Description

Technical Field

[0001] This application belongs to the field of ball milling technology, specifically relating to a vibratory ball milling device. Background Technology

[0002] A vibratory ball mill typically includes a drive assembly, a vibration assembly, and a grinding jar connected in sequence. The drive assembly drives the vibration assembly to vibrate, and the vibration assembly drives the grinding jar to vibrate. When the grinding jar is filled with vibrating balls, the powder inside the jar is processed, including refining and modifying the powder.

[0003] In related technologies, counterweights are typically installed on the vibrating assembly. The weight of the counterweights provides counterweight force to the vibrating assembly, thereby lowering its center of gravity. However, the large weight of the counterweights increases the weight of the vibrating assembly and the power requirements of the drive assembly, which in turn increases the installation space of the drive assembly and the arrangement space of the vibrating assembly in the vibrating ball mill.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] A vibratory ball mill typically comprises a drive assembly, a vibrating assembly, and a grinding jar connected in sequence. The grinding jar usually contains grinding media to grind the material. Different proportions of grinding media are used depending on the powder volume of the material being ground, resulting in variations in the overall mass of the grinding jar. The grinding jar is usually positioned above the vibrating assembly, meaning the center of mass of the vibrating system (comprising the vibrating assembly and grinding jar) is not aligned with the center of mass of the vibrating assembly. This causes an uneven pulling force from the vibrating system to the drive assembly when it vibrates, potentially leading to drive assembly failure. Simultaneously, the vibrating system also experiences an uneven pulling force, causing its trajectory to deviate, reducing grinding efficiency and increasing noise. In related technologies, a counterweight is typically placed on the vibrating assembly. The weight of this counterweight adjusts the weight of the vibrating assembly, bringing the center of mass of the vibrating system closer to the center of rotation of the drive assembly. However, this method typically requires a large counterweight, resulting in a heavier and larger vibration assembly, which in turn increases its size and requires more installation space. Furthermore, the increased weight necessitates a higher power output from the drive assembly, further increasing its power requirement and thus its installation space. Additionally, since the weight of the grinding jar varies while the counterweight provides a constant force, even when grinding jars of different weights are used on the vibration assembly, the unchanging counterweight force means the center of mass of the entire vibration system will not be aligned with the axis of rotation of the drive assembly.

[0050] To address at least one of the aforementioned problems, this application provides a vibratory ball mill apparatus. The vibratory ball mill apparatus can be used to grind materials. The vibratory ball mill apparatus of this application will now be described in detail with reference to the accompanying drawings.

[0051] Reference Figures 1-8 The vibratory ball milling device provided in this application embodiment may specifically include: a base 1; a ball milling jar 2, which is used to contain the material to be ball milled; a vibration component 3, which is disposed on the base 1 and connected to the ball milling jar 2, and is used to drive the ball milling jar 2 to vibrate; a drive component 4, which is disposed on the base 1 and connected to the vibration component 3, and is used to drive the vibration component 3 to vibrate; and a magnetic counterweight component 5, which is disposed on the base 1 and spaced apart from the vibration component 3, and has a magnetic attraction force between the magnetic counterweight component 5 and the vibration component 3.

[0052] Specifically, the base 1 supports the vibration assembly 3, the drive assembly 4, and the magnetic counterweight assembly 5. The base 1 may include a first base plate 101 and a second base plate 102. The drive assembly 4 can be fixedly mounted on the first base plate 101, specifically through welding, bolting, or other methods. The vibration assembly 3 is mounted on the first base plate 101. The magnetic counterweight assembly 5 can be mounted on the second base plate 102. The first and second base plates 101 and 102 provide support for the drive assembly 4, the vibration assembly 3, and the magnetic counterweight assembly 5.

[0053] The ball mill jar 2 is used to hold the material to be ball milled. Appropriate grinding media can be added to the ball mill jar 2. The grinding media can include, but are not limited to, steel balls and ceramic balls to enhance the grinding effect.

[0054] The vibration assembly 3 drives the ball mill jar 2 to vibrate at high frequency, thereby causing the material inside the ball mill jar 2 to collide and rub against the grinding media, achieving the grinding purpose. The drive assembly 4 provides power to the vibration assembly 3, driving the vibration assembly 3 to vibrate.

