wtc-jsp distributed belt scale batching system (batching scale) developed by weikek company is the product of the combination of computer technology, control technology, communication technology and graphic display technology. its control function is perfect, the display and operation are centralized, the data processing is convenient, the installation and maintenance are simple, and the system is easy to expand. fully applicable to the high degree of automation of modern industrial production and the increasing complexity of process control. The system is widely used in metallurgy, coking, chemical, sintering, pellet, mineral processing, building materials, light industry, cement, food, fertilizer and other industries. Working principle: The disk feeder or other upper conveyor conveys material to the single machine belt scale, the weight signal of the single machine belt scale, the speed signal enters the accumulator, and it is processed and displayed inside the accumulator. At the same time, the output of the 4~20mA current signal proportional to the flow rate is all intelligent regulator, and the regulator outputs the 4~20mA current to the motor controller according to the PID parameters set by the user, and adjusts the speed of the feeder to achieve the purpose of controlling the feed quantity. The upper computer sends the ratio to each regulator through the RS485 interface, and reads the accumulator's accumulator's weight and flow rate into the machine to build the library, display, print and so on. System composition: The batching system is mainly composed of field production equipment, single machine belt scale (including conveyor system, belt scale body, weighing instrument, weighing sensor, speed measurement sensor equipment), regulator, frequency conversion controller, PLC, electric control cabinet, upper computer, system software and material level detection device. Key features of the system: The good measuring performance of weighing feeder provides accurate and stable basic data for the system.
