Description

Technical Field

[0001] This invention relates to the field of magnet raw material feeding technology, and more specifically, to a magnet raw material feeding mechanism and its usage method. Background Technology

[0002] Magnets are typically made from metallic elements such as iron, cobalt, and nickel, as well as some rare earth metals. Magnets can be made from these metallic elements alone or in combination, or from magnetic materials such as ferromagnetic substances.

[0003] In the existing technology, the raw materials need to be stirred and crushed when producing magnets. Therefore, the amount of magnet raw materials needs to be controlled to facilitate subsequent production. The existing magnet raw material feeding device cannot achieve quantitative feeding of magnet raw materials. There is a problem that the magnet raw materials are piled up due to excessive feeding, which affects the feeding speed and thus affects production.

[0004] Therefore, we have made improvements to this by proposing a magnetic raw material feeding mechanism and its usage method. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing magnetic raw material feeding devices cannot achieve quantitative feeding of magnetic raw materials, resulting in accumulation due to excessive magnetic raw material feeding, which affects the feeding speed and thus production.

By using a combination of a rotating component and a sensing component, a fixed amount of magnetic raw material is positioned above the sliding plate inside the storage box. Under the action of the pushing component, the magnetic raw material is fed into the mixer for mixing and crushing, thus achieving a fixed amount of magnetic raw material feeding and preventing accumulation due to excessive magnetic raw material feeding, which would affect the feeding speed.

[0013] As a preferred embodiment of the magnetic raw material feeding mechanism and its usage method provided by the present invention, the pulling member includes a mounting plate 1, which is fixedly connected to the bottom side of one end of the rotating plate. Two mounting plates 1 are mirror images of each other. A motor 2 is fixedly connected to one side of the outer surface of the mounting plate 1. The output end of the motor 2 extends to the space between the two mounting plates 1 and two gears 1 are fixedly connected. Two racks are provided below the sliding plate, and the racks are matched with the gears 1.

[0014] In a preferred embodiment of the magnetic raw material feeding mechanism and its usage method provided by the present invention, the sensing element includes a mounting block that extends into the interior of the storage box and is fixedly connected to the rotating plate. A sealing plate 2 is slidably connected inside the first slide groove, and the sealing plate 2 is fixedly connected to the upper surface of the mounting block. A sealing plate 3 is fixedly connected to the bottom side of the outer surface of the mounting block. A spring 1 is fixedly connected to the upper surface of the mounting block, and the top end of the spring 1 is fixedly connected to the mounting plate 2. The mounting plate 2 is fixedly connected to the outer surface of the storage box. A connecting block is fixedly connected to one side of the outer surface of the mounting block. A curved toothed plate is slidably connected to the outer surface of the storage box on the side of the sealing plate 3, and a proximity switch is fixedly connected to the outer surface of the curved toothed plate.

[0015] As a preferred embodiment of the magnet raw material feeding mechanism and its usage method provided by the present invention, the adjusting component includes a second gear and a protective plate. The protective plate is located on the outer surface of the storage box. The second gear meshes with the curved toothed plate. The second gear is rotatably connected to the storage box through a rotating shaft. A rotating knob is fixedly connected to the rotating rod through the protective plate. A scale is provided at the edge of the outer surface of the protective plate. An arc-shaped groove that slides with the curved toothed plate is provided on the side of the protective plate near the sealing plate.

[0016] As a preferred embodiment of the magnetic raw material feeding mechanism and its usage method provided by the present invention, a second sliding groove is provided on the outer surface of the storage box on one side of the curved toothed plate, a fixed toothed plate is slidably connected to the inner surface of the second sliding groove, the bottom side of the fixed toothed plate is matched with the second gear, and a third sliding groove is provided on the surface of the protective plate above the rotating knob, and the fixed toothed plate is slidably disposed inside the third sliding groove.

[0017] As a preferred embodiment of the magnetic raw material feeding mechanism and its usage method provided by the present invention, a slide block is fixedly connected to one side of the slide block, a spring two is fixedly connected to the inner surface of the slide block, a slider is fixedly connected to one end of the spring two, the slider is slidably disposed with the slide block, and the slider is located on the top side of the fixed toothed plate extending into the interior of the slide block.

[0018] A method of using a magnetic raw material feeding mechanism, comprising the aforementioned magnetic raw material feeding mechanism, is as follows:

[0019] During use, the adjusting component enables the adjustment of the weight of the magnetic raw material. By using the rotating component and the sensing component together, a fixed amount of magnetic raw material is placed above the sliding plate inside the storage box. Under the action of the pushing component, the magnetic raw material is put into the mixer for mixing and crushing, thereby realizing the quantitative feeding of magnetic raw material and preventing the accumulation of magnetic raw material due to excessive feeding, which would affect the feeding speed.

