Description

Technical Field

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

[0002] In the current building decoration industry, spraying technology is widely used due to its high efficiency and uniformity. Traditional spraying equipment mainly includes manual spray guns and high-pressure airless sprayers. With the rapid development of the construction industry, the requirements for spraying efficiency and quality are constantly increasing. In order to improve spraying uniformity and efficiency, mobile spraying devices are now mostly used to avoid the uneven spraying caused by the instability of manually held spray guns.

[0003] Existing spraying equipment cannot accurately control the distance between itself and the spraying surface when it moves, and the distance between itself and the spraying surface will change during the movement, affecting the uniformity of the spraying. Utility Model Content

[0004] The purpose of this application is to provide a building decoration and finishing spraying device, which has the advantages of accurately controlling the distance between the device and the spraying surface, keeping the device and the spraying surface at a specified distance at all times, and thus being able to perform spraying operations on the spraying surface uniformly at all times. This solves the problem that existing spraying devices cannot accurately control the distance between themselves and the spraying surface when moving, and the distance between themselves and the spraying surface changes during the movement, affecting the uniformity of spraying.

[0005] The technical solution of the building decoration and finishing spraying device provided in this application is as follows: A building decoration and finishing spraying device includes a support frame, a universal wheel is fixedly installed at the bottom of the support frame, a storage tank is fixedly installed at the top of the support frame, the outlet of the storage tank is connected to a pressure pump through a material conveying pipe, the pressure pump is connected to a spray head through a connecting hose, a connecting plate is provided at one end of one side of the support frame, two connecting rods are connected at both ends of the connecting plate through two hinge components, the hinge component includes a U-shaped frame, the U-shaped frame is fixedly installed at one end of one side of the connecting plate, a rotating shaft is rotatably installed inside the U-shaped frame, the two ends of the rotating shaft pass through the two ends of the U-shaped frame, a hinge block is rotatably installed on the outer surface of the middle part of the rotating shaft, one end of the hinge block is fixedly installed at one end of the connecting rod, a positioning wheel is rotatably installed at the end of the connecting rod away from the connecting plate through the connecting frame, a threaded sleeve is fixedly installed at the bottom of the connecting plate through a fixing block, a first threaded rod is threadedly connected to the inner wall of the middle part of the threaded sleeve, and the outer surface of the middle part of the first threaded rod is rotatably installed at the bottom of the support frame through the connecting frame.

[0006] By adopting the above technical solution, the positioning wheel can always be in contact with the spraying surface to position the distance between the device and the spraying surface, effectively preventing changes in the distance between the device and the spraying surface during the movement of the device, and providing a stable distance basis for uniform spraying of the nozzle. At the same time, rotating the first threaded rod can drive the threaded sleeve to move axially, thereby pushing the connecting plate and connecting rod to adjust their positions synchronously, adjusting the distance between the positioning wheel and the support frame. The distance between the spraying surface and the device can be adjusted according to the spraying requirements. The connecting rod can swing on one side of the connecting plate through the hinge assembly. After the spraying work is completed, the angle of the connecting rod can be adjusted to facilitate the storage of the device.

[0007] Preferably, two limiting rods are fixedly provided at both ends of the connecting plate near the support frame, and the outer surface of the middle part of the two limiting rods is slidably disposed within the inner wall of the end of the support frame.

[0008] By adopting the above technical solution, the limiting rod can slide within the inner wall of the end of the support frame, thereby restricting the movement direction of the connecting plate, preventing the connecting plate from shifting when adjusted with the threaded sleeve and the first threaded rod, fixing the trajectory of the connecting plate's movement, and improving the stability of the connecting plate during movement.

[0009] Preferably, a support plate is fixedly provided at the top of the rotating shaft, a positioning rod is slidably provided on the inner wall of one end of the support plate, a limit plate is fixedly provided at the top of the U-shaped frame, and one end of the positioning rod is inserted into the inner wall of one end of the limit plate.

