Description

Technical Field

[0001] This invention relates to the field of magnetic powder production technology, specifically to a conveying device for magnetic powder production. Background Technology

[0002] Magnetic powder is the core component of magnetic coatings and a major factor determining the magnetic properties of magnetic recording media. During production and processing, magnetic powder requires a corresponding conveying device to transport it to different equipment for processing. Currently, most methods use conveyor belts for conveying magnetic powder. For example, a leak-free magnetic powder conveying device (publication number CN218988219U) includes a support frame, a conveying cylinder installed inside the support frame, an inlet pipe connected to the top left of the conveying cylinder, an outlet pipe connected to the bottom right of the conveying cylinder, a conveying component installed inside the conveying cylinder, a drying component rotatably connected to the top of the conveying cylinder, and a cleaning component movably connected to the bottom left of the drying component. By incorporating the drying component, the magnetic powder during conveying is dried. Compared to traditional structures, this device, by rotating a cover plate at the top of the conveying cylinder and using a drying heating pipe, can dry the magnetic powder conveyed in the conveying cylinder, solving the problem that existing conveying equipment for magnetic powder processing cannot dry the magnetic powder, and preventing small amounts of moisture adhering to the surface of the magnetic powder from affecting subsequent processing. For example, a conveying device for magnetic powder processing, with announcement number CN210392990U, includes a housing. Support legs are fixedly connected to the four corners of the bottom of the housing. A motor is fixedly connected to the left side of the bottom of the housing, and a shell is fixedly connected to the left side of the housing. The output end of the motor extends through the inner cavity of the shell and is fixedly connected to a drive wheel. A rotating rod is provided in the inner cavity of the shell, and a driven wheel is fixedly connected to the left side of the rotating rod. By using the housing, shell, motor, support legs, reinforcing rod, discharge pipe, cover, feed hopper, driven wheel, belt, drive wheel, round pipe, spiral blades, connecting pipe, rotating rod, heat insulation plate, heater, opening, and isolation net in combination, the problem that existing conveying devices for magnetic powder processing cannot dry magnetic powder is solved. This conveying device for magnetic powder processing has the advantage of being able to dry magnetic powder and is worth promoting. However, the above-mentioned magnetic powder conveying device still has the following disadvantages in actual use: 1. Before processing, magnetic powder contains not only fine floating powder but also other impurities. Therefore, it needs to be removed before being conveyed to the processing equipment. However, most traditional conveying equipment does not have a structure for removing impurities from magnetic powder and requires an additional structure for removing impurities. As a result, dust and other impurities may fall into the magnetic powder during the conveying process. 2. Furthermore, when the magnetic powder falls onto the conveying equipment, there is a large accumulation of magnetic powder. Its distribution on the conveying equipment is not uniform enough, which easily causes the magnetic powder to stick together and clump together. There is a lack of structure to disperse the magnetic powder.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing conveying equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying device for magnetic powder production, so as to solve the problem that most traditional conveying devices mentioned in the background art do not have a structure for removing impurities from magnetic powder and lack a structure for dispersing magnetic powder.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for magnetic powder production, comprising a conveyor belt, side guard plates provided on both sides of the conveyor belt, the inner side of the conveyor belt being in contact with the surface of the magnetic plate, and a top plate fixed between the two side guard plates, with the magnetic plate located directly below the top plate. It also includes a cleaning mechanism, which is installed on the top plate. The cleaning mechanism removes impurities by moving the magnetic powder and generating suction force. The cleaning mechanism and the magnetic plate work together to remove impurities.

[0006] Preferably, the length and width of the magnetic plate are both smaller than the length and width of the top plate, and a motor is installed on the upper end surface of the top plate. A connecting plate is fixed on the output shaft of the motor, and guide wheels are rotatably provided at both ends of the connecting plate. When the connecting plate rotates, it can drive the guide wheels to contact the side of the movable box.

[0007] Preferably, the surface of the guide wheel is in close contact with the side of the movable box, and the two movable boxes are connected to each other by a spring. The movable boxes slide against the inner wall of the support plate, while the support plate is fixed to the lower end face of the top plate, and the two movable boxes move in opposite directions.

[0008] Preferably, the lower end face of the movable box is glued to one end of the connecting hose, and the other end of the connecting hose is fixed with a lever. The lever is hollow, and there is a gap between the bottom of the lever and the conveyor belt. The connecting hose and the lever are evenly distributed on the movable box. The lever is connected to the movable box through the connecting hose, so that the lever can improve the dispersion effect of the magnetic powder by shaking when it moves.

