Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a uniform spraying device for building wall construction. Background Technology

[0002] Paint is an important part of decoration. During the wall painting process, uneven paint spraying will lead to uneven wall gloss, easy yellowing, brittleness, cracking and peeling, which will ruin the overall decoration effect. The role of wall paint can play a protective role, a decorative role, and a special function role. Generally speaking, the importance of paint is first reflected in its excellent protective role. Almost all industrial products cannot do without the protection of paint. While achieving the protective role, modern industrial paints also have good decorative effects, making the coated surface produce a variety of decorative effects and greatly beautifying our lives.

[0003] When spraying paint on building walls, it is necessary to mix and stir the paint to prevent pigment sedimentation and unevenness, ensuring a consistent color on the wall during spraying.

A connecting crossbeam 24 is fixedly installed between the two longitudinal sliding seats 23. By controlling the rotation of the two lifting screws 231, the longitudinal sliding seat 23 is driven to slide vertically in the corresponding longitudinal sliding groove 211, thereby driving the connecting crossbeam 24 to perform vertical lifting.

[0039] A rotating tube 25 is rotatably mounted in the middle of the connecting crossbeam 24. A spraying cover 251 is fixedly mounted at the end of the rotating tube 25.

After the first connecting pipe 264 is fixed by setting the first rotating seal 263, it does not affect the rotation of the rotating pipe 25, the spraying cover 251, the spraying connecting pipe 261 and the spraying outer cylinder 26. A guide pipe 8 is fixedly installed between the end of the first connecting pipe 264 and the fifth connector 462. When in use, the second guide pump 46 is turned on. The paint mixed in the storage cylinder 41 is introduced into the spraying connecting pipe 261 and the spraying outer cylinder 26 through the second suction pipe 431, the second pipe 43, the fourth connector 461, the second guide pump 46, the fifth connector 462, the guide pipe 8 and the first connecting pipe 264, and is evenly sprayed out through multiple nozzles 201. It works in conjunction with the drive connecting crossbeam 24 to vertically lift and lower, and paint is sprayed on the building wall from top to bottom.

[0040] A coating roller 27 rotates on the top side of the spraying cover 251 away from the rotating tube 25. A scraper 271 is fixedly installed on the top inner wall of the spraying cover 251 near the rotating tube 25.

During the paint spraying process, the coating roller 27 rolls against the building wall surface, and the coating roller 27 sprays the paint... The painted building wall is coated to improve the smoothness of the paint spraying. Excess paint adheres to the coating roller 27. With the rolling of the coating roller 27, the scraper 271 scrapes the paint on the coating roller 27 into the recycling chamber. At the same time, when the first feed pump 45 is turned on, the paint recovered in the recycling chamber is introduced into the fourth pipe 453 through the L-shaped pipe 272, the recycling pipe 9, the second connector 455, the three-way pipe 451, and the first feed pump 45. It is then introduced into the discharge pipe 47 and the U-shaped cylinder 471 through multiple third connectors 454 and third pipes 44.

A suction pipe 10 is fixedly installed between the input end of the suction pump 6 and the end of the second connecting pipe 284. When in use, the suction pump 6 is turned on. While the paint spraying process is being carried out, the dust and debris on the surface of the building wall can be sucked into the sleeve 28 through the suction groove 281, and then sucked into the storage box 5 through the second connecting pipe 284, the suction pipe 10, and the suction pump 6. This allows for the synchronous and automatic cleaning of dust and debris on the surface of the building wall, preventing dust and debris from adhering to the surface of the building wall and affecting the quality of the paint spraying.

[0042] A worm gear 29 is fixedly fitted at the end of the rotating tube 25 away from the spray cover 251. A first motor 291 is fixedly installed on the outside of the connecting crossbeam 24.

In use, the first motor 291 is turned on to drive the worm 292 to drive the worm gear 29 and the rotating tube 25 to rotate, thereby driving the spray cover 251, the spray cylinder 26, the coating roller 27 and the sleeve 28 to rotate to a vertical position. This facilitates horizontal paint spraying on the building wall through the spray cylinder 26, the coating roller 27 and the sleeve 28, improving the flexibility of the spraying operation.

The drive gear 142 and the crown gear 14 are meshed and connected. By controlling the drive motor 141 to be turned on, the drive gear 142 drives the crown gear 14 and one of the lifting screws 231 to rotate. In conjunction with the first sprocket drive assembly 11, the other lifting screw 231 is driven to rotate synchronously.

