redundant stations utilize two redundant cpus, enhancing higher availability and security. According to the principle of choosing one of the two, when a fault occurs, the switch automatically switches from the running system to the other system.
Under the premise of centralized information management and scientific operation in the production process, the batching control system disperses risks and enhances the reliability of the system. It uses PLC to collect various on-site data and transmits them to the central control room for centralized monitoring and management through a high-speed network. The central control room host also transmits control commands to the PLC measurement and control terminal through a high-speed network. Implement decentralized management of each unit.
An industrial PC is adopted as the upper computer (an industrial computer that is fully compatible with ordinary computers and more suitable for harsh industrial environments) +PLC+ weighing module (or weighing signal sample) + load sensor + weighing actuator. It may include a metering control host (upper computer), weighing software (metering software/control software), plc weighing control instrument, weighing sensor, hopper scale, and warehouse scale. The methods can be incremental scale and subtractive scale. And in most cases, it is controlled by a frequency converter.
The weighing and batching equipment has the following advantages
The entire system adopts a distributed structure, featuring good openness, easy expansion, and stable and reliable performance. The structural mode is: "upper computer +PLC system + solid batching control instrument". The connection of each part of the equipment uses RS485 fieldbus, which is simple and reliable in structure.
(2) The weighing instrument features high precision, high reliability and strong anti-interference ability. The load cell adopts a high-precision weighing module, which is easy to install and convenient to maintain.
(3) The computer monitoring and management function used in the weighing and feeding system is powerful, capable of real-time collection and timely display of operating conditions and related data. The picture is vivid and dynamic. It can automatically complete the batching process flow of the system. The computer screen displays the working process of the weighing batching control system in real time. The software operation is simple and the picture is realistic.
(4) The upper computer software sets the operation password and the password modification protection for important parameters. Moreover, users can achieve hierarchical management and arbitrarily define the permissions of personnel. Intelligent reporting software provides a large amount of data information for production management, such as ingredient result lists, raw material consumption lists, production volume lists, and records of formula usage results, etc. It also has statistical and printing functions for production team reports, daily reports, monthly reports, and annual reports by time, formula, etc.
(5) The fault response is accurate and timely. It can automatically display or print the fault time, nature and location, and issue audible and visual alarms. The control modes can be classified into remote automatic, local automatic, local manual and local instrument control operation methods, etc.
