[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Referring to Figures 1-5 , a surface treatment device for a steel strip according to the present invention includes a cleaning frame 1, a cleaning tank 2, a first cleaning component, a second cleaning component, and a drying device. The cleaning tank 2 is located at the lower left of the cleaning frame 1. The first cleaning component and the second cleaning component are located on the cleaning frame 1 and are rotationally symmetric. The drying device is located at the upper right of the cleaning frame 1. After passing through the previous process, the steel strip enters the cleaning tank 2 and is successively cleaned through between the first cleaning component and the second cleaning component and the drying device. The first cleaning component includes a cleaning scraper 11 installed on the cleaning frame 1 and a sliding groove 12 arranged on the inner side of the cleaning frame 1. The sliding groove 12 is an irregular-shaped return groove and is flush with the direction of the steel strip transmission on the side close to the steel strip. A movement structure for driving the cleaning scraper 11 to reciprocate and clean the steel strip is arranged on the cleaning frame 1. A nozzle 111 is arranged on the left side surface of the cleaning scraper 11 facing the steel strip. The nozzle 111 is used for water-washing the impurities accumulated on the cleaning scraper 11. A control structure for controlling the opening and closing of the nozzle 111 is arranged on the sliding groove 12;

[0028] In the initial state, the cleaning scraper 11 is located above the cleaning frame 1, and the lower side of the cleaning scraper 11 is in contact with and abuts against the upper surface of the steel strip. During the transmission of the steel strip, the movement structure drives the cleaning scraper 11 to move downward to scrape off the adhesives on the surface of the steel strip. When the cleaning scraper 11 moves to the lowest position of the sliding groove 12, the control structure controls the nozzle 111 to spray water on the upper surface of the steel strip to wash away the adhesives scraped off from the surface of the steel strip. At the same time, the cleaning scraper 11 quickly returns to the initial state under the action of the movement structure. When the cleaning scraper 11 moves to the initial position, the nozzle 111 sprays water and the cleaning scraper 11 starts to move downward again to scrape off the adhesives on the surface of the steel strip. The cleaned steel strip continues to move and is dried by the drying device and then enters the lower process for processing. It should be noted that the first cleaning component and the second cleaning component are arranged oppositely on the cleaning frame 1, and the cleaning scrapers 11 on the first cleaning component and the second cleaning component tightly abut against both sides of the steel strip. The transmission speed of the steel strip is less than the movement speed of the cleaning scraper 11. The cleaning scrapers 11 arranged on both sides of the steel strip slide in the sliding groove 12 to effectively clean the impurities remaining from the previous process on both sides of the steel strip, and at the same time, the nozzle 111 sprays clear water to effectively clean the impurities, improving the cleanliness of both sides of the steel strip and effectively avoiding rust caused by residual impurities on the steel strip.

[0029] The connection part of the sliding groove 12 that is flush with the steel strip transmission direction is a smoothly transitioned arc, and the upper part of the sliding groove 12 is connected by an arc. The square-ber sliding shaft 112 slides continuously and unidirectionally in the sliding groove 12.

[0030] The first cleaning component further includes a sliding shaft 112 disposed on the cleaning blade 11. The sliding shaft 112 slides within the sliding groove 12, and the motion structure is fixedly connected to the portion of the sliding shaft 112 outside the sliding groove 12. The motion structure includes a driving motor 13 installed on the outer side of the cleaning frame 1. A driving gear 131 is installed on the output shaft of the driving motor 13. The driving gear 131 is located inside the cleaning frame 1. A driving frame 113 is fixedly installed on the sliding shaft 112. A driving rack 114 is disposed on the driving frame 113. The driving rack 114 is meshed and connected with the driving gear 131. When the driving motor 13 rotates, it drives the driving rack 114 to move. The driving rack 114 drives the sliding shaft 112 to move downward. The sliding shaft 112 drives the cleaning blade 11 to clean the surface of the steel strip. When the cleaning blade 11 moves to the lowest position, the motion structure drives the cleaning blade 11 to move to the initial position along the direction of the sliding groove 12. During this process, the cleaning blade 11 is separated from and no longer in contact with the surface of the steel strip.

[0031] The motion structure further includes a rotating seat 14 rotatably installed on the cleaning frame 1. An elastic telescopic rod 141 is fixedly installed on the rotating seat 14. A spring is disposed inside the elastic telescopic rod 141. The other end of the elastic telescopic rod 141 is fixedly connected to the sliding shaft 112. The spring is always in a stretched state. When the cleaning blade 11 moves to the lowest position, the elastic telescopic rod 141 moves to its longest length, and the pulling force of the spring is the greatest. At this time, the elastic telescopic rod 141 is pulled back to its shortest state. Through the reciprocating action of the elastic telescopic rod 141, the driving rack 114, and the driving gear 131, the continuous cleaning of the surface of the steel strip is ensured, and the cleanliness of the steel strip is improved.

[0032] The control structure includes an upper switch 15 and a lower switch 16 disposed at the upper end of the sliding groove 12 at a position flush with the moving direction of the steel strip. When the cleaning blade 11 moves to the initial position on the sliding groove 12, the upper switch 15 controls the nozzle 111 to stop spraying water. When the cleaning blade 11 moves to the lowest position on the sliding groove 12, the lower switch 16 controls the nozzle 111 to start spraying water. Thus, it is ensured that the nozzle 111 starts spraying water after the cleaning blade 11 is separated from the steel strip, so that the scraped adhesions can be washed away in time. When the cleaning blade 11 comes into contact with the steel strip, the nozzle 111 stops spraying water, thereby effectively saving water.

[0033] The drying device is a sponge drying rod 17 installed on the cleaning frame 1. The sponge drying rod 17 is located on both sides of the steel strip and is in contact with both sides of the steel strip, thereby ensuring the water removal effect on the surface of the steel strip.

[0034] A water tank 18 is installed on the outer side of the cleaning frame 1. The water tank 18 is connected to the nozzle 111 through a water pipe to provide water for the cleaning of the nozzle 111.

[0035] In the present utility model, during the transmission of the steel strip, the movement structure drives the cleaning scraper 11 to move downward to scrape off the adhesions on the surface of the steel strip; when the cleaning scraper 11 moves to the lowest position of the sliding groove 12, the control structure controls the nozzle 111 to spray water on the upper surface of the steel strip to wash away the adhesions scraped off from the surface of the steel strip. At the same time, the cleaning scraper 11 quickly returns to the initial state under the action of the movement structure. When the cleaning scraper 11 moves to the initial position, the nozzle 111 sprays water and the cleaning scraper 11 starts to move downward again to scrape off the adhesions on the surface of the steel strip. The cleaned steel strip continues to move, passes through the drying device for drying, and then enters the lower process for processing. The cleaning scrapers 11 provided on both sides of the steel strip slide in the sliding groove 12 to effectively clean the impurities remaining from the previous process on both sides of the steel strip. At the same time, clear water is sprayed through the nozzle 111 to effectively wash the impurities, improving the cleanliness of both sides of the steel strip and effectively preventing rust caused by impurities remaining on the steel strip.
