Description

Technical Field

[0001] This utility model relates to the field of building exterior wall decoration technology, specifically a leveling and grinding device for building exterior wall decoration. Background Technology

[0002] Building exterior wall finishes refer to one or more layers of materials used to beautify, protect, and enhance the functionality of a building's exterior walls. Paint is one of the most common exterior wall decoration materials, including latex paint, real stone paint, and imitation stone paint. These offer a rich selection of colors and textures, simulating various stone and metal effects, while also possessing good weather resistance and waterproofing. Natural stone, such as granite and marble, is favored for its unique textures and colors. Artificial stone, synthesized artificially, mimics the appearance and texture of natural stone, offering advantages such as light weight, high strength, and corrosion resistance. Metal sheets, such as aluminum and copper, are widely used in modern architecture due to their unique luster and texture. They are not only aesthetically pleasing but also possess good durability and plasticity. Glass curtain walls, with their transparency and lightness, have become a hallmark of modern architecture. Through different processing techniques and design methods, glass curtain walls can present rich visual effects and functionalities. Ceramic exterior wall tiles are characterized by their hardness, wear resistance, and acid and alkali resistance, while also offering a rich variety of colors and patterns, suitable for various architectural styles.

[0003] In the existing technology, the exterior wall decoration surface of buildings is generally made of artificial stone. In actual installation, operators need to fill and fix the joints with cement. After complete curing, it needs to be ground and leveled. In order to facilitate the process and reduce the impact of dust on operators, we propose a leveling and grinding device for the exterior wall decoration surface of buildings. Utility Model Content

[0004] The purpose of this utility model is to provide a leveling and grinding device for the exterior wall decorative surface of a building, so as to solve the problems existing in the prior art mentioned in the background art.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A surface leveling and grinding device for building exterior walls includes a device box 3, a grinding motor housed inside the device box 3, a rotating column 2 fixedly connected to the end of the output shaft of the grinding motor, a grinding wheel 11 fixedly connected to the front end of the rotating column 2, a cover plate 1 covering the outer side of the grinding wheel 11, a handle 4 fixedly connected to the lower end of the device box 3, a base plate 5 fixedly connected to the lower end of the handle 4, a connecting plate 8 provided on the front side of the base plate 5, a slot penetrating the side wall of the connecting plate 8, and a dust collection device engaged in the slot. The dust collection device includes a slotted assembly. The vacuum pump box 9 is located in the slot. The vacuum pump box 9 contains a vacuum pump and a dust box at the input end of the vacuum pump. A dust pipe 10 is fixedly connected to the other side of the dust box. A connecting groove is provided through the lower end of the cover plate 1 at the corresponding position. The other end of the dust pipe 10 is connected to the connecting groove. An annular magnetic sheet is provided on the inner wall of the slot, and a corresponding metal sheet is provided on the outer wall of the vacuum pump box 9. These can be used to fix the position of the vacuum pump box 9. The vacuum pump box 9 is a box with a built-in vacuum pump and a dust box for the vacuum pump is provided inside for easy cleaning.

[0021] The base plate 5 has a threaded groove through its side wall, and an adjustment device is threaded into the threaded groove. The adjustment device includes an adjustment screw 6 threaded into the threaded groove, and a rotating seat 12 is rotatably connected to the tail end of the adjustment screw 6. A motion groove is through its side wall at the corresponding position of the connecting plate 8. The rotating seat 12 is located in the motion groove. The side wall of the rotating seat 12 located in the motion groove is elastically connected to the inner wall of the motion groove by a spring 13.

[0022] Specifically, a guide device is provided between the base plate 5 and the connecting plate 8. The guide device includes two guide posts 7 fixedly connected to the side wall of the connecting plate 8. Two guide grooves are provided through the side wall of the base plate 5 at the corresponding positions, and the two guide posts 7 are slidably connected in the two guide grooves respectively.

[0023] It is worth mentioning that the front side wall of the cover plate 1 protrudes from the corresponding side wall of the connecting plate 8. When the cover plate 1 is in contact with the wall, the connecting plate 8 will not contact the wall and will not affect the normal docking and use of the cover plate 1.

[0024] In this invention, the operator rotates the adjusting screw 6, which, through the rotating seat 12 and the spring 13, drives the connecting plate 8 to move, thereby moving the cover plate 1 and changing the relative position of the grinding wheel 11 and the cover plate 1 to a suitable position. When grinding, the operator holds the device and places the cover plate 1 against the protruding part to be ground, then presses the device forward. The spring 13 at the corresponding position will compress and deform, causing the grinding wheel 11 designed on the inner side of the cover plate 1 to move forward and contact the protruding surface to perform the grinding operation. The debris generated by grinding is blocked by the cover plate 1 and then absorbed by the suction generated at the dust pipe 10, thus entering the dust pump box 9. After grinding, the operator can directly move the cover plate 1 without any debris spilling.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
