[0005] The purpose of this utility model is to provide an exterior wall painting device for building construction in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An exterior wall painting device for building construction includes a mounting frame and a painting unit. A material conveying unit, a material receiving unit and an adjusting unit are fixedly installed on the mounting frame. A connecting seat is fixedly installed on the adjusting unit. The painting unit is rotatably installed on the mounting frame.

[0008] The painting unit includes mounting bases, support wheels, and flexible painting rollers. The mounting bases are fixedly mounted on both ends of the mounting frame by bolts. Support bases are rotatably mounted on the opposite sides of the two mounting bases. A strut and a placement groove are fixedly arranged between the opposite sides of the two support bases. Flexible components are fixedly arranged on the struts. The flexible components are fixedly connected to the support wheels. The support wheels are arranged in a row and sleeved on the struts. The flexible painting roller is sleeved on the support wheels. The flexible painting roller is connected to the support wheels through a traction component. Both ends of the flexible painting roller are fixedly mounted in the placement grooves by bolts.

[0009] Furthermore, the elastic component includes damping rods, which are fixedly arranged on the support rods. The telescopic ends of the damping rods are fixedly connected to the inner side of the support wheel, and springs are sleeved on the damping rods.

[0010] Furthermore, the traction assembly includes a locking block and a locking slot. The locking block is arranged on the inner wall of the elastic paint roller, and the locking block is slidably installed in the locking slot. The locking slot is arranged on the outer surface of the support wheel.

[0011] Furthermore, the material conveying unit includes a guide pipe, which is fixedly installed on the upper surface of the mounting frame.

[0028] like Figures 1-7As shown, an exterior wall painting device for building construction includes a mounting frame 1 and a painting unit. A material conveying unit, a material receiving unit, and an adjusting unit are fixedly installed on the mounting frame 1. A connecting seat 2 is fixedly installed on the adjusting unit. The painting unit is rotatably mounted on the mounting frame 1. The connecting seat 2 facilitates connection of the entire painting device to an external lifting mechanism, enabling painting at different heights. The adjusting unit adjusts the connection length between the mounting frame 1 and the connecting seat 2, thereby facilitating adjustment of the painting angle of the painting unit. The painting unit paints the wall. During the painting process, the material conveying unit automatically feeds the painting material, ensuring continuous painting and improving efficiency. Simultaneously, the material receiving unit collects excess painting material, reducing waste and pollution.

[0029] like Figure 1 , Figures 3-7As shown, the painting unit includes a mounting base 301, support wheels 306, and an elastic painting roller 308. The mounting base 301 is fixedly mounted on both ends of the mounting frame 1 by bolts. Support seats 303 are rotatably mounted on the opposite sides of the two mounting bases 301. A support rod 302 and a placement groove 307 are fixedly arranged between the opposite sides of the two support seats 303. Elastic components are fixedly arranged on the support rod 302. The elastic components are fixedly connected to the support wheels 306. The support wheels 306 are arranged in a row and sleeved on the support rod 302. The elastic painting roller 308 is sleeved on the support wheels 306. The elastic painting roller 308 is connected to the support wheels 306 through a traction component. The two ends of the elastic painting roller 308 are fixedly mounted by bolts. The mounting base 301, installed in the placement slot 307 and fixed to the mounting frame 1 by bolts, allows for quick disassembly of the painting unit, effectively improving the convenience of replacing the flexible painting roller 308. A traction component connects the flexible painting roller 308 and the support wheel 306 together. The support base 303, placement slot 307, and bolts secure the flexible painting roller 308, preventing it from slipping. The mounting frame 1 uses the mounting base 301, support base 303, and support rod 302 to place the support wheel 306 and the flexible painting roller 308 onto the wall. The material conveying unit sprays the painting paint onto the flexible painting roller 308, and the support wheel 306 and the flexible painting roller 308 move along the wall... The elastic component moves along the wall, providing elastic support to the elastic paint roller 308 via the support wheel 306. The elastic paint roller 308 then applies the paint to the wall. When encountering a protrusion on the wall during application, the protrusion pushes the support wheel 306 in the opposite direction via the elastic paint roller 308, causing the elastic paint roller 308 to deform. The elastic paint roller 308 then compresses the elastic component via the support wheel 306. This increases the force applied to the elastic paint roller 308 by the elastic component, ensuring the elastic paint roller 308 fits tightly against the protrusion on the wall. This compression allows the paint material to move, effectively preventing paint material accumulation. Simultaneously, the elastic paint roller 308 also moves along the wall at other locations. Since the roller 308 is not subjected to the reverse force of the protrusion, it continues to paint under the support of the elastic component. When it encounters a depression in the wall, the elastic component, supported by the support wheel 306, drives the elastic paint roller 308 into the depression for painting, effectively avoiding missed spots and ensuring the uniformity and quality of the paint application. The elastic paint roller 308 can better conform to the wall surface, improving the adhesion of the paint and reducing paint waste. The independent adjustment of the support wheel 306 combined with the deformation of the elastic paint roller 308 allows the device to adapt to various complex wall surface irregularities, avoiding the impact of uneven wall surfaces on the painting quality and ensuring high-quality painting in different locations.

