Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a coating device for building exterior wall insulation construction. Background Technology

[0002] In the construction of building exterior wall insulation, substrate treatment and interface agent application are crucial steps to ensure the stability of the insulation system. Exterior wall substrates, after long-term exposure or initial construction, often have defects such as loose dust, gravel particles, localized protrusions, and residual mortar lumps. If not properly treated, these defects can lead to weak adhesion of the subsequent insulation material, resulting in hollow areas, detachment, and other quality problems, severely impacting the insulation effect and the building's lifespan. While some wall treatment devices exist in existing technologies, most are single-function devices (e.g., only capable of cleaning or painting) and lack adaptive adjustment structures for wall curvature and protrusions, failing to achieve integrated "cleaning-dust removal-painting" operations. Therefore, developing an automated painting device that integrates cleaning, dust removal, and painting functions and can adapt to complex wall shapes has become an urgent need to improve the efficiency and quality of exterior wall insulation construction. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a coating device for building exterior wall insulation construction, which solves the problems of limited functionality and lack of adaptive adjustment structure for wall curvature and protrusions in existing coating devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A coating device for building exterior wall insulation construction includes a base, a plurality of casters at the bottom of the base, two limiting posts opposite each other at the top of the base, the limiting posts being hollow inside and having an opening on one side opposite each other, a transmission screw being installed inside the limiting posts, a motor for driving the transmission screw being installed at the top of the limiting posts, a transmission slider being threadedly connected to the transmission screw, and an installation plate being installed on the side of the transmission slider away from the transmission screw.

[0006] The mounting plate is provided with multiple first springs at the upper end. The mounting plate is movably connected to the first connecting plate through the first springs. A brush is fixedly connected to the front side between the two first connecting plates. A scraper is provided below the brush.

[0007] The lower end of the mounting plate is provided with multiple second springs. The mounting plate is movably connected to the second connecting plate through the second springs. A roller is provided between the two second connecting plates.

[0008] A first fixing block is provided behind the first spring at the upper end of the mounting plate, and a material box is fixedly connected between the first fixing blocks. A second fixing block is provided behind the second spring at the lower end of the mounting plate, and a spraying mechanism is fixedly connected between the second fixing blocks. A connecting pipe is provided at the bottom of the material box, and the lower end of the connecting pipe is connected to the top of the spraying mechanism.

[0009] Preferably, a blower mechanism is provided behind the top brush of the scraper, and the air outlet of the blower mechanism is located between the brush and the scraper.

[0010] Preferably, the brush is a high-density nylon brush.

[0011] Preferably, the scraper is a rubber scraper.

[0012] Preferably, the base is also provided with a handle on top.

[0013] Compared with the prior art, the present invention provides the following beneficial effects:

[0014] By combining the brush, scraper, and blower mechanism in a front-to-back configuration, an integrated operation is achieved for cleaning floating dust, smoothing protrusions, and blowing away residual dust from the wall surface. The first and second springs, connecting the mounting plate to the first and second connecting plates respectively, allow the brush, scraper, and roller to automatically and elastically conform to the wall's curvature or protrusions, ensuring thorough cleaning and coating. The interconnected structure of the material box, connecting pipe, and spraying mechanism, combined with the roller's application action, enables continuous supply and uniform application of the insulation interface agent, resolving the issue of uneven coating thickness and improving the subsequent adhesion stability of the insulation material.

[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. 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.

[0020] Please see Figure 1 - Figure 3 This utility model provides a technical solution: a coating device for building exterior wall insulation construction, including a base 1, a plurality of universal wheels 2 are provided at the bottom of the base 1, two limiting posts 4 are provided opposite to each other at the top of the base 1, the limiting posts 4 are hollow inside and have an opening on one side opposite to each other, a transmission screw 6 is provided inside the limiting posts 4, a motor 5 for driving the transmission screw 6 is provided at the top of the limiting posts 4, a transmission slider 7 is threadedly connected to the transmission screw 6, and an installation plate 701 is provided on the side of the transmission slider 7 away from the transmission screw 6;

[0021] The upper end of the mounting plate 701 is provided with a plurality of first springs 16. The mounting plate 701 is movably connected to the first connecting plate 14 through the first springs 16. A brush 8 is fixedly connected to the front side between the two first connecting plates 14. A scraper 9 is provided below the brush 8.

[0022] The lower end of the mounting plate 701 is provided with a plurality of second springs 17. The mounting plate 701 is movably connected to the second connecting plate 15 through the second springs 17. A roller 10 is provided between the two second connecting plates 15.

