The spraying body and the mixing body are connected by an extraction device. A fixing frame is set on the side of the spraying body away from the mixing body, and two application components are set on one side of the fixing frame. The two application components are arranged perpendicularly opposite each other, and the application body is located between the two application components. The above patent has the following shortcomings: Although the distance between the application roller and the wall can be adjusted, in actual use, when encountering uneven walls, the operator still needs to manually adjust it. This process is slow, cannot achieve continuous wall spraying, and cannot quickly adjust the distance between the application roller and the wall, affecting the uniformity of the paint surface. Furthermore, the manual adjustment response is sluggish, and fluctuations in the distance can easily lead to unstable spray flow, reducing the efficiency and quality of interior decoration spraying. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when applying paint to a wall surface using a paint roller after spraying, it is impossible to quickly adjust the distance between the paint roller and the wall surface according to the unevenness of the wall surface. Therefore, this invention proposes an interior decoration and renovation spraying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An interior decoration spraying device includes a mobile cart equipped with a spray nozzle, a hand handle slidably connected to the mobile cart, a mounting plate fixedly connected to the hand handle, two application rollers rotatably connected to the mounting plate, and two rotating cylinders rotatably connected to the mounting plate. Each of the two rotating cylinders is threadedly connected to an adjusting rod, and a guide rod is slidably connected to the mounting plate. The application rollers are rotatably mounted between the adjusting rods and the guide rods.

[0007] Preferably, a mixing tank is fixedly installed on the mobile vehicle, a pump is fixedly installed on the mobile vehicle, a water pumping pipe is fixedly connected between the pump and the mixing tank, and an inlet pipe is fixedly connected between the other end of the pump and the nozzle.

[0008] Preferably, two first servo motors are symmetrically fixedly installed on one side of the mounting plate, and the output ends of the two first servo motors are respectively fixedly connected to two rotating drums. The rotating drums are provided with threads corresponding to the adjusting rods.

[0009] Preferably, a sliding groove is provided on one end surface of both the adjusting rod and the guide rod, and a slider is slidably connected in the sliding groove of both the adjusting rod and the guide rod, and a sliding rod is fixedly connected to each of the two sliders.

[0010] Preferably, the inner walls of the grooves of the adjusting rod and the guide rod are provided with sliding holes corresponding to the sliding rods, and springs are sleeved on both sliding rods, with the two ends of the springs abutting against the inner walls of the grooves of the slider, the guide rod and the adjusting rod respectively.

[0011] Preferably, the two applicator rollers are rotatably connected to two sets of sliders, and a protective cover corresponding to the applicator roller is fixedly connected to the slider.

[0013] Preferably, the movable block has an insertion hole, and the hand-held rod is inserted into the insertion hole.

[0014] Compared with the prior art, this utility model provides an indoor decoration and finishing spraying device, which has the following beneficial effects:

[0015] 1. This interior decoration spraying device can drive the drum to rotate by starting the first servo motor. Under the guidance of the guide rod, the adjusting rod slides horizontally, which in turn drives the coating roller to move, so that the adjusting rod extends or retracts, automatically adjusting the distance between the coating roller and the wall to adapt to walls that are not on the same plane. Compared with traditional manual adjustment, it is faster and more convenient.

[0016] 2. This interior decoration spraying device uses springs to ensure that the two coating rollers remain in close contact with the wall surface at all times.

[0017] 3. This interior decoration and finishing spraying device allows the operator to move to a higher position by inserting a handheld rod into the socket of the moving block. The operator then moves to a higher position and simply starts the second servo motor to rotate the screw, causing the moving block to slide stably upward within the rectangular slot plate. This automatically moves the handheld rod upward to a higher position, eliminating the need for manual hand-held movement of the spray nozzle. This avoids the inconvenience of operating at heights, reduces the risk of the spray nozzle falling, and allows the handheld rod to be inserted into the socket of the moving block without continuous hand-held movement, thus reducing labor intensity.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-8 An interior decoration spraying device includes: a mobile cart 1 equipped with a spray head 2; a hand handle 3 slidably connected to the mobile cart 1; a mounting plate 4 fixedly connected to the hand handle 3; two application rollers 5 rotatably connected to the mounting plate 4; and two rotating drums 6 rotatably connected to the mounting plate 4. Adjusting rods 7 are threadedly connected to the interior of each rotating drum 6. A guide rod 8 is slidably connected to the mounting plate 4. The application rollers 5 are rotatably mounted between the adjusting rods 7 and the guide rods 8. By using the hand handle 3 to align the mounting plate 4 and the spray head 2 with the wall surface to be sprayed, the two application rollers 5 are then brought into contact with the wall surface for spraying. The rolling of the two application rollers 5 ensures that the paint on the wall surface is evenly applied. When rolling onto a non-horizontal wall surface, the operator only needs to rotate one of the rotating drums 6 to extend or retract the adjusting rod 7, adjusting the distance between the application roller 5 and the wall surface to adapt to the non-plane wall surface. Compared to traditional manual adjustment, this method is faster and more convenient.

