Description

Technical Field

[0001] This application relates to the field of vibratory ball mill technology, and more particularly to a vibratory ball mill. Background Technology

[0002] A vibratory ball mill is a highly efficient grinding device, commonly used for operations such as crushing, mixing, homogenization, and mechanical alloying. Existing vibratory ball mills typically consist of a vibratory table assembly and a base, with springs connecting the two. The vibratory table assembly vibrates under the drive of a motor or other drive components, which in turn causes the grinding jar mounted on the vibratory table assembly to vibrate accordingly.

[0003] However, the weight of the grinding jar varies with each operation, resulting in different spring deformations. This causes a positional difference between the vibration table assembly and the drive components. Excessive positional difference disrupts the regular movement of the vibration table assembly, leading to significant noise during vibration. Furthermore, irregular vibrations occur during start-up and shutdown, which can negatively impact the motor's lifespan. Utility Model Content

[0044] The embodiments of this utility model will now be described in detail. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0045] A vibratory ball mill is a highly efficient powder processing equipment, mainly used for processes such as crushing, mixing, homogenization, and mechanical alloying. It uses high-frequency vibration to generate strong impact, friction, and shear forces on the grinding media (such as steel balls, ceramic balls, etc.) within the mill jar, thereby achieving the crushing and mixing of materials. The mill jar is the container that holds the materials and grinding media, and is usually made of wear-resistant materials (such as stainless steel, ceramic, or polymer materials). The volume and shape of the mill jar are designed according to the characteristics of the materials being processed, and can be cylindrical, square, or other special shapes. The mill jar is usually mounted on the vibrating table assembly of the vibratory ball mill. The vibrating table assembly vibrates under the drive of motors, electric cylinders, pneumatic cylinders, hydraulic cylinders, hydraulic motors, etc., which in turn causes the mill jar to vibrate. To ensure that the vibrating table assembly can move freely during vibration, it is usually mounted on a base using springs, i.e., the springs support the base and the vibrating table assembly.

[0046] However, the operational requirements of a vibratory ball mill vary with each operation. Correspondingly, the volume and weight of the grinding jar also change. The size of the grinding balls and the ratio of grinding balls to the powder to be processed also differ. This leads to variations in the load applied to the vibratory table assembly by the grinding jar. Since the stiffness of the springs in the vibratory table assembly is constant, their deformation varies with each operation due to load changes. This results in positional differences or eccentricities between the vibratory table assembly and its driving components. Excessive positional differences or eccentricities disrupt the regular movement of the vibratory table assembly, causing significant noise during vibration. Furthermore, irregular vibrations occur during start-up and shutdown, which can significantly impact the lifespan of the driving components.

[0047] To address the aforementioned problems, this application provides a vibratory ball mill.

[0048] refer to Figure 1 The vibratory ball mill provided in this embodiment specifically includes a base 1, a vibratory table assembly 2, a grinding jar 3, an adjustment mechanism 4, and a compression spring 5. The base 1 is the component used to place on an external bearing surface and provide a mounting base for other parts of the vibratory ball mill. The specific structure, shape, and dimensions of the base 1 can be determined according to actual needs, and will not be elaborated here.

[0049] refer to Figure 2 , Figure 3The vibration table assembly 2 is a component used to mount the grinding jar 3 and provide vibration to the grinding jar 3. In this embodiment, the vibration table assembly 2 may specifically include a jar-shaped structure 25 and a support platform 26 welded together. A rotating shaft is connected inside the jar-shaped structure 25, and an eccentric wheel or pendulum is mounted on the rotating shaft. The rotating shaft extends outside the jar structure to connect with driving components such as a motor or hydraulic motor. Driven by the driving component, the eccentric wheel or pendulum rotates with the rotating shaft and continuously generates vibration. The vibration is transmitted to the grinding jar 3 mounted on the support platform 26 via the support platform 26. The grinding jar 3 vibrates synchronously with the support platform 26, causing the grinding balls inside the grinding jar 3 to squeeze and rub the powder to be processed. To improve the structural strength of the vibration table assembly 2 and prevent welding failure between the jar-shaped structure 25 and the support platform 26, reinforcing ribs 27 or reinforcing ribs can be connected between the support platform 26 and the jar-shaped structure 25 to increase the connection area and the connection strength between the support platform 26 and the jar-shaped structure 25. Of course, the specific structure of the vibration table assembly 2 is not limited to the vibration table assembly 2 described in the embodiments of this application, and other vibration table assembly 2 structures can also be used, which will not be elaborated here.

