Description
Technical Field
[0001] This invention relates to the technical field of carbon fiber composite material preparation equipment, and in particular to a low-loss, high-precision carbon fiber drawing and steering device. Background Technology
[0002] Carbon fiber, as a high-performance fiber material, possesses excellent properties such as lightweight, high strength, high modulus, and corrosion resistance, and is therefore widely used in many fields such as aerospace, automotive manufacturing, and sporting goods. With the continuous growth in demand for carbon fiber composite materials, its preparation technology is becoming increasingly crucial. Long-distance transport of carbon fibers is a vital step in the preparation process, but traditional drawing and steering equipment has many shortcomings.
[0003] In terms of drawing force, it is difficult to achieve stable and precise control, resulting in uneven stress on the carbon filaments, affecting their physical properties and the quality stability of subsequent composite materials. During the turning process, due to unreasonable structural design, the friction between the carbon filaments and the turning components is large, easily causing carbon filament wear and breakage, reducing production efficiency. In addition, the existing equipment has a complex structure, increasing manufacturing costs, making maintenance and operation difficult, and requiring high technical skills from operators. In high-end application fields with extremely high requirements for carbon filament quality, traditional equipment is even more unable to meet the needs. These problems seriously hinder the optimization of carbon fiber composite material preparation processes and industrial development, making the development of low-loss, high-precision carbon filament drawing and turning equipment an urgent priority. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to address the shortcomings of the existing technology by proposing a low-loss, high-precision carbon fiber drawing and steering device that improves the production quality and efficiency of carbon fiber composite materials and reduces production costs.
[0005] The technical problem to be solved by the present invention is achieved through the following technical solution: a low-loss, high-precision carbon wire drawing and steering device, characterized by: Includes a bottom support frame, frame stabilizing components, side support plates, direction adjustment plates, carbon wire drawing rollers, wire threading plates, and drawing transmission mechanisms. Bottom support frame: The bottom of the frame has multiple mounting holes, which are used to firmly connect it to the ground or other foundation platform with bolts and other connectors to ensure that the equipment will not shift during operation; Frame stabilizing components: The bottom support frame is fixed in place by bolts or welding to meet different installation requirements. When it needs to be connected to an external metal frame, welding can be used to achieve a secure connection, enhancing the stability of the equipment within the overall production system. Furthermore, the bottom support frame has pre-drilled threaded holes. When production requires raising the entire equipment, the height can be adjusted using a lifting device (such as a screw) that matches the threaded holes. During the lifting process, the frame stabilizing components can adjust their height within a certain range, and then use their unique locking structure to fix the entire equipment back to the new height position, ensuring stable operation at different heights and greatly improving the flexibility and adaptability of the equipment. Side support plate: The side is tilted at 45~70° to evenly arrange and separate carbon filaments of different levels, avoiding the problem of multiple carbon filaments getting tangled together during transmission; Bearing fixing component: It fits tightly with the side support plate. Through precision machining and installation process, the fixing bearing used to install the carbon wire drawing roller is accurately fixed to the side support plate, so that the carbon wire can maintain a stable movement state during drawing and turning. Direction Adjustment Plate: Working in conjunction with the adjustment fixing component, it precisely adjusts the direction of the carbon wire passing through the wire threading plate. The direction adjustment plate is designed with four sets of arc holes, each set of arc holes corresponding to a carbon wire drawing roller. The drawing force can be adjusted by adjusting the adjustment fixing component up and down along the arc holes on the direction adjustment plate. The arc-shaped holes on the direction adjustment plate, in conjunction with the aluminum profile adjustment and fixing parts, enable precise and flexible adjustment of the stretching force within a certain range; Carbon filament drawing roller: A layer of rubber strip is wrapped around a stainless steel roller. The rubber strip has moderate elasticity and excellent friction characteristics, providing more stable and gentle friction for the carbon filament. Wire threading plate: It plays a pre-treatment role before the carbon wire enters the drawing roller. The wire threading plate has multiple holes evenly distributed, and each hole is filled with a ceramic eye. The ceramic eye has a smooth outer surface. After the carbon wire is evenly arranged through these holes and ceramic eyes, it is placed above the carbon wire drawing roller, ensuring that the carbon wire can enter the drawing and turning stage in a stable and orderly state. The drawing drive mechanism provides a continuous and stable forward drawing force to drive the carbon wire through the entire drawing process in the equipment; the magnitude and speed of the drawing force are controlled by the drawing drive mechanism. The carbon wires are first evenly arranged through ceramic holes in the wire threading plate to ensure that each wire can enter the subsequent process independently and orderly. Then, the neatly arranged carbon wires enter the carbon wire drawing roller area. Driven by the drawing transmission mechanism, the carbon wires begin to rotate at the set speed and direction. Due to the moderate friction between the rubber strip on the carbon wire drawing roller and the carbon wire, the carbon wire is drawn forward under the action of friction. At the same time, according to the specific requirements of the production process for the drawing force, the operator can adjust the position and angle of the carbon wire drawing roller by adjusting the aluminum profile adjustment fixture on the direction adjustment plate along the arc hole, thereby precisely adjusting the contact pressure and friction between the carbon wire and the drawing roller, and achieving precise control of the drawing force. Under the action of the side inclined structure of the side support plate, the carbon wires of different levels are naturally separated, avoiding entanglement during the transmission process. After drawing, the carbon wires achieve smooth turning by means of the large diameter structure of the carbon wire drawing roller and the softness of the rubber strip.
