Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to an automatic feeding device for a metal powder vibrating screening device. Background Technology

[0002] Metal powder refers to a group of metal particles with a size of less than 1 mm. It includes single metal powders, alloy powders, and powders of certain refractory compounds with metallic properties. It is the main raw material for powder metallurgy. Metal powders need to be screened before being put into use to ensure that they are not mixed with a large number of other impurities.

[0003] Currently, vibrating screens are commonly used in the screening of metal powders. However, most vibrating screens have a vertical feeding structure, meaning they feed from top to bottom. This feeding method makes it difficult to control the feeding speed and amount, leading to excessively fast material falling and excessive feeding. As a result, the material accumulates on the screen, easily causing blockages and affecting screening efficiency. Furthermore, it puts excessive pressure on the vibrating screen, which can easily damage the device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding device for a metal powder vibrating sieve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeding device for a vibrating screen of metal powder includes a screen body. A support frame is fixedly connected to the left side of the screen body, and a stabilizing plate is fixedly connected to the top of the support frame. A feeding assembly is fixedly connected to the upper surface of the stabilizing plate. A feed pipe is connected to the upper surface of the feeding assembly. A feed hopper is fixedly connected to the top of the feed pipe. An end cap is threadedly connected to the top of the feed hopper. The feeding assembly includes a feeding frame. A servo motor is fixedly connected to the front of the feeding frame. A circular shaft is fixedly connected to the output end of the servo motor. A sleeve is fixedly connected to the surface of the circular shaft. Five baffles are fixedly connected to the surface of the sleeve. A strip-shaped feeding frame is fixedly connected to the right side of the feeding frame. A strip-shaped hole is opened on the right side of the feeding frame at a position corresponding to the strip-shaped feeding frame.

[0007] Preferably, the upper surface of the feeding frame is provided with a circular hole that matches the feeding pipe, and the rear end of the circular shaft extends into the interior of the feeding frame and is rotatably connected to the inner rear wall of the feeding frame.

[0008] Preferably, the front and rear lengths of the baffle plate are the same as the front and rear inner wall lengths of the feeding frame, and the end of the strip feeding frame away from the feeding frame is connected to the upper surface of the screening device body.

[0009] Preferably, an arc-shaped frame is fixedly connected to the inner bottom wall of the feeding frame. A sliding groove is provided on the upper surface of the arc-shaped frame. A leak-proof plate is slidably connected to the inner wall of the sliding groove. A right-angle frame is fixedly connected to the lower surface of the leak-proof plate. A limit groove is provided on the left inner wall of the sliding groove. A locking rod is fixedly connected to the inner bottom wall of the limit groove. A spring is sleeved on the surface of the locking rod. The right-angle frame is slidably connected to the inner wall of the limit groove and to the surface of the locking rod. The top end of the spring overlaps with the lower surface of the right-angle frame, and the bottom end of the spring overlaps with the inner bottom wall of the limit groove. The position of the leak-proof plate corresponds to the position of the baffle plate.

[0010] Preferably, a sealing frame is fixedly connected to the upper surface of the feeding frame, a strip frame is fixedly connected to the upper surface of the sealing frame, a hydraulic cylinder is fixedly connected to the inner front wall of the strip frame, a connecting frame is fixedly connected to the output end of the hydraulic cylinder, the end of the connecting frame away from the hydraulic cylinder extends into the interior of the sealing frame and is fixedly connected to an arc-shaped clamping plate, and an arc-shaped hole is opened on the surface of the feeding pipe.

[0011] Preferably, the upper surface of the sealing frame is provided with a through hole that is compatible with the connecting frame, the arc-shaped card plate is slidably connected to the upper surface of the feeding frame, and the arc-shaped card plate is compatible with the arc-shaped hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] By configuring the feeding assembly, a servo motor drives a circular shaft to rotate at a constant speed during operation, which in turn drives several baffles to rotate counterclockwise. This allows the raw material between every two baffles to enter the strip feeding frame in batches and then into the interior of the screening device, achieving continuous intermittent feeding operation. This ensures that too much raw material does not accumulate on the screen during the screening process, guaranteeing effective screening and improving screening efficiency. The hydraulic cylinder, connecting frame, and arc-shaped clamping plate reduce the feeding speed and amount of raw material in the feed pipe, ensuring that the space between the two baffles is not quickly filled, effectively preventing the servo motor from being blocked by raw material. Furthermore, the anti-leakage plate ensures that raw material will not fall through the gap between the baffle and the inner wall of the right side of the feeding frame. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example:

[0021] Reference Figure 1-4 An automatic feeding device for a metal powder vibrating sieve includes a sieve body 1, a support frame 2 fixedly connected to the left side of the sieve body 1, a stabilizing plate 3 fixedly connected to the top of the support frame 2, a feeding assembly fixedly connected to the upper surface of the stabilizing plate 3, a feed pipe 4 communicating with the upper surface of the feeding assembly, a feed hopper 5 fixedly connected to the top of the feed pipe 4, an end cap 6 threadedly connected to the top of the feed hopper 5, a feeding frame 7, a servo motor 8 fixedly connected to the front of the feeding frame 7, a circular shaft 9 fixedly connected to the output end of the servo motor 8, a sleeve 10 fixedly connected to the surface of the circular shaft 9, five baffle plates 11 fixedly connected to the surface of the sleeve 10, a strip-shaped feeding frame 12 fixedly connected to the right side of the feeding frame 7, and a strip-shaped hole opened on the right side of the feeding frame 7 corresponding to the position of the strip-shaped feeding frame 12.

