The oil pump 18 is located at one side of the bottom of the inner surface of the oil receiving box 9, and a mounting plate 17 fixed to the inner surface of the oil receiving box 9. Nozzles are fixed to the surface of the mounting plate 17. Several groups of nozzles are equidistantly fixed on the surface of the mounting plate 17. The nozzles are located at one side of the bottom of the strip 10. The rust preventive oil can be sprayed onto the surface of the strip 10 through the nozzles. The oil pump 18 and the mounting plate 17 are connected by an oil delivery pipe. The oil pump 18 can pump the rust preventive oil inside the oil receiving box 9 into the inside of the mounting plate 17 and spray it out through the nozzles fixed on the surface of the mounting plate 17. A second scraper 16 is fixed to the inner surface of the oil receiving box 9. The second scraper 16 is located on one side of the mounting plate 17. The top of the second scraper 16 contacts the surface of the strip 10. The second scraper 16 can scrape off the excess rust preventive oil sprayed onto the surface of the strip 10 by the nozzles on the surface of the mounting plate 17 and evenly smear the rust preventive oil on the surface of the strip 10. The excess rust preventive oil will fall back into the inside of the oil receiving box 9 through the surface of the second scraper 16. Nozzles 11 fixed to the bottom of the oil storage tank 7.

The sealing ring 22 is located at the bottom of the gasket 21. When there is no external force interference, the spring 20 will push the gasket 21 to move so that the bottom of the gasket 21 contacts the surface of the sealing ring 22, thereby making the gasket 21 and the sealing ring 22 relatively sealed. A connecting rod 23 fixed to the bottom of the gasket 21. When the connecting rod 23 moves, it will drive the fixed gasket 21 to move.
[0022] Working principle: When it is necessary to perform oil mist anti-rust treatment on the surface of the strip 10 sent out from one end of the outlet of the rolling mill 1, the driving motor drives the first support arm 2 to rotate. When the first support arm 2 rotates, it drives the first driving wheel 4 to rotate. When the first driving wheel 4 rotates, it drives the third driving wheel 13 to rotate through the synchronous toothed belt 12. When the third driving wheel 13 rotates, it drives the second driving wheel 14 to rotate, so that the second driving wheel 14 drives the second support arm 3 to rotate. When the second support arm 3 rotates, it drives the oil receiving box 9 to move and makes the oil receiving box 9 move to one side at the bottom of the strip 10. When the first support arm 2 rotates, it drives the guide shaft 6, the oil storage bin 7 and the first scraping plate 8 to move, so that the surface of the guide shaft 6 contacts the surface of the strip 10. The guide shaft 6 can be used to assist in guiding the strip 10, so that the strip 10 moves to the side close to the winding shaft 5. At the same time, the bottom of the first scraping plate 8 also contacts the surface of the strip 10. When the bottom of the first scraping plate 8 contacts the surface of the strip 10, the bottom of the connecting rod 23 will contact the surface of the strip 10 and move itself through the extrusion on the surface of the strip 10. When the connecting rod 23 moves, it drives the fixed sealing gasket 21 to move, so that the surface between the sealing gasket 21 and the sealing ring 22 is no longer in contact. Thus, the anti-rust oil inside the oil storage bin 7 can flow out through the gap between the sealing ring 22 and the connecting rod 23 and flow to the surface of the strip 10 through the surface of the connecting rod 23. When the strip 10 moves and drives the anti-rust oil to pass through the bottom of the first scraping plate 8, the first scraping plate 8 will scrape off the excess anti-rust oil on the surface of the strip 10 and evenly smear the anti-rust oil on the surface of the strip 10. The excess anti-rust oil will flow to both ends of the first scraping plate 8 and fall back into the interior of the oil receiving box 9 through the surface of the first scraping plate 8, thus avoiding the waste of anti-rust oil dripping to the ground and the dirt on the ground. At the same time, when the oil receiving box 9 moves to the bottom of the strip 10, the oil pump 18 will pump the anti-rust oil inside the oil receiving box 9 into the interior of the mounting plate 17 and spray it out through a number of groups of nozzles fixed on the surface of the mounting plate 17. Thus, the anti-rust oil is sprayed on the surface of the strip 10 through the nozzles. When the strip 10 passes over the top of the second scraping plate 16, the second scraping plate 16 can scrape off the excess anti-rust oil sprayed on the surface of the strip 10 by the nozzles on the surface of the mounting plate 17 and evenly smear the anti-rust oil on the surface of the strip 10. The excess anti-rust oil will fall back into the interior of the oil receiving box 9 through the surface of the second scraping plate 16, thus avoiding the waste of anti-rust oil dripping to the ground and the dirt on the ground. Thus, the anti-rust treatment of the surface of the strip 10 is completed, without moving to a special anti-rust treatment device for anti-rust treatment. The production efficiency is relatively high and the manpower and material resources are relatively saved, and it is relatively convenient to use.
