Description

Technical Field

[0001] This application relates to the technical field of decoration spraying equipment, and in particular to a building decoration spraying device with an adjustable spraying range. Background Technology

[0002] In the field of architectural decoration and renovation, spraying has become the mainstream method for surface decoration of walls, furniture, and other items due to its core advantages of uniform coating, high smoothness, and high construction efficiency. Compared with traditional brushing, spraying atomizes dyes such as latex paint under pressure and evenly adsorbs them onto the substrate surface, leaving no brush marks and producing a consistent texture. This significantly improves the quality and efficiency of decoration and is widely used in residential, commercial, and public building decoration scenarios.

[0003] The current mainstream building decoration and finishing spraying equipment mainly consists of a storage tank, a spray gun, a pressure pump, and a delivery pipeline. During spraying, the paint needs to be manually mixed in advance and then added to the storage tank. The pressure pump is then started to drive the pre-mixed paint in the storage tank into the delivery pipeline, which then guides the paint into the spray gun. The spray gun is used to spray the paint onto the building wall for wall decoration spraying treatment.

[0004] Regarding the aforementioned technologies, the inventors discovered that most existing spraying devices lack built-in stirring functions in their storage tanks, requiring manual stirring of the dye before or during application. This affects coating quality, as the uniformity of manual stirring depends entirely on the operator's experience and strength, easily leading to insufficient stirring in certain areas. This results in problems such as color difference, unevenness, and graininess in the sprayed coating. Furthermore, most existing spraying devices use a single nozzle design with a fixed spraying range, making it impossible to flexibly adjust according to the construction scenario, resulting in insufficient adaptability. Summary of the Invention

[0005] To overcome the shortcomings of existing spraying devices, which often lack built-in stirring functions in their storage tanks and require manual stirring of the dye before or during application, thus affecting coating quality, the uniformity of manual stirring depends entirely on the operator's experience and strength, easily leading to insufficient stirring in certain areas and resulting in problems such as color difference, unevenness, and graininess in the sprayed coating. Furthermore, existing spraying devices often use single-nozzle designs with fixed spraying ranges, which cannot be flexibly adjusted according to the construction scenario, resulting in insufficient adaptability. This application provides a building decoration spraying device with an adjustable spraying range.

[0006] The architectural decoration and finishing spraying device with adjustable spraying range provided in this application adopts the following technical solution: An adjustable spraying range building decoration spraying device includes a support component, a material storage component, an adjusting component, a moving component, and a spraying component. The support component includes a support frame with an L-shaped structure, and a sliding frame is vertically fixed to the top of each vertical end face of the support frame. The adjusting component includes an adjusting frame with an L-shaped structure, and a sliding strip is vertically fixed to the output end face of the adjusting frame. The sliding strip is vertically slidably assembled with the sliding frame on the support frame. A material storage component is vertically arranged on the horizontal end face of the support frame, and the output end of the material storage component is connected to the spraying component. The moving component includes a moving plate that moves on the adjusting frame, and the spraying component is arranged on the moving plate.

[0007] By adopting the above technical solution, and through the vertical sliding assembly structure of the sliding frame and sliding bar, the adjusting frame can slide up and down on the support frame, thereby adjusting the overall height of the spraying device as needed. This adjustability of the adjusting frame allows the spraying device to adapt to spraying requirements at different heights, improving the device's versatility and flexibility. Therefore, through this structural design, the lower limit of the spraying range can be flexibly adjusted during operation, thus appropriately improving spraying efficiency. In other words, this structural design significantly enhances the adaptability and flexibility of the spraying device, improving work efficiency. Simultaneously, the support frame has an L-shaped structure with a sliding frame at its top, providing stable support and guidance for the adjusting frame. Therefore, the adjusting frame remains stable during movement, ensuring the stability and uniformity of the spraying process, effectively improving spraying quality and uniformity. Furthermore, the material storage unit and the paint spraying unit are connected and assembled via a moving plate, which can move parallel to the adjusting frame. This design allows the paint in the material storage unit to flow to different paint spraying unit positions according to different spraying requirements, thereby achieving precise control and adjustment of the spraying range. In this way, the spraying device can not only cover a larger spraying area, but also achieve precise spraying of local areas by moving the moving plate, thus improving the flexibility and accuracy of spraying.

