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

[0022] Refer to the following Figure 1-Figure 8 To describe a rolling oil system for an aluminum foil rolling mill provided by the present invention.

[0023] A rolling oil system for an aluminum foil rolling mill is suitable for rolling aluminum foil, comprising a frame 100. A rolling roller group is arranged on the frame 100. The rolling roller group is used for rolling aluminum foil. The rolling roller group comprises two rolling rollers, which are distributed up and down. There is a gap between the two rolling rollers, and aluminum foil can enter the gap. When the two rolling rollers rotate, the aluminum foil can be rolled to make the aluminum foil thinner. A conveying assembly (not shown in the figure) is arranged on the frame 100. The conveying assembly is used to convey the aluminum foil. The aluminum foil is continuously conveyed to between the two rolling rollers through the conveying assembly so that the aluminum foil rolling mill can work continuously. An oil spraying assembly is arranged on the frame 100. The oil spraying assembly can spray rolling oil on the surface of the rolling roller. The rolling oil forms an oil film between the rolling roller and the aluminum foil, which effectively reduces the direct contact between the aluminum foil and the rolling roller, thereby reducing friction. At the same time, it can effectively reduce the heat generated during the processing and prevent the surface of the aluminum foil from being deformed or burned due to high temperature.

[0024] The rolling oil in the prior art is generally sprayed directly between the two rolling rollers, so that the aluminum foil there can reduce friction and cool down during the rolling process. However, there is a lot of waste chips in the atmosphere in the production workshop. Therefore, when the rolling roller containing rolling oil moves on the surface of the aluminum foil, it is easy to be contaminated with certain waste chips, 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, the range directly sprayed between the two rolling rollers is small, resulting in a less than ideal cooling effect of the rolling roller.

[0025] Therefore, the present invention arranges the oil spray assembly on the side close to the two rolling rollers, and the oil spray assembly can circulate and spray the rolling oil from the rolling position close to the aluminum foil to the rolling rollers 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 to reduce the temperature of this position to the lowest. Then, when the two rolling rollers roll the aluminum foil, the temperature will not be too high. Therefore, the rolling oil is first sprayed there, and the cooling effect of the rolling oil is the best. When the rolling oil is sprayed onto the rolling rollers, the waste chips washed away will be mixed in the rolling oil, thereby having a certain cleaning effect on the waste chips on the surface of the rolling rollers. The oil spray assembly can recover most of the oil, and only a small part of the oil forms an oil film between the aluminum foil and the rolling rollers. In the process of most of the rolling oil reflux, the waste chips mixed in the rolling oil will be deposited at the bottom of the cavity. Then the rolling oil is circulated and sprayed at the rolling position away from the aluminum foil. The oil spray assembly can increase the area where the rolling oil cools the rolling rollers, and recycle the rolling oil to reduce the waste of rolling oil.

[0026] Specifically, the oil spray assembly in this embodiment includes a first oil spray box 210 and a second oil spray box 310. The first oil spray box 210 and the second oil spray box 310 are respectively located at the upper and lower rolling rollers and close to the position where the aluminum foil is rolled. Figure 6 , Figure 7 and Figure 8 As shown, for the convenience of description, the upper rolling roller is named as the first rolling roller 200, and the lower rolling roller is named as the second rolling roller 300. The upper end surface of the first spray box 210 is an arc surface so as to adapt to the first rolling roller 200, and the lower end surface of the second spray box 310 is also an arc surface so as to adapt to the second rolling roller 300. The first spray box 210 includes a plurality of first cavities 220. The plurality of first cavities 220 are arranged on the periphery of the first rolling roller 200 along the conveying direction of the aluminum foil (the conveying direction refers to Figure 6 A 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.

[0027] 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 6A 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.

[0028] 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.

[0029] It can be understood that most of the rolling oil sprayed 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 is then drawn away by the oil extraction pipe 270 and enters the next first oil injection pipe 230 or the second oil injection pipe 330, circulating in sequence, thereby recycling the rolling oil and increasing the area where the rolling oil is sprayed onto the rolling roller as a whole.

