Description

Technical Field

[0001] This utility model belongs to the field of magnetic powder production and processing technology, and in particular relates to a screening machine for magnetic powder production and processing. Background Technology

[0002] In the prior art, a search revealed a Chinese patent entitled "A Screening Device for Magnetite Powder Production and Processing," with publication number "CN218190844U." This patent mainly involves setting a protective cover between the first filter section and the connecting section. When the magnetite powder in the device is screened, due to the mechanical rotation, some of the powder floats in the air and then falls back onto the screening plate after being blocked by the protective cover. This ensures that the powder is fully utilized and prevents the powder from spreading into the working area, thus protecting the hygiene of the working area.

[0003] Magnetic powder can be classified into several grades based on particle size, such as coarse powder, medium powder, fine powder, micro-fine powder, and ultra-fine powder. Different grades of magnetic powder have different functions in different application scenarios. However, when the above-mentioned device screens raw materials, it can only screen the material once. When screening powders of different particle sizes, it is necessary to frequently change the screen. Changing the screen takes a certain amount of time, which increases the time used in the entire screening process and results in low screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a screening machine for the production and processing of magnetic powder. By setting up a screening mechanism, materials of different diameters can be separated and collected, which can greatly improve the collection efficiency. This solves the problem that the above-mentioned devices perform single screening of materials and require frequent screen replacement when screening different granular powders in the raw materials, resulting in low screening efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a screening machine for the production and processing of magnetic powder, including a base plate, on which a screening mechanism and an anti-blocking mechanism are provided;

[0007] The screening mechanism includes a support frame fixedly connected to the top surface of the base plate. Four springs are fixedly connected to the top surface of the support frame. A hopper is fixedly connected to the top of each of the four springs. Two fixed rods are fixedly connected to the top surface of the hopper. Three fixed frames are fixedly connected to the outer walls of the two fixed rods. Screens are fixedly connected to the inner walls of each of the three fixed frames. The three screens are inclined and arranged inside the screens. A discharge frame is connected to the outer walls of each of the three fixed frames and is fixedly connected to the fixed frames. Baffles are slidably connected to the inner walls of each of the three discharge frames. A discharge pipe is connected to the bottom surface of each of the three discharge frames and is fixedly connected to the discharge pipe. A discharge port is opened on the outer walls of each of the three fixed frames. The three baffles are slidably connected to the outer walls of the three fixed frames respectively. A vibration motor is fixedly connected to the top surface of the hopper.

[0008] Furthermore, the anti-blocking mechanism includes a valve ball slidably connected to the inner wall of the hopper, and a rotating rod fixedly connected to the outer wall of the valve ball, with one end of the rotating rod away from the valve ball extending rotatably to the outside of the hopper.

[0009] Furthermore, the inner wall of the hopper is provided with four grooves, and the inner walls of the four grooves are slidably connected with universal joints. The hopper is provided with a connecting block, and the outer wall of the connecting block is provided with four grooves. The inner walls of the four grooves are slidably connected with universal joints. The four universal joints and the four universal joints are respectively fixedly connected with telescopic rods.

[0010] Furthermore, the outer walls of all four telescopic rods are wound with springs II, one end of which is fixedly connected to the telescopic rod, and the other end of which is fixedly connected to universal joint II.

[0011] Furthermore, four hinge blocks are fixedly connected to the bottom of the connecting block, and hinge rods are rotatably connected to the inner walls of the four hinge blocks.

[0012] Furthermore, each of the four hinge rods has a sliding plate rotatably connected to one end away from the hinge block, and the side of each of the three sliding plates away from the hinge rods is slidably connected to the inner wall of the hopper.

[0013] Furthermore, a collection box is fixedly connected to the top surface of the base plate, the collection box is located below the hopper, an inclined plate is fixedly connected to the inner wall of the collection box, and a door is hinged to the front side of the collection box.

[0014] This utility model has the following beneficial effects:

[0015] 1. By incorporating a screening mechanism, the spring and the hopper work together to drive the vibrating motor, causing the hopper and multiple fixed frames on it to vibrate. Magnetic powder raw materials can then be poured into the uppermost fixed frame, allowing the vibrating screens to screen the material. The three screens have different mesh sizes, gradually decreasing in diameter from top to bottom, enabling the screens to grade and screen the raw materials. The screens are also inclined, allowing the material to slide down to the discharge port after vibration screening. Multiple baffles can then be opened, allowing materials of different diameters to be discharged separately from the three discharge pipes. This separates and collects materials of different diameters, eliminating the need for frequent screen replacements and significantly improving collection efficiency.