[0008] Optionally, multiple rollers are rotatably connected to the bottom horizontal end face of the support frame, and a screw plate is horizontally fixed to the upper side of the vertical end of the support frame.

[0009] By adopting the above technical solution and setting multiple rollers on the horizontal end face of the bottom of the support frame, the contact method between the support frame and the ground is optimized, and the rotatable connection ensures flexible adjustment of direction during movement. Simultaneously, the horizontally fixed screw hole plate on the upper side of the vertical end of the support frame provides for subsequent lifting and painting needs of the equipment.

[0010] Optionally, the storage component includes a storage hopper with an opening at the top and vertically fixed to the bottom horizontal surface of the support frame. The top of the inner circumference of the storage hopper has an internal thread, and a discharge pipe is vertically connected and fixed to the bottom surface of the storage hopper. A one-way valve is connected and fixed to the discharge pipe. A suction pipe is connected and fixed to the bottom of the outer circumference of the storage hopper. A pressure pump is connected and fixed to the suction pipe. A flexible hose with a spiral structure is vertically connected and fixed to the top of the suction pipe. A spiral tube is vertically connected and fixed to the top of the flexible hose. An agitator is installed inside the storage hopper.

[0011] By adopting the above technical solution, the storage hopper, with its open top and vertically fixed to the bottom horizontal surface of the support frame, forms a stable material storage container. The top of the inner circumference of the storage hopper has an internal thread, a design that allows for the installation of a sealing cap or other threaded connections via a screw mechanism, effectively preventing material spillage and maintaining internal sealing. A discharge pipe is vertically connected and fixed to the bottom of the storage hopper, and a one-way valve is fixed to the discharge pipe. This design automatically controls the material flow, ensuring accurate release of material under specific conditions and avoiding material leakage or blockage problems that may occur due to manual operation. A suction pipe is connected and fixed to the bottom of the outer circumference of the storage hopper, where a pressure pump is installed. This arrangement on the suction pipe facilitates the use of external power to drive the pressure pump, promoting material extraction. Simultaneously, a spiral-structured flexible hose is vertically connected and fixed to the top of the suction pipe. The spiral structure helps the hose maintain a stable working state during bending and movement. A helical tube is also vertically connected and fixed to the top of the flexible hose. This design provides additional flexibility for the material extraction path, making it easy to adapt to different working environments and material conveying needs. The mixing components inside the storage tank improve the uniformity of material mixing by rotating and stirring the material, thus preventing the material from separating or clumping during long-term storage.

[0012] Optionally, the mixing component includes a screw cap, which is threadedly assembled with the internal threads at the opening of the storage tank. A mixing screw is vertically rotatably connected to the bottom surface of the screw cap, and a mixing motor is vertically fixed to the top surface of the screw cap. The output end of the mixing motor is fixed to the end of the mixing screw, and multiple mixing blades are fixed vertically on the outer wall of the mixing screw.

[0013] By adopting the above technical solution, the screw cap is assembled with the internal thread at the opening of the storage tank, ensuring the storage tank can be sealed and preventing material leakage during the mixing process. A stirring motor is vertically fixed to the upper end of the screw cap, while the stirring screw is connected to the screw cap via a vertical rotating connection, and the output end of the stirring motor is fixed to the end of the stirring screw. This structural design allows the stirring motor to drive the stirring screw to rotate, thereby efficiently mixing the material in the storage tank. Multiple stirring blades are fixed vertically on the surface of the stirring screw. These blades generate strong shearing and frictional forces when the stirring screw rotates, ensuring uniform mixing of the material in the storage tank. The multiple stirring blades design makes the mixing process more thorough and improves mixing efficiency.

[0014] Optionally, a lifting motor is vertically fixed to the top of the adjusting frame, and a lifting screw is vertically fixed to the output end of the lifting motor. The lifting screw is threaded through and assembled with the screw hole plate at the top of the support frame.

[0015] By adopting the above technical solution, and by setting up a lifting motor and a lifting screw, the lifting motor can precisely control the rotation of the lifting screw, thereby driving the support frame to move vertically. The threaded plate at the top of the support frame is threaded through the lifting screw, meaning that the vertical movement of the support frame can be precisely controlled through threaded transmission. Specifically, when the lifting motor starts and drives the lifting screw to rotate, the support frame achieves smooth vertical lifting under the guidance of the threaded plate, thus fulfilling the lifting requirements of the equipment or platform installed on it.

