An adjusting roller is movably connected to the top cover, and a stroke groove is opened through the top of the top cover. The second rotating shaft is slidably connected to the stroke groove. A rubber inner sleeve is sleeved on the roller wall of the adjusting roller and the two transmission rollers. The sandpaper outer sleeve is sleeved on the outer wall of the rubber inner sleeve, and the height of the sandpaper outer sleeve is less than the height of the rubber inner sleeve. Cleaning rollers are symmetrically arranged on both sides of the adjusting roller and are fixedly inserted into the bottom of the top cover by a fixed shaft. Rotating collars are rotatably sleeved on the top and bottom of the cleaning rollers. The rotating collars and the cleaning rollers abut against the outer walls of the rubber inner sleeve and the sandpaper outer sleeve, respectively.

[0006] Preferably, a groove is provided at the connection between the top cover and the outer shell, and a handle is provided inside the groove. The handle inside the groove allows the user to easily hold and smooth the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The present invention provides the following technical solution:

[0021] Example 1: A wall paint smoothing device for building construction includes an outer shell 2 with an opening on one side, a top cover 1 fixedly installed on the top of the outer shell 2, and a bottom cover 3 snapped into the bottom of the inner shell 2. A first rotating shaft 6 is rotatably inserted into the bottom of the top cover 1, and a motor 8 for driving the first rotating shaft 6 is fixedly installed thereon. Two first rotating shafts 6 are symmetrically arranged, and transmission rollers 7 are fixedly sleeved on the shaft walls of both first rotating shafts 6. Sandpaper bushings 14 are commonly sleeved on the roller walls of both transmission rollers 7. The connection between the top cover 1 and the outer shell 2... A groove 4 is provided at the joint, and a handle 5 is provided inside the groove 4. The output end of the motor 8 moves through the top cover 1 and is fixedly sleeved with the first transmission wheel 9. The first rotating shaft 6 passes through one end of the top cover 1 and is fixedly sleeved with the second transmission wheel 10. The first transmission wheel 9 and the second transmission wheel 10 are connected by a transmission belt 11. A dust cover 12 is installed on the top of the top cover 1 at the positions of the first transmission wheel 9, the second transmission wheel 10 and the transmission belt 11. The first transmission wheel 9, the second transmission wheel 10 and the transmission belt 11 are all located inside the dust cover 12.

[0022] In use, the motor 8 is started by the controller. When the motor 8 starts under the control of the controller, it can drive the first transmission wheel 9 to rotate. The first transmission wheel 9 then drives the second transmission wheel 10 to rotate synchronously through the transmission belt 11. The second transmission wheel 10 drives the coaxial transmission roller 7 to rotate. When the two transmission rollers 7 rotate, they can drive the sandpaper outer sleeve 14 that is sleeved on the roller wall to rotate. The device can be held and smoothed by holding the handle 5. The side of the outer shell 2 with the opening is placed against the wall. When the sandpaper outer sleeve 14 with the opening is rotated, it can sand the wall surface, thereby achieving the smoothing of the wall surface.

[0023] Example 2: Based on Example 1, this example also includes an adjusting roller 16 rotatably connected to the bottom of the top cover 1 via a second rotating shaft 15. A stroke groove 17 is provided through the top of the top cover 1. The second rotating shaft 15 is slidably connected to the stroke groove 17. A toggle block 18 is rotatably connected to one end of the second rotating shaft 15 that passes through the stroke groove 17. A spring 19 is connected to the other end of the toggle block 18. A fixing block 20 is connected to the other end of the spring 19. The fixing block 20 is fixedly installed on the top of the top cover 1. A telescopic rod 21 is provided between the fixing block 20 and the toggle block 18. The bottom of the second rotating shaft 15 and the bottom of the first rotating shaft 6 are rotatably connected to the bottom cover 3.

[0024] Similarly, the motor 8 can be used to drive the sandpaper outer sleeve 14 to rotate and sand the wall surface. When the sandpaper outer sleeve 14 wears out after long-term use, it needs to be replaced. At this time, the bottom cover 3 is opened, and the second rotating shaft 15 loses the limit of the bottom cover 3, so the actuating block 18 can be pushed. In the process of pushing against the elastic force of the spring 19, the actuating block 18 can drive the adjusting roller 16 on the shaft wall of the second rotating shaft 15 to move, so that the height of the equilateral triangle formed by the adjusting roller 16 and the two transmission rollers 7 is shortened, thereby shortening its side length, making it easier to remove the sandpaper outer sleeve 14. After removing it, a new sandpaper outer sleeve 14 is replaced and the bottom cover 3 is closed, so that the disassembly and assembly of the sandpaper outer sleeve 14 can be completed conveniently.

[0025] Example 3: Based on Example 2, this example also includes a rubber inner sleeve 13 sleeved on the roller walls of the adjusting roller 16 and the two transmission rollers 7. The sandpaper outer sleeve 14 is sleeved on the outer wall of the rubber inner sleeve 13, and the height of the sandpaper outer sleeve 14 is less than the height of the rubber inner sleeve 13. Cleaning rollers 23 are symmetrically arranged on both sides of the adjusting roller 16 and are fixedly inserted into the bottom of the top cover 1 by a fixed shaft 22. Rotating collars 24 are rotatably sleeved on the top and bottom of the cleaning rollers 23. The rotating collars 24 and the cleaning rollers 23 respectively abut against the outer walls of the rubber inner sleeve 13 and the sandpaper outer sleeve 14.

[0026] In use, the rubber inner sleeve 13 is fitted onto the roller walls of the adjusting roller 16 and the two drive rollers 7, and then the sandpaper outer sleeve 14 is fitted onto the outer wall of the rubber inner sleeve 13. The rubber inner sleeve 13 can increase the friction between the sandpaper outer sleeve 14 and the roller walls of the adjusting roller 16 and the two drive rollers 7, thereby improving its transmission effect and preventing the sandpaper outer sleeve 14 from slipping. Furthermore, the cleaning roller 23, which is in contact with the outer wall of the sandpaper outer sleeve 14 but does not rotate, can clean the outer surface of the sandpaper outer sleeve 14 when it rotates, preventing excessive material from adhering to the outer surface of the sandpaper outer sleeve 14 and reducing the sanding effect. In addition, the rotating collar 24 can limit and support the rubber inner sleeve 13, increasing the wrap angle between the rubber inner sleeve 13 and the adjusting roller 16 and the two drive rollers 7, which can further improve the transmission effect between the adjusting roller 16, the drive rollers 7 and the rubber inner sleeve 13.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
