Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil production, in particular to an aluminum foil rolling mill and a rolling oil system thereof. Background Art

[0002] Aluminum foil rolling mill is a mechanical equipment used to make aluminum foil through the rolling process of aluminum plates or strips. It is usually composed of rollers, feeding devices, tension control systems and product collection systems. Aluminum plates or strips pass through a series of rollers to gradually reduce thickness and width and finally form the required aluminum foil. When the rollers are performing normal aluminum foil rolling work, the oil spraying device will spray lubricating oil to the feed side of the rollers to ensure that the lubrication of the aluminum foil during the rolling process meets the requirements. Once the lubrication is lost, rolling hair is likely to occur. In addition, during hot rolling, the lubricating oil can also cool the aluminum foil.

[0003] The traditional oil spraying mechanism uses an oil spray gun to spray the lubricating oil directly onto the roller surface of the rolling mill. However, since there is a lot of waste chips in the atmospheric environment of the production workshop, the roller surface containing the lubricating oil is easily contaminated with certain waste chips when it moves toward the surface of the aluminum foil, which can easily cause defects such as bright lines and pits to appear on the surface of the rolled aluminum foil, thereby affecting the quality of the aluminum foil. In addition, since the roller is long, a large number of oil spray guns are required in the oil spraying mechanism, which leads to a high cost of the oil spraying mechanism, thereby affecting the rolling cost of the aluminum foil. Summary of the invention

[0004] Based on this, it is necessary to provide an aluminum foil rolling mill and its rolling oil system to address the problem that rolling oil affects the rolling quality of aluminum foil during the current aluminum foil rolling process.

The bottoms of the two chambers are communicated, and the oil suction pipe is located in the chamber on the side opposite to the aluminum foil conveying direction.

[0013] Further, a first inclined plate is arranged at the upper end of the partition plate in the first oil injection tank.

The first inclined plate is close to the first oil injection pipe, and the rolling oil sprayed out by the first oil injection pipe enters the chamber on the aluminum foil conveying direction side through the first inclined plate.

[0014] Further, the chamber on the aluminum foil conveying direction side of the second cavity is a special-shaped chamber. The special-shaped chamber is L-shaped, and the two ends of the special-shaped chamber are close to the second rolling roll.

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] The serial numbers assigned to the components in this text, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "coupling" as used in this invention, unless otherwise specifically stated, both include direct and indirect connection (coupling). In the description of this invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this invention.

[0038] In this invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0039] The following refers to Figures 1 - 8 to describe a rolling oil system for an aluminum foil rolling mill provided by this invention.

[0040] A rolling oil system for an aluminum foil rolling mill, which is applicable to the rolling of aluminum foil, includes a frame 100. A rolling roll set is arranged on the frame 100. The rolling roll set is used for rolling aluminum foil. The rolling roll set includes two rolling rolls, which are distributed vertically. There is a gap between the two rolling rolls, and the aluminum foil can enter this gap. When the two rolling rolls rotate, they can roll the aluminum foil to make it thinner. A conveying component (not shown in the figure) is arranged on the frame 100, and the conveying component is used for conveying the aluminum foil. The aluminum foil is continuously conveyed between the two rolling rolls through the conveying component, so that the aluminum foil rolling mill can work continuously. An oil spraying component is arranged on the frame 100, and the oil spraying component can spray rolling oil onto the surface of the rolling rolls. The rolling oil forms an oil film between the rolling rolls and the aluminum foil, effectively reducing the direct contact between the aluminum foil and the rolling rolls, thereby reducing friction. At the same time, it can effectively reduce the heat generated during the processing process and prevent the aluminum foil surface from deforming or being burned due to high temperature.

[0041] In the prior art, rolling oil is generally directly sprayed between two rolling rolls, enabling the aluminum foil at this position to reduce friction and cool during the rolling process. However, there are a large number of waste chips in the atmospheric environment of the production workshop. Therefore, when the rolling roll containing rolling oil moves on the surface of the aluminum foil, it is likely to contaminate a certain amount of waste chips, which easily causes defects such as bright lines and pits on the surface of the rolled aluminum foil, thereby affecting the quality of the aluminum foil. Moreover, the range directly sprayed between the two rolling rolls is small, resulting in an unsatisfactory cooling effect of the rolling roll.