[0016] Optionally, two belt rollers are horizontally rotatably connected to both the front and rear sides of the outer end face of the adjusting frame, and the two belt rollers are respectively installed on the upper and lower sides of the outer end face of the adjusting frame. An adjusting motor is horizontally fixed on the adjusting frame, and the output end of the adjusting motor is fixed to the end of the belt rollers. Adjusting belts are tensioned and connected to the belt rollers on both sides of the adjusting frame. A support roller is horizontally rotatably connected to the corner end of the adjusting frame, and the support roller is used to support the adjustment belt to rotate and tension.

[0017] By adopting the above technical solution, and by setting belt rollers on both the front and rear sides of the outer end face of the adjusting frame, the belt rollers can be horizontally rotatably connected to the outer end face of the adjusting frame, thus allowing the entire adjusting mechanism to rotate freely within a large range. Since the two belt rollers are respectively installed on the front and rear sides of the outer end face of the adjusting frame, this design allows the system to better adapt to changes in different directions and angles. An adjusting motor is horizontally fixed on the adjusting frame, and the output end of the adjusting motor is fixed to the end of the belt rollers. Through the action of the adjusting motor, the belt rollers can be driven to rotate. The introduction of the adjusting motor enables active adjustment of the belt tension, ensuring that the belt maintains appropriate tension under different loads, avoiding the belt slack phenomenon caused by load changes in traditional mechanisms. In addition, adjusting belts are tensioned and connected to the belt rollers on both sides of the adjusting frame, and support rollers are horizontally rotatably connected at the corner ends of the adjusting frame to support the belt's rotational tension. Through this design, the adjusting belt can be effectively tensioned according to different length requirements, while the application of support rollers ensures stable belt rotation and prevents slippage or slippage during tensioning.

[0018] Optionally, the front and rear sides of the movable plate are horizontally fixed with locking posts, and the two sides of the adjusting frame are fixed with L-shaped guide frames, and the guide frames are inserted through the locking posts on the movable plate. The ends of the locking posts on the front and rear sides of the movable plate are fixed to the outer end face of the adjusting belt.

[0019] By adopting the above technical solution, and through the technical features of the movable plate and the locking posts on the front and rear sides, these locking posts, which can be horizontally inserted into the guide frame on the adjusting frame, ensure that the forward and backward movement of the movable plate can proceed along the guide frame. The locking posts on the front and rear sides of the movable plate are further fixed to the outer end face of the adjusting belt, allowing the forward and backward movement of the movable plate to be driven by the adjusting belt. Therefore, when the adjusting belt is tensioned or relaxed, the movable plate can move precisely up and down or left and right along the guide frame under the guidance of the adjusting frame. This arrangement not only ensures the smoothness and accuracy of the movable plate's movement but also avoids deviation or loosening during movement.

[0020] Optionally, a rotating cylinder is vertically fixed through the bottom surface at the center of the top surface of the movable plate, and an assembly screw tube is fixedly connected to the bottom end of the rotating cylinder. The assembly screw tube is connected to the screw tube at the top end of the flexible hose for assembly. A flip motor is horizontally fixed on the top surface of the movable plate, and a drive gear is fixed at the output end of the flip motor.

[0021] By adopting the above technical solution, the movable plate, capable of vertical movement, serves to support the rotating drum and the tilting motor, allowing the entire device to be adjusted in position as needed. A rotating drum is vertically fixed to the bottom surface of the movable plate, extending from its top center. Because the drum can rotate, it drives the assembly screw tube, which is connected and fixed at its bottom, to rotate as well. The assembly screw tube is connected to the screw tube at the top of the flexible hose, forming a rotatable connection. This rotatable connection allows for flexible adjustment of the hose's direction and position as needed. Simultaneously, a tilting motor is horizontally fixed to the top surface of the movable plate. A drive gear is fixed to the output end of the tilting motor. Through the meshing of the drive gear and the rotating drum, the tilting motor drives the drum to rotate. Since the rotating drum is connected to the assembly screw tube supporting the flexible hose, the tilting motor can drive the hose to rotate and adjust via the drive gear. The overall effect of this device is that it allows for flexible adjustment of the hose's direction and position as needed, improving the device's flexibility and adaptability.

