[0029] Cleaning unit includes shaft 305 and cleaning brush 306, and the middle part of the side close to each other of gear 304 is fixedly connected to the two ends of cleaning brush 306 respectively, and cleaning brush 306 is fixedly connected to the middle part of shaft 305, so as to provide the rotation axis of cleaning brush 306 and enable it to rotate automatically with the rotation of gear 304.The bristles of cleaning brush 306 are attached to carrier roller 2.The bristles of cleaning brush 306 are made of nylon material, and the bristles are closely attached to the surface of carrier roller, which can effectively remove dirt and residues on carrier roller 2 by rotating.The bristles made of nylon material have excellent properties such as high temperature resistance, wear resistance and corrosion resistance, and are suitable for long-term work in high-temperature drying box.

[0030] Example two:

[0031] On the basis of implementation one, the right side of the box 1 is provided with a dust collection structure, which includes a motor 401, a suction pump 402, a collection box 501, a filter screen plate 502, a handle 503, a collection pipe 504 and a connecting seat 505. One end of the collection pipe 504 penetrates through the right side of the box 1, and the other end of the collection pipe 504 is arranged in the collection box 501 as a storage container for dust. The collection box 501 can accommodate a large amount of dust and impurities, facilitating subsequent cleaning and processing. A through hole is formed in the upper part of the collection box 501, and a filter screen plate 502 is arranged in the through hole. The connecting seat 505 is arranged at the front and rear ends of the filter screen plate 502, and the filter screen plate 502 is slidingly connected to the connecting seat 505. The handle 503 is fixedly connected to the upper surface of the filter screen plate 502. The suction pump 402 is arranged on the right side of the collection box 501, and the dust and impurities in the box 1 are sucked into the collection pipe 504 through the negative pressure generated by the suction pump 402, realizing the collection of dust. The motor 401 is connected to the suction pump 402 to provide power for the suction pump 402. The filter screen plate 502 is composed of a frame and a filter screen. The filter screen is a HEPA filter screen. The HEPA filter screen has a very high filtering efficiency and can capture and filter out harmful substances such as small particles and bacteria in the air, ensuring the cleanliness of the discharged air.

[0032] Working principle: the wire to be dried is put into the feeding port 102, conveyed by the supporting roller 2 into the drying box for drying, and the dried wire is discharged from the discharging port 101. The supporting roller 2 is a key component for conveying the wire, and rotates to move the wire uniformly and stably in the drying box, thereby ensuring the consistency of the drying effect. When the supporting roller 2 needs to be cleaned, the electric push rod 302 is started to drive the sliding block 307 to slide in the sliding groove of the sliding seat 301. The sliding of the sliding block 307 drives the gear 304 to move along the rack 303. Since the gear 304 is connected to the cleaning brush 306 through the shaft 305, the rotation of the gear 304 will drive the cleaning brush 306 to rotate. The bristles of the cleaning brush 306 closely fit the surface of the supporting roller 2, and effectively remove the dirt and residues on the supporting roller through rotation.

[0033] At the same time, the motor 401 is started to provide power for the suction pump 402. The suction pump 402 generates negative pressure, and the dust and impurities in the box 1 are sucked into the collection box 501 through the collection pipe 504. The sucked dust and impurities first pass through the filter screen plate 502, and the HEPA filter screen can capture and filter out harmful substances such as small particles and bacteria in the air.

[0034] It is to be noted that, as used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component" can include a combination of two or more components. Similarly, the terms "one" and "the" do not exclude the presence of more than one item, unless the context clearly indicates otherwise. Further, the terminology "an" and "one" are used in the detailed description and claims only to mean one or more, at least one, or "at least one." Finally, the words "comprise," "comprises," and "comprising" and the like, are to be construed in their broadest, intended, and open ended form to encompass events that would otherwise prevent a process, method, article, or apparatus from being encompassed by the claim.
