Description

Technical Field

[0001] This invention relates to the field of internal mixer technology, and more specifically to a meshing type tilting internal mixer. Background Technology

[0002] Internal mixers are key mixing equipment in the field of polymer material processing. Their core function is to apply shearing, extrusion, and kneading forces to materials such as rubber, plastics, and masterbatches through the relative movement of one or more pairs of rotors within the barrel. This allows materials of different components to achieve uniform mixing, plasticization, and dispersion under high temperature and high pressure. They are an indispensable core piece of equipment in the production processes of tires, seals, and plastic profiles, and are widely used in the rubber industry, plastics processing industry, and composite material manufacturing. Among the sub-types of internal mixers, the meshing-type tilting internal mixer improves mixing uniformity through the meshing structure between the rotors. Simultaneously, it achieves rapid unloading through the overall tilting of the mixing chamber, balancing mixing quality with simplified unloading operations. Therefore, it is commonly used in small-batch, multi-variety material processing scenarios and is one of the commonly used pieces of equipment in small and medium-sized rubber and plastic processing enterprises.

[0003] However, in existing meshing-type reversible internal mixers, the resistance of the meshing rotor to the material during the meshing process is much greater than that of the tangential rotor. The combination of asynchronous motor and ordinary gear transmission commonly used in existing equipment is prone to speed fluctuations due to excessively high load peaks. This not only weakens the continuous shearing force on the material but also leads to disordered mixing rhythm, affecting the uniformity of the final rubber compound. In addition, the shearing action of the meshing rotor causes the material to release a large amount of frictional heat in a short period of time. However, existing internal mixing chambers mostly adopt a single-cavity cooling structure with a small heat exchange area and slow heat dissipation, making it difficult to accurately control the mixing temperature within the optimal range for rubber processing (usually 120-150℃). If the temperature exceeds the critical value, it can easily cause the rubber molecular chain to break or scorch, leading to deterioration of the rubber compound performance and an increase in scrap rate. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a meshing type tilting internal mixer to solve the problems of poor load adaptability and inaccurate temperature control of the existing meshing type tilting internal mixer.

[0014] The beneficial effects of this invention are as follows: 1. By adopting a drive module structure that combines a permanent magnet synchronous motor with a main gear and three auxiliary gears, the main gear is driven to rotate by the permanent magnet synchronous motor, and the three auxiliary gears simultaneously mesh with the main gear and the teeth inside the semi-enclosed gear ring housing, driving the transmission disc to rotate smoothly. In turn, the transmission mechanism drives the meshing rotor in the mixing chamber to rotate synchronously. The permanent magnet synchronous motor has the characteristics of low speed, high torque and strong speed stability, which can effectively resist the high load generated when the meshing rotor bites the material, avoid speed fluctuations caused by excessive load peaks, ensure the application of continuous and stable shear force to the material, and ensure the consistency of the mixing rhythm. This solves the problems of speed fluctuations, weakened shear force and disordered mixing rhythm that are easy to occur in the existing asynchronous motor + ordinary gear transmission combination, and improves the mixing uniformity of the rubber compound. 2. By using a stacked corrugated pipe installed on the inner wall of the outer layer of the mixing chamber, along with a cooling box, a water pump, and a circulation pipe, and in conjunction with a second temperature sensor, a third temperature sensor, a fourth temperature sensor in the middle of the heat-conducting liner on the inner wall of the mixing chamber, and a first temperature sensor on the second circulation pipe, the stacked corrugated pipe significantly increases the heat exchange area. The water pump pumps the coolant from the cooling box into the corrugated pipe, and the frictional heat inside the mixing chamber is removed through heat exchange. The second, third, and fourth temperature sensors monitor the material temperature at different locations inside the mixing chamber in real time, and the first temperature sensor detects the temperature of the discharged coolant. Multiple sets of temperature data are fed back to the controller, which adjusts the power of the water pump and the solenoid valve switch according to the temperature difference, accurately controlling the coolant circulation rate and heat exchange efficiency, and realizing dynamic regulation of the mixing temperature. This keeps the temperature stable within the optimal range of 120-150℃ for rubber processing, avoiding the temperature runaway problems caused by the small heat exchange area, slow heat dissipation, and incomplete temperature monitoring of existing single-cavity cooling structures. This prevents rubber molecular chain breakage or scorching, reduces the scrap rate, and ensures the performance of the rubber compound. 3. Through the cooperation of the stepper motor and rotating shaft in the flipping component, combined with the synergistic effect of the drive module and temperature control module, the stepper motor precisely controls the rotation of the rotating shaft through the controller, driving the mixing chamber to achieve stable flipping. During the mixing process, the drive module ensures continuous and efficient mixing of the rotor, while the temperature control module maintains stable temperature. After mixing is completed, the material is quickly unloaded through the flipping component. This retains the advantage of the meshing rotor in improving mixing quality, while the combination of permanent magnet synchronous motor and multi-gear transmission solves the problem of unstable operation caused by excessive load. The combination of laminated corrugated pipe and multi-point temperature monitoring solves the problem of inaccurate temperature control, and simplifies the unloading operation. It meets the needs of small and medium batch and multi-variety material processing scenarios, and avoids problems such as low mixing efficiency, poor rubber quality, and cumbersome unloading caused by equipment performance defects, thereby improving the stability and practicality of the overall processing flow.

