Description

Technical Field

[0001] This utility model relates to the field of planetary structure technology, specifically to a three-input planetary structure with independent control of its revolution and rotation. Background Technology

[0002] In industries such as coatings, adhesives, lithium battery pastes, and food blending, material mixing and dispersion are critical processes. Due to the complex properties of the materials, both strong high-speed dispersion to break up agglomerates and stable low-speed mixing to drive the overall tumbling and circulation of the materials are required. Therefore, actual working conditions often require the superposition of both "rotation" and "revolution" motions. However, most common equipment can only achieve limited motion combinations through a single motor and fixed mechanical structure. Rotation and revolution are often bound together, and the speed cannot be independently controlled, making it difficult to achieve uniformity, dispersion efficiency, and mixing stability under different working conditions.

[0003] Existing planetary mixing structures typically rely on a planetary carrier to drive the mixing paddle to revolve around the sun, and then achieve rotation through internal gears. However, most of them use a single power source with separate power outputs. Although this structure can achieve a mixed motion of revolution and rotation, since all power is output from the same motor, the speed coupling is obvious and cannot be flexibly adjusted. For example, when users want to improve the high-speed dispersion cutting effect, the speed of the low-speed mixing shaft will also be passively changed, making it difficult to make precise control for different materials. In addition, in order to arrange multiple drive shafts, traditional planetary structures usually require multiple intermediate shafts and support structures, which occupy a lot of space, have long transmission chains, and are difficult to maintain. Moreover, the more shafts there are, the more likely there will be problems such as eccentricity, wear and vibration.

[0004] As process requirements continue to increase, the industry needs a structure that can simultaneously satisfy high-speed dispersion, low-speed mixing, and planetary motion, and the rotation speed and direction of these three components can be adjusted completely independently to flexibly adapt to the rheological properties of different materials. For example, in high-viscosity materials, it is necessary to enhance the planetary revolution to drive the overall flow; when it is necessary to refine the particles, it is necessary to increase the dispersion rotation speed; and when it is not desirable to generate excessive shear, it is necessary to reduce the mixing rotation speed.

[0005] In view of the above, this device proposes a three-input planetary structure with independent control of revolution and rotation to solve some of the aforementioned problems; by arranging multiple drive shafts coaxially, the stirring shaft, dispersing shaft, and planetary carrier are each driven by an independent motor, which can break through the coupling limitations of traditional planetary mechanisms; at the same time, through reasonable gear, chain, and synchronous belt transmission paths, each component can maintain stable rotation while revolutionizing, forming a more efficient and controllable composite mixing motion mode, which meets the higher requirements of modern material processing for mixing and dispersion uniformity.

[0014] Optionally, the A drive device includes a driven gear, a driving gear, and a geared motor; the geared motor drives the driving gear to rotate through its output end, and the driving gear meshes with the driven gear mounted on the planetary carrier, causing the planetary carrier to revolve.

[0015] Optionally, the B drive device includes a chain, a drive sprocket, and an A motor; wherein one end of the chain meshes with the driven sprocket, the other end is connected to the drive sprocket, and the output end of the A motor is fixedly connected to the drive sprocket.

[0016] Optionally, the rotating assembly is disposed inside the planetary carrier and includes planetary gears and a sun gear; wherein the planetary gears are fixed on the low-speed stirring shaft, and the sun gear is fixed on the stirring drive shaft and meshes with the planetary gears.

[0020] This invention provides a three-input planetary structure with independent control of its revolution and rotation, which has the following advantages:

[0021] 1. This utility model provides a three-input planetary structure with independent control of revolution and rotation. By combining revolution, stirring rotation, and high-speed dispersion into a single structure, it achieves a stronger mixing effect than ordinary stirring or dispersing equipment. The planetary carrier rotates with all stirring components, allowing the material to move as a whole within the container. Simultaneously, the stirring shaft and dispersing shaft can each rotate independently, one responsible for low-speed, high-flow-rate material agitation, and the other for high-speed shearing and rapid dispersion. The combined effect of these two functions prevents material from accumulating in dead corners, resulting in more thorough circulation and a significantly improved mixing speed. Furthermore, all three drives are coaxially arranged, making the entire structure more compact and space-saving than traditional equipment. The shorter and more stable transmission chain reduces the likelihood of uneven wear or deviation. Overall, this structure offers advantages over ordinary equipment in terms of efficiency, uniformity, stability, and structural compactness. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] This application proposes a three-input planetary structure with independent control over its revolution and rotation, as detailed below:

