Description

Technical Field

[0001] This utility model relates to the field of composite material preparation technology, and in particular to an intelligent vertical vibration heating yarn spreading rod. Background Technology

[0002] Composite materials are materials with new properties formed by combining two or more materials with different properties through physical or chemical methods. They are usually composed of two parts: a matrix material and a reinforcing material. The reinforcing material is used to improve the strength and rigidity of the material, while the matrix material is used to bond the reinforcing materials together and provide overall structural integrity. Composite material (prepreg) production equipment requires a yarn spreading device to spread the carbon fibers and lay them flat to present a seamless fabric surface when producing unidirectional prepreg. Currently, yarn spreading devices are divided into several types according to their different functions, such as: fixed yarn spreading rod, fixed lifting yarn spreading rod, horizontal vibrating yarn spreading rod, horizontal lifting vibrating yarn spreading rod, and vertical vibrating yarn spreading rod.

[0003] Existing vertical vibrating yarn spreaders typically do not allow for adjustable vibration amplitude. This makes it difficult for the equipment to adapt to diverse process requirements when handling yarns of different thicknesses or materials, resulting in low processing efficiency and inconsistent yarn quality. Furthermore, while some yarn spreaders do allow for adjustable amplitude, they lack heating functionality. In processes requiring yarn preheating, this affects the yarn spreading effect and subsequent processing performance, ultimately reducing the overall product quality. Utility Model Content

[0004] To overcome the limitations of existing vertical vibration yarn spreading rods, which typically have non-adjustable amplitude vibration, making it difficult for the equipment to adapt to diverse process requirements when handling yarns of different thicknesses or materials, resulting in low processing efficiency and inconsistent yarn quality; furthermore, while some yarn spreading rods have adjustable amplitude, they lack heating functions, which affects the yarn spreading effect and subsequent processing performance in processes requiring yarn preheating, thus reducing the overall product quality. This utility model provides an intelligent vertical vibration heating yarn spreading rod.

[0005] The technical solution is as follows: An intelligent vertical vibration heating yarn spreading rod includes a wall panel and a support plate; the wall panel is equipped with two sets of wall panels, the inner side of the two sets of wall panels is provided with a heating pipe, the outer end of the heating pipe is fitted with a yarn spreading pipe, and the outer side of the two sets of wall panels is provided with an intelligent module. The upper end of the intelligent module is equipped with a servo motor, and the servo motor is installed with the input end of the intelligent module.

[0006] Furthermore, both sets of wall panels are equipped with support plates on their outer sides, and a frame is installed at the lower end of the support plate. The support plate is fixed to the wall panel through the frame.

[0007] Furthermore, the frame has an internal cavity to accommodate the smart module, which is located inside the frame and fixed to the support plate.

[0008] Furthermore, a fixing plate is installed at the output end of the intelligent module. The fixing plate is based on the fact that a heat insulation block is installed at one end of the intelligent module, and a support block is fixed on one side of the heat insulation block. Multiple sets of screws are provided on one side of the support block and the heat insulation block. The support block and the heat insulation block are fixed to the fixing plate by screws.

[0009] Furthermore, bolts are installed inside the support block, and the yarn spreading tube is fixed to the support block by bolts.

[0010] Furthermore, a screw is provided on one side of the heating tube, and the heating tube is fixed to one end of the yarn spreading tube by the screw.

[0011] Furthermore, a protective block is installed on the outer cylindrical surface of the output end of the heating tube, and a fastening nail is provided at the outer end of the protective block. The protective block is installed and set with the heating tube by the fastening nail.

[0012] Furthermore, a protective tube is installed below the guard block, with its lower end extending through the frame to the outer end.

[0013] The beneficial effects are: This utility model achieves stable heat supply to the yarn spreading tube by using a heating tube to heat the yarn spreading tube, so that the fiber bundle is heated evenly when passing through the yarn spreading tube, making it easier to spread. In addition, the heat can soften the sizing agent on the fiber surface, reduce the adhesion between fibers, and improve the uniformity and effect of yarn spreading.

