The Reaction automatic feeding system (e.g. dosing container with weighing device) reads the weight value at regular intervals, and the difference between the two weights is used to calculate the reduction per time unit (instantaneous flow rate). The weighing controller compares the actual measured value with the preset flow rate value, and at the same time controls the rotational speed of the auger feeder to regulate the feeding volume. When the weight of the material in the hopper reaches the minimum set value, the charging valve will be opened automatically to carry out the periodic charging operation. In order to ensure the correctness of the weighing results, an appropriate filter can be selected to filter the weighing signals during the measurement process.

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.

The Sequence automatic feeding system introduces advanced industrial control computer machine and PLC and DCS system, adopting decentralization, networking and intelligence to ensure the reliability and long-term stability of dosage. Adopting transfer pump to realize liquid dosage with kettle as the control unit, each kettle is set up accordingly to set the recipe boundary for different recipe feeding and conveying, which can flexibly cope with the demand of different recipes for different production batches of tasks.

Powder dosage system can be integrated with existing conveyor weighing systems for warehouse and package picking terminals. TLX Advanced Edition helps you to provide dosage control for revenue, optimize inventory control, save costs and improve operational processes. Meanwhile the configuration control, i.e. data acquisition, uses high-end configuration software as a host computer, through which commands are issued to manage the automation equipment and processes. Through digital and analog inputs and outputs to control various types of batching or production processes, the design should follow the principle of easy integration with industrial control and easy expansion of its functions.

The pellet batching system is controlled by PLC, touch screen and weighing module. The PLC and its corresponding electronic control main circuit are installed in the electrical control cabinet to control the field signal. Touch screen HMI is installed on the surface of the control cabinet to monitor and adjust, display the working status, time setting, ingredient adjustment parameters, alarm information, etc., to improve the reliability of safe operation of ingredients.

Weighing dosing system based on PC and precise quantitative dosing is a set of machine, electricity, signal processing and dosing in one of the technical equipment, electrical part is mainly composed of weighing sensor, weighing instrument, programmable controller (PLC), frequency converter, industrial computer and printer. In the process of dynamic weighing, the weight signal of the weight sensor on the quantitative weighing hopper is received. When the weight of the material in the hopper reaches each set value, the output I/O quantitative signal to the PLC. PLC collects the quantitative output signal of the weighing display instrument, and controls the output frequency of each frequency converter through PLC, so as to control the thickness and fine feeding amount of the corresponding vibration feeder and the switching door action of each weighing hopper.

Powder batching system consists of industrial control computer, control software, system power supply and distribution and on-site inspection and control. Computer constitutes the center of control and management, can operate in general industrial environment, the field of primary signal after conversion, amplification into a standard 4 ~ 20mA signal to OPTO22RTUMUX control machine, the weighing module to send industrial control machine to collect data, scale conversion, filtering and processing with the given value sent to the PID function block operation, respectively, sent two ways to regulate the value of the output of the D / A conversion, all the way! Adjust the frequency converter speed of feeding screw to control the feeding quantity, and adjust the opening degree of electric regulating valve to control the flow of materials, so as to achieve the purpose of feeding materials accurately according to the proportion.

The dust-free automatic feeding system is controlled by PLC timing. The mixer is always stirring. During stirring, liquid is added quantitatively. The material bin must be discharged when the material door of the temporary storage hopper is closed (if the temporary storage hopper is equipped with a weighing scale) and the scale is empty. After the material and miscellaneous bin is closed in place, the temporary storage hopper begins to discharge materials. The external storage tank and the in-plant material silo start to feed materials to the screw after a delay. The amount of material fed is controlled by the opening degree of the material door. The start and stop are controlled according to the start and end of material discharge in the temporary storage hopper. All controls are implemented by the PLC for interlocking control, and the PLC controls the sequential start and stop.

The Measurement feeding system is a complete set of automation equipment that realizes dynamic weighing and batching control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts human-machine configuration, which controls the weight and flow of the materials loaded into the weighing hopper according to the process requirements through the monitoring system and the PLC program, thus realizing the precise measurement and dosage. The weighing system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.
