Description

Technical Field

[0001] This utility model relates to the field of decoration and renovation, and in particular to a wall sanding device for decoration and renovation. Background Technology

[0002] Wall sanding is a very important step in the renovation process, and it brings the following three significant benefits:

[0003] Improving latex paint adhesion: Sanding makes the wall surface more porous, allowing the primer to absorb and penetrate better, thus enhancing the latex paint's adhesion. This allows the putty layer and latex paint to bond more tightly.

[0004] Reduce the possibility of peeling. A smoother, more even wall surface is achieved through sanding. During the putty application process, minor imperfections are inevitable. Sanding removes these imperfections, resulting in a smoother, more even, and finer wall surface. Such a wall not only looks more aesthetically pleasing but also facilitates subsequent painting.

[0005] To avoid color variations, the sanded putty layer has a more uniform and consistent structure, which prevents localized color differences in latex paint caused by variations in surface structure. This results in a more even and aesthetically pleasing color across the entire wall.

[0006] Currently, most wall sanding methods involve manual hand-held wall sanders. During the sanding process, the sander needs to be held for a long time, which puts a great strain on the human body. The uniformity of sanding depends on the operator's experience and cannot be guaranteed. In addition, a lot of dust is generated during the sanding process, which is harmful to the health of the personnel. Utility Model Content

[0007] To overcome the shortcomings of the existing technology, this utility model provides a decorative wall sanding device. The end of the sanding head away from the blade is provided with an extension sleeve. The extension sleeve can reduce the amount of dust generated during wall sanding that enters between the motor or drive gear and the rotating platform, thus affecting the life of the motor or the operation of the drive gear. The radius difference between the sanding head and the rotating platform is greater than the thickness of the outer frame sidewall. Thus, when the device is fixed, the maximum sanding range of the sanding head exceeds the width of the outer frame, avoiding the influence of the outer frame and preventing the edges of the wall from being sanded.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a decorative wall sanding device, including a sanding structure, the sanding structure including a sanding part, the sanding part including a sanding head, the sanding head being provided with not less than three blades for wall sanding, the sanding head being coaxially mounted on a rotating platform, the sanding head being fixedly connected to the rotating platform, the rotating platform being disc-shaped, the rotating platform having teeth on its circumferential wall, the rotating platform meshing with a drive gear through the teeth, the drive gear being mounted on the output end of a motor, the end of the sanding head away from the blades being provided with an extension sleeve, the extension sleeve extending to more than one-third of the position of the motor, the center position of the rotating platform being provided with a through hole, the through hole penetrating the rotating platform, a dust suction pipe being installed in the through hole, the end of the dust suction pipe near the sanding head having a wide-mouth design, and the end of the dust suction pipe away from the sanding head being connected to an air suction pump.

[0013] Furthermore, the bolts are mounted on the base frame via bearings, the base frame comprising an outer frame, the bottom of which is provided with movable rollers.

[0014] Furthermore, a frame is installed on the second carriage, and a spherical sleeve is provided at one end of the frame away from the second carriage. A spherical roller is installed inside the spherical sleeve and the spherical roller is in contact with the outer frame. A sliding rod is provided around the spherical sleeve. One end of the sliding rod is fixedly installed on the frame, and the other end of the sliding rod is a spherical head. The sliding rod contacts the outer frame through the spherical head.

[0015] Furthermore, the outer frame is provided with a guide groove, and the bottom of the first carriage is provided with a support frame, and the first carriage is mounted on the guide groove through the support frame.

[0016] Furthermore, the grinding head can extend beyond the outer frame, and the radius difference between the grinding head and the rotating platform is greater than the thickness of the sidewall of the outer frame.

[0017] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0018] 1. This device can drive the rotating platform to rotate through the drive gear, so that the grinding head can rotate. The grinding head achieves the grinding function of the wall by contacting the wall surface. An extension sleeve is provided at the end of the grinding head away from the blade.

[0032] Example:

[0033] Combination Figures 1-9As shown, this utility model provides a decorative wall sanding device, including a sanding structure 3, which includes a sanding part 32. The sanding part 32 includes a sanding head 329, which is equipped with at least three blades for wall sanding. The sanding head 329 has a disc structure, and the blades are made of carbide. The sanding head 329 is coaxially mounted on a rotating platform 328, and the sanding head 329 is fixedly connected to the rotating platform 328. The rotating platform 328 is disc-shaped, and teeth are provided on its circumferential wall. The rotating platform 328 meshes with a drive gear 327 through the teeth. The drive gear 327 is installed at the output end of a motor 326. By starting the motor 326, the rotating platform 328 can be rotated through the drive gear 327, causing the sanding head 329 to rotate. The wall polishing function is achieved by contacting the wall surface. The end of the polishing head 329 away from the blade is provided with an extension sleeve, which extends to more than one-third of the position of the motor 326. The extension sleeve can reduce the amount of dust generated during wall polishing that enters between the motor 326 or the drive gear 327 and the rotating platform 328, thus reducing the impact on the life of the motor 326 or the operation of the drive gear 327. A through hole 323 is provided at the center of the rotating platform 328, which runs through the rotating platform 328. A dust suction pipe 33 is installed in the through hole 323. The end of the dust suction pipe 33 near the polishing head 329 has a wide-mouth design, and the end of the dust suction pipe 33 away from the polishing head 329 is connected to an air suction pump 34. The air suction pump 34 can suck in the dust generated when the polishing head polishes the wall, avoiding the generation of a large amount of dust during operation.

