Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a magnetic powder core screening device. Background Technology

[0002] In the production of magnetic core powder, sieving is a crucial step in ensuring product quality. Magnetic core powder typically has a wide particle size distribution, requiring sieving equipment to separate it into different particle size specifications to meet the needs of various applications.

[0003] Materials tend to concentrate in one spot on the screen, leading to material accumulation. This accumulation not only reduces screening efficiency but also affects screening accuracy due to excessive local pressure, resulting in uneven particle size distribution after screening and affecting product quality. In addition, material accumulation may also cause screen blockage, increasing equipment maintenance costs and downtime, and reducing production efficiency.

[0004] Therefore, a magnetic powder core powder screening device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a magnetic powder core sieving device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A magnetic core powder screening device includes a frame, on which a screening mechanism is provided for screening magnetic core powder. A material lifting mechanism is provided on one side of the frame, and a corrugated discharge pipe is connected to the discharge end of the material lifting mechanism. A reciprocating mechanism is provided on the top of the frame and on the screening mechanism, and the end of the corrugated discharge pipe is fixedly inserted into the moving part of the reciprocating mechanism.

[0007] Furthermore, the screening mechanism includes a vertical rod movably inserted into the top of the frame, a screening box fixedly installed at the top of the vertical rod, a spring sleeved on the surface of the vertical rod, and the two ends of the spring fixedly connected to the frame and the screening box respectively. A partition is fixedly installed on the inner wall of the screening box, and the interior of the screening box is divided into multiple discharge chambers. Multiple discharge ports are provided on the surface of the screening box, and the discharge ports are symmetrically arranged with the discharge chambers. Screening metal mesh is fixedly installed on the inner wall of the screening box and the top surface of the partition. A vibrating motor is fixedly installed on the bottom surface of the screening box, and baffles are fixedly installed on the inner walls of both sides of the screening box.

[0008] Furthermore, the surface of the screening metal mesh is provided with meshes of different diameters, with the mesh diameters increasing sequentially and corresponding to the discharge chambers respectively.

[0009] Furthermore, the baffles located on the inner walls of both sides of the screening box have an eight-shaped structure, which are closely attached to the top surface of the screening metal mesh and located above the discharge chamber.

[0010] Furthermore, the material lifting mechanism includes a lifting pipe fixedly installed on one side wall of the frame by a bracket. A hopper is provided on the surface of the lifting pipe. A first motor is fixedly installed on the top surface of the lifting pipe. The output end of the first motor passes through the lifting pipe and is fixedly connected to a spiral auger. A corrugated discharge pipe is fixedly connected to the output end of the lifting pipe.

[0011] Furthermore, the reciprocating mechanism includes two sets of parallel side frames fixedly installed on the top surface of the frame. A second motor is fixedly installed on the surface of one of the side frames, and a reciprocating threaded rod is fixedly connected to the output end of the second motor. Guide rods are fixedly installed on the opposite surfaces of the two side frames. A movable frame is threadedly fitted on the surface of the reciprocating threaded rod, and the end of the corrugated discharge pipe is fixedly inserted into the movable frame.

[0012] The beneficial effects of this utility model are as follows: The material lifting mechanism is located on one side of the frame.

Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 4 As shown, a magnetic core powder sieving device includes a frame 1, on which a sieving mechanism 2 is provided for sieving magnetic core powder. like Figure 1 , Figure 3 and Figure 4As shown, specifically, the screening mechanism 2 includes a vertical rod 201 movably inserted into the top of the frame 1. A screening box 203 is fixedly installed at the top of the vertical rod 201. A spring 202 is sleeved on the surface of the vertical rod 201. The two ends of the spring 202 are fixedly connected to the frame 1 and the screening box 203, respectively. A partition 204 is fixedly installed on the inner wall of the screening box 203. The interior of the screening box 203 is divided into multiple sets of discharge chambers 205. Multiple sets of discharge ports 207 are provided on the surface of the screening box 203. The discharge ports 207 are symmetrically arranged with the discharge chambers 205. A screening metal mesh 206 is fixedly installed on the inner wall of the screening box 203 and the top surface of the partition 204. A vibration motor 208 is fixedly installed on the bottom surface of the screening box 203. Baffle plates 209 are fixedly installed on the inner walls of both sides of the screening box 203.