[0022] Optionally, the paint spraying part includes a distributor tube, which is inserted through the rotating drum and rotatably connected to the inner wall of the rotating drum. The outer wall of the distributor tube is located inside the rotating drum and has multiple through holes. A driven gear is fixed through the outer wall of the distributor tube and meshes with the driving gear.

[0023] By adopting the above technical solution and incorporating the characteristics of the diverter tube, which is inserted through and rotatably connected to the inner wall of the rotating drum, it can rotate freely inside the drum. Multiple through holes are also formed on the outer wall of the diverter tube, allowing for even paint spraying onto the workpiece. This results in a more uniform spraying effect when paint is ejected from the high-pressure nozzle of the painting device and passes through the through holes, reducing unevenness and waste. A driven gear is fixed to the outer wall of the diverter tube, and its rotation is synchronized with the drum's rotation through meshing with the driving gear. This design ensures that the diverter tube rotates synchronously with the drum, enabling more even painting of workpieces in different positions and ensuring optimal paint coverage.

[0024] Optionally, multiple extension pipes are horizontally arranged at both ends of the diverter pipe, and screw holes are horizontally opened at both ends of the diverter pipe and the extension pipe. A connecting pipe is provided between the diverter pipe and the extension pipe, and a valve is fixedly connected to the connecting pipe. The two ends of the connecting pipe are connected and assembled with the screw holes at the ends of the adjacent diverter pipe and the extension pipe. Multiple nozzles are fixedly connected to the outer walls of the diverter pipe and the extension pipe.

[0025] By adopting the above technical solution, the horizontally drilled screw holes at both ends of the distribution pipe and extension pipe facilitate assembly and fixation. The distribution pipe and extension pipe are connected by a connecting pipe equipped with a valve, allowing for flexible control of fluid flow. Multiple nozzles are also fixedly connected to the outer walls of the distribution pipe and extension pipe. Adjusting the valve controls the distribution of fluid from the distribution pipe to different extension pipes. The fluid in the distribution pipe is distributed to the multiple extension pipes via the connecting pipe, ensuring uniform fluid distribution. The multiple nozzle design further enhances the fluid dispersion effect, enabling the nozzles to spray the fluid evenly.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Through an integrated design of motor drive and multi-blade agitator, the paint is automatically and thoroughly mixed, completely solving coating quality problems. Continuous and uniform mixing prevents sedimentation and stratification. The motor-driven agitator screw and multiple agitator blades rotate synchronously, forming a three-dimensional mixing flow field that rapidly mixes the paint and solvent. The agitator blades feature a spiral distribution design, covering the entire volume of the storage tank, reducing pigment sedimentation compared to traditional manual mixing and completely avoiding localized incomplete mixing. Simultaneous mixing and spraying ensure uninterrupted construction. The mixing function and pressure pump-assisted spraying can be performed simultaneously, eliminating the need to stop mixing midway and improving the construction speed. Furthermore, it avoids paint splattering caused by manual mixing, increasing material utilization. 2. The device features a triple-adjustable design with width expansion, direction adjustment, and height adjustment, enabling flexible adaptation to various scenarios. The spray width can be infinitely expanded, accommodating both large-area and fine-tuned construction. Multiple extension pipes can be connected in series via connecting pipes to further expand the spray width without the need to replace nozzles. Flexible direction and height adjustment adapts to sidewall and ceiling construction. The motor-driven moving plate moves horizontally, and the rotating motor drives the splitter pipe to rotate, allowing for quick switching between sidewall and ceiling spraying modes without manual equipment handling or angle adjustments, thus improving ceiling construction efficiency. The lifting motor drives the vertical lifting of the adjustment frame, covering the entire height from floor to ceiling, significantly improving construction safety. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses an architectural decoration and finishing spraying device with an adjustable spraying range. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 An adjustable spraying range building decoration spraying device includes a support component 1, a storage component 2, an adjusting component 3, a moving component 4, and a spraying component 5. The support component 1 includes a support frame 11, which has an L-shaped structure, and a sliding frame 12 is vertically fixed to the top of the vertical end face of the support frame 11. The adjusting component 3 includes an adjusting frame 31, which has an L-shaped structure, and a sliding strip 32 is vertically fixed to the output end face of the adjusting frame 31. The sliding strip 32 is vertically slidably assembled with the sliding frame 12 on the support frame 11. The storage component 2 is vertically arranged on the horizontal end face of the support frame 11, and the output end of the storage component 2 is connected and assembled with the spraying component 5. The moving component 4 includes a moving plate 41, which moves on the adjusting frame 31, and the spraying component 5 is arranged on the moving plate 41.

