[0035] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0036] See Figure 1 and Figure 2 This utility model provides a powder metallurgy proportioning and metering device, including a conveyor belt 1 and multiple powder silos 5. Multiple metering devices 2 are arranged above the conveyor belt 1. Each metering device 2 has a screw feeder 3 connected to its inlet end and a rotary feeder 4 connected to its outlet end, with the outlet end of the rotary feeder 4 facing the conveyor belt 1. The other end of each screw feeder 3 is connected to the outlet end of the corresponding powder silo 5, allowing the material in the powder silo 5 to be conveyed to the metering device 2. Each powder silo 5 has a filter cartridge dust collector 6 at its inlet end. The conveyor belt 1 can be an existing conveyor belt; the screw feeder 3 can be an existing screw feeder; and the filter cartridge dust collector 6 can be an existing dust collector that filters dust.

[0037] With the above structure, through the cooperation of multiple metering devices 2, multiple screw feeding devices 3, multiple rotary feeding devices 4 and multiple powder bins 5, the screw feeding device 3 can transport the powder in the corresponding powder bin 5 to the metering device 2 for weighing. When the weight ratio is reached, the screw feeding device 3 can be stopped. Then, the rotary feeding device 4 discharges the powder in the metering device 2 onto the conveyor belt 1, and the conveyor belt 1 transports the powder to the next process. This avoids manual weighing and proportioning, thus saving manpower.

[0038] In one embodiment, see Figure 1 and Figure 3The metering device 2 includes a frame 21, on which a metering barrel 22 is mounted. The feeding end of the metering device 2 is a feed pipe 221 at the top of the metering barrel 22, and the discharging end of the metering device 2 is a discharge pipe 222 at the bottom of the metering barrel 22. The feed pipe 221 is connected to the discharge end of the screw feeder 3, and the discharge pipe 222 is connected to the feeding end of the rotary feeding device 4. A connecting frame 23 is mounted on the metering barrel 22, and the connecting frame 23 is connected to the frame 21 via a metering sensor 24. The metering sensor 24 may also be equipped with a calibration system. This calibration system can be an existing system capable of calibrating the weight of various containers, mainly used to ensure measurement accuracy. The specific calibration principle will not be elaborated further. The metering sensor 24 can be an existing weighing sensor. In practical applications, with the cooperation of the metering barrel 22 and the metering sensor 24, the powder fed into the metering barrel 22 by the screw feeder 3 can be sensed by the metering sensor 24.

[0039] A vibration motor 25 is installed in the metering barrel 22 near the discharge pipe 222. In practical applications, the vibration motor 25 can prevent the powder in the metering barrel 22 from clumping, and at the same time, it can prevent powder residue from remaining on the inner wall of the metering barrel 22 during the feeding process, so as to ensure the accuracy of the proportioning.

[0040] The top of the metering hopper 22 is provided with an exhaust port 223, and a dust collector 26 is connected to the exhaust port 223. In practical applications, the combination of the exhaust port 223 and the dust collector 26 ensures that when the screw feeder 3 conveys powder into the metering hopper 22, the gas discharged from the metering hopper 22 can be discharged through the exhaust port 223. With the dust collector 26 installed, it can prevent the powder from generating flying dust when entering the metering hopper 22, which is then discharged through the exhaust port 223. This ensures that the air pressure inside and outside the metering hopper 22 is balanced, allowing the screw feeder 3 to smoothly feed powder into the metering hopper 22.

[0041] In one embodiment, see Figure 4 , Figure 5 and Figure 6The rotary feeding device 4 includes a feeding cylinder 41 connected to the discharge end of the metering device 2. The feeding cylinder 41 is provided with a feeding chamber 411. The top of the feeding chamber 411 is provided with a feeding inlet 412 that communicates with the discharge end of the metering device 2, and the bottom is provided with a feeding outlet 413, so that the feeding outlet 413 faces the conveyor belt 1. The feeding inlet 412 and the feeding outlet 413 are both connected to the feeding chamber 411. A feeding impeller 42 is rotatably connected in the feeding chamber 411. The feeding impeller 42 is driven to rotate by a feeding motor 43. Multiple feeding blades 421 are provided on the feeding impeller 42. In practical applications, the feeding impeller 42 in the feeding cylinder 41, in cooperation with the feeding motor 43, can drive the feeding impeller 42 to rotate, causing multiple feeding blades 421 to rotate along the axis of the feeding impeller 42. This allows the powder on the feeding inlet 412 to be carried through the feeding chamber 411 to the feeding outlet 413, thereby realizing the feeding action and conveying the powder in the metering barrel 22 to the conveyor belt 1.

[0042] Along the rotation direction of the feeding impeller 42, cleaning components 45 are provided at the ends of multiple feeding blades 421. Each cleaning component 45 includes a fixing part 451 mounted on the feeding blades 421, and a flexible scraper 452 is provided on the fixing part 451. The end of the flexible scraper 452 tightly abuts against the inner wall of the feeding chamber 411. The flexible scraper 452 can be made of rubber. In practical applications, the cleaning component 45 and the fixing part 451 can fix the flexible scraper 452 to the feeding blades 421, and the flexible scraper 452 can effectively scrape away powder from the inner wall of the feeding chamber 411, ensuring the accuracy of the powder ratio.

[0043] The feeding impeller 42 is connected to the feeding motor 43 via a transmission mechanism 44. A transmission shaft 422 is mounted on the feeding impeller 42. The transmission mechanism 44 includes a driving gear 441 mounted on the output end of the feeding motor 43 and a driven gear 442 mounted on the transmission shaft 422. The driving gear 441 and the driven gear 442 are connected by a transmission chain 443. In practical applications, the transmission mechanism 44, through the cooperation of the driving gear 441, driven gear 442, transmission chain 443, and transmission shaft 422, transmits power from the feeding motor 43 to the feeding impeller 42, causing the feeding impeller 42 to rotate and thus achieving the feeding action.

[0044] In one embodiment, see Figure 1 The feed pipe 221 of the metering barrel 22 is connected to the discharge end of the screw feeder 3 via a flexible connector 7. In practical applications, the flexible connector 7 ensures the stability of the connection between the feed pipe 221 of the metering barrel 22 and the discharge end of the screw feeder 3.

[0045] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
