The feeding system automatically transports all kinds of materials to the batching tank through the material conveying device, and then automatically weighs them in proportion and accurately, and then automatically transports the well-proportioned mixed materials to the reaction kettle for mixing, and then automatically discharges the materials after mixing. The material feeding mechanism is connected with the reactor, and the material in the reactor can be transported out evenly. Material handling and inclined handling can be performed according to job requirements. In the production process or process flow, the requirements for various ingredients weighing, quantitative weighing and on-site technology are becoming higher and higher. Weighing test is a very important link in the ratio.

Weighing dosing machine will mix four kinds of powder materials, when the start button, send electrical signals to the material conveying mechanism, at this time the motor of the weighing feeding mechanism is energized and begins to rotate, the motor drives the Feeder to transport the material to the hopper Electronic scale, supported by three Weighing modules, when the weight of a material reaches 95%, the system sends electrical signals to the motor to reduce the motor speed. Make it slow feed to reduce the impact of the symmetrical hopper and reduce the error. When a material reaches the set value, the motor of the feeding mechanism stops the operation of the feeding mechanism, and sends an electrical signal to the feeding mechanism of the second material to start weighing the second material. By analogy, the load-bearing capacity of the four materials is completed. When the weighing is completed, the solenoid valve is controlled, and the electrical signal is sent to the reaction tank door at this time, so that the cylinder pushes the door, and the door is opened to complete the unloading. When the discharge is finished, then control the solenoid valve type cylinder to pull the valve to close. Finally, the motor of the control stirring mechanism is energized and begins to stir, and the electric signal is sent after the stirring is uniform. The stirring motor stops working and automatically opens the discharge door. When the discharge is completed, the next cycle begins.

The Weighing system uses the weight signal converted by the strain gauge pressure sensor to control the asynchronous motor and control the spiral. When the spiral is mixed with various raw materials and sent to an empty bin, the weighing system begins to work. The induction motor starts, drives the coarse screw propeller to rotate, and pushes the fertilizer to fall from the blanking tube through the mixer in proportion. When the falling powder is close to the set weight (slightly less than the set weight), stop the coarse screw propeller feed material. The control stepper motor screw thruster is then started to make micro additions until the fertilizer weight meets the requirements of the given weight. After the weight in the silo meets the requirements, the powder is passed to the next process by the screw for feeding, and the empty silo in the back is transmitted for weighing, and the mixer feeds the outlet, so it works again and again. Powder weighing is divided into two stages, the first stage by asynchronous motor driven coarse screw propeller feed, this stage can be seen as a coarse adjustment process, feed weight must be less than the rated weight. The second stage is the stepper motor driven by the fine screw propeller feed, see as a fine adjustment process to make the actual weight equal to the required rated weight.
