[0040] Example 4

[0041] Based on Example 3, the structure is as follows: Figure 5 As shown, the wiping unit 3 includes a U-shaped connecting plate 33. Each outer wall of the U-shaped connecting plate 33 is provided with a slider 38, and each slider 38 is mounted on a slide rail 37. The two slide rails 37 are respectively mounted on two parallel inner walls of the movable frame 35, and are arranged along the axial direction of the movable frame 35. A wiping head 36 is hinged to the end of the movable frame 35. A sliding nut 31 and several transverse sliders 32 are provided on the closed end face of the U-shaped connecting plate 33. The closed end face of the U-shaped connecting plate 33 is located close to the lead screw 48, and the open end of the U-shaped connecting plate 33 is away from the lead screw 48. Each horizontal sliding slider 32 is slidably connected to the support frame 1. Specifically, each horizontal sliding slider 32 is slidably connected to the horizontal guide rail 18. The sliding nut 31 is connected to the transmission unit 2. Specifically, the sliding nut 31 is threadedly connected to the lead screw 48. The two side walls of the U-shaped connecting plate 33 are connected by the support plate 39. The support plate 39 is perpendicular to the closed end face of the U-shaped connecting plate 33. The support plate 39 is inserted into the cylinder of the hydraulic cylinder 34. That is, the support plate 39 is used to support and connect the hydraulic cylinder 34. The piston end of the hydraulic cylinder 34 is connected to the end of the wiping head 36 connected to the moving frame 35.

[0042] By activating the hydraulic motor 45, the second driving pulley 494 rotates. The second driving pulley 494 drives the second driven pulley 46 to rotate via the second toothed transmission belt 47. The second driven pulley 46 drives the lead screw 48 to rotate. The lead screw 48 drives the sliding nut 31 to move along the lead screw 48, thereby driving the U-shaped connecting plate 33, the moving frame 35, and the wiping head 36 to move synchronously along the axial direction (X-axis direction) of the roll. At this time, the transverse slider 32 slides along the transverse guide rail 18 to improve the stability of the movement. By activating the hydraulic cylinder 34, the moving frame 35 is pushed to move closer to the roll (along the radial direction or Y-axis direction of the roll), thereby driving the wiping head 36 to move so that the wiping head 36 is in contact with the roll surface. During the movement of the moving frame 35, it slides along the slider 38 via the slide rail 37, thereby ensuring that the moving frame 35 moves in the horizontal direction and improving stability.

[0043] Example 5

[0044] Based on Example 4, the structure is as follows: Figure 6 As shown, the wiping head 36 includes a hollow head shell 361. The two ends of the head shell 361 are hinged to the movable frame 35. Two parallel first scrapers 362 are provided on the surface of the head shell 361 on the same side as the sliding nut 31. Two parallel second scrapers 363 are provided on the surface of the head shell 361 away from the hydraulic cylinder 34. Several elongated holes 364 are provided on the head shell 361 and between the two first scrapers 362. Several elongated holes 364 are provided on the head shell 361 and between the two second scrapers 363.

[0045] The end of the head housing 361 away from the second scraper 363 is connected to a suction pipe 2. The suction pipe 2 communicates with the interior of the head housing 361 and passes through the movable frame 35. The end of the suction pipe 2 away from the head housing 361 is connected to a vacuum suction device.

[0046] The pollutants scraped off by the first scraper 362 and the second scraper 363 fall into the head housing 361 through the elongated hole 364. The pollutants are then sucked out and cleaned by activating the vacuum suction device through the suction pipe 2.

[0047] Example 6

[0048] Based on Example 5, the structure is as follows Figure 7As shown, the suction pipe 2 includes two parallel inner moving pipes 26. One end of each inner moving pipe 26 is connected to the head housing 361, and the other end of each inner moving pipe 26 passes through the end of the moving frame 35 and is inserted into the guide pipe 24. The inner moving pipe 26 can move along the inside of the guide pipe 24. The ends of the two guide pipes 24 away from the inner moving pipes 26 pass through the support plate 39 and are respectively connected to the two horizontal ports of the transition pipe 23. The vertical port of the transition pipe 23 is connected to the external moving pipe 21. The external moving pipe 21 is connected to the external fixed pipe 27 through a hose 28. The external fixed pipe 27 is connected to the archway 5. The end of the external fixed pipe 27 away from the external moving pipe 21 is connected to the vacuum suction device. The hose 28 is laid in the hose guide groove 19. The hose guide groove 19 is used to guide the hose 28 to avoid entanglement or kinking when the wiping head 36 moves along the roller axis, which would affect the suction effect.

