Description

Technical Field

[0001] This invention relates to the field of ball milling machinery and equipment, and in particular to a high-efficiency planetary ball mill that facilitates the replacement of transmission components. Background Technology

[0002] Planetary ball mills are essential equipment for mixing, fine grinding, small sample preparation, nanomaterial dispersion, new product development, and small-batch production of high-tech materials. These products are small in size, feature-rich, and highly efficient, making them ideal for research institutions, universities, and enterprise laboratories to obtain microparticle research samples (up to six samples per experiment). They are widely used in geology, mining, metallurgy, electronics, building materials, ceramics, chemical, light industry, pharmaceutical, cosmetic, and environmental protection sectors, essentially covering nearly 60% of domestic electronic component manufacturers.

[0003] The working principle of a planetary ball mill is to utilize the high-speed tumbling of abrasive and sample within the grinding jar, generating strong shearing, impact, and crushing forces to achieve the purpose of pulverizing, grinding, dispersing, and emulsifying materials. As the planetary ball mill's rotor rotates, the grinding jar revolves around the rotor's axis while simultaneously rotating on its own axis, performing planetary motion. The grinding balls within the jar collide with each other during this high-speed motion, grinding and mixing the sample. This product can grind and mix products of different particle sizes and materials using both dry and wet methods, offering high efficiency and high performance. The minimum particle size of the ground product can reach 0.1 micrometers or even nanometers, effectively meeting various process parameter requirements.

[0004] Planetary ball mills mainly include the following types: vertical planetary ball mills, horizontal planetary ball mills, and omnidirectional planetary ball mills (tilting type). Vertical planetary ball mills have the grinding jar placed vertically and are suitable for crushing general materials. The latter two types of planetary ball mills are placed horizontally or the main unit is rotated during grinding. In addition to the planetary motion force of the machine, gravity also plays a role in the grinding of materials, resulting in higher grinding efficiency. They are suitable for materials with high density, large differences in specific gravity between the material and the grinding media, and materials that are prone to settling. They can effectively solve the problem of material caking and agglomeration.

[0005] Vertical planetary ball mills rotate around the geometric center axis of the grinding jar during grinding. The crushing of materials is mainly achieved through the grinding action between the grinding balls and the abrasive, and the impact force is not significant. This can lead to incomplete grinding and the formation of powder caking at the bottom of the jar. Horizontal ball mills are difficult to operate when adding and removing materials, and the equipment is not easy to clean and maintain. Tilting ball mills have complicated fixing operations, and the grinding jar is prone to shaking and even falling off during the grinding process. In addition, the drive components of tilting ball mills are complicated to install. The drive structure rotates with the planetary gear system, which increases the cost and energy consumption of the tilting unit. The power supply line of the planetary gear system drive is also unstable due to the rotation during tilting. Summary of the Invention

[0006] To address the shortcomings of the existing technologies, the present invention aims to provide a segmented planetary gear train, which facilitates disassembly, maintenance, and component replacement. Simultaneously, the grinding jar is connected by snap-fit ​​components for easy installation and disassembly, and the jar cover and body are sealed and opened via a turntable, facilitating the cleaning of materials inside the jar. Furthermore, the grinding jar mechanism utilizes a flipping mechanism to switch between horizontal and vertical placement, improving the efficiency of material handling and grinding, thereby solving the problems existing in the prior art.

[0007] The technical solution adopted by the present invention to achieve the above objectives is as follows: A high-efficiency planetary ball mill that facilitates the replacement of transmission components includes a casing, on which a tilting mechanism is mounted; The planetary gear train mechanism includes a revolution part and a rotation part, which mesh with each other and are both mounted on a tilting mechanism; Multiple ball mill jar mechanisms are all connected to the rotating part and rotate together with the rotating part; The power mechanism is located below the multiple ball mill jar mechanisms and provides a power source to the planetary gear train mechanism.

[0008] A further preferred embodiment of the present invention is: the revolution part is a sun gear, and the rotation part is a plurality of planet gears, which are evenly distributed on the outer periphery of the sun gear and meshed with the sun gear.

