[0020] The present invention provides an automatic painting device for indoor walls. It has the following beneficial effects:

[0021] 1. The present invention adds and sets a wall cleaning mechanism to carry out systematic treatment before wall painting. First, the leveling function is used to effectively remove the protrusions and hollow parts of the wall to make the wall base flat. Then, deep cleaning is carried out to remove dust, stains and other impurities to create a clean base for subsequent painting. Then, attachment grinding is carried out to grind off residual old paint films, sticker marks and other attachments to further improve the smoothness and adhesion of the wall. This series of treatments cooperate with each other to greatly optimize the preliminary preparation work of the wall, which can not only ensure that the painting effect is uniform, firm and beautiful, but also effectively extend the service life of the painting layer, reduce the later maintenance cost and frequency, and improve the overall decoration quality and efficiency.

[0022] 2. The present invention adds and sets a bottom layer processing mechanism. After the wall surface is preliminarily treated by the cleaning mechanism, it can accurately carry out adhesion cleaning for residual attachments, thoroughly remove stubborn impurities, and avoid adverse effects on subsequent painting. After the adhesion cleaning is completed, atomization spraying bottom layer treatment is immediately carried out. The atomized liquid prepared according to the characteristics of the wall surface evenly covers the wall surface, effectively enhancing the water absorption and adhesion of the wall surface, making the subsequent painting paint easier to adhere and evenly distributed. This treatment method not only significantly improves the painting quality, reduces dripping, peeling and other phenomena, but also improves construction efficiency, reduces material loss, and lays a solid foundation for creating high-quality wall decoration.

[0023] 3. The present invention increases and sets a surface spraying mechanism. After the wall bottom layer treatment is completed, a simple drying is first performed to quickly evaporate the moisture of the bottom layer, so that the wall surface is in a suitable dryness, effectively shortening the overall construction period and preventing problems such as bubbling and mildew of the paint layer caused by residual moisture. The subsequent surface spraying treatment, with the help of automated spraying equipment, can evenly and delicately cover the wall with paint to ensure that the surface layer has consistent color and uniform texture. This method not only greatly enhances the decorative effect of the wall, making it more beautiful and artistic, but also enhances the bonding strength between the surface layer and the bottom layer, prolongs the service life of the wall decoration, and reduces the workload of later maintenance and repair.

[0024] 4. The present invention adds and sets a light and shadow guiding mechanism. After the wall is painted, the mechanism uses light and shadow technology and a specific painting template to project clear painting lines on the wall. This method greatly reduces the dependence on the professional skills of the staff. Ordinary people only need to trace the lines according to the projection to start painting. On the one hand, this processing method improves the painting efficiency of wall background paintings and reduces the time waste caused by manual drafting errors. On the other hand, it allows non-professionals to participate in complex wall painting work, broadens the participation group of artistic creation, and provides a convenient way for personalized wall decoration.

[0056] The function of the ball bearing 33 is to reduce the friction between the winding belt 35 and the surface of the mounting seat 32, thereby preventing the winding belt 35 from breaking during long-term use and extending the service life of the winding belt 35 and the light and shadow template 36 thereon.

[0057] The light and shadow guiding mechanism also includes a fixed seat 3, and a fixed seat 3 is arranged on both sides of the mounting seat 32, and the front sides of the fixed seats 3 are respectively connected to the corresponding positions of the inner walls of the mounting seat 2, and the middle part of the inner side of the fixed seat 3 is rotatably connected with a winding roller 34, and the two winding rollers 34 are connected by a winding belt 35, and a plurality of light and shadow templates 36 are equidistantly arranged in the middle part of the winding belt 35, and a driving motor 4 is arranged at the top of the fixed seat 3, and the output end of the driving motor 4 passes through the fixed seat 3 and is connected to the middle part of the winding roller 34 on the same side.

[0058] When the light and shadow guiding mechanism is started, the driving motor 14 on the fixed seat 3 is started first. When the driving motor 14 is started, it drives the winding roller 34 between the fixed seats 3 to rotate synchronously. The winding roller 34 rotates while winding the winding belt 35, and the winding roller 34 on the other side discharges the winding belt 35. When the light and shadow template 36 in front of the mounting seat 32 is adjusted to the template required by the staff, the driving motor 14 on the fixed seat 3 stops operating, and then the staff turns on the light source lamp 31 in the mounting seat 32. After the light source lamp 31 is turned on, the light emitted by the light source lamp 31 is projected onto the wall through the corresponding light and shadow template 36, thereby forming a line projection of the background painting. The staff only needs to trace the lines projected onto the wall and then fill in the colors to complete the drawing process of the background painting, thereby completing the light and shadow guiding operation of the background painting.
