Description

Technical Field

[0001] The present invention relates to the technical field of inorganic fiber dispersion, and particularly to a carbon fiber dispersing machine and a using method thereof. Background Art

[0002] In the modern industrial field, especially in the production process of carbon fiber composites, the dispersion of carbon fibers is a crucial link. Carbon fibers have excellent properties such as high strength, low density, and high modulus, and are widely used in many fields such as aerospace, automotive, and sports equipment. However, carbon fibers usually exist in the form of bundles or filaments, and their own high aspect ratio makes them prone to agglomeration when compounded with matrix materials (such as resins, plastics, etc.), resulting in uneven distribution of carbon fibers in the matrix, seriously affecting the performance of the final composite material.

[0003] Traditional carbon fiber dispersion methods mainly use simple stirring equipment or manual stirring methods, and these methods have many limitations. For example, simple stirring equipment often only uses a single stirring paddle, with low stirring efficiency, unable to fully break up and disperse carbon fibers, having poor adaptability to carbon fibers of different lengths, different contents, and matrix materials of different viscosities, and it is difficult to achieve uniform distribution of carbon fibers in the matrix. Although manual stirring can be adjusted to a certain extent according to the operator's experience, there are problems such as uneven stirring intensity, low efficiency, difficulty in large-scale production, and it cannot ensure the stability and consistency of product quality. At the same time, some existing carbon fiber dispersing machines cannot well solve the problem of carbon fiber agglomeration during the dispersion process, resulting in the mechanical properties and other properties of the final product unable to reach the ideal level. To solve the above problems, we have proposed a carbon fiber dispersing machine and a using method thereof. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a carbon fiber disperser and a usage method, having the following beneficial effects: 1.

[0017] 2. The disperser is equipped with a variable-speed drive device. By operating the control box, parameters such as the rotation speeds and operating times of the first dispersing motor, the second dispersing motor, and the lifting drive motor can be precisely set. This precise control ability enables users to flexibly adjust the working state of the equipment according to different carbon fiber materials and dispersing media, as well as specific processing requirements, so as to achieve the best dispersing effect. At the same time, the precise control of the lifting drive device also ensures that the dispersing drive device can accurately reach the working position, improving the stability and reliability of the equipment. During the processing, the carbon fiber disperser will generate a large amount of heat, especially the heat generated by friction and shear force when the stirring paddle and the scraper rotate at high speed.

[0018] 3. The disperser is designed with a cooling cavity surrounded between the inner wall and the outer wall of the side of the discharge cylinder. Through the circulating flow of the cooling medium, the heat generated by the dispersing and stirring is effectively absorbed, ensuring that the material properties and the equipment are not affected during long-term operation of the equipment. This not only improves the product quality but also extends the service life of the equipment.

[0019] 4. By operating the rotating rod to rotate the transmission gear, the disperser drives the lifting screw column to move up and down, changing the position of the discharge port cover plate, realizing the convenient discharge of materials. At the same time, a sieve is arranged in the discharge cylinder, which can accurately screen the dispersed carbon fiber to ensure that only the qualified carbon fiber falls onto the discharge inclined plate, improving the discharge efficiency and ensuring the quality and consistency of the product.

The second transmission gear 45 meshes with the first transmission gear 43.

[0032] Further, a method for using the carbon fiber dispersing machine is characterized in that: S1: Add an appropriate amount of cooling liquid (such as water, oil, etc.) into the cooling cavity 33 from the cooling medium inlet 32, and set the rotation speed, operation time, etc. of the first dispersion motor 21, the second dispersion motor 28, and the lifting drive motor 15 through the operation control box 4; S2: Open the sealing cover 10 and add carbon fiber and a dispersion medium into the dispersion cylinder 9; S3: Control the lifting drive motor 15 to reverse, so that the dispersion drive device 7 descends to the working position, enabling components such as the stirring paddle 38, the L-shaped scraper 34, the vertical scraper 36, and the bottom scraper 37 to work effectively; S4: Start the first dispersion motor 21 and the second dispersion motor 28, so that the carbon fiber dispersion rotating shaft 30 cooperates with the stirring paddle 38 and the scraper to disperse the carbon fiber; S5: The operation rotating rod 44 can be rotated for discharging. The material is screened by the screen 40, and the carbon fiber meeting the requirements falls onto the discharge inclined plate 41.

[0033] Working principle: When using this device, when the operation control box 4 receives a start signal, the lifting drive motor 15 starts to work. This motor is the power source for the entire lifting action. Its startup drives the actions of a series of subsequent components. The rotating shaft of the lifting drive motor 15 is connected to the gearbox 16. The gearbox 16 adjusts the rotation speed of the lifting drive motor 15 according to different application scenarios and operation requirements, and changes the torque to ensure the stability and safety of the lifting action. The power output of the gearbox 16 is transmitted to the threaded rod 18 inside the rotating sleeve 17. Due to the threaded connection between the threaded rod 18 and the lifting support rod 19, when the threaded rod 18 rotates, according to the principle of threaded transmission, the lifting platform 13 will achieve precise upward or downward movement along the direction of the metal connecting rod 2 under the guiding and limiting action of the limiting rod 12. The limiting rod 12 is movably inserted into the metal connecting rod 2 to ensure that the lifting platform 13 can only move in the vertical direction, avoiding platform deviation caused by external forces or unbalanced factors, and ensuring the accuracy and reliability of the lifting process. The lifting platform 13 is rigidly connected to the dispersion drive device 7 through the connecting plate 14, so it can drive the entire dispersion drive device 7 to rise or fall. In the initial stage of the equipment, the dispersion drive device 7 can be lifted to a higher position to facilitate opening the sealing cover 10 and adding carbon fiber raw materials and dispersion medium to the dispersion cylinder 9. During operation, it can be lowered to a suitable position to enable the dispersion stirring component to penetrate into the dispersion cylinder 9 and the discharge cylinder 8 to achieve efficient dispersion operation.