[0020] When quantitative feeding of the magnet material is required, move the slider to the right to disengage it from the top surface of the slide groove three, extending from the fixed toothed plate. Move the fixed toothed plate upwards to the top of slide grooves two and three, thus disengaging the fixed toothed plate from gear two. Release the slider, allowing it to move to the left under the force of spring two, returning it to its original position while simultaneously supporting the top fixed toothed plate to prevent it from sliding down. Rotate the knob to rotate gear two, as gear two meshes with the curved toothed plate. The curved toothed plate and the arc-shaped groove on the side of the protective plate are slidably set, thereby driving the curved toothed plate to slide relative to each other. The relative position of the proximity switch on the scale is observed to determine the quantitative feeding of the magnetic raw material. The slider is moved to the right to disengage from the surface of the fixed toothed plate. The fixed toothed plate is moved downward to the bottom of the slide groove three, thereby realizing the meshing relationship between the fixed toothed plate and the gear two. The gear two is fixed. The slider is released, and the slider is pushed to the left by the elastic force of the spring two to lock the slider at the top of the fixed toothed plate.

[0021] In operation, the motor initially drives the conveyor belt. The operator pours the magnetic material between the baffles on the upper surface of the conveyor belt. Under the action of the baffles, the magnetic material moves into the storage box. The magnetic material falls onto the upper surface of the sliding plate. Due to its own weight, the magnetic material pushes the sliding plate, causing the rotating plate to rotate around the connecting rod. The second sealing plate slides inside the first groove, simultaneously causing the mounting block and the connecting block fixedly connected to the mounting block to rotate synchronously. When the connecting block contacts the proximity switch, the proximity switch triggers a signal, and motor one stops working, thus stopping the feeding of the magnetic material. Then, motor two is started, driving gear one to rotate synchronously. Because gear one is meshed with the rack, from... Pulling the sliding plate outwards causes the magnetic material on the surface of the sliding plate to fall from the center of the rotating plate into the mixer for mixing and crushing. After the magnetic material is fed, the rotating plate is reset by the elastic force of spring one. According to the pre-programmed settings, after motor two moves to the far right, gear one automatically rotates in the opposite direction to reset the rotating plate. Then, motor one starts working to feed the next batch of material. Because sealing plates two and three are set on the inner and outer sides of the storage box to block the sliding groove one during the falling process, and the upper surface of sealing block one and the lower surface of rotating plate one end, and the outer surface of rotating plate one end and the inner surface of storage box are provided with matching curved surfaces, the outward dispersion of magnetic material and dust is reduced.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The adjustment mechanism allows for the regulation of the weight of the magnetic raw material. By using a combination of a rotating component and a sensing component, a fixed amount of magnetic raw material is positioned above the sliding plate inside the storage box. Under the action of the pushing component, the magnetic raw material is fed into the mixer for mixing and crushing, thus achieving a fixed amount of magnetic raw material feeding and preventing accumulation due to excessive magnetic raw material feeding, which would affect the feeding speed.

[0046] Example 1

[0047] Please refer to Figure 1-8A magnetic material feeding mechanism and its usage method are disclosed, comprising a feeding rack 1 and a mixer 15. A motor 11 is fixedly connected to one side of the outer surface of the feeding rack 1. The output end of the motor 11 passes through the feeding rack 1 and is connected to a conveyor belt 12 via a synchronous pulley. Several baffles 13 are fixedly connected to the outer surface of the conveyor belt 12. A storage box 14 is fixedly connected to the lower surface of the feeding rack 1. The storage box 14 is sealed to the mixer 15. A rotating component for storing magnetic materials is rotatably connected inside the storage box 14. A pulling component is fixedly connected below the rotating component. Slide grooves 41 are provided on both sides of the outer surface of the storage box 14. A sensor for triggering induction when the magnetic material is quantitatively measured is slidably arranged on the inner surface of the slide grooves 41. An adjusting component for controlling the amount of magnetic material is rotatably connected to the side of the outer surface of the storage box 14 located at the sensor. The adjusting components include a second gear 52 and a protective plate 54. The protective plate 54 is located on the outer surface of the storage box 14. The second gear 52 meshes with the curved toothed plate 47 and is rotatably connected to the storage box 14 via a rotating shaft. A rotating knob 53 is fixedly connected to the rotating rod through the protective plate 54. A scale 55 is provided on the edge of the outer surface of the protective plate 54. An arc-shaped groove is provided on the side of the protective plate 54 near the sealing plate 43, which slides with the curved toothed plate 47. A second groove 51 is provided on the outer surface of the storage box 14 on one side of the curved toothed plate 47. A fixed toothed plate 5 is slidably connected to the inner surface of the second groove 51. The bottom side of the fixed toothed plate 5 matches the second gear 52. A third groove 56 is provided on the surface of the protective plate 54 above the rotating knob 53. The fixed toothed plate 5 slides inside the third groove 56. A slide block 6 is fixedly connected to one side of the slide block 56. A spring 61 is fixedly connected to the inner surface of the slide block 6.