[0009] A further preferred embodiment of the present invention is that the planetary gear train mechanism further includes a gear ring fixing part, which is connected to the flipping mechanism and meshes with multiple planetary gears, thereby limiting the multiple planetary gears by the gear ring fixing part.

[0010] A further preferred embodiment of the present invention is as follows: the gear ring fixing part includes a plurality of gear rings, the plurality of gear rings are assembled into a ring, each gear ring is connected to the flipping mechanism through a spring positioning block, and the inner side of the gear ring cooperates with a plurality of planetary gears.

[0011] A further preferred embodiment of the present invention is that the planetary gear train mechanism further includes a pressure plate, a lever, and a central drive rod. The lever is located at the center of the sun gear, and the central drive rod is locked by the pressure plate pressing the lever.

[0012] A further preferred embodiment of the present invention is as follows: a mounting hole is formed at the center of the sun gear, and a limiting groove is provided on the central drive rod corresponding to the lever part. One end of the lever part is located on the outer periphery of the mounting hole, and the other end is located in the limiting groove and cooperates with the central drive rod.

[0013] Furthermore, by adopting the above scheme, each ball mill jar mechanism includes a fixed base and a jar body. The bottom of the fixed base is connected to the rotating part, and a fastening element is provided between the jar body and the fixed base. The jar body is detachably connected to the fixed base through the fastening element.

[0014] By adopting the above solution, the fastener further includes a chuck and multiple latches. The chuck is movably inserted into the fixed base through multiple connecting rods. The multiple latches are correspondingly set with the multiple connecting rods, and the multiple latches penetrate the outer shell of the fixed base and are latched onto the tank body.

[0015] Furthermore, by adopting the above scheme, a groove is opened around the tank body corresponding to the multiple latches, and the multiple latches are engaged in the groove, and each latch and each connecting rod are engaged with a bevel.

[0016] By adopting the above solution, the tank body further includes a tank body, a tank cover, and a turntable component. The tank body is installed in a fixed base, the tank cover is installed on the top of the tank body, and the turntable component is connected to the tank cover. The turntable component drives the tank cover to rotate to open or close the tank body.

[0017] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial effects: 1. This invention features a planetary gear train mechanism consisting of a sun gear and six planetary gears that engage with each other. Three evenly spaced gear rings confine the six planetary gears within the rings. These three gear rings are connected and fixed to a fixed plate via spring positioning blocks, facilitating the disassembly and maintenance of certain components. Furthermore, a lever structure is positioned at the center of the sun gear. Under the action of a pressure plate, the other end of the lever presses upward against the central drive rod, locking it in place. This engagement structure allows for a larger clearance fit between the central drive rod and the sun gear, aiding in the disassembly, assembly, and maintenance of these components.

[0018] 2. This invention features multiple grinding jar mechanisms, each with a rotating locking structure on its lid. By pressing down and simultaneously rotating a turntable, the lid rotates. A positioning rod connected to the turntable is inserted into a positioning hole in the jar body, thus locking the lid to the jar body. A sloping structure with a chuck and buckle is provided between the jar body and the fixed base. Pressing the chuck causes the connecting rod at the bottom of the chuck to contact the buckle and pushes the buckle outward from the fixed base, allowing the buckle to disengage from the fixed base and the jar body to be removed. This mechanism facilitates the placement and removal of the grinding jars, effectively improving assembly and disassembly efficiency.

