The carbon fiber filaments pass through the front guide device 2, the front dispersing and combing device 5, the humidification box 4, the rear dispersing and combing device 6 and the rear guide device 3 in sequence.

[0041] The application also discloses that the sprayed liquid is preferably a mixture of antistatic liquid, water and silicone oil.

[0042] Furthermore, if Figure 1 As shown, the front dispersing combing device 5 and the rear dispersing combing device 6 both include a combing base 51 connected to the frame 1, combing support frames 52 arranged at both ends of the combing base 51, a transverse combing rod 53 inserted between the two combing support frames 52, and a vertical combing rod 54 inserted on the combing base 51 and located on one side of the transverse combing rod 53; a plurality of transverse combing rods 53 and a plurality of vertical combing rods 54 are correspondingly cross-arranged to form dispersing combing holes 55, and the dispersing combing holes 55 are used for allowing carbon fiber filaments to pass through.

[0043] The front dispersing combing device 5 and the rear dispersing combing device 6 of the present application are connected to the frame 1 through the combing base 51 and supported by the combing support frame 52, thereby ensuring the stability and structural firmness of the front dispersing combing device 5 and the rear dispersing combing device 6; the cross-setting of the transverse combing rod 53 and the vertical combing rod 54 forms a plurality of dispersing combing holes 55, and each carbon fiber filament passes through the dispersing combing hole 55 individually, which not only improves the dispersing effect of the carbon fiber filaments, but also provides a uniform passing path for the carbon fiber filaments through the dispersing combing holes 55, thereby effectively improving the dispersing and combing quality of the carbon fiber filaments, and ensuring the uniformity of the carbon fiber filaments and the consistency of the products after being webbed.

[0044] Furthermore, if Figure 1 As shown, the transverse combing rods 53 are arranged in an array along the length direction of the combing support frame 52, and the vertical combing rods 54 are arranged in an array along the length direction of the combing base 51.

[0045] In the present application, the transverse combing rods 53 are arranged in an array along the length direction of the combing support frame 52, and the vertical combing rods 54 are arranged in an array along the length direction of the combing base 51 to form a plurality of evenly arranged dispersed combing holes 55.

Both sides of the box body 41 are respectively provided with conveying holes 43 for connecting the interior and exterior spaces of the box body 41; the two conveying holes 43 are respectively arranged corresponding to the front dispersing combing device 5 and the rear dispersing combing device 6 and are used for allowing the carbon fiber filaments to pass through.

[0047] The present application realizes an effective space for wet pretreatment of carbon fiber filaments by setting up a box body 41 and installing a humidifying cover 42; the conveying holes 43 on both sides of the box body 41 not only provide a channel for the carbon fiber filaments, ensuring that the carbon fiber filaments can smoothly pass through the front dispersing and combing device 5 and the rear dispersing and combing device 6, but also further enhances the stability of the carbon fiber filaments during the wet pretreatment process and improves the efficiency of the pretreatment process.

[0048] More specifically, if Figure 2 As shown, the humidifying cover 42 includes a humidifying cover frame 421 and a condensing inclined top cover 422 disposed on the humidifying cover frame 421 .

[0049] The humidifying cover 42 of the present application is composed of a humidifying cover frame 421 and a condensation inclined top cover 422. The inclined design of the condensation inclined top cover 422 facilitates the flow of the condensed water of the medicine to the bottom of the box 41, which helps to collect and discharge the condensed water of the medicine, and prevents the condensed water of the medicine from dripping directly onto the carbon fiber filaments, thereby ensuring the uniform wetting of the carbon fiber filaments during the wet pretreatment process and improving the quality and efficiency of the wet pretreatment.

[0050] In addition, if Figures 2 to 4 As shown, the humidifying spray device 7 includes a humidifier 71, a treatment solution delivery pipeline 72 for connecting the humidifier 71 and the inside of the humidification box 4, a condensed water return pipeline 73 connecting the bottom of the humidification box 4 and the humidifier 71, and a spray pipe 74 inserted in the humidification box 4 and connected to the treatment solution delivery pipeline 72.

