The weighing and feeding system adopts automatic control to realize the automatic control and supervision of raw material loading, weighing and metering, vacuum feeding, mixing and other processes. The dispersion time and cylinder number can be selected and adjusted on the computer according to the production requirements. The opening and closing of the motor equipment and the opening and closing of the feed valve are controlled by the computer. Powder metering and conveying is an automatic control process, using powder metering tank measurement. According to the weight of the feed, the computer control automatically opens the corresponding valve, and the linkage starts the corresponding screw conveyor to start the feed. When the weighing reaches the set value, the interlocking feed valve and screw conveyor of the weighing module close. After the measurement is completed, the discharge valve of the metering tank will automatically open, and the feed valve of the transition tank will be opened, and the powder will enter the transition tank for storage. When the powder is added to the dispersed tank, the bottom of the tank will be loaded, and the vacuum will be pumped in the tank. The discharge valve of the transition tank and the feed valve of the tank will automatically open, and the powder will enter the reaction kettle from the bottom of the tank.

In the production process of the continuous dosing machine, the fillers are continuously and accurately fed into the first pair of screw extruders for premixing through the corresponding metering device, the base material is obtained after degassing and cooling, and then into the second twin screw extruder for further mixing and dispersing, so that the raw materials introduced into the system are transported from the raw material storage tank to the hopper scale through the screw feeding device, and the raw materials in the hopper pass the weighing module. Stop feeding when the weight reaches the upper limit, start feeding when the weight is lower than the lower limit. The weight of the measuring hopper is constantly changing, and it is discharged from the measuring hopper by the discharge pump within the time range. This time is not fed, and the weight of the material in the measuring hopper is a downward trend. Within the time range, because the material in the measuring hopper has reached the lower limit, it needs to be fed, and the weight of the measuring hopper increases.


Application of liquid pumping and mixing batching system
The batching system adopts dual CPU to form a redundant system, and the STEP7MicroWin V4.0SP6 programming software provided by Siemens is used as the man-machine interface to write debugging programs and download programs. The PC and PLC experimental machine are connected by a PC/PPI cable for communication, and the corresponding parameters are set.
Powder Dosing System Design
The automatic dosage system consists of an industrial grade control computer, programmable controllers, and electrical control boxes, and is designed to meet the needs of a maximum number of silos and platform scales for mixing, weighing, and mixing control.
Application of weighing device in automatic glue dosage system
The automatic dosing system can realize the full automatic control of the glue making, glue delivery and glue using process. According to the pre-set ratio and process, the deviation in the dosing process is monitored through the screen, and the dosing ratio behind is corrected according to the ratio of the formula, so as to ensure the accuracy of the formula.
Screw dosage system technology application
Screw automatic dosage system is the ideal equipment for continuous dosage and measurement of bulk materials, which can set high, middle and low feeding, and then control the feeding speed of screw feeder, so as to achieve the purpose of accurate dosage. According to the actual process of batching process, it reflects the operation status of feeding, batching, feeding and related equipment in the form of dynamic screen.
Automatic Powder Batching System
Batching system in the field of powder processing and treatment, the leading technology of powder processing equipment absorbed and optimized in the weighing and mixing machine in accordance with the production instructions and formulas, a variety of materials will be placed, transported to the set station, using automatic walking weighing mechanism, a variety of materials accurately and proportionally added to the barrel.
Reactor feeding and dosage system realization
Reaction kettle feeding dosage system through the explosion-proof electronic weighbridge direct collection of weight signals, automatic control of weighing, the operator through the keyboard or the mouse in the upper computer human-machine interface (HMI) on the input charging information (charging type, weight, etc.), monitoring the whole process of charging control, printing the results of the charging and production reports, to achieve the process of charging the measurement and control of the integration of the management, is not lost as a practicable and effective method.