[0030] In a further embodiment, a partition 260 is disposed in each of the first cavity 220 and the second cavity 320. The partition 260 separates the first cavity 220 and the second cavity 320 into two chambers distributed along the conveying direction of the aluminum foil. Figure 7 and Figure 8As shown, the partition 260 separates the first cavity 220 and the second cavity 320 into two chambers distributed on the left and right, and 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 chamber on the left from the chamber on the right. In this process, larger impurities in the rolling oil are deposited at the bottom of the chamber under the action of gravity, and the oil extraction pipe 270 is arranged in the chamber on the opposite side of the aluminum foil conveying direction, that is, in the chamber on the left, specifically in the middle and upper position of the left chamber. When the rolling oil in the left chamber gradually increases, it is extracted through the oil extraction pipe 270, and the rolling oil extracted through the oil extraction pipe 270 enters another first oil injection pipe 230 or the second oil injection pipe 330.

[0031] It can be understood that the rolling oil is introduced into the first cavity 220 or the second cavity 320 on the far right, and the first oil injection pipe 230 or the second oil injection pipe 330 on the far right is connected to an oil conveyor (not shown in the figure), and the oil conveyor conveys the rolling oil to the first oil injection pipe 230 or the second oil injection pipe 330, and the rolling oil is sprayed from the oil injection hole to clean and cool the surfaces of the first rolling roller 200 and the second rolling roller 300. Most of the rolling oil will carry waste chips and flow back to the chamber on the right, and enter the chamber on the left after passing through the connecting position at the bottom of the partition 260. Part 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 rolling oil level in the left chamber gradually rises, the rolling oil at a higher position in the left chamber contains less waste chips, and the oil extraction pipe 270 inputs these rolling oils to the next first oil injection pipe 230 or the second In the oil injection pipe 330, since a large amount of heat is generated during the rolling of the aluminum foil, the first oil injection position is set at the position closest to the rolling of the aluminum foil, so that the rolling oil can fully cool the first rolling roller 200 and the second rolling roller 300. As the rolling oil circulates, the temperature of the rolling oil gradually increases, and finally it is discharged from the first cavity 220 or the second cavity 320 on the far left, specifically through the leftmost oil extraction pipe 270. The leftmost oil extraction pipe 270 is connected to an oil pump (not shown in the figure). The oil pump extracts the rolling oil, and the extracted rolling oil enters the cooling system (not shown in the figure) for cooling. At the same time, the cooling system also has a filtering function, so as to remove impurities in the rolling oil. The cooled and filtered rolling oil is re-input into the first cavity 220 or the second cavity 320 on the far right through the oil pump, so as to circulate.

[0032] It can be understood that the cooling system can be any cooling structure in the prior art, such as a cooling pipe. A cooler or a compressor is arranged on the periphery of the cooling pipe to reduce the temperature of the cooling pipe. The rolling oil extracted from the leftmost oil extraction pipe 270 is passed into the cooling pipe for cooling. Subsequently, a filtering mechanism such as a filter screen is also arranged in the cooling pipe to filter the cooled rolling oil. The filtered rolling oil is then passed into the first oil injection pipe 230 or the second oil injection pipe 330 on the rightmost side for recirculation.

[0033] It should be noted that if Figure 4 and Figure 5 As shown, an oil pump 400 is provided on one end of the first fuel injection pipe 230 or the second fuel injection pipe 330 and the oil extraction pipe 270 which are interconnected on the outside of the first fuel injection tank 210 or the second fuel injection tank 310. When the oil pump 400 is working, the rolling oil in the oil extraction pipe 270 can enter the first fuel injection pipe 230 or the second fuel injection pipe 330, and the rolling oil in the first fuel injection pipe 230 or the second fuel injection pipe 330 is sprayed out from the fuel injection hole under the action of the oil pump 400.

