Description

Technical Field

[0001] The invention relates to the technical field of mixers, and in particular to a planetary transverse support mechanism capable of adjusting the speed ratio of the planetary axis and a mixer using the mechanism. Background Art

[0002] The existing mixers on the market mainly use the motor to drive the horizontal support to revolve, and the gear transmission to drive the rotating cup to rotate, so as to achieve material mixing. The existing horizontal support structure has two types: fixed rotational speed ratio and adjustable rotational speed ratio.

[0003] The prior art proposes a cross support that can adjust the speed ratio of the main shaft, as shown in the accompanying drawings of the specification. Figure 4 As shown, the transverse support is provided with a rotation center gear 24, a transition spur gear 25, a transition bevel gear 26, a lower bevel gear 27 of a rotating cup, a revolution drive wheel 28 and a rotation drive wheel 29. The transverse support is driven to revolve by a revolution motor, and the rotation motor drives the rotation center gear 24 coaxial with the revolution, and the gear drives the lower bevel gear 27 of the rotating cup to rotate through the transition spur gear 25 and the transition bevel gear 26, thereby realizing the rotation of the rotating cup.

[0004] The existing transverse support structure can realize the revolution and cup self-rotation at different speeds by adjusting the speed of the revolution motor and the self-rotation motor. Among them, the revolution speed is marked as n1', the torque is marked as T1'; the self-rotation speed is marked as n2', the torque is marked as T2'; the relative speed of the cup is marked as n4', the torque is marked as T4'; the transmission speed ratio coefficient from the central gear to the cup is k', and the value of k' is in a certain proportional relationship with the number of teeth of the self-rotating central gear 24, the transition spur gear 25, the transition bevel gear 26, and the lower bevel gear 27 of the cup, then the relationship between the various speeds satisfies the relationship: n4' / n1'=k'*(n2' / n1'-1), and the relationship between the various torques satisfies the relationship: T4'=-T1' / k'=T2' / k'. According to the number of gear teeth, k'=0.5 can be determined.

[0005] When n2′ / n1′=-1~0, that is, the revolution motor and the self-rotation motor rotate in opposite directions at a certain speed ratio, it can be seen from the torque relationship that the torque directions of T1 and T2 are always opposite. That is, both the revolution motor and the self-rotation motor maintain positive output. At this time, n4′ / n1′=-1~-0.5, that is, the revolution motor and the self-rotation motor rotate in opposite directions at this speed ratio, and the system can maintain stable operation.

[0006] When n2′ / n1′=0~1, that is, the revolution motor and the self-rotation motor rotate in the same direction at a certain speed ratio, it can be seen from the torque relationship that the torque directions of T1′ and T2′ are always opposite. That is, one of the revolution motors or the self-rotation motors must output reverse torque (technically impossible). In actual operation, one motor will stall or cause a drag alarm, causing the system to be unable to operate stably. That is, the revolution and rotor speed ratio n4′ / n1′=-0.5~0 calculated by the formula cannot be achieved.

[0007] From the above analysis, it can be seen that the existing cross support structure with adjustable speed ratio can only achieve speed ratio adjustment in the range of 1 to 0.5, and speed ratio adjustment in the range of 0.5 to 0 cannot be achieved. Among them, 0.5 is the critical point of speed regulation. When the speed of the self-rotating motor is 0, that is, n2′ / n1′=0, the speed regulation critical point appears. The speed regulation critical point n4′ / n1′=-k′, the speed regulation critical point value of the equipment can be changed by adjusting the number of teeth of the transmission gear. However, no matter how the number of teeth of the transmission gear is adjusted, the k′ value can never be equal to 0. That is, the speed regulation critical point always exists, and the speed mode with a speed ratio of 0 cannot be achieved. That is, the equipment cannot work in the area with a speed ratio range of -k′~0, and there is a speed regulation blind spot.