[0049] A filter screen 22 is installed inside the connection between the external moving pipe 21 and the transition pipe 23, and a dustproof ring 25 is installed at the connection between the guide pipe 24 and the internal moving pipe 26. The dustproof ring 25 is installed to improve the sealing and ensure the suction effect.

[0050] Example 7

[0051] Based on embodiment 6, each slider 38 is provided with a support beam 391 on the side wall away from the slide rail 37. The support beam 391 is located at the bottom of the guide tube 24 and is used to support the guide tube 24.

[0052] Example 8

[0053] Based on embodiment 7, the movable frame 35 includes two parallel movable beams 351. One set of the movable beams 351 is connected to the closed end of the U-shaped fixing plate 352 at the same side. The open end of the U-shaped fixing plate 352 is hinged to both ends of the head shell 361. An inner movable tube 26 is inserted into the closed end of the U-shaped fixing plate 352. The U-shaped fixing plate 352 can support the inner movable tube 26. The two movable beams 351 are symmetrically arranged with slide rails 37. The side of the two movable beams 351 away from the closed end of the U-shaped connecting plate 33 is connected by several crossbeams 353. Several crossbeams 353 are arranged sequentially at the bottom of the guide tube 24 and the inner movable tube 26. By setting several crossbeams 353, the stability of the movable frame 35 is improved, and the guide tube 24 and the inner movable tube 26 are supported.

[0054] The specific working process of the roll wiping device in this embodiment is as follows: By starting the motor 42, the motor 42 drives the first driving pulley 492 to rotate. The first driving pulley 492 drives the first driven pulley 493 to rotate via the first toothed transmission belt 43. The first driven pulley 493 drives the synchronous shaft 41 to rotate. The synchronous shaft 41 drives two worm gears to rotate. The worm gears drive the worm to move up and down, and through the lifting connector 44, drive the lifting plate 14 to move up and down along the lifting guide rail 15, thereby adjusting the roll gap between the wiping head 36 and the rotating rolls in the vertical direction (Z-axis direction). By starting the hydraulic cylinder 34, the moving frame 35 is pushed towards the rolls (along the radial or Y-axis direction of the rolls), thereby driving the wiping head 36 to move so that the wiping head 36 fits against the roll surface. During this process, the moving tube 26 continuously extends out of the guide tube 24. When the leveling machine is working... The support roller and work roller surfaces (roll surface) can be wiped and cleaned. The first scraper 362 and the second scraper 363 clean the surfaces of the support roller and the work roller simultaneously. As the roll rotates, the roll surface is continuously wiped, thus cleaning the roll surface. After the current roll surface is cleaned, the hydraulic motor 45 is started. The hydraulic motor 45 drives the second drive pulley 494 to rotate. The second drive pulley 494 drives the second driven pulley 46 to rotate through the second toothed transmission belt 47. The second driven pulley 46 drives the lead screw 48 to rotate. The lead screw 48 drives the sliding nut 31 to move along the lead screw 48, thereby driving the U-shaped connecting plate 33, the moving frame 35, and the wiping head 36 to move synchronously along the axial direction (X-axis direction) of the roll to wipe and clean other parts of the roll surface, so that the wiping head 36 can wipe and clean the entire roll surface. During the wiping process, the pollutants removed fall into the head shell 361 through the elongated hole 364. The pollutants are then sucked away by the vacuum suction device, intercepted by the filter screen 22, and stored in the transition tube 30 and guide tube 31 for environmental protection treatment before being recycled.

[0055] This utility model of a roll wiping device has a compact structure, requires little installation space, and has high roll surface cleaning efficiency. It not only reduces the incidence of surface defects and effectively improves product quality, but also extends roll life and reduces production costs. It can be widely used in various dry leveling equipment.