[0044] The bottoms of the two stirring shafts 48 extend into the bottom frame 1 of the device. A second sprocket drive assembly 12 is fixedly fitted onto the bottom of the two stirring shafts 48. The second sprocket drive assembly 12 includes two second sprockets and a second chain meshing with the outside of the two second sprockets.

When the lifting screw 231 rotates, it cooperates with the third sprocket drive assembly 13 to drive one of the stirring shafts 48 to rotate. It also cooperates with the second sprocket drive assembly 12 to drive the other stirring shaft 48 to rotate synchronously.

[0045] Working principle: When in use, the paint for spraying is placed in the storage cylinder 41, and the first feed pump 45 is turned on. The paint in the storage cylinder 41 is introduced into the fourth pipe 453 through the first suction pipe 421, the first pipe 42, the first connector 452, the three-way pipe 451, and the first feed pump 45. It is then introduced into the discharge pipe 47 and the U-shaped cylinder 471 through multiple third connectors 454 and third pipes 44. The paint is then sprayed back into the storage cylinder 41 through multiple discharge holes 472 to circulate the paint. Through the back-and-forth circulation of the paint, the paint in the storage cylinder 41 is automatically mixed to prevent the paint in the storage cylinder 41 from settling.

[0046] By controlling the start of the drive motor 141, the drive gear 142 drives the crown gear 14 and one of the lifting screws 231 to rotate. In conjunction with the first sprocket transmission group 11, the other lifting screw 231 is driven to rotate synchronously, driving the longitudinal sliding seat 23 to slide vertically in the corresponding longitudinal sliding groove 211, thereby driving the connecting crossbeam 24 to rise and fall vertically.

[0047] When the lifting screw 231 rotates, it is used in conjunction with the third sprocket drive group 13 to drive one of the stirring shafts 48 to rotate, and in conjunction with the second sprocket drive group 12 to drive the other stirring shaft 48 to rotate synchronously.

[0048] The control starts the second feed pump 46, and the paint that has been mixed in the storage cylinder 41 is introduced into the spraying connecting pipe 261 and the spraying outer cylinder 26 through the second suction pipe 431, the second pipe 43, the fourth connector 461, the second feed pump 46, the fifth connector 462, the feed pipe 8, and the first connecting pipe 264. It is then sprayed evenly through multiple nozzles 201, and is vertically lifted and lowered in conjunction with the drive connecting cross frame 24 to spray paint the building wall from top to bottom.

[0049] During the paint spraying process, the coating roller 27 rolls in contact with the building wall surface, coating the painted surface and improving the smoothness of the paint spraying. Excess paint adheres to the coating roller 27, and with the rolling of the coating roller 27, the scraper 271 scrapes the paint on the coating roller 27 into the recovery chamber. At the same time, when the first feed pump 45 is turned on, the paint recovered in the recovery chamber is introduced into the fourth pipe 453 through the L-shaped pipe 272, the recovery pipe 9, the second connector 455, the three-way pipe 451, and the first feed pump 45. It is then introduced into the discharge pipe 47 and the U-shaped cylinder 471 through multiple third connectors 454 and third pipes 44, and then recirculated into the storage cylinder 41 through multiple discharge perforations 472 for paint recycling.

[0050] During the paint spraying process, the sealing plate 282 rolls in contact with the building wall, and the dust suction channel 281 corresponds to the building wall. The dust suction pump 6 is turned on and can first suck the dust and dirt on the surface of the building wall into the sleeve 28 through the dust suction channel 281, and then into the dust storage box 5 through the second connecting pipe 284, the dust suction pipe 10, and the dust suction pump 6. This allows for the synchronous and automatic cleaning of dust and dirt on the surface of the building wall, preventing dust and dirt from adhering to the surface of the building wall and affecting the quality of the paint spraying.

[0051] By controlling the rotation of the stirring shaft 48, the paint in the storage cylinder 41 is further automatically mixed, which further prevents the paint in the storage cylinder 41 from settling and the pigment from being uneven.

[0052] Specifically, the control starts the first motor 291, which drives the worm gear 292 to drive the worm wheel 29 and the rotating tube 25 to rotate, thereby driving the spraying cover 251, the spraying cylinder 26, the coating roller 27 and the sleeve 28 to rotate to a vertical position, which facilitates horizontal paint spraying on the building wall through the spraying cylinder 26, the coating roller 27 and the sleeve 28, and improves the flexibility of the spraying construction.

[0053] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