[0014] By using a smart module connected to a servo motor to adjust the amplitude, it can adapt to diverse process requirements when handling yarns of different thicknesses or materials. Precise amplitude control ensures that the yarn is subjected to uniform force during unfolding, avoiding fiber damage or uneven unfolding caused by excessive or insufficient amplitude, thereby improving the overall quality of the product.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] The main characteristics of composite materials include high performance, designability, lightweight yet high strength, and multifunctionality. By rationally selecting and combining different materials, composite materials can achieve high performance that is difficult to achieve with single materials, such as high strength, high rigidity, high toughness, high temperature resistance, and corrosion resistance. Furthermore, the composition and structure of composite materials can be designed according to different application requirements to meet specific performance needs. Many composite materials maintain high strength while having low density, thus they are widely used in aerospace, automotive, and other fields to achieve lightweight design. In addition to mechanical properties, composite materials can also possess various functions such as thermal insulation, sound insulation, electromagnetic shielding, and self-sensing.

[0023] Composite materials can be classified according to the type of matrix material and reinforcing material. Based on the matrix material, composite materials can be divided into resin-based composites, metal-based composites, and ceramic-based composites. Resin-based composites use resin as the matrix, such as epoxy resin and polyester resin, and common examples include glass fiber reinforced plastics (GFRP) and carbon fiber reinforced plastics (CFRP). Metal-based composites use metal as the matrix, such as aluminum and titanium, and the reinforcing material can be ceramic particles or fibers; they are used in aerospace and high-performance automotive parts. Ceramic-based composites use ceramics as the matrix, such as alumina and silicon carbide, and the reinforcing material is usually carbon fiber or ceramic fiber; they feature high temperature resistance and high strength, and are used in high-temperature structural components.

[0024] Based on the reinforcing material, composite materials can be classified into fiber-reinforced composites, particle-reinforced composites, and laminated composites. Fiber-reinforced composites use fibrous materials such as glass fiber, carbon fiber, and aramid fiber as reinforcing materials, exhibiting high strength and high modulus, and are widely used in aerospace, automotive, and sporting goods industries. Particle-reinforced composites use granular materials such as ceramic particles and metal particles as reinforcing materials, improving the strength and wear resistance of the material, and are commonly used in metal-based and ceramic-based composites. Laminated composites use layered materials such as graphene and silicon carbide sheets as reinforcing materials, possessing good electrical conductivity, thermal conductivity, and mechanical properties, and are used in electronic devices and high-temperature structural components.

[0025] Composite materials have found wide application in many fields due to their excellent performance and designability. In aerospace, composite materials are used to manufacture aircraft wings, fuselages, tail fins, and other components, significantly reducing aircraft weight and improving fuel efficiency. They are also used in high-temperature engine components, such as turbine blades and combustion chambers, exhibiting high temperature resistance and high strength. In the automotive industry, composite materials are used to manufacture car body panels, bumpers, and other components, reducing vehicle weight and improving fuel economy and safety. High-performance racing car bodies and chassis often utilize carbon fiber composites, characterized by high strength and low weight. In sporting goods, composite materials are used to manufacture bicycle frames, wheels, and other components, reducing weight and improving riding performance. Golf club shafts also frequently use carbon fiber composites, characterized by high strength and high elastic modulus. In electronics, composite materials are used to manufacture packaging materials for electronic devices, possessing good electrical conductivity, thermal conductivity, and mechanical properties. They are also used to manufacture electromagnetic shielding materials, exhibiting excellent electromagnetic shielding performance. In the construction industry, composite materials are used to manufacture structural components such as beams, columns, and slabs, which can improve the durability and seismic performance of the structure. Glass fiber reinforced plastics are also commonly used in exterior wall panels, roof tiles, and other components of buildings, which have good weather resistance and aesthetics.

[0026] With continuous advancements in technology, the development trend of composite materials is characterized by high performance, multifunctionality, greenness, and intelligence. Through the research and development of new reinforcing and matrix materials, the strength, rigidity, and high-temperature resistance of composite materials will be further improved. Simultaneously, composite materials will possess multiple functions such as self-sensing, self-healing, and electromagnetic shielding. Furthermore, the development of biodegradable and recyclable composite materials will reduce environmental impact. Combined with smart materials technology, composite materials will be able to sense environmental changes and automatically adjust their performance, providing broader application prospects for future industrial development and technological progress.