[0034] When the dispersion drive device 7 reaches the working position, the first dispersion motor 21 and the second dispersion motor 28 are started simultaneously. They are the core power sources for the carbon fiber dispersion and stirring actions, and cooperate to ensure the complex movements of multiple components. For the first dispersion motor 21, the driving gear 26 on its rotating shaft meshes with the transmission gear 24, transmitting the power to the first transmission wheel 23 on the rotating transmission seat 22. The first transmission wheel 23 drives the second transmission wheel on the carbon fiber dispersion rotating shaft 30 to rotate through the transmission belt 25, driving the carbon fiber dispersion rotating shaft 30 to rotate. The transmission belt 25 plays a role in buffering the starting and running impact vibrations of the motor, protecting the motor and other transmission components, and can also facilitate the adjustment of the transmission center distance, which is beneficial to the equipment layout and maintenance. At the same time, the driving gear 26 on the rotating shaft of the second dispersion motor 28 meshes with the third transmission gear 24 on the partition plate 20, transmitting the power to the auxiliary rotating shaft 29. The rotation of the auxiliary rotating shaft 29 drives the L-shaped scraper 34, the vertical scraper 36, and the bottom scraper 37 to rotate. These scrapers are distributed at different angles and positions in the discharge cylinder 8 to form an all-round stirring and scraping effect.

[0035] When the carbon fiber dispersion rotating shaft 30 rotates, the stirring paddle 38 at its lower end starts to stir the carbon fiber material in the dispersion cylinder 9. The scraper on the stirring paddle 38 is a key component designed for carbon fiber dispersion. Multiple scrapers are fixedly connected to the outer ends of the upper and lower sides in an annular and equally spaced manner, and the scrapers on the upper and lower sides are staggered. The staggered scrapers generate complex hydrodynamic effects during rotation. The upper-layer scrapers push the carbon fibers and dispersion medium above downward, and the lower-layer scrapers push the materials below upward, forming an up-and-down convection to achieve full mixing and stirring of the materials in the vertical direction. The distance between the scraper and the inner wall of the dispersion cylinder 9 is carefully designed to shear and disperse the carbon fiber material during the stirring process, and can also scrape off the attached materials on the cylinder wall to prevent the accumulation of materials to form dead zones, ensuring the uniform distribution of the materials in the dispersion cylinder 9. At the same time, the L-shaped scraper 34, the vertical scraper 36, and the bottom scraper 37 scrape and stir the carbon fiber material from different angles under the drive of the auxiliary rotating shaft 29. Specifically, the L-shaped scraper 34 forms an annular structure through the connecting ring 35. The vertical scraper 36 rotatably connected to the side of its vertical end can scrape off the materials on the cylinder wall, and the bottom scraper 37 on the lower side of the horizontal end can stir the bottom materials, enabling the materials to flow fully in the horizontal direction. The rotation of the scraper is combined with the stirring of the stirring paddle 38 to form a three-dimensional stirring and dispersion effect, dispersing the carbon fiber material from multiple dimensions, quickly breaking the carbon fiber aggregates, cutting the long fibers into short fibers, and uniformly dispersing them in the dispersion medium.

[0036] The dispersed carbon fiber material flows towards the bottom of the discharge cylinder 8 under the continuous stirring of the stirring paddle 38 and the scraper. When discharging is required, the rotating rod 44 is operated to rotate the second transmission gear 45, driving the first transmission gear 43 to rotate. Since the first transmission gear 43 is threadedly connected to the lifting threaded column 42, the rotation of the first transmission gear 43 drives the lifting threaded column 42 to move up and down, changing the position of the discharge port cover plate 39, and screening through the screen 40. Moreover, the discharge inclined plate 41 is inclined, and the gravity of the material is used to make the carbon fiber passing through the screen 40 flow naturally towards the second discharge port.

[0037] During the processing, the cooling medium enters the cooling cavity 33 through the cooling medium inlet 32. The cooling cavity 33 surrounds the inner and outer walls of the side of the discharge cylinder 8 to form an efficient heat exchange space. When the cooling medium flows through the cooling cavity 33, it absorbs the heat generated by the dispersion and stirring. Since the stirring paddle 38 and the scraper rotate at high speeds and generate a large amount of heat due to friction and shear force, especially when dealing with high-viscosity dispersion media, the heat will affect the performance and dispersion effect of the carbon fiber. Therefore, the cooling system is crucial. The cooling medium after absorbing the heat is discharged through the cooling medium outlet 31 to form a continuous cooling cycle, ensuring that the material performance and the equipment are not affected during the long-term operation of the equipment, and improving the product quality and equipment stability.

[0038] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
