Description

Technical Field

[0001] This utility model relates to the field of waterproof coating spraying technology, and in particular to a device for uniformly spraying waterproof coating. Background Technology

[0002] Waterborne polyurethane waterproof coating is a chemically reactive material, a water-soluble polymer compound waterproof coating obtained by the reaction of various polymer resins. When used, the material is directly brushed onto the waterproof substrate, where it cross-links and cures to form a rubber-like elastic film, thus achieving waterproofing. This product has excellent waterproofing effect; after curing, the coating forms a seamless, complete, elastic waterproof layer with high strength and elongation. It is highly adaptable to substrate cracking or expansion, and exhibits excellent elongation and aging resistance. It also possesses excellent freeze-thaw resistance and low-temperature flexibility, and its performance is stable under ultraviolet light, heat, light, and oxygen, resulting in a long service life.

[0003] Traditional waterproof coatings are mostly applied manually. Workers are prone to uneven application, resulting in inconsistent coating thickness on the surface of the object. Furthermore, manual application is inefficient and time-consuming. Utility Model Content

[0004] To overcome the shortcomings of uneven application and low efficiency of traditional manual spraying methods, the technical problem to be solved is to provide a device for uniform spraying of waterproof coatings.

[0005] A waterproof coating uniform spraying device includes an L-shaped bracket, a controller, a support frame, a motor, a rotating rod, and a rotating plate. The controller is installed on the right side of the middle of the L-shaped bracket, and the support frame is fixedly connected to the top right side of the L-shaped bracket. The motor is installed at the bottom inside the support frame. The output shaft of the motor is connected to the rotating rod, and the top of the rotating rod is fixedly connected to the rotating plate, which is rotatably connected to the top of the support frame.

[0006] Furthermore, it also includes a placement frame, which is connected to the top center of the rotating plate.

[0007] Furthermore, it also includes a baffle, with a baffle fixed to the outer right side wall of the support frame.

[0008] Furthermore, it also includes a support plate, a material frame, a cover plate, a second motor, a second rotating rod, a stirring paddle, a pump body, and a nozzle. The support plate is fixed to the upper right side of the L-shaped bracket, and the material frame passes through the right side of the support plate. The top of the material frame is rotatably connected to the cover plate. The second motor is installed in the middle of the top of the material frame. The output shaft of the second motor passes through the top of the material frame and is connected to the second rotating rod. Several stirring paddles are fixed to the outer wall of the second rotating rod. The pump body is installed on the outer wall of the right side of the material frame. The nozzle is connected to the right side of the pump body, and the nozzle position is parallel to the placement frame. The controller is electrically connected to the first motor, the second motor, and the pump body.

[0009] Furthermore, both the placement frame and the nozzle are detachable.

[0010] Furthermore, multiple small holes are provided on the right side of the nozzle to further subdivide and atomize the paint pumped out by the pump.

[0011] The beneficial effects are as follows: 1. By setting up a motor, a rotating plate and a placement frame that are coordinated and controlled by a controller, the workpiece can rotate at a uniform speed, ensuring that the paint sprayed from the nozzle can evenly cover all surfaces of the workpiece. This effectively solves the problem of uneven coating thickness caused by unstable moving speed and angle in manual spraying, and achieves a uniform coating effect.

[0012] 2. This utility model integrates a second motor, a second rotating rod, and a stirring paddle within the material frame, enabling continuous mechanical stirring of the coating before spraying. This prevents the separation of components due to precipitation of polymer compounds, ensuring the uniformity and stability of the coating properties and laying a material foundation for forming a complete, high-performance elastic waterproof layer.

[0013] 3. This utility model achieves stable delivery and fine atomization of paint by combining a pump body with a nozzle with multiple small holes. At the same time, the baffle effectively blocks splashing, reducing material waste. The whole device replaces manual operation with mechanized operation, which significantly improves the efficiency and consistency of spraying operations and reduces time and labor costs.

