Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Embodiment 1, referring to Figures 1-5 , an automatic cleaning device for the roll system of a continuous annealing unit, including a frame 1 and a roll shaft 4 installed on the frame 1. A support frame is fixed on the frame 1, a pushing support is installed on the support frame, a driving component is installed on the pushing support, a scraper 2 and a counterweight structure are installed on the driving component, and a purging component is installed at one end of the pushing support;

[0025] An arc-shaped notch adapted to the surface of the roll shaft 4 is provided at the cutting edge of the scraper 2;

[0026] The support frame includes two vertical rods 5 fixed on both sides of the frame 1. The tops of the two vertical rods 5 are connected by a cross beam 7, and strip holes 19 are provided at the bottoms of the two vertical rods 5;

[0027] The pushing support includes two electric push rods 6 symmetrically fixed on the lower end surface of the cross beam 7. The bottom ends of the two electric push rods 6 are connected with a U-shaped plate 3;

[0028] The driving component includes a threaded rod 8 rotatably installed between the vertical sections on both sides of the U-shaped plate 3 through bearings. A servo motor 13 is installed at one end of the U-shaped plate 3. The output end of the servo motor 13 is in transmission connection with one end of the threaded rod 8. A T-shaped moving seat 16 is screwed on the threaded rod 8. The upper end of the vertical section of the T-shaped moving seat 16 is in sliding contact with the lower end surface of the horizontal section of the U-shaped plate 3. The two ends of the horizontal section of the T-shaped moving seat 16 are connected to the tool holder of the scraper 2 by bolts;

[0029] The counterweight structure includes support pins 14 welded to both ends of the horizontal section of the T-shaped moving seat 16, and counterweights 15 are sleeved on both support pins 14;

[0030] The purging assembly includes a purging nozzle 9 fixed inside the vertical section at one end of the U-shaped plate 3. An electromagnetic valve 11 is fixed on the upper end face of the U-shaped plate 3. A first hose 12 is connected between one end of the electromagnetic valve 11 and the purging nozzle 9. The other end of the electromagnetic valve 11 is connected to a second hose 10, and one end of the second hose 10 is externally connected to the air outlet end of an air compressor.

[0031] Sliding rods 17 are fixed to the lower ends of the two vertical sections on both sides of the U-shaped plate 3. Fixed rods 18 are fixed in the two strip-shaped holes 19. One end of each of the two sliding rods 17 is slidably sleeved on one of the two fixed rods 18 to increase the stability of the U-shaped plate 3 and prevent the U-shaped plate 3 from shaking.

[0032] Working principle: Use two electric push rods 6 to push the U-shaped plate 3 downward, and then push the scraper 2 downward so that the arc-shaped notch of the scraper 2 is stuck on the surface of the roller 4. Use the servo motor 13 to drive the threaded rod 8 to rotate, and then the threaded rod 8 drives the T-shaped moving seat 16 to drive the scraper 2 to move back and forth on the surface of the roller 4. With the rotation of the roller 4 itself, the scraper 2 can scrape off foreign objects on the surface of the roller 4. During the cleaning stage, regularly open the electromagnetic valve 11 so that the compressed air from the air compressor blows out from the purging nozzle 9, which is convenient for timely blowing the scraped foreign objects out of the unit operation range, effectively avoiding defects such as dents and roller marks on the surface of the strip steel. As the scraper 2 is used, the cutting edge will wear. Counterweight blocks 15 can be sleeved on the two support pins 14 to ensure that the cutting edge of the scraper 2 is in stable contact with the surface of the roller 4, so that the scraper 2 is evenly stressed to ensure that the foreign objects on the surface of the roller 4 are scraped off cleanly.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