The slider 62 is slidably disposed with the slide block 6, and the slider 62 is located on the top side of the fixed toothed plate 5 extending into the interior of the slide block 56.

[0048] Implementation process: When it is necessary to feed the magnet raw material in a quantitative manner, move the slider 62 to the right to disengage it from the top surface of the slide groove 56, which is extended from the fixed tooth plate 5. Move the fixed tooth plate 5 upward to the top of the slide groove 51 and the slide groove 56, thereby disengaging the fixed tooth plate 5 and the gear 52. Release the slider 62, and under the elastic force of the spring 61, the slider 62 will move to the left to return to its original position, while supporting the fixed tooth plate 5 on the top side to prevent it from moving downward. Turn the knob 53 to drive the gear 52 to rotate, because the gear 52 meshes with the curved tooth plate 47. The curved toothed plate 47 and the arc-shaped groove on the side of the protective plate 54 are connected and slidably set, thereby driving the curved toothed plate 47 to slide relative to each other. The relative position of the proximity switch 48 on the scale 55 is observed to determine the quantitative feeding of the magnetic raw material. The slider 62 is moved to the right to disengage from the surface of the fixed toothed plate 5. The fixed toothed plate 5 is moved downward to the bottom of the slide groove 56, thereby realizing the meshing relationship between the fixed toothed plate 5 and the gear 2 52. The gear 2 52 is fixed. The slider 62 is released, and the slider 62 is pushed to the left by the elastic force of the spring 2 61, so that the slider 62 is locked at the top of the fixed toothed plate 5.

[0049] Benefits of implementation: It enables quantitative feeding of magnet raw materials.

A slot 23 is provided on one side of the outer surface of the storage box 14. A rotating plate 21 is rotatably connected to the outer surface of the connecting rod 2. A sliding plate 22 is slidably connected inside the rotating plate 21. A sealing block 24 is fixedly connected to the bottom side of the inner surface of the slot 23. The upper surface of the sealing block 24 has a curved surface that matches the lower surface of the rotating plate 21. A curved surface that matches the inner surface of the storage box 14 is also provided on one side of the outer surface of the rotating plate 21. The pulling component includes a mounting plate 3, which is fixedly connected to the bottom side of one end of the rotating plate 21. Two mounting plates 3 are mirror images of each other. A motor 31 is fixedly connected to one side of the outer surface of the mounting plate 3. The output end of the motor 31 extends to the space between the two mounting plates 3 and is fixedly connected to two gears 32. Two racks 33 are provided below the sliding plate 22 and are matched with the gears 32. The sensing element includes a mounting block 4, which extends into the interior of the storage box 14 and is fixedly connected to the rotating plate 21. A sealing plate 42 is slidably connected inside the slide groove 41 and is fixedly connected to the upper surface of the mounting block 4. A sealing plate 43 is fixedly connected to the bottom side of the outer surface of the mounting block 4. A spring 44 is fixedly connected to the upper surface of the mounting block 4.

[0052] Implementation process: Motor 11 starts working, driving the conveyor belt 12 to rotate. The worker pours the magnetic material between the baffles 13 on the upper surface of the conveyor belt 12. Under the action of the baffles 13, the magnetic material moves to the inside of the storage box 14. The magnetic material falls on the upper surface of the sliding plate 22. Due to the gravity of the magnetic material itself, the sliding plate 22 pushes the rotating plate 21 to rotate around the connecting rod 2. The sealing plate 42 slides inside the sliding groove 41, simultaneously driving the mounting block 4 and the connecting block 46 fixedly connected to the mounting block 4 to rotate synchronously. When the connecting block 46 contacts the proximity switch 48, the proximity switch 48 triggers a signal, and Motor 11 stops working, thereby stopping the feeding of the magnetic material. Then, Motor 2 31 is started. Motor 2 31 drives the gear 32 to rotate synchronously. Because the gear 32 meshes with the rack 33... The connection is made so that the sliding plate 22 is pulled to slide outward, so that the magnetic material on the surface of the sliding plate 22 falls from the center of the rotating plate 21 into the mixer 15 for mixing and crushing. After the magnetic material is fed, the rotating plate 21 is reset under the elastic force of the spring 44. According to the pre-program setting, after the motor 31 moves to the rightmost position, the gear 32 automatically rotates in the opposite direction to reset the rotating plate 21. Then the motor 11 starts to work for the next feeding. Because the sealing plate 42 and the sealing plate 43 are set on the inner and outer sides of the storage box 14 to block the sliding groove 41 during the falling process, and the upper surface of the sealing block 24 and the lower surface of one end of the rotating plate 21, and the outer surface of one end of the rotating plate 21 and the inner surface of the storage box 14 are provided with matching curved surfaces, the outward dispersion of magnetic material and dust is reduced.

