Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to a spraying treatment device for building surfaces. Background Art

[0002] Building projects are exposed to wind, sun, rain, wear, corrosion, etc. for a long time, and their surfaces are often the first to start to deteriorate. In order to extend the service life of building construction, it is necessary to perform spraying treatment on the surfaces of buildings. Generally, a spraying machine is used for direct spraying to change the composition and microstructure of the building surface, thereby improving and enhancing its performance and increasing the service life of building materials. However, when performing spraying treatment on the building surface, there are defects in spraying and many problems occur. Usually, a spraying treatment device is needed during spraying to assist in the smooth completion of the spraying work and improve the quality of building surface spraying.

[0003] Most of the current building surface spraying treatment devices have the same structure. They all achieve spraying through a liquid spraying pump. The overall structure is complex, the volume is large, and it is not convenient to carry. When the spraying treatment device is in use, the paint is generally sprayed onto the building surface, and the situation of wrinkled surfaces occurs, which easily causes the paint to be uneven. If there are bumps or attachments on the surface of the building, it will affect spraying and cause the paint to easily fall off. It is necessary to grind and remove the bumps or attachments before spraying. If there is dust on the surface of the building, it will affect spraying. When the paint device grinds and removes the bumps or attachments on the building materials, dust will be generated, and some dust will adhere to the surface of the building. If the grinding dust or dust on the surface of the building is difficult to clean, it will affect spraying. Summary of the Invention

It is necessary to grind and remove the bumps or attachments before spraying; if there is dust on the surface of the building, it will affect spraying. When the paint device grinds and removes the bumps or attachments on the building materials, dust will be generated, and some dust will adhere to the surface of the building. If the grinding dust or dust on the surface of the building is difficult to clean, it will affect spraying, etc.

The cross-section of the rotating shaft is elliptical, and a rough surface and a smooth surface are arranged on the surface of the rotating shaft;

[0012] A corrugated pipe is arranged between the toothed disc and the rotating ring. On the rotating ring, air spraying holes are arranged, and the air spraying holes are communicated with the corrugated pipe. At the bottom of the corrugated pipe, an air inlet valve is arranged, and the air inlet valve is fixed on the lower surface of the toothed disc.

[0013] Preferably, a guide rod is fixedly connected to the upper surface of the supporting handle. A hole is arranged inside the right-angle rack, and the guide rod penetrates through the hole inside the right-angle rack.

[0015] Preferably, the driving components are arranged in an annular array around the axis of the rotating cylinder. The toothed disc drives the rotating cylinder to rotate, and the rotating cylinder drives the rotating ring to rotate.

[0016] Preferably, a thrust bearing is arranged between the spraying substrate and the toothed disc. At the edge of the upper surface of the spraying substrate, a right-angle fixing plate is arranged. A servo motor is installed on the top of the right-angle fixing plate. The output end of the servo motor is fixedly connected with a main gear, and the main gear meshes with the toothed disc.

[0020] Preferably, protective covers are fixedly connected to the edges of the upper surface of the spraying substrate. A thrust bearing is arranged between the spraying substrate and the rotating cylinder, and the thrust bearing is sleeved on the fixed column.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. When the servo motor is started in the present invention, the servo motor drives the main gear to rotate, so that the main gear drives the toothed disc to rotate self - rotatably, the toothed disc drives the rotating cylinder to rotate self - rotatably, the rotating ring rotates self - rotatably through the guide bar, and the rotating ring drives the rotating shaft to rotate, so that the rotating shaft rotates around the axis of the rotating cylinder. When the rotating shaft rotates, the paint on the building surface can be smoothed by the self - rotation of the rotating shaft. At this time, the smooth surface of the rotating shaft contacts the paint, increasing the flatness of the paint on the building surface.

[0023] 2. When the servo motor is started in the present invention, the rotating shaft rotates around the axis of the rotating cylinder. At this time, the free end of the second telescopic rod extends, and the right - angled rack rises and falls, so that the right - angled rack drives the conversion gear to rotate, the conversion gear drives the rotating rod to rotate, and the rotating rod drives the rotating shaft to flip, turning the rough surface of the rotating shaft from bottom to top. At this time, the rough grinding surface of the rotating shaft contacts the convex blocks or attachments. When the rotating shaft rotates, the rough surface of the rotating shaft grinds and removes the convex blocks or attachments.

