Description

Technical Field

[0001] This invention relates to the field of carbon fiber mesh fabric processing technology, specifically to a carbon fiber mesh fabric production process and production equipment. Background Technology

[0002] Carbon fiber mesh, as a high-performance composite material, has become one of the core materials in fields such as building structure reinforcement, lightweight aerospace components, and high-end equipment manufacturing due to its high specific strength, strong corrosion resistance, and excellent aging resistance.

[0003] The publication number "CN112976602A" discloses a production process and equipment for carbon fiber mesh fabric. By optimizing the weaving process of carbon fiber mesh fabric, three straightening steel reeds are set up to evenly thread the yarn in layers, so that the warp yarns are evenly stressed during the weaving process, preventing local areas from being too loose or too tight. After weaving in the weaving equipment, the warp and weft yarns of the carbon fiber mesh fabric are firmly bonded using heated rollers. The bonding of the hot melt adhesive effectively solves the problem of warp yarn separation of the carbon fiber mesh.

[0004] However, the above-mentioned device still has the following problems during implementation: 1. Existing carbon fiber mesh production processes and equipment often use a single roller to support the filament roll, relying solely on the rotational speed of the unwinding roller to control the tension. As the diameter of the filament roll decreases during the unwinding process, problems such as filament loosening and stacking wrinkles can easily occur. Although some equipment has added tensioning rollers, it lacks an elastic adaptive structure and cannot dynamically adjust the tensioning force according to the real-time diameter of the filament roll, resulting in large fluctuations in filament tension, which directly affects the uniformity of resin adhesion in subsequent impregnation processes. 2. The pressure rollers of existing carbon fiber mesh impregnation equipment are mostly fixed installation structures, which can only be adapted to raw yarns of a specific width. When dealing with products of different specifications, it is necessary to change the pressure rollers or adjust the equipment layout, which is cumbersome and inefficient. 3. The current process of collecting carbon fiber mesh fabric after processing relies on manual sorting, which is not only inefficient, but also prone to errors in manual positioning, resulting in loose finished rolls with uneven sides, which increases the difficulty of subsequent storage and use. Summary of the Invention

[0005] The purpose of this invention is to provide a production process and equipment for carbon fiber mesh fabric to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A manufacturing process for carbon fiber mesh fabric includes the following steps: Step 1: Unwinding. Multiple rolls of carbon fiber filament are placed on the unwinding frame of the unwinding device. The carbon fiber filament is tensioned by the tensioning mechanism and guided by the guide rollers before being sent into the impregnation device. Step 2: Impregnation. The carbon fiber precursor is fully impregnated in the resin solution in the impregnation tank. At the same time, the resin solution circulates under the action of the resin solution circulation mechanism. The heating component controls the temperature of the resin solution at 45-55℃, and the impregnation time is 35-55 seconds. Step 3: Forming. The impregnated carbon fiber filaments enter the forming device and are formed by the cooperation of the lower forming roller and the upper forming roller. Under the action of the heating system and the pressurization system, the forming roller group forms a blank with a regular grid structure. Step 4: Winding. The cut carbon fiber mesh is wound into rolls by the winding rollers of the winding device. The drive motor adjusts the winding speed to match the previous process. The length counter measures the length of each roll. Winding is completed after the preset length is reached.

The unwinding roller is rotatably connected inside the unwinding frame. A rear elastic support component is matched and provided on the unwinding frame at a position below the unwinding roller.

[0009] As an optional solution for the production equipment of carbon fiber mesh fabric described in this invention, the elastic tensioning assembly includes a mounting plate, a connecting plate, and a tensioning frame. The mounting plate is symmetrically arranged inside the unwinding frame. One side of the connecting plate is slidably sleeved on the unwinding frame. The other side of the connecting plate is located above the mounting plate and is fixedly connected to it with a compression spring. The tensioning frame is symmetrically arranged on both sides of the connecting plate. The elastic force of the compression spring enables the tensioning frame to adhere and tighten the raw material on the unwinding roller, making it less prone to wrinkles during unwinding.

[0010] As an optional solution for the production equipment of carbon fiber mesh fabric according to the present invention, the impregnation device includes an impregnation tank and a pressure roller. The inner wall of the impregnation tank is provided with a heating structure. The resin liquid for impregnating carbon fiber filaments is placed in the impregnation tank. The heating structure is used to heat the resin liquid to a preset temperature. Two sets of sliding supports are slidably connected to both sides of the upper surface of the impregnation tank. The pressure roller is rotatably connected between the two sets of sliding supports.

