[0043] Working principle: The cable is moved along the frame 1 by a traction mechanism, and passes through the coating solution container 4. A pump delivers flame-retardant coating through the first pipe 5 into the coating solution container 4. The first drive motor 6 is started, driving the stirring shaft 7 to rotate, which in turn drives the stirring blades 8 to rotate, stirring the flame-retardant coating in the coating solution container 4 to ensure uniformity of composition and prevent sedimentation or stratification, thus avoiding performance defects caused by compositional differences. The flame-retardant coating is then delivered to the annular pipe 9 by a micro-pump and coated on the outside of the cable using a nozzle 10. After the coating is applied, the excess coating is scraped off by the scraper ring 17 to make the coating thickness uniform. Then, the electric dryer 141 heats and dries the flame-retardant coating on the cable. After being heated and dried, the cable passes through the guide tube 15 and the wiping cotton tube 16 to the middle of the second pressure roller 392 and the first pressure roller 37. By controlling the extension and retraction of the electric push rod 393 and manually rotating the adjusting wheel 391, the second threaded rod 39 is rotated, which drives the lifting block 38 to move up and down, thereby adjusting the second pressure roller 392 and the first pressure roller 37 to correct the position of the cable.

[0044] The second drive motor drives the first threaded rod 31 to rotate, which in turn moves the moving block 33, thereby adjusting the position of the correction auxiliary mechanism. Afterwards, the fan 147 is started to generate circulating airflow. The cable is heated and dried, generating heat. The cable, after exiting the wiping cotton tube 16, comes into contact with the air in the frame 1 for cooling, causing a relative increase in temperature inside the frame 1. Odors from this contact are released into the air inside the frame 1. The fan 147 is then started again, generating airflow. The gas inside the frame 1 travels along the first exhaust pipe 143 to the filter box 148. The hot airflow passes through the first exhaust pipe... The cold water in the air pipe 143 and water tank 142 exchanges heat with the hot air in the first exhaust pipe 143, thereby cooling the gas in the first exhaust pipe 143. The gas passes through the activated carbon adsorption layer 145 and the zeolite adsorption layer 146 for filtration, filtering impurities in the air onto the activated carbon adsorption layer 145 and the zeolite adsorption layer 146, thereby reducing odor in the frame 1. After circulating through the filter box 148, the airflow, after filtration and cooling, reaches the frame 1 through the second exhaust pipe 144, and cools the flame-retardant coating on the cables in the frame 1 again.

[0045] The water in the activated carbon adsorption layer 145, the zeolite adsorption layer 146, and the water tank 142 is replaced regularly.