[0019] 3. By setting up a flipping mechanism, the present invention enables multiple ball mill jars installed on the flipping mechanism to switch between horizontal and vertical states as needed. In the horizontal state, it is convenient to disassemble and assemble the ball mill jars, which is helpful for picking up and putting down materials and cleaning the ground materials. In the vertical state, the materials and grinding media are fully mixed and efficiently tumbled, which can improve the ball milling effect. The setting of this flipping mechanism avoids the instability caused by the traditional drive components rotating with the ball mill jars, which can ensure that the equipment operates stably while facilitating the picking up and putting down of materials and disassembly and maintenance.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0023] Example 1: Reference Figures 1-5 This invention proposes a high-efficiency planetary ball mill with easy-to-replace transmission components, including a housing 1. The housing 1 is equipped with switches, an operation panel, and conventional function keys similar to those in the prior art. The overall structure of the housing 1 is as follows: Figures 1-4 As shown, the system includes a horizontal frame 11 and a vertical frame 12. The vertical frame 12 is fixedly connected to the top of the horizontal frame 11, and the length of the vertical frame 12 is approximately half the length of the horizontal frame 11. The vertical frame 12 serves as the working area of ​​the ball mill, and the horizontal frame 11 serves as the feeding area. The casing 1 is equipped with: a tilting mechanism 2, a planetary gear system 3, multiple ball mill jar mechanisms 4, and a power mechanism 5, wherein: The flipping mechanism 2 is rotatably connected to the lower part of the vertical frame 12. The flipping mechanism 2 includes a hinge 21, a support plate 22, a positioning block 23, and a baffle 24. The hinge 21 hinges one side of the support plate 22 to the lower edge of the vertical frame 12, so that the support plate 22 can rotate between 0° and 90°. The positioning block 23 is fixedly connected to the side of the support plate 22 opposite to the hinge 21. The positioning block 23 is a right triangle and can play a stabilizing support role when the support plate 22 rotates to the vertical direction. A baffle 24 is provided at the upper edge of the vertical frame 12. When the support plate 22 rotates to 90°, the baffle 24 is inserted into the fixing bolts at both ends to restrict the support plate 22 and prevent it from turning over. The planetary gear train mechanism 3 includes a revolution part and a rotation part. The revolution part and the rotation part mesh with each other and are both mounted on the support plate 22. The rotation ratio of the revolution part to the rotation part is 1:2, that is, for every one revolution, the rotation part rotates twice. Multiple grinding jar mechanisms 4 are located above the planetary gear system 3, and all multiple grinding jar mechanisms 4 are connected to the rotating part and rotate together with the rotating part. When the support plate 22 is placed horizontally, it is convenient to open the multiple grinding jar mechanisms 4 to pick up and put in materials. When the support plate 22 is placed vertically, the multiple grinding jar mechanisms 4 rotate in a horizontal state, which helps the materials in the jar to achieve a more thorough grinding effect. The power mechanism 5 is located below the multiple ball mill jar mechanisms 4 and provides power to the planetary gear train mechanism 3, such as... Figure 5 As shown, the power mechanism 5 includes a motor 51 and a transition structure 52. The motor 51 is fixedly connected to the bottom of the support plate 22. The output shaft of the motor 51 is connected to one end of the transition structure 52, and the other end of the transition structure 52 is fixedly connected to the planetary gear mechanism 3 through a coupling.

[0024] Example 2: To facilitate the installation, disassembly, and maintenance of the planetary gear train mechanism 3, further improvements are made to the planetary gear train mechanism 3 based on the above embodiment 1, as follows: like Figures 6-10 As shown, a circular fixing plate 37 and a circular fixing plate 38 are installed at the center of the support plate 22. The fixing plate 38 is located at the center of the fixing plate 37. The fixing plate 37 is fixedly connected to the bottom of the support plate 22 by several mounting plates, and the fixing plate 38 is connected to the fixing plate 37 as a whole by the mounting plates. The fixing plate 37 and the fixing plate 38 are used together to connect and support the planetary gear train mechanism 3. Specifically, in the planetary gear train mechanism 3, the revolution part is the sun gear 31, which is located on the top of the fixing plate 38. The rotation part is a plurality of planet gears 32, which are evenly distributed on the outer periphery of the sun gear 31 and mesh with the sun gear 31, so as to realize the purpose of the plurality of planet gears 32 rotating with the rotation of the sun gear 31.

