Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical mixers, in particular to a cylindrical mixer with adjustable inclination angle. Background Technique

[0002] A cylindrical mixer (also known as a drum mixer) is a mechanical device widely used in industries such as chemical engineering, pharmaceuticals, food, metallurgy, and building materials. It is mainly used for uniformly mixing various materials (such as powders, granules, liquids, etc.). Its core structure is a rotating cylinder. Through the rotation of the cylinder body and the movement of the internal materials, technological purposes such as material mixing, granulation, or drying are achieved.

[0003] The cylindrical mixer realizes material mixing in the following ways: Gravity effect: As the cylinder body rotates, the materials rise to a certain height and then freely fall under the action of gravity, forming a "material waterfall" to promote the diffusion mixing between materials; Shearing effect: The materials rub and squeeze against each other during the rolling process, generating shear force to further refine the mixing effect; Diffusion effect: Different materials are gradually dispersed and evenly mixed during repeated tumbling, achieving mixing at both the macroscopic and microscopic levels. The cylindrical mixer mainly consists of the following parts: Cylinder body: Usually cylindrical or conical, the inner wall can be designed to be smooth or equipped with lifters (lifting blades) to enhance the material turning effect; Transmission device: Includes a motor, gear, or chain drive system to drive the rotation of the cylinder body; Support device: Uses idler wheels or rings to support the cylinder body to ensure its stable rotation; Inlet and outlet: Generally set at both ends of the cylinder body, and some models are equipped with a sealing device to prevent dust leakage.

[0004] At the current stage, for the cylindrical mixers on the market, by adjusting the inclination angle of the cylinder body, the mixing effect and production efficiency can be significantly optimized to meet the technological requirements of different materials. Because the inclination angle adjustment can change the residence time and movement trajectory of the materials in the cylinder body. Small inclination angle (0° - 3°): The materials roll slowly, suitable for light and fragile materials (such as food powders) to reduce breakage; Large inclination angle (5° - 8°): The material flow accelerates, suitable for materials with large specific gravity differences (such as ore powder and additives) to avoid stratification. For example, in the mixing of ceramic raw materials, after the inclination angle increases from 3° to 5°, the deviation of alumina content drops from ±2.5% to ±1.2%; A pharmaceutical enterprise changed the fixed inclination angle of 4° to adjustable, and the mixing time was shortened by 20% - 30%. Therefore, the adjustable inclination angle design of the cylindrical mixer significantly improves the mixing efficiency, product quality, and production flexibility by dynamically optimizing the material movement state, and is an indispensable technological innovation in modern industrial production.

[0005] For the cylinder mixer in the currently disclosed technologies, although the adjustment operation of the cylinder angle can be achieved. For example, the utility model patent with the authorized public number CN213726111U discloses a roll ring inclination angle adjustment structure of a cylinder mixer, including a base that can adjust the lifting angle, and a bracket is assembled on the upper surface of the base, which solves the problem of inconvenient angle adjustment of the existing cylinder mixer.

[0006] However, when adjusting the cylinder angle of its device, since the rotation axis point of the cylinder is set at the end of the substrate, the torque is relatively large during the rotation of the cylinder. Therefore, a greater force is required to achieve rotation. This design not only increases the operation intensity of the drive motor but also makes the overall structure less reasonable. In addition, after the angle adjustment is completed, due to the large overall weight of the mixer, when relying solely on the self-locking function of the drive motor itself for fixation, the meshing and tightening force of the self-locking teeth is relatively high. After long-term use, it is easy to cause damage to the self-locking function of the motor, which requires motor repair or even replacement, causing trouble and high costs. Summary of the Invention