[0027] For reference Figure 1 The geared motor 23 drives the planetary carrier 1 to rotate via drive device A 2, achieving revolution; motor A 53 drives the stirring drive shaft 3 to rotate via drive device B 5, thereby driving the low-speed stirring shaft 6 to rotate; motor B 103 drives the dispersion drive shaft 8 to rotate via drive device C 10, driving the high-speed dispersion shaft 11 to rotate. When the three work together, the low-speed stirring shaft 6 and the high-speed dispersion shaft 11 rotate as a whole along with the revolution of the planetary carrier 1, thus forming a hybrid motion structure of superimposed revolution and rotation.

[0028] For reference Figure 1 The planetary carrier 1 is equipped with an A drive device 2 on one side, which enables rotational operation. The A drive device 2 includes a driven gear 21, a driving gear 22, and a geared motor 23. The geared motor 23 drives the driving gear 22 to rotate through its output end. The driving gear 22 meshes with the driven gear 21 mounted on the planetary carrier 1, causing the planetary carrier 1 to revolve.

[0029] For reference Figure 1 The stirring drive shaft 3 is mounted at one end in the middle of the planetary carrier 1, and at the other end is a driven sprocket 4. A drive device B 5 is connected to one side of the driven sprocket 4. The drive device B 5 includes a chain 51, a drive sprocket 52, and a motor A 53. One end of the chain 51 meshes with the driven sprocket 4, and the other end is connected to the drive sprocket 52. The output end of the motor A 53 is fixedly connected to the drive sprocket 52. By driving the driven sprocket 4, the driven sprocket 4 is rotated, which in turn causes the stirring drive shaft 3 to rotate.

[0030] For reference Figure 1The low-speed stirring shaft 6 is fixedly mounted on the planetary carrier 1, and a rotating assembly 7 is provided on its side and connected to the stirring drive shaft 3. Through the rotating assembly 7, the rotational power of the stirring drive shaft 3 can be transmitted to the low-speed stirring shaft 6, thereby driving the low-speed stirring shaft 6 to achieve independent rotation. Further, the rotating assembly 7 includes a planetary gear 71 and a sun gear 72. The planetary gear 71 is fixedly sleeved on the low-speed stirring shaft 6, and the sun gear 72 is coaxially fixed on the stirring drive shaft 3 and meshes with the planetary gear 71. When the stirring drive shaft 3 rotates, the sun gear 72 drives the planetary gear 71 to roll, thereby driving the low-speed stirring shaft 6 to achieve rotation. Based on the above structure, through planetary gear transmission, the low-speed stirring shaft can maintain stable rotational motion while revolving around the planetary carrier, allowing the stirring paddle to operate on a combined trajectory of revolution and rotation, significantly improving the material circulation efficiency and mixing uniformity. At the same time, planetary gear meshing transmission has advantages such as high efficiency, uniform force distribution, and compact structure, which can improve the reliability and applicability of the entire machine.

[0031] For reference Figure 1 The dispersion drive shaft 8 is a sleeve structure, coaxially arranged inside the stirring drive shaft 3. One end of the shaft is fixedly connected to a driven V-belt pulley 9, which is driven by a C-drive device 10. After the C-drive device 10 is started, it rotates the driven V-belt pulley 9 through belt drive, thereby driving the dispersion drive shaft 8 to rotate at high speed. The high-speed dispersion shaft 11 is located on the side of the low-speed stirring shaft 6 and is fixedly mounted on the planetary carrier 1. One end of the high-speed dispersion shaft 11 is connected to a steering assembly 12, which is used to change and transmit the power of the dispersion drive shaft 8. When the dispersion drive shaft 8 rotates, the steering assembly 12 further drives the high-speed dispersion shaft 11 to rotate at high speed, thereby achieving a high-shear and high-dispersion processing effect.