[0022] The upper surface of the feeding frame 7 has a circular hole adapted to the feed pipe 4. The rear end of the circular shaft 9 extends into the interior of the feeding frame 7 and is rotatably connected to the inner rear wall of the feeding frame 7. The front and rear lengths of the baffle plate 11 are the same as the front and rear inner wall lengths of the feeding frame 7. The end of the strip-shaped feeding frame 12 away from the feeding frame 7 is connected to the upper surface of the screening device body 1. After opening the end cover 6, the raw material is poured into the feed hopper 5. At this time, the raw material enters the feeding frame 7 through the feed pipe 4 and falls into the space between the two baffle plates 11. The servo motor 8 can drive the sleeve 10 to rotate at a constant speed through the circular shaft 9. The sleeve 10 can drive several baffles 11 to rotate counterclockwise, thereby driving the raw material between two baffles 11 to rotate to the position of the strip hole, so that the raw material can automatically slide into the strip feeding frame 12 and fall into the screening device body 1, completing continuous intermittent feeding. This ensures that the amount of raw material entering the screening device body 1 each time is not too much, reducing the pressure on the screening device body 1, while ensuring the screening effect of the raw material.

[0023] An arc-shaped frame 13 is fixedly connected to the inner bottom wall of the feeding frame 7. A groove is formed on the upper surface of the arc-shaped frame 13. A leak-proof plate 14 is slidably connected to the inner wall of the groove. A right-angle frame 15 is fixedly connected to the lower surface of the leak-proof plate 14. A limit groove is formed on the left inner wall of the groove. A locking rod 16 is fixedly connected to the inner bottom wall of the limit groove. A spring 17 is sleeved on the surface of the locking rod 16. The right-angle frame 15 is slidably connected to the inner wall of the limit groove and to the surface of the locking rod 16. The top end of the spring 17 overlaps with the lower surface of the right-angle frame 15, and the bottom end of the spring 17 overlaps with the inner bottom wall of the limit groove. The position of the leak-proof plate 14 is... The baffle plate 11 is positioned accordingly. After the baffle plate 11 moves to the position of the right strip hole during rotation, it can contact the leak-proof plate 14 and drive the leak-proof plate 14 to move downward. The leak-proof plate 14 can drive the spring 17 to deform through the right angle frame 15, so that the upper part of the leak-proof plate 14 is always in contact with the lower part of the baffle plate 11, ensuring that the raw material will not fall from the gap to the bottom position of the feeding frame 7 after the baffle plate 11 tilts. Until all the raw material on the baffle plate 11 slides down to the strip feeding frame 12, the baffle plate 11 is separated from the leak-proof plate 14. At this time, the spring 17 generates a reaction force to drive the leak-proof plate 14 back to its original position.

[0024] A sealing frame 18 is fixedly connected to the upper surface of the feeding frame 7. A strip frame 19 is fixedly connected to the upper surface of the sealing frame 18. A hydraulic cylinder 20 is fixedly connected to the inner front wall of the strip frame 19. A connecting frame 21 is fixedly connected to the output end of the hydraulic cylinder 20. The end of the connecting frame 21 away from the hydraulic cylinder 20 extends into the interior of the sealing frame 18 and is fixedly connected to an arc-shaped clamping plate 22. An arc-shaped hole is opened on the surface of the feed pipe 4. A through hole adapted to the connecting frame 21 is opened on the upper surface of the sealing frame 18. The arc-shaped clamping plate 22 and the feeding frame 7 are connected. The upper surface is slidably connected, and the arc-shaped clamping plate 22 is adapted to the arc-shaped hole. When the hydraulic cylinder 20 rotates and changes in the space of the baffle plate 11, it can drive the arc-shaped clamping plate 22 to insert into the arc-shaped hole through the connecting frame 21 and compress the space inside the feed pipe 4, thereby reducing the falling speed and amount of raw materials. This ensures that the raw materials will not quickly fill the space between the two baffle plates 11, but will be added slowly, which greatly reduces the situation where the servo motor 8 is blocked, and also ensures that the amount of material fed each time will not be too much, reducing the pressure on the screening device body 1.

[0025] Working principle: First, open the end cover 6 and pour the raw material into the feed hopper 5. At this time, the raw material enters the feeding frame 7 through the feed pipe 4 and falls between the two baffle plates 11 on the surface of the sleeve 10. The servo motor 8 drives the sleeve 10 to rotate at a constant speed through the circular shaft 9. When the position between the two baffle plates 11 rotates to the right, the space between the other two baffle plates 11 rotates to the top. The raw material in the space that rotates to the right position can enter the strip feeding frame 12 through the strip hole and automatically slide down into the body 1 of the screening device by gravity. The baffle plates 11 can squeeze the anti-leakage plate 14, so that the anti-leakage plate 14 drives the spring 17 to descend through the right angle frame 15. The deformation ensures that the raw material will not fall through the gap between the baffle plate 11 and the right inner wall of the feeding frame 7. When the baffle plate 11 is disengaged from the anti-leakage plate 14, the raw material slides completely into the strip feeding frame 12. The spring 17 generates a reaction force to drive the anti-leakage plate 14 back to its original position. The hydraulic cylinder 20 can drive the arc-shaped clamping plate 22 to be inserted into the feed pipe 4 through the connecting frame 21. This ensures that the raw material does not fall too fast during the rotation of the baffle plate 11, which would cause the gap between the two baffle plates 11 to be filled. This enables continuous intermittent feeding and reduces the pressure on the screening device body 1. Therefore, the raw material can be effectively screened each time, improving the screening effect.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