[0007] The purpose of the present utility model is to provide a cylinder mixer with adjustable inclination angle. The rotation axis center point of the machine body is located near the center position, which can greatly reduce the torque during the rotation of the machine body, reduce the driving force required during rotation. In addition, after the angle adjustment is completed, the motor no longer bears the self-locking burden, greatly improving the service life of the motor. When the self-locking structure is damaged during long-term use, it can be quickly replaced, significantly reducing the maintenance cost of equipment operation, so as to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present utility model provides the following technical solutions: a cylindrical mixer with adjustable inclination angle, comprising a base plate, a support plate and a machine body. A support plate is provided above the base plate, and the machine body is mounted on the upper surface of the support plate. The machine body is connected to the base plate through a support unit. The support unit includes: a cylinder, which is rotatably connected to the outer wall of the machine body. Cylinders are fixedly connected to both the front and rear sides of the outer wall of the cylinder. The outer wall of the cylinder is rotatably connected to a vertical plate, and the bottom end of the vertical plate is fixedly connected to the base plate. A box body is provided on the front side of the cylinder, and the box body is fixedly connected to the vertical plate. A worm gear is provided inside the box body, and the worm gear is sleeved on the outer wall of the front cylinder. A plurality of key blocks are fixedly connected to the inner wall of the worm gear, and the key blocks are inserted into the cylinder through key grooves. A plurality of grooves are provided at the front end of the front cylinder, and a first bolt is provided inside the grooves. A part of the first bolt penetrates through the cylinder and abuts against the inner wall of the worm gear. A worm is meshed with the top end of the worm gear. One end of the worm is attached to a first horizontal shaft, and a second bolt is inserted into the other end of the worm. The second bolt penetrates through the worm and is threadedly connected to the first horizontal shaft. One end of the first horizontal shaft is provided with a second horizontal shaft, and the second horizontal shaft is connected to the first horizontal shaft through a coupling. The second horizontal shaft is rotatably connected to the box body through a ball bearing. The end of the second horizontal shaft away from the coupling is fixedly connected to a motor, and the motor is fixedly connected to the box body.

[0009] Preferably, a pair of insertion rods are fixedly connected to the end of the first horizontal shaft close to the worm. The insertion rods are inserted into the worm through slots, and the pair of insertion rods are symmetrically arranged with respect to the center point of the worm.

[0010] Preferably, an anti-slip block is fixedly connected to the end of the first bolt close to the worm gear, and the anti-slip block abuts against the inner wall of the worm gear.

[0011] Preferably, the coupling is a YL type flange coupling.

[0012] Preferably, an auxiliary unit is provided between the base plate and the support plate: the auxiliary unit includes: a pair of vertical cylinders, and the pair of vertical cylinders are located on both sides between the base plate and the support plate. A vertical rod is provided inside the vertical cylinder. U-shaped blocks are hinged to the ends of the vertical rod and the vertical cylinder away from each other. The upper U-shaped block is fixedly connected to the support plate, and the lower U-shaped block is fixedly connected to the base plate. A third bolt is threadedly connected to the outer wall of the vertical cylinder, and a part of the third bolt penetrates through the vertical cylinder and abuts against the vertical rod.

[0013] Preferably, a friction strip is processed on the outer wall of the vertical rod, and the friction strip abuts against the end of the third bolt.

[0014] Compared with the prior art, the beneficial effects of the present utility model are: the cylindrical mixer with adjustable inclination angle has the following advantages compared with the traditional technology:

[0015] Through the cooperation among the base plate, the supporting plate, the machine body and the supporting unit, the user drives the motor to rotate its output shaft. Through the transmission of the second horizontal shaft, the coupling and the second horizontal shaft, the worm rotates accordingly. The rotating worm meshes with the worm wheel for transmission. Since the worm wheel is connected to the cylinder through the key block and the key groove, and the cylinder rotates synchronously with the machine body, the angle adjustment of the machine body is realized. During this process, the rotation axis point (cylinder) of the machine body is located at a relatively central position of its whole, which can significantly reduce the rotation torque, lower the acting force required for driving, and further reduce the load of the motor, which is beneficial to the long-term stable operation of the motor;

[0016] Through the cooperation among the base plate, the supporting plate, the machine body and the supporting unit, after the angle adjustment of the machine body is completed, the motor operation is stopped. Since the worm and the worm wheel have a self-locking function, the system can automatically maintain the current angle without the motor continuously outputting torque. After long-term operation, if the angle adjustment accuracy of the machine body decreases due to the wear of the meshing teeth of the worm and the worm wheel, the following steps can be taken for maintenance: drive the motor to rotate the transmission system to the maximum adjustable angle. At this time, the base plate, the vertical plate and the cylinder jointly bear the weight of the machine body to ensure the structural stability. Perform the operation of opening the front side movable door of the box body, and loosen the first bolt and the second bolt counterclockwise in turn, then the worm and the worm wheel can be disassembled and replaced. This maintenance process does not require replacing the motor, only locally disassembling and assembling the transmission components, with simple operation and low cost, which can effectively reduce the maintenance cost of the equipment throughout its life cycle;

