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 automated feeding system is controlled by PLC timing, the mixer is always stirring, the liquid is added quantitatively when mixing, the silo must be released when the hopper door is closed (if the hopper is equipped with a weighing scale) and the scale is empty. The hopper will start to release material after the bin is closed in place. External storage tanks and internal silos start to feed material to the screw after a delay, the amount of material to be fed is controlled by the opening of the material door, and the starting and stopping is controlled according to the start and end of the discharge of material from the hopper. All controls are interlocked by PLC, which controls the start and stop.

The 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.

The automatic batching equipment controls the temperature in the reaction tank within a certain range during the whole system operation, and controls the temperature sensor in the jacket temperature design. The communication between the industrial control computer and the site reactor can be adjusted according to the time required for the complete reaction of the material. The reaction tank temperature and jacket temperature cascade proportioning composed of computer and electric regulating valve, the selection of control mode and control algorithm, the setting of set values and related parameters, and the display box of the real-time curve of the reaction tank temperature control, make the proportion coefficient and online debugging, the integration time and differential time can be adjusted intuitively and timely according to the shape of the real-time curve of the temperature in the reaction tank. Get full scale.

The feeding mechanism of the batching equipment is connected with the reactor, and the method of feeding two-speed feeding is adopted. When the weighing feeder stops feeding, part of the material falls into the weighing hopper in free fall in the air. The set value of the weight of the incremental method should be the standard weight value of the material to be formulated minus the drop value. By automatic weighing the bulk material according to the predetermined ratio, the weighing amount of the material can be controlled and the material can be discharged at the same time. When the material is completed, the pointer is moved to the corresponding proximity switch to make the action, and then the next step of material feeding and weighing is carried out, and so on until all the material ratio is complete.

The feeding system is mainly used in plastic injection, extrusion or hollow process where a variety of raw materials are mixed according to weight ratio. The setting data will not be lost after the power is cut off by EEPROM, no battery is used; Use the human-machine interface status display touch keyboard data input, more convenient operation, but also can store a large number of formula data (500 groups); High speed and high precision AD grab weight faster and more stable; All the boredom is evenly mixed after gravity measurement, which can strictly control the accuracy. Check the weight data and the selected raw materials to ensure the precision and accuracy of the mix.