[0011] As an optional solution for the production equipment of carbon fiber mesh fabric described in this invention, the impregnation tank has symmetrically opened grooves on both sides of its upper surface. A damping slider is fixedly connected to the bottom surface of the sliding bracket, and the damping slider is slidably connected inside the groove. A plate for mounting pressure rollers is symmetrically arranged on the top of the sliding bracket. In one embodiment, a motor is installed on the plate, and the output shaft of the motor is fixedly connected to the input end of the pressure roller through a coupling, which facilitates matching and adjustment according to the width of the impregnated fabric and allows for the installation of pressure rollers of different lengths.

[0012] As an optional embodiment of the carbon fiber mesh fabric production equipment described in this invention, the forming equipment includes a forming roller, a receiving roller, and a frame, both of which are provided with interlocking mesh-like ridges for pressing the impregnated carbon fiber filaments into mesh fabric blanks. A drying mechanism is provided on the inner side of the frame corresponding to the positions of the forming roller and the receiving roller, respectively. The forming roller is rotatably connected to the lower part of the frame, and the receiving roller is rotatably connected to the upper part of the frame and matched above the forming roller. A receiving tray is matched below the forming roller.

[0013] As an optional solution for the production equipment of carbon fiber mesh fabric according to the present invention, wherein: a cutting roller is provided on the top of the frame on one side of the receiving roller, the processed mesh fabric is cut into mesh fabric pieces of a preset length by the cutting roller and then received by the receiving tray, the receiving tray is slidably connected to the bottom surface of the frame, the bottom surface of the frame is symmetrically provided with grooves, the bottom surface of the receiving tray is fixedly connected to a sliding column corresponding to the groove, the sliding column is slidably connected in the groove, and a material straightening rod is provided on the upper surface of the receiving tray.

[0014] As an optional solution for the production equipment of carbon fiber mesh fabric described in this invention, a hollow rod is snapped into place at the lower position of the frame. A micro motor is provided on one side of the hollow rod. A lead screw is fixedly connected to the output shaft end of the micro motor. The lead screw is rotatably connected inside the hollow rod.

The straightening rod slides to position and arrange both sides of the fabric, so that the finished product is neat.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This carbon fiber mesh fabric production process and equipment utilizes a compression spring in an elastic tensioning component in conjunction with a tensioning frame. The tensioning force can adaptively adjust according to the real-time diameter of the raw filament roll: when the raw filament roll diameter is large, the compression spring is compressed, and the tensioning frame provides a larger initial tensioning force; as the raw filament roll diameter decreases, the spring rebounds, pushing the tensioning frame to continuously adhere to the raw filament, maintaining the raw filament tension stably within the optimal range. This structure reduces the wrinkle rate during raw filament unwinding, providing a smooth raw material base for subsequent processes. 2. The production process and equipment for carbon fiber mesh fabric, in which the trough of the impregnation tank cooperates with the damping slider, realizes stepless adjustment of the pressure roller position, adapts to the width range of multiple fabric models and matches different models of pressure rollers, the inner wall of the impregnation tank adopts a partitioned heating structure (such as multiple sets of independent electric heating tubes), combined with the stirring flow design of the adhesive circulation mechanism, so that the adhesive has uniform temperature, reduces the deviation of resin adhesion of the raw yarn, and significantly improves the consistency of product performance; 3. The production process and equipment for this carbon fiber mesh fabric include a drying mechanism integrated into the molding equipment (such as a hot air circulating oven), which can control the temperature of the blank at 80-90℃ while the mesh is being pressed, increasing the resin curing degree from 30% in traditional processes to 60%, effectively preventing deformation of the mesh structure; the lead screw drive of the material collection rod in the material collection stage, through the precise control of a micro motor, achieves relatively accurate positioning and improves the uniformity of material collection; 4. The production process and equipment for this carbon fiber mesh fabric are designed with a continuous process of "unwinding-impregnation-forming-receiving" as the core. The speed and parameters of each step are matched in a closed loop. Compared with the traditional segmented process (unwinding, impregnation, forming, drying and receiving are operated independently), the production cycle of a single roll of this process is shortened and the production efficiency is improved, which can meet the needs of large-scale industrial continuous production. 5. The production process and equipment for carbon fiber mesh cloth integrate each process unit on the same substrate, with a compact structure and small footprint; it has a high degree of automation, and manual intervention is only required for raw material loading, parameter setting and finished product transfer, with a low operating threshold, and is suitable for large-scale industrial production.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-9 The present invention provides a technical solution: Example 1, please refer to Figures 1 to 9 This invention discloses a production process for carbon fiber mesh fabric, comprising the following steps: Step 1: Unwinding. Multiple rolls of carbon fiber filament are placed on the unwinding frame of the unwinding device. The carbon fiber filament is tensioned by the tensioning mechanism and guided by the guide rollers before being sent into the impregnation device. Step 2: Impregnation. The carbon fiber precursor is fully impregnated in the resin solution in the impregnation tank. At the same time, the resin solution circulates under the action of the resin solution circulation mechanism. The heating component controls the temperature of the resin solution at 45-55℃, and the impregnation time is 35-55 seconds. Step 3: Forming. The impregnated carbon fiber filaments enter the forming device and are formed by the cooperation of the lower forming roller and the upper forming roller. Under the action of the heating system and the pressurization system, the forming roller group forms a blank with a regular grid structure. Step 4: Winding. The cut carbon fiber mesh is wound into rolls by the winding rollers of the winding device. The drive motor adjusts the winding speed to match the previous process. The length counter measures the length of each roll. Winding is completed after the preset length is reached.