[0008] In summary, although the existing cross support structure can adjust the speed ratio of the public and the automatic transmission, the speed ratio adjustment range achieved by this structure is very narrow, and the speed ratio adjustment of the full speed section cannot be achieved, and there is a blind spot in speed regulation. At the same time, the transmission structure also adopts belts, round belts, synchronous belts and other structural forms, but these transmissions have a common feature, that is, although the public and automatic transmission ratio can be adjusted, there is a blind spot in the speed ratio adjustment range.

[0009] The rotation speed is a key factor in determining the temperature rise of the material. Since the rotation speed cannot be adjusted in a wider range, the temperature rise of the material cannot be well controlled. This characteristic also determines that the current mixer can only be used for mixing some materials, and the scope of application is small. Different rotation speed ratios are required for materials with different viscosities. Due to the blind spot of speed regulation, it will not be applicable to the mixing of materials within a specific viscosity range, and the scope of application of the equipment is reduced. Summary of the invention

[0010] In view of the above, it is necessary to provide a planetary cross support mechanism with adjustable speed ratio and a mixer using the mechanism, so as to solve the problem that the existing mixer cannot adjust the speed ratio in all speed sections due to the existence of a speed regulation blind spot.

The revolving shaft is connected to the output shaft of the revolving motor and is driven to rotate by the revolving motor; the coaxial movable sleeve of the ring gear structure is arranged on the outer side of the central gear, and is connected to the output shaft of the revolving motor through a self-rotating drive component, and the ring gear structure is driven to rotate by the self-rotating motor; the inner side of the ring gear structure is meshingly connected with a planetary gear, and is meshingly connected to the central gear through the planetary gear, and the planetary gear is rotatably installed on the bevel gear integrated planetary carrier; the bevel gear integrated planetary carrier is coaxially movable sleeved on the outer side of the revolving shaft, and there is a gap between it and the central gear and the ring gear structure, and the bevel gear integrated planetary carrier is connected to the rotor shaft through a rotor drive component, and one end of the rotor shaft rotates through the cross support and is connected to the rotor.

[0014] Preferably, the rotor drive assembly is a bevel gear assembly, a belt assembly or a spur gear assembly.

[0015] Preferably, the self-rotating drive assembly is a bevel gear assembly, a belt assembly or a spur gear assembly.

[0016] Preferably, the output shaft of the revolving motor is drivingly connected to the revolving shaft via a revolving drive assembly, and the revolving drive assembly is a coupling, a bevel gear assembly, a belt assembly or a spur gear assembly.

[0017] Preferably, the rotor cup and the gear ring structure are arranged on opposite sides of the transverse support.

[0018] Preferably, at least two planetary gears are provided, and all the planetary gears are spaced around the circumference of the central gear and are installed on the same bevel gear integrated planetary carrier.

[0019] Preferably, at least two rotating cups are spaced apart on the transverse support, and all rotating cups are evenly arranged around the circumference of the revolution axis.

[0020] Preferably, the rotor shaft is tilted, and one end thereof connected to the rotor shaft is closer to the axis of the revolution shaft than the other end.

[0021] The present invention also provides a mixer, which comprises the planetary cross support mechanism as described above.

[0022] Preferably, the mixer further comprises an outer shell, the interior of the outer shell is hollow to form a storage cavity, and a bracket for mounting the planetary cross support mechanism is arranged in the storage cavity.

[0023] Preferably, a loading port is provided at the top of the shell, and a loading safety door is provided for covering the loading port; an operation screen, an emergency stop button, and a start switch are also provided at the top of the shell, and an electric control system is provided inside the shell, and the operation screen, the emergency stop button, the start switch, the revolving motor, and the rotating motor are all electrically connected to the electric control system.

[0024] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0025] 1. The present invention uses a dual-motor driven planetary gear structure to adjust the speed ratio. During operation, the self-rotating motor inputs power from the ring gear structure, and after the planetary gears are meshed and driven, the power is transmitted to the rotor through the bevel gear integrated planetary carrier. The revolving motor inputs power from the center gear, and after the planetary gears are meshed and driven, the power is transmitted to the rotor through the bevel gear integrated planetary carrier. The bevel gear integrated planetary carrier and the planetary gears receive the power input from the ring gear structure and the center gear, and after motion synthesis, transmit it to the rotor. The present invention adopts the above-mentioned planetary gear structure, with the ring gear structure as the power input terminal one, the center gear as the power input terminal two, and the bevel gear integrated planetary carrier as the power output terminal to transmit power to the rotor, thereby realizing a wide range of adjustment of the full-speed section of the public-self speed ratio.

