Mixing scales are automated production lines for conveying, proportioning, heating, mixing and finishing different types of materials. It controls the action commands of each part of the dosage so as to fully automate the process of material conveying, precise proportioning, mixing, blending and transportation. Through the material conveying device, all kinds of materials will be automatically conveyed to the dosing tank, and then automatically weighing according to the proportion, and then automatically conveying the proportioned mixture to the reaction kettle for stirring and mixing, and then automatically unloading the materials after stirring and mixing.
020-34563445Mixing scale combines 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. In the structure of the computer centralized control system to solve the "danger of centralized" problem, to achieve "centralized management of the danger of decentralization", the system is stable and reliable to meet the use of continuous production process.
The mixing scale adopts industrial PC as the upper computer (industrial computer, fully compatible with ordinary computers, more adaptable to the harsh industrial environment) + PLC + weighing module (or weighing signal sampling board) + 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.
Mixing scale application configuration software to complete the data acquisition and process control support a variety of communication protocols to provide users with a variety of equipment support, colorful dynamic screen and the system's powerful features, so that you can easily operate, with a strong scalability, easier to integrate with other systems, and more effective protection of the user's investment. The redundant station utilizes two redundant CPUs, which improves higher availability and security. According to the principle of one out of two, the switch automatically switches from the running system to the other in the event of a failure. This makes it possible for single-station systems to be combined with dual power supplies or industrial Ethernet communication modules for each subsystem. Safe, reliable and advanced and practical system design chooses the mature and advanced distributed computer control system to decentralize the dangers and improve the reliability of the system under the premise of centralized management of information and scientific operation in the production process, collects all kinds of data on the site with PLC and transmits them to the central control room for centralized monitoring and management through high-speed network, and the mainframe of the central control room also transmits the control commands through the high-speed network to the The host computer in the central control room also transmits control commands to the PLC measurement and control terminals through high-speed network to implement decentralized management of each unit.
It has the following advantages:
(1)The whole system adopts centralized structure, good openness, easy to expand, stable and reliable performance" structure mode: "upper computer + PLC system + solid dosage control instrument", the connection of each part of the equipment adopts 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)The computer monitoring and management of weighing and Batching system is powerful, real-time collection and timely display of operating conditions and relevant data, with realistic image and strong sense of dynamics; it can automatically complete the system batching process, and the computer screen real-time display of weighing and batching control system workflow, with simple software operation and realistic picture.
(4) High reliability of the product, the upper computer software set up to run the password and important parameters of the password to modify the protection, and the user to achieve hierarchical management, you can arbitrarily define the rights of personnel. Intelligent reporting software for production management to provide a large amount of data information, such as dosage results list, raw material consumption list, the production volume list, the formula to use the results of the record, etc., can be by 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 operating modes;