[0055] In some embodiments, the vibration component 3 can be made of metal, and the magnetic counterweight component 5 can have a magnetic element, so that a magnetic attraction force is generated between the vibration component 3 and the magnetic counterweight component 5. Alternatively, the vibration component 3 can be provided with a magnetic element, and the magnetic counterweight component 5 can be provided with a metal element, so that a magnetic attraction force is generated between the vibration component 3 and the magnetic counterweight component 5. Or, both the magnetic counterweight component 5 and the vibration component 3 are provided with magnetic elements, and the polarities of the magnetic elements are opposite, which can also generate a magnetic attraction force between the vibration component 3 and the magnetic counterweight component 5. This magnetic attraction force can be used as the counterweight force of the vibration component 3 to adjust the counterweight of the vibration component 3.

[0056] In this embodiment, the vibration component 3 and the magnetic counterweight component 5 are arranged at intervals. The magnetic counterweight component 5 and the vibration component 3 have a magnetic attraction force. This magnetic attraction force can be used as the counterweight force of the vibration component 3, so there is no need to set a counterweight block on the vibration component 3, reducing the weight of the vibration component 3 and the power requirement for the drive component 4, thereby reducing the installation space of the drive component 4 of the vibrating ball mill device and the arrangement space of the vibration component 3.

[0057] Optionally, the magnetic counterweight assembly 5 includes a magnetic element 501, which is disposed on the base 1 and has a magnetic attraction force with the vibration assembly 3.

[0058] like Figures 2-4 As shown, the magnetic component 501 can be a permanent magnet, and the vibration assembly 3 can be made of metal. A magnetic attraction force is generated between the permanent magnet and the metal vibration assembly 3. Alternatively, the magnetic component 501 can be an electromagnet, and the vibration assembly 3 can be made of a magnetically conductive metal. By charging the electromagnet, a magnetic attraction force can be generated between the magnetic component 501 and the vibration assembly 3. The magnetic component 501 can be mounted on the second base plate 102 of the base 1. The magnetic attraction force between the magnetic component 501 and the vibration assembly 3 can be used as a counterweight force to adjust the weight of the vibration assembly 3. In practical applications, using the magnetic attraction force between the magnetic component 501 and the vibration assembly 3 as a counterweight force can reduce the weight of the vibration assembly 3 and the power requirements of the drive assembly 4, thereby reducing the installation space of the drive assembly 4 and the arrangement space of the vibration assembly 3.

[0059] In some alternative embodiments, there are multiple magnetic elements 501 arranged on the base 1.

[0060] like Figures 2-4 As shown, the magnetic element 501 can be composed of multiple magnetic elements 501, and these magnetic elements 501 are arranged on the base 1 according to a certain rule or order. The arrangement can be designed according to actual needs, such as linear arrangement, matrix arrangement, or other specific geometric arrangement.

[0061] In practical applications, by setting multiple magnetic components 501, the magnetic attraction between the magnetic components 501 and the vibration assembly 3 can be increased, thereby providing counterweight for the vibration assembly 3. Furthermore, when the mass of the grinding jar 2 is different, the magnetic attraction between the magnetic components 501 and the vibration assembly 3 can be changed by adjusting the number and arrangement of the magnetic components 501, resulting in different counterweight forces for the vibration assembly 3. This allows the vibratory ball milling device to adapt to grinding jars 2 with different mass ranges, improving the compatibility and utilization rate of the vibratory ball milling device.

[0062] In some alternative embodiments, a plurality of magnetic elements 501 are arranged in a Hellbeck array on the base 1.

[0063] Specifically, multiple magnetic components 501 are arranged on the second base plate 102 of the base 1 in a Hellbeck array manner. The Hellbeck array refers to the ability to enhance the magnetic field on one side and weaken or even completely cancel it out on the other side by setting the polarity direction of multiple magnetic components 501.

[0064] In this embodiment, based on the principle of the Hellbeck array, multiple magnetic components 501 are arranged on the second base plate 102 on the base 1 according to a specific polarity direction. This makes the magnetic field of the magnetic component 501 stronger on the side closer to the vibration component 3, and weaker or completely canceled on the side farther away from the vibration component 3. In this way, the magnetic field of multiple magnetic components 501 can be concentrated on the side closer to the vibration component 3, which improves the magnetic attraction force on that side. This makes the magnetic attraction force between the magnetic counterweight component 5 and the vibration component 3 more concentrated. This concentrated magnetic attraction force can better provide counterweight force for the vibration component 3. Furthermore, since the Hellbeck array can efficiently concentrate the magnetic field energy on the side closer to the vibration component 3, the same attraction effect can be achieved with fewer magnetic components 501, reducing the number of magnetic components 501 and thus reducing the weight and manufacturing cost of the vibratory ball mill device.