[0042] Therefore, in the present invention, the oil spraying assembly is arranged on one side close to the two rolling rolls. The oil spraying assembly can cyclically spray the rolling oil onto the rolling rolls from the position close to the aluminum foil rolling position to the position gradually away from the rolling position. That is to say, the rolling oil is first sprayed from the position closest to the aluminum foil pressing position, reducing the temperature at this position to the lowest. Subsequently, when the two rolling rolls roll the aluminum foil, the temperature will not be too high. Therefore, spraying the rolling oil at this position first has the best cooling effect. The waste chips washed away by the rolling oil when spraying onto the rolling rolls will be mixed in the rolling oil, thus having a certain cleaning effect on the waste chips on the surface of the rolling rolls. The oil spraying assembly can recover most of the oil liquid, and only a small part of the oil liquid forms an oil film between the aluminum foil and the rolling rolls. During the process of most of the rolling oil flowing back, the waste chips mixed in the rolling oil will be deposited at the bottom of the cavity. Subsequently, the rolling oil is cyclically sprayed at the rolling position far from the aluminum foil. This oil spraying assembly can increase the area where the rolling oil cools the rolling rolls and recycle the rolling oil, reducing the waste of rolling oil.

[0043] Specifically, the oil spraying assembly in this embodiment includes a first oil spraying tank 210 and a second oil spraying tank 310. The first oil spraying tank 210 and the second oil spraying tank 310 are respectively located above and below the rolling rolls and close to the position where the aluminum foil is rolled. As Figure 6 、 Figure 7 and Figure 8 shown. For the convenience of description, the upper rolling roll is named the first rolling roll 200, and the lower rolling roll is named the second rolling roll 300. The upper end surface of the first oil spraying tank 210 is an arc surface to adapt to the first rolling roll 200, and the lower end surface of the second oil spraying tank 310 is also an arc surface to adapt to the second rolling roll 300. The first oil spraying tank 210 includes a plurality of first cavities 220. The plurality of first cavities 220 are arranged along the conveying direction of the aluminum foil (the conveying direction refers to Figure 6A first oil injection pipe 230 is arranged in the first cavity 220, and a plurality of oil injection holes are opened on the first oil injection pipe 230, and the oil injection holes face the first rolling roller 200. The rolling oil in the first oil injection pipe 230 is sprayed toward the first rolling roller 200 through the oil injection holes. A first scraper 250 is arranged on an end face at the front end of each first cavity 220 in the conveying direction of the aluminum foil. A gap is arranged between the first scraper 250 and the first rolling roller 200. The gap size is very small, and a small amount of rolling oil can pass through the gap, so that most of the oil sprayed from the first oil injection pipe 230 will flow back into the first cavity 220, and only a small part of the rolling oil can form an oil film on the surface of the first rolling roller 200 through the gap, which can prevent the thick oil film from affecting the rolling quality of the aluminum foil.

[0044] like Figure 8 As shown, the second spray tank 310 includes a plurality of second cavities 320, and the plurality of second cavities 320 are arranged on the periphery of the second rolling roller 300 along the conveying direction of the aluminum foil (the conveying direction refers to Figure 6 A second oil injection pipe 330 is arranged outside the second cavity 320, and a plurality of oil injection holes are opened on the second oil injection pipe 330, and the oil injection holes face the second rolling roller 300. The rolling oil in the second oil injection pipe 330 is sprayed toward the second rolling roller 300 through the oil injection holes. Each second cavity 320 is provided with a second scraper 350 on an end face on the front side of the aluminum foil conveying direction. A gap is arranged between the second scraper 350 and the second rolling roller 300. The gap size is very small, and a small amount of rolling oil can pass through the gap, so that most of the oil sprayed from the second oil injection pipe 330 will flow back into the second cavity 320, and only a small part of the rolling oil can form an oil film on the surface of the second rolling roller 300 through the gap, which can prevent the thick oil film from affecting the rolling quality of the aluminum foil.