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] Example: Please see Figures 1 to 7A meshing type tilting internal mixer includes a base 1, characterized in that: a mixing chamber 10 is provided above the base 1, a pressing mechanism 4 is bolted to the upper surface of the base 1 above the mixing chamber 10, a cooling box 6 is connected to the upper surface of the base 1, a temperature control module is provided on the right side of the cooling box 6, a controller 7 is fixedly connected to the front of the cooling box 6, the controller 7 is a PLC programmable logic controller, a tilting component is provided above the base 1 on the left side of the mixing chamber 10, a permanent magnet synchronous motor 3 is bolted to the upper surface of the base 1, a drive module is connected to the output end of the permanent magnet synchronous motor 3, and the drive module is connected to the right side of the mixing chamber 10; The drive module includes a semi-enclosed gear ring housing 2 connected to the upper surface of the base 1. A first ball bearing 11 is fixedly connected to the inner right side of the semi-enclosed gear ring housing 2. A drive shaft 28 is fixedly connected to the inner ring of the first ball bearing 11. A main gear 26 is connected to the outer surface of the drive shaft 28. Three auxiliary gears 25 are meshed on the outer circumferential surface of the main gear 26. A connecting shaft 29 is connected to the left side of each auxiliary gear 25. A second ball bearing 24 is fixedly connected to the outer surface of the left end of each connecting shaft 29. A transmission disk 30 is connected to the outer surface of the three second ball bearings 24. A transmission mechanism is provided on the left side of the transmission disk 30. The left side of the semi-enclosed gear ring housing 2 is open. The diameters of the three auxiliary gears 25 are all larger than the diameter of the main gear 26. The outer circumferential surface of each auxiliary gear 25 meshes with the inner teeth of the semi-enclosed gear ring housing 2. The left end of each connecting shaft 29 extends to the outside of the semi-enclosed gear ring housing 2. The right end of the drive shaft 28 is fixedly connected to the output end of the permanent magnet synchronous motor 3. The controller 7 is electrically connected to the permanent magnet synchronous motor 3 through wires.