[0065] Optionally, the magnetic counterweight assembly 5 includes a magnetic attraction group 50 and a moving assembly 51. The magnetic attraction group 50 includes a plurality of magnetic elements 501. The magnetic attraction group 50 is connected to the moving assembly 51, and the moving assembly 51 is connected to the base 1. The moving assembly 51 drives the magnetic attraction group 50 to move so that the magnetic attraction group 50 moves closer to or further away from the vibration assembly 3.

[0066] like Figures 1-4 As shown, the magnetic attraction group 50 includes a plurality of magnetic components 501. The magnetic components 501 can refer to the aforementioned embodiments and will not be described in detail here.

[0067] The magnetic attraction assembly 50 can be fixedly mounted at one end of the movable component 51. The other end of the movable component 51 is fixedly mounted on the second base plate 102 of the base 1. The movable component 51 can drive the magnetic attraction assembly 50 to move, so that the magnetic attraction assembly 50 moves closer to or further away from the vibration component 3. That is, the distance between the magnetic attraction assembly 50 and the vibration component 3 can be adjusted by the movable component 51. The closer the magnetic component 501 of the magnetic attraction assembly 50 is to the vibration component 3, the greater the magnetic attraction force between them, that is, the greater the counterweight force. The farther the magnetic component 501 of the magnetic attraction assembly 50 is from the vibration component 3, the smaller the magnetic attraction force between them, that is, the smaller the counterweight force.

[0068] In practical applications, by adjusting the distance between the magnetic suction group 50 and the vibration component 3 using the moving component 51, the magnetic attraction force between the magnetic component 501 and the vibration component 3 can be changed, that is, the counterweight force of the vibration component 3 can be changed. In this way, even if the mass of the ball mill jar 2 is different, the counterweight force of the vibration component 3 can be adjusted by the moving component 51, so that the vibratory ball milling device can be adapted to ball mill jars 2 with different mass ranges, thereby improving the compatibility and utilization rate of the vibratory ball milling device.

[0069] Optionally, the moving component 51 includes a mounting plate 511, a first driving member 512, a first moving block 513, and a second moving block 514; the mounting plate 511 is spaced apart from the vibration component 3, and the magnetic suction group 50 is disposed on the mounting plate 511; the first moving block 513 is connected to the mounting plate 511; the second moving block 514 is connected to the base 1; one end of the first driving member 512 is connected to the base 1, and the other end of the first driving member 512 is connected to the first moving block 513, and the first moving block 513 is slidably connected to the second moving block 514; the first driving member 512 drives the first moving block 513 to move on the second moving block 514, so as to drive the mounting plate 511 and the magnetic suction group 50 to move.

[0070] Specifically, the magnetic suction assembly 50 is fixedly mounted on one side of the mounting plate 511, which can be achieved through mechanical fixing, adhesive bonding, or other methods. The first moving block 513 is fixedly mounted on the other side of the mounting plate 511, and the second moving block 514 is fixedly mounted on the other side of the second mounting plate 511 of the base 1. The first moving block 513 is a first wedge-shaped block, and the second moving block 514 is a second wedge-shaped block, with the shapes of the first and second wedge-shaped blocks being compatible.

[0071] The first moving block 513 is slidably connected to the second moving block 514. One end of the first driving member 512 is fixedly connected to the second base plate 102 of the base 1, and the other end is connected to the second moving block 514. The first driving member 512 drives the first moving block 513 to slide on the second moving block 514. The first moving block 513 drives the mounting plate 511 to move, and the mounting plate 511 drives the magnetic suction group 50 to move, thereby adjusting the distance between the magnetic suction group 50 and the vibration component 3, and thus adjusting the magnetic attraction force between the magnetic suction group 50 and the vibration component 3, i.e., adjusting the counterweight force of the vibration component 3. In this way, the counterweight force of the vibration component 3 can be automatically adjusted. The automatic adjustment function can adjust the counterweight force in real time according to specific needs, so that the vibrating ball mill device can adapt to the mass of various ball mill jars 2 and improve the versatility of the vibrating ball mill device.

