[0033] Example 1

[0034] Please see Figures 1-9 This invention provides a servo motor and reducer-based electric tumble soaking machine tilting control system, comprising: a servo motor 1, a precision reducer 2, and a tilting shaft 3; the output end of the servo motor 1 is connected to the input end of the precision reducer 2, and the output end of the precision reducer 2 is connected to the tilting shaft 3; the servo motor 1 is equipped with a first encoder for real-time monitoring of the rotor position and speed of the servo motor 1, so as to cooperate with the precision reducer 2 to precisely control the tilting angle of the tilting shaft 3. The precision reducer 2 is an RV-C reducer. The first encoder is a high-precision photoelectric encoder. The input shaft and / or output shaft of the RV-C reducer are hollow shafts with cable routing channels.

[0035] The working principle and technical effects of the above technical solution are as follows:

[0036] This invention discloses an electric tumble soaking machine tilting control system based on a servo motor and a reducer. The output end of the servo motor 1 is connected to the input end of the precision reducer 2, and the output end of the precision reducer 2 is connected to the tilting shaft 3. This eliminates the large gear transmission, simplifies the structure, and reduces production costs. The servo motor is equipped with a first encoder for real-time monitoring of the servo motor rotor position and speed, which works in conjunction with the precision reducer to precisely control the tilting angle of the tilting shaft. The precision reducer 2 is an RV-C reducer, and the first encoder is a high-precision photoelectric encoder. By using the servo motor and the RV-C reducer in conjunction, the tilting angle is controlled in real time through feedback signals, improving control accuracy and reliability, and solving the problems of numerous failure points of external encoders and low system reliability. The input shaft and / or output shaft of the RV-C reducer are hollow shafts with cable routing channels, allowing cables and signal lines to be routed through the hollow shaft, avoiding the complexity and potential failures of external wiring.

[0037] Example 2

[0038] Please see Figures 1-9 The servo motor 1 and the precision reducer 2 are both mounted on the frame, which is also equipped with a support mechanism for supporting the tilting shaft 3. The support mechanism is also equipped with a protective shell structure for sealing the connection between the output end of the precision reducer 2 and the tilting shaft 3. A second encoder for real-time monitoring of the tilting angle and tilting speed of the tilting shaft 3 is installed inside the protective shell structure.

[0039] The working principle and technical effects of the above technical solution are as follows:

[0040] In the electric tumble soaking machine tilting control system based on a servo motor and a reducer of the present invention, a protective shell structure sealing cover is provided at the connection end between the output end of the precision reducer 2 and the tilting shaft 3. This effectively prevents external dust, debris, and potentially corrosive liquids from entering the connection part, avoiding wear and corrosion of the mechanical structure of the connection part caused by these impurities, thereby extending the service life of the equipment. Furthermore, the connection part between the reducer output end and the tilting shaft is in motion during equipment operation. Without protection, operators may accidentally touch these moving parts, resulting in injury. The protective shell structure can act as an isolation layer, preventing accidental contact and ensuring operator safety. The protective shell structure can also protect the connection part... It provides a certain degree of buffering and support, reducing vibration and noise generated during equipment operation, thus improving the overall stability of the equipment. It also improves the working environment and reduces the impact of noise on operators. Because the second encoder is installed inside the protective shell, the shell provides a relatively stable and clean working environment for the second encoder, preventing interference from external factors and ensuring that it can accurately monitor the flip angle and speed of the flip shaft 3 in real time. The second encoder, in conjunction with the first encoder, effectively controls the flip angle and ensures the stability and accuracy of the flipping process. The first encoder, located inside the servo motor 1, is used to monitor the rotor position and speed of the servo motor 1 in real time, working in conjunction with the precision reducer. 2. The initial control of the rotation angle of the rotating shaft 3 is performed. The second encoder is directly installed inside the protective housing structure to monitor the actual rotation angle and rotation speed of the rotating shaft 3 in real time. Through the dual monitoring of these two encoders, the rotation angle of the rotating shaft 3 can be calibrated more accurately. For example, when there is a deviation between the rotation angle calculated by the first encoder based on the motor rotor position and the actual angle of the rotating shaft 3 monitored by the second encoder, the control system can adjust the operation of the servo motor 1 in a timely manner to make the rotating shaft 3 achieve a more accurate rotation angle. In actual operation, during the transmission process from the servo motor 1 to the rotating shaft 3, manufacturing errors and wear of mechanical parts may cause deviations in angle transmission. The second encoder directly monitors the actual angle of the flipping shaft 3, compensating for these mechanical errors and further improving the control accuracy of the flipping angle. Both encoders provide real-time feedback on the status of the flipping shaft 3, allowing the control system to adjust the operating parameters of the servo motor 1 accordingly. When the flipping speed fluctuates or is subject to external interference, the control system can quickly adjust the output of the servo motor based on feedback from the first and second encoders, restoring the flipping shaft 3 to a stable operating state and ensuring the stability of the flipping process. If there is an abnormal difference in the information fed back by the two encoders, it may indicate a fault in a component of the equipment, such as a speed reducer failure or a loose transmission component. The control system can promptly issue a warning signal based on this abnormal difference and take corresponding protective measures, such as stopping the equipment to prevent further escalation of the fault and ensure the stability of the entire flipping process.

