[0027] In this embodiment, the roller 21 on the unloading mechanism 2 is driven by the first motor 22 to unroll the wallpaper body 23 on its surface, and the take-up mechanism 3 can take up the wallpaper body 23. Rollers 7 are installed inside the first mounting frame 4 and the second mounting frame 5. The second motor 51 is connected to the mounting shaft 71 to control the rotation of the rollers 7.

At the same time, the paint can be applied to both sides of the wallpaper body 23, improving the practicality of the device.

[0028] Example 2

[0029] like Figures 1-7As shown, a bidirectional lead screw 64 is rotatably installed inside the through hole 601. A second bevel gear 65 is fixedly installed at the bottom of the bidirectional lead screw 64. The side of the second bevel gear 65 meshes with the side of the first bevel gear 63. Threaded sleeve blocks 81 are fixedly installed at both the front and rear ends of the first sliding plate 8. The inside of the threaded sleeve blocks 81 is threadedly connected to the surface of the bidirectional lead screw 64. A scraper 82 and a scraper 83 are fixedly installed at the bottom of the first sliding plate 8. The scraper 82 and the scraper 83 are connected and combined in a V-shape. The first sliding plate 8 and the second sliding plate 9 have the same structure but opposite directions. The first sliding plate 8 and the second sliding plate 9 are respectively set at the upper and lower ends of the wallpaper body 23.

[0030] In this embodiment, bevel gear 63 meshes with bevel gear 65, and the third motor 61 is connected to the mounting rod 62, enabling it to drive the bidirectional lead screw 64 to rotate. A threaded sleeve 81 is threaded onto the surface of the bidirectional lead screw 64, allowing the rotation of the bidirectional lead screw 64 to move the threaded sleeve 81 and the first sliding plate 8 together. By setting the first sliding plate 8 and the second sliding plate 9 on the threads at both ends of the bidirectional lead screw 64, the first sliding plate 8 and the second sliding plate 9 can move relative to each other, allowing adjustment of the distance between them. The combined connection of scraper 1 82 and scraper 2 83 allows the wallpaper to be applied... Uneven paint on the main body 23 is smoothed out by scraping. The first scraper 82 and the second scraper 83 form a V-shape, allowing the paint scraped off by the first scraper 82 and the second scraper 83 to flow outward, preventing paint residue from accumulating on the surface of the first scraper 82 and the second scraper 83 and affecting the subsequent use effect. The first sliding plate 8 and the second sliding plate 9 can be set to smooth both sides of the wallpaper main body 23, and the distance between the first sliding plate 8 and the second sliding plate 9 can be adjusted, so as to facilitate the smoothing of the paint on the wallpaper main body 23 and ensure the coating quality of the wallpaper main body 23. The motors used in this application are all servo motors, which can control the forward and reverse rotation of their connecting parts.

[0031] Working principle: By coordinating the operation of the feeding mechanism 2 and the receiving mechanism 3, the wallpaper body 23 is unrolled and coated. One end of the wallpaper body 23 passes through the interior of the first mounting frame 4 and the second mounting frame 5. Two rollers 7 respectively abut against the two sides of the wallpaper body 23. Coating is added into the storage box 52. When coating is needed on the top of the wallpaper body 23, the solenoid valve 54 is opened to allow the coating to flow into the liquid guiding chamber 711 inside the mounting shaft 71. The diverter pipe 73 transports the coating to the surface of the coating cloth 72 to wet it. The second motor 51 drives the mounting shaft 71 and the rollers 7 to rotate, causing the coating on the coating cloth 72 to adhere to the surface of the wallpaper body 23, thus completing the coating operation of the wallpaper body 23. When coating is needed on both sides of the wallpaper body 23... During coating, simply activate the solenoid valve 54 inside the first mounting bracket 4 to wet the coating cloth 72 on the bottom roller 7, facilitating simultaneous coating of both sides of the wallpaper body 23. After coating, the wallpaper body 23 passes through the through hole 601, and the scrapers 82 and 83 at the top and bottom ends respectively smooth out the uneven coating on both sides of the wallpaper body 23. When it is necessary to adjust the coating thickness on the wallpaper body 23, the third motor 61 is activated to drive the bidirectional lead screw 64 to rotate, causing the first sliding plate 8 and the second sliding plate 9 to move closer together. Conversely, the third motor 61 drives the bidirectional lead screw 64 to reverse, causing the first sliding plate 8 and the second sliding plate 9 to move away from each other, facilitating the adjustment of the height of the scrapers 82 and 83.