At the same time, the setting of the condensed water return pipeline 73 effectively recovers the condensed water of the solution, reducing resource waste. The setting of the spray tube 74 ensures that the humidifying solution can be evenly sprayed on the carbon fiber yarn, thereby improving the uniformity and efficiency of the wet pretreatment, ensuring the softness and cohesion of the carbon fiber yarn, providing ideal wetting conditions for the subsequent web-forming process, and improving the quality and efficiency of the entire pretreatment process.

[0052] And, if Figure 3 As shown, the spray pipe 74 includes a spray pipe body 741 and atomizing nozzles 742 arranged in an array along the length direction of the spray pipe body 741 .

[0053] The spray tube 74 of the present application is composed of a spray tube body 741 and atomizing nozzles 742 arranged in an array along the length direction of the spray tube body 741.

[0055] The humidifier 71 of the present application is preferably an ultrasonic humidifier. The ultrasonic vibration technology of the ultrasonic humidifier can convert the treated solution into extremely fine atomized particles. This atomization method not only improves the humidification efficiency, but also ensures the uniform distribution and penetration of the solution inside the humidification box 4, thereby achieving uniform wetting pretreatment of the carbon fiber filaments; the use of an ultrasonic humidifier reduces the waste of solutions and improves the energy efficiency of the humidification process. In addition, since the atomized particles produced by the ultrasonic humidifier are fine, they can better adhere to the surface of the carbon fiber filaments, thereby enhancing the wetting effect and improving the softness and cohesion of the carbon fiber filaments.

[0056] Furthermore, if Figure 4 As shown, the front guide device 2 and the rear guide device 3 both include a guide support frame 21 arranged on the frame 1, a guide upper roller 22 arranged between the two guide support frames 21 and movably connected to the two guide support frames 21, and a guide lower roller 23 arranged below the guide upper roller 22; a guide space 24 is formed between the guide support frame 21 and the guide upper roller 22 and the guide lower roller 23 to allow the carbon fiber filaments to pass through.

[0057] The front guide device 2 and the rear guide device 3 of the present application effectively form a guide space 24 for the carbon fiber filaments to pass through through a combination of a guide support frame 21, an upper guide roller 22 movably connected to the guide support frame 21, and a lower guide roller 23 located below the upper guide roller 22; this structure not only ensures the stable guidance of the carbon fiber filaments during the wetting pretreatment process through the humidification box 4, but also realizes the precise control of the movement of the carbon fiber filaments, thereby improving the dispersion and combing quality of the carbon fiber filaments; the guide space 24 provides an orderly channel for the carbon fiber filaments, which helps to guide and move the carbon fiber filaments and reduce the friction and static electricity between the carbon fiber filaments.

[0058] Specifically, Figure 4 As shown, a quick slot 211 is provided at the end of the guide support frame 21, and the quick slot 211 is used for movably inserting the end of the guide upper roller 22 so that the guide upper roller 22 and the guide support frame 21 are detachably connected.

[0059] The quick slot 211 at the end of the guide support frame 21 of the present application is used for the movable insertion of the end of the guide upper roller 22, thereby realizing a detachable connection between the guide upper roller 22 and the guide support frame 21; this design provides the convenience of quick installation and disassembly, and is easy to maintain and replace the guide upper roller 22, thereby improving the maintenance efficiency and flexibility of the equipment; at the same time, the use of the quick slot 211 also simplifies the assembly and disassembly process of the entire front guide device 2 and the rear guide device 3, facilitates the guiding and installation of carbon fiber filaments, helps to reduce downtime in production, and ensures the continuity and stability of the production process.

[0062] The front dispersing and combing device 5 and the rear dispersing and combing device 6 are connected to the frame 1 through the combing base 51 and supported by the combing support frame 52, thereby ensuring the stability and structural firmness of the front dispersing and combing device 5 and the rear dispersing and combing device 6; the cross arrangement of the transverse combing rod 53 and the vertical combing rod 54 forms a plurality of dispersing and combing holes 55, and each carbon fiber filament passes through the dispersing and combing hole 55 individually, which not only improves the dispersing effect of the carbon fiber filaments, but also provides a uniform passing path for the carbon fiber filaments through the dispersing and combing holes 55, thereby effectively improving the dispersibility and combing quality of the carbon fiber filaments, and ensuring the uniformity of the carbon fiber filaments and the consistency of the products after being formed into a web;
