[0037] The working principle of the cable outer conductor copper strip winding pressure wheel device provided by the present utility model is as follows:

[0038] The first step: The device main body 1 is a copper strip winding and pressing wheel device for the outer conductor of the cable. During use, the copper strip winding and pressing wheel for the outer conductor of the cable will generate a certain amount of heat during high-speed operation. Therefore, heat dissipation is very important. By dissipating heat, overheating of the pressing wheel can be prevented, its service life can be extended, and at the same time, the production quality of the cable can be ensured.

[0039] The second step: When heat dissipation is required, the rear space is pre-cooled by the Peltier cooler 19. Since the materials of the two metal plates 11, the second metal plate 12 and the two metal filter plates 13 are all metals, the temperature can be transferred. Therefore, when air comes into contact with them, the air can be cooled.

[0040] The third step: Start the fan 6. The fan 6 discharges air into the left space. Then the air passes through the first filter plate 7 and enters the first middle space. The first filter plate 7 can preliminarily filter the passing air. After that, the air sequentially passes through the electrostatic precipitation filter net, the HEPA filter net, the activated carbon filter plate and the second filter plate 8 and enters the lower space. When the air passes through the electrostatic precipitation filter net, the principle of electrostatic adsorption can be used to capture the particles in the air. The HEPA filter net can filter dust, bacteria, viruses and smoke. The activated carbon filter plate can adsorb the odor, harmful gases and some particles in the air. Therefore, the air can be filtered by the electrostatic precipitation filter net, the HEPA filter net and the activated carbon filter plate, so as to improve air purification.

[0041] The fourth step: The purified air enters the lower space and will contact the two metal plates 11, the second metal plate 12 and the two metal filter plates 13, so that the temperature of the purified air can be reduced. After that, the air passes through the third filter plate 9 and enters the right space, and then is discharged into the device main body 1 through the first drying plate 14, the second drying plate 15, the third drying plate 16 and the connecting pipe 17. The end of the connecting pipe 17 extending into the device main body 1 needs to be aligned with the pressing wheel and does not interfere with the operation of the pressing wheel. Therefore, the air after purification and cooling can be used to dissipate heat and cool the pressing wheel, preventing the pressing wheel from overheating, so its service life can be extended.
