The weighing and loading device is sent to the weighing area through the screw, and the weighing sensor outputs a voltage signal according to the pressure of the material, which is amplified to output a metering level signal, which is proportional to the weight of the material. Then the signal is sent to the upper computer interface, and converted into a weight signal, the weight value is displayed on the current PC, and is sent to the PLC, which will compare and calculate the given value of the proportioning set by the PC. This control quantity is transmitted to the frequency converter and the output value of the frequency converter is changed to complete the control of the speed. Adjust the dosage to the same as the set value to complete the dosing process.
020-34563445Feeding system is a kind of production equipment used in industry to process different powder or liquid materials according to a certain proportion automatically and accurately, usually composed of Weighing system, weighing instrument, PLC system and upper computer.
Weighing and batching equipment includes a variety of equipment such as storage body of raw materials, conveying body, weighing and batching body, dust removal body and material mixing body;
Batching mode can be reasonably selected according to the industry characteristics, production process requirements, specific material characteristics, "incremental" or "decremental" weighing mode, with a single hopper single material, single hopper multi-material, multi hopper multi-material and other modes of operation.
The automatic Feeder can adopt advanced dosage control type weighing instrument, which can conveniently use ProFibus, MOD-BUS, Ethernet and other communication modes to complete the high-speed communication with PLC system, featuring strong real-time system, good reliability, flexible configuration and so on.
Feeding system performance characteristics:
Reliable system, strong applicability, high weighing precision, high automation precision, stable quality, easy to manage.
Electronic weighing display design, high metering precision, easy calibration and maintenance
Data processing, the batching machine can automatically operate and process the collected signals, so as to automatically control the normal operation of the equipment.