[0050] The grinding jar 3 is a container used to hold the powder to be processed. The size and shape of the grinding jar 3 can be determined according to actual needs. The grinding jar 3 generally contains grinding balls such as steel balls or ceramic balls. When the grinding jar 3 vibrates with the vibration table assembly 2, the grinding balls inside the grinding jar 3 move relative to the grinding jar and simultaneously squeeze and rub the powder to be processed.

[0051] refer to Figure 4 , Figure 5 The adjustment mechanism 4 is mounted on the base 1 and has a movable part 4a that can move relative to the base 1. The movement direction of the movable part 4a is set along a first direction X, which is in the same direction as the axis of the compression spring 5. The first end of the compression spring 5 is fixedly connected to the vibration table assembly 2, and the second end of the compression spring 5 is drivenly connected to the movable part 4a of the adjustment mechanism 4. When the weight of the grinding jar 3 changes, the load applied to the compression spring 5 by the grinding jar 3 and the vibration table assembly 2 also changes. At this time, the compression spring 5 will generate a deformation along its own axis, that is, a deformation along the first direction X, and this deformation will change with the load on the compression spring 5. At this time, by driving the adjustment mechanism 4 to move, the movable part 4a of the adjustment mechanism 4 will move along the first direction X, thereby keeping the vibration table assembly 2 in a preset position.

[0052] Specifically, when the weight of the grinding jar 3 increases, the load applied to the compression spring 5 by the grinding jar 3 and the vibration table assembly 2 also increases. At this time, the force on the compression spring 5 in its own axial direction increases, and the deformation of the compression spring 5 also increases accordingly. Then, the moving part 3a of the adjusting mechanism 4 moves along the first direction X towards the vibration table assembly 2 to keep the rotation axis of the vibration table assembly 2 aligned with the driving component of the vibration table assembly 2 in the first direction X. Alternatively, when the weight of the grinding jar 3 decreases, the load applied to the compression spring 5 by the grinding jar 3 and the vibration table assembly 2 also decreases. At this time, the force on the compression spring 5 in its own axial direction decreases, and the deformation of the compression spring 5 also decreases accordingly. Then, the moving part 3a of the adjusting mechanism 4 moves along the first direction X towards the base 1 to keep the rotation axis of the vibration table assembly 2 aligned with the driving component of the vibration table assembly 2 in the first direction X.

[0053] This ensures that there is no positional difference or eccentricity between the rotation axis of the vibration table assembly 2 and the driving component that drives the vibration table assembly 2. This prevents the regular movement of the vibration table assembly 2 from being disturbed by positional differences or eccentricity, and avoids excessive noise during vibration. Furthermore, at start and stop, the vibration table assembly 2 is less prone to irregular vibrations due to positional differences or eccentricity, thus preventing these differences or eccentricities from significantly impacting the lifespan of the mechanism driving the vibration table assembly 2.

[0054] refer to Figure 8 , Figure 10 , Figure 11 In some embodiments of this application, the adjustment mechanism 4 specifically includes a first driving member 41, a lead screw 42, and a nut 43. The first driving member 41 is fixedly connected to the base 1 and is also drively connected to the lead screw 42. The lead screw 42 is rotatably mounted on the base 1, and the nut 43 is threadedly connected to the lead screw 42. Simultaneously, the nut 43 is fixedly connected to the second end of the compression spring 5. The nut 43 is the moving part 4a of the aforementioned adjustment mechanism 4.

[0055] Driven by the first driving member 41, the lead screw 42 can rotate relative to the base 1. Since the nut 43 is fixedly connected to the second end of the compression spring 5, the nut 43 will not rotate synchronously with the lead screw 42. At this time, under the threaded engagement between the nut 43 and the lead screw 42, the nut 43 can move along the axial direction of the lead screw 42. The axial direction of the lead screw 42 is preferably coaxially connected with the axial direction of the compression spring 5. At this time, the compression spring 5, the vibration table assembly 2, and the grinding jar 3 are driven by the nut 43 to move along the first direction X, thereby realizing the adjustment of the position of the vibration table assembly 2.

