Description

Technical Field

[0001] This utility model belongs to the technical field of planetary mixer equipment, specifically relating to a novel twisted blade for a dual planetary power mixer. Background Technology

[0002] In industries such as chemicals and rubber, mixers are often used for mixing. Planetary mixers are a new type of high-efficiency mixing equipment with no dead spots. They have a unique and novel mixing method. There are 2 to 3 stirring paddles and 1 to 2 automatic scrapers inside the vessel. While the stirring paddles revolve around the axis of the vessel, they also rotate at high speed around their own axis at different speeds. This causes the material to undergo complex movements inside the vessel and be subjected to strong shearing, which makes the mixing efficiency of the material several times that of ordinary mixers.

[0003] For example, in the Chinese utility model patent CN219784493U entitled "A Planetary Mixer", two sets of paddle shafts are equipped with planetary spiral blades at their ends, and a lifting drive is provided below the mixing pot and inside the frame. The above-mentioned prior art uses the mixing end cover to seal the mixing pot with each other. When mixing is required, the mixing end cover covers the mixing pot. The bottom of the existing mixing pot is not only flat, but also includes various shapes such as arc bottom and conical bottom. In the above-mentioned technical solution, it is difficult to mix the bottom of the mixing pot with an arc bottom. Therefore, if the bottom of the mixing pot is arc, the blades need to be replaced. So, in order to reduce the frequency of blade replacement and improve the mixing efficiency, a new type of spiral blade for a dual planetary power mixer is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a novel twisted blade for a dual planetary power mixer that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A novel twisted blade for a dual planetary power mixer includes a connecting shaft, a stirring mechanism at the bottom of the connecting shaft, two fixing components on the outer wall of the stirring mechanism, a limiting groove inside the connecting shaft, a threaded pin that slides through the stirring mechanism on the outside of the connecting shaft, and an arc-shaped plate at the bottom of the fixing components.

[0007] As a further optimization of this utility model, the stirring mechanism includes a fixed shaft disposed inside the connecting shaft, a twisted blade fixedly connected to the bottom of the fixed shaft, a flat key fixedly connected to the outside of the fixed shaft and abutting against a limiting groove opened at the bottom of the connecting shaft, and a limiting hole that cooperates with a threaded pin is opened inside the fixed shaft.

[0008] As a further optimization of this utility model, the sidewall of the twisted blade is provided with a ceramic coating, the bottom side of the twisted blade is provided with a tungsten carbide coating, and the top end of the connecting shaft is connected to the output shaft of the servo motor.

[0009] As a further optimization of this utility model, the fixing component includes two U-shaped fixing blocks 1 that abut against the bottom of the twisted blade, and two U-shaped fixing blocks 2 that are rotatably connected to one side of each of the two U-shaped fixing blocks 1. The bottom of the two U-shaped fixing blocks 1 is fixedly connected to the top of the arc plate.

[0010] As a further optimization of this utility model, the inner sides of the U-shaped fixing block one and the U-shaped fixing block two are provided with sliding grooves. A connecting rod is fixedly connected inside the sliding groove on the U-shaped fixing block two. A screw rod is rotatably connected to the outside of the connecting rod and is movably disposed inside the sliding groove on the U-shaped fixing block one. A nut is threadedly connected to one end of the screw rod, and a circular ring plate sleeved on the outside of the screw rod is abutted against the bottom of the nut.

[0011] As a further optimization of this utility model, the top of the U-shaped fixing block one is provided with two limiting grooves two, and the outer side of the annular piece is fixedly connected with a limiting block that cooperates with the two limiting grooves two.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves contacting the bottom of the twisted blade with a U-shaped fixing block one, then rotating a U-shaped fixing block two to contact the top of the twisted blade, then rotating the screw perpendicular to the connecting rod, inserting the ring plate and engaging the limiting block with the limiting groove two, and then tightening the nut to fix the U-shaped fixing block one and U-shaped fixing block two on the twisted blade. By repeating the above operation, the arc plate can be fixed to the bottom of the twisted blade. For arc-shaped bottoms or different barrel shapes, the conical surface of the arc plate can fit the contour of the barrel bottom, ensuring that there are no dead corners for stirring at the bottom. The arc plate is detachable and can be replaced as needed, adapting to multiple specifications of material barrels.

[0014] 2. This utility model involves coating the bottom of the twisted blade with tungsten carbide and the sidewall with ceramic coating, then sliding the fixed shaft and flat key into the connecting shaft, and finally inserting the threaded pin to fix the coated twisted blade onto the connecting shaft. This method is suitable for stirring in various scenarios and improves the practicality and durability of the blade. Attached Figure Description

Detailed Implementation

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, a novel twisted blade for a dual planetary power mixer includes a connecting shaft 1, which is the core connecting component of the device. The top end of the connecting shaft 1 is welded and fixed to the output shaft of a servo motor. Through the connection with the output shaft of the servo motor, the speed can be precisely controlled by the servo motor to meet different mixing needs and realize the automation and controllability of the mixing process. A limiting groove is opened inside the connecting shaft 1 to provide installation guidance and improve installation portability.