[0020] In this embodiment, the continuous process design of "unwinding, impregnation, forming, and collecting" is the core. The speed and parameters of each step are matched in a closed loop. The unwinding speed is linked in real time with the subsequent impregnation and forming speed through a variable frequency motor to avoid the accumulation or stretching of the raw yarn. The impregnation time of 35-55 seconds is precisely matched with the adhesive temperature of 45-55℃, which ensures that the raw yarn is fully impregnated without affecting the production cycle. Forming and drying are carried out simultaneously, saving the time of a separate curing process.

[0021] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 9 This invention provides a carbon fiber mesh fabric production equipment, which can be used to realize the above-mentioned carbon fiber mesh fabric production process. The carbon fiber mesh fabric production equipment includes a substrate 1, and an unwinding device 2, an impregnation device 3, a forming device 4, and a winding device 5 arranged on one side of the upper surface of the substrate 1. Multiple sets of equipment are used in conjunction to process and produce carbon fiber mesh fabric. The substrate 1 serves as the mounting base, ensuring that the unwinding device 2, the impregnation device 3, the forming device 4, and the winding device 5 are arranged in a straight line along the material conveying direction, realizing a smooth transition of carbon fiber filaments or blanks. All drive motors (unwinding drive motor 6, pressure roller motor, and winding drive motor) are linked by a PLC controller (not shown in the figure, integrated in the control box) to ensure speed matching of each process, avoiding stretching, accumulation, or wrinkling of filaments or blanks, forming a closed-loop production process of "material supply, processing, and storage". The unwinding device 2 includes an unwinding frame 201 and an unwinding roller 202. A drive motor 6 is provided on one side of the unwinding frame 201. The output shaft end of the drive motor 6 is fixedly connected to one end of the unwinding roller 202. The unwinding roller 202 is rotatably connected inside the unwinding frame 201. A rear elastic support component 7 is matched and provided on the unwinding frame 201 at a position below the unwinding roller 202. The elastic tensioning assembly 7 includes a mounting plate 701, a connecting plate 702, and a tensioning bracket 703. The mounting plate 701 is symmetrically arranged inside the unwinding frame 201. One side of the connecting plate 702 is slidably sleeved on the unwinding frame 201, and the other side of the connecting plate 702 is located above the mounting plate 701 and is fixedly connected to it by a compression spring 8. The tensioning bracket 703 is symmetrically arranged on both sides of the connecting plate 702. The elastic force of the compression spring 8 allows the tensioning bracket 703 to exert force on the unwinding roller 202. The raw materials are bonded and tightened, making it less prone to wrinkles during unwinding. As the diameter of the raw yarn roll gradually decreases during unwinding, the compression spring 8 of the elastic tensioning component 7 releases its elastic force, pushing the connecting plate 702 to slide upward along the column of the unwinding frame 201. The connecting plate 702 drives the arc-shaped tensioning frames 703 on both sides to move upward synchronously, so that the rubber anti-slip layer on the surface of the tensioning frame 703 always adheres to the outer surface of the raw yarn roll, providing tension force to counteract the loosening tendency of the raw yarn due to the decrease in diameter and maintain the stability of the raw yarn tension. The impregnation equipment 3 includes an impregnation tank 301 and a pressure roller 302. The inner wall of the impregnation tank 301 is provided with a heating structure. The resin liquid for impregnating carbon fiber precursor