[0027] Example 1

[0028] A rust-preventive spraying device for stainless steel processing, such as Figures 1 to 5 As shown, the system includes a frame 1, with a conveyor belt 2 installed on the inner wall of the bottom of the frame 1. A cleaning component 3 and a spraying component 4 are sequentially arranged on the frame 1 along the movement direction of the conveyor belt 2. A heating ring is provided between the cleaning component 3 and the spraying component 4. The cleaning component 3 includes a connecting frame 5 and a photoelectric gate 6, which are fixed to the inner wall of the frame 1 and are positioned opposite each other. The photoelectric gate 6 is installed on one side of the two connecting frames 5. A sweeping roller 8 is rotatably connected to each of the two connecting frames 5 on their opposite sides. A drive mechanism for rotating the sweeping roller 8 is provided on the outer side of the frame 1. The drive mechanism can be an existing mature technology such as a motor. Multiple cleaning directions are provided on one side of the sweeping roller 8. The roller 8 has a nozzle 7. The frame 1 has a water storage chamber 10 inside. Multiple nozzles 7 are installed on the same pipe through electric valves. One end of the pipe is connected to the water storage chamber 10 through a water pump. Two connecting frames 5 are provided with scrapers 9 opposite each other at the ends away from the photoelectric gate 6. The scrapers 9 are conical and the tips of the scrapers 9 face the photoelectric gate 6. The outer wall of the lower connecting frame 5 has a through hole 11 that communicates with the water storage chamber 10. The through hole 11 is located on one side of the scraper 9. A fixing frame 12 is fixed to the inner wall of the water storage chamber 10. A filter box 13 is slidably connected to the inner wall of the fixing frame 12. The opening of the filter box 13 is located below the through hole 11.

[0029] The spraying assembly 4 includes a connecting frame 2 14 and a spray head 2 15. The connecting frame 2 14 is fixed to the inner wall of the frame 1. Multiple spray heads 2 15 are installed on opposite sides of the connecting frame 2 14 via electric valves. The frame 1 is provided with a paint storage chamber 19. A paint delivery pump is installed inside the paint storage chamber 19. The output end of the paint delivery pump is connected to a delivery pipe that communicates with multiple spray heads 2 15.

[0030] During operation, the stainless steel plate is conveyed by the conveyor belt 2 through the cleaning component 3 and the spraying component 4 in sequence. When passing through the cleaning component 3, the photoelectric gate 6 detects the width of the stainless steel plate and controls the opening and closing of the electric valves in the cleaning component 3 and the spraying component 4. The width of water spraying and paint spraying is controlled according to the width of the stainless steel plate. Then, the stainless steel plate passes between two cleaning rollers 8. The drive mechanism drives the cleaning rollers 8 to rotate and clean the stainless steel plate. The nozzle 7 sprays water at the contact point between the cleaning rollers 8 and the stainless steel plate. The water carries the dirt cleaned and flows back into the water storage chamber 10 through the through hole 11. The fixing frame 12 filters and purifies the water. Then, the scraper 9 scrapes off the residual water on the surface of the stainless steel plate. The residual water gathers on both sides of the stainless steel plate and then flows into the through hole 11. After cleaning, the stainless steel plate is first electrically heated by the heating ring to raise the temperature of the stainless steel plate and remove the residual water on the surface of the stainless steel plate. Then, the stainless steel plate is conveyed by the conveyor belt 2 between the nozzles 15 for painting. The high temperature of the stainless steel plate itself will accelerate the drying speed of the paint.

[0031] The cleaning component 3 is installed to clean the surface of the stainless steel plate, preventing dirt from affecting the adhesion of the paint on the stainless steel plate.

[0032] By installing a photoelectric gate 6, in conjunction with an electric valve, the width of water spraying and paint spraying can be controlled, achieving automatic adjustment according to the width of the conveyed steel plate.

[0033] Example 2

[0034] A rust-preventive spraying device for stainless steel processing. This embodiment is based on Embodiment 1 and makes the following improvements, such as... Figure 4 As shown, the connecting frame 14 has a cavity 16 located on one side of the nozzle 15. Both cavities 16 have air outlets on opposite sides. The inner wall of the cavity 16 is fitted with a heating wire 17, and a fan 18 is provided on one side of the heating wire 17.

[0035] After the painting is completed, the fan 18 blows air onto the stainless steel surface. When the air passes through the heating wire 17, the heating wire 17 heats the air, and the hot air accelerates the drying of the paint.

[0036] By setting up a cavity 16, a heating wire 17, and a fan 18, after the painting is completed, the fan 18 blows air onto the stainless steel surface. When the air passes through the heating wire 17, the heating wire 17 heats the air, and the hot air further accelerates the drying of the paint.

[0037] Working principle: During operation, the stainless steel plate is conveyed by the conveyor belt 2 through the cleaning component 3 and the spraying component 4 in sequence. When passing through the cleaning component 3, the photoelectric gate 6 detects the width of the stainless steel plate and controls the opening and closing of the electric valves in the cleaning component 3 and the spraying component 4. The width of water spraying and paint spraying is controlled according to the width of the stainless steel plate. Then, the stainless steel plate passes between two cleaning rollers 8. The drive mechanism drives the cleaning rollers 8 to rotate, cleaning the stainless steel plate. The nozzle 7 sprays water at the contact point between the cleaning rollers 8 and the stainless steel plate. The water flow carries the cleaned dirt back into the water storage chamber 10 through the through hole 11. The fixing frame 12 controls the water flow. After filtration and purification, the scraper 9 removes residual moisture from the surface of the stainless steel plate. The residual moisture gathers on both sides of the stainless steel plate and then flows into the through hole 11. The cleaned stainless steel plate is first electrically heated by the heating ring to raise the temperature of the stainless steel plate and remove residual moisture from the surface of the stainless steel plate. Then, the stainless steel plate is conveyed by the conveyor belt 2 and passes between the spray nozzles 15 for painting. After the painting is completed, the fan 18 blows air onto the stainless steel surface. When the air passes through the heating wire 17, the heating wire 17 heats the air, and the hot air accelerates the drying of the paint. The high temperature of the stainless steel plate itself will accelerate the drying speed of the paint.
