[0052] Through the arrangement of the above-mentioned structure, the arrangement of the screw rod 22 and the hand-tightening nut 23, the scraping assembly can be quickly disassembled, and the arrangement of the elastic member 13 and the cleaning brush 2 enables the annular scraper 4 and the cleaning brush 2 to clean cables of different sizes, thereby expanding the scope of application of the device and making it more flexible to use.

[0053] Embodiment 4

[0054] In conjunction with Embodiments 1 to 3, please refer to Figure 3 , Figure 4 and Figure 6 As shown, the specific improvements are as follows: a sleeve 14 is fixedly connected to the outer surface of the cleaning brush 2, one end of the telescopic rod 133 extends to the interior of the sleeve 14, a through groove 15 is provided inside the telescopic rod 133, and baffles 16 are slidably provided on both sides of the inner wall of the through groove 15, a second spring 17 is fixedly connected between the two baffles 16, and a protrusion 18 is fixedly connected to the opposite sides of the two baffles 16, and a through hole 19 adapted to the protrusion 18 is provided on the surface of the sleeve 14.

[0055] By setting the above structure, after the protrusion 18 is pressed into the sleeve 14, the cleaning brush 2 and the elastic member 13 can be separated, and the cleaning brush 2 can be easily disassembled and replaced after aging, thereby extending its service life.

[0056] Embodiment 5

[0057] In conjunction with Embodiments 1 to 4, please refer to Figure 1 , Figure 7 and Figure 8 As shown, the specific improvements are as follows: a group of wiping components 28 includes two electric push rods 281 fixed on the surfaces of two vertical plates 27, the output ends of the two electric push rods 281 are provided with arc plates 282 through bolts, and the inner side of the arc plates 282 is provided with sponge pads 283 through a Velcro component, and the Velcro component includes a Velcro hook surface bonded to the inner side of the arc plates 282 and a Velcro velvet surface bonded to the sponge pad 283.

[0058] Through the arrangement of the above structure, the cleaned cable passes through the cleaning box 1, and is alternately dried by two groups of wiping components 28 to ensure the water absorption effect, which is beneficial to improving the subsequent drying efficiency, thereby improving the processing efficiency of the cable.

[0059] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0060] When in use, the cable is conveyed out of the cleaning box 1 through the first guide roller 24, the two conveying rollers 26 and the second guide roller 25, and passes through the hollow plate 3 and the two cleaning brushes 2 in sequence. The cable is immersed in the cleaning liquid in the cleaning box 1, and the setting of the annular scraper 4 is used to facilitate the removal of oil, dust and plastic residues on the surface of the cable. At the same time, by starting the motor 5, the transmission gear 7 is driven to rotate, and the transmission gear 7 drives the annular sleeve plate 9 to rotate through the hollow gear 8. The annular sleeve plate 9 drives the cleaning brush 2 to rotate through the elastic member 13, and the cable surface is further cleaned to improve the cleaning effect. Then, the cleaned cable passes between the wiping components 28, and the electric push rod 281 is started to drive the two sponge pads 283 to be combined, and the cable in the transmission process is contacted to absorb the moisture on its surface, so that when the cable is conveyed to the drying drum 35, the heating coil 36 dries the cable faster, and the cable with dried moisture enters the spray box 30, and the anti-corrosion material is evenly sprayed on the cable through multiple nozzles 33;

[0061] When the cable passes through the hollow plate 3 and the two cleaning brushes 2, the annular scraper 4 fits with the surface of the cable. By opening the box cover and screwing the hand nut 23 out of the screw rod 22, the hollow plate 3 can be disassembled from between the mounting plates 21, and then the scraping assembly of the corresponding size can be replaced according to the size of the cable. When the cable passes between the cleaning brushes 2, pressure is exerted on the cleaning brush 2, so that the telescopic rod 133 is squeezed, thereby squeezing the first spring 132 in the cylinder 131, and then under the elastic force of the first spring 132, the cleaning brush 2 can fit with cables of different sizes and brush them. After aging, the cleaning brush 2 presses the two protrusions 18 outside the sleeve 14, and the protrusions 18 squeeze the second spring 17, so that it can move into the sleeve 14, so that the cleaning brush 2 can be separated from the elastic member 13 and the cleaning brush 2 can be replaced;

[0062] After absorbing moisture, one set of wiping components 28 can be used alternately with the other set of wiping components 28. During the alternation, through the setting of the Velcro component, the staff can quickly tear off the sponge pad 283 that has absorbed moisture from the arc plate 282, and then paste a new sponge pad 283 for next use. The sponge pad 283 can be replaced without repeated shutdowns during the process.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
