[0045] like Figure 1 As shown, during filling, the conveyor belt 63 conveys the bottle 90 to the filling station, the conveyor belt 63 stops, and the first limit rod 66 engages the outer side of the bottle 90. At this time, the bottle 90 is located on the weighing sensor; then, the sleeve 54 is inserted into the inside of the bottle 90, and the exhaust mechanism of the lower bin 30 and the sleeve 54 is opened. Then, as shown in FIG. Figure 4 As shown, the material distribution power element 25 drives the material distribution piece 22 to rotate, so that one end of the material distribution piece 22 abuts against one end of the feed bin 211 close to the second bin 213, thereby closing the second bin 213 and opening the first bin 212; at the same time, the first telescopic power element 27 drives the valve 23 to rotate and open the discharge end of the first bin 212. Feeding begins, and the powder enters the material bottle 90 through the feed bin 211, the first bin 212, the bin body 31 and the discharge pipe 32 in sequence. As the discharge continues, the lifting power element 53 drives the sleeve 54 to gradually rise to prevent the discharge from being affected.

[0046] When the powder reaches a first preset value, the first telescopic power element 27 drives the valve 23 to rotate, so that the valve 23 closes the first unloading part 214, and the powder is unloaded from the second unloading part 215, thereby reducing the unloading amount and the unloading speed and improving the accuracy; when the powder reaches a second preset value, the first telescopic power element 27 drives the valve 23 to continue to rotate, so that the valve 23 closes the first unloading part 214 and the second unloading part 215.

[0047] like Figure 5 As shown, the material distribution power element 25 drives the material distribution piece 22 to flip, so that one end of the material distribution piece 22 abuts against one end of the feed bin 211 close to the first bin 212, thereby closing the first bin 212 and opening the second bin 213. At the same time, the second telescopic power element 44 drives the sealing plate 42 to rotate, thereby opening the vibrating feeder 41, and the powder enters the vibrating feeder 41 through the feed bin 211 and the second bin 213, and then is vibrated and discharged by the vibrating feeder 41, and the powder enters the bin body 31 and the discharge pipe 32; when the final preset value is reached, the second telescopic power element 44 drives the material distribution piece 22 to rotate, so that the sealing plate 42 closes the vibrating feeder 41 to prevent further feeding. Finally, the first limit rod 66 and the second limit rod 68 retreat, and the conveyor belt 63 rotates to convey the finished bottle 90 to the next station, and the cycle repeats.

[0048] The high-precision powder filling device 100 is used for rapid material discharge through the first material bin 212. During rapid material discharge, the valve 23 is used to control the closing of the first material discharge part 214 and the second material discharge part 215, thereby controlling the material discharge amount and the material discharge speed, which not only improves the efficiency, but also can roughly control the accuracy and prevent overfilling; after reaching the preset value, the first material bin 212 is closed, the second material bin 213 is opened, and the material is accurately discharged through the vibrating discharge machine 41, which further improves the material discharge accuracy. Through the segmented discharge, the material discharge accuracy is improved, and the filling efficiency is improved. The air extraction mechanism of the discharge bin 30 is used to timely suck away the flying powder in the discharge bin 30 to prevent the powder from overflowing from the first chute 311 and the second chute 312. The air extraction mechanism of the sleeve 54 is used to timely suck away the flying powder in the bottle 90 to prevent it from overflowing from the bottle 90. Therefore, the high-precision powder filling device 100 is suitable for chemical powders such as toxic rare earths. In addition, there is no metal friction during the entire filling process, and the airtightness is high, which can ensure the purity of the material during filling and is suitable for filling powder with 7N purity.

[0049] The high-precision powder filling device 100 of the present invention controls the feeding of the first material bin 212 or the second material bin 213 through the material dividing piece 22; controls the opening size of the discharge end of the first material bin 212 through the valve 23, thereby controlling the discharge speed; the high-precision powder filling device 100 cooperates with the first material bin 212 through the valve 23 to achieve rapid discharge, and then achieves high-precision discharge through the vibration discharge component 40, which not only improves the discharge speed, but also improves the discharge accuracy, and is easy to use.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
