[0002] Carbon fiber unwinding is a key process in the production of high-performance composite materials. Its core objective is to uniformly unwind the carbon fiber bundles in the prepreg to form a preform with controllable thickness and uniform fiber distribution. This process directly affects the mechanical properties and surface quality of composite products and plays an irreplaceable role in fields such as aerospace, rail transportation, and high-end sporting goods.

[0003] A search revealed that patent CN220555734U discloses a carbon fiber yarn spreading device, including a frame. A first release paper feeding mechanism is located below one end of the frame, and a second release paper feeding mechanism is located above the other end. Lower and upper layers of release paper are respectively placed within the first and second release paper feeding mechanisms. A hot-pressing roller is also mounted on the frame, with both the lower and upper release papers passing through it. Carbon fiber yarn is positioned between the upper and lower release papers. The device also includes a distribution roller for evenly distributing the carbon fiber yarn. The outer surface of the distribution roller is uniformly provided with annular wiring grooves to accommodate the carbon fiber yarn. The distribution roller is rotatably mounted on the frame. This carbon fiber yarn spreading device, through the distribution roller with annular wiring grooves on its outer surface, not only evenly distributes the carbon fiber yarn but also reduces wear on the carbon fiber yarn.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 A dust collection assembly includes a base 1 and a carbon fiber rope 7. A raw material box 9 is fixedly installed on the upper end of the base 1, and a dust cover 5 is fixedly installed on the side end of the raw material box 9. A finished product box 8 is fixedly installed on the end of the dust cover 5 away from the raw material box 9. A winding machine 2 is rotatably installed on the side end of the finished product box 8. Multiple supports 20 are arranged in an array between the dust cover 5 and the base 1, and the supports 20 serve to support the dust cover 5. A dust collection hood 11 for collecting floating dust is fixedly installed on the inner wall of the raw material box 9. When the power is turned on, the carbon fiber rope 7 enters the raw material box 9 under the traction of the winding machine 2. The extrusion shaft set in the raw material box 9 extrudes and unfolds the carbon fiber rope 7 to a suitable thickness. The dust collection hood 11 absorbs the carbon fiber particles generated during the extrusion and unfolding process, preventing the carbon fiber particles from adhering to the surface of the carbon fiber during the extrusion and unfolding process. The carbon fiber rope 7 is unrolled in the dust cover 5.

[0017] Please see Figures 1-3 A dust collection pipe 18 is fixedly installed on the side wall of the dust collection hood 11, and a diverter block 19 is fixedly installed at the upper end of the dust collection pipe 18. When the diverter block 19 is working, it will evenly distribute the negative pressure airflow into the dust collection hood 11, so that the carbon fiber particles in the extrusion and unfolding process will be evenly absorbed and collected by the dust collection hood 11.

[0018] Please see Figures 1-3An exhaust pipe 17 is fixedly installed at the end of the diverter block 19 away from the dust collection hood 11. An exhaust pump 16 is fixedly installed below the exhaust pipe 17. A filter box 4 is fixedly installed below the exhaust pump 16. When the carbon fiber rope 7 moves to the extrusion shaft set in the raw material box 9 for extrusion, the exhaust pump 16 is activated, so that the dust collection hood 11 sucks in and collects the carbon fiber particles in the extrusion and unfolding process. The carbon fiber particles are transferred to the exhaust pipe 17 through the dust collection pipe 18 and the diverter block 19. The carbon fiber particles are transferred to the filter box 4. The filter screen set in the filter box 4 filters and collects the carbon fiber particles, preventing workers from inhaling carbon fiber particles and affecting their health.

[0019] Please see Figures 1-3 Air inlets 12 are fixedly installed at the inlet and outlet of both the raw material box 9 and the finished product box 8. An air blowing pipe 15 is fixedly installed at the end of the air inlet 12 away from the dust collection hood 11. An air blowing pump 14 is fixedly installed at the lower end of the air blowing pipe 15. When the carbon fiber rope 7 enters the air inlet 12, the air inlet 12 blows out high-pressure clean air to isolate the floating dust entering the carbon fiber rope 7. The clean air is pumped in by the air blowing pump 14 and enters the air inlet 12 through the air blowing pipe 15, preventing floating dust in the outside air from entering the raw material box 9 and the finished product box 8, thereby avoiding the carbon fiber rope 7 from sticking to floating dust in the outside air.

[0020] Please see Figures 1-2 Multiple yarn spreading rollers 10 are installed at different positions on the inner wall of the dust cover 5, and carbon fiber rope 7 is wound on the outer wall of the yarn spreading roller 10. A drive motor 21 is fixedly installed on the side end of the yarn spreading roller 10 near the finished product box 8 of the dust cover 5. When the drive motor works, it will drive the yarn spreading roller 10 to rotate. The yarn spreading roller 10 causes the carbon fiber heated by the lamp holder 6 to be spread and thinned through the roller group, vibration and friction, so that the carbon fiber rope 7 is processed into the finished product of the required specifications.

[0021] Please see Figures 1-4A dust collection component and a carbon fiber spreading heating device are disclosed, comprising a lamp holder 6, which is fixedly installed at the upper and lower ends of a dust cover 5 near the finished product box 8. Each lamp holder 6 is equipped with multiple lamp tubes 13 for heating and spreading carbon fiber ropes 7. The lamp holders 6 at the upper and lower ends heat the upper and lower surfaces of the carbon fiber ropes 7 after they are compressed and spread, ensuring more uniform heating when the carbon fiber ropes 7 move to the lamp holder 6. Lamp covers 22 are fixedly installed on the inner wall of the dust cover 5 near the lamp tubes 13. The lamp tubes 13 emit infrared rays to the carbon fiber, which are then focused by the lamp covers 22 to heat the surface of the carbon fiber. A data cable 23 is fixedly installed at the control end of the lamp tubes 13. The end of the data cable away from the lamp tubes 13 is fixedly connected to a control box 3 for controlling the irradiation temperature of the lamp tubes 13. The control box 3 is fixedly installed on the side of the dust cover 5. The operator controls the control box 3, and power data is transmitted to the lamp holder 6 via the data cable 23. The lamp tubes 13 are activated to heat the compressed carbon fiber ropes 7, and the required process temperature is achieved by adjusting the power.

[0022] Working principle: When the carbon fiber rope 7 needs to be unwound and heated, the air pump 14 is started. The airflow is transmitted to the air outlet 12 through the air pipe 15. The air outlet 12 compresses and sprays out the gas to prevent dust from the parts of the finished product box 8 and the raw material box 9 that are in contact with the outside air. The carbon fiber rope 7 is initially unwound through the extrusion shaft set in the raw material box 9. The air pump 16 is started and the dust collection hood 11 starts to suck in the air to extract the carbon fiber particles generated in the extrusion and unwound process from the raw material box 9, so as to avoid the carbon fiber particles generated in the extrusion and unwound process of the carbon fiber rope 7 adhering to the surface of the carbon fiber and affecting subsequent processing. When the carbon fiber rope 7 is moved into the dust cover 5, the staff can start the control box 3 to adjust the data cable 23 to the appropriate power of the lamp tube 13. The lamp tubes 13 set at the upper and lower ends of the dust cover 5 can simultaneously heat the upper and lower surfaces of the unfolded carbon fiber rope 7 evenly, so as to avoid the carbon fiber rope 7 being affected by temperature during processing and transportation, which would affect the product quality.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