[0006] The technical problem to be solved by the present invention can also be further achieved by the following technical solution: the side inclination angle of the side support plate is 60°.
[0007] The advantages of existing technologies compared to existing technologies are: 1. Achieving Precise Drawing Force Control: Through a unique design of the direction adjustment plate and aluminum profile adjustment fasteners, this invention successfully achieves precise adjustment of the drawing force over a wide range. Compared with traditional equipment, the accuracy of drawing force control is significantly improved, with errors controlled within an extremely small range, meeting the precise requirements of various complex production processes for carbon fiber drawing force. This ensures that the carbon fiber maintains a stable tension and stress state throughout the drawing process, improving the quality and precision of carbon fiber drawing and providing higher-quality raw materials for the subsequent preparation of carbon fiber composite materials.
[0008] 2. Effective Prevention of Carbon Wire Entanglement and Wear: The innovative inclined structure of the side support plate and the application of ceramic eyes on the wire-threading plate effectively solve the problems of carbon wire entanglement and wear during transmission by addressing different aspects. The inclined side structure allows the carbon wires to separate naturally, avoiding overlapping and entanglement, and ensuring the orderly transmission of carbon wires. The smooth surface and durable properties of the ceramic eyes reduce frictional loss of the carbon wires during passage through the wire-threading plate and turning. At the same time, the rubber strip design on the carbon wire drawing roller further reduces mechanical damage to the carbon wires during drawing and turning. These measures work together to significantly improve the quality of carbon wires, reduce the scrap rate caused by carbon wire damage, and improve production efficiency and product quality stability.
[0009] 3. Significantly Improved Equipment Adaptability and Flexibility: The height-adjustable design of the bottom support frame and the multi-dimensional adjustability of various components give the equipment of this invention extremely high adaptability and flexibility. Whether facing different production site requirements, different specifications of carbon fiber, or diverse production process needs, the equipment can quickly adapt through simple adjustments. This flexibility not only reduces the difficulty of installation and commissioning but also improves the equipment's versatility and reliability in different production environments, providing greater convenience and assurance for enterprise production.

Detailed Implementation
[0011] The specific technical solutions of the present invention are further described below. To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, and to facilitate a better understanding of the present invention by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments, and do not constitute a limitation on its rights. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0012] A low-loss, high-precision carbon wire drawing and steering device mainly includes a bottom support frame, frame stabilizing components, side support plates, direction adjustment plates, carbon wire drawing rollers, wire threading plates, and a drawing transmission mechanism.
[0013] 1. Bottom Support Frame: Constructed from high-strength steel, it boasts excellent structural strength and stability, providing a solid foundation for the entire equipment. Multiple mounting holes at the bottom of the frame allow for secure connection to the ground or other foundation platforms via bolts or other fasteners, ensuring the equipment remains stable during operation.
[0014] 1.1 Frame Stabilizing Component: A key component of the bottom support frame, it has multiple functions. Firstly, it can fix the bottom support frame in a designated position via bolts or welding to meet different installation requirements. When connecting to an external metal frame, welding can be used to achieve a secure connection, enhancing the stability of the equipment within the overall production system. Secondly, the bottom support frame has pre-drilled threaded holes. When production requires raising the entire equipment, the height can be adjusted using a lifting device (such as a screw) adapted to the threaded holes. During equipment raising, the frame stabilizing component can adjust its height within a certain range, and then, through its unique locking structure, it can re-secure the entire equipment at the new height, ensuring stable operation at different heights and greatly improving the equipment's flexibility and adaptability.
[0015] 2. Side Support Plate: Innovatively adopts a unique structural design with a 60° side inclination. This design plays an important role in the carbon filament transport process, naturally and effectively arranging and separating carbon filaments of different levels, avoiding the problem of multiple carbon filaments becoming entangled during transport, ensuring the uniformity and stability of carbon filament transport, and laying a good foundation for subsequent drawing and transfer operations.
[0016] 2.1 Bearing Fixing Components: These bearings, which are used to mount the carbon fiber drawing rollers, are precisely fixed to the side support plate through precise machining and installation processes, ensuring tight fit with the side support plate. This design guarantees the installation accuracy and stability of the bearings, providing reliable support for the smooth operation of the carbon fiber drawing rollers. It allows the carbon fiber to maintain a stable motion during drawing and turning processes, further improving the operational reliability of the equipment and the quality of carbon fiber processing.
