[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] 1. Through the design of the spraying mechanism, the motor drives the stirring blades to agitate the paint, and during the agitation process, the stirring blades rotate to enhance the agitation effect. The steam generator emits steam, which is then used to heat the paint through the heat pipe. This allows the paint to be acted on from different angles and with different intensities, ensuring that the pigments, resins, solvents, and other components in the paint are fully mixed, preventing layering, sedimentation, or agglomeration. This helps to ensure the consistency and quality of the paint applied to the roller nails. Heating can also reduce the viscosity of the paint, making it more fluid and easier to agitate and spray. This helps to reduce clogging and dripping of the paint during the spraying process, improving spraying efficiency. The treated paint is transported to the spray gun through a spiral conveyor plate, making the amount of paint sprayed from the spray gun more uniform. When spraying stops, the spiral conveyor plate can be stopped directly, so that no more paint is transported in the pipeline, thus avoiding the clogging caused by residual paint in the spray gun.

[0025] 2. Through the setting of the cleaning conveyor mechanism, the cylinder drives the coil nail to the appropriate spraying position, and the motor drives the cleaning brush to clean the dust on the coil nail. This allows the surface of the coil nail to better absorb the paint, making the paint film more uniform and avoiding differences in protective performance caused by local paint film being too thin or too thick.

[0032] Example 1

[0033] like Figures 1-3 As shown, the present invention proposes a coil nail painting device, which includes a conveyor table 1, a processing channel 2 set on the top of the conveyor table 1, a cleaning conveyor mechanism, a painting mechanism, and a stirring blade 509.

[0034] The cleaning conveyor is installed in the processing channel 2 to transport the coil nails and remove dust and impurities from the coil nails during transportation.

[0035] The painting mechanism is set on the processing channel 2 and is used to stir and heat the paint, while spraying the paint evenly from four directions.

[0036] A stirring blade 509 is mounted on a painting mechanism. An air blowing pipe 508 is located at the center of the stirring blade 509, and a heat-conducting pipe 510 is located on the outer side of the stirring blade 509. The air blowing pipe 508 is a hollow pipe used to circulate steam. Multiple through holes are provided on the air blowing pipe 508 to allow the internal steam to enter the heat-conducting pipe 510. The heat-conducting pipe 510 will provide heat to the paint when the stirring blade 509 is stirring the paint.

[0037] A UV lamp 3 is installed on the inner side of the processing channel 2. There are two UV lamps 3 symmetrically arranged about the processing channel 2. The UV lamp 3 is used to dry the paint after the coil nail is painted. At the same time, the airflow will not be blown during the drying process to avoid blowing the paint on the coil nail and affecting the uniformity of the spraying.

[0038] The cleaning conveying mechanism includes an electric sliding frame 401, a cylinder 402, a push rod 403, an electromagnetic plate 404, and a cleaning component. The electric sliding frame 401 is slidably disposed inside the conveyor table 1. The cylinder 402 is disposed at the bottom of the electric sliding frame 401. The push rod 403 is disposed at the output end of the cylinder 402. The electromagnetic plate 404 is disposed at the top of the push rod 403. The electric sliding frame 401 drives the cylinder 402 to transport the coil nail forward at a uniform speed on the conveyor table 1. The coil nail is placed on the electromagnetic plate 404, and the cylinder 402 is activated. The cylinder 402 drives the coil nail to move up and down through the push rod 403, so that it is located at the center of the painting height. The cleaning component is disposed inside the processing channel 2 and is used to clean the coil nail. The cleaning assembly includes a second motor 405, a second rotating shaft 406, a connecting plate 407, and a telescopic tube 408. The second motor 405 is located at the top of the processing channel 2, the second rotating shaft 406 is located at the output end of the second motor 405, the bottom of the second rotating shaft 406 is provided with the connecting plate 407, the top of the connecting plate 407 is provided with the telescopic tube 408, the outer side of the telescopic tube 408 is provided with the spring 409, the bottom of the telescopic tube 408 is provided with the cleaning brush 410, and the outer side of the cleaning brush 410 is provided with the guide platform. When the second motor 405 is started, the second motor 405 drives the connecting plate 407 to rotate through the second rotating shaft 406, and the connecting plate 407 drives the cleaning brush 410 to rotate through the telescopic tube 408, thereby cleaning the coil nails from all directions. At the same time, since the cylinder 402 adjusts the coil nails to different heights, the coil nails contact the guide ring 411, causing the guide ring 411 to move, thereby changing the position of the cleaning brush 410, and thus cleaning the coil nails at different heights.