[0019] Working principle: The permanent magnet synchronous motor 3 is started by the controller 7. The output end of the permanent magnet synchronous motor 3 drives the drive shaft 28 to rotate. The drive shaft 28 rotates stably under the support of the first ball bearing 11, which in turn drives the main gear 26 on the outer surface to rotate synchronously. The main gear 26 meshes with three auxiliary gears 25, and the three auxiliary gears 25 mesh with the internal teeth of the semi-enclosed gear ring housing 2 at the same time, so that the auxiliary gears 25 revolve around the main gear 26 while rotating on their own axis. The auxiliary gears 25 drive the second ball bearing 24 and the transmission disk 30 to rotate smoothly through the connecting shaft 29. The transmission mechanism receives the power of the transmission disk 30 and transmits it to the inside of the mixing chamber 10, providing stable power for material mixing. The pressing mechanism 4 can prevent the material from overflowing during mixing. The cooling box 6 and the temperature control module ensure stable mixing temperature. The flipping component facilitates subsequent unloading, realizing efficient mixing of materials. It solves the problem that the speed fluctuation of the existing asynchronous motor + ordinary gear transmission combination is prone to excessive load peak, ensuring stable mixing rhythm.

[0020] Please see Figures 1 to 7The transmission mechanism includes a transmission box 22 located on the right side of the mixing chamber 10 and the left side of the transmission disk 30. A third ball bearing 12 and a fourth ball bearing 31 are symmetrically connected to the inner wall of the right side of the transmission box 22. The inner rings of the third ball bearing 12 and the fourth ball bearing 31 are respectively fixedly connected to a first transmission shaft 13 and a second transmission shaft 23. The left ends of the first transmission shaft 13 and the second transmission shaft 23 are respectively fixedly connected to a first transmission wheel 14 and a second transmission wheel 27. The left side of the first transmission wheel 14 and the left side of the second transmission wheel 27 are both fixedly connected to a meshing rotor 16. The inner wall of the left side of the transmission box 22 is connected to a fifth ball bearing 15 corresponding to the meshing rotor 16. The right side of the mixing chamber 10 and the left side of the transmission box 22 are connected together to four stabilizing rods 21. The inner walls of the left and right sides of the mixing chamber 10 are connected to four sealed bearings 17 corresponding to the fifth ball bearing 15. The right end of the first transmission shaft 13 is connected to the left side of the transmission disk 30. The right end of the first drive shaft 13 extends to the right side of the transmission box 22. The inner ring of each fifth ball bearing 15 is fixedly connected to the shaft surface of the meshing rotor 16. The meshing end of each meshing rotor 16 extends into the interior of the mixing chamber 10. The inner ring of each sealed bearing 17 is connected to the outer surfaces on both sides of the meshing end of the meshing rotor 16.

[0021] Working principle: When the transmission disc 30 rotates, it drives the first transmission shaft 13 to rotate. The first transmission shaft 13 operates stably under the support of the third ball bearing 12. At the same time, through transmission cooperation, it drives the second transmission shaft 23 to rotate synchronously in the fourth ball bearing 31. The first transmission shaft 13 and the second transmission shaft 23 drive the first transmission wheel 14 and the second transmission wheel 27 on the left end to rotate, which in turn drives the meshing rotor 16 to rotate stably under the cooperation of the fifth ball bearing 15 and the sealed bearing 17. The meshing end of the meshing rotor 16 applies shearing, squeezing and kneading forces to the material in the mixing chamber 10. The four stabilizing rods 21 enhance the connection stability between the transmission box 22 and the mixing chamber 10. The sealed bearing 17 prevents material leakage. Through the cooperation of the transmission structure and the drive module, the stability of the operation of the meshing rotor 16 and the efficiency of power transmission are ensured. This solves the problems of insufficient shearing force and poor mixing uniformity of existing equipment, and improves the mixing quality of rubber compound.

[0022] Please see Figures 1 to 7 The flipping assembly includes a support frame 9 connected to the upper surface of the base 1. A stepper motor 8 is bolted to the left side of the support frame 9. A sixth ball bearing 19 is fixedly connected to the inner wall of the top of the support frame 9 to the right side of the stepper motor 8. A rotating shaft 18 is fixedly connected to the output end of the stepper motor 8 and the inner ring of the sixth ball bearing 19. The right end of the rotating shaft 18 is connected to the left side of the mixing chamber 10. The controller 7 is electrically connected to the stepper motor 8 through wires.