[0024] 3. When the second telescopic rod is started in the present invention, the free end of the second telescopic rod drives the right - angled rack to rise and fall, and the inclination angle of the rotating shaft is adjusted through the conversion gear. Since the cross - section of the rotating shaft is elliptical, the rotating shaft is in the fan - blade angle. When the rotating shaft rotates, a blowing force is generated by the rotating shaft to blow away the dust on the building surface.

[0025] 4. In the present invention, the free end of the first telescopic rod is extended or retracted, then the rotating ring slides up and down on the rotating cylinder, the rotating ring presses on the corrugated pipe, compressing the air pressure inside the corrugated pipe, and the air inlet valve prevents the gas inside the corrugated pipe from discharging. Then, the gas inside the corrugated pipe is ejected from the air spraying holes. When the corrugated pipe is stretched, external gas enters the inside of the corrugated pipe through the air inlet valve, further blowing away the grinding dust or dust, avoiding affecting the spraying.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0038] The present invention provides the following technical solutions (please refer to Figures 1-9 ):

[0039] Reference Figure 1 and Figure 7 , the present invention provides a spraying treatment device for a building surface, including a spraying substrate 1. A fixing column 2 is fixedly connected to the center inside the spraying substrate 1. A rotating cylinder 23 is sleeved on the fixing column 2. A gear disk 3 is fixedly connected to the edge of the bottom of the rotating cylinder 23. A rotating ring 4 is sleeved on the top of the rotating cylinder 23. A driving component 5 is arranged at the edge of the upper surface of the gear disk 3.

[0040] Reference Figure 8 and Figure 9 , the driving component 5 includes a first telescopic rod 501. The free end of the first telescopic rod 501 is fixed to the rotating ring 4. The free end of the first telescopic rod 501 drives the rotating ring 4 to move up and down. A supporting handle 502 is fixedly connected to one side surface of the first telescopic rod 501. A second telescopic rod 503 is fixedly connected to the upper surface of the supporting handle 502. A right-angle rack 504 is fixedly connected to the free end of the second telescopic rod 503.

[0041] Reference Figure 4 and Figure 7 , a rotating shaft assembly 6 is arranged inside the rotating ring 4 through a radial bearing; the rotating shaft assembly 6 includes a rotating rod 601. The rotating rod 601 is movably connected to the rotating ring 4 through a bearing. A changing gear 602 is fixedly connected to the surface of the rotating rod 601. A rotating shaft 603 is fixedly connected to the end of the rotating rod 601. The changing gear 602 meshes with the right-angle rack 504. The cross-section of the rotating shaft 603 is elliptical, and a rough surface and a smooth surface are arranged on the surface of the rotating shaft 603.

[0042] More specifically, when the servo motor 13 is started, the servo motor 13 drives the main gear 14 to rotate, so that the main gear 14 drives the gear disk 3 to rotate self, the gear disk 3 drives the rotating cylinder 23 to rotate self, the rotating ring 4 is driven to rotate self through the guide bar 10, the rotating ring 4 drives the rotating shaft 603 to rotate, so that the rotating shaft 603 rotates around the axis of the rotating cylinder 23. When the rotating shaft 603 rotates, the paint on the building surface can be smoothed by the self-rotation of the rotating shaft 603. At this time, the smooth surface of the rotating shaft 603 contacts the paint, increasing the flatness of the paint on the building surface.

[0043] More specifically, when the servo motor 13 is started, the rotating shaft 603 rotates around the axis of the rotating cylinder 23. At this time, the free end of the second telescopic rod 503 extends, causing the right-angle rack 504 to move up and down, so that the right-angle rack 504 drives the conversion gear 602 to rotate. The conversion gear 602 drives the rotating rod 601 to rotate, and then the rotating rod 601 drives the rotating shaft 603 to flip, turning the rough surface of the rotating shaft 603 from bottom to top. At this time, the rough grinding surface of the rotating shaft 603 contacts the bumps or attachments. When the rotating shaft 603 rotates, the rough surface of the rotating shaft 603 grinds and removes the bumps or attachments.