[0017] Through the cooperation among the base plate, the supporting plate, the machine body, the supporting unit and the auxiliary unit, after the angle adjustment of the machine body is completed and the motor operation is stopped, the user can tighten the third bolt clockwise to make it closely fit with the outer wall of the vertical rod. At this time, an un-slidable state is formed between the vertical rod and the vertical cylinder, providing a stable supporting force for the bottom end of the supporting plate, thereby assisting the machine body to maintain overall stability. This supporting structure can reduce the load pressure at the meshing part of the worm wheel and the worm by sharing part of the load of the machine body, thereby reducing the wear of the transmission components, extending the equipment maintenance cycle and reducing the maintenance frequency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7, the present utility model provides a technical solution: a cylindrical mixer with adjustable inclination angle, which includes a base plate 1, a support plate 2 and a machine body 3. A support plate 2 is arranged above the base plate 1, and the machine body 3 is installed on the upper surface of the support plate 2. The machine body 3 is connected to the base plate 1 through a support unit. The support unit includes: a cylinder 4, the cylinder 4 is rotatably connected to the outer wall of the machine body 3. Cylinders 8 are fixedly connected to both the front and rear sides of the outer wall of the cylinder 4. The outer wall of the cylinder 8 is rotatably connected to a vertical plate 5, and the bottom end of the vertical plate 5 is fixedly connected to the base plate 1. A box body 6 is arranged on the front side of the cylinder 4, and the box body 6 is fixedly connected to the vertical plate 5. A worm gear 7 is arranged inside the box body 6, and the worm gear 7 is sleeved on the outer wall of the front cylinder 8. A plurality of key blocks 10 are fixedly connected to the inner wall of the worm gear 7, and the key blocks 10 are inserted into the cylinder 8 through key grooves 9. A plurality of grooves 11 are opened at the front end of the front cylinder 8, and a first bolt 12 is arranged inside the grooves 11. A part of the first bolt 12 penetrates through the cylinder 8 and abuts against the inner wall of the worm gear 7. A worm 13 is meshed with the top end of the worm gear 7. A first horizontal shaft 14 is attached to one end of the worm 13, and a second bolt 15 is inserted into the other end of the worm 13. The second bolt 15 penetrates through the worm 13 and is threadedly connected to the first horizontal shaft 14. A second horizontal shaft 16 is arranged at one end of the first horizontal shaft 14. The second horizontal shaft 16 is connected to the first horizontal shaft 14 through a coupling 17. The second horizontal shaft 16 is rotatably connected to the box body 6 through a ball bearing. A motor 18 is fixedly connected to the end of the second horizontal shaft 16 away from the coupling 17, and the motor 18 is fixedly connected to the box body 6.

