The human-machine interface of the Spiral feeding system is developed based on the operating system, which can meet the requirements of monitoring and controlling the production process as well as archiving and processing the production data. The user interface drawn by WinCC is simple and easy to operate with a good human-machine interface, which can dynamically display the operation status of various equipment on the site and the various parameters of the dosage operation. The operator can also flexibly control the starting and stopping of the field equipment and change the operating parameters of the dosage according to the needs.
020-34563445The screw feeding system has the advantages of short process flow, high weighing accuracy, high reliability, highly flexible equipment layout and significant reduction in factory building height compared with the traditional powder Weighing system. According to the different positions of the weighing equipment in the powder vacuum Batching system, various additive scales and subtractive scales can be formed to meet the different requirements of customers.
The vacuum weighing system is composed of a feeding station or material storage bin, a vacuum Feeder weighing device, a PLC controller and other components. It can complete the automatic feeding and batching of a single material with a fixed weight or multiple materials with different formulas. It is widely applied in industries such as medicine, food, chemical engineering, battery materials, building materials, metallurgy, and feed processing.
Take the application of the powder vacuum weighing system in the automatic weighing and batching of two materials as an example to illustrate the working principle of the powder vacuum load-bearing system. Materials A and B are respectively stored in two silos. The powder vacuum weighing system starts to work, and the vacuum pump is activated. When the screw discharge valve A at the bottom of the powder silo of material A reaches A certain weight, the screw stops and the discharge valve A closes. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After being sucked clean, the weight of material A in the scale is exactly the set weight. At this point, the screw discharge valve B at the bottom of the material B silo opens, the screw starts, and material B is sucked into the weighing hopper. When the weight of material B in the scale reaches a certain level, the screw stops and the discharge valve B closes. The remaining material in the conveying pipe continues to be sucked into the weighing hopper. After being sucked clean, the weight of material B in the scale is exactly the set weight. The vacuum pump stops.
The vacuum weighing system has advantages over the traditional powder weighing system, such as a shorter process flow, higher weighing accuracy, higher reliability, highly flexible equipment layout, and a significant reduction in factory building height. According to the different positions of the weighing device in the powder vacuum weighing system, various additive scales and subtractive scales can be formed to meet the different requirements of customers.
