[0002] Architectural decoration refers to the various treatments applied to the interior and exterior surfaces and spaces of a building using decorative materials or ornaments to protect its main structure, improve its physical performance, functionality, and aesthetics. When decorating a building, painting is generally required on its walls. However, unevenness can easily occur during the painting process. To ensure the final finish, appropriate wall sanding equipment is typically needed to sand the walls.

A first sealing rotating member 381 is fixedly fastened at one end of the L-shaped tube 38 near the first suction tube 34. The first suction tube 34 is fixedly installed in the middle of the first sealing rotating member 381. By setting the first sealing rotating member 381, the high-speed rotation of the first suction tube 34 is not affected when the L-shaped tube 38 is fixed.

[0040] The L-shaped tube 38 is fixedly fitted with a second sealing rotating member 382 at one end away from the first suction tube 34. The second suction tube 383 is fixedly installed in the middle of the second sealing rotating member 382.

[0042] The top end of the first tube 321 is fixedly fitted with a third sealing rotating member 392. A fourth suction tube 393 is fixedly installed in the middle of the third sealing rotating member 392. A second fixing bracket 394 is fixedly installed on the outside of the fourth suction tube 393. The second fixing bracket 394 is fixedly installed on the top end of the first bracket 313. By setting the third sealing rotating member 392, the rotation of the first tube 321 is not affected when the fourth suction tube 393 is fixed.

[0043] The recycling mechanism 4 includes a recycling bin 41, which is fixedly installed at the top of the device base 1. A water inlet pipe 411 is fixedly installed on one side of the top of the recycling bin 41, through which powder mixing water is injected into the recycling bin 41.

[0044] An observation window 415 is fixedly installed on the recycling bin 41, through which the collection and mixing of floating powder and water in the recycling bin 41 can be observed.

[0045] A discharge pipe 413 is fixedly installed at the bottom of the recycling bin 41, and a discharge valve 414 is fixedly installed on the discharge pipe 413. By controlling the opening of the discharge valve 414, the collected and mixed floating powder is discharged, thereby recycling the floating powder. A feed cylinder 42 is fixedly clamped in the middle of the feed pipe 412. The bottom of the feed cylinder 42 has a plurality of evenly distributed discharge ports 421 integrally formed. A one-way component 43 is provided in the feed pipe 412.

[0046] The one-way component 43 includes an inner slide 431 and a sealing ring 432. The inner slide 431 is fixedly engaged in the middle of the discharge port 421, and the sealing ring 432 is fixedly engaged in the end of the discharge port 421 away from the feed cylinder 42. A telescopic shaft 433 is slidably inserted in the middle of the inner slide 431. A sealing disc 434 is fixedly installed at one end of the telescopic shaft 433. The sealing disc 434 is movably engaged in the sealing ring 432. A limit ring 435 is fixedly installed at the end of the telescopic shaft 433 away from the sealing disc 434. A spring 436 is movably sleeved on the outside of the telescopic shaft 433 between the inner slide 431 and the limit ring 435. The floating powder in the feed pipe 412 is introduced into the feed cylinder 42 and into multiple discharge ports 421. At the same time, the sealing disc 434 is automatically pushed to move and disengage from the sealing ring 432. The floating powder is evenly discharged into the water through the sealing ring 432 and mixed with the water for floating powder recovery.

[0047] While the sealing disc 434 moves, it drives the telescopic shaft 433 and the limiting ring 435 to move, squeezing the spring 436. When no floating powder is collected, the spring 436 resets, driving the limiting ring 435, the telescopic shaft 433 and the sealing disc 434 to move and reset. The sealing disc 434 is movably engaged in the sealing ring 432, blocking the discharge port 421 and preventing water from flowing back into the feed cylinder 42 through the discharge port 421.

[0048] A crown gear 310 is fixedly sleeved on the outer side of the first straw 34. A first motor 3101 is fixedly installed on the outer wall of the flip frame 33 near the crown gear 310. The driving end of the first motor 3101 extends into the flip frame 33. A driving gear 3102 is fixedly installed on the driving end of the first motor 3101. The driving gear 3102 and the crown gear 310 are meshed and connected.

A protective cover 3103 is fixedly installed on the outer wall of the flip frame 33 near the first motor 3101. The first motor 3101 is located in the protective cover 3103.