[0029] In the specific implementation process, it is particularly worth noting that the machine body 3 is a cylindrical mixer, which mainly consists of the following parts: the cylinder body: usually cylindrical or conical, and the inner wall can be designed to be smooth or equipped with flight bars (lifting blades) to enhance the material turning effect; the transmission device: including a motor, a gear or chain drive system to drive the cylinder body to rotate; the supporting device: using idler wheels or rings to support the cylinder body to ensure its stable rotation; the feeding and discharging ports: generally set at both ends of the cylinder body, and some models are equipped with a sealing device to prevent dust leakage. It is a mechanical device widely used in industries such as chemical engineering, pharmaceuticals, food, metallurgy, and building materials, mainly used for uniformly mixing various materials (such as powders, granules, liquids, etc.). The cylinder 4 is rotationally connected to the cylinder body in the machine body 3 through a ball bearing, the cylinder 8 is rotationally connected to the vertical plate 5 through a ball bearing. The front side of the box body 6 is provided with a movable door, which can open the box body 6 during maintenance. The movable door is in a closed state for the box body 6 during equipment operation. The worm wheel 7 and the worm 13 are connected through meshing, forming a mechanical connection method with self-locking, large transmission ratio, and spatial intersecting axis transmission characteristics. The worm 13 is a helical tooth driving part, and the worm wheel 7 is an inclined gear driven part. The axes of the two are at a 90° angle to achieve spatial vertical transmission. The tooth surface of the worm 13 is a continuous spiral line, and the tooth surface of the worm wheel 7 is an involute helical surface. When meshing, it forms a line contact (compared with the point contact of gear transmission), with stronger load-bearing capacity. The meshing point moves along the axial direction of the worm 13, forming a compound friction of sliding + rolling (the sliding friction coefficient is usually 0.05 - 0.1), and lubrication is required to reduce the temperature rise. When the lead angle γ of the worm 13 is less than the equivalent friction angle ρv, the worm wheel 7 cannot drive the worm 13 in the reverse direction, realizing one-way braking. Both the worm wheel 7 and the worm 13 are made of high-strength alloy steel, which can significantly improve the tooth surface hardness and wear resistance, thereby enhancing the load-bearing capacity, and can meet requirements such as bridge inspection and heavy machinery, and it is necessary to select a load-bearing capacity of 5 tons to more than 30 tons. The first bolt 12 is threadedly connected to the penetration surface of the cylinder 8. After the first bolt 12 abuts against the worm wheel 7, the stability between the worm wheel 7 and the cylinder 8 can be improved. The output shaft of the motor 18 is fixedly connected to the second horizontal shaft 16. The motor 18 is a servo motor, and the specific model is not limited, as long as it can meet the usage requirements. As the core component of high-precision motion control, the technical advantages of the servo motor run through the core scenarios in fields such as industrial automation, precision manufacturing, and high-end equipment. The housing of the motor 18 is fixedly connected to the box body 6, and the power cord of the motor 18 is connected to an external power supply device to provide the electric energy required for the operation of the motor 18.

[0030] Further, a pair of insertion rods 19 are fixedly connected to the end of the first horizontal shaft 14 close to the worm 13. The insertion rods 19 are inserted and connected to the worm 13 through slots 20, and the pair of insertion rods 19 are symmetrically arranged with respect to the center point of the worm 13.

[0031] In the specific implementation process, it is particularly worth noting that the outer wall of the insertion rod 19 and the inner wall of the insertion slot 20 are in clearance fit. Clearance fit refers to a fit with a clearance (including the minimum clearance equal to zero). The end of the insertion rod 19 close to the worm 13 is of a conical structure. The arrangement of the insertion rod 19 and the insertion slot 20 facilitates the axial drive of the worm 13 by the first cross shaft 14.

[0032] Furthermore, an anti-slip block 21 is fixedly connected to the end of the first bolt 12 close to the worm wheel 7, and the anti-slip block 21 abuts against the inner wall of the worm wheel 7.

[0033] In the specific implementation process, it is particularly worth noting that the anti-slip block 21 is made of rubber material and has a certain flexibility. Due to the microscopic protrusions and pits on the surface of the rubber, these irregular shapes increase the contact area between the rubber and other objects, thereby increasing the friction force and improving the stability after the first bolt 12 abuts against the inner wall of the worm wheel 7.

[0034] Furthermore, the coupling 17 is a YL type flange coupling.

[0035] In the specific implementation process, it is particularly worth noting that the YL type flange coupling uses bolts to connect two flange (flange) disk type half couplings. The two half couplings are respectively connected to the two shafts with keys to realize the connection of the two shafts, transmit torque and motion. It has a simple structure, is easy to manufacture, has a low cost, is reliable in operation, is convenient for installation, disassembly and maintenance, can transmit a large torque, can ensure a high alignment accuracy of the two shafts, and can be disassembled when necessary to meet the smooth replacement of the worm 13 and the worm wheel 7.

[0036] Furthermore, an auxiliary unit is provided between the base plate 1 and the support plate 2: The auxiliary unit includes: a pair of vertical cylinders 22. The pair of vertical cylinders 22 are located on both sides between the base plate 1 and the support plate 2. A vertical rod 23 is provided on the inner wall of the vertical cylinder 22. U-shaped blocks 24 are hinged to the ends of the vertical rod 23 and the vertical cylinder 22 away from each other. The upper U-shaped block 24 is fixedly connected to the support plate 2, and the lower U-shaped block 24 is fixedly connected to the base plate 1. A third bolt 25 is threadedly connected to the outer wall of the vertical cylinder 22, and the third bolt 25 penetrates through a part of the vertical cylinder 22 and abuts against the vertical rod 23.

