[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-6 As shown, the sieving device for powder processing includes: a vibrator 1, a screen 10, and a guide plate 11.

[0033] The vibrator 1 is fixedly connected to a housing 2 at its top. The housing 2 has several feed holes 9 along its width at its top. A screen 10 is disposed inside the housing 2, with both sides of the screen 10 fixedly connected to the inner wall of the housing 2. A discharge hopper 7 is fixedly connected to the side of the screen 10, with both sides of the discharge hopper 7 fixedly connected to the housing 2. A guide plate 11 is disposed at the bottom of the screen 10, with both sides of the guide plate 11 fixedly connected to the housing 2. Several discharge ports 12 are opened along the width at the bottom of the guide plate 11. The operator pours powder into the housing 2 through the feed holes 9. At this time, the vibrator 1 operates. Okay, the vibrator 1 drives the outer shell 2 to vibrate vertically. The outer shell 2 carries the screen 10 and the guide plate 11 to vibrate. When the powder falls onto the screen 10, the vibrating screen 10 screens the powder. The screened powder falls onto the guide plate 11, and the remaining particles are on the screen 10. At this time, the screened powder and the remaining particles begin to flow downward. The powder is discharged from the outlet 12, and the particles are discharged from the discharge hopper 7. This achieves the effect of automatically removing the remaining particles and avoids the particles remaining on the screen 10 from affecting the screening effect of the powder.

[0034] The powder can enter the outer shell 2 through the feed hole 9. The multiple outer shells 2 make it easy for workers to pour multiple portions of powder into the outer shells 2. At the same time, it ensures that the powder can be evenly spread on the outer shells 2, which further improves the efficiency of powder screening. The outer shells 2 achieve the effect of sealing the powder, preventing the powder from splashing during screening.

[0035] In some specific implementations, a plurality of feed hoppers 3 are fixedly connected to the top of the outer shell 2 along the width direction. The feed hoppers 3 are interconnected with the feed holes 9. When the powder is poured into the outer shell 2, the powder can be poured into the feed hoppers 3. The feed hoppers 3 transport the powder, and the powder passes through the feed holes 9 and is poured onto the screen 10. The feed hoppers 3 achieve the function of guiding the powder and prevent the powder from falling onto the surface of the outer shell 2.

[0036] In some specific implementations, the screen 10 and the guide plate 11 are both inclined in the direction of the discharge hopper 7. The top of the screen 10 is provided with a sealing plate 4, which is set on the outer shell 2. The inclined arrangement of the screen 10 and the guide plate 11 can further improve the efficiency of the flow of powder and residual particles. When the powder screening is finished, some particles will be blocked on the screen 10.

[0037] In some specific embodiments, the sealing plate 4 is fixedly connected to a supporting plate 5 on its side. The top of the outer shell 2 has a cleaning port 14, and the two sides of the outer shell 2 have sliding grooves 13 respectively. The sealing plate 4 is used to seal the cleaning port 14. The inner wall of the sliding groove 13 is slidably connected to the sealing plate 4 and abuts against the feed hopper 3. The two sides of the supporting plate 5 have threaded holes 15 penetrating the interior of the outer shell 2. The inner wall of the threaded holes 15 is threaded with a screw 6. The screw 6 is connected to the supporting plate. 5. With the support plate 5 in place, the operator can control the support plate 5 to pull the sealing plate 4. The sealing plate 4 slides along the slide groove 13 on both sides, thereby releasing the blocking effect on the cleaning port 14. The operator can then clean the particles blocking the screen 10, making it easier for the screen 10 to screen the powder again. When the sealing plate 4 blocks the cleaning port 14, the screw 6 is threaded into the threaded hole 15 to fix the support plate 5, and then the sealing plate 4 is fixed to the outer shell 2.

[0038] In some specific implementations, the discharge hopper 7 is in communication with the interior of the outer shell 2. When it can be discharged from the outer shell 2, the particles are discharged along the discharge hopper 7, and the discharge hopper 7 plays a guiding role for the particles.

[0039] In some specific implementations, a plurality of discharge pipes 8 are fixedly connected to the bottom end of the guide plate 11 along the width direction. The discharge pipes 8 are interconnected with the discharge port 12. The discharge pipes 8 are cylindrical in shape, and a fixing groove 18 is provided on the outer wall of the discharge pipe 8. A fixing strap 16 is abutted and connected to the inner wall of the fixing groove 18. A locking member 17 is fixedly connected to the side end of the fixing strap 16. Before the powder is discharged from the discharge port 12, the collection bag is put on the discharge pipe 8, and then the fixing strap 16 is put on the collection bag. The fixing strap 16 is held in the fixing groove 18, and the locking member 17 is fixed on the fixing strap 16, thereby fixing the collection bag on the discharge pipe 8. When the powder is discharged from the discharge port 12, the powder can flow along the discharge pipe 8 into the collection bag, thereby avoiding the phenomenon of powder splashing when entering the collection bag.

[0040] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
