[0041] The use method and working principle of the device are as follows: First, when the integrated precision batching and unloading operation of the powder is carried out, the powder is sucked in through the powder feeding pipe 9 by the powder pump 8, wherein the photoelectric sensor 10 monitors the powder conveying state in real time, and then the sucked powder in the powder feeding pipe 9 is accurately measured by the feed metering feeder 29 and put into the drying and pressurizing box 140, and according to the operation, the nitrogen pressurizing tank 123 adjusts the nitrogen pressure through the nitrogen control regulator 124, and the nitrogen enters the drying and pressurizing box 140 through the pressurizing pipe 125, providing a dry and pressure environment for the powder, realizing the continuous, quantitative, and precise conveying and processing of the powder, improving the production efficiency and product quality, and then using the angle control base 110 to The motion controller 111 is connected to the angle control base 110 through a line. The motion controller 111 accurately controls the rotation angle of the angle control base 110 according to the preset program instructions or real-time feedback signals to ensure that the motion trajectory and posture of the entire structure meet the operation requirements. Then, the electric angle rotation section 112 is driven by the angle control base 110 to rotate the hydraulic cylinder 113 and the rotating support nuclear scale 114 together. The hydraulic cylinder 113 drives the rotating support nuclear scale 114 to perform lifting and rotation adjustment, so as to complete the support rotation of the drying and pressurizing box 140. When the powder is transported later, the controlled rotation of the drying and pressurizing box 140 is used to stably support the drying and pressurizing box 140. 40 and the powder loaded inside, avoiding the accumulation or spillage of powder due to angle change, and when the drying and pressurizing box 140 is adjusted to a suitable angle, the powder inside can be smoothly transferred from the drying and pressurizing box 140 to the drying spiral rake feeding structure 142 due to gravity, so as to realize the directional and quantitative transportation of the powder, and at the same time, the rotating support nuclear scale 114 can accurately weigh the powder in real time during the rotation process, so as to ensure the accuracy and consistency of the powder processing, improve the flexibility and accuracy of the powder transportation, reduce the material loss, and improve the efficiency and safety of the whole production process. When the drying and pressurizing box 140 is rotated and adjusted to the inside of the microwave temperature control adjustment end 6, the powder is The temperature is controlled in the temperature control regulating end 6, and the control motor 141 is started to drive the drying spiral rake feeding structure 142 to operate through the bottom output end, so that the powder is evenly and continuously conveyed and dried. The rotating support nuclear scale 114 is connected to the side wall of the drying pressurizing box 140 through the hoop sleeve 13, so that the powder can be weighed in real time and accurately during the powder conveying process. Due to the high-precision characteristics of the nuclear scale in the rotating support nuclear scale 114, the weight data of the powder can be accurately obtained even when the powder is constantly flowing, thereby realizing accurate control of the powder conveying amount. At the same time, the synchronous wheel 121 is operated when the equipment is started as a whole, driving the nitrogen pressurizing tank 123 to enter the working state, and according to the process requirements, the pressure and flow of nitrogen are set by the nitrogen control regulator 124, and the nitrogen is conveyed from the nitrogen pressurizing tank 123 to the feed metering feeder 29 and the drying pressurizing box 140 through the pressurizing pipe 125.At the same time, the pressure sensor 33 is used to monitor the pressure change in the pipeline in real time. When the pressure exceeds the preset range, the control system automatically adjusts the nitrogen control regulator 124 according to the feedback information of the pressure sensor 33, so that the nitrogen pressurized tank 123 can stably output gas to maintain a constant nitrogen pressure, and through the support steering member 27, it is ensured that the pressurized pipe 125 can be flexibly turned synchronously during the rotation and adjustment operation of the drying pressurized box 140 to ensure the continuity and stability of nitrogen delivery. Secondly, the dried and pressurized powder is passed through the soft conveying pipe into the pneumatic quantitative feeder 16 for accurate measurement, and the measured powder is monitored and controlled in real time by the weight loss scale 17 to ensure that the delivery volume meets the set value, and then the weight loss scale 17 conveys the powder to the increasing The weighing scale 30 performs secondary confirmation and cumulative measurement, so that the weight-increasing scale 30 distributes the powder to two groups of powder storage tanks 198 through the feeding powder pipe 32, so that the powder storage tank 198 receives and stores the powder according to the instruction of the feed control valve, which is convenient for the subsequent formation of a main and a standby powder operation structure or a synchronous operation structure, so that the entire structure can ensure the accurate proportioning and processing of the powder in each link through multiple metering and control equipment, thereby improving the stability of the overall process and product quality. Then, the driving motor drives the feeding spiral structure 199 to rotate in the powder storage tank 198 through the gear set and the toothed belt, and the powder in the powder storage tank 198 is fed into the screw powder feeder 191, and the weighing module 192 monitors in real time. The weight of the powder in the screw powder feeder 191 is measured, and the data is transmitted to the PID controller 193, so that the PID controller 193 adjusts the screw rotation controller 196 according to the set parameters and real-time weight information, thereby controlling the speed and feeding amount of the screw feeding. When the powder in the discharge container 194 reaches the set amount, the ultrasonic sensor 195 sends a signal, and the electric powder valve opens, so that the powder enters the preliminary wetting box 180 from the discharge container 194 through the pneumatic powder discharge air duct to receive preliminary wetting treatment. Then the atomization adjustment pump 182 draws water from the water tank 183, atomizes it through the pipeline, and sprays it into the preliminary wetting box 180 and the high-efficiency wetting box 181, so that the powder continues to flow into the high-efficiency wetting box 181 after preliminary wetting. 81, it undergoes a more detailed wetting treatment again, and after the powder enters the mixing and unloading box 220 through the pipeline, the wetting adjustment atomizing nozzle 28 adjusts the size and spray volume of the atomized water droplets according to the preset parameters to meet the wetting requirements of different powders. Then the water volume in the water tank 183 is monitored and replenished in real time to the mixing and unloading box 220 through the water inlet valve pipe to ensure the continuity and stability of the entire wetting process. The system continuously optimizes and adjusts the feeding speed through closed-loop control to ensure the accuracy and stability of feeding and discharging. When the powder enters the mixing and unloading box 220, the stirring control motor 221 is started to drive the conical spiral ribbon agitator structure 222 to stir the powder in the mixing and unloading box 220.The conical spiral ribbon agitator structure 222 can effectively utilize the gravitational potential energy of the powder, so that the powder forms an up and down circulation flow under the spiral propulsion. At the same time, the conical structure is conducive to the automatic gathering of the powder to the center, ensuring that the powder can be fully mixed in the entire stirring and unloading box 220. Then, the angle of the stirring and unloading box 220 is adjusted by using the angle rotation structure 21 to improve the uniformity of powder mixing and the convenience of subsequent unloading operations. Then, the air compression transmitter 23 is used to flush the powder adhered to the inner wall surface of the powder storage tank 198 and the drying and pressurizing box 140 according to the preset program. After the impact, the whole amount of powder can be sent into the mixing and unloading box 220 according to the accuracy of weighing, and according to the needs, the angle and position of the mixing and unloading box 220 can be adjusted by operating the supporting rotating hydraulic cylinder structure 26 through the hydraulic system to cooperate with the rotation adjustment operation of the above-mentioned angle rotating structure 21. After that, when the overall mixing is completed, the discharge valve 25 is opened, and the powder is discharged to the designated position evenly and orderly through the discharge pipe 24, and the equipment can be moved to the next operation area under the traction of the mobile bearing base frame 1, and the above process is repeated to realize continuous and efficient powder processing and transportation operations.