[0030] like Figure 3 , Figure 4 , Figure 6 As shown, the elastic component includes a damping rod 304, which is fixedly arranged on the support rod 302. The telescopic end of the damping rod 304 is fixedly connected to the inner side of the support wheel 306. A spring 305 is sleeved on the damping rod 304. The damping rod 304 and the spring 305 provide elastic support for the support wheel 306, so that the support wheel 306 can apply force to the elastic painting roller 308, allowing the elastic painting roller 308 to better conform to the wall for painting and ensuring the quality of painting.

[0031] like Figure 4 As shown, the traction assembly includes a locking block 309 and a locking groove 310. The locking block 309 is arranged on the inner wall of the elastic painting roller 308 and is slidably installed in the locking groove 310. The locking groove 310 is arranged on the outer surface of the support wheel 306. The elastic painting roller 308 is fixed to the support wheel 306 by the locking block 309 and the locking groove 310. During the painting operation, the support wheel 306 drives the elastic painting roller 308 to rotate through the locking block 309 and the locking groove 310 to avoid slippage and make different parts of the elastic painting roller 308 contact the wall for painting.

[0032] like Figure 1 , Figure 3 , Figure 7 As shown, the material conveying unit includes a guide pipe 402, which is fixedly installed on the upper surface of the mounting frame 1. A feed valve 401 is fixedly installed on the upper surface of the guide pipe 402. Spray nozzles 403 are fixedly arranged on the sides of the guide pipe 402 and the painting unit respectively. The feed valve 401 is connected to an external material conveying device. During the painting operation, the external material conveying device conveys the painting material to the guide pipe 402 through the feed valve 401, and then sprays the material evenly onto the elastic painting roller 308 through the spray nozzles 403, so that the elastic painting roller 308 can continuously paint, ensuring a continuous supply of painting material and effectively improving the painting efficiency.

[0033] like Figures 1-3 , Figure 5 , Figure 7As shown, the receiving unit includes a receiving hopper 501 and a recovery valve 502. A quick-release assembly for connecting the mounting bracket 1 is fixedly installed on the upper end of the receiving hopper 501. The receiving hopper 501 is located directly below the painting unit. A guide slope connecting the recovery valve 502 is provided inside the receiving hopper 501. The recovery valve 502 is fixedly installed on the lower surface of the receiving hopper 501 and is connected to an external suction device. The receiving hopper 501 is quickly installed onto the mounting bracket 1 using the quick-release assembly. During the painting process, the receiving hopper 501 collects and removes fallen material. Excess paint material is collected and slids through the guide ramp inside the receiving hopper 501 into the recovery valve 502. At the same time, the external suction device generates suction in the receiving hopper 501 through the recovery valve 502, thereby extracting the excess material in the receiving hopper 501 for recycling. In addition, by collecting the dropped material through the receiving hopper 501 and by the external suction device extracting the excess material through the recovery valve 502 and the receiving hopper 501, the pollution caused by splashed material on site is effectively reduced, protecting the site environment.