[0010] By adopting the above technical solution, one end of the positioning rod is inserted into the inner wall of one end of the limiting plate, which can fix the angle between the connecting rod and the connecting plate, and prevent the connecting rod from swinging during operation, which would affect the distance between the device and the spraying surface.

[0011] Preferably, a fixing plate is fixedly provided at one end of the positioning rod, and a spring is provided between the fixing plate and the support plate. One end of the spring is fixedly provided on one side of the fixing plate, and the other end of the spring is fixedly provided on one side of the support plate.

[0012] By adopting the above technical solution, the spring can apply a thrust to the positioning rod through the fixed plate, so that the positioning rod can be stably inserted into the inner wall of one end of the limiting plate, thus preventing the one end of the positioning rod from sliding out of the inner wall of one end of the limiting plate during the operation, which would prevent the angle between the connecting rod and the connecting plate bracket from being fixed.

[0013] Preferably, a worm gear is fixedly provided at one end of the first threaded rod, the worm gear meshes with the worm, and the worm is rotatably mounted at one end of the support frame via a connecting frame.

[0014] By adopting the above technical solution, the rotation of the worm can drive the rotation of the worm wheel, which in turn drives the first threaded rod to rotate. This allows for adjustment of the position of the connecting plate. At the same time, the self-locking property between the worm wheel and the worm can prevent the first threaded rod from rotating on its own after it has been adjusted to the correct position due to device vibration or external force. This ensures the effective fixation of the first threaded rod on the threaded sleeve and the connecting plate, and prevents the distance between the device and the spraying surface from changing due to accidental rotation of the first threaded rod.

[0015] Preferably, two positioning clips are fixedly installed at both ends of one side of the connecting plate, corresponding to the positions of the two connecting rods, and the connecting rods are engaged inside the positioning clips.

[0016] By adopting the above technical solution, the connecting rod can be snapped into the positioning card when it needs to be stored, thus fixing the position of the connecting rod and preventing it from swinging randomly and colliding, which could cause damage.

[0017] Preferably, a positioning frame is fixedly installed on the top of the support frame, and a second threaded rod is rotatably installed on the inner wall of the positioning frame. One end of the second threaded rod extends to the top of the positioning frame. A motor is fixedly installed on the top of the positioning frame through a fixing frame. One end of the second threaded rod is fixedly installed on one end of the motor output shaft. A connecting block is threadedly connected to the outer surface of the middle part of the second threaded rod. The connecting block is fixedly installed on one end of the nozzle.

[0018] By adopting the above technical solution, the operation of the motor can drive the second threaded rod to rotate, and the rotation of the second threaded rod can drive the connecting block to move, thereby adjusting the height of the connecting block and thus adjusting the spraying height of the spray head according to the spraying requirements.

[0019] Preferably, the specifications of the connecting block are adapted to the specifications of the inner wall of the middle part of the positioning frame, and the outer surfaces of both ends of the connecting block are slidably connected to the outer surfaces of both sides of the inner wall of the middle part of the positioning frame.