[0056] refer to Figure 8 , Figure 10 , Figure 11A first protrusion 431 may be provided on the nut 43. The first protrusion 431 may be columnar and fixedly inserted into the second end of the compression spring 5 to achieve a fixed connection between the nut 43 and the second end of the compression spring 5. Correspondingly, a second protrusion 28 may also be provided on the vibration table assembly 2, and the second protrusion 28 on the vibration table assembly 2 is opposite to the first protrusion 431 on the nut 43 in the first direction X. The second protrusion 28 on the vibration table assembly 2 is also columnar and fixedly inserted into the first end of the compression spring 5 to achieve a fixed connection between the compression spring 5 and the vibration table assembly 2. The first protrusion 431 and the second protrusion 28 can facilitate the installation of the compression spring 5 and provide guiding support for the compression of the compression spring 5 to prevent the compression spring 5 from tilting or misaligning during compression. Of course, other methods can also be used to fix the compression spring 5 and the vibration table assembly 2, as well as the compression spring 5 and the nut 43. For example, the compression spring 5 and the vibration table assembly 2, as well as the compression spring 5 and the nut 43, are fixedly connected by means of bonding, welding, etc.

[0057] refer to Figure 1 In some embodiments of this application, at least two compression springs 5 ​​are provided. The number of compression springs 5 ​​can specifically be two, three, four, or even more. The at least two compression springs 5 ​​are spaced apart to provide support at different positions on the vibration table assembly 2. Having at least two compression springs 5 ​​can distribute the load on a single compression spring 5, thereby reducing the deformation of a single compression spring 5 under load. When the weight of the grinding jar 3 changes, since this weight change is supported by at least two compression springs 5, the deformation change on a single compression spring 5 is significantly reduced. This helps to reduce positional changes in the vibration table assembly 2.

[0058] refer to Figure 8 Based on this, at least two lead screws 42 and nuts 43 are also provided, with the number of lead screws 42 and nuts 43 corresponding to the number of compression springs 5. Each nut 43 is fixedly connected to one of the compression springs 5 ​​and threadedly connected to one lead screw 42. At least two lead screws 42 are positioned corresponding to the positions of the compression springs 5, and the first driving member 41 is drivenly connected to at least two lead screws 42. This arrangement allows one first driving member 41 to drive at least two lead screws 42 to rotate, thereby adjusting the positions of at least two compression springs 5. Compared to the technical solution of a single first driving member 41 driving a single lead screw 42, the above arrangement can effectively simplify the mechanism of the vibratory ball mill while adjusting the positions of at least two compression springs 5, reducing the space occupation and cost of the vibratory ball mill.

[0059] refer to Figure 8 , Figure 9In some embodiments of this application, the adjusting mechanism 4 further includes a transmission wheel 44 and a transmission belt 45. At least two transmission wheels 44 are provided, and each transmission wheel 44 is coaxially and fixedly connected to a lead screw 42. The transmission belt 45 is simultaneously connected to the driving part of the first driving member 41 and to the at least two transmission wheels 44, so that the first driving member 41 can simultaneously drive at least two transmission wheels 44 to rotate, thereby driving at least two lead screws 42 to rotate. This helps ensure that the torque output by the first driving member 41 can act synchronously on the transmission wheels 44, and that the transmission is smooth, reliable, and has a strong load capacity.

[0060] refer to Figure 8 In this embodiment, the transmission wheel 44 is preferably a gear, and the transmission belt 45 is preferably a synchronous belt that meshes with the gear. During installation, the transmission belt 45 is wrapped around the driving part of the first driving member 41 and the outside of all the transmission wheels 44, so that the power output by the first driving member 41 can be synchronously transmitted to all the transmission wheels 44. Of course, the transmission belt 45 can also be a common belt or a V-belt, etc. Correspondingly, the transmission wheels 44 can also be transmission wheels 44 adapted to the transmission belt 45.

[0061] refer to Figure 12 In some embodiments of this application, the base 1 includes a receiving cavity 11 and an opening 12 that are interconnected. The drive wheel 44 and the drive belt 45 are both located within the receiving cavity 11. Specifically, the base 1 may have a mounting hole 13, which is also connected to the receiving cavity 11. The lead screw 42 can be mounted in the mounting hole 13 via a bearing, and the drive wheel 44 is mounted on the portion of the lead screw located in the receiving cavity 11. The drive belt 45 extends into the receiving cavity 11 from the opening 12 and is connected to the drive wheel 44 in a driving connection. The arrangement of the receiving cavity 11 allows the drive wheel 44 and the drive belt 45 to be integrated inside the base 1, thus saving space occupied by the vibratory ball mill. The opening 12 facilitates the installation of the lead screw 42, drive wheel 44, and drive belt 45, and also allows technicians to easily observe the operating status of the lead screw 42, drive wheel 44, and drive belt 45.