is placed in the impregnation tank 301. The heating structure is used to heat the resin liquid to a preset temperature. Two sets of sliding supports 9 are slidably connected on both sides of the upper surface of the impregnation tank 301. The pressure roller 302 is rotatably connected between the two sets of sliding supports 9. The upper surface of the impregnation tank 301 is symmetrically provided with grooves 10 on both sides. The bottom surface of the sliding bracket 9 is fixedly connected with a damping slider 11, which is slidably connected inside the groove 10. The top of the sliding bracket 9 is symmetrically provided with plates 12 for mounting the pressure roller 302. One type of plate 12 is provided with a motor. The output shaft of the motor is fixedly connected to the input end of the pressure roller 302 through a coupling, which facilitates matching and adjustment according to the width of the impregnated fabric. Pressure rollers 302 of different lengths are installed. The wear-resistant rubber layer on the surface of the pressure roller 302 presses the raw yarn into the adhesive liquid, so that the raw yarn is completely immersed in the adhesive liquid. The path length of the raw yarn from entering the adhesive liquid to leaving the adhesive liquid is fixed, ensuring that the contact time between the raw yarn and the adhesive liquid is precise and controllable, and the final resin adhesion of the raw yarn is stable. The molding equipment 4 includes a molding roller 401, a take-up roller 402, and a frame 403. Both are equipped with interlocking mesh-like ridges for pressing the impregnated carbon fiber filaments into a mesh fabric blank. Drying mechanisms are provided on the inner side of the frame 403, corresponding to the positions of the molding roller 401 and the take-up roller 402. The molding roller 401 is rotatably connected to the lower part of the frame 403, and the take-up roller 402 is rotatably connected to the upper part of the frame 403 and is positioned above the molding roller 401. After the mesh blank passes through the space between the molding roller 401 and the take-up roller 402, the hot air circulation nozzles (two on the top and two on the bottom, symmetrically distributed) on the inner side of the frame 403 are activated, spraying hot air at 60-70°C. The hot air acts directly on the upper and lower surfaces of the blank. By controlling the distance (100mm) between the nozzle and the blank and the hot air temperature, the resin solvent on the surface of the blank evaporates quickly, increasing the degree of resin curing and preventing mesh deformation during subsequent cutting and conveying.

[0022] A receiving tray 13 is matched and positioned below the forming roller 401. A cutting roller 14 is positioned on the top of the frame 403, next to the receiving roller 402. The processed mesh fabric is cut into mesh fabric pieces of a preset length by the cutting roller 14 and then received by the receiving tray 13. The receiving tray 13 is slidably connected to the bottom surface of the frame 403. A groove 15 is symmetrically opened on the bottom surface of the frame 403. A sliding column 16 is fixedly connected to the bottom surface of the receiving tray 13 corresponding to the groove 15. The sliding column 16 is slidably connected in the groove 15. A straightening rod 17 is provided on the upper surface of the receiving tray 13. The cured mesh blank is pulled to the cutting roller 14 by the receiving roller 402. The annular carbide blade on the surface of the cutting roller 14 rotates with the roller (the rotation speed is synchronized with the blank conveying speed) to perform transverse cutting on the blank. The PLC controller controls the cutting roller 14 to stop rotating when the length reaches the preset value, based on the blank length data fed back by the length counter, to complete the fixed-length cutting. The blank is then transferred together with the finished product for centralized processing.

