Description
Technical Field
[0001] This utility model relates to the field of mixing tank technology, specifically a neodymium iron boron high-speed mixing machine. Background Technology
[0002] With societal development, the application of neodymium iron boron (NdFeB) magnets is becoming increasingly widespread. NdFeB magnets, also known as neodymium magnets, are tetragonal crystals formed from neodymium, iron, and boron. They are currently the second strongest permanent magnets after holmium magnets at absolute zero, and are also the most commonly used rare-earth magnets. NdFeB magnets are divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB magnets exhibit magnetism in all directions and are corrosion-resistant, while sintered NdFeB magnets are prone to corrosion and require a surface coating. To achieve optimal magnetic performance, the magnetic powder needs to be thoroughly mixed to ensure uniform magnetic properties. Mixing also allows for a more reasonable particle size distribution, resulting in better magnetic performance. Furthermore, mixing ensures a more uniform surface treatment of the magnetic powder, leading to better corrosion resistance.
[0003] The existing patent publication number CN221156240U discloses a neodymium iron boron magnetic powder mixing tank. The lifting rod can drive the support plate to move up, and then the support plate drives the stirring shaft to move up. At the same time, the first scraper moves up along the inclined plate and presses the elastic auxiliary rod and the first elastic rod to retract inward. Thus, the first scraper and the second scraper can work together with the stirring rod to stir at the same time, thereby improving the stirring efficiency.
[0004] When the above-mentioned patent is used, the tank remains fixed, and the neodymium iron boron is located inside the tank and is only stirred by the first scraper, the second scraper and the stirring rod. It cannot guarantee efficient turning of the neodymium iron boron. Stirring alone cannot guarantee efficient and comprehensive mixing, which reduces the mixing efficiency. At the same time, when the material is discharged from the outlet by opening the solenoid valve at the bottom, it is slow and cannot guarantee that the discharge is clean and thorough. Utility Model Content
[0005] The purpose of this invention is to provide a high-speed NdFeB mixer to solve the problems mentioned in the background art, such as the inability to guarantee efficient turning of NdFeB, the inability to guarantee efficient and comprehensive mixing by stirring alone, which reduces the mixing efficiency, and the slow discharge from the outlet by opening the solenoid valve at the bottom, which cannot guarantee clean and thorough discharge.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed NdFeB mixer, comprising two support frames, an inner support cover, a mixing tank, and a tank cover. The inner support cover is fixedly connected to the lower inner side of the two support frames. An adjusting assembly is movably installed inside the two support frames and the inner support cover. A stirring assembly is movably installed inside the tank cover. The adjusting assembly includes a turntable movably installed within the two support frames. A gear one located inside the support frame is fixedly connected to the inner side of the turntable. A gear two meshing with gear one is movably installed inside the inner support cover. A motor is fixedly installed and connected to gear two for transmission. An eccentric rod is fixedly connected to the outer side of the turntable. A transmission rod is movably installed on the outer side of the eccentric rod. A slider is movably installed on the other end of the transmission rod. A sliding groove is opened on the inner side of the support frame. A transmission box is fixedly installed on the inner side of the slider. A fixed frame is movably installed on the inner side of the transmission box. A cylinder and a rack fixedly connected to the top of the cylinder are fixedly installed inside the transmission box. Gear three located inside the transmission box and meshing with the rack are fixedly connected to the left and right sides of the fixed frame. The mixing tank is fixedly installed on the inner side of the fixed frame.
[0007] Preferably, the transmission rod is rotatably connected to the outside of the slider and the eccentric rod, respectively.
[0008] Preferably, the slider is engaged inside the groove, and the slider is slidably connected within the groove.
[0009] Preferably, the cylinder is located inside the transmission box at the bottom, and the rack meshes with the outer side of the gear three.
[0010] Preferably, the stirring assembly includes a second motor fixedly installed at the bottom of the mixing tank, a rotating shaft located inside the mixing tank fixedly installed outside the output shaft of the second motor, a stirring rod and a limiting sleeve fixedly installed outside the rotating shaft, and a stirring frame fixedly installed outside the limiting sleeve.
[0011] Preferably, the stirring rack is fitted to the inner wall of the mixing tank, and the outer side of the stirring rack is provided with an inclined surface.