[0062] In this embodiment, preferably, four compression springs 5 ​​are arranged in a matrix of two rows and two columns, and are evenly supported between the vibration table assembly 2 and the base 1. Four lead screws 42, four nuts 43, and four drive wheels 44 are also provided corresponding to the number of compression springs 5. For any compression spring 5, its end facing the base is fixedly connected to a nut 43. Each nut 43 is threaded onto a lead screw 42; each lead screw 42 is rotatably mounted on the base 1 and fixedly mounted with a drive wheel 44. One drive belt 45 is provided, which is simultaneously connected to the four drive wheels 44 and the drive part of the first drive member 41, so as to transmit the movement of the drive part of the first drive member 41 to the drive wheels 44. That is, the moving part of the first drive member 41 can drive the drive belt 45 to move, thereby driving the four drive wheels 44 to rotate synchronously.

[0063] refer to Figure 1 , Figure 2 In some embodiments of this application, the vibratory ball mill further includes a second drive member 6 and a flexible coupling 7.

[0064] The second driving component 6 is fixedly connected to the base 1, and a flexible coupling 7 connects the driving part of the second driving component 6 and the power input end of the vibration table assembly 2. The flexible coupling 7 can overcome small-range eccentricity or positional difference between the second driving component 6 and the vibration table assembly 2, so as to ensure that the transmission between the second driving component 6 and the vibration table assembly 2 is not affected when the vibration table vibrates. In this embodiment, the second driving component 6 is preferably an electric motor or a hydraulic motor.

[0065] refer to Figure 1 , Figure 2 In some embodiments of this application, the flexible coupling 7 includes connecting pieces 71. At least two connecting pieces 71 are provided, specifically two, three, four, or even more. The connecting pieces 71 are arranged at intervals around the axis of the driving part of the second driving member 6. Simultaneously, the first end of all connecting pieces 71 is fixedly connected to the driving part of the second driving member 6, and the second end of all connecting pieces 71 is fixedly connected to the power input end of the vibration table assembly 2. When the vibration table assembly 2 includes a rotating shaft and a pendulum, the power input end of the vibration table assembly 2 is one end of the rotating shaft. When the second driving member 6 is a motor, the driving part of the second driving member 6 is the output shaft of the motor. The flexible coupling 7 includes at least two connecting pieces 71, which on the one hand ensures the structural strength of the flexible coupling 7, making the transmission between the second driving member 6 and the vibration table assembly 2 more reliable; on the other hand, it also helps to simplify the structure of the flexible coupling 7, thereby reducing the cost of the vibratory ball mill.

[0066] refer to Figure 6 , Figure 7In some embodiments of this application, the vibration table assembly 2 includes a first mounting plate 21 and a second mounting plate 22. The first mounting plate 21 and the second mounting plate 22 are spaced apart to form a mounting space 2a for mounting the ball mill jar 3. (See reference...) Figure 3 , Figure 4 Both the first mounting plate 21 and the second mounting plate 22 are inclined relative to the first direction X. The distance between the end of the first mounting plate 21 furthest from the base 1 and the end of the second mounting plate 22 furthest from the base 1 is L1, and the distance between the end of the first mounting plate 21 closest to the base 1 and the end of the second mounting plate 22 closest to the base 1 is L2, where L1 is greater than L2. In this embodiment, the dimension of L1 can be set according to actual needs. Preferably, in this embodiment, L1 ≥ 261 mm, and 0 < L2 ≤ 76 mm. In other words, L1 can be any distance value not less than 261 mm, such as 261 mm, 270 mm, or 300 mm, and L2 can be any distance value not greater than 76 mm but greater than 0 mm, such as 1 mm, 50 mm, or 76 mm.

[0067] Preferably, refer to Figure 4 L1 is greater than or equal to the maximum outer diameter of the grinding jar 3, and L2 is less than the maximum outer diameter of the grinding jar 3. In other words, the installation space 2a between the first mounting plate 21 and the second mounting plate 22 has a V-shaped or trapezoidal cross-section. The dimension of the installation space 2a at the end furthest from the substrate is greater than the dimension at the end closest to the substrate. This ensures that the receiving cavity 11 between the first mounting plate 21 and the second mounting plate 22 can still accommodate the grinding jar 3 even when the size of the grinding jar 3 changes. The arrangement of the first mounting plate 21 and the second mounting plate 22 facilitates the installation of the grinding jar 3 and also allows for the adaptation of grinding jars 3 of different sizes. This improves the compatibility of the vibration table assembly 2 with grinding jars 3 of different sizes, thereby expanding the applicability of the vibratory ball mill.