[0020] By adopting the above technical solution, the angle of the connecting block when it moves can be limited, preventing the connecting block from rotating as the second threaded rod rotates. This ensures that the rotation of the second threaded rod can stably drive the connecting block to move in a straight line, thereby allowing for stable adjustment of the nozzle height.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This building decoration and finishing spraying device uses two positioning wheels that work together to fit the spraying surface. As the device moves, the positioning wheels roll on the spraying surface, and the distance between the device and the spraying surface is fixed by a connecting rod and a hinge assembly. This allows for precise control of the distance between the device and the spraying surface, ensuring that the device and the spraying surface are always kept at a specified distance, thus enabling uniform spraying operations on the spraying surface.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A building decoration and finishing spraying device, please refer to... Figure 1 , Figure 2 and Figure 3 The system includes a support frame 1, with casters 2 fixedly mounted at the bottom. A storage tank 3 is fixedly mounted at the top of the support frame 1. A pressure pump 4 is connected to the outlet of the storage tank 3 via a conveying pipe. A nozzle 6 is connected to the pressure pump 4 via a connecting hose 5. A connecting plate 7 is provided at one end of one side of the support frame 1. Two connecting rods 9 are connected to the two ends of the connecting plate 7 via two hinge components 8. The hinge component 8 includes a U-shaped frame 801, which is fixedly mounted at one end of the connecting plate 7. A rotating shaft 80 is rotatably mounted inside the U-shaped frame 801. 2. The two ends of the rotating shaft 802 pass through the two ends of the U-shaped frame 801. The outer surface of the middle part of the rotating shaft 802 is rotatably provided with a hinge block 803. One end of the hinge block 803 is fixedly provided with one end of the connecting rod 9. The end of the connecting rod 9 away from the connecting plate 7 is rotatably provided with a positioning wheel 10 through the connecting frame. The bottom of the connecting plate 7 is fixedly provided with a threaded sleeve 12 through a fixing block. The inner wall of the middle part of the threaded sleeve 12 is threadedly connected with a first threaded rod 13. The outer surface of the middle part of the first threaded rod 13 is rotatably provided with the bottom of the support frame 1 through the connecting frame.

[0026] Please see Figure 2 and Figure 3 Two limiting rods 11 are fixedly installed at both ends of the connecting plate 7 near the support frame 1. The middle outer surface of the two limiting rods 11 is slidably disposed in the inner wall of the end of the support frame 1. The limiting rods 11 can slide in the inner wall of the end of the support frame 1 to restrict the movement direction of the connecting plate 7, prevent the connecting plate 7 from deviating when it is adjusted with the threaded sleeve 12 and the first threaded rod 13, fix the movement trajectory of the connecting plate 7, and improve the stability of the connecting plate 7 when it moves.

[0027] Please see Figure 1 , Figure 2 and Figure 5 A support plate 25 is fixedly installed at the top of the rotating shaft 802. A positioning rod 21 is slidably installed on the inner wall of one end of the support plate 25. A limit plate 22 is fixedly installed at the top of the U-shaped frame 801. One end of the positioning rod 21 is inserted into the inner wall of one end of the limit plate 22. The angle between the connecting rod 9 and the connecting plate 7 can be fixed to prevent the connecting rod 9 from swinging during operation, which would affect the distance between the device and the spraying surface.

[0028] Please see Figure 1 , Figure 2 and Figure 5 A fixing plate 24 is fixedly installed at one end of the positioning rod 21. A spring 23 is installed between the fixing plate 24 and the support plate 25. One end of the spring 23 is fixedly installed on one side of the fixing plate 24, and the other end of the spring 23 is fixedly installed on one side of the support plate 25. The spring 23 can apply a pushing force to the positioning rod 21 through the fixing plate 24, so that the positioning rod 21 can be stably inserted into the inner wall of one end of the limiting plate 22. This prevents the one end of the positioning rod 21 from sliding out of the inner wall of one end of the limiting plate 22 during the operation, which would prevent the angle between the connecting rod 9 and the bracket of the connecting plate 7 from being fixed.

[0029] Please see Figure 1 , Figure 2 and Figure 3 A worm gear 14 is fixedly installed at one end of the first threaded rod 13. The worm gear 14 meshes with the worm 15. The worm 15 is rotatably mounted at one end of the support frame 1 through the connecting frame. The rotation of the worm 15 can drive the worm gear 14 to rotate, which in turn drives the first threaded rod 13 to rotate. This allows for adjustment of the position of the connecting plate 7. At the same time, the self-locking property between the worm gear 14 and the worm 15 prevents the first threaded rod 13 from rotating on its own after it has been adjusted to the correct position due to device vibration or external force. This ensures the effective fixation of the first threaded rod 13 on the threaded sleeve 12 and the connecting plate 7, and prevents the distance between the device and the spraying surface from changing due to accidental rotation of the first threaded rod 13.

