[0002] During the manufacturing process of metal plates, metal is continuously formed into coils through processes such as rolling or extrusion, which is convenient for long-distance transportation and warehouse storage. When used later, a cross-cutting shear is needed to cut the metal coils into flat sheets of the required length and stack them.

[0003] It is inevitable that metal coils will deform and bend during transportation. If they are not leveled before cutting, the cuts will be skewed, affecting the subsequent positioning of the plates. When leveling the metal plates before cutting, fine dust particles and other debris will inevitably adhere to the surface of the metal coils during long-distance transportation. When there are dust particles and other debris on the surface of the metal plate, the leveling equipment will press shallow grooves on the surface of the metal plate or scratch the surface of the metal plate, thus affecting the quality of the subsequent products.

The track groove 416 is a circular groove, and the bottom of the track groove 416 is a wavy line structure.

[0059] When the contact shaft 419 slides along the track groove 416, the spring 421 and the contact shaft 419 cooperate to make the cleaning frame 401 reciprocate along the axial direction of the second rotating shaft 417, thereby increasing the coverage area and cleaning effect of the brush roller 403 and the wiping roller 402, and further improving the cleaning effect of the metal plate. At the same time, the reciprocating motion facilitates the shaking off of dust in the self-cleaning mechanism 5, and improves the dust cleaning effect in the self-cleaning mechanism 5.

The cleaning box 503 is sleeved on the reciprocating screw 502 through the reciprocating screw 502 and is threadedly connected thereto.

[0061] The second motor 422 drives the first rotating shaft 501 to move, thereby driving the reciprocating screw 502 to rotate, so that the cleaning box 503 slides back and forth along the reciprocating screw 502 to clean the brush roller 403 and the wiping roller 402, and discharges the cleaned garbage to keep the brush roller 403 and the wiping roller 402 clean, thereby improving the cleaning effect of the equipment and reducing the maintenance cost of the equipment.

[0062] Furthermore, the wiping roller 402 is made of sponge, the surface of the brush roller 403 is provided with bristles, the side of the cleaning box 503 is provided with a scraper 506 that is in contact with the wiping roller 402, and a cleaning tooth 507 that is in contact with the brush roller 403, the angle between the scraper 506 and the cleaning tooth 507 and the horizontal plane is 15-30°, and the cleaning tooth 507 is a spiral structure.

[0063] The scraper 506 is used to scrape off the stains wiped by the wiping roller 402, so that the stains slide along the upper end surface of the scraper 506 into the cleaning box 503, and the cleaning teeth 507 scrape off the mixed fibers and debris on the brush roller 403, so that they slide into the cleaning box 503. The spiral scraping tooth structure enables it to have a better combing effect when it moves axially along the reciprocating screw rod 502.

[0065] When the cleaning box 503 moves to the upper end of the discharge hopper 420, the discharge cover 508 is opened to discharge the materials. When the cleaning box 503 leaves the discharge hopper 420, the discharge cover 508 is fixed to the bottom of the cleaning box 503 under the adsorption action of the first magnet 510 and the second magnet 511 to hold the materials.

[0067] When the cleaning box 503 is close to the discharge hopper 420, the top of the discharge hopper 420 squeezes the stop block 509, causing the discharge cover 508 to flip downward along the hinge, thereby opening the discharge cover 508 for discharge. When the cleaning box 503 is away from the discharge hopper 420, the edge of the upper end surface of the discharge hopper 420 squeezes the lower end surface of the discharge cover 508, causing it to flip upward. When it is close to the cleaning box 503, it is adsorbed on the lower end of the cleaning box 503 under the suction force of the first magnet 510 and the second magnet 511 to maintain a seal. The discharge hopper 420 passes through the cleaning frame 401, and a garbage bag can be fixed at the end of the discharge hopper 420 to collect garbage in a centralized manner.

During the cleaning process, the second motor 422 drives the reciprocating screw rod 502 to rotate The reciprocating screw rod 502 drives the cleaning box 503 to move along the brush roller 403 and the wiping roller 402, and the scraper 506 and the cleaning teeth 507 collect the attached stains and debris into the cleaning box 503. When the cleaning box 503 moves above the discharge hopper 420, the discharge hopper 420 hits the block 509, and the discharge cover 508 is automatically opened under the action of the lever, and the collected garbage is poured into the discharge hopper 420.