[0045] Specifically, each of the first cavity 220 and the second cavity 320 is provided with an oil extraction pipe 270, and the oil extraction pipe 270 is used to extract the rolling oil in the first cavity 220 or the second cavity 320 and transport it to the first oil injection pipe 230 or the second oil injection pipe 330 near another first cavity 220 or the second cavity 320, specifically, transport it to the first oil injection pipe 230 or the oil injection pipe near the first cavity 220 or the second cavity 320 on the opposite side of the aluminum foil conveying direction, that is, the rolling oil is sprayed out in a circular manner from right to left. For example, taking the first oil injection box 210 as an example, the oil extraction pipe 270 in the first cavity 220 on the far right is connected to the first oil injection pipe 230 in the first cavity 220 on the left adjacent to it, and the connection method between the first oil injection pipe 230 and the oil extraction pipe 270 in the subsequent first cavity 220 is the same as the above connection method. Similarly, the connection method between the second fuel injection pipe 330 and the fuel extraction pipe 270 in the second fuel injection tank 310 will not be described in detail.

[0046] It can be understood that most of the rolling oil ejected from the first oil injection pipe 230 or the second oil injection pipe 330 of the first cavity 220 or the second cavity 320 flows back into the first cavity 220 or the second cavity 320 for sedimentation, and then is pumped away by the oil suction pipe 270 and enters the next first oil injection pipe 230 or the second oil injection pipe 330, circulating in turn, so that the rolling oil can be recycled, and the area where the rolling oil is sprayed onto the rolling rolls as a whole can also be increased.

[0047] In a further embodiment, partitions 260 are provided in both the first cavity 220 and the second cavity 320. The partitions 260 divide the first cavity 220 and the second cavity 320 into two chambers distributed along the aluminum foil conveying direction, that is, as Figure 7 and Figure 8 shown, the partitions 260 divide the first cavity 220 and the second cavity 320 into two chambers distributed left and right. The bottoms of the two chambers are connected, so that the rolling oil flowing back into the first cavity 220 or the second cavity 320 can enter the left chamber from the right chamber. During this process, larger impurities in the rolling oil are deposited at the bottom of the chamber under the action of gravity, and the oil suction pipe 270 is arranged in the chamber on the side opposite to the aluminum foil conveying direction, that is, in the left chamber, specifically at the upper-middle position of the left chamber. When the rolling oil in the left chamber gradually increases, it is pumped away through the oil suction pipe 270, and the rolling oil pumped away through the oil suction pipe 270 enters another first oil injection pipe 230 or second oil injection pipe 330.

[0048] It can be understood that the rolling oil is introduced into the first cavity 220 or the second cavity 320 on the rightmost side. An oil conveyor (not shown in the figure) is connected to the rightmost first oil spray pipe 230 or the second oil spray pipe 330. The oil conveyor transports the rolling oil into the first oil spray pipe 230 or the second oil spray pipe 330. The rolling oil sprays out from the oil spray holes to clean and cool the surfaces of the first rolling roll 200 and the second rolling roll 300. Most of the rolling oil will carry waste chips and flow back into the chamber on the right side. After passing through the communication position at the bottom of the partition 260, it enters the chamber on the left side. Some of the waste chips in the rolling oil are deposited at the bottom of the first cavity 220 or the second cavity 320. As the liquid level of the rolling oil in the left chamber gradually rises, the rolling oil at a higher position in the left chamber contains fewer waste chips. The oil suction pipe 270 inputs this rolling oil into the next first oil spray pipe 230 or the second oil spray pipe 330. Since a large amount of heat is generated during aluminum foil rolling, the position where the oil is sprayed first is set closest to the aluminum foil rolling position, so that the rolling oil can fully cool the first rolling roll 200 and the second rolling roll 300. As the rolling oil circulates, the temperature of the rolling oil gradually rises, and finally it is discharged from the first cavity 220 or the second cavity 320 on the leftmost side. Specifically, it is discharged through the leftmost oil suction pipe 270. The leftmost oil suction pipe 270 is connected to an oil pump (not shown in the figure). The oil pump pumps out the rolling oil, and the pumped rolling oil will enter a cooling system (not shown in the figure) for cooling. At the same time, the cooling system also has a filtering function to remove impurities in the rolling oil. The rolling oil that has been cooled and filtered is re-input into the first cavity 220 or the second cavity 320 on the rightmost side through the oil conveyor, and this cycle continues.

