One side of each arc-shaped plate 814 close to the semi-finished cable 2 is connected by bolts with a scraping plate 815. The outside of each scraping plate 815 contacts the outside of the semi-finished cable 2. The positions of the three scraping plates 815 are staggered with each other;An annular seat 816 is arranged outside the semi-finished cable 2.

[0021] Specifically, start the motor 803. The motor 803 drives the toothed ring 805 meshing with the gear 804 to rotate, so that the twisting disc 5 gradually winds the three polymer hoses 6 around the outside of the semi-finished cable 2 during rotation. The polymer hoses 6 contain oil dry powder fire extinguishing agent and pressurized carbon dioxide. During the process of the semi-finished cable 2 being conveyed from the wire lead machine 3 to the bunching machine 7, start the pump 810. The pump 810 pumps the water conveyed into the storage bottle 807 through the infusion pipe 808 into the spray nozzle 809 and sprays it out, making the surface of the semi-finished cable 2 wet. Under the elastic force of the spring 813, the movable rod 811 presses the arc-shaped plate 814 tightly against the surface of the semi-finished cable 2, so that the scraper 815 wipes off the dirt on the surface of the semi-finished cable 2. The glue storage tank 822 conveys the stored glue to the glue storage box 818 through the conveying hose 823, so that the glue can flow into the space between the spacer bars 820 through the fine holes 819. Under the elastic force of the elastic reed pieces 821, the spacer bars 820 are tightly attached to the surface of the semi-finished cable 2, so as to apply the glue to the semi-finished cable 2. Along with the bunching of the three polymer hoses 6 by the bunching machine 7, the polymer hoses 6 are wound and tightly attached to the surface of the semi-finished cable 2 and adhered to the glue.

[0022] In a specific application scenario, the fire protection embedding module 8 is mainly applicable to the fire protection embedding link during the fire protection embedding process, that is, the fire protection embedding module 8 uses the scraper 815 and the glue storage box 818 to enable the equipment to realize embedding the polymer hose 6 in the cable in advance during the cable preparation process, so that when the cable encounters a fire and the outer sheath is damaged, the heat-damaged polymer hose 6 can quickly spray out the dry powder by using pressurized carbon dioxide, thereby extinguishing the ignition point and achieving the function of protecting the cable, greatly improving the safety of the cable and personnel and protecting the use function of the cable.

[0023] Referring to Figure 6 and Figure 7 In a preferred embodiment, a support frame 902 is bolted to the outside of the long sleeve 901. One side of the support frame 902 opposite to the wire bunching machine 7 is bolted. The long sleeve 901 is located outside the semi-finished cable 2. Three rectangular grooves 903 are circumferentially and equally spaced on the long sleeve 901. Air blowers 905 are arranged in the rectangular grooves 903. Three stabilizing seats 906 are circumferentially and equally spaced and bolted to the outside of the long sleeve 901. One end of a lever arm one 907 is rotatably connected to each stabilizing seat 906 through a bearing. One end of each lever arm one 907 is bolted to the outside of the air blower 905 on the same side, and the other end is rotatably connected to a lever arm two 908 through a bearing. One end of the three lever arms two 908 away from the lever arm one 907 is rotatably connected to the same integration ring 909 through a bearing. The inner wall of the integration ring 909 is slidably connected to the outside of the long sleeve 901. A thin opening is provided in the integration ring 909, and a fixing bolt 910 is arranged in the thin opening. A spiral guiding ring 904 is bolted to the inner wall of the long sleeve 901.

[0024] Specifically, after the polymer hose 6 is wound and adhered to the surface of the semi-finished cable 2 with glue, as the semi-finished cable 2 continues to move, the winding part of the semi-finished cable 2 and the polymer hose 6 moves into the long sleeve 901. The air blower 905 is started, and the air blower 905 blows on the semi-finished cable 2 and the polymer hose 6, thereby accelerating the drying of the glue. The fixing bolt 910 is loosened, and the fixing bolt 910 releases the locking of the integration ring 909. The integration ring 909 is pushed, so that the integration ring 909 moves on the surface of the long sleeve 901, and the lever arm two 908 drives the lever arm one 907 to rotate on the stabilizing seat 906, thereby changing the blowing angle of the air blower 905 on the semi-finished cable 2.

[0025] In a specific application scenario, the drying module 9 is mainly applicable to the drying link during the drying process. That is, the drying module 9 can greatly accelerate the drying speed of the glue on the semi-finished cable 2 by using the spiral guiding ring 904 and the air blower 905, improve the adhesion of the polymer hose 6 adhered to the semi-finished cable 2, thereby avoiding the situation of slippage of the polymer hose 6 wound on the semi-finished cable 2 caused by the un-dried glue, ensuring the stability of each structure in the cable, and improving the service performance of the cable.

[0026] Working principle: Start the motor 803. The motor 803 drives the toothed ring 805 meshed with the gear 804 to rotate, so that the twisting disc 5 gradually winds the three polymer hoses 6 around the outside of the semi-finished cable 2 during rotation. The polymer hoses 6 contain dry powder fire extinguishing agent and pressurized carbon dioxide. During the process of the semi-finished cable 2 being conveyed from the wire lead machine 3 to the bunching machine 7, start the pump 810. The pump 810 pumps the water in the infusion tube 808 into the storage bottle 807 into the nozzle 809 and sprays it out, making the surface of the semi-finished cable 2 wet. Under the elastic force of the spring 813, the movable rod 811 presses the arc-shaped plate 814 tightly against the surface of the semi-finished cable 2, so that the scraper 815 wipes off the dirt on the surface of the semi-finished cable 2. The glue storage box 822 conveys the stored glue to the glue storage box 818 through the conveying hose 823, so that the glue can flow into the space between the spacer bars 820 through the fine holes 819. Under the elastic force of the elastic reed 821, the spacer bars 820 are tightly attached to the surface of the semi-finished cable 2, so as to apply the glue on the semi-finished cable 2. Along with the bunching of the three polymer hoses 6 by the bunching machine 7, the polymer hoses 6 are wound and tightly attached to the surface of the semi-finished cable 2 and adhered to the glue. After the polymer hoses 6 are wound and adhered to the surface of the semi-finished cable 2 with glue, as the semi-finished cable 2 continues to move, the winding part of the semi-finished cable 2 and the polymer hoses 6 moves into the long sleeve 901. Start the fan 905. The fan 905 blows on the semi-finished cable 2 and the polymer hoses 6, so as to accelerate the drying of the glue. Loosen the fixing bolt 910. The fixing bolt 910 releases the locking of the integration ring 909. Push the integration ring 909, so that the integration ring 909 moves on the surface of the long sleeve 901, making the force arm two 908 drive the force arm one 907 to rotate on the stable seat 906, so as to change the blowing angle of the fan 905 on the semi-finished cable 2.