[0023] Working principle: After the material is mixed, the controller 7 starts the stepper motor 8, which drives the rotating shaft 18 to rotate. The rotating shaft 18 runs smoothly under the support of the sixth ball bearing 19. The right end of the rotating shaft 18 is connected to the left side of the mixing chamber 10, thereby driving the mixing chamber 10 to rotate as a whole, realizing rapid unloading. This component cooperates with the support frame 9 on the base 1 to provide stable support for the rotation of the mixing chamber 10. The stepper motor 8 can be precisely controlled by the controller 7 to control the rotation angle and speed, avoiding material residue or spillage during unloading.

[0024] Please see Figures 1 to 7 The temperature control module includes a water pump 5 fixedly connected to the upper surface of the cooling box 6. The input end of the water pump 5 extends into the interior of the cooling box 6. The output end of the water pump 5 is fixedly connected to the first circulation pipe 38. The right side of the bottom of the cooling box 6 is fixedly connected to the second circulation pipe 36. The outer inner wall of the mixing chamber 10 is connected to a corrugated pipe 32 arranged in a stacked manner. The inlet and outlet ends of the corrugated pipe 32 are fixedly connected to the right end of the first circulation pipe 38 and the right end of the second circulation pipe 36, respectively. The outer surfaces of the first circulation pipe 38 and the second circulation pipe 36 are respectively fixedly connected to the solenoid valve 37 and the first temperature sensor 35. The inner wall of the mixing chamber 10 is connected to the heat-conducting liner 39 by high-temperature resistant sealant. The heat-conducting liner 39 can be made of copper alloy and has high thermal conductivity, which can quickly transfer heat from the wall of the mixing chamber 10 to the bellows 32 to achieve ±3℃ temperature control. The inner wall of the heat-conducting liner 39 is connected to the second temperature sensor 40 and the third temperature sensor 41, which are symmetrically connected. The inner wall of the middle part of the mixing chamber 10 is connected to the fourth temperature sensor 20. The second temperature sensor 40 is set at the top of the mixing chamber 10. The controller 7 is electrically connected to the water pump 5, the solenoid valve 37, the first temperature sensor 35, the second temperature sensor 40, the third temperature sensor 41 and the fourth temperature sensor 20 by wires.

[0025] Working principle: During the mixing process, the second temperature sensor 40, the third temperature sensor 41, and the fourth temperature sensor 20 monitor the material temperature at the top, bottom, and middle of the mixing chamber 10 in real time, respectively. The first temperature sensor 35 detects the temperature of the coolant discharged from the second circulation pipe 36. All temperature data are fed back to the controller 7. When the temperature exceeds the optimal range of 120-150℃, the controller 7 controls the water pump 5 to start, pumping the coolant in the cooling tank 6 into the stacked corrugated pipe 32 through the first circulation pipe 38. The corrugated pipe 32 increases the heat exchange area and quickly removes the frictional heat in the mixing chamber 10. The cooled coolant after heat exchange flows back to the cooling tank 6 through the second circulation pipe 36. The controller 7 adjusts the opening of the solenoid valve 37 and the power of the water pump 5 according to the temperature data to accurately control the coolant circulation rate. The heat-conducting liner 39 enhances the heat transfer efficiency. Through the cooperation of the temperature control module and the mixing chamber 10, the problems of small heat exchange area, slow heat dissipation, and inaccurate temperature control of the existing single-cavity cooling structure are solved, avoiding the breakage or scorching of rubber molecular chains and ensuring the performance of the rubber compound.

[0026] Please see Figures 1 to 7 A water injection pipe 33 is fixedly connected to the upper surface of the cooling box 6, and a water level sensor 34 is fixedly connected to the upper wall inside the cooling box 6. The controller 7 is electrically connected to the water level sensor 34 through a wire.