[0017] The 3-direction adjustment plate, working in conjunction with the 3.1 aluminum profile adjustment fixing component, precisely adjusts the direction of the carbon wire passing through the 5-wire-threading-hole plate. The direction adjustment plate features four sets of arc-shaped holes, each corresponding to a 4-wire carbon wire drawing roller. During production, when a larger drawing force is required, the operator can adjust the 3.1 aluminum profile adjustment fixing component downwards along the arc-shaped holes on the direction adjustment plate. This adjustment changes the relative position and angle of the carbon wire drawing, increasing the contact pressure and friction between the carbon wire and the drawing roller, thus achieving a larger drawing force output. Conversely, when a smaller drawing force is required, adjusting the 3.1 aluminum profile adjustment fixing component upwards along the arc-shaped holes reduces the contact pressure and friction, resulting in a smaller drawing force. This adjustable design provides high flexibility and precision in drawing force control during production, allowing for real-time adjustments based on different carbon wire specifications and diverse production process requirements, significantly improving equipment adaptability and production efficiency. The ingenious combination of the arc-shaped holes on the direction adjustment plate and the aluminum profile adjustment fasteners enables precise and flexible adjustment of the drawing force within a certain range. This innovative design allows the equipment to quickly and accurately adjust the drawing force according to different production process requirements and carbon wire specifications, greatly improving the adaptability of the equipment and the controllability of the production process. This is one of the key innovations of this invention.
[0018] 4. Carbon Wire Drawing Roller: As one of the core components of the equipment, its structural design is ingenious. The body is made of stainless steel, providing excellent rigidity and durability. A special rubber strip is wound and coated around the stainless steel roller. This strip possesses moderate elasticity and excellent frictional properties. Compared to the stainless steel roller itself, the rubber strip provides a more stable and gentler frictional force to the carbon wire, ensuring sufficient traction during the drawing process while effectively reducing wear and loss of the carbon wire that could result from excessive friction.
[0019] With the synergistic effect of the three-way adjusting plates, the carbon fiber drawing roller can adjust the drawing force of different gradients according to actual production needs, meeting the requirements of various complex production processes. Simultaneously, due to the relatively soft material of the rubber strip, mechanical damage to the carbon fiber is greatly reduced during drawing and turning processes, significantly improving the quality and integrity of the carbon fiber. Furthermore, the carbon fiber drawing roller body adopts a large-diameter structural design. This design allows for a larger turning angle experienced by the carbon fiber during turning adjustments, effectively reducing bending stress and loss during the drawing process, further extending the service life of the carbon fiber, and improving production efficiency and product quality.
[0020] 5. Threading Perforation Plate: This plate plays a crucial pre-treatment role before the carbon wire enters the drafting roller. Multiple evenly distributed holes are present on the threading perforation plate, each containing a carefully placed ceramic eye. The ceramic eye has a smooth outer surface; its material properties not only give the turning section excellent wear resistance, extending its service life and effectively saving production costs, but its smooth surface also greatly reduces the frictional resistance of the carbon wire during operation, minimizing wear. After being evenly arranged through these holes and ceramic eyes, the carbon wire is placed above the carbon wire drafting roller, providing excellent initial conditions for the subsequent drafting and turning processes. This ensures that the carbon wire enters the drafting and turning stages in a stable and orderly manner, further improving the stability of the entire production process and product quality.
[0021] 6. Drawing Drive Mechanism: This is the core component of the equipment's power transmission. Its main function is to provide a continuous and stable forward drawing force to drive the carbon filament smoothly through the entire drawing process. The drawing drive mechanism employs advanced transmission technologies, such as motor drive combined with precision gear transmission or efficient belt drive, enabling precise control of the drawing force and speed according to production process requirements. Simultaneously, the connection and collaborative design between this mechanism and other components have been carefully optimized to ensure the stability and reliability of power transmission, providing strong and stable power support for the entire drawing and steering process, and guaranteeing efficient and stable operation of the equipment under various production conditions.
[0022] The carbon wires are first evenly arranged through ceramic eyelets on the wire-threading plate, ensuring that each wire enters the subsequent process independently and orderly. Then, the neatly arranged carbon wires enter the carbon wire drawing roller area. Driven by the drawing transmission mechanism, the carbon wires begin to rotate at a set speed and direction. Due to the moderate friction between the rubber strip on the carbon wire drawing roller and the carbon wire, the carbon wire is drawn forward under the action of friction. Simultaneously, according to the specific requirements of the production process for the drawing force, the operator can adjust the position and angle of the carbon wire drawing roller by adjusting the aluminum profile adjusting fastener on the direction adjusting plate along the arc hole, thereby precisely adjusting the contact pressure and friction between the carbon wire and the drawing roller, achieving precise control of the drawing force. With the side support plate tilted at 45~70° (optimal 60°), the carbon wires of different levels are naturally separated, avoiding entanglement during transport. After drawing, the carbon wires can achieve smooth turning thanks to the large diameter structure of the carbon wire drawing roller and the soft characteristics of the rubber strip. Throughout the process, the bottom support frame and its stabilizing components ensured the stable operation of the equipment, providing a solid and reliable foundation for the drawing and turning of the carbon wire, and guaranteeing the continuity and stability of the production process.