[0032] Furthermore, the C drive device 10 includes a V-belt 101, a driving V-belt pulley 102, and a B motor 103. One end of the V-belt 101 is connected to the driven V-belt pulley 9, and the other end is looped around the driving V-belt pulley 102. The output shaft of the B motor 103 is fixedly connected to the driving V-belt pulley 102, so that the motor output torque is transmitted to the driven V-belt pulley 9 through the driving V-belt pulley 102 and the V-belt 101.

[0033] The steering assembly 12 includes a driving synchronous pulley 121, a synchronous belt 122, and a driven synchronous pulley 123. The driving synchronous pulley 121 is fixedly mounted at one end of the dispersion drive shaft 8. The synchronous belt 122 is meshed with both the driving synchronous pulley 121 and the driven synchronous pulley 123. The driven synchronous pulley 123 is fixedly mounted on the high-speed dispersion shaft 11. With this structure, when the dispersion drive shaft 8 rotates, its power is transmitted to the high-speed dispersion shaft 11 via the synchronous belt 122, achieving reliable linkage and steering transmission between the two.

[0034] In view of the above, the driven gear 21, the stirring drive shaft 3, the dispersing drive shaft 8, and the planetary carrier 1 are arranged coaxially, so that multiple sets of transmission structures are integrated on the same axis. This arrangement not only significantly improves the compactness of the overall structure and reduces the space occupied by the equipment, but also reduces the assembly difficulty and transmission deviation caused by the distribution of multiple shafts. Furthermore, multiple radial bearing seats, spacers, and axial limiting components are sequentially arranged on the coaxial shaft system to provide radial support and axial positioning for each shaft, ensuring concentricity and non-interference of each shaft during high-speed operation.

[0035] In this invention, the working steps of the device are as follows:

[0036] 1. Start the geared motor 23. The output torque of the geared motor 23 is transmitted to the drive gear 22. The drive gear 22 drives the driven gear 21 that meshes with it. The driven gear 21 is fixedly installed on the planetary carrier 1. Therefore, the planetary carrier 1 is driven to generate a revolution motion around the center of the equipment. As the planetary carrier 1 revolves, the stirring drive shaft 3, the low-speed stirring shaft 6, the dispersion drive shaft 8 and the high-speed dispersion shaft 11 installed on the planetary carrier all revolve as a whole.

[0037] 2. Start motor A 53, which drives the drive sprocket 52 to rotate. The drive sprocket 4 connected to it is driven to rotate through chain 51. The drive sprocket 4 is fixedly installed on the stirring drive shaft 3, so the stirring drive shaft 3 rotates. The rotation of the stirring drive shaft 3 is transmitted to the low-speed stirring shaft 6 through the rotating component 7. The rotation of the low-speed stirring shaft 6 and the revolution of the planetary carrier 1 are superimposed to generate a complex stirring trajectory, which improves the flow circulation capacity of the material and the macro-mixing efficiency.

[0038] 3. Start motor B 103, drive the active V-belt pulley 102 to rotate, and then drive the driven V-belt pulley 9 to rotate. The driven V-belt pulley 9 is fixedly connected to the dispersion drive shaft 8. Therefore, the dispersion drive shaft 8 obtains high-speed rotation power. The high-speed torque output by the dispersion drive shaft 8 is transmitted to the high-speed dispersion shaft 11 through the steering assembly 12. The high-speed dispersion shaft 11 thus achieves high-speed rotation, which is used to generate strong shear force and dispersion effect.

[0039] 4. When the above three drive systems are running simultaneously, the planetary carrier 1 continues to revolve, the low-speed stirring shaft 6 achieves rotation, and the high-speed dispersing shaft 11 achieves high-speed rotation. Both participate in material processing under the orbital trajectory, thereby forming a macroscopic material tumbling flow field of low-speed stirring + a microscopic shearing and crushing flow field of high-speed dispersing.