[0044] More specifically, start the second telescopic rod 503, so that the free end of the second telescopic rod 503 drives the right-angle rack 504 to move up and down. The inclination angle of the rotating shaft 603 is adjusted through the conversion gear 602. Since the cross-section of the rotating shaft 603 is oval, the rotating shaft 603 is in the fan blade angle. When the rotating shaft 603 rotates, it generates a blowing force to blow away the dust on the building surface.

[0045] Reference Figure 6 And Figure 7 Between the toothed disc 3 and the rotating ring 4, there is a corrugated pipe 7. There are air injection holes 8 on the rotating ring 4, and the air injection holes 8 are connected to the corrugated pipe 7. An air inlet valve 9 is provided at the bottom of the corrugated pipe 7, and the air inlet valve 9 is fixed to the lower surface of the toothed disc 3.

[0046] More specifically, only need to start the free end of the first telescopic rod 501 to expand and contract. Then the rotating ring 4 slides up and down on the rotating cylinder 23. The rotating ring 4 presses on the corrugated pipe 7, compressing the air pressure inside the corrugated pipe 7. And the air inlet valve 9 prevents the gas inside the corrugated pipe 7 from discharging. Then the gas inside the corrugated pipe 7 is ejected from the air injection holes 8. When the corrugated pipe 7 is stretched, the external gas enters the inside of the corrugated pipe 7 through the air inlet valve 9, further blowing away the grinding dust or dust to avoid affecting the spraying.

[0047] Reference Figure 8 And Figure 9 On the upper surface of the handle 502, there is a guide rod 505 fixedly connected. There are holes inside the right-angle rack 504, and the guide rod 505 penetrates through the holes inside the right-angle rack 504.

[0048] More specifically, when the right-angle rack 504 moves up and down, the stability of the right-angle rack 504 can be increased through the guide rod 505.

[0049] Reference Figure 7 On the surface of the rotating cylinder 23, there is a guide strip 10 fixedly connected. At the bottom of the rotating ring 4, there is a sliding shell 11 fixedly connected. The guide strip 10 is slidably connected to the rotating ring 4 and the sliding shell 11.

[0050] More specifically, when the rotating ring 4 is lifted or lowered on the rotating cylinder 23 , the rotating ring 4 drives the sliding shell 11 to slide on the guide bar 10 , thereby increasing the stability of the rotating ring 4 through the cooperation between the guide bar 10 and the sliding shell 11 .

[0051] refer to Figure 5 , Figure 6 and Figure 7 A thrust bearing is arranged between the spraying substrate 1 and the toothed disc 3, a right-angle fixing plate 12 is arranged at the edge of the upper surface of the spraying substrate 1, a servo motor 13 is installed on the top of the right-angle fixing plate 12, and a main gear 14 is fixedly connected to the output end of the servo motor 13, and the main gear 14 is meshed with the toothed disc 3.

[0052] More specifically, when the servo motor 13 is started, the servo motor 13 drives the main gear 14 to rotate, so that the main gear 14 drives the gear plate 3 to rotate.

[0053] refer to Figure 2 , Figure 5 and Figure 6 A spray hole 15 is provided inside the rotating cylinder 23, a nozzle 16 is threadedly connected to the fixed column 2, and the nozzle 16 is adapted to the spray hole 15, a paint pump 18 is installed on the lower surface of the spraying substrate 1 through a sealing gasket 17, the output port of the paint pump 18 is adapted to the spray hole 15, and a hose 19 is provided at the input port of the paint pump 18.

[0054] More specifically, through the coordinated arrangement of the spray hole 15, the nozzle 16, the paint pump 18 and the hose 19, the end of the hose 19 can be inserted into the paint, and the paint can enter the spray hole 15 by opening the paint pump 18, and then enter the nozzle 16 from the spray hole 15, and then the paint can be sprayed out by the nozzle 16. Through the arrangement of the sealing gasket 17, since the output port of the paint pump 18 is connected to the spray hole 15, the sealing gasket 17 can prevent the paint from overflowing.