[0049] It can be understood that the cooling system can be any cooling structure in the prior art, such as a cooling pipe. A cold air blower or a compressor is arranged on the outer periphery of the cooling pipe to reduce the temperature of the cooling pipe. The rolling oil pumped out from the leftmost oil suction pipe 270 is introduced into the cooling pipe for cooling. Subsequently, a filtering mechanism such as a filter screen is also arranged inside the cooling pipe to filter the cooled rolling oil. The filtered rolling oil is then introduced back into the first oil spray pipe 230 or the second oil spray pipe 330 on the rightmost side for recycling.

[0050] It should be noted that as Figure 4 and Figure 5 shown, an oil pump 400 is arranged at the end where the first oil spray pipe 230 or the second oil spray pipe 330 and the oil suction pipe 270 communicate with each other outside the first oil spray tank 210 or the second oil spray tank 310. When the oil pump 400 works, it can make the rolling oil in the oil suction pipe 270 enter the first oil spray pipe 230 or the second oil spray pipe 330, and the rolling oil in the first oil spray pipe 230 or the second oil spray pipe 330 sprays out from the oil spray holes under the action of the oil pump 400.

[0051] Specifically, a first inclined plate 240 is provided on the partition plate 260 in the first spraying oil tank 210 of the present invention. Specifically, as Figure 7 shown, the first spraying oil pipe 230 in the first spraying oil tank 210 is located above one end face of the first cavity 220 in the opposite direction of the aluminum foil conveying direction, that is, above the left chamber, and the first inclined plate 240 is inclined towards the direction of the first spraying oil pipe 230, and the oil spraying holes are located above the first inclined plate 240, so that the rolling oil sprayed from the oil spraying holes can enter the right chamber of the first cavity 220 through the diversion of the first inclined plate 240, preventing the rolling oil sprayed from the first spraying oil pipe 230 from being directly sucked away by the lower oil suction pipe 270. If the first inclined plate 240 is not provided, it will cause the rolling oil sprayed from the first spraying oil pipe 230 to carry a large amount of waste chips into the oil suction pipe 270 after hitting the first rolling roll 200, resulting in the failure of the function of depositing waste chips at the bottom of the first cavity 220. By setting the first inclined plate 240, the above situation can be avoided, so that the rolling oil first passes through the right chamber, then through the communication position, and finally enters the left chamber. The liquid level height of the rolling liquid in the left chamber gradually increases. During this process, most of the impurities in the rolling oil can be deposited at the bottom of the first cavity 220 under the action of gravity, so that the content of waste chips in the rolling oil sucked away by the oil suction pipe 270 can be reduced.

[0052] In a further embodiment, the bottom of the first cavity 220 of the first spraying oil tank 210 is detachably provided. When the aluminum foil press completes the aluminum foil rolling operation, the bottom of the first cavity 220 of the first spraying oil tank 210 can be removed. After removal, the waste chips deposited at the bottom can be cleaned and reinstalled, so that there are no waste chips at the bottom of the first cavity 220 during the next operation.

[0053] Specifically, a U-shaped bottom plate 280 is clamped at the bottom of the first cavity 220. The U-shaped bottom plate 280 can be removed from the bottom of the first cavity 220, so as to facilitate the cleaning of the waste chips deposited in the first cavity 220.

[0054] Specifically, the chamber on one side of the second spraying oil tank 310 in the present invention in the aluminum foil conveying direction is a special-shaped chamber. As Figure 8 shown, specifically, it is an L-shaped chamber 360. The two ends of the L-shaped chamber 360 are close to the second rolling roll 300, and the second spraying oil pipe 330 in the second spraying oil tank 310 is located outside the L-shaped chamber 360 and close to the second rolling roll 300. And an oil inlet 370 is provided on the side of the L-shaped chamber 360 close to the aluminum foil conveying direction, that is, the oil inlet 370 is provided on the right side of the L-shaped chamber 360. When the second spraying oil pipe 330 in the second spraying oil tank 310 starts to spray oil, due to the rotation of the second rolling roll 300, and the rotation direction of the second rolling roll 300 is clockwise (taking Figure 8In the clockwise direction when viewed from the front to the back in [reference], the rolling oil sprayed on the surface of the second rolling roll 300 is driven by the second rolling roll 300 to flow upward, so that it can pass through the oil inlet 370 of the L-shaped chamber 360. A second inclined plate 340 is provided at the oil inlet 370 of the L-shaped chamber 360. The second inclined plate 340 is specifically located below the oil inlet 370, and a second scraper 350 is provided above the oil inlet 370. The second inclined plate 340 is tangent to the outer circumference of the rolling roll, so that the rolling oil entering the interior of the L-shaped chamber 360 will not leak out. The rolling oil entering the L-shaped chamber 360 enters the left chamber after passing through the communication position at the bottom of the partition plate 260. The liquid level height of the rolling oil in the left chamber gradually increases, and the oil suction pipe 270 in the left chamber can suck away the rolling liquid with the increasing height, and then transport it to another second oil spray pipe 330, and the second oil spray pipe 330 recycles the rolling oil.