[0068] refer to Figure 6 , Figure 7In some embodiments of this application, the vibration table assembly 2 further includes pressure blocks 23. Two pressure blocks 23 are provided, and each pressure block 23 has a mounting groove 231. The two pressure blocks 23 can be closed together so that the mounting grooves 231 of the two pressure blocks 23 can form a mounting cavity 24 for mounting the grinding jar 3. After the two pressure blocks 23 are closed together, they are simultaneously fixedly installed in the mounting space 2a between the first mounting plate 21 and the second mounting plate 22, so that the grinding jar 3 can be fixedly mounted on the vibration table assembly 2. When the grinding jar 3 changes, the size or spacing of the two pressure blocks 23 can be adjusted to adapt the space of the receiving cavity 11 to the change of the grinding jar 3. This further improves the adaptability of the vibration table assembly 2 to grinding jars 3 of different sizes, which is beneficial to improving the applicability of the vibratory ball mill. In this embodiment, the pressure blocks 23 can be bound together with the first mounting plate 21 and the second mounting plate 22 using structures such as threads, belts, and chains to achieve the installation of the pressure blocks 23. The shape of the pressure block 23 can be set according to actual needs. In this embodiment, the pressure block 23 can be a block structure with a semi-circular cross-section, and the mounting groove 231 is a semi-circular groove coaxial with the pressure block 23. After the two pressure blocks 23 are closed, the two mounting grooves 231 can be combined to form a cylindrical mounting cavity 24.

[0069] In some embodiments of this application, the vibratory ball mill also includes a position sensor. The position sensor is fixedly connected to the vibration table assembly 2 and detects the position of the vibration table assembly 2. When the position sensor detects an eccentricity or positional difference between the vibration table assembly 2 and the second drive member 6, it can send a detection signal to assist technicians in adjusting the height of the vibration table assembly 2. Specifically, when the second drive member 6 is a motor, the position sensor can detect the eccentricity between the rotating shaft of the vibration table assembly 2 and the output shaft of the second drive member 6. The position sensor can be a wire-type displacement sensor, a photoelectric sensor, an ultrasonic sensor, etc., which will not be listed in detail here.

[0070] In addition, a controller can also be installed on the vibratory ball mill. The controller can be electrically connected to the position sensor and the first drive component 41 respectively. After receiving the detection signal sent by the position sensor, the controller can determine whether there is an eccentricity or positional difference between the vibration table assembly 2 and the second drive component 6. If so, the controller can control the movement of the first drive component 41, thereby causing the nut 43 to move relative to the lead screw 42, so as to ensure the alignment between the vibration table assembly 2 and the second drive component 6.

[0071] refer to Figure 1In this embodiment, the ball mill jar 3 includes a jar body 31 and an electrode 32. The jar body 31 is a structure for accommodating the grinding balls and the powder to be processed. The electrode 32 is mounted on the jar body 31, and at least a portion of the electrode 32 extends into the interior of the jar body 31. The electrode 32 is electrically connected to an external plasma power source. The jar body 31 is filled with a protective gas, typically a stable gas such as nitrogen or helium. When a high voltage is applied to the electrode 32 and the jar body 31, plasma is generated within the jar body 31. Plasma is an ionized gas containing high-energy electrons, ions, active free radicals, and ultraviolet radiation, exhibiting high chemical activity and energy. When plasma bombards the surface of the powder to be processed, it can remove oxides or contaminants from the particle surface, exposing fresh active sites. Simultaneously, plasma can also induce lattice defects such as vacancies and dislocations in the powder to be processed, thereby reducing the energy threshold of mechanical processing such as ball milling. Under the synergistic effect of plasma bombardment and ball milling, the material processing efficiency of the vibratory ball mill can be significantly improved. Meanwhile, vibratory ball mills can also achieve grain refinement and specific functional modification.

[0072] Specifically, in this embodiment, the electrode 32 can be a rod-shaped structure, with one end extending into the canister 31 and the other end protruding outside the canister 31 for connection to an external power source. The canister 31 is evacuated and then filled with a protective gas. To prevent short circuits between the electrode 32 and the canister 31, and to increase the creepage distance between the canister 31 and the electrode 32, an insulating structure can be provided on the outside of the electrode 32. The insulating structure can be an insulating layer coated on the surface of the electrode 32, such as a Teflon layer, or an insulating shell, such as a ceramic shell, fitted over the electrode.