[0072] Furthermore, the first drive component 512 can be an electric actuator, a pneumatic actuator, or the like.

[0073] In some alternative embodiments, the mounting plate 511 is a weak magnetic mounting plate 511 or a non-magnetic mounting plate 511, that is, the mounting plate 511 is made of a weak magnetic material or a non-magnetic material. In practical applications, by using a weak magnetic or non-magnetic material for the mounting plate 511, it can be ensured that the magnetic field of the magnetic absorbing assembly 50 is not affected by the mounting plate 511, thereby maintaining the original adsorption performance of the magnetic absorbing assembly 50 and allowing the magnetic field of the magnetic absorbing assembly 50 to act on the vibration component 3 more efficiently.

[0074] In some alternative embodiments, the moving component 51 further includes a plurality of guide posts 515, one end of which is connected to the base 1 and the other end of which is slidably connected to the mounting plate 511. The guide posts 515 are used to guide the movement of the mounting plate 511.

[0075] like Figures 2-4 As shown, the moving component 51 includes multiple guide posts 515, which are evenly and spaced on the second base plate 102 of the base 1. One end of each guide post 515 is fixedly connected to the second base plate 102, and the other end is slidably connected to the mounting plate 511. In this way, when the first driving component 4 drives the mounting plate 511 to move, the multiple guide posts 515 can guide the movement of the mounting plate 511, making the movement of the mounting plate 511 and the magnetic suction group 50 more stable.

[0076] like Figures 1-4 As shown, in some optional embodiments, the magnetic suction assembly 50 and the moving assembly 51 are spaced apart from the vibration assembly 3 along the first direction Z, and the driving assembly 4 is arranged opposite to the vibration assembly 3 along the second direction Y, wherein the first direction Z intersects the second direction Y.

[0077] Specifically, such as Figure 1 and Figure 4 As shown, the first direction Z is the Z-axis direction, which specifically refers to the height direction of the vibratory ball mill device, and the second direction Y is the Y-axis direction. The first direction Z and the second direction Y intersect. In this embodiment, the first direction Z and the second direction Y are perpendicular.

[0078] The grinding jar 2 is located above the vibration assembly 3 along the first direction Z. The magnetic suction group 50 and the moving component 51 are located below the vibration assembly 3 along the first direction Z. The top of the magnetic suction group 50 along the first direction Z is a certain distance from the bottom of the vibration assembly 3 along the first direction Z. By moving the moving component 51, the magnetic suction group 50 is moved closer to or further away from the vibration assembly 3 along the first direction Z. The distance between the magnetic suction group 50 and the vibration assembly 3 along the first direction Z can be adjusted, thereby adjusting the counterweight force of the vibration assembly 3 downward along the first direction Z, so that the center of mass of the vibration assembly 3 is consistent with the center of mass of the vibration assembly 3 and the grinding jar as a whole.

[0079] The drive component 4 and the vibration component 3 are arranged opposite each other along the second direction Y. The output end of the drive component 4 and the input end of the vibration component 3 are located on the same horizontal plane in the second direction Y, so that the output end of the drive component 4 can be connected to the input end of the vibration component 3. The drive component 4 can drive the vibration component 3 to vibrate, and the vibration component 3 can drive the ball mill jar 2 to vibrate, thereby realizing the grinding of the material to be ground in the ball mill jar 2.

[0080] In some alternative embodiments, a height sensor and a controller are also included. The height sensor is connected to the vibration component 3, and the controller is connected to the height sensor and the moving component 51. The height sensor is used to detect the height value of the vibration component 3 along the first direction Z and transmit it to the controller. The controller is used to control the moving component 51 to drive the magnetic suction group 50 to move according to the height value.

[0081] Specifically, the controller is connected to the height sensor and the moving component 51. The height sensor is fixedly connected below the input end of the vibration component 3 along the first direction Z. The height sensor can measure the height value of the input end of the vibration component 3 along the first direction Z and feed this height value back to the controller. The controller compares the height value fed back by the height sensor with the calibrated height value to determine whether the magnetic attraction force between the magnetic suction group 50 and the vibration component 3 is sufficient. If it is insufficient, the controller will send a signal to the first drive member 512 in the moving component 51. The first drive member 512 drives the magnetic suction group 50 located on the mounting plate 511 of the moving component 51 to move along the first direction Z, adjusting the distance between the magnetic suction group 50 and the vibration component 3, thereby adjusting the magnetic attraction force between the magnetic suction group 50 and the vibration component 3, that is, adjusting the counterweight force of the vibration component 3. In this way, the counterweight of the vibration component 3 can be automatically adjusted. The automatic adjustment function can adjust the counterweight in real time according to specific needs, so that the vibratory ball mill can adapt to the mass of various ball mill jars 2, improve the versatility of the vibratory ball mill, reduce reliance on manual labor, improve the convenience of operation, and reduce the possibility of human error.

