[0012] Explanation of the numbers in the figure: 100-aluminum belt support roller, 200-oil scraping mechanism, 210-knife holder, 220-rubber scraper, 230-counterweight block, 240-push plate, 300-cylinder, 400-fixing plate, 410-limiting bolt, 420-locking nut. DETAILED DESCRIPTION

[0013] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0014] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0015] like Figure 1~2 As shown, a device for preventing oil from splashing onto the lower surface of the strip includes an aluminum strip support roller 100, and an oil scraping mechanism 200 is provided obliquely below the aluminum strip support roller 100; the oil scraping mechanism 200 includes a knife holder 210 whose middle part is hinged to the oblique lower part of the aluminum strip support roller, and a rubber scraper 220 is connected to the lower surface of the aluminum strip support roller at the first end of the knife holder facing the aluminum strip support roller, and a counterweight 230 is provided on the upper side of the second end of the knife holder away from the aluminum strip support roller. The utility model scrapes off the oil attached to the aluminum strip support roller 100 by arranging the oil scraping mechanism below the aluminum strip support roller 100, thereby preventing the oil from splashing onto the lower surface of the aluminum strip and ensuring the quality of the aluminum material; at the same time, by arranging the counterweight to press down the second end of the knife holder, the rubber scraper 220 at the first end of the knife holder can always be attached to the aluminum strip support roller 100, thereby ensuring the oil scraping effect.

[0016] In this embodiment, the second end of the tool holder is fixedly connected with a push plate 240 on the side of the counterweight away from the aluminum strip support roller, and the push plate is provided with a cylinder 300 on the side away from the aluminum strip support roller for pushing the push plate toward the aluminum strip support roller. After the rubber scraper 220 has been working for a long time, a lot of debris will accumulate on the rubber scraper 220, which needs to be cleaned regularly; when cleaning, the telescopic rod of the cylinder 300 is extended to push the push plate, so that the first end of the tool holder swings down, and the rubber scraper 220 leaves the aluminum strip support roller 100, which is convenient for workers to clean the rubber scraper 220.

[0017] In this embodiment, a fixing plate 400 is provided below the tool holder, and a threaded through hole is provided on the fixing plate, which passes through the upper and lower sides thereof. A limit bolt 410 is passed through the threaded through hole from bottom to top, and a spacing is left between the upper end of the rod of the limit bolt and the lower side of the second end of the tool holder to limit the downward swing angle of the second end of the tool holder. The limit bolt is used to limit the downward swing angle of the second end of the tool holder, thereby controlling the upward swing angle of the first end of the tool holder; as the rubber scraper 220 wears, the first end of the tool holder will get closer and closer to the aluminum strip support roller 100 as it swings upward, and if the first end of the tool holder touches the aluminum strip support roller 100, it will scratch the aluminum strip support roller 100; therefore, the limit bolt 410 is provided to play a protective role, and the downward swing angle of the second end of the tool holder is limited to prevent the first end of the tool holder from touching the aluminum strip support roller 100.

[0018] In this embodiment, the limiting bolt is connected to a locking nut 420 located at the lower side of the fixing plate.

[0019] Unless otherwise stated, any technical solution disclosed in the above utility model, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values ​​to be exhaustive, the utility model discloses only some numerical values ​​to illustrate the technical solution of the utility model, and the numerical values ​​listed above should not constitute a limitation on the scope of protection of the utility model.

[0020] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0021] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0022] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0023] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
