The Central weighing and unloading system adds the required materials into the mixing bin in turn according to a certain ratio. At the same time, PLC monitors the pulse signal sent by the material level meter to determine the position of the material in the bin, so as to control the on-off of the charging valve; After the feeding is completed, according to the preset mixing delay time, the PLC starts the mixing motor to ensure that the material is fully stirred in the mixing bin to complete the mixing operation; Then enter the discharge and pressing stage, the PLC controls the discharge valve action, the material is output from the mixing bin, pressed into the storage tank, complete a cycle of automatic batching control process.

The Set value batching control system includes screw conveyor, storage bin, gate, cutting device, weighing body, support, electrical control device, etc. The feeding device is fast and slow two-stage feeding mode. The PLC sends a signal to the cylinder to drive the plunging plate to work, and the material in the hopper flows into the weighing bucket, and the weighing module above the weighing bucket sends a signal to the PLC, so as to control the operation of the cylinder. When the weight is approaching the required weight, the PCL sends a signal to the cylinder with plunging plate, so as to slow down the discharge speed. When the value reaches the weighing module, the PLC sends a signal to the cylinder and the plunging plate seals the material port.

Load Batching scales in order to control personnel directly and accurately weighing data of raw materials, the production process can not be a small amount, lack of material, loss of material. To realize the manual or automatic to select the bin number location, the bottom line of the various dosage inventory for automatic alarms and other functions, the digital display of the electronic scales and the PLC and touch screen for information exchange, all system control will be brought together in a special system software, the controller only need to click on the appropriate location to control such as electrical switches, rotating transport components, water, gas valves, etc., the human-machine interface is very good! The human-machine interface is a good way to display the whole production line in the form of dynamic and static diagrams on the computer screen, so that the staff can understand the operation of the whole production of ingredients without leaving home.

The Cleanliness-free dosage scale is made by controlling the related switches, and the human-computer interface is the process of controlling, all the operations are done on the computer software, and any clicks can directly act on the pneumatic valves, prozac uses an electrical control integrating analog and switching quantities, and it completes the corresponding operation according to the requirements of the staff on duty. The PLC output current signal controls the output frequency of the frequency converter, which ultimately regulates the motor speed, thus controlling all the production processes related to the motor.

The Quantitative dosage scale utilizes the analog input template in the PLC to collect the data on site in real time. The actual values are calculated according to the different ranges of the flow rate of each weighing module's measuring tank, and the converted values are averaged to minimize the flow rate fluctuations, which facilitates the application of the weighing values to the PID circuit adjustment and ensures the stability of the weighing adjustment. The display of material level adopts the display mode of one way on site and one way in the main control room, which facilitates the real-time monitoring of the material level of the silo from two aspects, and ensures that when the material level is low, the on-site personnel will take the measure of adding material to prevent the occurrence of material breakage.

The filling machine is equipped with different actuating mechanisms such as barrel feeding, liquid injection, stopper pressing and barrel discharging. To ensure the accuracy of filling, synchronous servo motors are used to directly drive the filling screw, and AC motors are selected to drive the barrel inlet and outlet conveying devices, filling turntables and stopper capping mechanisms. The entire filling system is composed of four units: on-site equipment components, signal acquisition components, command control components and condition monitoring components.

Pneumatic Liquid filling machine is used to send out the request to enter the car number, password, work number, filling and other commands, the weighing system is required to deal with the RF reader, weighing table data, communication of the upper PO and other serial data, the establishment of the barrel ID and information and staff permissions and other databases, so as to facilitate the effective query operation of the lower computer data uploaded when the database receives information indicating the car number and weight, the data is directly recorded in the database When the database receives the information indicating the car number and weight, the data will be recorded into the database directly, and each filling station can output statistics and reports on these data.

Manual Liquid filling machine consists of stepping motor, gear pump filling head, conveyor belt and electrical control box, controlled by PLC programmable, the container is fed into the scale body at the same time when the motorized drum running, weighing module on the photoelectric switch detected by the container issued by the signal, the filling mechanism through the speed reducer to stay in the E stepping motor's output shaft is connected to the drive shaft of the ruler wheel pump, through the control of the stepping motor's running steps to achieve the Accurately control the number of revolutions of the gear pump to achieve the purpose of accurate measurement.

The Explosion-proof automatic filling machine realizes the filling operation diagnosis, real-time monitoring, automatic control and so on to meet the requirements of real-time, stability and reliability of the system. Intelligent multi-functional faceplate, man-machine operation interface is simple and suitable, through the RS-422/485 interface can be rapid communication and setup. The control index of the filling weighing is mainly to judge whether the initial weighing and rechecking weighing related indexes meet the weighing requirements, and the automatic adjustment of the liquid level in the storage tank and the intermediate tank in the filling process, and the control design of the peripheral hand-held code scanner are also an important part of the control part.