[0031] By adopting the above technical solution, and by setting a vertical sliding assembly structure of sliding frame 12 and sliding bar 32, the adjusting frame 31 can slide up and down on the support frame 11, thereby adjusting the overall height of the spraying device as needed. Due to this adjustability of the adjusting frame 31, the spraying device can adapt to spraying requirements at different heights, improving the versatility and flexibility of the device. Therefore, through this structural design, the lower limit of the spraying range can be flexibly adjusted during operation, thereby achieving the effect of appropriately improving spraying efficiency. That is, this structural design can significantly enhance the adaptability and flexibility of the spraying device and improve work efficiency. Simultaneously, the support frame 11 has an L-shaped structure, and a sliding frame 12 is set on its top, providing stable support and guidance for the adjusting frame 31. Therefore, the adjusting frame 31 can remain stable during movement, ensuring the stability and uniformity of the spraying process, thereby effectively improving the spraying quality and uniformity. Furthermore, the material storage component 2 and the paint spraying component 5 are connected and assembled through a moving plate 41, which can move parallel to the adjusting frame 31. This design allows the paint in the storage unit 2 to flow through different spraying parts 5 according to different spraying requirements, thereby achieving precise control and adjustment of the spraying range. In this way, the spraying device can not only cover a larger spraying area, but also achieve precise spraying of localized areas through the movement of the moving plate 41, improving the flexibility and accuracy of the spraying process.

[0032] Reference Figure 6 Multiple rollers 14 are rotatably connected to the bottom horizontal end face of the support frame 11, and a screw plate 13 is horizontally fixed to the upper side of the vertical end of the support frame 11. By setting multiple rollers 14 on the bottom horizontal end face of the support frame 11, the contact method between the support frame 11 and the ground is optimized, and the rotatable connection ensures flexible adjustment of direction during movement. Simultaneously, the horizontal fixing of the screw plate 13 to the upper side of the vertical end of the support frame 11 provides support for subsequent lifting and painting operations.

[0033] Reference Figure 7 and Figure 8The storage unit 2 includes a storage hopper 21 with an open top and vertically fixed to the bottom horizontal surface of the support frame 11. The top of the inner circumference of the storage hopper 21 has an internal thread 211, and a discharge pipe 212 is vertically connected and fixed to the bottom surface of the storage hopper 21. A one-way valve is connected and fixed to the discharge pipe 212. A suction pipe 22 is connected and fixed to the bottom of the outer circumference of the storage hopper 21, and a pressure pump 221 is connected and fixed to the suction pipe 22. A flexible hose 23 with a spiral structure is vertically connected and fixed to the top of the suction pipe 22. A spiral tube is vertically connected and fixed to the top of the flexible hose 23. A stirring component 24 is installed inside the storage hopper 21. Because the storage hopper 21 has an open top and is vertically fixed to the bottom horizontal surface of the support frame 11, it forms a stable material storage container. The storage hopper 21 has an internal thread 211 on its inner circumferential surface. This design allows for the installation of a sealing cap or other threaded connections via a screw mechanism, effectively preventing material spillage and maintaining internal sealing. A discharge pipe 212 is vertically connected and fixed to the bottom surface of the storage hopper 21, and a one-way valve is fixed to the discharge pipe 212. This design automatically controls the material flow, ensuring accurate release under specific conditions and avoiding material leakage or blockage problems that may occur due to manual operation. A suction pipe 22 is connected and fixed to the bottom of the outer circumferential surface of the storage hopper 21, where a pressure pump 221 is installed. This arrangement on the suction pipe 22 facilitates the external power drive of the pressure pump 221 to promote material extraction. Simultaneously, a spiral-structured hose 23 is vertically connected and fixed to the top of the suction pipe 22. The spiral structure helps the hose 23 maintain a stable working state during bending and movement. A helical tube is also vertically connected and fixed to the top of the hose 23. This design provides additional flexibility for the material extraction path, making it easy to adapt to different working environments and material conveying needs. The stirring component 24 installed inside the storage hopper 21 improves the mixing uniformity of the material by rotating and stirring it, thus preventing stratification or clumping during long-term storage. The stirring component 24 includes a screw cap 241, which is threaded onto the internal thread 211 at the opening of the storage hopper 21. A stirring screw 243 is vertically rotatably connected to the bottom surface of the screw cap 241, and a stirring motor 242 is vertically fixed to the top surface of the screw cap 241. The output end of the stirring motor 242 is fixed to the end of the stirring screw 243. Multiple stirring blades 244 are vertically fixed to the outer wall of the stirring screw 243. The screw cap 241, threaded onto the internal thread 211 at the opening of the storage hopper 21, ensures a sealed storage hopper, preventing material leakage during stirring. A stirring motor 242 is vertically fixed to the upper end of the screw cap 241, while the stirring screw 243 is connected to the screw cap 241 via a vertical rotatable connection, and the output end of the stirring motor 242 is fixed to the end of the stirring screw 243. This structural design enables the stirring motor to drive the stirring screw 243 to rotate, thereby efficiently stirring the material in the storage tank 21.Multiple stirring blades 244 are fixed vertically on the surface of the stirring screw 243. These stirring blades 244 generate strong shearing and frictional forces when the stirring screw 243 rotates, thereby ensuring that the material in the storage tank 21 is mixed evenly. The design of multiple stirring blades 244 makes the mixing process more thorough and improves the mixing efficiency.