[0027] In composite material production, the vertical vibration heated yarn spreader is a key piece of equipment used to uniformly spread fiber bundles (such as carbon fiber and glass fiber). Through high-frequency vertical vibration and heating, it effectively reduces fiber damage and improves the uniformity of fiber distribution, thereby enhancing the performance of the composite material. The design of this yarn spreader typically includes the following technical features: First, the yarn spreader generates vertical vibration through a high-frequency vibration device, causing the monofilaments in the fiber bundle to disperse under the vibration, thus achieving uniform fiber spreading. Second, the yarn spreader is equipped with a heating function, which can preheat the fibers and decompose the sizing agent on the fiber surface, further improving the spreading effect. In addition, some advanced yarn spreader designs allow for amplitude adjustment to accommodate fibers of different thicknesses and materials, improving the versatility and flexibility of the equipment. The application of the vertical vibration heated yarn spreader not only improves the production efficiency of composite materials but also significantly enhances the quality and performance of prepregs, making it a promising candidate for applications in aerospace, high-end industrial equipment, and other fields.

The wall panel 1 is equipped with two sets of wall panels 1. The inner side of the two sets of wall panels 1 is provided with a heating pipe 9. The outer end of the heating pipe 9 is fitted with a yarn spreading pipe 10. The outer side of the two sets of wall panels 1 is provided with an intelligent module 4. The upper end of the intelligent module 4 is equipped with a servo motor 5. The servo motor 5 is installed with the input end of the intelligent module 4.

The support plate is fixed to the wall panel 1 through the frame 3.

[0029] Please see Figures 2-4 The frame 3 has an internal cavity to accommodate the intelligent module 4. The intelligent module 4 is located inside the frame 3 and is fixed to the support plate 2. The output end of the intelligent module 4 is equipped with a fixing plate 6. The fixing plate 6 is equipped with a heat insulation block 7 at one end of the intelligent module 4. A support block 8 is fixed to one side of the heat insulation block 7. The support block 8 and the heat insulation block 7 are provided with multiple sets of screws on one side. The support block 8 and the heat insulation block 7 are threadedly fixed to the fixing plate 6 by screws. The support block 8 is provided with bolts inside. The yarn spreading tube 10 is threadedly fixed to the support block 8 by bolts.

[0030] Please see Figures 3-5 A screw is provided on one side of the heating tube 9. The heating tube 9 is fixed to one end of the yarn spreading tube 10 by the screw. A protective block 11 is installed on the outer cylindrical surface of the output end of the heating tube 9. A fastening nail is provided at the outer end of the protective block 11. The protective block 11 is installed to the heating tube 9 by the fastening nail. A protective tube 12 is installed below the protective block 11. The lower end of the protective tube 12 extends to the outer end through the frame 3.

[0031] When installing the yarn spreading rod, first install the frame 3, support plate 2, and intelligent module 4 onto the wall panel 1 in sequence. Next, connect and install the fixing plate 6, heat insulation pad, and support block 8 in sequence. After installing the support block 8, install the heating tube 9 onto the yarn spreading rod. Pass the heating tube 9 cable through the fixing plate 6, heat insulation pad, support block 8, and the protective tube 12 of the guard block 11, and fix each component. This ensures that the fixing plate 6, heat insulation pad, support block 8, heating tube 9, yarn spreading rod, heat insulation pad, support block 8, and fixing plate 6 form a set of components fixed to the intelligent modules 4 on both sides. After passing the heating tube 9 cable through the protective tube 12, fix the protective tube 12 onto the guard block 11. When the structure needs to be installed and run, connect the heating tube 9 cable to the servo motor 5 and the control system. The control system controls the heating tube 9 to generate heat, simultaneously driving both... The side servo motor 5 rotates in a forward direction. Under the feedback detection of the encoder of the servo motor 5, the control system drives the two servo motors 5 to run at the same speed, angle and acceleration, converting the same rotational motion of the servo motors 5 into the vertical up and down motion of the yarn spreading rod. When it is necessary to adjust its operation, firstly, the vibration point height of the yarn spreading rod is input into the control system. The control system controls the rotation of the two servo motors 5 to move the two ends of the yarn spreading rod synchronously to the specified height. Then, the amplitude and frequency of the vertical vibration of the yarn spreading rod are input into the control system. The control system calculates and converts it into the number of forward and reverse rotations of the servo motor 5 and the time required for the number of rotations. Then, it sends a command to the servo motor 5, and the servo motor 5 controls the yarn spreading rod to vibrate vertically at the specified height with a set frequency and amplitude, so as to realize the processing of yarn.
