[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4, A metal rolling mill with adjustable rolling rolls, including support side plates 1. Inside the support side plates 1, there are parallel upper rolling roll 2 and lower rolling roll 3. The upper rolling roll 2 is installed inside the support side plates 1 through bearings, and at the connection of the lower rolling roll 3 and the support side plates 1, there is a rolling roll adjustment component 4 for adjusting the height of the lower rolling roll 3. On the surfaces of the upper rolling roll 2 and the lower rolling roll 3, there is a cleaning component 5. At the bottom of the support side plates 1, there is a support bottom plate 6 fixed by welding.

[0028] The cleaning component 5 includes a cleaning bracket 501. Inside the cleaning bracket 501, there is an upper cleaning ring 502, and below the upper cleaning ring 502, there is a moving slider 510. Inside the moving slider 510, there is a lower cleaning ring 507. The upper cleaning ring 502 and the lower cleaning ring 507 are respectively sleeved on the surfaces of the upper rolling roll 2 and the lower rolling roll 3. At the connection of the moving slider 510 and the cleaning bracket 501, there is a cleaning chute 504. At the connection of the cleaning chute 504 and the moving slider 510, there is an engaging slider 509, and between the cleaning chute 504 and the moving slider 510, there is an engaging spring 508.

[0029] The engaging spring 508 is fixed on the upper and lower sides of the moving slider 510. The cleaning chute 504 is elastically connected to the moving slider 510 through the engaging spring 508.

[0030] By adopting the above technical solution, since the lower rolling roll 3 passes through the inside of the lower cleaning ring 507, when the height of the lower rolling roll 3 is adjusted, the lower rolling roll 3 can drive the moving slider 510 on the lower cleaning ring 507 to slide in the cleaning chute 504, and make the engaging spring 508 expand and contract, automatically adjusting in cooperation with the height of the lower rolling roll 3, without manually adjusting the height of the lower cleaning ring 507.

[0031] Specifically, as Figure 4 shown, the cleaning component 5 further includes a moving lead screw 503 passing through the inside of the cleaning bracket 501. The moving lead screw 503 is connected to the cleaning bracket 501 through a lead screw sleeve. The moving lead screw 503 is located above the upper cleaning ring 502. At the bottom of the cleaning bracket 501, there is a limiting slider 505, and outside the limiting slider 505, there is a limiting chute 506. The limiting chute 506 is opened on the top surface of the support bottom plate 6.

[0032] The calender roll adjusting assembly 4 includes an adjusting motor 403 installed on the support side plate 1 by bolts. The output end of the adjusting motor 403 is connected with a worm 404, and a worm gear 405 is meshed and connected to one side of the worm 404. An adjusting screw rod 406 is fixedly arranged below the worm gear 405, and a screw rod sleeve 407 is installed outside the adjusting screw rod 406. A support slider 402 is fixedly arranged outside the screw rod sleeve 407. A guiding chute 401 is provided at the connection between the support slider 402 and the support side plate 1. The lower calender roll 3 is installed on the support slider 402 through bearings.

[0033] By adopting the above technical solution, after starting the adjusting motor 403, the adjusting motor 403 drives the worm 404 to rotate, and the worm 404 synchronously drives the worm gear 405 to rotate. After the worm gear 405 drives the adjusting screw rod 406 to rotate, the screw rod sleeve 407 can drive the support slider 402 to move up and down in the guiding chute 401, thereby driving the lower calender roll 3 to adjust its height. The worm gear 405 and the worm 404 have a self-locking function. One side of the upper calender roll 2 is connected with a driving motor. At this time, the metal can pass through between the upper calender roll 2 and the lower calender roll 3. As the upper calender roll 2 rotates, the metal is calendered. When it is necessary to clean the upper calender roll 2 and the lower calender roll 3, the screw rod motor connected to the moving screw rod 503 can be controlled to drive the moving screw rod 503 to rotate, so that the limit slider 505 on the cleaning bracket 501 slides inside the limit chute 506, thereby cleaning the upper calender roll 2 and the lower calender roll 3.

[0034] Working principle: Adjust the distance between the upper calender roll 2 and the lower calender roll 3 according to the thickness of the metal. Start the adjusting motor 403, drive the worm 404 to rotate, and then drive the adjusting screw rod 406 to rotate through the worm gear 405. At this time, the screw rod sleeve 407 drives the support slider 402 to move up and down in the guiding chute 401 to adjust the height of the lower calender roll 3. At the same time, the lower calender roll 3 can drive the moving slider 510 on the lower cleaning ring 507 to slide in the cleaning chute 504, and make the connecting spring 508 expand and contract, and automatically adjust in cooperation with the height of the lower calender roll 3. The metal can pass through between the upper calender roll 2 and the lower calender roll 3. As the upper calender roll 2 rotates, the metal is calendered. When it is necessary to clean the upper calender roll 2 and the lower calender roll 3, the screw rod motor drives the moving screw rod 503 to rotate, so that the limit slider 505 on the cleaning bracket 501 slides inside the limit chute 506, thereby cleaning the upper calender roll 2 and the lower calender roll 3.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