[0034] Reference Figure 3 A lifting motor 38 is vertically fixed to the top of the adjusting frame 31, and a lifting screw 39 is vertically fixed to the output end of the lifting motor 38. The lifting screw 39 is threadedly connected to the screw hole plate 13 at the top of the support frame 11. By setting up the lifting motor 38 and the lifting screw 39, the lifting motor 38 can precisely control the rotation of the lifting screw 39, thereby driving the support frame 11 to perform vertical lifting and lowering movements. The screw hole plate 13 at the top of the support frame 11 is threadedly connected to the lifting screw 39, meaning that the vertical movement of the support frame 11 can be precisely controlled through threaded transmission. Specifically, when the lifting motor 38 starts and drives the lifting screw 39 to rotate, the support frame 11 achieves smooth vertical lifting and lowering under the guidance of the screw hole plate 13. This fulfills the lifting and lowering needs of the equipment or platform installed on it. Two belt rollers 33 are horizontally rotatably connected to both the front and rear sides of the outer end face of the adjusting frame 31. The two belt rollers 33 are respectively installed on the upper and lower sides of the outer end face of the adjusting frame 31. An adjusting motor 34 is horizontally fixed on the adjusting frame 31, and the output end of the adjusting motor 34 is fixed to the end of the belt rollers 33. An adjusting belt 35 is tensioned and connected to the belt rollers 33 on both sides of the adjusting frame 31. A support roller 36 is horizontally rotatably connected to the corner end of the adjusting frame 31, and the support roller 36 is used to support the adjusting belt 35 to rotate and tension.

[0035] By incorporating belt rollers 33 on both the front and rear sides of the outer end face of the adjusting frame 31, the belt rollers 33 can be horizontally rotatably connected to the outer end face of the adjusting frame 31, allowing the entire adjusting mechanism to rotate freely within a wide range. Since the two belt rollers 33 are respectively mounted on the front and rear sides of the outer end face of the adjusting frame 31, this design allows the system to better adapt to changes in different directions and angles. An adjusting motor 34 is horizontally fixed on the adjusting frame 31, and the output end of the adjusting motor 34 is fixed to the end of the belt rollers 33. The adjusting motor 34 drives the belt rollers 33 to rotate. The introduction of the adjusting motor 34 enables active adjustment of the belt tension, ensuring that the belt maintains appropriate tension under different loads and avoiding belt slack caused by load changes in traditional mechanisms. Furthermore, adjusting belts 35 are tensioned and connected to the belt rollers 33 on both sides of the adjusting frame 31, and support rollers 36 are horizontally rotatably connected at the corner ends of the adjusting frame 31 to support the directional tension of the adjusting belts 35. With this design, the adjusting belt 35 can be effectively tensioned for different length requirements, while the application of the support roller 36 ensures stable belt rotation and prevents the belt from slipping or slipping during the tensioning process.