[0023] A hollow rod 18 is snapped into place at the bottom of the frame 403. A micro motor 19 is mounted on one side of each hollow rod 18. A lead screw 20 is fixedly connected to the output shaft of each micro motor 19, and the lead screw 20 is rotatably connected inside the hollow rod 18. Threaded sleeves 21 are fixedly connected to both ends of the material-aligning rod 17, and the threaded sleeves 21 are fitted onto the outer surface of the lead screw 20. After cutting, the fabric is fed into the receiving tray 13. The material-aligning rod 17 slides to position and tidy the two sides of the fabric, ensuring a neat finished product. The cut mesh fabric (width set according to requirements) falls vertically into the receiving tray 13. At this time, the PLC... The controller starts the micro motor 19, which drives the lead screw 20 inside the hollow rod 18 to rotate. The lead screw 20 drives the threaded sleeve 21 to move along the axial direction of the lead screw 20 through the threaded transmission. The threaded sleeve 21 pulls the material-aligning rod 17 (made of aluminum alloy with a rubber sleeve on the surface) to slide along the length of the receiving tray 13. The material-aligning rod 17 has a preset sliding stroke according to the width of the finished product, and pushes and positions the two sides of the finished product to ensure that the side alignment error of the finished product in the tray is small and to avoid the finished products from being stacked loosely.

[0024] Working Principle: The substrate 1 serves as the mounting base, ensuring that the unwinding equipment 2, impregnation equipment 3, forming equipment 4, and rewinding equipment 5 are arranged in a straight line along the material conveying direction, achieving a smooth transition between carbon fiber filaments and blanks. All drive motors (unwinding drive motor 6, pressure roller motor, and rewinding drive motor) are synchronized in speed via a PLC controller (not shown in the diagram, integrated into the control box), ensuring speed matching between each process and preventing stretching, accumulation, or wrinkling of the filaments or blanks, forming a "feed-processing-storage" process. The closed-loop production process uses the elastic force of the compression spring 8 to enable the tensioning frame 703 to adhere to and tighten the raw material on the unwinding roller 202, making it less prone to wrinkles during unwinding. As the diameter of the raw yarn roll gradually decreases during unwinding, the compression spring 8 of the elastic tensioning component 7 releases its elastic force, pushing the connecting plate 702 to slide upward along the column of the unwinding frame 201. The connecting plate 702 drives the arc-shaped tensioning frames 703 on both sides to move upward synchronously, so that the rubber anti-slip layer on the surface of the tensioning frame 703 always adheres to the outer surface of the raw yarn roll, providing tension force to counteract the loosening tendency of the raw yarn due to the decrease in diameter and maintain the stability of the raw yarn tension. The impregnation tank 301 is easily adjustable to match the width of the impregnated fabric. Pressure rollers 302 of varying lengths are installed, and the wear-resistant rubber layer on the surface of the rollers 302 presses the raw yarn into the adhesive solution, ensuring complete immersion. The path length of the raw yarn from entering to leaving the adhesive solution is fixed, ensuring precise and controllable contact time between the yarn and the adhesive solution, resulting in stable resin adhesion. After the mesh blank passes between the forming roller 401 and the take-up roller 402, the hot air circulation nozzles (two on each side, symmetrically distributed) inside the frame 403 are activated, spraying hot air at 60-70℃. The hot air directly acts on the upper and lower surfaces of the blank. By controlling the distance between the nozzles and the blank (100mm) and the hot air temperature, the resin solvent on the blank surface evaporates quickly, increasing the resin curing degree and preventing mesh deformation during subsequent cutting and conveying. The cured mesh blank is then pulled by the take-up roller 402 to the cutting roller 14. The annular carbide blades on the surface rotate with the roller (the rotation speed is synchronized with the billet conveying speed) to cut the billet laterally. The PLC controller controls the cutting roller 14 to stop rotating when the length reaches the preset value, based on the billet length data fed back by the length counter, to complete the fixed-length cutting. The cut billet is then transferred together with the finished product for centralized processing. The cut mesh fabric finished product (width set according to requirements) falls vertically into the receiving tray 13. At this time, the PLC controller starts the micro motor 19, which drives the lead screw 20 inside the hollow rod 18 to rotate. The lead screw 20 drives the threaded sleeve 21 to move along the axial direction of the lead screw 20 through the threaded transmission. The threaded sleeve 21 pulls the material-aligning rod 17 (made of aluminum alloy, with a rubber sleeve on the surface) to slide along the length direction of the receiving tray 13. The material-aligning rod 17 slides according to the preset sliding stroke of the finished product width, pushing and positioning the two sides of the finished product to ensure that the side alignment error of the finished product in the tray is small and to avoid the finished product from being stacked loosely.
