In this embodiment, the feeding device further includes a dredging member 33 whose two ends are respectively fixedly connected to the pulling member and the material box 31 . The dredging member 33 includes a dredging rod 331 and a lifting mechanism that drives the dredging rod 331 to move up and down. The driving mechanism can drive the dredging member 33 to reciprocate and slide together with the material box 31 , so that when the dredging member 33 is located above the powder passage 211 , the dredging rod 331 corresponds to the powder passage 211 up and down.

In this embodiment, the limiting member 43 passes through the clamp 44 from bottom to top to fix the measuring cup 41 under the platform 2 . Since in the filling process, the amount of powder that needs to be loaded each time is not the same, in order to make the filling function applicable to a wider range, the measuring cup 41 is preferably a movable sleeve. When the clamp of the measuring cup 41 is in the up and down position, the movable sleeve as the measuring cup 41 also expands and contracts up and down correspondingly, thereby obtaining measuring cups with different capacities. As shown in FIG. 3 , when the bottom of the measuring cup 41 shrinks to position a, the capacity is small; when the bottom of the measuring cup 41 extends to position b, the capacity is large. At the same time, the supporting plate 21 is adjusted to be positioned on a horizontal plane, so that the top openings of all the measuring cups 41 are positioned on the same horizontal plane, thereby ensuring that the capacity of each measuring cup 41 is the same.

In order to make the powder falling into the mold cavity 51 even and smooth, the cross-sectional area of the bottom opening of the measuring cup 41 is set to be 1/2, 1/3, 1/4, 1/4 of the mold cavity 51 cross-sectional area. Or one-fifth, of course other ratios can also be used. Under the condition that the powder flow allows, the smaller the cross-sectional area of the bottom opening of the measuring cup 41 relative to the cross-sectional area of the mold cavity 51, the higher the accuracy of powder filling. This is especially important in the preparation of multilayer materials.

In the primary powder filling process of the embodiment of the present invention, the driving mechanism drives the material box 31 to slide below the hopper 11, the top opening of the material box 31 is aligned with the blanking channel 13, and after the controllable gate 12 is opened, the powder material from The hopper 11 enters the material box 13 through the blanking channel 13 . After the quantitative powder falls into, the controllable gate 12 is closed. The powder first enters the upper material box 312 of the material box 13 , and falls evenly into the lower material box 312 through a plurality of powder leakage pipes 314 provided on the partition 313 . The driving mechanism again drives the material box 31 to slide above the powder passage 211 , and the powder carried in the material box 31 falls into the measuring cup 41 from the powder passage 211 . After the blanking time is over, the driving mechanism operates again, the material box 31 slides back and forth on the supporting plate 21 once, and scrapes the powder on the top opening of the powder channel 211, so that the amount of powder loaded in each measuring cup is the same Yes, and the amount of powder loaded is accurate. After the sliding action of the material box 31 is finished, the controllable valve 42 at the bottom opening of the measuring cup 41 is opened, and the powder falls from the measuring cup 41 into the mold cavity 51 of the mould, thus the primary powder filling process ends. If the powder to be loaded is relatively bonded, it is not easy to fall into it automatically, and the dredging part 33 is started. The driving mechanism first drives the dredging member 33 to move horizontally so that the dredging rod 331 is aligned with the top opening of the measuring cup 41, and then starts the lifting mechanism, driven by the lifting mechanism, the dredging rod 331 moves up and down to assist in pressing out the powder in the measuring cup 41 . Of course, the unclog member 33 is selectively actuatable.

In the second embodiment of the present utility model, the blanking channel 13 of the blanking device is a hose, one end of which is connected to the hopper 11 through the controllable gate 12, and the other end is sealed and connected to the top opening of the material box 31 , thereby conducting with the cartridge 31. The difference from the first embodiment is that when the magazine 31 slides back and forth, the hoses act together. During a powder filling process, when the drive mechanism drives the material box 31 to slide above the powder channel 211 of the pallet 21, that is, when the bottom opening of the material box 31 is aligned with the powder channel 211, the controllable gate of the blanking device 12 is opened, and the powder directly enters the measuring cup 41 through the hose, the feed box 31 and the powder passage 211 in sequence. In this design, the material box 31 is prevented from sliding on the pallet 21 together with the powder, because the uniformity and flatness of the powder in the material box 31 may be damaged during the sliding process.

As can be seen from the above, in the embodiment of the present invention, the material box 31 is designed as a double-layer structure, which increases the process of uniform and smooth powder; at the same time, after the powder is loaded into the measuring cup 41, it passes through the material box 31 reciprocating sliding, scraping off the powder at the top opening of the powder channel 211, while ensuring that the powder is accurately loaded, and ensuring that each measuring cup is filled with the same amount of powder; in addition, the second feeding method is adopted Way, that is, not directly filling and weighing in the mold cavity 51 of the mold, but first weighing the material in the measuring cup 41 outside the mold and then loading it into the mold cavity 51, thus further improving the accuracy of the filler. Using the automatic quantitative powder filling machine according to the embodiment of the utility model, in the production of diamond agglomerates with a multi-layer material structure, the error of each layer of powder loaded is about 0.01g, while other existing powder filling equipment The error is generally as high as 0.05g. If the seven-layer diamond agglomeration is produced, the cumulative error will be even greater.

On the other hand, in the automatic quantitative powder filling machine according to the embodiment of the utility model, an electrically controlled controllable gate 12 is provided in the blanking device, an electronically controlled drive mechanism is provided in the feeding device, and a The measuring cup 41 is provided with a controllable valve 42, so automatic filling can be realized during the filling process, the production efficiency is improved, and the operation is more convenient at the same time.