[0012] Preferably, the can lid is movably installed on the top of the mixing tank, and the stirring rods are staggered and equidistantly arranged.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The motor drives the gear 2 to rotate, and the gear 1 drives the turntable to rotate. The slider moves back and forth in the chute, causing the powder in the mixing tank to tumble up and down. The control cylinder pushes the rack to move up and down, which drives the gear 3 to rotate, thereby driving the fixed frame to rotate the mixing tank. This changes the tilt angle of the mixing tank and promotes the tumbling of the powder in multiple directions. Combined with the stirring effect of the stirring component, this ensures the high efficiency of the mixing process and improves the uniformity and efficiency of the mixing.
[0015] 2. The cylinder drives the rack to move, which in turn causes the gear three to rotate, causing the fixed frame and the mixing tank to tilt. The upper end of the mixing tank tilts downwards, and the motor two starts, causing the rotating shaft to rotate. The rotating shaft then causes the stirring rack, which is close to the inner wall of the mixing tank, to rotate, thereby scraping off the powder adhering to the tank. The powder is then quickly discharged from the upper end of the mixing tank, effectively improving the discharge efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a high-speed NdFeB mixer, comprising two support frames 1, an inner support cover 2, a mixing tank 3, and a tank cover 4. The inner support cover 2 is fixedly connected to the lower inner side of the two support frames 1. An adjustment assembly 5 is movably installed inside the two support frames 1 and the inner support cover 2. A stirring assembly 6 is movably installed inside the tank cover 4. The adjustment assembly 5 includes a turntable 51 movably installed inside the two support frames 1. A gear 52 located inside the support frame 1 is fixedly connected to the inner side of the turntable 51. The inner support cover 2... A gear 53 is movably mounted to mesh with gear 52. A motor 54, which is connected to gear 53, is fixedly mounted inside the inner support cover 2. An eccentric rod 55 is fixedly connected to the outside of the turntable 51. A transmission rod 56 is movably mounted on the outside of the eccentric rod 55. A slider 57 is movably mounted on the other end of the transmission rod 56. A groove 58 is opened on the inner side of the support frame 1. A transmission box 59 is fixedly mounted on the inner side of the slider 57. A fixing frame 510 is movably mounted on the inner side of the transmission box 59. A cylinder is fixedly mounted inside the transmission box 59. 511 and a rack 513 fixedly connected to the top of cylinder 511. Gears 512, located inside transmission box 59 and meshing with rack 513, are fixedly connected to the left and right sides of the fixed frame 510. The mixing tank 3 is fixedly installed inside the fixed frame 510. The motor 54 drives gear 53 to rotate. Gear 53, in conjunction with gear 52, drives turntable 51 to rotate. The rotation of turntable 51 drives eccentric rod 55 to rotate, causing transmission rod 56 to push and pull slider 57 to slide back and forth in slide groove 58, so that the mixing tank... The powder inside the mixing tank 3 is turned up and down. At the same time, the control cylinder 511 can drive the rack 513 to move upward along the transmission box 59. The upward movement of the rack 513 pushes the gear 3 512 that meshes with it to rotate. The gear 3 512 drives the fixed frame 510 to rotate. The fixed frame 510 drives the mixing tank 3 to rotate and tilt at different angles, so that the powder inside is turned up in different directions. In conjunction with the stirring component 6, the powder is turned up and stirred at different positions to ensure high efficiency of mixing and improve the uniformity and efficiency of mixing.
[0024] The transmission rod 56 is rotatably connected to the outside of the slider 57 and the eccentric rod 55 respectively. The rotation of the turntable 51 drives the eccentric rod 55 to rotate, causing the transmission rod 56 to push and pull the slider 57 to slide back and forth in the groove 58. This works in conjunction with the stirring action of the stirring component 6 to form efficient powder agitation in the mixing tank 3, changing the position and frequency of contact between the powder and the stirring component 6, allowing the stirring component 6 to stir the powder more comprehensively and meticulously, thereby further improving the uniformity of powder mixing.
[0025] The slider 57 is locked inside the slide groove 58. The slider 57 is slidably connected within the slide groove 58, which makes the movement of the slider 57 within the slide groove 58 stable and smooth, effectively reducing the jamming phenomenon during the movement. The slide groove 58 plays a good limiting role for the slider 57, ensuring that the slider 57 can only slide back and forth along a specific trajectory, thereby ensuring the stability of the movement.