[0026] 2. The present invention can adjust the speed ratio by adjusting the speed of the two motors. During the entire speed regulation process, the output directions of the two motors are always the same as the torque output direction, and the motors always maintain positive output. The revolving motor or the rotating motor will not stall or drag alarm, thereby ensuring the stability of the system.

[0027] 3. The present invention can not only realize the high revolution and low rotation operation mode with a revolution speed ratio of 0 to 0.5, but also realize the low revolution and high rotation operation mode with a revolution speed ratio of 1.5 to 2. The two modes are respectively suitable for special material mixing requirements, and the equipment can be used in special material industries. The present invention can realize the speed ratio range adjustment from 0, expand the adjustment range of the revolution speed ratio, and for materials with different viscosities, the applicable revolution speed ratio is different, so the present invention can be applied to a wider range of materials.

[0028] 4. The present invention can realize a speed mode in which the rotor rotates at a constant speed and the revolution speed is continuously increased or decreased. This stirring mode cannot be realized by the original horizontal support structure with adjustable speed ratio. For material degassing, a suitable rotor speed is selected. The speed is determined in principle to ensure that the material does not centrifugally stratify and the temperature does not rise significantly. While keeping the rotor speed unchanged, the revolution speed can be increased to increase the centrifugal acceleration, which is more conducive to the centrifugal degassing of the material.

[0029] 5. The revolving motor and the rotating motor of the present invention drive the rotating cup to rotate through motion synthesis. During the mixing and stirring process, the speed at which the material temperature rises is proportional to the rotating speed of the rotating cup. Under the same revolving speed, the present invention can achieve a lower rotating cup speed, thereby more effectively controlling the temperature rise of the material.

[0039] Example 1

[0040] like Figure 1 As shown, a planetary transverse support mechanism with adjustable speed ratio includes a transverse support 1, a rotor cup 2, a central gear 6, a ring gear structure 7, a bevel gear integrated planetary carrier 9, a planetary gear 8, a revolving motor 10 and a rotating motor 12.

[0041] The horizontal support 1 is fixedly inserted with a revolution shaft 5, and the outer fixed sleeve of the revolution shaft 5 is provided with a central gear 6. The revolution shaft 5 is connected to the output shaft of the revolution motor 10 and is driven to rotate by the revolution motor 10. The central gear 6 and the horizontal support 1 are both fixedly connected to the revolution shaft 5 and rotate together with the revolution shaft 5.

[0042] Among them, the output shaft of the revolving motor 10 is connected to the revolving shaft 5 through a revolving drive assembly, and the revolving drive assembly is a coupling, a bevel gear assembly, a belt assembly or a spur gear assembly. In this embodiment, the revolving drive assembly is a belt assembly, and the revolving motor 10 is belt-driven through a revolving pulley sleeved on the output shaft, a revolving pulley sleeved on the revolving shaft 5, and a revolving belt 11 on the two revolving pulleys, and finally drives the central gear 6 and the cross support 1 to rotate together. The way in which the revolving motor 10 drives the central gear 6 and the cross support 1 is not limited to belt connection transmission, and transmission methods that achieve the same effect, such as direct connection, spur gears, bevel gears, etc., all belong to similar structures.