[0009] Preferably, the bottom of the lever has a heat exhaust hole, and the lever is connected to the inside of the strip box through a connecting hose. The strip box is fixed to the inner bottom surface of the movable box, and adjacent movable boxes are connected to each other through a fixed pipe. The heat generated by the heating plate can be transferred to the magnetic powder through the heat exhaust hole to ensure its dryness.

[0010] Preferably, the strip boxes are evenly distributed within the movable box, and a heating plate is provided in the movable box in the middle position. Furthermore, the height of the strip boxes is lower than the height of the internal cavity of the movable box. Therefore, the arrangement of the strip boxes facilitates heat transfer and does not affect the removal of impurities.

[0011] Preferably, the impurity removal mechanism includes a suction fan at the edge of the top plate, and the output end of the suction fan is connected to the interior of the movable box through an air supply hose, and the air supply hose slides through the top plate, and the suction force generated by the suction fan is transmitted to the movable box through the air supply hose.

[0012] Preferably, the interior of the movable box is connected to the interior of the fixed box through a through groove and a fixing hole, and the two ends of the fixed box are fixed to the side guard plate. The length of the fixed box is equal to the maximum distance between the two movable boxes, and the movable box can slide against the support plate and the fixed box when it moves.

[0013] Preferably, the through groove is opened on the lower end face of the movable box and the through groove is arranged between two adjacent strip boxes. The fixing hole is arranged on the top of the fixed box, and the bottom of the fixed box is reserved with feed holes at equal intervals. The side of the fixed box is fixed with fixing blocks at equal intervals, and the fixing blocks and the lever are in close contact.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This magnetic powder production conveying equipment can disperse accumulated magnetic powder while it is being conveyed on a conveyor belt. On the one hand, it ensures dispersion and prevents agglomeration by breaking up any clumps of magnetic powder. On the other hand, the generated heat dries the magnetic powder. Simultaneously, it removes floating powder and other impurities from the magnetic powder, achieving the purpose of impurity removal. The specific details are as follows: 1. When the connecting plate rotates, it can push the two movable boxes away from each other and move closer to each other. During the movement of the movable boxes, the lever moves synchronously. Through the contact between the lever and the fixed block during the movement, the lever can also shake during the movement, which has a dispersing effect on the accumulated magnetic powder and can also break up the clumps of magnetic powder, making it convenient to remove impurities from the magnetic powder. Furthermore, the heat generated by the heating plate during the magnetic powder dispersion process is discharged through the heat exhaust holes, which is in contact with the magnetic powder and can ensure the dryness of the magnetic powder during the transportation process. 2. During the dispersion of magnetic powder, the suction force generated by the blower can draw floating powder and impurities in the magnetic powder into the fixed box through the feed hole. The impurities enter the movable box through the fixed hole and the through groove, and then are discharged along the air supply hose. The removal of impurities from the magnetic powder facilitates its subsequent processing. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To solve the problems existing in the prior art, this example provides the following technical solution: a conveying device for magnetic powder production, including a conveyor belt 1, side guard plates 2 on both sides of the conveyor belt 1, the side guard plates 2 having a limiting effect on the magnetic powder during the conveying process, and the inner side of the conveyor belt 1 being in contact with the surface of the magnetic plate 3, and a top plate 4 fixed between the two side guard plates 2, while the magnetic plate 3 is located directly below the top plate 4; it also includes: a cleanup mechanism, which is set on the top plate 4, the cleanup mechanism removes impurities by agitating the magnetic powder and generating suction force, and the cleanup mechanism and the magnetic plate 3 cooperate with each other to remove impurities.

