[0024] The prior art eliminates the water vapor on the machine rollers by installing a heating and drying device on the surface of the machine roller group. However, when the moisture content in the air is high, the machine rollers rotate quickly and the heating and drying device cannot eliminate the water vapor attached to the machine rollers in time. Therefore, a water vapor elimination device between paper machine roller groups is needed, which can quickly remove the water vapor on the surface of the machine rollers.

[0025] like Figure 1-2 As shown, the device comprises a machine roller body 1, support frames 2 for fixed installation are installed on both sides of the machine roller body 1, a scraping component 3 for scraping and wiping water vapor is arranged outside the machine roller body 1, and an adjusting component 4 for adjusting the height is arranged outside the scraping component 3. The scraping component 3 can be installed on the outer surface of the machine roller body 1 to scrape the adsorbed water vapor on the outer surface of the machine roller body 1, and the scraping component 3 can be adjusted up and down by the adjusting component 4, so that the scraping component 3 can be disassembled and replaced conveniently;

[0026] First, the specific structure of the scraping assembly 3 is disclosed. The scraping assembly 3 includes two connecting blocks 301. A scraping plate 302 for scraping the air on the surface of the machine roller body 1 is installed in the middle of the two connecting blocks 301. An wiping plate 303 for wiping water vapor is installed in the middle of the two connecting blocks 301. Two wiping plates 303 are provided. A connecting plate 6 for connecting and fixing is installed in the middle of the two wiping plates 303. The two wiping plates 303 are installed on the back of the scraping plate 302.

[0027] When removing the water vapor on the outer surface of the roller body 1, the roller body 1 rotates, and the rubber scraper head at the bottom of the scraper plate 302 can preliminarily remove the water vapor on the outer surface of the rotating roller body 1. The scraped water will slide down along the two ends of the scraper plate 302, and two erasing plates 303 are installed between the two connecting blocks 301 on the back of the scraper plate 302. The bottoms of the two erasing plates 303 are provided with water-absorbing materials, which can wipe the residual water vapor on the roller body 1. The two erasing plates 303 wipe the outer surface of the roller body 1 twice to completely remove the water vapor, thereby achieving the effect of quickly removing the water vapor on the outer surface of the roller body 1. The water vapor can be removed from the rapidly rotating roller body 1.

[0028] The improvement of this embodiment is that the scraping plate 302 and the wiping plate 303 structure can achieve the effect of eliminating water vapor from the rapidly rotating machine roller body 1, thereby solving the problem in the prior art that the machine roller body 1 cannot eliminate water vapor in time when it rotates rapidly.

[0029] Since the erasing plate 303 in the prior art needs to be replaced and disassembled after work, it is inconvenient to adjust and disassemble. Figure 3 A second embodiment of the present utility model is shown.

[0030] The specific structure of the adjustment component 4 is disclosed again. The adjustment component 4 includes a movable plate 401 that can move up and down. The internal thread of the movable plate 401 is connected to a screw rod 402. The top of the screw rod 402 is fixedly installed with a rotating plate 403. The movable plate 401 is fixedly installed on the outside of the connecting block 301. The movable plate 401 is installed in a slide groove opened on the outer surface of the mounting seat 5. The top of the screw rod 402 passes through the slide groove and extends to the outside of the mounting seat 5. The top of the support frame 2 is installed with a mounting seat 5 for installing the rotating shafts at both ends of the machine roller body 1.

[0031] After the work of the erasing plate 303 is completed, it needs to be disassembled and maintained. The two movable plates 401 are installed at both ends of the two connecting blocks 301. The movable plates 401 are installed in the slide grooves opened on the outer surfaces of the two mounting seats 5. By rotating the rotating plates 403 outside the mounting seats 5, the movable plates 401 can be moved up and down on the outer surface of the screw rod 402. The movable plates 401 move upward, driving the scraping plates 302 and the erasing plates 303 to move upward together, so that the erasing plates 303 can be replaced and disassembled conveniently, thereby achieving the effect of disassembling and replacing the scraping assembly 3.

[0032] The improvement of this embodiment is that the structure of the screw rod 402 and the movable plate 401 can realize the effect of lifting and lowering the scraping assembly 3 for easy replacement and disassembly.

[0033] In summary, the working principle of this solution is as follows:

[0034] When removing the water vapor from the outer surface of the roller body 1, the roller body 1 rotates, and the rubber scraper head at the bottom of the scraper plate 302 can preliminarily remove the water vapor from the outer surface of the rotating roller body 1. The scraped water will slide down along the two ends of the scraper plate 302, and two erasing plates 303 are installed between the two connecting blocks 301 on the back of the scraper plate 302. The bottom of the two erasing plates 303 are provided with water-absorbing materials, which can wipe the residual water vapor on the roller body 1. The two erasing plates 303 wipe the outer surface of the roller body 1 twice to completely remove the water vapor, so as to achieve the effect of quickly removing the water vapor from the outer surface of the roller body 1. The water vapor can be removed from the rapidly rotating roller body 1;

[0035] After the work of the erasing plate 303 is completed, it needs to be disassembled and maintained. The two movable plates 401 are installed at both ends of the two connecting blocks 301. The movable plates 401 are installed in the slide grooves opened on the outer surfaces of the two mounting seats 5. By rotating the rotating plates 403 outside the mounting seats 5, the movable plates 401 can be moved up and down on the outer surface of the screw rod 402. The movable plates 401 move upward, driving the scraping plates 302 and the erasing plates 303 to move upward together, so that the erasing plates 303 can be replaced and disassembled conveniently, thereby achieving the effect of disassembling and replacing the scraping assembly 3.