[0043] The gear ring structure 7 is coaxially movably sleeved on the outside of the central gear 6, and the gear ring structure 7 is connected to the output shaft 14 of the self-rotating motor through a self-rotating drive assembly, and the gear ring structure 7 is driven to rotate by the self-rotating motor 12. Wherein, the self-rotating drive assembly is a bevel gear assembly, a belt assembly or a spur gear assembly. In the present embodiment, the self-rotating drive assembly is a spur gear assembly, including a transmission spur gear 13, which is sleeved on the output shaft 14 of the self-rotating motor, and is meshed with the outer toothed structure of the gear ring structure 7. The self-rotating motor 12 is meshed and connected with the toothed structure on the outer side of the gear ring structure 7 through the transmission spur gear 13 sleeved on the output shaft, and finally drives the gear ring structure 7 to rotate. The way in which the self-rotating motor 12 drives the gear ring structure 7 is not limited to the spur gear connection, and the transmission methods such as belts and bevel gears that achieve the same effect all belong to similar structures.

[0044] In this embodiment, the inner and outer sides of the ring gear structure 7 are provided with tooth structures. The inner side of the ring gear structure 7 is meshed with a planetary gear 8, and the planetary gear 8 is meshed with the central gear 6. The planetary gear 8 is rotatably mounted on the bevel gear integrated planet carrier 9. Specifically, the rotating shaft of the planetary gear 8 is mounted on the bevel gear integrated planet carrier 9. The number of planetary gears 8 can be one or more. When multiple planetary gears 8 are provided, the structure is more stable. At this time, all planetary gears 8 are spaced around the circumference of the central gear 6 and are installed on the same bevel gear integrated planet carrier 9. In this embodiment, four planetary gears 8 are provided, which has good stability. The bevel gear integrated planet carrier 9 is transmission-connected with the central gear 6 and the ring gear structure 7 through the planetary gear 8. The bevel gear integrated planet carrier 9 is coaxially movably sleeved on the outer side of the revolution shaft 5, and there is a gap between it and the central gear 6 and the ring gear structure 7. Specifically, the bevel gear integrated planet carrier 9 is movably sleeved on the outer side of the revolution shaft 5 through a bearing, and the structure is more stable. The bevel gear integrated planet carrier 9 is coaxial with the revolution shaft 5 and can rotate independently with the cross support 1.

[0045] The planetary carrier 9 with integrated bevel gears is connected to the rotor shaft 3 through the transmission of the rotor drive assembly, and one end of the rotor shaft 3 rotates through the horizontal support 1 and then connects to the rotor 2. Among them, the rotor drive assembly is a bevel gear assembly, a belt assembly or a spur gear assembly. In this embodiment, the rotor drive assembly is a bevel gear assembly, including a transmission bevel gear 4, which is fixedly sleeved on one end of the rotor shaft 3. The outer side of the planetary carrier 9 with integrated bevel gears is provided with a bevel gear structure, and the transmission bevel gear 4 is meshed and connected through the bevel gear structure. The way in which the rotor drive assembly drives the rotor shaft 3 is not limited to the spur gear connection, and the transmission methods such as belts and bevel gears that achieve the same effect all belong to similar structures.

[0046] Among them, the rotor cup 2 and the gear ring structure 7 are arranged on opposite sides of the horizontal support 1, and the rotor cup shaft 3 can be set vertically or tilted. When it is tilted, one end connected to the rotor cup 2 is closer to the axis of the revolution shaft 5 than the other end. The number of rotor cups on the horizontal support 1 is not limited, but in the specific implementation, two rotor cups 2 are a better choice. When the number of rotor cups set is greater than 1, all rotor cups 2 are evenly surrounded by the circumference of the revolution shaft 5. This embodiment is provided with two rotor cups 2, which are symmetrically arranged on the left and right, and have good stability when rotating. The bevel gear integrated planetary carrier 9 transmits power to the rotor cup 2 through the transmission bevel gear 4.

