Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying devices, in particular to a uniform paint spraying device for gate sheet metal accessories. Background Art

[0002] Uniform painting systems for gate sheet metal parts are often used for coating metal components with high surface requirements. These systems are designed to achieve a uniform application of paint, ensuring a consistent coating thickness and appearance on the finished workpiece. In sheet metal fabrication, the painting process not only enhances the component's aesthetics but also provides corrosion protection, extending the service life of the sheet metal component.

[0003] However, when the paint is stored in the barrel at the bottom of the spray gun, gravity affects the paint, resulting in inconsistent density between the top and bottom. This is because paint is typically a mixture of solid pigments, solvents, and additives. Since the density of pigment particles is generally greater than that of the solvent, under the influence of gravity, the pigment particles will gradually settle to the bottom of the barrel, while the lighter solvent tends to float on the top. This phenomenon is similar to sedimentation separation, and over time, a density difference will appear between the upper and lower layers of the paint. When the upper and lower densities of the paint are different, the coating thickness before and after spraying will be inconsistent, resulting in an uneven paint film. In view of this, we propose a uniform painting device for gate sheet metal accessories. Utility Model Content

[0004] The purpose of the utility model is to provide a uniform paint spraying device for gate sheet metal accessories, which solves the problem of inconsistent coating thickness and uniformity during spraying due to density differences in paint caused by gravity.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-8As shown, the utility model provides a technical solution: a uniform paint spraying device for gate sheet metal accessories, including a spray gun 1, a homogenizing mechanism 2 is provided at the bottom of the spray gun 1, the homogenizing mechanism 2 includes: a paint cup 21, the paint cup 21 is threadedly connected to the bottom of the spray gun 1, the bottom of the paint cup 21 is fixedly connected to a bottom connecting frame 22, the inner wall of the bottom connecting frame 22 is fixedly connected to the housing of a driving motor 23, the output shaft of the driving motor 23 is fixedly connected to a center disc 24, the outer wall of the center disc 24 is rotatably connected to the outer wall of the center disc 24. There is an outer ring 25, the outer wall of the center disk 24 is provided with a bottom outer gear ring 26, the inner wall of the outer ring 25 is provided with an inner gear ring 27, the bottom of the inner wall of the paint cup 21 is rotatably connected to a connecting gear 28, the top of the center disk 24 is fixedly connected to a connecting rod 1 29, the top of the outer ring 25 is fixedly connected to a connecting rod 210, the top of the connecting rod 1 29 is fixedly connected to an inner fan blade 211, and the top of the connecting rod 210 is fixedly connected to an outer fan blade 212; the inner wall of the paint cup 21 is provided with a scraping mechanism 3. Turn on the drive motor 23 to drive the center disc 24 to rotate forward, and the center disc 24 drives the connecting gear 28 to rotate reversely through the bottom outer ring gear 26. The connecting gear 28 drives the outer ring 25 to rotate reversely through the inner ring gear 27. At this time, the center disc 24 drives the inner fan blades 211 to rotate forward through the connecting rod 1 29, and the outer ring 25 drives the outer fan blades 212 to rotate reversely through the connecting rod 210. At this time, the inner fan blades 211 rotate forward to move the paint in the middle of the paint cup 21 downward, and the outer fan blades 212 rotate reversely to drive the paint around the paint cup 21 upward.

[0029] The scraping mechanism 3 includes a connecting frame 31, which is fixedly connected to the outer wall of the outer ring 25. The top of the connecting frame 31 is rotatably connected to the cleaning rod 32. The inner wall of the connecting frame 31 is provided with an inner ratchet 33. The bottom of the cleaning rod 32 is fixedly connected to a connecting cylinder 34. The inner wall of the connecting cylinder 34 is fixedly connected to one end of a return spring 35. The other end of the return spring 35 is fixedly connected to a pawl 36. The top of the inner wall of the paint cup 21 is fixedly connected to one end of a connecting spring 37. The other end of the connecting spring 37 is fixedly connected to a hemispherical cylindrical block 38. When the outer ring 25 rotates, it drives the connecting frame 31 to rotate, and the connecting frame 31 drives the cleaning rod 32 to rotate. While the cleaning rod 32 revolves along the inner wall of the paint cup 21, the friction between the paint cup 21 and the cleaning rod 32 causes it to rotate clockwise, causing the cleaning rod 32 to drive the connecting cylinder 34 to rotate clockwise. At this time, the connecting cylinder 34 drives the pawl 36 to rotate clockwise and slide with the inner ratchet 33. At this time, the cleaning rod 32 rolls and rubs the inner wall of the paint cup 21 to clean it.

