Speed regulation Automatic batching system A common weighing device that uses negative pressure to attract material into a weighing device for weighing. It can effectively improve production efficiency and product quality. During the weighing process, the pressure inside the container is lower than the external atmospheric pressure, so the material is attracted into the weighing container. When the material reaches the set weight, the weighing container will automatically stop attracting and complete the weighing process.
020-34563445The speed-regulating automatic Batching system consists of an industrial management system, a PLC electrical control system, and N single-loop closed-loop control circuits. Each closed-loop control loop consists of a screw conveyor, a weighing display, a weighing sensor, a frequency converter and a field control box. And a communication interface with the host computer is reserved. The weight signal is sent to the speed-regulating hopper scale and the weighing instrument. The weighing instrument calculates and processes the load weight signal to obtain the weight of the material, which is displayed respectively on the weighing display.
The weighing instrument and the variable frequency speed regulator control the rotational speed of the screw conveyor to form a closed-loop control. The intelligent software regulator built into the weighing instrument can set high, medium and low feeding levels to ensure the accuracy of batching. Three sets of signals are output to control the frequency converter, which in turn controls the feeding speed of the screw Feeder, thereby achieving the purpose of precise batching. The weighing instrument can manually set the feeding amount, or the proportion can be set through two-way communication between the computer and the instrument. Communicate with the PLC through the serial port. The industrial control computer reflects the operation status of feeding, batching, feeding and related equipment in the form of dynamic pictures according to the actual process of batching technology. When an over-limit fault occurs during operation, a Chinese alarm prompt will be displayed, and the alarm (sound and light) will be activated, or the machine will be shut down, or the warehouse will be changed. A control status analysis can be made based on the operation data. The dynamic batching process of the system is reflected by different color bar charts. Based on the operation data, the industrial control computer can issue the proportioning or feeding quantity and truly reflect the batching status. It also has other functions, such as shift reports, daily reports, monthly reports, annual reports, etc. It provides convenience for management.
