Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate rolling, and more specifically, to an oil baffle device for aluminum plate rolling. Background Art

[0002] After aluminum plates are rolled, defects such as "black oil spots and yellow oil spots" often appear, resulting in poor surface quality of the products. Analyzing the reasons, it is caused by oil droplets on the aluminum foil during the rolling process.

[0003] In the prior art, the publication number is: CN209238707U, an oil baffle device for aluminum foil rolling, aiming to solve the technical problem that oil is easily splashed onto the rolled aluminum foil. The device includes a baffle I in a shape of ︹ covering the outside of the support roll I, a baffle II in a shape of ︺ covering the outside of the support roll II, and rotating rolls arranged on the upper and lower sides of the aluminum foil strip. An oil-absorbing cotton layer is provided on the rotating rolls. On the oil-splashing side of the support roll, anti-splashing oil plates are provided on both sides of the bottom end of the baffle I and both sides of the top end of the baffle II, and a row of oil guiding ribs distributed in a Λ shape is provided on the inner side of the baffle I. In the utility model, the baffle can block the splashed oil and let it flow away along the oil guiding ribs, and can also block and collect the liquefied oil droplets. At the same time, the residual oil on the aluminum foil is completely absorbed by the oil-absorbing cotton layer; the anti-splashing oil plate can effectively block the oil splashed from the roll neck and prevent the splashed oil from dripping onto the aluminum foil.

[0004] However, the above patent still has certain disadvantages in use: the structure of the oil baffle device used in the aluminum plate rolling process is relatively complex, and it is inconvenient to install and maintain, which is not conducive to rapid use. Moreover, its shielding and protection of various rolls are not very comprehensive, there are certain gaps and unshielded areas, and the oil that has not been completely removed still has a space to splash, resulting in an unsatisfactory actual oil baffle effect.

[0005] For the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the utility model, an oil blocking device for rolling aluminum plates is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figures 1-4 As shown, the oil blocking device for aluminum plate rolling according to the embodiment of the utility model comprises a rolling mill roller 1 and a threaded hole 7, an upper protective cover 2 and a lower protective cover 13 are respectively sleeved on the outer peripheral surface of the rolling mill roller 1, an outer scraper ring 10 is surrounded by one end surface of the upper protective cover 2 and the lower protective cover 13, a plurality of groups of oil leakage grooves 14 are opened on the surface of the outer scraper ring 10, one end of the outer scraper ring 10 is located at the inner surface of the upper protective cover 2 and the lower protective cover 13 and is evenly surrounded by a plurality of groups of inner scraper rings 4, and the inner scraper rings 4 are located between two of them. An oil-absorbing cotton layer 3 is provided on the inner wall surface of the upper protective cover 2 and the lower protective cover 13, and an oil suction port 5 is provided in the middle position of the surface of one side of the inner scraper ring 4. One end of the oil suction port 5 passes through the surface of the upper protective cover 2 and the lower protective cover 13 and is connected to the guide pipe 9. The other end of the guide pipe 9 is connected to a pump 8, and the other end of the pump 8 is connected to an external collection box. The pump 8 is a common pump body that can absorb and transmit liquid. The specific type can be adjusted according to personnel needs, such as an oil pump, which can be installed on the surface of the rolling mill.

[0031] In one embodiment, connecting rods 11 are symmetrically installed on both sides of the bottom end of the upper protective cover 2 at both ends of the surface of the outer scraper ring 10, and an oil collecting cylinder 12 is fixedly installed on the bottom surface of the connecting rod 11.

[0032] In one embodiment, a mounting seat 6 is fixedly installed in the middle position of one end surface of the upper protective cover 2 and the lower protective cover 13, and threaded holes 7 are symmetrically provided on the surface of the mounting seat 6. The upper protective cover 2 and the lower protective cover 13 can be installed at corresponding positions of the rolling mill roller 1 at different positions through the mounting seat 6, so as to facilitate subsequent oil blocking operations.

[0033] In one embodiment, the oil collecting cylinder 12 is located directly below the oil leakage groove 14 , and the oil leaking from the oil leakage groove 14 can be collected and processed through the oil collecting cylinder 12 .

[0034] In one embodiment, the upper protective cover 2 and the lower protective cover 13 are both made of metal material, and the metal material ensures the strength of both.

[0035] In one embodiment, arc-shaped grooves are provided on the surfaces of the inner scraping ring 4 and the outer scraping ring 10, and the arc dimensions are the same as the radian of the rolling mill roller 1. The same radian ensures that the above two can fit on the surface of the rolling mill roller 1, facilitating more thorough scraping of the oil on its surface.

[0036] In one embodiment, rubber layers are wrapped on the surfaces of the inner scraping ring 4 and the outer scraping ring 10. The rubber layers are provided to reduce the friction between the two and the rolling mill roller 1 and avoid direct contact between metal structures, which may cause scratches.

[0037] In one embodiment, the oil collecting cylinder 12 is installed obliquely. The oblique setting is to ensure that there is a certain inclination angle between the oil collecting cylinder 12 and the outer scraping ring 10, so that the front end of the oil collecting cylinder 12 is slightly longer than the front end of the outer scraping ring 10, ensuring that all the oil discharged from the oil leakage groove 14 falls into the interior of the oil collecting cylinder 12 and preventing external leakage from contaminating the aluminum plate.

[0038] Working principle: During actual use, the corresponding upper protective cover 2 and lower protective cover 13 can be sleeved on the outer periphery of the rolling mill roller 1 inside the corresponding rolling mill to perform the oil blocking operation. Then, the above two can be installed on the surface of the rolling mill through the threaded holes 7 and bolts on the surface of the mounting seat 6 to achieve fixation. Then, when the rolling mill roller 1 drives the aluminum plate to be rolled and moves, the outer scraping ring 10 and the inner scraping ring 4 on the surfaces of the upper protective cover 2 and the lower protective cover 13 can perform multiple scraping operations on the surface of the rolling mill roller 1, thereby improving the removal effect of the cooling oil on its surface. Some of the cooling oil that is not completely removed will splash into the sealed space formed by the upper protective cover 2 and the lower protective cover 13 during its high-speed rotation. Part of the cooling oil that splashes to the innermost end will be adsorbed by the oil-absorbing cotton in the oil-absorbing cotton layer 3, and the other part will be pumped out through the oil suction port 5 to achieve the removal of the splashed cooling oil. The overall use of the upper protective cover 2 and the lower protective cover 13 to perform oil blocking treatment on the rolling mill roller 1 at different installation positions has the advantages of simple structure, easy installation, and the formed sealed space can effectively prevent the incompletely scraped oil from splashing out and contaminating the aluminum plate, ensuring the production effect of the aluminum plate. The device as a whole has the advantages of simple structure, good oil blocking effect, and comprehensive protection.