[0036] Reference Figure 3 and Figure 4The movable plate 41 has horizontally fixed locking posts 42 on both its front and rear sides. The adjusting frame 31 has L-shaped guide frames 37 fixed on both sides, with the guide frames 37 and the locking posts 42 on the movable plate 41 inserted through each other. The ends of the locking posts 42 on both the front and rear sides of the movable plate 41 are fixed to the outer end faces of the adjusting belt 35. By setting the movable plate 41 and the locking posts 42 on both sides, these locking posts 42 can be horizontally inserted into the guide frames 37 on the adjusting frame 31, thus ensuring that the forward and backward movement of the movable plate 41 can proceed along the guide frames 37. The locking posts 42 on both the front and rear sides of the movable plate 41 are further fixed to the outer end faces of the adjusting belt 35, allowing the forward and backward movement of the movable plate 41 to be driven by the adjusting belt 35. Therefore, when the adjusting belt 35 is tensioned or relaxed, the movable plate 41 can move precisely up and down or left and right along the guide frames 37 under the guidance of the adjusting frame 31. This arrangement not only ensures the smoothness and accuracy of the movement of the movable plate 41, but also avoids deviation or loosening during movement. A rotating cylinder 43 is vertically fixed to the center of the top surface of the movable plate 41, penetrating the bottom surface. An assembly screw tube 44 is fixedly connected to the bottom end of the rotating cylinder 43, and the assembly screw tube 44 is connected to the screw tube at the top of the flexible hose 23. A tilting motor 45 is horizontally fixed to the top surface of the movable plate 41, and a drive gear 451 is fixed to the output end of the tilting motor 45. Because the movable plate 41 can move up and down, it supports the rotating cylinder 43 and the tilting motor 45, allowing the entire device to be adjusted in position as needed. The rotating cylinder 43, which can rotate, drives the assembly screw tube 44, which is fixedly connected to its bottom end, to rotate as well. The assembly screw tube 44 is connected to the screw tube at the top of the flexible hose 23, forming a rotatable connection. This rotatable connection allows for flexible adjustment of the direction and position of the flexible hose 23 as needed. Meanwhile, a tilting motor 45 is horizontally fixed on the top surface of the movable plate 41. A drive gear 451 is fixed to the output end of the tilting motor 45. Through the meshing between the drive gear 451 and the rotating drum 43, the tilting motor 45 can drive the rotating drum 43 to rotate. Since the rotating drum 43 is connected to the assembly screw 44 of the supporting hose 23, the tilting motor 45 can drive the hose 23 to rotate and adjust via the drive gear 451. The overall effect of this device is that it allows for flexible adjustment of the direction and position of the hose 23 as needed, improving the device's flexibility and adaptability.