[0025] Furthermore, the planetary gear train mechanism 3 also includes a gear ring fixing part, which limits the movement of multiple planet gears 32. The gear ring fixing part includes several gear rings 33 (e.g., Figure 10 Several gear rings 33 are assembled into a circle, and each gear ring 33 meshes with multiple planetary gears 32, allowing the planetary gears 32 to rotate by engaging with the inner teeth of the gear rings 33. In this embodiment, three gear rings 33 are set equally, and each gear ring 33 is positioned by a spring positioning block 34 (e.g., Figure 9The fixed plate 37 is detachably connected to the top of the fixed plate 37, specifically: three snap-fit ​​blocks 371 are fixedly connected to the top of the fixed plate 37, and each toothed ring 33 has a through-hole 331 in the middle, the shape of which is set as follows: Figure 10 As shown, insertion holes 332 are also provided on both sides of the mating hole 331. The snap-fit ​​block 371 is adapted to the mating hole 331. Each gear ring 33 is fitted onto the snap-fit ​​block 371 and rotated so that the mating hole 331 and the snap-fit ​​block 371 fit tightly. The spring positioning block 34 is inserted into the mating hole 331 and cooperates with the snap-fit ​​block 371. The spring positioning block 34 is connected to the spring positioning bead. The spring positioning bead includes a spring 341 and steel balls 342 fixedly installed at both ends of the spring 341. When the spring positioning block 34 cooperates with the snap-fit ​​block 371, the spring 341 pushes the steel balls 342 at both ends of its ends into the insertion hole 332, which plays the role of fixing the spring positioning block 34. At this time, the spring positioning block 34 cooperates with the snap-fit ​​block 371 to detachably connect the gear ring 33 to the top of the fixed plate 37. If a part of the gear ring 33 or the planetary gear 32 needs to be repaired, only the gear ring 33 needs to be removed and some parts replaced, which facilitates quick disassembly, repair or replacement.

[0026] like Figures 6-8 As shown, the planetary gear train mechanism 3 also includes a pressure plate 35, a lever, and a central drive rod 36. The lever is located at the center of the sun gear 31, and the pressure plate 35 presses the lever to lock the central drive rod 36. Specifically, a mounting hole is formed at the center of the sun gear 31. In this embodiment, the mounting hole is a regular hexagon, and cross-shaped grooves 311 are formed at intervals around the outer periphery of the mounting hole (e.g., ...). Figures 7-8 The cross-shaped groove 311 is used to arrange the levers. There are three sets of levers. Each set of levers includes a lever 39 and a second spring 30. The bottom of the second spring 30 is fixedly installed inside the cross-shaped groove 311. The lever 39 is fixedly connected to the top of the second spring 30. The central drive rod 36 has a limiting groove at the corresponding position of each lever 39. One end of the lever 39 is located inside the cross-shaped groove 311 and its end extends to the outside of the cross-shaped groove 311. The other end of the lever 39 is located inside the limiting groove. The pressure plate 35 is fixedly connected to the top of the sun gear 31 by bolts. When the pressure plate 35 is installed, it presses the end of each lever 39 located in the cross-shaped groove 311, thereby causing the end of the lever 39 located in the limiting groove to lift up and cooperate with the central drive rod 36 to lock the central drive rod 36. The structure in which the levers and the central drive rod 36 are locked together can use a larger clearance fit, which is more conducive to the disassembly and maintenance of parts.

[0027] Example 3: Based on the above embodiments 1 and 2, in order to facilitate the sealing connection of the ball mill jar mechanism 4 and make it easy to disassemble, the following further improved design is made to the ball mill jar mechanism 4.

[0028] like Figures 11-16 As shown, the grinding jar mechanism 4 is generally arranged on the planetary gear train mechanism 3. In this embodiment, the grinding jar mechanism 4 includes six grinding jars. Each grinding jar mechanism includes a fixed base 41 and a jar body. The bottom of the fixed base 41 is fixedly connected to the corresponding planetary gear 32. A fastening member 42 is provided between the jar body and the fixed base 41, and the jar body is detachably connected to the fixed base 41 by the fastening member 42; specifically: refer to Figures 12-13 The fastener 42 includes a chuck 421 and multiple latches 422. The chuck 421 surrounds the outer periphery of the tank body. Several connecting rods 4211 are connected to the bottom of the chuck 421. A cylindrical hole is provided on the fixing base 41 corresponding to each connecting rod 4211. When the chuck 421 is pressed, the connecting rod 4211 can be inserted into the cylindrical hole and moved downward. The multiple latches 422 are correspondingly arranged with the multiple connecting rods 4211. In this embodiment, three latches 422 and three connecting rods 4211 are evenly distributed. A groove 43 is opened around the tank body corresponding to the multiple latches 422. The multiple latches 422 penetrate the outer shell of the fixing base 41 and are engaged in the groove 43. The cooperation structure between each latch 422 and each connecting rod 4211 is as follows. Figure 13 As shown, the bottom of the connecting rod 4211 is inclined, and three through holes are opened on the fixing base 41. Each latch 422 is fixedly connected in the through hole by a threaded structure. One end of the latch 422 adopts a conical structure, and a spring 423 is provided in the middle of the latch 422. When the connecting rod 4211 moves downward and contacts the conical surface of the latch 422, it continues to press the chuck 421 downward. The inclined surface of the connecting rod 4211 presses the conical surface of the latch 422, causing the inner end of the latch 422 to move outward and disengage from the slot, thereby facilitating the removal of the can body.

