[0024] Please see Figures 1 to 4 This utility model provides a technical solution:
[0025] Example 1: An automatic wall paint sanding device, comprising: a mounting base 1.
[0026] Specifically, multiple symmetrically arranged self-locking casters 2 are fixedly connected to the lower side of the mounting base 1. A positioning rod 11 for positioning the mounting base 1 is slidably arranged at one end of the mounting base 1. A baffle 12 for limiting the sliding of the positioning rod 11 is slidably connected to one side of the mounting base 1. Two symmetrically arranged uprights 3 are fixedly connected to the side of the mounting base 1. One end of one upright 3 is connected to a lead screw 4 driven by a motor 41. A connecting rod 5 is threaded onto the side of the lead screw 4. One end of the connecting rod 5 is slidably connected to the mounting base 1, and a mounting plate 6 is slidably connected to the side of the connecting rod 5. One side of the mounting plate 6 is fixedly connected to... A second motor 7 is connected, with one end of the second motor 7 fixedly connected to a grinding wheel 8 for grinding the paint on the inner wall. The grinding surface of the grinding wheel 8 is flush with one side of the positioning rod 11. A hydraulic cylinder 9 is fixedly connected to one side of the connecting rod 5, and the shaft of the hydraulic cylinder 9 is fixedly connected to the mounting plate 6. In actual implementation, the positioning rod 11 is first slid towards the end of the grinding wheel 8, and then the sliding baffle 12 locks the positioning rod 11, fixing its position. Next, the mounting base 1 is pushed towards the wall until the positioning rod 11 is in contact with the wall, and then each self-locking caster 2 is locked, thus fixing the mounting base 1 as a whole. Then, slide the baffle 12 to release the restriction on the positioning rod 11. Next, slide the positioning rod 11 away from the wall, and then lower the baffle 12 to lock the positioning rod 11, thus preventing the positioning rod 11 from affecting the grinding wheel 8's grinding of the lower end of the wall. When the mounting base 1 is fixed, the grinding wheel 8 is already in contact with the wall's paint layer. Then, start the second motor 7 to make the grinding wheel 8 start rotating and grinding the wall's paint layer. At this time, the hydraulic cylinder 9 will also slowly push the mounting plate 6 to slide horizontally, so that the grinding wheel 8 automatically grinds the wall during the sliding process. After the mounting plate 6 slides to the other end of the mounting base 1, the first motor 4... 1 drives the lead screw 4 to rotate, then controls the connecting rod 5 to slide down, thereby causing the mounting plate 6, the second motor 7, the grinding wheel 8, and the hydraulic cylinder 9 to slide down to a suitable height. Then, the hydraulic cylinder 9 will drive the mounting plate 6 to slide back to its original position, thereby grinding the areas adjacent to the already ground area. This process is repeated until the entire wall surface is ground. At the same time, when the grinding wheel 8 is at both ends of the mounting base 1, the outer ring of the grinding wheel 8 will be outside the end of the mounting base 1, thus ensuring that the grinding wheel 8 can also grind the corners of the wall well. This is not only very convenient, but also ensures the overall flatness of the wall coating and improves the aesthetics of the wall.
[0027] To ensure the stability of the positioning rod 11 and to better fix the positioning rod 11, the positioning rod 11 of this application is set in a "U" shape. This allows the positioning rod 11 to slide more stably and also allows the positioning rod 11 to better position the mounting base 1. The baffle 12 is set in an "L" shape, which can ensure the sliding of the baffle 12 while allowing the baffle 12 to better restrict the positioning rod 11.
[0028] To facilitate the installation of the positioning rod 11 and the baffle 12, a polygonal fixing rod 13 is fixedly connected to one side of the mounting base 1 of this application. The baffle 12 and the fixing rod 13 are slidably connected, and a limit block 14 is fixedly connected to one end of the fixing rod 13. This ensures that the baffle 12 can slide while preventing the baffle 12 from rotating. At the same time, the limit block 14 can prevent the baffle 12 from sliding off the fixing rod 13. One end of the mounting base 1 is provided with an insertion hole 16 for the positioning rod 11 to slide into, which facilitates the installation of the mounting base 1.
[0029] To facilitate the installation of the connecting rod 5, both ends of the connecting rod 5 in this application are fixedly connected to sliders 51 in the shape of "T". The two sliders 51 are slidably connected to the two uprights 3 respectively. One slider 51 has a threaded hole 53 for the lead screw 4 to be threaded into. The slider 51 and the threaded hole 53 can facilitate the lead screw 4 to control the connecting rod 5 to slide up and down. The other slider 51 has a sliding hole 54 on one side. A guide rod 15 is fixedly connected to one side of the mounting base 1 and slidably inserted into the sliding hole 54. The sliding hole 54 and the guide rod 15 can better restrict the rotation of the connecting rod 5 and better constrain the movement trajectory of the connecting rod 5.
[0030] To facilitate the installation of the mounting plate 6, the connecting rod 5 of this application is designed as a polygon, which can restrict the rotation of the mounting plate 6. One end of the mounting plate 6 is provided with a mounting hole 62 for the connecting rod 5 to slide into, which facilitates the sliding insertion of the connecting rod 5.
[0031] To facilitate the installation of the hydraulic cylinder 9, a connecting plate 52 is fixedly connected to one side of the slider 51 of this application. The hydraulic cylinder 9 and the connecting plate 52 are fixedly connected. The connecting plate 52 can provide a mounting platform for the hydraulic cylinder 9, allowing the hydraulic cylinder 9 to better contact the mounting plate 6. A protruding plate 61 is fixedly connected to one side of the mounting plate 6. The protruding plate 61 is fixedly connected to the shaft of the hydraulic cylinder 9. The protruding plate 61 allows the hydraulic cylinder 9 to better control the reciprocating motion of the mounting plate 6 in the horizontal direction, thereby facilitating the reciprocating sliding of the grinding wheel 8.
[0032] 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.
