The human-machine interface of the 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.
020-34563445Vacuum weighing system consists of feeding station or material storage bin, vacuum doser weighing device, PLC controller and other components, which can complete the automatic feeding and dosing of single material with fixed weight or multiple materials with different formula dosage. Widely used in medicine, food, chemical, battery materials, building materials, metallurgy, processing and other industries.
Powder vacuum weighing system applied to two materials automatic weighing and dosing as an example to illustrate the working principle of powder vacuum weight-bearing system. Material A, B were stored in two bins, powder vacuum weighing system began to work, the vacuum pump start, material A bin bottom spiral discharge valve A to reach a certain weight, the spiral stops, the discharge valve A closed, the remaining materials in the pipeline continue to be sucked into the weighing hopper, sucked after the net weighing of the material in the scale A weight is exactly the weight of the set. At this time, the screw discharge valve B at the bottom of the material B bin opens, the screw starts, the material B is sucked into the weighing hopper, when the material B in the scale reaches a certain weight, the screw stops, the discharge valve B closes, and the remaining material in the conveying pipe continues to be sucked into the weighing hopper, and after sucking clean, the weight of the material B in the scale is exactly the set weight. The vacuum pump stops.
The vacuum weighing system has the advantages of short process flow, high weighing accuracy, high reliability, highly flexible equipment layout, and greatly reducing the height of the plant than the traditional powder weighing system. According to the different positions of the weighing device in the powder vacuum weighing system, a variety of additive scales and subtractive scales can be composed to meet the different requirements of customers.
