[0036] Working principle: The equipment is installed on the feeding device. During use, the powder is fed into the feed pipe 6 and guided by the guide plate 7 to avoid splashing. When the ion fan 8 is working, it removes static electricity from the passing powder, which then enters the storage tank 2 for storage. During feeding, the heating copper pipe 27 is energized to generate heat. Then, the controller controls the second fan 25 to work, conveying the heat from the annular air outlet pipe 29 and the conveying pipe 28 into the storage tank 2. At the same time, the controller controls the motor 5 to work, driving the stirring rod 10 and the spiral feeding rod 11 to rotate. The rotation of the stirring rod 10 causes the powder to tumble, achieving drying. The temperature is detected by the temperature sensor 18, which receives the signal and transmits it to the controller. When the temperature reaches the target, the controller controls... When the heating copper tube 27 is de-energized, the screw feeder 11 rotates, conveying the powder from the discharge pipe 12 into the weighing tank 13, where it is detected by the weighing sensor 15. Once the detection is qualified, the signal receiver receives and transmits the signal to the controller, which then controls the motor 5 to stop, thus achieving automatic weighing. During feeding, the discharge pipe 12 is placed inside the weighing tank 13, and a first conical baffle 30 and a second conical baffle 31 are placed there to reduce the spread of splashed powder. At the same time, the controller controls the first fan 22 to work, drawing the flying powder into the filter box 21. After being filtered by the filter screen 32, the powder is discharged. The filtered powder is collected inside the filter box 21, reducing spraying or splashing. After weighing is completed, the slide valve 17 is opened, and the vibration motor 35 starts working to feed the powder.
