Description

Technical Field

[0001] This utility model relates to the field of wall decoration technology, specifically to a wall polishing device. Background Technology

[0002] Wall sanding is a process performed after putty application to improve the smoothness and finish of the wall surface. Sanding eliminates roughness and unevenness, enhancing the wall's smoothness and texture, thereby improving the adhesion of paint or wallpaper. It not only affects the final smoothness of the wall but is also an important means of correcting minor imperfections during wall decoration.

[0003] Existing patent publication (announcement) numbers CN213592443U and CN222371126U disclose a wall sanding device and a decorative wall sanding equipment, respectively. Both of these methods use a sanding structure that moves up and down to achieve the sanding work, resulting in a very limited sanding surface. However, in actual sanding operations, after sanding the wall surface up and down, it is necessary to move the device left and right to sand other wall areas. This requires repositioning and adjusting the sanding position, making the entire wall sanding process very cumbersome. Therefore, we have proposed a decorative wall sanding device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a wall sanding device to solve the problems currently found in the market as described in the background.

[0024] 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.

[0025] Please see Figure 1-8 The present invention provides a technical solution: a wall polishing device, including a base 1, a caster wheel 2 installed on the lower side of the base 1, a leveling support foot 3 on the base 1, a handle 4 fixed on the upper rear side of the base 1, and an equipment box 6 on the upper side of the base 1.

[0026] Furthermore, there are three leveling feet 3 on the base 1, and the three leveling feet 3 are distributed in an isosceles triangle, which makes it easy to quickly determine the horizontal position of the base 1 with three fulcrums. The leveling feet 3 are threadedly connected to the base 1, and the lower end of the leveling feet 3 has a conical structure, which facilitates the operation and use of the leveling feet 3 and improves the efficiency of leveling work.

[0027] Furthermore, the equipment box 6 contains a portable battery and a vacuum cleaner. The vacuum cleaner is connected to the grinding cover 17 through the vacuum pipe 19. A control switch 5 is installed on the handle 4. The portable battery is electrically connected to motor 9, motor 20 and motor 3 26 through the control switch 5. The control switch 5 is used to control the operation of motor 9, motor 20 and motor 3 26 to ensure the normal working state of the device.

[0028] A screw 7 and a stabilizing rod 8 are mounted on the upper side of the base 1 via a bracket. The screw 7 is connected to a motor 9 via a sprocket and a chain, and the motor 9 is mounted on the bracket. A vertical moving body 10 is sleeved on the screw 7 and the stabilizing rod 8. A rotating seat 11 is rotatably connected to the outside of the vertical moving body 10. The rotating seat 11 is fixed in position on the vertical moving body 10 by a positioning bolt 12.

[0029] Furthermore, the positioning bolt 12 is threadedly connected to the rotating seat 11, and the front end of the positioning bolt 12 is embedded in the vertical moving body 10 to ensure a stable connection between the rotating seat 11 and the vertical moving body 10. The vertical moving body 10 has four holes that are symmetrically opened and closed at the center and are aligned with the positioning bolt 12, which can directly position the horizontal moving seat 13 in a horizontal or vertical state, making it convenient to adjust it.

[0030] A transverse moving seat 13 is fixed to the outside of the rotating seat 11. A screw 14, a stabilizer 15, and a motor 26 are installed on the transverse moving seat 13. The stabilizer 15 is driven to rotate on the transverse moving seat 13 by the motor 26. A transverse moving body 16 is sleeved on the screw 14 and the stabilizer 15.

[0031] A grinding cover 17 is mounted on the front side of the transversely moving main body 16 via a bearing. A dustproof edge 21 is fixed to the edge of the grinding cover 17. A second motor 20 is installed inside the front side of the transversely moving main body 16. A grinding disc 18 is installed on the output end of the second motor 20. The grinding disc 18 is located inside the grinding cover 17. A fixing plate 22 is fixedly installed on the outer edge of the grinding disc 18 via a fixing bolt 23. The fixing plate 22 is provided with longitudinal bristles 24 and transverse bristles 25.

[0032] Furthermore, the eccentric fixed connection between the polishing disc 18 and the output end of the second motor 20 enables large-area polishing work with a small-volume polishing disc 18, while leaving space for dust suction and ventilation, effectively improving the dust removal effect. The fixing plate 22 is located at the farthest position between itself and the output end of the second motor 20. The outer ends of the longitudinal bristles 24 on the fixing plate 22 contact the inner side of the polishing cover 17, and the outer ends of the transverse bristles 25 on the fixing plate 22 protrude from the outer side of the polishing disc 18, ensuring cleaning of the inner side of the polishing cover 17 and the wall polishing area, thereby ensuring the quality of dust suction work.

[0033] Specifically, when using this wall sanding device, first push the device with handle 4, and move the device to the vicinity of the wall surface via the casters 2 on the base 1. Then rotate the leveling feet 3 so that the three leveling feet 3 support the base 1, and adjust the horizontal working position of the device through the three leveling feet 3 to ensure normal sanding and smoothing of the wall surface.

[0034] Then the horizontal moving seat 13 is rotated to the horizontal state by the rotating seat 11, and the vertical moving body 10 and the rotating seat 11 are fixed by the positioning bolt 12 to ensure the stable working state of the horizontal moving seat 13. In this state, the grinding disc 18 inside the grinding cover 17 is in contact with the wall surface.

[0035] Then, by controlling the switch 5 on the handle 4, the motor 3 26 is powered on and starts working. The motor 3 26 drives the screw 2 14 to rotate, and the horizontal moving body 16 moves steadily left and right in the horizontal moving seat 13. Simultaneously, the motor 2 20 is started, driving the grinding disc 18 to rotate. The working position of the grinding disc 18 will follow the horizontal moving body 16 to move left and right on the horizontal moving seat 13, and the grinding disc 18 can then perform grinding work on the wall surface.

[0036] During the sanding process, the dust inside the sanding hood 17 is sucked away by the vacuum cleaner in the equipment box 6 through the vacuum pipe 19. The edge of the sanding hood 17 contacts the wall through the dust isolation edge 21, which can both prevent the dust inside the sanding hood 17 from flying and allow ventilation, ensuring that the vacuuming work can proceed normally.

[0037] Furthermore, during the sanding process, the eccentric rotation of the sanding disc 18 can sweep the dust on the wall and the inner wall of the sanding cover 17 by the longitudinal bristles 24 and the transverse bristles 25 on the fixed plate 22, so as to facilitate efficient dust blowing.

[0038] After the grinding disc 18 has completed the left and right grinding work at the same height, the screw 7 can be rotated by the motor 9 to move the vertical moving body 10 up and down. This can change the up and down position of the grinding disc 18, allowing the grinding disc 18 to move left and right at different heights, thereby completing the grinding work of the wall surface in one go and effectively improving the efficiency of wall grinding work.

[0039] The above describes the working process of the device, and all content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