[0029] Furthermore, the can body includes a can body 44, a can lid 45, and a turntable 46. The bottom of the can body 44 has a protrusion that engages with a groove in the fixing seat 41, allowing the can body 44 to be stably installed within the fixing seat 41. The can lid 45 is installed on top of the can body 44, and the turntable 46 is connected to the can lid 45. The turntable 46 rotates the can lid 45, thereby opening or closing the can body 44. Specifically, the turntable 46 includes a handle 461, a connecting plate 462, and a transmission rod 463, such as... Figures 14-15As shown, the handle 461 is fixedly installed at the top center of the connecting plate 462, and the transmission rod 463 is fixedly installed at the bottom of the connecting plate 462. In this embodiment, there are three transmission rods 463. The transmission rod 463 is L-shaped, including a vertical section and a horizontal section. The end of the horizontal section of the transmission rod 463 is connected to the positioning rod 464. Part of the vertical section of the transmission rod 463 and part of the positioning rod are inserted into the fitting 451 at the bottom of the can lid 45 to form an integral part with the can lid 45. The horizontal section of the transmission rod 463 is located at the bottom of the fitting. Three connecting ears 441 are circumferentially arranged at the upper opening of the can body 44. The position and shape of the connecting ears 441 are adapted to the fitting 451. The bottom of part 1 has a positioning hole. When the handle 461 is pressed and the connecting plate 462 is rotated, the transmission rod 463 moves downward in the accessory, so that the upper end of the positioning rod 464 is flush with the bottom of the connecting ear 441. At this time, the can lid 45 will rotate simultaneously with the connecting plate 462. After the positioning rod 464 rotates to match the positioning hole, the handle 461 is released and no force is applied. The upper end of the positioning rod 464 is locked in the positioning hole, thus achieving the purpose of sealing and locking the can lid 45 and the can body 44. When it is necessary to open the can lid 45, the handle 461 is pressed again to disengage the upper end of the positioning rod 464 from the positioning hole, and then the connecting plate 462 is rotated in the opposite direction to separate the can lid 45 from the can body 44.

[0030] Example 4: The present invention provides a high-efficiency planetary ball mill with easy-to-replace transmission components. During use: First, place the tilting mechanism 2 horizontally so that the multiple ball milling jar mechanisms 4 are in a vertical state. At this time, the jar cover 45 can be opened through the turntable 46, and materials and ball milling media (steel balls, etc.) can be added into the jar body 44. Then, tighten the jar cover through the turntable 46. Next, rotate the flipping mechanism 2 from a horizontal state to a vertical state, and use the baffle 24 and the fixing bolt to clamp the support plate 22, so that the flipping mechanism 2 is fixed in the vertical position; Then, the motor 51 is started. The motor 51 drives the central drive rod 36 to rotate through the adapter structure 52. The central drive rod 36 drives the sun gear 31 connected to it to rotate. At the same time, the planet gear 32 that is circumferentially matched with the sun gear 31 rotates on its own axis, thereby fully grinding the material in each ball mill jar. Finally, after the ball milling is complete, turn the tilting mechanism 2 to a horizontal position, remove the ball mill jar, and open the jar lid 45 to process the fully ground material.