[0034] The grinding part 32 is mounted on the guide structure 31, which includes a frame 311. The frame 311 is U-shaped, and a guide rod 312 is installed inside the frame 311. A sliding frame 321 is mounted on the guide rod 312. The sliding frame 321 is provided with a sliding hole 322 that fits onto the guide rod 312. To ensure the stability of the sliding frame 321's movement, a sliding groove 324 is provided on the sliding frame 321. The sliding groove 324 is a through groove, and the width of the sliding frame 321 is greater than the width of the frame 311. The sliding frame 321 is mounted on the frame 311 through the sliding groove 324. In this way, the stability of the sliding frame 321's movement can be ensured while the sliding frame 321 slides freely on the guide rod 312.

[0035] The through hole 323 passes through the sliding frame 321, which ensures the insertion of the suction pipe 33. To prevent the suction pipe 33 from interfering with the movement of the sliding frame 321 when it moves, the guide rod 312 is provided with a clearance groove 313 for the movement of the suction pipe 33.

[0036] The sliding frame 321 is provided with a groove, and a friction roller 325 is installed in the groove. The friction roller 325 is equipped with a matching motor, which is controlled by an external control module. The friction roller 325 is in contact with the guide rod 312. With this configuration, the rotation of the friction roller 325 can drive the sliding frame 321 to move on the guide rod 312.

[0037] The frame 311 is fixedly mounted on the drive structure 2. The drive structure 2 includes a bolt 21, on which a first slide 22 is threadedly mounted. The bolt 21 is equipped with a matching motor, which is controlled by an external control module. The rotation of the bolt 21 drives the first slide 22 to move along the bolt 21. Slide rails 24 are provided on both sides of the first slide 22. A second slide 27 is mounted on the first slide 22 through the slide rails 24. The second slide 27 can slide freely on the first slide 22. A friction belt 25 is provided on the upper surface of the first slide 22. A friction wheel 26 that cooperates with the friction belt 25 is mounted on the second slide 27 through a shaft. The friction wheel 26 is equipped with a matching motor, which is controlled by an external control module. The rotation of the friction wheel 26 and its cooperation with the friction belt 25 enable the second slide 27 to slide on the first slide 22. The movement of the first slide 22 increases the grinding range of the grinding head 329, and the movement of the second slide 27 allows for the adjustment of the grinding depth.

[0038] The bolt 21 is mounted on the base frame 1 via a bearing. The base frame 1 includes an outer frame 11, which is U-shaped. A movable roller 12 is provided at the bottom of the outer frame 11. The movable roller 12 can be used to move the device easily during operation. The movable roller 12 is equipped with a braking system, which can fix the device during operation.

[0039] A frame 311 is mounted on the second slide 27. This configuration allows for adjustment of the grinding position of the grinding head 329. To prevent tilting during frame 311 movement, a spherical sleeve 314 is provided at the end of frame 311 away from the second slide 27. A spherical roller 315 is installed inside the spherical sleeve 314 and can rotate freely within it. The spherical roller 315 contacts the outer frame 11. The rotation of the spherical roller 315 reduces the friction between frame 311 and outer frame 11 during movement. Slide rods 316 are provided around the spherical sleeve 314. One end of the slide rod 316 is fixedly mounted on frame 311, and the other end of the slide rod 316 is a spherical head. The slide rod 316 contacts the outer frame 11 through the spherical head, thus preventing tilting during frame 311 movement.

[0040] The outer frame 11 is provided with a guide groove 13, and the bottom of the first slide 22 is provided with a support frame 23. The first slide 22 is mounted on the guide groove 13 through the support frame 23. This arrangement can support the first slide 22 and prevent the support frame 23 from tilting due to uneven force.

[0041] The grinding head 329 can extend beyond the outer frame 11, thus preventing the outer frame 11 from affecting the operation of the grinding head. The radius difference between the grinding head 329 and the rotating platform 328 is greater than the thickness of the side wall of the outer frame 11. Thus, when the device is fixed, the maximum grinding range of the grinding head 329 exceeds the width of the outer frame 11, avoiding the influence of the outer frame 11 and preventing the edges on both sides of the wall from being unable to be ground.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