Detailed Implementation Example

[0019] A waterproof coating uniform spraying device, such as Figures 1-3As shown, it includes an L-shaped bracket 1, a controller 2, a support frame 3, a motor 4, a rotating rod 5, and a rotating plate 6. The controller 2 is installed on the right side of the middle of the L-shaped bracket 1. The support frame 3 is fixedly connected to the top right side of the L-shaped bracket 1. The motor 4 is fixedly installed at the bottom inside the support frame 3. The output shaft of the motor 4 is connected to the rotating rod 5. The rotating plate 6 is fixedly connected to the top of the rotating rod 5 and is rotatably connected to the top of the support frame 3. It also includes a placement frame 7. The placement frame 7 is connected to the middle of the top of the rotating plate 6. It also includes a baffle 8. The baffle 8 is fixedly connected to the outer right side wall of the support frame 3. The placement frame 7 and the nozzle 16 are both detachable.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a support plate 9, a material frame 10, a cover plate 11, a second motor 12, a second rotating rod 13, a stirring paddle 14, a pump body 15, and a nozzle 16. The support plate 9 is fixed to the upper right side of the L-shaped bracket 1. The material frame 10 passes through the right side of the support plate 9. The cover plate 11 is rotatably connected to the top of the material frame 10. The second motor 12 is fixedly installed in the middle of the top of the material frame 10. The output shaft of the second motor 12 passes through the top of the material frame 10 and is connected to the second rotating rod 13. Several stirring paddles 14 are fixed to the outer wall of the second rotating rod 13. The pump body 15 is installed on the right outer wall of the material frame 10. The nozzle 16 is connected to the right side of the pump body 15 and is parallel to the placement frame 7. The controller 2 is electrically connected to the first motor 4, the second motor 12, and the pump body 15. The nozzle 16 has multiple small holes on its right side, which can subdivide and atomize the paint pumped out by the pump body 15.

[0021] When using this waterproof coating uniform spraying device, the operator first places the workpiece to be sprayed securely in the placement frame 7 at the top of the rotating plate 6. Then, the operator opens the cover plate 11 at the top of the material frame 10 and pours the pre-mixed water-based polyurethane waterproof coating into the material frame 10. After adding the material, the cover plate 11 must be closed again to ensure that the material frame 10 remains sealed during subsequent mixing to prevent foreign matter from entering or coating from splashing. After preparation, the operator starts the device through the controller 2 installed on the right side of the middle of the L-shaped bracket 1. The controller 2 first controls the motor 12 to start working, and the output of the motor 12... The shaft drives the rotating rod 13 to rotate, and multiple stirring paddles 14 fixed to the outer wall of the rotating rod 13 continuously and evenly stir the coating in the material frame 10. This process is crucial, as it effectively prevents the precipitation or separation of various polymer resins in the coating, ensuring the uniformity of the material composition. This lays the foundation for the subsequent formation of a high-quality, stable, elastic waterproof coating. After stirring for a period of time and confirming that the coating has reached the required uniform state for construction, the operator can start the pump body 15 and motor 4 through the controller 2. The pump body 15 then begins to work, continuously stirring the uniformly stirred coating in the material frame 10. The pump outputs a stable mist jet through the nozzle 16 connected to its right side, spraying it onto the workpiece inside the placement frame 7. Simultaneously, motor 4 starts, its output shaft driving the rotating rod 5 to rotate at a constant speed. The rotating rod 5 drives the rotating plate 6 and the placement frame 7 to rotate slowly and smoothly together. The workpiece placed inside the placement frame 7 thus achieves a uniform rotational motion around its axis. This design ensures that all outer surfaces of the workpiece can sequentially and cyclically pass through the spraying area in front of the nozzle 16, allowing the atomized paint to evenly cover every part of the workpiece. This overcomes the limitations of manual spraying due to fixed angles or slow movement speeds. The uneven coating thickness, omissions, or excessive thickness in certain areas caused by inconsistent coating thickness are addressed by the baffle 8 fixed to the right outer wall of the support frame 3, which plays an important protective role. It effectively prevents paint from splashing or rebounding during the spraying process, while maintaining the cleanliness of the working environment and reducing unnecessary material waste. After the spraying operation is completed, the operator shuts off all power units through the controller 2. Then, the uniformly coated workpiece can be removed from the placement frame 7 for curing. The placement frame 7 and the nozzle 16 can be disassembled for thorough cleaning and maintenance in preparation for the next use. At this point, the spraying of the workpiece is complete.