[0030] The bottom of the outer ring 25 is rotatably connected to the inner wall of the paint cup 21, allowing the outer ring 25 to rotate stably. The connecting gear 28 is located within the inner wall cavity of the outer ring 25. The cavity between the outer ring 25 and the center disk 24 is a closed cavity that prevents paint from entering. The outer wall of the connecting gear 28 meshes with the outer wall of the bottom outer ring gear 26, and the outer wall of the connecting gear 28 meshes with the outer wall of the inner ring gear 27. When the bottom outer ring gear 26 rotates forward, it drives the connecting gear 28 to reverse, and the connecting gear 28 drives the inner ring gear 27 to reverse. The inner wall of the outer blade 212 is rotatably connected to the outer wall of the inner blade 211, allowing the outer blade 212 and the inner blade 211 to rotate stably with each other. Two connecting rods 1 29 and two connecting rods 210 are symmetrically provided, providing support and fixation.

[0031] The bottom of the connecting cylinder 34 is rotatably connected to the connecting frame 31, and the outer wall of the pawl 36 is slidably connected to the inner wall of the connecting cylinder 34, so that the pawl 36 can stably slide back and forth on the inner wall of the connecting cylinder 34. The outer wall of the hemispherical cylindrical block 38 is slidably connected to the inner wall of the paint cup 21, so that the hemispherical cylindrical block 38 can stably slide back and forth on the inner wall of the paint cup 21. There are several hemispherical cylindrical blocks 38, and the hemispherical cylindrical blocks 38 are arranged in a circular array.

[0032] The cleaning rod 32 continuously squeezes the hemispherical cylindrical block 38 when rotating. Under the action of the connecting spring 37, the hemispherical cylindrical block 38 continuously reciprocates and knocks, further preventing the paint from adhering.

[0033] The present invention provides a uniform paint spraying device for gate sheet metal fittings. When in use, paint is placed into a paint cup 21, and then a drive motor 23 is turned on to drive a central disc 24 in forward rotation. The central disc 24 drives a connecting gear 28 in reverse rotation via a bottom outer ring gear 26. The connecting gear 28 drives an outer ring 25 in reverse rotation via an inner ring gear 27. The central disc 24 then drives inner blades 211 in forward rotation via a connecting rod 1 29, and the outer ring 25 drives outer blades 212 in reverse rotation via a connecting rod 210. The inner blades 211 rotate forward, moving the paint in the center of the paint cup 21 downward, while the outer blades 212 rotate in reverse, moving the paint around the paint cup 21 upward. This design effectively prevents pigment particles in the paint cup 21 from settling to the bottom due to gravity and the solvent from floating up, resulting in density differences. Through this up-and-down circulation, the paint is always evenly mixed, thereby maintaining a consistent and uniform coating thickness during the spraying process, avoiding uneven spraying due to density differences, and achieving a uniform spraying effect.

[0034] When the outer ring 25 rotates, it drives the connecting frame 31 to reverse, and the connecting frame 31 drives the cleaning rod 32 to reverse. While the cleaning rod 32 revolves along the inner wall of the paint cup 21, due to the friction between the paint cup 21 and the cleaning rod 32, it also rotates clockwise, so that the cleaning rod 32 drives the connecting cylinder 34 to rotate clockwise. At this time, the connecting cylinder 34 drives the pawl 36 to rotate clockwise and slide with the inner ratchet 33. At this time, the cleaning rod 32 rolls and rubs the inner wall of the paint cup 21 to clean it, avoiding the paint adhering to the inner wall of the paint cup 21 and causing uneven paint, thereby further enhancing the homogenization effect of the paint.

[0035] When the inner wall of the paint cup 21 needs to be cleaned, the driving motor 23 reverses, and the outer ring 25 rotates forward, driving the connecting frame 31 to rotate forward, and the connecting frame 31 drives the cleaning rod 32 to rotate forward. While the cleaning rod 32 revolves along the inner wall of the paint cup 21, due to the friction between the paint cup 21 and the cleaning rod 32, it also rotates counterclockwise, so that the cleaning rod 32 drives the connecting cylinder 34 to rotate counterclockwise, and the connecting cylinder 34 drives the pawl 36 to rotate counterclockwise. The pawl 36 then contacts the inner ratchet 33, so that the cleaning rod 32 cannot rotate on its own. The cleaning rod 32 and the inner wall of the paint cup 21 generate static friction, which increases the friction and also improves the cleaning effect.
