GF8 Automatic batching system

The automatic batching system can complete the automatic feeding of A single material with fixed weight or the automatic feeding of different ingredients of A variety of materials. It is suitable for the automatic weighing of two kinds of materials, powder powder vacuum weighing system, material A and B are stored in two silos respectively. The powder weighing system starts to work, the vacuum pump starts, and the screw discharge valve A at the bottom of the powder silo of material A reaches a certain weight. The discharge valve A is closed, and the material remaining in the conveying pipe continues to be sucked into the weighing hopper, and the weight of material A in the scale is exactly the set weight after being sucked.

The Batching system adopts the intermittent static weighing principle, and each cycle completes the process of feeding, weighing, discharging, mixing and re-feeding. The effects of feeding impact, uneven tare weight and zero drift are overcome to a certain extent. According to different processes, the setting of parameters is different, but it is mainly the setting of the relationship between the output and the ratio of the stage. When the parameters are set, start the system. During the batching operation, the dynamic detection of each batching scale is carried out to preliminarily judge whether the feeding material reaches the set value of the batching. If the set value is dynamically detected, the feed is stopped. After the shutdown buffer a certain amount of time to start weighing. For the feeding error caused by dynamic detection and the single dosing error caused by other reasons, this error can be reduced by the next dosing supplement or a certain algorithm.

The whole system can be divided into four parts, namely the detection part, the data processing part, the man-machine interface part and the control part. The detection part is mainly to amplify the very low signal from the weighing module through the preamplifier, and then take out the interference through the filter circuit, and then convert the analog signal into digital signal through the analog-to-digital converter to the MCU. The human-machine interface part mainly deals with the interaction with people, one is to display the status of the system operation to the user through the display device such as the monitor, the other is to input the parameters of the system operation to the computer through the input device such as the keyboard. The control part mainly controls the execution device through the driver, in which the motor is used to control the opening and closing action during the discharge, and the electric vibration machine controls the action of the discharging. The data processing part is the core of the ingredients, which is mainly responsible for coordinating the work of the other three parts, and completing the data processing task, such as converting the signal transmitted by the weighing module into the corresponding weight information and displaying it through the human-machine interface part, and controlling the start and stop of the motor and electric vibration machine according to the current state of feeding or discharging.


Operation management of belt scale in dosage system
The belt scale receives the speed signal of SR and the weight signal, calculates the instantaneous flow rate of the material on the belt and displays it, compares the actual value of the flow rate with the set value of the flow rate, and through PID regulation, the output current control signal is amplified by the preamplifier and the power amplifier Q to control the conduction angle of the SCR VT and thus regulate the rotational speed of the sliding motor M, so as to make the material flow rate stabilize at the expected set value.
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.