[0034] like Figure 2 As shown, the quick-release assembly includes a trapezoidal block 503 and a trapezoidal groove 504. The trapezoidal block 503 is fixedly installed on the upper surface of the receiving hopper 501, and the trapezoidal block 503 is slidably installed in the trapezoidal groove 504. The trapezoidal groove 504 is located at the lower side of the mounting frame 1. The mounting frame 1 is fixedly connected to the trapezoidal block 503 by bolts. The trapezoidal block 503 and the trapezoidal groove 504 effectively improve the convenience of disassembling and assembling the receiving hopper 501, thereby facilitating the cleaning of the receiving hopper 501.

[0035] like Figure 1 , Figure 3 , Figure 7 As shown, the adjustment unit includes a bracket 6 and a movable block 7. The bracket 6 is fixedly installed on the connecting seat 2, and a locking mechanism 8 is installed on the bracket 6 by means of a threaded connection. The movable block 7 is fixedly installed on the mounting bracket 1. The movable block 7 is rotatably connected to the bracket 6 and the locking mechanism 8. By adjusting the connection angle between the bracket 6 and the movable block 7, the tilt angle of the painting unit can be adjusted, making it easier for workers to paint. After the bracket 6 and the movable block 7 are adjusted, the locking mechanism 8 is rotated so that the locking mechanism 8 is pressed against the movable block 7, thereby locking the bracket 6 and the movable block 7 and improving the stability of the painting unit.

[0036] Working principle: such as Figure 1 , Figure 3 , Figure 5 , Figure 7As shown, the entire painting device is connected to the external lifting mechanism via the connecting seat 2. The angle of the painting unit is adjusted via the bracket 6 and the movable block 7, and fixed via the locking mechanism 8. The external material conveying device conveys the painting material to the guide pipe 402 via the feed valve 401, and then sprays the material evenly onto the elastic painting roller 308 via the nozzle 403. The external lifting mechanism drives the painting unit to move along the wall via the connecting seat 2, the bracket 6, the movable block 7 and the mounting frame 1, and paints the material onto the wall via the elastic painting roller 308.

[0037] like Figure 1 , Figures 3-7 As shown, during the painting process, the support wheel 306 and the elastic painting roller 308 move along the wall. The damping rod 304 and the spring 305 provide elastic support to the elastic painting roller 308 through the support wheel 306. The support wheel 306 drives the elastic painting roller 308 to rotate through the locking block 309 and the locking groove 310, and the material is painted onto the wall through the elastic painting roller 308.

[0038] like Figure 1 , Figures 3-7 As shown, when encountering a protrusion on the wall during the painting process, the protrusion pushes the support wheel 306 in the opposite direction through the elastic painting roller 308, causing the elastic painting roller 308 to deform. The elastic painting roller 308 compresses the damping rod 304 and spring 305 through the support wheel 306. The damping rod 304 and spring 305 increase the force applied to the elastic painting roller 308 by the support wheel 306, making the elastic painting roller 308 fit tightly against the protrusion of the wall for painting. At the same time, the elastic painting rollers 308 in other positions, not subjected to the reverse force of the protrusion, continue to paint under the support of the damping rod 304 and spring 305. When encountering a depression in the wall, the damping rod 304 and spring 305, supported by the support wheel 306, drive the elastic painting roller 308 into the depression for painting, effectively avoiding missed areas and ensuring the uniformity of the painting.

[0039] like Figures 1-3 , Figure 5 , Figure 7 As shown, during the painting process, excess painting material is collected by the receiving hopper 501. An external suction device generates suction in the receiving hopper 501 through the recovery valve 502, thereby extracting excess material and splashed material from the receiving hopper 501, thus recycling excess painting material and reducing waste.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