[0037] In the specific implementation process, it is particularly worth noting that the inner wall of the vertical cylinder 22 and the outer wall of the vertical rod 23 are in clearance fit. Clearance fit refers to a fit with a clearance (including the minimum clearance equal to zero). After completing the angle adjustment of the machine body 3 and stopping the operation of the motor 18, the user can tighten the third bolt 25 clockwise to make it closely fit with the outer wall of the vertical rod 23. At this time, an in-slidable state is formed between the vertical rod 23 and the vertical cylinder 22, providing a stable supporting force for the bottom end of the support plate 2, thereby assisting the machine body 3 to maintain overall stability.

[0038] Further, the outer wall of the vertical rod 23 is processed with friction stripes 26, and the friction stripes 26 are abutted against the end of the third bolt 25.

[0039] In the specific implementation process, it is particularly worth noting that the friction stripes 26 can improve the friction force on the outer wall of the vertical rod 23, and can improve the stability between the vertical rod 23 and the vertical cylinder 22 after the third bolt 25 abuts against the vertical rod 23.

[0040] Working principle:

[0041] Angle adjustment operation of the machine body:

[0042] The user drives the motor 18 to rotate its output shaft. Through the transmission of the second horizontal shaft 16, the coupling 17 and the first horizontal shaft 14, the worm 13 rotates accordingly. The rotating worm 13 meshes with the worm gear 7 for transmission. Since the worm gear 7 is connected to the cylinder 8 through the key block 10 and the key groove 9, and the cylinder 8 rotates synchronously with the machine body 3, the angle adjustment of the machine body 3 is realized;

[0043] In this process, the rotation axis point (cylinder 8) of the machine body 3 is located at the overall center position, which can significantly reduce the rotation torque, reduce the acting force required for driving, and further reduce the load of the motor 18, which is beneficial to the long-term stable operation of the motor 18;

[0044] Structural advantages: Central axis point design → Reduce torque → Reduce load → Prolong motor life.

[0045] Replacement operation of the adjustable transmission wearing parts:

[0046] After the angle adjustment of the machine body 3 is completed, the motor 18 is stopped. Since the worm 13 and the worm gear 7 have a self-locking function, the system can automatically maintain the current angle without the motor 18 continuously outputting torque;

[0047] After long-term operation, if the angle adjustment accuracy of the machine body 3 decreases due to the wear of the meshing teeth of the worm 13 and the worm gear 7, the following steps can be taken for maintenance:

[0048] 1. Drive the motor 18 to rotate the transmission system to the maximum adjustable angle. At this time, the base plate 1, the vertical plate 5 and the cylinder 8 jointly bear the weight of the machine body 3 to ensure the structural stability;

[0049] 2. Perform the operation of opening the front movable door of the box body 6, and sequentially loosen the first bolt 12 and the second bolt 15 counterclockwise, and then the worm 13 and the worm gear 7 can be separated and replaced;

[0050] This maintenance process does not require replacing the motor 18, only local disassembly and assembly of the transmission components. The operation is simple and the cost is low, which can effectively reduce the maintenance cost of the equipment throughout its life cycle;

[0051] Structural advantages: low cost, no need to replace the motor, and easy to operate.

[0052] Auxiliary support operation after adjusting the machine body:

[0053] After completing the angle adjustment of the machine body 3 and stopping the operation of the motor 18, the user can tighten the third bolt 25 clockwise to make it closely fit with the outer wall of the vertical rod 23. At this time, an in-slidable state is formed between the vertical rod 23 and the vertical cylinder 22, providing a stable supporting force for the bottom end of the support plate 2, thereby assisting the machine body 3 to maintain overall stability.

[0054] By sharing part of the load of the machine body 3, this support structure can reduce the load pressure at the meshing part of the worm gear 7 and the worm 13, thereby reducing the wear of the transmission components, extending the equipment maintenance cycle and reducing the maintenance frequency.

[0055] Structural advantages: sharing load → reducing the meshing load of the worm gear 7 - worm 13 → reducing wear → extending the maintenance cycle.