[0027] Working principle: Coolant can be added to the cooling tank 6 through the water injection pipe 33. The water level sensor 34 on the inner wall of the upper surface of the cooling tank 6 monitors the coolant level in the tank in real time. When the water level is lower than the set threshold, the water level sensor 34 feeds back the signal to the controller 7. The controller 7 can issue a warning signal to remind the operator to add water in time to ensure that the temperature control module has sufficient coolant. This avoids the problem of reduced heat exchange efficiency and temperature runaway due to insufficient coolant, and ensures the continuous and stable operation of the temperature control module, providing a stable temperature environment for material mixing.

[0028] Working principle: In use, sufficient coolant is first injected into the cooling tank 6 through the water injection pipe 33. The water level sensor 34 monitors the coolant level in the cooling tank 6 in real time and feeds the data back to the controller 7 to ensure that the subsequent temperature control module has a sufficient supply of coolant. Then, the controller 7 controls the start of the permanent magnet synchronous motor 3. The output end of the permanent magnet synchronous motor 3 drives the drive shaft 28 to rotate. The drive shaft 28 rotates stably under the support of the first ball bearing 11, which in turn drives the main gear 26 on the outer surface to rotate synchronously. The main gear 26 meshes with three auxiliary gears 25, and the three auxiliary gears 25 simultaneously mesh with the internal teeth of the semi-enclosed gear ring housing 2, so that the auxiliary gears 25 revolve around the main gear 26 while rotating on their own axis. The auxiliary gear 25 drives the second ball bearing 24 and the transmission disk 30 to rotate smoothly via the connecting shaft 29. When the transmission disk 30 rotates, it drives the first transmission shaft 13 to rotate. The first transmission shaft 13 operates stably under the support of the third ball bearing 12. At the same time, through transmission cooperation, it drives the second transmission shaft 23 to rotate synchronously within the fourth ball bearing 31. The first transmission shaft 13 and the second transmission shaft 23 respectively drive the first transmission wheel 14 and the second transmission wheel 27 at the left end to rotate, thereby driving the meshing rotor 16 to rotate stably under the cooperation of the fifth ball bearing 15 and the sealed bearing 17. The axes of the drive shaft 28, the first transmission shaft 13, the meshing rotor 16, and the rotating shaft 18 are all on the same horizontal line, ensuring that... The power transmission is smooth and facilitates the subsequent turning operation of the mixing chamber 10. The meshing end of the meshing rotor 16 applies shearing, squeezing, and kneading forces to the material inside the mixing chamber 10. The pressing mechanism 4 prevents the material from overflowing during mixing. Four stabilizing rods 21 enhance the connection stability between the transmission box 22 and the mixing chamber 10. During the mixing process, the second temperature sensor 40, the third temperature sensor 41, and the fourth temperature sensor 20 monitor the material temperature at the top, bottom, and middle of the mixing chamber 10, respectively. The first temperature sensor 35 detects the temperature of the coolant discharged from the second circulation pipe 36. All temperature data is fed back to the controller 7. If the temperature exceeds the optimal range of 120-150℃, the controller 7 controls the water pump. 5. Upon startup, the coolant in the cooling tank 6 is pumped into the stacked corrugated pipe 32 through the first circulation pipe 38. The corrugated pipe 32 increases the heat exchange area and quickly removes heat. The coolant after heat exchange flows back through the second circulation pipe 36. The controller 7 can also adjust the opening of the solenoid valve 37 and the power of the water pump 5 to precisely control the circulation rate. When the material is mixed, the controller 7 sends a command to the stepper motor 8. The stepper motor 8 starts and drives the rotating shaft 18 to run smoothly under the support of the sixth ball bearing 19. This, in turn, drives the mixing chamber 10 to rotate as a whole to achieve rapid unloading. This solves the problems of speed fluctuation, inaccurate temperature control, and cumbersome unloading in existing equipment, ensuring efficient and uniform mixing of materials and guaranteeing stable performance of the rubber compound.