[0019] When magnetic powder falls onto the conveying equipment, a large amount of magnetic powder accumulates. Its distribution on the conveying equipment is uneven, easily causing the magnetic powder to stick and clump together. There is a lack of a structure to disperse the magnetic powder. Figures 1-8As shown, the length and width of the magnetic plate 3 are both smaller than those of the top plate 4. A motor 5 is mounted on the upper surface of the top plate 4, and a connecting plate 6 is fixed to the output shaft of the motor 5. Guide wheels 7 are rotatably mounted on both ends of the connecting plate 6. The surfaces of the guide wheels 7 are in close contact with the sides of the movable boxes 8, and the two movable boxes 8 are connected to each other by springs. The movable boxes 8 slide against the inner wall of the support plate 9, while the support plate 9 is fixed to the lower surface of the top plate 4. The two movable boxes 8 move in opposite directions. The lower surface of the movable box 8 is glued to one end of the connecting hose 10, and a lever 11 is fixed to the other end of the connecting hose 10. The lever 11 is hollow. A gap is left between the bottom of the lever 11 and the conveyor belt 1, and both the connecting hose 10 and the lever 11 are evenly arranged on the movable box 8; the bottom of the lever 11 has a pre-reserved heat exhaust hole 12, and the lever 11 is interconnected with the interior of the strip box 13 through the connecting hose 10, and the strip box 13 is fixed to the inner bottom surface of the movable box 8, and adjacent movable boxes 8 are interconnected through a fixed pipe 14; the strip boxes 13 are evenly distributed in the movable box 8, and a heating plate is provided in the movable box 8 in the middle position, and the height of the strip box 13 is lower than the height of the internal cavity of the movable box 8; first, the magnetic powder is placed on the conveyor belt 1 for conveying, and when it is conveyed to the position below the top plate 4, the magnetic powder... The powder, attracted by the magnetism of the magnetic plate 3, adheres tightly to the surface of the conveyor belt 1. Then, the motor 5 drives the connecting plate 6 to rotate. The connecting plate 6 pushes the two movable boxes 8 away from each other. During this pushing process, the contact between the guide wheel 7 and the movable boxes 8 improves smoothness. As the movable boxes 8 move, the lever 11 moves synchronously. Therefore, through the continuous rotation of the connecting plate 6, the movable boxes 8 can continuously move away and closer together, causing the lever 11 to agitate the magnetic powder, dispersing it evenly. During this dispersion process, the heat generated by the heating plate enters the strip box 13, and is then transferred to different strip boxes 13 through the fixed tube 14, and finally through the connecting hose 10. The magnetic powder enters the lever 11, so when the magnetic powder is moved, heat can be discharged from the heat dissipation hole 12 and come into contact with the magnetic powder, which has a drying effect on it. Therefore, during the conveying process, it can break up the clumps of magnetic powder and ensure its dryness. As the magnetic powder is continuously conveyed, it separates from the position of the magnetic plate 3, which makes it convenient for the subsequent magnetic powder to fall down on its own for further processing without being magnetized. When the lever 11 moves, it can contact the fixing block 20 on the side of the fixing box 18. The contact between the two allows the lever 11 to shake when it moves, which improves the dispersion efficiency of the magnetic powder. Since the lever 11 is connected to the movable box 8 through the connecting hose 10, it will not affect the heat transfer and can automatically reset when not pushed.

[0020] Example 2: Since magnetic powder contains not only fine floating powder but also other impurities before processing, it needs to be removed before being conveyed to the processing equipment. However, most traditional conveying equipment lacks a structure for removing impurities from the magnetic powder, requiring an additional removal structure. Therefore, dust and other impurities may fall into the magnetic powder during conveying. This example addresses this issue by using the following technical solution: Figure 5 and Figures 7-10 As shown, the impurity removal mechanism includes a suction fan 15 at the edge of the top plate 4, and the output end of the suction fan 15 is connected to the interior of the movable box 8 through an air supply hose 16, and the air supply hose 16 slides through the top plate 4; the interior of the movable box 8 is connected to the interior of the fixed box 18 through a through groove 17 and a fixing hole 21, and both ends of the fixed box 18 are fixed to the side guard plate 2, and the length of the fixed box 18 is equal to the maximum distance between the two movable boxes 8; the through groove 17 is opened on the lower end face of the movable box 8, and the through groove 17 is set between two adjacent strip boxes 13, the fixing hole 21 is set on the top of the fixed box 18, and the bottom of the fixed box 18 is reserved with feed holes 19 at equal intervals, and the fixed hole 21 is set on the top of the fixed box 18, and the bottom of the fixed box 18 is reserved with feed holes 19 at equal intervals, and the fixed hole 21 is set on the bottom of the fixed box 18. Fixed blocks 20 are fixed at equal intervals on the side of the fixed box 18, and the fixed blocks 20 and the lever 11 are in close contact. While dispersing the magnetic powder, the suction fan 15 runs and generates suction, which can suck the floating powder and impurities in the dispersion process into the feed hole 19. Since the magnetic powder is attracted by the magnetic plate 3 and there is a gap between the feed hole 19 and the magnetic powder, the magnetic powder will not be sucked out. Then the impurities enter the movable box 8 through the fixed hole 21 and the through groove 17, and then are discharged along the air supply hose 16. The removal of impurities from the magnetic powder facilitates its subsequent processing. The movable plate 8 is always in contact with the surface of the fixed box 18 when it moves, so the through groove 17 and the fixed hole 21 can be connected without causing air leakage.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