[0026] The cylinder 511 is located inside the transmission box 59 at the bottom. The rack 513 meshes with the outer side of the gear 3 512. The cylinder 511 can provide stable power to drive the rack 513 to move. The rack 513 and the gear 3 512 mesh with each other. The linear motion of the rack 513 drives the gear 3 512 to rotate. The rotation of the gear 3 512 further transmits power, causing the mixing tank 3 to rotate. By setting the mixing tank 3 vertically or horizontally, the powder is fully turned over, ensuring the high efficiency of the mixing work.
[0027] Please see Figure 3 , Figure 5 The mixing assembly 6 includes a second motor 61 fixedly installed at the bottom of the mixing tank 3. A rotating shaft 62 located inside the mixing tank 3 is fixedly installed outside the output shaft of the second motor 61. A stirring rod 63 and a limiting sleeve 64 are fixedly installed outside the rotating shaft 62. A stirring frame 65 is fixedly installed outside the limiting sleeve 64. After mixing, the tank cover 4 is opened, and the rack 513 is driven to move by the cylinder 511, which in turn causes the gear 3 512 to rotate, causing the fixed frame 510 and the mixing tank 3 to tilt. The upper end of the mixing tank 3 tilts downward. The second motor 61 is started, causing the rotating shaft 62 to rotate. The rotating shaft 62 then causes the stirring frame 65, which is close to the inner wall of the mixing tank 3, to rotate, thereby scraping off the powder adhering to the tank. The powder is quickly discharged from the upper end of the mixing tank 3, effectively improving the discharge efficiency.
[0028] The mixing rack 65 is attached to the inner wall of the mixing tank 3. An inclined surface 66 is provided on the outer side of the mixing rack 65. The inclined surface 66 forms a certain angle with the inner wall of the mixing tank 3, so that the powder can be scraped off by the inclined surface 66 during the rotation of the mixing rack 65, which improves the effect of scraping off the powder and makes the discharge process more efficient and thorough.
[0029] The tank lid 4 is movably installed on the top of the mixing tank 3. The stirring rods 63 are staggered and equidistantly arranged to ensure comprehensive mixing and reduce dead zones. When the staggered and equidistantly distributed stirring rods 63 rotate, the powder in different positions can be evenly stirred, further improving the uniformity of the mixture. The tank lid 4 can be disassembled for easy loading and unloading before and after mixing, as well as subsequent maintenance.
[0030] Working principle: During use, different powders are added to the mixing tank 3 and the tank lid 4 is closed. Then, the control motor 61 drives the rotating shaft 62 to rotate, which in turn drives the stirring rod 63 and the stirring frame 65 to mix the powders. Simultaneously, the control motor 54 drives the gear 53 connected to both sides to rotate. The gear 53 meshes with the gear 52, which is coaxial with the turntable 51, thus driving the turntable 51 to rotate efficiently. The rotation of the turntable 51 drives the eccentric rod 55 to rotate, which in turn drives the transmission rod 56 to push and pull the slider. 57 slides back and forth inside the chute 58, causing the powder inside the mixing tank 3 to tumble up and down. At the same time, the control cylinder 511 can drive the rack 513 to move upward along the transmission box 59. The upward movement of the rack 513 pushes the gear 3 512 that meshes with it to rotate. The gear 3 512 is installed on both sides of the fixed frame 510, thereby driving the fixed frame 510 to rotate. The fixed frame 510 drives the mixing tank 3 to rotate and tilt at different angles, causing the powder inside to tumble up and down in different directions, thereby improving the efficiency, uniformity and efficiency of mixing.
[0031] After the powder is mixed, the can lid 4 is opened. Then, the cylinder 511 drives the rack 513 to rotate, which in turn drives the gear 512 to rotate, thereby tilting the fixed frame 510 and the mixing tank 3 inside, so that the top of the mixing tank 3 tilts downward. The motor 61 drives the rotating shaft 62 to rotate, which in turn drives the stirring rack 65, which is attached to the inner wall of the mixing tank 3, to rotate. The rotation of the stirring rack 65 scrapes off the powder adhering to the inside of the mixing tank 3, and the powder is quickly discharged outward along the top of the mixing tank 3, improving the discharge efficiency. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
