[0049] The winding device 6 is installed on the mounting support 1, and the winding device 6 is installed in the output direction of the split networker 53.

[0050] By adding a wire guiding tube 52 between the third wire guiding roller 4 and the split networker 53, on the one hand, it is convenient to horizontally introduce the nylon 6 raw yarn into the split networker 53, increasing the stability of the wire compounding. And through the preheating treatment of the heating mechanism 54 before compounding, the winding compounding between the multi-profile composite nylon 6 wires is more stable. After compounding, they can be closely attached and maintain the compounded shape, increasing the quality and stability after the multi-wire compounding.

[0051] During use, the nylon 6 raw yarns after different modification treatments respectively enter the first wire guiding roller 2 and the second wire guiding roller 3 for drainage;

[0052] At least two groups of the drained raw yarns are combined through the third wire guiding roller 4;

[0053] After combination, through the traction of the wire guiding tube 52, relative horizontal transmission is achieved;

[0054] During the transmission process, through the heating treatment of the heating mechanism 54, the preheating treatment of the wire guiding tube 52 is achieved;

[0055] The preheated raw yarns are input into the input end of the split networker 53, and the split networker 53 performs fiber mixing and compounding on at least two groups of raw yarns to produce profiled composite nylon 6 fibers;

[0056] The produced profiled composite nylon 6 is output through the output end of the split networker 53 and then wound and collected on the winding device 6.

[0057] The composite box body 51 is made of a heat-insulating board with a thickness of 10 - 20 mm. The heat-insulating board is a rock wool composite heat-insulating board with a thickness of 12 mm. The composite box body 51 adopts a structure with a single-sided panel installed movably, and the connection is fixed by bolt connection, which is convenient for opening the composite box body 51, so as to facilitate the maintenance or repair of the inside of the composite box body 51 from the side.

[0058] Both ends of the wire guiding tube 52 are of an annular arc surface structure, and the output end of the wire guiding tube 52 penetrates through the composite box body 51 and extends into the composite box body 51, and the output end of the wire guiding tube 52 faces the input end of the split networker 53.

[0059] The wire guiding tube 52 adopts a rigid plastic structure, and the inner surface of the wire guiding tube 52 is polished smoothly, providing stable support for the passage of the raw yarns and reducing the frictional damage during the passage of the raw yarns.

The heating temperature inside the composite box body 51 is 55°C to 60°C, providing support for preheating the raw filaments inside the composite box body 51.

[0061] It further includes a drainage fan 543 and a circulation pipe 55. The drainage fan 543 is fixedly installed inside the mounting cover 541.

[0062] The output end of the circulation pipe 55 is connected to the input end of the mounting cover 541, and the input end of the circulation pipe 55 is installed in the output direction of the composite box body 51. The input end of the circulation pipe 55 is communicated with the inside of the composite box body 51. The drainage fan 543 drains the air heated by the electric heating wire 542, accelerating the preheating efficiency of the raw filaments and reducing the preheating time. Moreover, after the hot air circulates through the circulation pipe 55, the temperature inside the composite box body 51 can be kept constant, reducing heat consumption.

[0063] Among them, the circulation pipe 55 uses an existing heat-insulating pipe for circulating and draining air and can achieve heat insulation of the air, reducing heat loss.

[0064] The working principle of the preparation device for special-shaped composite polyamide 6 fibers provided by the present invention is as follows:

[0065] The polyamide 6 raw filaments after different modification treatments respectively enter the wire guiding and transmission of the first wire guiding roller 2 and the second wire guiding roller 3;

[0066] After transmission, at least two groups of raw filaments are combined by the third wire guiding roller 4;

[0067] After combination, through the traction of the wire guiding pipe 52, relative horizontal transmission is achieved;

[0068] During the transmission process, through the heating treatment of the heating mechanism 54, preheating treatment of the wire guiding pipe 52 is achieved;

[0069] The preheated raw filaments are input into the input end of the split-type networker 53. The split-type networker 53 performs fiber mixing and compounding on at least two groups of raw filaments to produce special-shaped composite polyamide 6 fibers;

[0070] The prepared special-shaped composite polyamide 6 is output through the output end of the split-type networker 53 and then wound and collected on the winding device 6.

[0071] Compared with the related technology, the preparation device of the special-shaped composite polyamide 6 fiber provided by the present invention has the following beneficial effects:

[0072] By adding a wire guiding tube 52 between the third wire guiding roller 4 and the split-type networker 53, on the one hand, it is convenient to horizontally introduce the raw wire into the split-type networker 53, increasing the stability of wire compounding. And through the preheating treatment of the heating mechanism 54 before compounding, the winding and compounding between multiple special-shaped composite polyamide 6 wires are more stable. After compounding, they can fit tightly and maintain the compounded shape, increasing the quality and stability after multi-wire compounding.