[0082] In some alternative embodiments, the drive assembly 4 includes a second drive member 40 and a coupling 41; the second drive member 40 and the vibration assembly 3 are disposed opposite to each other on the base 1 along a second direction Y; the second drive member 40 has an output shaft 401, the vibration assembly 3 is provided with an input shaft 33, and the output shaft 401 is connected to the input shaft 33 through the coupling 41.

[0083] like Figure 1 , Figure 5 , Figure 6As shown, the second drive unit 40 has an output shaft 401 with a fixed flange. The fixed flange is connected to the coupling 41 by fasteners. The input shaft 33 of the vibration assembly 3 typically has a fixed flange, which is also connected to the coupling 41 by fasteners. When the output shaft 401 of the second drive unit 40 rotates, it drives the input shaft 33 of the vibration assembly 3 to rotate via the coupling 41. The rotation of the input shaft 33 of the vibration assembly 3 causes the vibration assembly 3 to produce elliptical or circular vibrations. This type of vibration can act more evenly on the material in the ball mill jar 2, improving the ball milling efficiency and effect. Furthermore, the second drive unit 40 is a drive motor, and the coupling 41 is a flexible coupling 41.

[0084] Optionally, the vibration assembly 3 includes a vibrating plate 30, multiple buffers 31, and a counterweight 32; the vibrating plate 30 and the base 1 are spaced apart along the first direction Z; the ball mill jar 2 is connected to the side of the vibrating plate 30 away from the base 1; the two ends of the buffers 31 are respectively connected to the vibrating plate 30 and the base 1; the counterweight 32 is disposed on the side of the vibrating plate 30 away from the base 1, and the input shaft 33 is rotatably connected to the counterweight 32.

[0085] like Figure 1 , Figures 5-8 As shown, a ball mill jar 2 is provided on the top surface of the vibrating plate 30 along the first direction Z, and a counterweight 32 is connected to the bottom surface of the vibrating plate 30 along the first direction Z. The input shaft 33 is rotatably connected to the counterweight 32. The buffer 31 is a spring. The vibrating plate 30 and the first base plate 101 of the base 1 are respectively provided with protrusions. One end of the spring is sleeved on the protrusion on the vibrating plate 30, and the other end of the spring is sleeved on the protrusion on the first base plate 101. Multiple springs are arranged around the counterweight 32. The number of buffers 31 can be multiple, and can be selected according to the actual situation. In this embodiment, four buffers 31 are used as an example.

[0086] like Figure 7 and Figure 8 As shown, the eccentric component 32 includes an eccentric shell 320 and an eccentric block 321. A portion of the input shaft 33 passes through the eccentric shell 320 and is rotatably connected to the eccentric shell 320. The portion of the input shaft 33 located inside the eccentric shell 320 is fixedly connected to the eccentric block 321. The first driving component 512 drives the input shaft 33 to rotate, and the input shaft 33 drives the eccentric block 321 to rotate, causing the eccentric shell 320, the vibrating plate 30, the buffer component 31, and the ball mill jar 2 to produce elliptical or circular vibrations. This vibration pattern can act more evenly on the material inside the ball mill jar 2, improving the ball milling efficiency and effect.

[0087] The number and shape of the eccentric blocks 321 can be specifically set according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0088] In summary, the vibratory ball mill apparatus of this application embodiment may include at least the following advantages:

[0089] In this embodiment, the vibration component 3 and the magnetic counterweight component 5 are spaced apart. The magnetic counterweight component 5 and the vibration component 3 have a magnetic attraction force, which can be used as the counterweight force of the vibration component 3. Therefore, it is not necessary to set a counterweight block on the vibration component 3, thereby reducing the weight of the vibration component 3 and the power requirement for the drive component 4, and further reducing the installation space of the drive component 4 and the arrangement space of the vibration component 3 in the vibratory ball mill device.