[0030] Please see Figure 3 and Figure 5 Two positioning clips 16 are fixedly installed at both ends of one side of the connecting plate 7, corresponding to the positions of the two connecting rods 9. The connecting rods 9 are snapped into the inside of the positioning clips 16. When the connecting rods 9 need to be stored, they can be snapped into the positioning clips 16 to fix the position of the connecting rods 9 and prevent the connecting rods 9 from swinging randomly and causing collisions and damage.

[0031] Example 2: A building decoration and finishing spraying device, please refer to... Figure 1 , Figure 2 and Figure 4 A positioning frame 17 is fixedly installed on the top of the support frame 1. A second threaded rod 19 is rotatably installed on the inner wall of the positioning frame 17. One end of the second threaded rod 19 extends above the positioning frame 17. A motor 20 is fixedly installed on the top of the positioning frame 17 through a fixing frame. One end of the second threaded rod 19 is fixedly installed on one end of the output shaft of the motor 20. A connecting block 18 is threadedly connected to the outer surface of the middle part of the second threaded rod 19. The connecting block 18 is fixedly installed on one end of the spray head 6. When the motor 20 works, it can drive the second threaded rod 19 to rotate. The rotation of the second threaded rod 19 can drive the connecting block 18 to move, thereby adjusting the height of the connecting block 18. In this way, the spraying height of the spray head 6 can be adjusted according to the spraying requirements.

[0032] Please see Figure 1 and Figure 4 The specifications of the connecting block 18 are adapted to the specifications of the inner wall of the middle part of the positioning frame 17. The outer surfaces of both ends of the connecting block 18 are slidably connected to the outer surfaces of both sides of the inner wall of the middle part of the positioning frame 17. This can limit the angle when the connecting block 18 moves, prevent the connecting block 18 from rotating with the rotation of the second threaded rod 19, and ensure that the rotation of the second threaded rod 19 can stably drive the connecting block 18 to move in a straight line, thereby stably adjusting the height of the nozzle 6.

[0033] The implementation principle of this embodiment is as follows: According to the spraying requirements, the worm gear 15 is rotated, causing the worm gear 15 to drive the worm wheel 14 to rotate, which in turn drives the first threaded rod 13 to rotate. When the first threaded rod 13 rotates, it drives the connecting plate 7 to move through the threaded sleeve 12. Adjusting the distance between the connecting plate 7 and the support frame 1 causes the connecting plate 7 to drive the positioning wheel 10 to move. Adjusting the distance between the positioning wheel 10 and the support frame 1 moves the device, causing the two positioning wheels 10 to fit against the spraying surface. The pressure pump 4 is then started, and material is supplied to the spray head 6 through the storage tank 3, the pressure pump 4, and the connecting hose 5, allowing the spray head 6 to spray the surface. The device is then moved by pushing the handle at one end of the support frame 1. Simultaneously, the positioning wheel 10 rolls on the spraying surface. When the spraying height of the nozzle 6 needs to be adjusted, the motor 20 works, driving the second threaded rod 19 to rotate. The second threaded rod 19 drives the connecting block 18 to move within the inner wall of the middle part of the positioning frame 17. The height of the connecting block 18 is adjusted to adjust the height of the nozzle 6, thereby adjusting the spraying height of the nozzle 6. When the device needs to be stored after the spraying work is completed, the fixing plate 24 is pulled, causing one end of the positioning rod 21 to be pulled out from the inner wall of one end of the limiting plate 22. The connecting rod 9 is pushed, causing the connecting rod 9 to rotate and swing inside the U-shaped frame 801 through the rotating shaft 802 until the connecting rod 9 is engaged with the inside of the positioning card 16.
