[0026] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., according to actual needs.

[0027] In order to solve the problem that when the blowing device of the cold rolling mill is in use, it is very easy for the scraper to be in poor contact with the aluminum strip, reducing the cleaning effect of the cold rolling oil adhered to the aluminum strip, please refer to Figures 1 to 5 The structure of the device body is a bottom plate 1 with a groove on the top surface, a U-shaped inverted support plate 3 and a fixing plate 4. The bottom plate 1 provides a supporting function, and at the same time, it is convenient to collect the cleaned cold rolling oil through the groove on the top surface of the bottom plate 1. During the cold rolling process of the aluminum strip, cold rolling oil is usually used to provide cooling and lubrication functions. The bottom surfaces of the two columns of the support plate 3 and the fixing plate 4 are both welded to the bottom plate 1 to fix the positions of the support plate 3 and the fixing plate 4. An electric telescopic rod 5 is fixedly connected to the inner top wall of the support plate 3. The support plate 3 provides a fixing function for the position of the electric telescopic rod 5. A moving plate 6 is welded to the moving end of the electric telescopic rod 5, which is convenient for the moving end of the electric telescopic rod 5 to drive the moving plate 6 to move longitudinally during the movement. Both ends of the top of the moving plate 6 are inserted with sliding rods 7 through the through grooves opened.

[0028] The two set sliding rods 7 further fix the moving path of the moving plate 6. A connecting plate 8 is sleeved on the side of the sliding rod 7. The top surface of the connecting plate 8 is inserted with the sliding rod 7 through the through groove opened, which is convenient for the connecting plate 8 to move longitudinally along the path of the sliding rod 7. An active plate 10 is fixedly connected to the adjacent side of the two connecting plates 8. The two set connecting plates 8 provide a connecting function to realize the synchronous movement of the two connecting plates 8 and an active plate 10. A rubber plate 11 is fixedly connected to the bottom surface of the active plate 10. The active plate 10 provides a supporting function for the rubber plate 11 to prevent the rubber plate 11 from being bent. The bottom surface of the rubber plate 11 abuts against the conveyor belt of the conveyor 2. The fixed end of the conveyor 2 is installed on the top surface of the bottom plate 1. A pressure-increasing spring 9 is sleeved on the side of the sliding rod 7. Both end faces of the pressure-increasing spring 9 are welded to the moving plate 6 and the connecting plate 8 respectively.

[0029] The set pressure-increasing spring 9 provides an elastic acting force. Powered by the electric telescopic rod 5, the moving plate 6 moves upward. Under the elastic pulling force provided by the pressure-increasing spring 9, the abutting action between the bottom surface of the rubber plate 11 and the conveyor belt of the conveyor 2 is released, so that the conveyor 2 provides a conveying function for the aluminum strip. Under the downward movement of the moving end of the electric telescopic rod 5, the bottom surface of the rubber plate 11 abuts against the aluminum strip, realizing the scraping effect on the cold rolling oil of the cold rolling mill adhered to the aluminum strip, and at the same time, it is convenient to improve the abutting tightness between the bottom surface of the rubber plate 11 and the aluminum strip, improving the cleaning effect. The set pressure-increasing spring 9 provides an elastic thrust and at the same time provides a buffering and protection function to prevent the force of the electric telescopic rod 5 from being inconvenient to control and causing damage to the aluminum strip.

[0030] The two inner side walls of the support plate 3 are fixedly connected to the sliding rods 7 through the through grooves provided, so as to fix the positions of the two sliding rods 7. A rotary motor 12 is installed on the top surface of the fixed plate 4. The fixed end of the rotary motor 12 is detachably connected to the top surface of the fixed plate 4 through bolts, so as to fix the position of the rotary motor 12. A rotary rod 13 is welded to the output shaft of the rotary motor 12, which is convenient for driving the rotary rod 13 to rotate synchronously during the rotation of the output shaft of the rotary motor 12. A rotary plate 14 is fixedly connected to the bottom surface of the rotary rod 13. An active block 15 is fixedly connected to the bottom surface of the rotary plate 14. The rotary rod 13 and the active block 15 fixedly connected to the top and bottom surfaces of the rotary plate 14 are arranged in a staggered manner, which is convenient for the active block 15 to perform circular movement with the rotary rod 13 as the center. The side surface of the active block 15 is movably connected to an active frame 16, so that the active block 15 rotates and moves relatively along the inner side wall of the active frame 16.

[0031] The bottom surface of the active frame 16 is fixedly connected to a hollow mounting plate 17, so as to realize the synchronous movement of the active frame 16 and the mounting plate 17. A plurality of nozzles are communicated with the side surface of the mounting plate 17. Active rods 18 are welded to both end surfaces of the mounting plate 17. The two inner side walls of the fixed plate 4 are slidably connected to the active rods 18 through the through grooves provided, so as to fix the movement path of the active rods 18. During the transmission process, the transverse reciprocating movement of the mounting plate 17 is realized, which is convenient for increasing the spraying range of a plurality of nozzles and improving the cleaning effect on the cold rolling oil of the cold rolling mill adhered to the surface of the aluminum strip. At the same time, it is convenient for the sprayed gas to push the cold rolling oil adhered to the surface of the aluminum strip to flow out from the edge of the aluminum strip and fall into the groove on the top surface of the bottom plate 1 for collection. The reserved length of the provided active rods 18 is sufficient to prevent the active rods 18 from detaching from the fixed plate 4 during the movement process, and improve the structural stability of the device components. A conduit 19 is communicated with the top surface of the mounting plate 17. An air pump 20 is communicated with the outer peripheral side of the conduit 19. The provided air pump 20 extracts external air and introduces the air into the inner cavity of the mounting plate 17 through the conduit 19, and then sprays it out through a plurality of nozzles, so as to realize the cleaning effect on the cold rolling oil of the cold rolling mill adhered to the surface of the aluminum strip. The fixed end of the air pump 20 is installed on the top surface of the fixed plate 4, and the fixed end of the air pump 20 is detachably connected to the top surface of the fixed plate 4 through bolts.