[0073] Second Embodiment:

[0074] Please refer to Figure 4 、 Figure 5 and Figure 6 Based on a preparation device of a special-shaped composite polyamide 6 fiber provided in the first embodiment of the present application, a second embodiment of the present application proposes another preparation device of a special-shaped composite polyamide 6 fiber. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0075] Specifically, the difference of the preparation device of the special-shaped composite polyamide 6 fiber provided in the second embodiment of the present application is that the preparation device of the special-shaped composite polyamide 6 fiber further includes a wire feeding mechanism 7. The wire feeding mechanism 7 includes a driving motor 71, a driving gear 72, a driven gear 73, a rotating frame 74 and a wire feeding head 75. The driving motor 71 is fixedly installed on the composite box body 51. The shaft end of the driving motor 71 is fixedly installed with a driving gear 72. The surface of the driving gear 72 is meshed and installed with a driven gear 73. The shaft end of the driven gear 73 is rotatably installed at the output end of the split-type networker 53. The driven gear 73 is fixedly installed with a rotating frame 74. The rotating frame 74 is rotatably installed with a wire feeding head 75.

[0076] By installing a wire feeding mechanism 7 between the output end of the split-type networker 53 and the winding device 6, the wire feeding mechanism facilitates the auxiliary drainage of the mixed and compounded polyamide 6 fiber, enabling the polyamide 6 fiber to be stably conveyed towards the surface of the winding device 6, avoiding the bending or large inclination of the wire during conveying, which may affect the safety of the winding of the polyamide 6 fiber, ensuring the stability of the winding of the polyamide 6 fiber after compounding, and being able to adaptively adjust the output direction of the polyamide 6 fiber according to different installation positions of the winding device 6, providing stable and reliable support for the winding of the polyamide 6 fiber.

[0077] When in use, the driving motor 71 is connected to an external power supply to provide a stable power source for the rotation adjustment of the driving gear 72. When the driving gear 72 rotates, it can drive the driven gear 73 to rotate. The driven gear 73 drives the rotating frame 74 to rotate. When the rotating frame 74 rotates, it drives the wire feeding head 75 to rotate synchronously, so that the wire feeding head 75 that can adaptively rotate can adapt to the rotation transmission at different positions, realizing the stable conveying and winding of the shaped polyamide 6 fiber after forming.

[0078] The wire feeding head 75 is made of rigid plastic and has a semi-circular ring structure at both ends. The inner surface is polished smoothly. The ring and smooth structure can provide a stable transmission effect for the profiled composite polyamide 6 fiber, and at the same time reduce the twisting deformation of the profiled composite polyamide 6 fiber.

[0079] The working principle of the preparation device for the profiled composite polyamide 6 fiber provided in this embodiment:

[0080] After the profiled composite polyamide 6 fiber is output by the split-type networker 53, the fiber passes through the wire feeding head 75 and is wound on the winding device 6.

[0081] After the fiber passes through the wire feeding head 75, the driving motor 71 is started. The driving gear 72 drives the driven gear 73 to rotate. The driven gear 73 drives the wire feeding head 75 to rotate through the rotating frame 74, so that the wire feeding head 75 rotates to the corresponding rotation direction for docking with the winding device 6 installed at different positions.

[0082] The beneficial effects of the preparation device for the profiled composite polyamide 6 fiber provided in this embodiment:

[0083] By installing a wire feeding mechanism 7 between the output end of the split-type networker 53 and the winding device 6, the wire feeding mechanism is convenient for auxiliary drainage of the mixed and composite polyamide 6 fiber, so that the polyamide 6 fiber can be stably conveyed towards the surface of the winding device 6, avoiding the bending or large inclination of the wire during conveying, which affects the safety of the winding of the polyamide 6 fiber, ensuring the stability of the winding of the polyamide 6 fiber after compounding, and being able to adaptively adjust the output direction of the polyamide 6 fiber according to the different installation positions of the winding device 6, providing stable and reliable support for the winding of the polyamide 6 fiber.

[0084] Optimization plan:

[0085] Furthermore, for the preparation device of the special-shaped composite nylon 6 fiber, an adjustment groove 751 is provided on the wire pay-off head 75. The device further includes an anti-backwinding mechanism 8, a telescopic member 81 and a telescopic clamp 82. The telescopic member 81 is fixedly installed on the wire pay-off head 75. The shaft end of the telescopic member 81 penetrates through the wire pay-off head 75 and extends into the adjustment groove 751. The shaft end of the telescopic member 81 is slidably connected to the wire pay-off head 75, and a telescopic clamp 82 is fixedly installed at the shaft end of the telescopic member 81. The telescopic clamp 82 is slidably installed on the wire pay-off head 75 through the adjustment groove 751.

[0086] By installing the anti-backwinding mechanism 8 on the wire pay-off head 75, when the winding and coiling of the special-shaped composite nylon 6 fiber are completed and a roll change is required, the anti-backwinding mechanism 8 can clamp the special-shaped composite nylon 6 fiber to maintain the stability of the special-shaped composite nylon 6 fiber after the roll change and prevent the fiber from backwinding and loosening, thus ensuring the stability of the winding and coiling of the special-shaped composite nylon 6 fiber.

[0087] The present invention also provides a method for preparing a special-shaped composite nylon 6 fiber, which includes the following steps:

[0088] S1, melting the nylon 6 raw material;