[0037] Reference Figure 4 and Figure 5The painting component 5 includes a distributor pipe 51, which is inserted through and rotatably connected to the inner wall of the rotating drum 43. Multiple through holes 511 are formed on the outer wall of the distributor pipe 51 inside the rotating drum 43, and a driven gear 52 is fixedly attached to the outer wall of the distributor pipe 51, meshing with a driving gear 451. By designing the distributor pipe 51, it can rotate freely inside the rotating drum 43 because it can be inserted through and rotatably connected to its inner wall. The multiple through holes 511 on the outer wall of the distributor pipe 51 allow the painting component 5 to evenly spray paint onto the workpiece. This results in a more uniform spraying effect when paint is sprayed from the high-pressure nozzle of the painting device and passes through the through holes 511, reducing uneven spraying and waste. A driven gear 52 is fixed to the outer wall of the diverter pipe 51, and the driven gear 52 meshes with the driving gear 451 to achieve synchronous rotation with the rotating drum 43. This design allows the diverter pipe 51 to rotate synchronously with the rotating drum 43, thereby enabling more uniform painting of workpieces located in different positions and ensuring optimal paint coverage. Multiple extension pipes 55 are horizontally arranged at both ends of the diverter pipe 51, and both ends of the diverter pipe 51 and the extension pipes 55 are horizontally provided with screw holes 53. A connecting pipe 54 is provided between the diverter pipe 51 and the extension pipes 55, and a valve 541 is fixedly connected to the connecting pipe 54. The two ends of the connecting pipe 54 are connected and assembled with the screw holes 53 at the ends of the adjacent diverter pipes 51 and the extension pipes 55. Multiple nozzles 56 are fixedly connected to the outer walls of the diverter pipes 51 and the extension pipes 55. The horizontally provided screw holes 53 at both ends of the diverter pipes 51 and the extension pipes 55 facilitate assembly and fixation. The distributor pipe 51 and the extension pipe 55 are connected by a connecting pipe 54, and a valve 541 is installed on the connecting pipe 54 to flexibly control the flow of fluid through the connecting pipe 54. Multiple nozzles 56 are also fixedly connected to the outer walls of the distributor pipe 51 and the extension pipe 55. By adjusting the valve 541, the distribution of fluid from the distributor pipe 51 to different extension pipes 55 can be controlled. The fluid in the distributor pipe 51 is distributed to the multiple extension pipes 55 through the connecting pipe 54, ensuring uniform fluid distribution. The design of multiple nozzles 56 further enhances the fluid dispersion effect, enabling the nozzles 56 to spray the fluid evenly.

[0038] The implementation principle of the building decoration spraying device with adjustable spraying range in this application embodiment is as follows: First, the paint material for spraying is added to the storage tank 21 of the storage component 2, and then mixed water is added. The screw cap 241 of the agitator 24 is set at the top opening of the storage tank 21. The screw cap 241 is rotated to engage with the inner thread 211 on the upper side of the inner wall of the storage tank 21, thus completing the fixed assembly of the agitator 24 and the storage tank 21. Then, the agitator motor 242 is started to drive the agitator screw 243 to rotate. The rotating agitator screw 243 agitates the raw material and solvent to mix. Then, multiple agitator blades 244 are fixed on the outer wall of the agitator screw 243 to agitate the raw material and solvent to mix thoroughly. When the paint is sprayed onto the wall, the pressure pump 221 on the outer suction pipe 22 of the storage tank 21 is started to drive the mixed paint into the spraying component 5 for spraying. At the same time, the excess paint remaining in the storage tank 21 is discharged by opening the one-way valve on the discharge pipe 212 on the bottom surface of the storage tank 21. Then, during painting, the support frame 11 is moved to a suitable position using the rollers 14. During painting, the lifting motor 38 on the top surface of the adjusting frame 31 in the adjusting component 3 is activated. The lifting motor 38 drives the lifting screw 39 to rotate. The screw 39 is threaded through the screw hole plate 13 on the top surface of the support frame 11, pushing the adjusting frame 31 to slide vertically on the support frame 11. The painting height is adjusted vertically to meet the painting requirements of different heights. At the same time, in order to expand the painting range according to the painting width, multiple extension pipes 55 are horizontally connected and assembled at both ends of the diversion pipe 51. The painting width of the diversion pipe 51 is expanded by the multiple extension pipes 55. When the diversion pipe 51 is connected to the multiple extension pipes 55, the diversion pipe 51 is connected to the extension pipes 55 and adjacent extension pipes 55 through the connecting pipe 54. Then, the valve 541 on the connecting pipe 54 is opened, and the paint flows in the diversion pipe 51 and the multiple extension pipes 55, expanding the paint spraying range. Secondly, according to the painting requirements, when adjusting the painting of the side walls and the top walls, the adjustment motor 34 on the top surface of the adjustment frame 31 is started to drive the belt roller 33 to rotate, and the tension drives the adjustment belt 35 to run. The running adjustment belt 35 drives the locking pins 42 on both sides of the moving plate 41 to move laterally in the guide frame 37, thereby driving the painting parts 5 on the moving plate 41 to spray the side walls or the top walls. At the same time, in order to adjust the painting direction of the nozzle 56, the flip motor 45 on the moving plate 41 is started to drive the drive gear 451 to rotate, which meshes with the driven gear 52 on the outer wall of the diversion pipe 51, driving the diversion pipe 51 to rotate in the rotating drum 43, thereby adjusting the painting direction of 56, which is suitable for the painting requirements of the side walls and the top walls.
