[0023] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] See also Figure 1-5 , Embodiment 1 provides an oil cleaning structure of an aluminum foil rolling mill, including an upper cleaning roller 3, a lower cleaning roller 4, a lower edge cleaning mechanism 5, and an upper edge cleaning mechanism 6. The upper cleaning roller 3 and the lower cleaning roller 4 are respectively located at the front and rear sides of the corresponding support roller 1; specifically, the lower cleaning roller 4 is located at the middle of the rear side of the lower support roller 1 (the top rotates forward), and the upper cleaning roller 3 is located at the middle of the front side of the upper support roller 1 (the bottom rotates forward). In the aluminum foil rolling mill (very precise), a large number of other structures are set up, resulting in a very compact structure; the applicant found that: there is installation space at the upper rear side upper part of the upper support roller 1 and the upper rear side upper part of the lower support roller 1, then the upper edge cleaning mechanism 6 and the lower edge cleaning mechanism 5 are respectively located at the upper rear side upper part of the upper support roller 1 and the upper rear side upper part of the lower support roller 1, and the upper edge cleaning mechanism 6 and the lower edge cleaning mechanism 5 are used to clean (including scraping and sucking) the two ends of the two support rollers 1 respectively.

[0026] Specifically, the lower edge cleaning mechanism 5 and the upper edge cleaning mechanism 6 each include two edge cleaning units, which are respectively located at the left and right ends of the support roller 1. The edge cleaning unit includes an arc-shaped pressing plate 7, a felt sheet 8, and a plurality of locking bolts 9. The arc-shaped pressing plate 7 is an arc-shaped plate that cooperates with the support roller 1, and its outer end is fixed to the bearing box 10 (specifically a circular boss 11) at the corresponding end (left end or right end) through a locking bolt 9. It is coaxially arranged with the support roller 1, located at the upper rear side of the support roller 1, and arranged in the left and right directions. Its inner diameter is slightly larger than the diameter of the support roller 1, and is slightly smaller than the felt sheet 8. The felt sheet 8 is located between the arc-shaped pressing plate 7 and the support roller 1, and is tightly pressed on the circumference of the corresponding end of the support roller 1. It shields the gap between the support roller 1 and the bearing box 10, and its outer end (the outer end of the felt sheet 8 is provided with a through hole for the locking bolt 9 to pass through) is fixed to the locking bolt 9.

[0027] In this patent, the two support rollers 1 need to be replaced after being used for a period of time (such as 20 minutes) to ensure accuracy. When replacing the support rollers 1, the felt sheet 8 can be replaced (loosen the nut on the locking bolt 9) to ensure the cleanliness and oil absorption capacity of the felt sheet 8.

[0028] Furthermore, a circular boss 11 (which is an existing structure) is provided on the inner side of the bearing box 10 in the embodiment of the utility model along the left-right direction. The support roller 1 is arranged along the left-right direction, and is located between the two bearing boxes 10, and its left and right ends are respectively arranged on the circular bosses 11 of the two bearing boxes 10. The upper support roller 1 is located on the upper side of the upper rolling roller 2, and the lower support roller 1 is located on the lower side of the lower rolling roller 2. The circular boss 11 is coaxially arranged with the support roller 1, and its circumferential surface is basically flush with the circumferential surface of the support roller 1. It is located on the adjacent outer side of the corresponding end of the support roller 1, and a bearing is provided therein, and there is a gap between it and the support roller 1. The outer end of the arc pressure plate 7 is fixed to the circumferential surface of the circular boss 11 by a locking bolt 9. Then the outer end of the felt sheet 8 is clamped between the outer end of the arc pressure plate 7 and the circular boss 11.

[0029] Specifically, the number of the locking bolts 9 in the embodiment of the utility model is two, and the two locking bolts 9 are arranged side by side in the circumferential direction of the circular boss 11; accordingly, two through holes are provided at the outer end of the felt sheet 8. Specifically, the locking bolts 9 are arranged along the radial direction of the circular boss 11, and the lower end thereof is fixed on the circumferential surface of the circular boss 11, and a locking nut (located on the upper side of the arc-shaped pressing plate 7) is provided thereon. The felt sheet 8 can be replaced by loosening the locking nut.

[0030] Preferably, the upper side edge, lower side edge and inner side edge of the felt sheet 8 in the embodiment of the utility model extend upward, downward and inward respectively relative to the corresponding edges of the arc pressure plate 7 to avoid scratching the support roller 1, avoid oil entering between the arc pressure plate 7 and the support roller 1 and ensure the oil absorption capacity; the outer side edge of the felt sheet 8 can be flush with the outer side edge of the arc pressure plate 7.

[0031] The felt sheet 8 in the embodiment of the utility model is a rectangular sheet, and the arc-shaped pressing plate 7 is an arc-shaped rectangular metal plate. The thickness of the felt sheet 8 is 8-15 mm, the length is 250-400 mm, the width is 250-400 mm, and the length extending from the corresponding side of the arc-shaped pressing plate 7 is 20-40 mm (not too long, otherwise it will easily warp and form a gap).