[0049] A first worm gear 3104 is fixedly sleeved at one end of the flip shaft 331 near the L-shaped frame 32. A second motor 3105 is fixedly installed on the side of the L-shaped frame 32 near the first worm gear 3104. A first worm 3106 is fixedly installed at the drive end of the second motor 3105. The first worm 3106 and the first worm gear 3104 are meshed together. By controlling the second motor 3105 to drive the first worm 3106 to drive the first worm gear 3104 to rotate, the flip shaft 331 and the flip frame 33 are driven to flip, thereby changing the grinding disc 361, the first grinding paper 362, or... The positions of the sanding plate 371 and the second sanding paper 372 are such that when the sanding disc 361 and the first sanding paper 362 are close to the wall, the first sanding paper 362 can automatically sand a large area of ​​the wall. When the sanding plate 371 and the second sanding paper 372 are close to the wall, the second sanding paper 372 can automatically contact and sand the adjacent wall at the corner. When the sanding disc 361 and the first sanding paper 362 are facing upwards, the first sanding paper 362 can automatically sand a large area of ​​the upper wall.

By controlling the third motor 3108 to drive the second worm 3109 to drive the second worm gear 3107 to rotate, the first tube 321 and the L-shaped frame 32 are driven to rotate horizontally. This further changes the position of the sanding disc 361 and the first sanding paper 362 or the sanding plate 371 and the second sanding paper 372, so that the first sanding paper 362 and the second sanding paper 372 can automatically contact and sand the wall surface.

[0051] The drive mechanism 2 includes two symmetrically distributed mounting frames 21. The mounting frames 21 are fixedly installed on one side of the top of the device base 1. A first linear electric cylinder 22 is fixedly installed on the top and bottom of the mounting frames 21. An auxiliary seat 23 is fixedly installed on the drive end of the first linear electric cylinder 22. A second linear electric cylinder 24 is fixedly installed between the two auxiliary seats 23. The first linear electric cylinder 22 and the second linear electric cylinder 24 are vertically distributed. The drive end of the second linear electric cylinder 24 is fixedly installed on the first seat 31. In use, the first linear electric cylinder 22 is activated to drive the grinding mechanism 3 to move vertically, and the second linear electric cylinder 24 is activated to drive the grinding mechanism 3 to move horizontally, thereby driving the grinding mechanism 3 to automatically grind the wall surface without manual grinding, saving time and effort, and reducing safety hazards to the health of construction workers.

[0052] A magnetic ring 363 is attached to the side of the grinding disc 361 near the mounting bracket 36. The mounting bracket 36 and the magnetic ring 363 are magnetically attached. A locking protrusion 364 is integrally formed on the side of the mounting bracket 36 near the magnetic ring 363. The locking protrusion 364 is movably engaged with the magnetic ring 363 to magnetically attach the grinding disc 361, thereby facilitating the disassembly and replacement of the grinding disc 361.

[0053] The end of the flip frame 33 away from the first bearing 332 is threaded with a fixing bolt 373. The end thread of the fixing bolt 373 is threaded on the first fixing frame 37 to fix the first fixing frame 37, which facilitates the disassembly and replacement of the first fixing frame 37 and the grinding plate 371.

[0054] Working principle: When in use, the roller 5 is used to move the entire wall sanding device to the wall position.

[0055] Subsequently, according to the polishing requirements, the second motor 3105 is activated to drive the first worm gear 3106 to rotate the first worm wheel 3104, thereby driving the flipping shaft 331 and the flipping frame 33 to flip, thereby changing the position of the polishing disc 361, the first polishing paper 362 or the polishing plate 371 and the second polishing paper 372.

[0056] When the polishing disc 361 and the first polishing paper 362 are close to the wall, the telescopic cylinder 311 can be used to drive the polishing disc 361 and the first polishing paper 362 to move to one side of the wall, so that the annular brush 35 and the first polishing paper 362 are in contact with the wall. The first motor 3101 is activated to drive the drive gear 3102 to drive the crown gear 310 to rotate, thereby driving the first suction tube 34 to rotate at high speed, driving the connecting tube 341 and the dust hood 342 to rotate at high speed, which in turn drives the polishing disc 361 and the first polishing paper 362 to rotate at high speed. The first polishing paper 362 automatically polishes the wall. Since the annular brush 35 is in contact with the wall, the floating powder generated by the automatic polishing is left in the dust hood 342 for collection, preventing the floating powder from drifting in the building or falling on the ground.

[0057] At the same time, the first linear electric cylinder 22 is activated to drive the sanding mechanism 3 to move vertically, and the second linear electric cylinder 24 is activated to drive the sanding mechanism 3 to move horizontally, thereby driving the first sanding paper 362 in the sanding mechanism 3 to automatically sand the wall surface over a large area.

[0058] While automatically polishing a large area, the vacuum pump 44 is activated. The floating powder collected in the vacuum hood 342 is introduced into the feed pipe 412 through the connecting pipe 341, the first suction pipe 34, the L-shaped pipe 38, the second suction pipe 383, the third suction pipe 391, the first pipe 321, the fourth suction pipe 393, the vacuum hose 441, and the vacuum pump 44. The floating powder in the feed pipe 412 is introduced into the feed cylinder 42 and into multiple discharge ports 421.