[0039] Example 2

[0040] like Figures 4-5 As shown, this utility model proposes a roller nail painting device. Compared with Embodiment 1, this embodiment details the structure of the painting mechanism.

[0041] The painting mechanism includes a paint processing component and a painting component; the paint processing component is located at the top of the processing channel 2 and is used to stir and heat the paint; the painting component is located at the bottom of the paint processing component and is used to extract the processed paint and spray it onto the roller nail. The paint processing assembly includes a support rod 501, a paint bucket 502, a fixing box 503, and a motor 504. The support rod 501 is located at the top of the processing channel 2, the paint bucket 502 is located at the top of the support rod 501, the fixing box 503 is located at the top of the paint bucket 502, and the motor 504 is located at the top of the fixing box 503. An output pipe 506 is provided on the side of the fixing box 503, and a steam generator 505 is provided at the end of the output pipe 506 away from the fixing box 503. A rotating shaft 507 is provided at the output end of the motor 504. The outer side of the rotating shaft 507 is rotatably connected to the end of the air blowing pipe 508. The inner side of the rotating shaft 507 is hollow. A bevel gear 511 is provided at the end of the air blowing pipe 508 away from the rotating shaft 507. A gear ring 512 meshes with the bottom of the bevel gear 511, and the side of the gear ring 512 is connected to the inner side of the paint bucket 502. The painting assembly includes a connecting shaft 513, a spiral conveyor plate 514, and a feeding pipe 515. The connecting shaft 513 is located at the bottom of the rotating shaft 507, the spiral conveyor plate 514 is located on the outside of the connecting shaft 513, and the feeding pipe 515 is located at the bottom of the paint tank 502. The inner side of the feeding pipe 515 is in contact with the outer side of the spiral conveyor plate 514. An inlet pipe 516 is located at the bottom of the feeding pipe 515, and a spray gun 517 is located at the end of the inlet pipe 516 away from the feeding pipe 515. The motor 504 drives the rotating shaft 507 to rotate, and the rotating shaft 507 passes through... The air blowing pipe 508 drives the stirring blade 509 to agitate the paint. At the same time, the air blowing pipe 508 drives the bevel gear 511 to rotate around the paint tank 502. During the rotation, the bevel gear 511 meshes with the gear ring 512, so the bevel gear 511 rotates on its own axis, which in turn drives the air blowing pipe 508 and the stirring blade 509 to rotate on their own axis. The spraying direction of the spray gun 517 is at a 45-degree angle to the axis of the feed pipe 515. Four spray guns 517 are arranged in a ring around the feed pipe 515, which spray paint on the front left, rear left, front right and rear right of the coil nail respectively.

[0042] In summary, when using this invention, the motor 504 and steam generator 505 are started. The motor 504 drives the rotating shaft 507 to rotate. The rotating shaft 507 drives the stirring blade 509 to agitate the paint through the air blowing pipe 508. At the same time, the air blowing pipe 508 drives the bevel gear 511 to rotate around the paint tank 502. During the rotation, because the bevel gear 511 and the gear ring 512 mesh, the bevel gear 511 rotates on its own axis, which in turn drives the air blowing pipe 508 and the stirring blade 509 to rotate, thus enhancing the agitation effect. The steam generator 505 generates steam, which is blown into the heat-conducting pipe 510 through the rotating shaft 507 and the air blowing pipe 508. The heat-conducting pipe 510 heats the paint being agitated. The processed paint is transported to the feeding pipe 515 through the spiral conveyor plate 514, and then enters the spray nozzle through the inlet pipe 516. Inside gun 517, the coil nail is placed on electromagnetic plate 404. Cylinder 402 and motor 405 are activated, driving push rod 403 to move. Push rod 403 moves the coil nail to an appropriate height via electromagnetic plate 404. Electric sliding frame 401 moves the coil nail on conveyor table 1. Motor 405 drives connecting plate 407 to rotate via rotating shaft 406. Connecting plate 407 drives cleaning brush 410 to rotate via telescopic tube 408. When the cleaning brush 410 moves to the appropriate position, guide ring 411 contacts electromagnetic plate 404 and moves upward, allowing cleaning brush 410 to clean the coil nail from all directions. After cleaning, the coil nail moves to spray gun 517. Spray gun 517 sprays paint on the front left, rear left, front right, and rear right of the coil nail. After spraying, UV lamp 3 dries the paint on the coil nail.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