[0047] In the present invention, the transverse support 1 and the central gear 6 are installed on the revolving shaft 5 and driven to rotate by the revolving motor 10. The rotating cup 2 is installed coaxially with the transmission bevel gear 4, the bevel gear integrated planetary carrier 9 drives the rotating cup 2 to rotate through the transmission bevel gear 4, and the ring gear structure 7 is driven to rotate by the self-rotating motor 12. When the revolving motor 10 rotates, it drives the central gear 6 and the transverse support 1 to rotate, and when the self-rotating motor 12 rotates, it drives the ring gear structure 7 to rotate. The central gear 6 and the ring gear structure 7 drive the bevel gear integrated planetary carrier 9 to rotate through the planetary gear 8, and the bevel gear integrated planetary carrier 9 drives the transmission bevel gear 4 and the rotating cup 2 to rotate, that is, the revolving motor 10 and the self-rotating motor 12 drive the rotating cup 2 to rotate by themselves through motion synthesis. The two powers input by the central gear 6 and the ring gear structure 7 are output to the rotating cup 2 through the meshing transmission of the planetary gear 8 and the bevel gear integrated planetary carrier 9.

[0048] Through the above arrangement, when the present invention is working, the self-rotating motor 12 inputs power from the ring gear structure 7, and after the planetary gear 8 is meshed and driven, the power is transmitted to the rotor cup 2 through the bevel gear integrated planetary carrier 9. The revolving motor 10 inputs power from the central gear 6, and after the planetary gear 8 is meshed and driven, the power is transmitted to the rotor cup 2 through the bevel gear integrated planetary carrier 9. The bevel gear integrated planetary carrier 9 and the planetary gear 8 receive the power input from the ring gear structure 7 and the central gear 6, and transmit it to the rotor cup 2 after motion synthesis.

[0049] The present invention adopts the above-mentioned planetary gear structure, with the ring gear structure 7 as the power input terminal 1, the central gear 6 as the power input terminal 2, and the bevel gear integrated planetary carrier 9 as the power output terminal to transmit power to the rotor 2, thereby realizing a wide range of adjustment in the full speed range of the speed ratio.

[0050] The specific working principle is: the revolution speed is equal to the speed of the central gear 6, and the cup speed is equal to the speed of the transmission bevel gear 4. The speed of the central gear 6 is n1, the torque is T1, and the number of teeth is Z1; the speed of the ring gear structure 7 is n2, the torque is T2, and the number of teeth is Z2; the speed of the bevel gear integrated planetary carrier 9 is n3, the torque is T3, and the number of teeth is Z3; the relative speed of the transmission bevel gear 4 is n4, the torque is T4, and the number of teeth is Z4; each speed satisfies the relationship of n4 / n1=-k*α*(n2 / n1-1) / (1+α), and each torque satisfies the relationship of T4=-(1+α)T1 / k=-(1+α)T2 / (k*α), the coefficient α=Z2 / Z1, and the coefficient k=Z3 / Z4.

[0051] The present invention can determine the speed ratio coefficient α=2, k=2 according to the structure. When n2 / n1=1~2.5, that is, the orbital and self-rotating motors rotate in the same direction at a certain speed ratio, it can be seen from the torque relationship that the torque directions of T1 and T2 are always the same. That is, both the orbital motor 10 and the self-rotating motor 12 maintain positive output. At this time, n4 / n1=0~-2, that is, the orbital and rotating cups 2 rotate in opposite directions at this speed ratio, and the system can maintain stable operation. Therefore, the speed ratio of the orbital and rotating cups 2 (n4 / n1) can achieve a speed ratio adjustment of 0~2, that is, the speed ratio can be adjusted from 0. The present invention can achieve a wide range of adjustment of the orbital and self-rotating speed ratio in the full speed range by controlling the speed of the orbital motor 12 and the speed of the self-rotating motor 10.

[0052] The present invention can achieve speed ratio adjustment by adjusting the speeds of the two motors. During the entire speed adjustment process, the output directions of the two motors are always the same as the torque output direction, and the motors always maintain positive output. The revolving motor 10 or the rotating motor 12 will not stall or cause a drag alarm, thereby ensuring the stability of the system.

[0053] The present invention can not only realize the operation mode of high revolution and low rotation with a revolution speed ratio of 0 to 0.5, but also realize the operation mode of low revolution and high rotation with a revolution speed ratio of 1.5 to 2. The two modes are respectively suitable for special material mixing requirements, and the equipment can be used in special material industries. The present invention can realize the adjustment of the speed ratio range from 0, expand the adjustment range of the revolution speed ratio, and for materials with different viscosities, different revolution speed ratios are applicable, so the present invention can be applied to a wider range of materials.