[0016] 2. Equipped with an anti-blocking mechanism, after the material is screened, it falls to the bottom of the hopper. At this point, the rotating rod can be turned to open the valve ball, discharging the screened material. Simultaneously, the vibration motor can be turned on, causing the connecting block to slide back and forth slightly inside the hopper. With the cooperation of multiple hinge rods and sliding plates, multiple sliding plates will also produce slight wobbling, causing the material at the bottom of the hopper to shake, preventing material from accumulating inside the hopper and causing blockage, thus improving the material's flowability. At the same time, groove one, universal joint one, connecting block, groove two, universal joint two, and telescopic rod work together to support the shaking of the connecting block, while spring two works in conjunction with the telescopic rod to enhance the shaking frequency of the connecting block, further improving the material's flowability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Baffles 28 are slidably connected to the inner walls of each of the three discharge frames 27. Discharge pipes 29 are connected to the bottom surfaces of each of the three discharge frames 27 and are fixedly connected to the discharge pipes 29. Discharge ports 291 are opened on the outer walls of each of the three fixing frames 25. The three baffles 28 are slidably connected to the outer walls of the three fixing frames 25 respectively. A vibrating motor 4 is fixedly connected to the top surface of the hopper 23. A screening mechanism 2 is provided, and a spring 22 cooperates with the hopper 23 so that when the vibrating motor 4 is driven, the hopper 23 and multiple fixed frames 25 on the hopper 23 can vibrate. At this time, the magnetic powder raw material can be poured into the uppermost fixed frame 25, so that the vibrating screen 26 can vibrate and screen the raw material. The filter holes of the three screens 26 are different in size, and the diameter of the filter holes gradually decreases from top to bottom, so that the screens 26 can classify and screen the raw material. The screens 26 are set at an inclination so that the raw material can slide to the discharge port 291 after vibration screening. At this time, multiple baffles 28 can be opened so that materials of different diameters can be discharged from the three discharge pipes 29 respectively, so that materials of different diameters can be collected separately without frequent replacement of filter screens, thereby greatly improving the collection efficiency.

[0029] The anti-blocking mechanism 3 includes a valve ball 31 slidably connected to the inner wall of the hopper 23. A rotating rod 32 is fixedly connected to the outer wall of the valve ball 31. One end of the rotating rod 32 away from the valve ball 31 extends rotatably to the outside of the hopper 23. The inner wall of the hopper 23 has four grooves 33. The inner walls of the four grooves 33 are slidably connected to universal joints 34. A connecting block 35 is provided inside the hopper 23. The outer wall of the connecting block 35 has four grooves 36. The inner walls of the four grooves 36 are slidably connected to universal joints 37. The four universal joints 34 and the four universal joints 37 are connected to each other. Each of the four sections 37 is fixedly connected to a telescopic rod 38. A spring 39 is wound around the outer wall of each of the four telescopic rods 38. One end of the spring 39 is fixedly connected to the telescopic rod 38, and the other end is fixedly connected to the universal joint 37. Four hinge blocks 391 are fixedly connected to the bottom of the connecting block 35. A hinge rod 392 is rotatably connected to the inner wall of each of the four hinge blocks 391. A sliding plate 393 is rotatably connected to the end of each of the four hinge rods 392 away from the hinge block 391. The side of each of the three sliding plates 393 away from the hinge rod 392 is connected to the hopper 23. The inner wall of the hopper 23 is slidably connected, and a collection box 5 is fixedly connected to the top surface of the bottom plate 1. The collection box 5 is located below the discharge hopper 23. An inclined plate 394 is fixedly connected to the inner wall of the collection box 5, and a door 395 is hinged to the front side of the collection box 5. After the material is screened by an anti-blocking mechanism 3, the material will fall to the bottom of the discharge hopper 23. At this time, the rotating rod 32 can be rotated to open the valve ball 31 and discharge the screened material. At the same time as the material is discharged, the vibration motor 4 can be turned on, so that the connecting block 35 slides back and forth slightly inside the discharge hopper 23. With the cooperation of the hinge rod 392 and the sliding plate 393, multiple sliding plates 393 will also produce a small amplitude of shaking, which will cause the material at the bottom of the hopper 23 to shake, preventing the material from accumulating inside the hopper 23 and causing blockage, and improving the flowability of the material. At the same time, the groove 1 33, universal joint 1 34, connecting block 35, groove 2 36, universal joint 2 37 and telescopic rod 38 cooperate with each other to support the shaking of the connecting block 35. The spring 2 39 cooperates with the telescopic rod 38 to enhance the shaking frequency of the connecting block 35, further improving the flowability of the material.

[0030] A specific application of this embodiment is as follows: By setting up a screening mechanism 2, the spring 22 and the feeding hopper 23 cooperate with each other, so that when driving the vibration motor 4, the feeding hopper 23 and the multiple fixed frames 25 on the feeding hopper 23 can be driven to vibrate. At this time, the magnetic powder raw material can be poured into the uppermost fixed frame 25, so that the vibrating screen 26 can vibrate and screen the raw material. The filter holes of the three screens 26 are different in size. From top to bottom, the diameter of the filter holes gradually decreases, so that the screens 26 can classify and screen the raw material. The screens 26 are set at an inclination, so that the raw material can slide down to the discharge port 291 after vibration screening. At this time, multiple baffles 28 can be opened, so that materials of different diameters can be discharged from the three discharge pipes 29 respectively, so that materials of different diameters can be collected separately without frequent replacement of the filter screen, thereby greatly improving the collection efficiency.

[0031] With the anti-blocking mechanism 3 in place, after the material is screened, it falls to the bottom of the hopper 23. At this time, the rotating rod 32 can be rotated to open the valve ball 31 and discharge the screened material. At the same time as the material is discharged, the vibration motor 4 can be turned on, causing the connecting block 35 to slide back and forth slightly inside the hopper 23. With the cooperation of multiple hinge rods 392 and sliding plates 393, the multiple sliding plates 393 will also shake slightly, causing the material at the bottom of the hopper 23 to shake, preventing the material from accumulating inside the hopper 23 and causing blockage, thus improving the flowability of the material. At the same time, the groove 1 33, universal joint 1 34, connecting block 35, groove 2 36, universal joint 2 37 and telescopic rod 38 cooperate with each other to support the shaking of the connecting block 35. The spring 2 39 cooperates with the telescopic rod 38 to enhance the shaking frequency of the connecting block 35, further improving the flowability of the material.