[0041] Example 3

[0042] Please see Figures 1-9 The flip shaft 3 includes: a first shaft tube 4, a shaft tube connector 5, a second shaft tube 6, and a reinforcing connector 7; the output end of the precision reducer 2 is connected to the first shaft tube 4, the second shaft tube 6 is connected to the main shaft used to carry and install materials, the first shaft tube 4 and the second shaft tube 6 are connected by the shaft tube connector 5, and the shaft tube connector 5 can control the first shaft tube 4 and the second shaft tube 6 to move closer to each other or further away from each other; the reinforcing connector 7 is slidably installed in the cable routing channel of the output shaft of the precision reducer 2, and one end of the reinforcing connector 7 is connected to the second shaft tube 6.

[0043] The working principle and technical effects of the above technical solution are as follows:

[0044] In the electric tumble soaking machine tilting control system based on a servo motor and reducer of the present invention, in order to further improve the transmission control effect of the precision reducer 2 and the tilting shaft 3, and to meet the actual needs of changing the lateral position of the tumble soaking material, the above-mentioned tilting shaft 3 structure is specially designed. The output end of the precision reducer 2 is connected to the first shaft tube 4. The first shaft tube 4 rotates under the drive of the precision reducer 2. The first shaft tube 4 and the second shaft tube 6 are connected by a shaft tube connector 5, so that the first shaft tube 4 drives the second shaft tube 6 to rotate through the shaft tube connector 5. When the second shaft tube 6 rotates, it drives the main shaft connected to it for carrying and installing materials to rotate. The middle part of the reinforcing connector 7 is slidably installed in the cable routing channel of the output shaft of the precision reducer 2, and one end is connected to the second shaft tube 6, providing additional support and constraint for the transmission between the first shaft tube 4 and the second shaft tube 6. During the transmission process, the reinforcing connector 7 can effectively prevent radial sway and axial displacement of the shaft tube, enhance the connection rigidity between the shaft tubes, and make the transmission more stable and reliable. The presence of the reinforcing connector 7 can also improve the resistance of the transmission system to external interference. For example, when the tumble soaking machine is subjected to external vibration or impact during operation, the reinforcing connector 7 can disperse these external forces throughout the transmission system, reducing the impact on the shaft tube connector 5 and the shaft tube itself, and ensuring the stability of the transmission control. The shaft tube connector 5 can control the first shaft tube 4 and the second shaft tube 6 to move closer or further apart. This allows the tumble soaking position of the material to be flexibly adjusted according to actual needs during the tumble soaking process. For example, at different production stages or for different types of tumble soaking materials, the lateral position of the material in the tumble soaking machine can be changed by adjusting the distance between the shaft tubes, so that the material can have more sufficient contact with the soaking liquid and improve the tumble soaking effect. This adjustment method can also adapt to tumble soaking materials of different specifications and sizes. For larger materials, the distance between the first shaft tube 4 and the second shaft tube 6 can be appropriately increased to provide sufficient space for the material; for smaller materials, the distance between the shaft tubes can be decreased to improve the tumbling efficiency of the material. In addition, because the transmission system is more stable and reliable, the failure rate and maintenance costs of the equipment are reduced. At the same time, by flexibly adjusting the tumble soaking position of the material, the tumble soaking effect is improved, material waste is reduced, and production costs are reduced.

[0045] Example 4

[0046] Please see Figures 1-9The shaft tube connector 5 includes: a movable flange 501 welded to the second shaft tube 6, a fixed flange 502 welded to the first shaft tube 4, and a pressure ring 503 slidably disposed on the first shaft tube 4. The fixed flange 502 is located between the movable flange 501 and the pressure ring 503. The two ends of multiple shafts 504 slidably disposed in multiple axial through holes of the fixed flange 502 are respectively connected to the movable flange 501 and the pressure ring 503. Multiple adjusting arms 505 are rotatably connected to the pressure ring 503, with the ends of the multiple adjusting arms 505 away from the pressure ring 503. It is connected to multiple adjusting seats 506; the multiple adjusting seats 506 are slidably mounted in multiple adjusting tracks on a fixed plate 507, which is fixed to the first shaft tube 4. Multiple screw rods 508 mounted in the multiple adjusting tracks are screwed into the multiple adjusting seats 506; bevel gears 509 fixed on the multiple screw rods 508 mesh with bevel gear rings 510 mounted in the annular grooves of the adjusting seats 506; multiple sockets are evenly arranged around the bevel gear ring 510, and screw posts 511 screwed onto the adjusting seats 506 are inserted into one of the sockets. The two ends of the tension spring sleeved on the first shaft tube 4 are respectively connected to the fixed flange 502 and the pressure ring 503.