[0054] like Figure 2 As shown, the present invention also provides a mixer, which includes a housing 15 and Figure 1 The planetary cross support mechanism in.

[0055] The housing 15 is hollow inside, forming a storage chamber, and a bracket 16 for mounting the planetary transverse support mechanism is arranged in the storage chamber. Specifically, the bracket 16 includes a frame body 17 and a support plate 18 arranged on the top of the frame body 17, the support plate 18 is arranged horizontally, the revolution shaft 5 of the planetary transverse support mechanism is rotatably mounted on the support plate 18, the revolution motor 10 and the rotation motor 12 are both fixedly mounted on the frame body 17 and located below the support plate 18, and the output shaft 14 of the rotation motor 12 movably passes through the support plate 18 and is connected to the transmission spur gear 13.

[0056] In addition, a loading port is provided at the top of the housing 15, and a loading safety door 19 for covering the loading port is provided to facilitate loading. An operation screen 20, an emergency stop button 21, and a start switch 22 are also provided at the top of the housing 15. An electric control system is provided in the housing 15, and the operation screen 20, the emergency stop button 21, the start switch 22, the revolution motor 10, and the rotation motor 12 are all electrically connected to the electric control system. When the start switch 22 is pressed, the horizontal support 1 operates at the set speed, and when the emergency stop button 21 is pressed, the whole machine will stop operating. The revolution speed and the revolution speed ratio of the horizontal support 1 can be set by the operation screen 20 and the electric control system. After pressing the start switch 22, the electric control system drives the revolution motor 10, the rotation motor 12, and the horizontal support 1 to rotate according to the set parameters. The present invention can also set different revolution speed ratios in sections within a working cycle through a multi-section control method, and can realize continuous switching of working speeds in sections with several different speed ratios. Casters 23 with brake function are arranged at the four corners of the bottom of the housing 15, and the casters 23 play a supporting and moving role.

[0057] The present invention can realize a speed mode in which the rotating cup 2 rotates at a constant speed and the revolution speed is continuously increased or decreased. This stirring mode cannot be realized by the original horizontal support structure with adjustable speed ratio. For material degassing, a suitable rotating cup 2 speed is selected. The speed is determined in principle to ensure that the material does not centrifugally stratify and the temperature does not rise significantly. While keeping the rotating cup 2 speed unchanged, the revolution speed can be increased to increase the centrifugal acceleration, which is more conducive to the centrifugal degassing of the material.

[0058] The revolving motor 10 and the rotating motor 12 of the present invention drive the rotating cup 2 to rotate through motion synthesis. During the mixing and stirring process, the speed at which the material temperature rises is proportional to the rotation speed of the rotating cup 2. Under the same revolving speed, the present invention can achieve a lower rotating speed of the rotating cup 2, so the temperature rise of the material can be more effectively controlled.

[0059] Example 2

[0060] In this embodiment, the self-rotation drive assembly of the planetary lateral support mechanism includes a transmission spur gear 13, a transmission shaft 31, two self-rotation pulleys and a self-rotation belt 30. The two self-rotation pulleys are respectively mounted on one end of the transmission shaft 31 and the output shaft of the self-rotation motor 12, the self-rotation belt 30 is mounted on the two self-rotation pulleys, and the transmission spur gear 13 is mounted on the end of the transmission shaft 31 away from the self-rotation pulley and is meshed with the ring gear structure 7.

[0061] The gear ring structure 7 includes an upper gear ring and a lower gear ring connected to each other, the upper gear ring and the lower gear ring are coaxial and integrally arranged, the inner side of the upper gear ring and the outer side of the lower gear ring are both provided with toothed structures, the toothed structure on the inner side of the upper gear ring is meshed and connected with the planetary gear 8, and the toothed structure on the outer side of the lower gear ring is meshed and connected with the transmission spur gear 13.