[0023] A first fixing block 18 is provided behind the first spring 16 at the upper end of the mounting plate 701. A material box 12 is fixedly connected between the first fixing blocks 18. A second fixing block 19 is provided behind the second spring 17 at the lower end of the mounting plate 701. A spraying mechanism 13 is fixedly connected between the second fixing blocks 19. A connecting pipe 1201 is provided at the bottom of the material box 12. The lower end of the connecting pipe 1201 is connected to the top of the spraying mechanism 13.

[0024] Through the above technical solution, when the motor 5 drives the transmission screw 6 to rotate, the transmission slider 7 slides up and down along the opening of the limiting post 4, driving the mounting plate 701 and the connected functional components to rise and fall synchronously. The mounting plate 701 is connected to the first connecting plate 14 through the first spring 16, so that the brush 8 and scraper 9 have elastic buffering capacity: when the device moves to the protrusion of the wall, the first spring 16 is squeezed and contracted, driving the brush 8 and scraper 9 to adaptively retreat, avoiding damage to the components caused by rigid collision; when facing the concave or curved area of ​​the wall, the rebound force of the first spring 16 can ensure that the brush 8 fits tightly against the wall to clean the floating dust, and the scraper 9 scrapes off the remaining protrusions at the same time. Similarly, the second spring 17 connects the mounting plate 701 and the second connecting plate 15, so that the roller 10 always elastically presses against the wall surface, and works with the spraying mechanism 13 to achieve uniform application of the interface agent: the interface agent in the material box 12 is transported to the spraying mechanism 13 through the connecting pipe 1201, and after it is evenly sprayed out, the roller 10 moves with the device to smooth the interface agent.

[0025] This utility model provides a technical solution: a blower mechanism 11 is provided behind the top brush 8 of the scraper 9, and the air outlet 1101 of the blower mechanism 11 is located between the brush 8 and the scraper 9.

[0026] With the above technical solution, the air outlet 1101 is located between the brush 8 and the scraper 9. After the brush 8 performs preliminary dust removal on the wall surface, the blower mechanism 11 blows out a directional airflow through the air outlet 1101 to remove the dust raised by the brush 8 in real time. It can also blow away the residue scraped off by the scraper 9 from the board surface, providing a clean base layer for subsequent interface agent application and avoiding the decrease in adhesion caused by dust isolation.

[0027] This utility model provides a technical solution: the brush 8 is a high-density nylon brush, and the scraper 9 is a rubber scraper.

[0028] Through the above technical solutions, brush 8 uses high-density nylon bristles. The dense nylon bristles can penetrate deep into the small crevices of the wall to remove attached dust, powdery impurities, and residual paint debris, avoiding the problem of missed areas caused by sparse bristles. The nylon bristles have moderate elasticity, and under the cushioning of the first spring 16, they can generate sufficient friction to remove impurities without scratching concrete, brick, or other base surfaces. The scraper 9 is made of natural rubber. The flexibility of rubber can adapt to the deformation of the wall surface. Under the pressure of the second spring 17, it closely conforms to the curvature of the wall surface, ensuring that hard lumps and mortar protrusions are thoroughly scraped off, while avoiding damage to the wall base caused by the rigid contact of traditional metal scrapers.

[0029] The working principle of this utility model is as follows: During operation, the device is pushed to the wall surface to be constructed by the universal wheels 2 at the bottom of the base 1, and the braking structure of the universal wheels 2 is locked to fix the device. The motor 5 at the top of the limiting post 4 is started, and the motor 5 drives the transmission screw 6 to rotate, which drives the transmission slider 7 to slide up and down along the opening of the limiting post 4, thereby causing the mounting plate 701 and the connected brush 8, scraper 9, roller 10 and other components to rise and fall synchronously, adapting to the construction needs of walls of different heights. As the mounting plate 701 moves, the front brush 8 is tightly attached to the wall surface under the elastic action of the first spring 16, and uses the friction of the dense nylon filaments to sweep away the floating dust and powder impurities in the gaps of the wall surface; the blower mechanism 11 behind the brush 8 is started at the same time, blowing out a directional airflow through the flat air outlet 1101 located between the brush 8 and the scraper 9, cleaning the residual floating dust on the wall surface, and also cleaning the residue left on the scraper 9. The rubber scraper 9, cushioned by the first spring 16, adapts to the curvature of the wall surface and scrapes away any remaining solid protrusions (such as mortar blocks or pebbles) on the wall surface, following the blower mechanism 11, ensuring that the flatness of the wall surface meets the construction requirements.

[0030] The interface agent in the material box 12 is transported to the spraying mechanism 13 located behind the roller 10 via the connecting pipe 1201. The spraying mechanism 13 sprays the paint evenly onto the outer surface of the roller 10. The roller 10 is elastically pressed against the wall under the pressure of the second spring 17. As the device moves, the roller 10 rotates (due to friction with the wall), evenly transferring the interface agent adhering to the surface and coating it onto the wall.

[0031] 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.