[0055] refer to Figure 2 A first handle 20 is fixedly connected to the lower surface of the spray-coated substrate 1 , and a second handle 21 is fixedly connected to the edge of the spray-coated substrate 1 .

[0056] More specifically, by cooperating with the first handle 20 and the second handle 21 , the user can operate the device conveniently and the device is easy to carry.

[0057] refer to Figure 1 and 6 A protective cover 22 is fixedly connected to the edge of the upper surface of the spraying substrate 1 , a thrust bearing is arranged between the spraying substrate 1 and the rotating cylinder 23 , and the thrust bearing is sleeved on the fixed column 2 .

[0058] More specifically, by providing the protective cover 22, the protection and safety of the device can be increased.

[0059] The working principle and usage process of the present invention are as follows:

[0060] When the spraying treatment device is in use, spraying the paint onto the building surface through the nozzle 16 easily causes the paint to be uneven and wrinkled; when the servo motor 13 is started, the servo motor 13 drives the main gear 14 to rotate, causing the main gear 14 to drive the toothed disc 3 to rotate self - rotatably, the toothed disc 3 drives the rotating cylinder 23 to rotate self - rotatably, the rotating ring 4 rotates self - rotatably through the guide bar 10, the rotating ring 4 drives the rotating shaft 603 to rotate, so that the rotating shaft 603 rotates around the axis of the rotating cylinder 23. When the rotating shaft 603 rotates, the paint on the building surface can be smoothed by the self - rotation of the rotating shaft 603 (at this time, the smooth surface of the rotating shaft 603 is in contact with the paint, as Figure 7 shown), increasing the smoothness of the paint on the building surface.

[0061] When the spraying treatment device is in use, if there are bumps or attachments on the surface of the building, it will affect spraying and cause the paint to easily fall off. It is necessary to polish and remove the bumps or attachments before spraying; when the servo motor 13 is started, the rotating shaft 603 rotates around the axis of the rotating cylinder 23. At this time, the free end of the second telescopic rod 503 extends and the right - angled rack 504 moves up and down, causing the right - angled rack 504 to drive the conversion gear 602 to rotate, the conversion gear 602 drives the rotating rod 601 to rotate, and the rotating rod 601 drives the rotating shaft 603 to flip, turning the rough surface of the rotating shaft 603 from bottom to top (at this time, the rough grinding surface of the rotating shaft 603 is in contact with the bumps or attachments, as Figure 7 shown). When the rotating shaft 603 rotates, the rough surface of the rotating shaft 603 polishes and removes the bumps or attachments.

[0062] When the spraying treatment device is in use, if there is dust on the surface of the building, it will affect spraying. When the paint device polishes and removes the bumps or attachments on the building material, dust will be generated, and some dust will adhere to the surface of the building, affecting spraying; start the second telescopic rod 503, so that the free end of the second telescopic rod 503 drives the right - angled rack 504 to move up and down, adjust the inclination angle of the rotating shaft 603 through the conversion gear 602. Since the cross - section of the rotating shaft 603 is elliptical, the rotating shaft 603 is in the fan - blade angle. When the rotating shaft 603 rotates, it generates a blowing force to blow away the dust on the building surface.

[0063] In addition, if it is difficult to clean the surface grinding dust or dust of the building, at this time, the spraying treatment device is slightly moved away from the building materials; only the free end of the first telescopic rod 501 needs to be extended or retracted, then the rotating ring 4 slides up and down on the rotating cylinder 23, the rotating ring 4 presses on the corrugated pipe 7, compresses the air pressure inside the corrugated pipe 7, and the air inlet valve 9 prevents the gas inside the corrugated pipe 7 from discharging, so that the gas inside the corrugated pipe 7 is ejected from the air spraying holes 8. When the corrugated pipe 7 is stretched, the external gas enters the inside of the corrugated pipe 7 through the air inlet valve 9, and further blows away the grinding dust or dust, avoiding affecting the spraying.

[0064] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