[0030] A mixing tank 9 is fixedly installed on the mobile vehicle 1, and a pump 10 is also fixedly installed on the mobile vehicle 1. A water pumping pipe 21 is fixedly connected between the pump 10 and the mixing tank 9. An inlet pipe 22 is fixedly connected between the other end of the pump 10 and the nozzle 2. By starting the pump 10, the paint in the mixing tank 9 can be drawn into the nozzle 2 for spraying on the wall. The mixing tank 9 can automatically stir the paint. Usually, a drive motor drives the stirring rod to stir the raw materials in the mixing tank 9, so that the sprayed paint is more uniform and of better quality.

[0031] Two first servo motors 11 are symmetrically fixedly installed on one side of the mounting plate 4. The output ends of the two first servo motors 11 are respectively fixedly connected to two rotating drums 6. The rotating drums 6 have threads corresponding to the adjusting rods 7. By starting the first servo motors 11, the rotating drums 6 can be driven to rotate. Under the guidance of the guide rods 8, the adjusting rods 7 slide horizontally, thereby driving the coating rollers 5 to move.

[0032] Both the adjusting rod 7 and the guide rod 8 have a sliding groove on one end surface. A slider 12 is slidably connected in the sliding groove of both the adjusting rod 7 and the guide rod 8. A slider 13 is fixedly connected to each of the two sliders 12.

[0033] Both the adjusting rod 7 and the guide rod 8 have corresponding sliding holes on their inner walls. Springs 14 are fitted onto both slide rods 13. The two ends of the springs 14 abut against the inner walls of the sliding grooves of the slider 12, guide rod 8, and adjusting rod 7, respectively. When the applicator roller 5 abuts against the wall, extending the adjusting rod 7 allows the applicator roller 5 to slide the slider 12 within the grooves of the adjusting rod 7 and guide rod 8, compressing the springs 14. The springs 14 ensure a tight fit between the applicator roller 5 and the wall. This tight fit ensures that the applicator roller 5 applies uniform pressure to any area of ​​the wall, preventing missed areas or uneven coating thickness due to localized gaps or suspension. It also prevents paint splashing, dripping, or excessive penetration due to gaps. Furthermore, it reduces the risk of loss of control due to arm fatigue during high-altitude operations, lowering labor intensity and improving operational safety.

[0034] Two coating rollers 5 are rotatably connected to two sets of sliders 12. Protective covers 20 corresponding to the coating rollers 5 are fixedly connected to the sliders 12. A rectangular groove plate 15 is fixedly connected to the moving carriage 1. A screw 16 is rotatably connected inside the rectangular groove plate 15. A moving block 17 is threadedly connected to the screw 16. The protective cover 20 can reduce paint splashing when the coating rollers 5 are rolling.

[0035] A second servo motor 18 is fixedly installed on the top of the rectangular slot plate 15. The output end of the second servo motor 18 is fixedly connected to the screw 16, and the moving block 17 is slidably connected inside the rectangular slot plate 15.

[0036] The movable block 17 has a socket 19, and the hand lever 3 is inserted into the socket 19. When it is necessary to spray the wall at a high place, the operator can insert the hand lever 3 into the socket 19 of the movable block 17. Then the operator moves to the high place. By starting the second servo motor 18, the screw 16 can be rotated, which drives the movable block 17 to slide upward stably in the rectangular slot plate 15, thereby automatically moving the hand lever 3 upward to the high place. There is no need to manually move the spray head 2 to the high place, avoiding the inconvenience of operation when climbing, reducing the risk of the spray head 2 falling, and the hand lever 3 can also be inserted into the socket 19 of the movable block 17 without continuous hand holding, reducing labor intensity. After the spraying is completed, the hand lever 3 can be directly inserted into the socket 19.

[0037] In this invention, during spraying operations, the operator moves the spray head 2 to a suitable position using the moving cart 1. Then, the operator pulls the hand lever 3 out of the insertion hole 19, starts the mixing tank 9 and the extraction pump 10, and then makes the two coating rollers 5 contact the wall surface to perform the spraying operation. When it is necessary to adjust the distance between the coating rollers 5 and the wall surface for thick or light coating, simply start the first servo motor 11 to drive the rotating drum 6 to rotate, which will cause the adjusting rod 7 to slide and move the coating rollers 5 to adjust the distance between the spray head 2 and the wall surface. When encountering an uneven wall surface, one or both adjusting rods 7 can be adjusted to adapt to the uneven wall surface. The spring 14 ensures that the two coating rollers 5 are always in close contact with the wall surface.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