[0055] In a further embodiment, an adjusting assembly is provided on the frame 100. The adjusting assembly can adjust the distance between the first rolling roll 200 and the second rolling roll 300. The adjusting assembly includes two slider groups. Each slider group includes two sliding blocks 110. The two sliding blocks 110 are respectively connected to the two ends of the first rolling roll 200 and the second rolling roll 300, and the first rolling roll 200, the second rolling roll 300 and the two sliding blocks 110 are rotatably connected. The two sliding blocks 110 are slidably connected to the frame 100. When the two sliding blocks 110 slide on the frame 100, they can drive the first rolling roll 200 and the second rolling roll 300 to move away from or close to each other, so as to adjust the distance between the first rolling roll 200 and the second rolling roll 300.

[0056] In a further embodiment, a driving assembly is provided on the frame 100 of the present invention. The driving assembly can drive the first rolling roll 200 and the second rolling roll 300 to rotate around their own axes. As Figure 6 shown, the first rolling roll 200 rotates counterclockwise (counterclockwise when viewed from the front to the back in [reference]), and the second rolling roll 300 rotates clockwise (clockwise when viewed from the front to the back in [reference]). Figure 6 In [reference], the second rolling roll 300 rotates clockwise (clockwise when viewed from the front to the back in [reference]). Figure 6 In [reference], the second rolling roll 300 rotates clockwise (clockwise when viewed from the front to the back in [reference]).

[0057] Specifically, the driving assembly includes a driving motor (not shown in the figure) and a transmission roller set. The transmission roller set includes two pairs of transmission rollers. For the convenience of description, the two pairs of transmission rollers are named the first pair of transmission rollers and the second pair of transmission rollers in sequence from top to bottom. The first pair of transmission rollers includes two first transmission rollers 120, and the second pair of transmission rollers includes two second transmission rollers 130. The two first transmission rollers 120 and the second transmission rollers 130 are symmetrically arranged, and the diameter of the first transmission rollers 120 is larger than that of the second transmission rollers 130. The driving motor is fixedly arranged on the frame 100. The outer periphery of the first transmission rollers 120 is in rolling contact with the outer periphery of the second transmission rollers 130 and the rotating shaft of the driving motor at the same time, so that when the driving motor rotates, it can drive the first transmission rollers 120 to rotate, and the first transmission rollers 120 drive the second transmission rollers 130 to rotate. The two second transmission rollers 130 are in rolling contact with the first rolling roller 200 and the second transmission rollers 130 at the same time, so that the second transmission rollers 130 drive the first rolling roller 200 and the second rolling roller 300 to rotate.

[0058] It can be understood that setting multiple pairs of transmission rollers can improve the transmission accuracy, so that the rolling rollers rotate more precisely and the quality of aluminum foil rolling is improved.

[0059] Combined with the above embodiments, the specific working process of a rolling oil system of an aluminum foil rolling mill provided by the present invention will be described:

[0060] Start the oil conveyor (not shown in the figure), the oil pump 400 and the oil extractor (not shown in the figure). The oil conveyor conveys the rolling oil into the first spray oil tank 210 and the second spray oil tank 310. The working state of the rolling oil in the first spray oil tank 210 is as follows:

[0061] The rolling oil first passes through the first cavity 220 on the far right. The rolling oil is ejected from the first oil spray pipe 230 of the first cavity 220 on the far right. The rolling oil is sprayed onto the first rolling roll 200. The rolling oil mixes the waste chips on the surface of the first rolling roll 200 and drives the pressing oil to move towards the first scraping plate 250 on the first cavity 220 under the action of the rotation of the first rolling roll 200. Since there is a very small gap between the first scraping plate 250 and the first rolling roll 200, the first scraping plate 250 can scrape most of the rolling oil, so that most of the rolling oil flows back into the first cavity 220. Only a small part of the rolling oil passes through the first scraping plate 250, so that there is only a thin oil film on the surface of the first rolling roll 200, thereby improving the rolling quality of the aluminum foil. The rolling oil flowing back into the first cavity 220 flows to the right side of the partition plate 260, that is, the chamber on the right side in the first cavity 220. The rolling oil enters the chamber on the left side through the communication position below the partition plate 260. As the amount of sprayed oil increases, the liquid level height of the rolling oil in the left chamber increases. During the process of the increase of the liquid level height of the rolling oil, the waste chips in the rolling oil can gradually settle at the bottom of the first cavity 220 under the action of gravity. When the liquid level height gradually approaches the oil suction pipe 270, due to the action of the oil pump 400, the oil suction pipe 270 can extract the rolling oil exceeding the oil suction pipe 270. The extracted rolling oil enters the first oil spray pipe 230 in another first cavity 220 through the oil pump 400. The flow state of the rolling oil in the first oil spray pipe 230 is the same as that of the rolling oil in the first cavity 220 on the far right, and will not be elaborated here. The rolling oil continuously flows from right to left. An oil extractor is connected to the oil suction pipe 270 in the leftmost cavity. The oil extractor extracts the rolling oil. The extracted rolling oil is re-output by the oil transporter after cooling and temperature reduction. The rolling oil re-enters the first oil spray pipe 230 in the first cavity 220 on the far right, and circulates in this way.

[0062] The working state of the rolling oil in the second oil spray tank 310 is as follows:

[0063] As Figure 8 shown, the oil spray pipe in the second oil spray tank 310 is located at the lower left of the L-shaped chamber 360. After the oil transporter transports the rolling oil into the second oil spray pipe 330, the rolling oil is ejected from the second oil spray pipe 330. The rolling oil is sprayed onto the second rolling roll 300. Due to the rotation of the second rolling roll 300, specifically clockwise (in Figure 8In the clockwise direction when looking from front to back (in the figure), the second rolling roll 300 drives the rolling oil to move synchronously. When the rolling oil moves to the oil inlet 370 on the right side of the L-shaped chamber 360, the second scraper 350 at the position of the oil inlet 370 scrapes most of the rolling oil into the L-shaped chamber 360. The second inclined plate 340 at the oil inlet 370 prevents the rolling oil from separating from the L-shaped chamber 360. The rolling oil passes through the bottom of the partition plate 260 in the second cavity 320, and the liquid level height of the rolling oil in the left chamber gradually increases. The waste chips mixed in the rolling oil are deposited at the bottom of the second cavity 320 under the action of gravity. The oil suction pipe 270 in the left chamber extracts the rolling oil, and the rolling oil is transported into the second spray pipe 330 connected thereto through the oil pump 400. The rolling oil is ejected from the spray holes under the action of the oil pump 400. The flow state of the rolling oil in the second cavity 320 is the same as that of the rolling oil in the rightmost L-shaped chamber 360, and will not be elaborated here. The rolling oil flows continuously from right to left. An oil extractor is connected to the oil suction pipe 270 in the leftmost second cavity 320. The oil extractor extracts the rolling oil, and the extracted rolling oil is re-output by the oil transporter after cooling and temperature reduction. The rolling oil re-enters the spray pipe in the rightmost chamber, and circulates in this way.

[0064] The present invention also provides an aluminum foil rolling mill, which includes the above-mentioned rolling oil system and a conveying component. The conveying component is used to convey aluminum foil. Specifically, the conveying component includes conveying rolls (not shown in the figure). A large number of aluminum foils are wound around the outer circumference of the conveying rolls. The rotation of the conveying rolls can unwind the aluminum foil. When the two rolling rolls roll the aluminum foil, they can pull the aluminum foil to unwind the aluminum foil on the outer circumference of the conveying rolls.

[0065] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered to be within the scope described in this specification.

[0066] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