[0053] Benefits of implementation: It enables sensing when the magnetic material feeding is completed, reducing the dispersion of magnetic material and dust.

By using the combination of the rotating component and the sensing component, a fixed amount of magnetic raw material is placed above the sliding plate (22) inside the storage box (14). Under the action of the pushing component, the magnetic raw material is put into the mixer (15) for stirring and crushing, thereby realizing the fixed feeding of the magnetic raw material and preventing the accumulation of too much magnetic raw material from affecting the feeding speed. When it is necessary to feed the magnet raw material in a quantitative manner, move the slider (62) to the right so that the slider (62) is disengaged from the fixed tooth plate (5) and extends to the top surface inside the slide groove three (56). Move the fixed tooth plate (5) upward so that the fixed tooth plate (5) moves to the top of the slide groove two (51) and the slide groove three (56), thereby disengaging the fixed tooth plate (5) and the gear two (52). Release the slider (62) so that the slider (62) is pushed to the left by the elastic force of the spring two (61) to return to its original position. At the same time, it supports the fixed tooth plate (5) on the top side so that it does not move down. Turn the rotating knob (53) to drive the gear two (52) to rotate. Because the gear two (52) is meshed with the curved tooth plate (47), The curved toothed plate (47) and the arc-shaped slot on the side of the protective plate (54) are slidably set, thereby driving the curved toothed plate (47) to slide relative to each other. The relative position of the proximity switch (48) on the scale (55) is observed, thereby determining the quantitative feeding of the magnetic raw material. The slider (62) is moved to the right to disengage the slider (62) from the surface of the fixed toothed plate (5). The fixed toothed plate (5) is moved downward to move the fixed toothed plate (5) to the bottom of the slide groove three (56), thereby realizing the meshing relationship between the fixed toothed plate (5) and the gear two (52). The gear two (52) is fixed. The slider (62) is released, and the slider (62) is pushed to the left by the elastic force of the spring two (61) to lock the slider (62) at the top of the fixed toothed plate (5). When in use, motor one (11) starts working and drives the conveyor belt (12) to rotate. The operator pours the magnetic material between the baffles (13) on the upper surface of the conveyor belt (12). Under the action of the baffles (13), the magnetic material is moved to the inside of the storage box (14). The magnetic material falls on the upper surface of the sliding plate (22). Due to the gravity of the magnetic material itself, the sliding plate (22) is pushed to drive the rotating plate (21) to rotate around the connecting rod (2). The sealing plate two (42) slides inside the slide groove one (41), and at the same time drives the mounting block (4) and the connecting block (46) fixedly connected to the mounting block (4) to rotate synchronously. When the connecting block (46) contacts the proximity switch (48), the proximity switch (48) triggers a signal, and motor one (11) stops working, thereby stopping the feeding of the magnetic material. Then motor two (31) is started. Motor two (31) drives gear one (32) to rotate synchronously. Because gear one (32) and rack The meshing connection of (33) pulls the sliding plate (22) to slide outward, so that the magnetic material on the surface of the sliding plate (22) falls from the center of the rotating plate (21) into the mixer (15) for stirring and crushing. After the magnetic material is fed, the rotating plate (21) is reset under the elastic force of the spring (44). In the early program setting, after the motor (31) moves to the rightmost side, the gear (32) automatically rotates in the opposite direction to reset the rotating plate (21). Then the motor (11) starts to work for the next feeding. Because the sealing plate (42) and the sealing plate (43) are set on the inner and outer sides of the storage box (14) to block the sliding groove (41) during the falling process, and the upper surface of the sealing block (24) and the lower surface of one end of the rotating plate (21), and the outer surface of one end of the rotating plate (21) and the inner surface of the storage box (14) are provided with matching curved surfaces, which reduces the outward dispersion of magnetic material and dust.