[0047] The working principle and technical effects of the above technical solution are as follows:

[0048] In the electric tumble soaking machine tilting control system based on a servo motor and reducer of the present invention, when it is necessary to adjust the relative position between the first shaft tube 4 and the second shaft tube 6, the screw post 511 screwed on the adjusting seat 506 is first controlled to disengage from the socket, and then the bevel gear ring 510 is rotated. The bevel gear ring 510 meshes with multiple bevel gears 509 and rotates synchronously. The multiple bevel gears 509 drive multiple screw rods 508 to rotate. When the multiple screw rods 508 rotate, they change their contact position with the multiple adjusting seats 506, thereby causing the multiple adjusting seats 506 to move towards or away from the axis of the fixed plate 507 in the multiple adjusting slides on the fixed plate 507. When the seat 506 moves, it changes the position of its connection with the multiple adjusting arms 505. The other end of the multiple adjusting arms 505 drives the pressure ring 503 to slide on the first shaft tube 4. When the first shaft tube 4 slides, it drives the moving flange 501 to move through the multiple shafts 504. The moving flange 501 drives the second shaft tube 6 to move closer to or away from the first shaft tube 4, thereby adjusting the rolling position of the material. After adjustment, the screw post 511 screwed on the control adjusting seat 506 can be inserted into a socket to complete the fixation. The two ends of the tension spring sleeved on the first shaft tube 4 are respectively connected to the fixed flange 502 and the pressure ring 503, which helps to improve the stability of the fixed flange 502 and the pressure ring 503 after relative movement.

[0049] Example 5

[0050] Please see Figures 1-9The reinforcing connector 7 includes: a reinforcing seat 701 connected to the second shaft tube 6 and a reinforcing shaft 702 fixed on the reinforcing seat 701. Multiple cable partitions 703 are fixed around the reinforcing shaft 702. Multiple arc-shaped baffles 704 fixed on the multiple cable partitions 703 are slidably disposed in the cable routing channel of the first shaft tube 4 and the output shaft of the precision reducer 2.

[0051] The working principle and technical effect of the above technical solution are as follows: The reinforcing seat 701 of the reinforcing connector 7 is connected to the second shaft tube 6, and the reinforcing shaft 702 is fixed on the reinforcing seat 701, thus establishing an additional and stable connecting bridge between the first shaft tube 4 and the second shaft tube 6; during the transmission process, it can effectively disperse torque and stress, reduce vibration and offset caused by transmission, making the power transmission from the first shaft tube 4 to the second shaft tube 6 more stable and reliable, reducing the risk of equipment failure caused by unstable power transmission, and ensuring the normal operation of the entire tumble soaking machine tilting control system; multiple arc-shaped baffles 704 are combined with cable partitions 703, and the multiple arc-shaped baffles 704 are slidably installed in the inner wall of the first shaft tube 4 and the cable routing channel of the output shaft of the precision reducer 2, providing good support for the reinforcing connector 7; when the first shaft tube 4 rotates, the arc-shaped baffles 704 can slide along a specified path, further constraining the movement trajectory of the reinforcing connector 7, preventing unnecessary shaking and swaying, thereby enhancing the connection between the first shaft tube 4 and the second shaft tube 6. The stability of the transmission control between the shaft tubes 6 ensures the precise rotation of the tilting shaft and the stable tumbling of materials. The multiple cable partitions 703 fixed around the reinforcing shaft 702 play an important role in cable separation. During the operation of the electric tumbling machine, various wires and signal lines may be arranged in the cable routing channel. The cable partitions 703 can separate cables of different types and purposes, avoiding tangling and interference between cables, making the cable layout more neat and orderly, and facilitating subsequent equipment maintenance and troubleshooting. The structural design of the reinforcing connector 7 cleverly utilizes the space of the cable routing channel between the inner wall of the first shaft tube 4 and the output shaft of the precision reducer 2. By rationally arranging components such as the reinforcing seat 701, reinforcing shaft 702, cable partitions 703, and arc-shaped baffles 704 in this limited space, it not only enhances the transmission stability but also completes the task of cable management and protection, avoiding additional space occupation of the equipment, making the entire tumbling machine structure more compact and improving the space utilization rate of the equipment.