[0019] More specifically, each discharge chamber 205 has a corresponding sieve metal mesh 206 fixed at its bottom. After the powder is sieved by the sieve metal mesh 206 in the sieve box 203, powders of different particle sizes will fall into the corresponding discharge chamber 205 and be discharged through the discharge port 207 on its surface. The vibration motor 208 is fixed to the bottom surface of the sieve box 203 as its vibration source.

[0020] In some practical applications, the surface of the screening metal mesh 206 is provided with meshes of different diameters, with the mesh diameters increasing sequentially and corresponding to the discharge chambers 205 respectively.

[0021] More specifically, the screening metal mesh 206 increases in mesh diameter from top to bottom. When powder enters the screening box 203 from the top, it first comes into contact with the finest mesh. Powder with a particle size larger than this mesh is trapped on the surface of the screening metal mesh 206, while even finer powder falls into the next layer. In the next layer, finer powder with a particle size larger than that layer's mesh is also trapped, and so on. The discharge chamber 205 below each layer of mesh collects powder with a uniform particle size between the upper and lower mesh sizes, thus achieving precise multi-stage screening.

[0022] In some practical applications, the baffles 209 located on the inner walls of both sides of the screening box 203 are in a V-shape, which are closely attached to the top surface of the screening metal mesh 206 and located above the discharge chamber 205.

[0023] More specifically, the baffles 209 located on the inner walls of both sides of the screening box 203 form a guide channel, the main function of which is to guide the powder falling from above to the central area of ​​the screening metal mesh 206, so as to make full use of the screen surface.

[0024] A material lifting mechanism 3 is provided on one side of the frame 1, and a corrugated discharge pipe 4 is connected to the discharge end of the material lifting mechanism 3; like Figures 1 to 3As shown, specifically, the material lifting mechanism 3 includes a lifting pipe 301 fixedly installed on one side wall of the frame 1 by a bracket. A hopper 302 is provided on the surface of the lifting pipe 301. A first motor 303 is fixedly installed on the top surface of the lifting pipe 301. A spiral auger 304 is fixedly connected through the lifting pipe 301 at the output end of the first motor 303. A corrugated discharge pipe 4 is fixedly connected to the output end of the lifting pipe 301.

[0025] More specifically, the output shaft of the first motor 303 extends downward into the pipe, driving the auger 304 to rotate. The rotating auger 304 pushes the powder in the hopper 302 upward from the bottom of the lifting pipe 301 along the pipe until it is discharged from the top outlet and enters the corrugated discharge pipe 4, completing the lifting and conveying process.

[0026] A reciprocating mechanism 5 is provided on the top of the frame 1 and on the screening mechanism 2, and the end of its corrugated discharge pipe 4 is fixedly inserted into the moving part of the reciprocating mechanism 5. like Figures 1 to 3 As shown, specifically, the reciprocating mechanism 5 includes two sets of parallel side frames 501 fixedly installed on the top surface of the frame 1. A second motor 502 is fixedly installed on the surface of one of the side frames 501. A reciprocating threaded rod 503 is fixedly connected to the output end of the second motor 502. Guide rods 504 are fixedly installed on the opposite surfaces of the two side frames 501. A movable frame 505 is threadedly fitted on the surface of the reciprocating threaded rod 503. The end of the corrugated discharge pipe 4 is fixedly inserted into the movable frame 505.

[0027] More specifically, the second motor 502 drives the reciprocating threaded rod 503 to rotate, and the moving frame 505 achieves linear reciprocating motion under the guidance of the threaded pair and the guide rod 504. The end of the corrugated discharge pipe 4 is fixedly inserted into the moving frame 505, so the end of its corrugated discharge pipe 4 also moves back and forth, evenly sprinkling the powder on the width direction of the screening metal mesh 206.

[0028] In summary: The material lifting mechanism 3 is set on one side of the frame 1, and the powder to be screened is lifted from a low position to the feed point of the screening mechanism 2 through the corrugated discharge pipe 4. At the same time, the end of the corrugated discharge pipe 4 is driven to reciprocate through the reciprocating mechanism 5, so that the powder conveyed by the material lifting mechanism 3 is evenly and repeatedly spread on the entire screen surface of the screening mechanism 2, avoiding local accumulation of powder and greatly improving screening efficiency and screen utilization.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
