Weighing dosing machine supports Microsoft's various networks, with simple networking and database functions. WINCC not only has its own database, but also supports SQL language, which can be easily connected with other databases. WINCC provides various powerful functions, which can meet various special requirements of users in operation, display and recording through configuration. Through transformation, the system can upload industrial process parameters, cost parameters, major and minor parameters, etc. to the management platform and auxiliary decision-making platform in real time through the information bus.
020-34563445The automatic dosing machine is mainly composed of welded and painted tubular steel, stainless steel, charging hopper with pneumatic closure, fast discharging channel, slow discharging channel with vibrator to achieve accurate weight, weighing hopper installed on weighing sensor, pneumatic device for locking empty bags, PLC operation interface and user-friendly keyboard. The dispenser can be combined with an electric conveyor belt for automatically loading products, a free or electric conveyor belt for unloading full bags of products, and an automatic packaging machine.
The automatic mixer calculates the formula according to the detection data and inputs it into the computer system through the man-machine interface or computer network. The computer control system automatically calculates the supply ratio of each raw material according to the detection data and the process formula, and then the PLC control system synthesizes the supply speed of each raw material supply system to accurately and continuously complete the raw material ratio according to the process sequence.
The weighing control system measures the speed of the spiral operation, converts it into corresponding pulse signals, and sends them to the computer after photoelectric isolation. The computer communicates with PLC to detect the flow rate and the running state of the feeding motor. After the instantaneous flow is calculated by the computer, it is compared with the required flow, and the computer outputs the corresponding speed regulating signal. After photoelectric isolation, DA is converted into a speed regulating signal of 4-20mA, and the operating frequency of the frequency converter is adjusted, so as to control the operating speed of the feeding motor and achieve the purpose of controlling the feeding amount.
The feeding system adopts small and medium-sized distributed control system to realize decentralized control and centralized management. The upper and lower machines are relatively independent, with manual, automatic and semi-automatic switching functions, and exchange with each other according to specific protocols. When off-line, a single scale can realize closed-loop process control independently. The host computer is far away from the operation site, which improves the stability of the system and improves the working environment of the operators. The lower computer uses programmable control. The device has strong anti-interference ability, simple programming and easy to master, and can run reliably in harsh environment for a long time. PID adjustment is used to improve the dosing accuracy of the system, and can set an excellent work switching sequence according to the production requirements, automatically modify the material ratio of ingredients, and make a perfect production process.
Weighing Feeder includes storage, transportation, weighing and metering, dust removal, material mixing, raw material packaging and filling of powdery, granular, blocky, flaky and liquid materials. According to industry characteristics and process requirements, combined with material characteristics, single batch batching, multi-stage accumulation, weight reduction, weightless scale, belt/screw scale, bulk scale and other measurement methods can be reasonably selected.