[0023] like Figure 1 , Figure 2As shown, a stirring mechanism 2 is provided at the bottom of the connecting shaft 1. The stirring mechanism 2 is the core actuator for material stirring. Its rotation drives the material movement. A threaded pin 5 is provided on the outside of the connecting shaft 1, which slides through the stirring mechanism 2. The threaded pin 5 is inserted into the limiting hole of the fixed shaft 202, and then the other end is tightened with an anti-loosening nut for fixation, thereby axially fixing the connecting shaft 1 and the stirring mechanism 2 and preventing the stirring mechanism 2 from falling off during stirring. The stirring mechanism 2 includes a fixed shaft 202, which is the core support and connection of the stirring mechanism 2. The top of the fixed shaft 202 is located inside the connecting shaft 1, so that the fixed shaft 202 can receive power and be positioned within the connecting shaft 1. A twisted blade 201 is fixedly connected to the bottom of the fixed shaft 202. The twisted blade 201 adopts a twisted structure, which can form an up-and-down convection stirring effect when rotating, improving the material mixing efficiency. A flat key 203 is fixedly connected to the outside of the fixed shaft 202. The flat key 203 serves as a circumferential... The key 203 serves to position and transmit power, preventing power loss caused by relative rotation between the fixed shaft 202 and the connecting shaft 1. The outer side of the key 203 abuts against the limiting groove at the bottom of the connecting shaft 1, limiting the circumferential displacement of the fixed shaft 202 and ensuring that power is stably transmitted from the connecting shaft 1 to the fixed shaft 202 through the key 203. The fixed shaft 202 has a limiting hole inside that mates with the threaded pin 5, allowing the threaded pin 5 to pass through the connecting shaft 1 and the fixed shaft 202, thus achieving axial fixation between the two. The side wall of the twisted blade 201 is provided with a ceramic coating 3, which has excellent high temperature resistance and corrosion resistance, protecting the side wall of the twisted blade 201 from damage by high-temperature or corrosive materials and extending the service life of the blade. The bottom side of the twisted blade 201 is provided with a tungsten carbide coating 6, which has high hardness and strong wear resistance, resisting direct friction between the bottom of the twisted blade 201 and the material, and is especially suitable for stirring materials containing particles, reducing blade wear.

[0024] like Figure 2 , Figure 3 , Figure 4As shown, the outer wall of the stirring mechanism 2 is provided with two fixing components 4. The fixing components 4 are symmetrically distributed, which can make the arc plate 7 evenly stressed and stably fixed on the twisted blade 201. The bottom of the fixing component 4 is provided with an arc plate 7, which can assist in stirring the material at the bottom of the conical bucket, prevent the material from accumulating at the bottom of the bucket, and improve the uniformity of stirring. The fixing component 4 includes two U-shaped fixing blocks 401, which correspond to the two sides of the twisted blade 201 respectively, providing stable support for the arc plate 7. The inner walls of the two U-shaped fixing blocks 401 abut against the bottom of the twisted blade 201, realizing the initial positioning of the U-shaped fixing blocks 401 and the twisted blade 201, ensuring the accurate installation position of the fixing component 4. U-shaped fixing blocks 402 are rotatably connected to one side of each U-shaped fixing block 402. The U-shaped fixing blocks 402 can rotate around the fixing rod, making it easy to open and close to wrap the top of the twisted blade 201 and clamp the twisted blade 201 from top to bottom. The bottom of the two U-shaped fixing blocks 401 are fixedly connected to the top of the arc plate 7. The U-shaped fixing blocks 401 and the arc plate 7 are integrated into one unit through the fixed connection. The inner sides of the U-shaped fixing blocks 401 and the U-shaped fixing blocks 402 are provided with sliding grooves 408. The sliding grooves 408 provide installation and movement space. A connecting rod 403 is fixedly connected inside the sliding grooves 408 on the U-shaped fixing blocks 402. The connecting rod 403 serves as a component connecting the sliding grooves 408 on both sides of the U-shaped fixing blocks 402 and also provides a rotation fulcrum.

[0025] like Figure 3 , Figure 4 As shown, a screw 404 is rotatably connected to the outside of the connecting rod 403, and is movably disposed inside a sliding groove 408 opened on the U-shaped fixing block 401. The screw 404 can rotate around the connecting rod 403 and can move within the sliding groove 408 of the U-shaped fixing block 401. A nut 405 is threadedly connected to one end of the screw 404. Through the threaded engagement between the nut 405 and the screw 404, tightening the nut 405 can generate axial pressure, so that the U-shaped fixing block 401 and the U-shaped fixing block 402 tightly clamp the twisted blade 201. The bottom of the nut 405 abuts against a ring sleeved on the outside of the screw 404. The ring plate 406 increases the contact area between the nut 405 and the U-shaped fixing block 401, preventing the nut 405 from directly pressing the U-shaped fixing block 401 and causing damage. At the same time, it transmits the locking force of the nut 405. The top of the U-shaped fixing block 401 has two limiting grooves, which provide engagement space. The ring plate 406 is externally fixedly connected to a limiting block 407 that cooperates with the two limiting grooves. After the limiting block 407 engages with the limiting grooves, it prevents the ring plate 406 from rotating with the nut 405, ensuring that the nut 405 does not slip during tightening and ensuring a stable locking effect.

[0026] It should be noted that, when using this new type of twisted blade for a dual planetary power mixer, first apply a tungsten carbide coating 3 to the bottom of the twisted blade 201 and a ceramic coating 6 to the side wall. Then, slide the fixed shaft 202 and the flat key 203 into the interior of the connecting shaft 1, and insert the threaded pin 5 to fix the coated twisted blade 201 onto the connecting shaft 1.

[0027] When it is necessary to stir the contents of the conical barrel, first, make U-shaped fixing block 401 contact the bottom of the twisted blade 201, then rotate U-shaped fixing block 402 so that it contacts the top of the twisted blade 201. Then, rotate screw 404 perpendicular to connecting rod 403 to insert ring plate 406. Then, limit block 407 engages with limit groove 2, and screw on nut 405 to fix U-shaped fixing block 401 and U-shaped fixing block 402 on twisted blade 201. Repeat the above operation to fix arc plate 7 to the bottom of twisted blade 201.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
