Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] The screening structure 3 includes a fixed shell 31, a mounting plate 32, a connecting wheel 33, a screening frame 34, a closing cover 35, and a fixing member 36. The bottom of the fixed shell 31 is bolted to the top of the stabilizer 2. The inner side of the fixed shell 31 is bolted to the outer side of the mounting plate 32. The inner wall of the mounting plate 32 is rotatably connected to the outer wall of the connecting wheel 33. The right side of the connecting wheel 33 is fixedly connected to the left side of the screening frame 34. The outer side of the screening frame 34 is movably connected to the inner side of the fixed shell 31.

The bottom of the fixed shell 31 is fixedly connected to and communicates with the top of the fixing member 36.

[0028] In this embodiment: A support platform 1 serves as the basic support structure for the entire sorting device. The support platform 1 bears the entire weight of the stabilizing frame 2, the screening structure 3, and the sorting structure 4. The stabilizing frame 2 provides a stable mounting platform for the screening structure 3. The screening structure 3 includes a fixed shell 31, which provides a mounting base and protective casing for other components, preventing external impurities from entering the screening area and interfering with the sorting process. It also protects internal components from damage and communicates with the fixing member 36 to transport the screened waste powder to the subsequent sorting structure 4. The mounting plate 32 connects... Wheel 33 provides rotational support, enabling the connecting wheel 33 to rotate smoothly, thereby driving the screening frame 34 to move. The screening frame 34 is equipped with multiple layers of screens on its inner side, and feeding can be carried out on its right side to perform fine screening of waste powder. The connecting wheel 33 drives its movement, and the waste powder is screened and separated according to characteristics such as particle size under the action of the screens. The closed cover 35 and the fixed shell 31 form a closed screening area to prevent waste powder from overflowing during the screening process, and at the same time provide support for the rotation of the screening frame 34. The connecting piece 10 is used to transport the screened waste powder to the sorting structure 4.

[0029] Specifically, such as Figure 3 , Figure 5 As shown, the sorting structure 4 includes a connecting shell 41, the top of which is bolted to the bottom of the fixed shell 31.

[0030] Specifically, such as Figure 3 , Figure 5 As shown, the bottom of the connecting shell 41 is fixedly connected to and communicates with the material distribution shell 42, and the inner side of the material distribution shell 42 is bolted with a wire mesh frame 43.

[0031] Specifically, such as Figure 3 , Figure 5 As shown, the outer side of the connecting shell 41 is movably connected to the inner side of the support platform 1, and the outer side of the material distribution shell 42 is movably connected to the inner side of the support platform 1.

[0032] In this embodiment: the sorting structure 4 is provided, wherein the connecting shell 41 serves to connect the screening structure 3 and the material distribution shell 42, so as to smoothly transport the screened waste powder into the material distribution shell 42 for further sorting. The material distribution shell 42 provides space for fine sorting of waste powder. Through the mesh frame 43 provided inside the powder shell 42, the screened waste powder is screened and separated again, further improving the sorting accuracy of waste powder and meeting the requirements of fine sorting.

[0033] Specifically, such as Figure 2 , Figure 4 , Figure 5As shown, a support plate 5 is bolted to the left side of the stabilizer 2, and stabilizing plates 6 are fixedly connected to both sides of the fixed shell 31. The bottom of the stabilizing plate 6 is bolted to the top of the stabilizer 2.

[0034] Specifically, such as Figure 2 As shown, a mating hole 7 is provided on the left side of the mounting plate 32, and the inner wall of the mating hole 7 is rotatably connected to the outer wall of the connecting wheel 33.

[0035] In this embodiment: by setting the support plate 5, the user can install the existing motor equipment on the top of the support plate 5, and connect the motor equipment and the connecting wheel 33 through the belt. The motor equipment can drive the screening frame 34 to rotate. By setting the stabilizing plates 6 fixed on both sides of the fixed shell 31, the fixed shell 31 can be installed on the stabilizing frame 2 through the stabilizing plates 6. Through the mating holes 7 opened in the mounting plate 32, the connecting wheel 33 can rotate on the inner wall of the mounting plate 32, and the mounting plate 32 can support the connecting wheel 33.

[0036] Specifically, such as Figure 2 As shown, a mounting hole 8 is provided on the right side of the closed cover 35, and the inner wall of the mounting hole 8 is rotatably connected to the outer wall of the screening frame 34.

[0037] Specifically, such as Figure 2 As shown, a cleaning hole 9 is provided on the right side of the screening frame 34, and a connector 10 is bolted to the inside of the cleaning hole 9.

[0038] In this embodiment: the mounting hole 8 opened in the sealing cover 35 allows the screening frame 34 to rotate on the inner wall of the sealing cover 35. At the same time, the sealing cover 35 supports the rotation of the screening frame 34. The cleaning hole opened in the screening frame 34 makes it easy for the user to clean the waste powder inside the screening frame 34. The connecting piece 10 is installed inside the screening frame 34 to seal the screening frame 34.

[0039] Working Principle: In applications requiring waste powder processing, the waste powder first enters the screening structure 3 from the right side of the screening frame 34. A motor mounted on the support plate 5 drives the connecting wheel 33 via a belt, which in turn drives the screening frame 34 to rotate within the fixed housing 31. The fixed housing 31 is secured to the stabilizing frame 2 by the stabilizing plate 6, providing a stable space for the screening process. The closed cover 35 prevents powder overflow. As the multi-layered screens within the screening frame 34 rotate, they screen and separate the waste powder according to its particle size and other characteristics, meeting the requirements of different screen apertures. The powder passes through the screen, while larger particles remain on the screen. The waste powder after screening falls into the sorting structure 4 below through the connection between the fixed shell 31 and the fixed part 36. The connecting shell 41 connects the screening structure 3 and the material distribution shell 42, guiding the powder into the material distribution shell 42. The mesh frame 43 inside the material distribution shell 42 screens the screened powder again, further improving the sorting accuracy. The support platform 1 supports the entire device to ensure stable operation. In the whole process, the screening structure 3 performs preliminary screening, and the sorting structure 4 performs deep sorting, realizing the fine sorting of waste powder.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
