The lower end of the arc-shaped connecting plate 1703 is hollow and has a first through hole 17011. The upper end of the arc-shaped connecting plate 1703 is connected to the second cylinder 1701. 01. The first baffle 1705 is fixedly installed with screws at the lower end, either by screws or by welding. The first baffle 1705 and the arc-shaped connecting plate 1703 form a first receiving cavity 17010. A plurality of the fifth sliders 1704 are installed in the first sliding groove 1709 in the arc-shaped connecting plate 1703. The second telescopic rod 1702 of the second cylinder 1701 is connected to the plurality of the fifth sliders 1704. The extension and retraction of the second telescopic rod 1702 can drive the plurality of fifth sliders 1704 in the first... The fifth motor 1706 slides up and down within the slide groove 1709; the fifth motor 1706 and the motor base 1708 are fixedly installed together with screws, and the motor base 1708 is also fixedly installed with the second bracket 7 with screws; a first lead screw 17013 is also provided inside the motor base 1708, one end of the first lead screw 17013 is connected to the output shaft of the fifth motor 1706 through a coupling, and the other end is rotatably connected to a bearing on the motor base 1708; the first lead screw 17013 is also connected to the sixth slider 170... 7. The connection is made by internal and external threads; the sixth slider 1707 is also provided with first protrusions 17014 on both sides, and the motor base 1708 is provided with second sliding grooves 17015 on both sides inside, which cooperate with the first protrusions 17014; the sixth slider 1707 is also fixedly installed with the second cylinder 1701 by screws; under the action of the fifth motor 1706 and the first lead screw 17013, the sixth slider 1707, the second cylinder 1701 and the arc-shaped connecting plate 1703 can be driven to move up and down.

[0033] Through the first through hole 17011, the powder in the weighing pan 6 can flow into the first receiving cavity 17010; the fifth slider 1704 can slide up and down to control the opening size of the first through hole 17011, thereby controlling the amount of powder flowing in; when a certain amount of powder flows into the first receiving cavity 17010, the fifth slider 1704 slides down to seal the first through hole 17011.

[0034] like Figure 18 As shown, it is worth mentioning that several fifth sliders 1704 are hinged together, wherein the upper end of the first fifth slider 1704 is fixed to the second telescopic rod 1702.

[0035] Furthermore, the motor mount 1708 is detachable, making it convenient to install the sixth slider 1707.

[0036] The working principle of the robotic arm 17 is as follows: When the robotic arm 17 needs to remove excess powder, the moving device 9 moves the robotic arm 17 above the weighing pan 6, and the fifth motor 1706 is activated, causing the sixth slider 1707, the second cylinder 1701, and the arc-shaped connecting plate 1703 to move downwards. At this time, the first through hole 17011 is open, and the lower end of the arc-shaped connecting plate 1703 extends into the weighing pan 6. The powder in the weighing pan 6 flows into the first receiving cavity 17010 through the first through hole 17011. Then, the second cylinder 1701... The telescopic rod 1702 moves downward, causing several fifth sliders 1704 to slide downward and block the first through hole 17011. Then, the fifth motor 1706 is activated, driving the sixth slider 1707 to move upward, thereby moving the arc-shaped connecting plate 1703 upward away from the weighing pan 6. The moving device 9 is then activated, moving the robotic arm 17 above the receiving cylinder 19. Afterward, the second telescopic rod 1702 of the second cylinder 1701 retracts upward, exposing the first through hole 17011 and allowing the powder to fall into the receiving cylinder 19. It is worth noting that the up-and-down movement of the fifth sliders 1704 controls the opening size of the first through hole 17011, thus controlling the powder inflow. The opening size of the first through hole 17011 can be preset via the system.

[0037] In order to facilitate the quick insertion of the arc-shaped connecting plate 1703 into the weighing pan 6 for material retrieval, a first base plate 17012 is respectively (welded) on both sides of the bottom surface of the lower end of the arc-shaped connecting plate 1703, and the cross section of the first base plate 17012 is V-shaped.

[0038] Furthermore, the weighing pan 6 includes a tray 601 and a weighing body 602. The tray 601 is placed above the weighing body 602, and the weighing body 602 is fixedly mounted on the first bracket 2. The weighing body 602 includes a housing, and a positioning mechanism and a weighing sensor are disposed inside the housing.

[0039] The intelligent precision weighing method for powder includes the following process: S1, the weighing pan 6 is set to a specific weight; S2, the powder is poured into the first feed port 8 and the second feed port 10, entering the second housing 3. The stirring device 4 and the conveying device 5 start working. The stirring device 4 stirs the powder, and the conveying device 5 feeds the stirred powder. The speed of the screw propeller 502 of the conveying device 5 is controlled to control the amount of powder conveyed. Finally, the powder is conveyed to the weighing pan 6 for weighing; S3, according to the program setting, when the weight of the weighing pan 6 is insufficient, a second slow feeding is performed. After the slow feeding is accurate, the stirring device 4 and the conveying device 5 stop working, and the sealing device 16 seals the outlet 11, ending the feeding process; S4, according to the program setting, when the weight of the weighing pan 6 is excessive, the robotic arm 17 removes the excess powder. If the robotic arm 17 removes too much powder, slow feeding is performed again until the set weight is reached.

[0040] All the aforementioned electronic components are controlled by a controller, and the weighing weight is also controlled by input from the controller. The symmetrical weighing disc 6 is then gripped, and a robotic arm is also included; however, this is not described in detail here.