[0034] Specifically, the first inclined plate 240 is provided on the partition plate 260 in the first fuel injection tank 210 of the present invention, as shown in FIG. Figure 7 As shown, the first oil injection pipe 230 in the first oil injection box 210 is located above an end face of the first cavity 220 in the opposite direction of the aluminum foil conveying direction, that is, located above the left chamber, and the first inclined plate 240 is inclined toward the direction of the first oil injection pipe 230, and the oil injection hole is located above the first inclined plate 240, so that the rolling oil sprayed from the oil injection hole can pass through the first inclined plate 240 to enter the right chamber of the first cavity 220, preventing the rolling oil sprayed from the first oil injection pipe 230 from being directly sucked away by the oil extraction pipe 270 below. If the first inclined plate 240 is not provided, it will cause the first oil injection pipe 230 to The rolling oil sprayed from the pipe 230 hits the first rolling roller 200 and carries a large amount of waste chips into the oil extraction pipe 270, thereby making the function of depositing waste chips at the bottom of the first cavity 220 invalid. The first inclined plate 240 can avoid the above situation, so that the rolling oil first passes through the chamber on the right and then through the connecting position, and finally enters the left chamber. The liquid level of the rolling liquid in the left chamber gradually increases. In 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, thereby reducing the waste chip content in the rolling oil extracted by the oil extraction pipe 270.

[0035] In a further embodiment, the bottom of the first cavity 220 of the first oil spray box 210 is detachably arranged. When the aluminum foil press completes the aluminum foil rolling operation, the bottom of the first cavity 220 of the first oil spray box 210 can be removed. After removal, the waste chips deposited on the bottom can be cleaned and reinstalled, so that there is no waste chips at the bottom of the first cavity 220 during the next operation.

[0036] Specifically, a U-shaped bottom plate 280 is clamped at the bottom of the first cavity 220 , and the U-shaped bottom plate 280 can be removed from the bottom of the first cavity 220 , so as to facilitate cleaning of waste debris deposited in the first cavity 220 .

[0037] Specifically, the chamber of the second spray tank 310 on the side of the aluminum foil conveying direction is a special-shaped chamber, such as Figure 8 As shown, the L-shaped chamber 360 is specifically an L-shaped chamber 360, and the two ends of the L-shaped chamber 360 are close to the second rolling roller 300, and the second oil injection pipe 330 in the second oil injection box 310 is located outside the L-shaped chamber 360 and close to the second rolling roller 300, and the L-shaped chamber 360 is located on the side close to the aluminum foil conveying direction. The oil inlet 370 is opened, that is, the right side of the L-shaped chamber 360 is opened. When the second oil injection pipe 330 in the second oil injection box 310 starts to spray oil, the second rolling roller 300 rotates, and the rotation direction of the second rolling roller 300 is clockwise (with the oil inlet 370 being the same as the oil inlet 370 of the L-shaped chamber 360). Figure 8 The rolling oil sprayed on the surface of the second rolling roller 300 is driven by the second rolling roller 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 arranged 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 arranged above the oil inlet 370. The second inclined plate 340 is tangent to the outer periphery of the rolling roller, so that the rolling oil entering the L-shaped chamber 360 will not leak out. The rolling oil entering the L-shaped chamber 360 passes through the connecting position at the bottom of the partition 260 and then enters the chamber on the left. The liquid level of the rolling oil in the left chamber gradually increases. The oil extraction pipe 270 in the left chamber can extract the rolling liquid with increased height, thereby transporting it to another second oil injection pipe 330. The second oil injection pipe 330 recycles the rolling oil.

[0038] In a further embodiment, an adjustment component is provided on the frame 100, and the adjustment component can adjust the distance between the first rolling roller 200 and the second rolling roller 300. The adjustment component includes two slider groups, and each slider group includes two sliding blocks 110. The two sliding blocks 110 are respectively connected to the two ends of the first rolling roller 200 and the second rolling roller 300, and the first rolling roller 200 and the second rolling roller 300 are rotatably connected to the two sliding blocks 110. 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 roller 200 and the second rolling roller 300 to move away from or close to each other, thereby adjusting the distance between the first rolling roller 200 and the second rolling roller 300.

[0039] In a further embodiment, the frame 100 of the present invention is provided with a driving assembly, which can drive the first rolling roller 200 and the second rolling roller 300 to rotate around their own axes. Figure 6 As shown, the first rolling roller 200 rotates counterclockwise (in Figure 6 The second rolling roller 300 rotates clockwise (in the counterclockwise direction when viewed from the front to the back). Figure 6 (clockwise when viewed from front to back).

[0040] Specifically, the driving assembly includes a driving motor (not shown in the figure) and a transmission roller group. The transmission roller group includes two pairs of transmission rollers. For the convenience of description, the two pairs of transmission rollers are named as the first pair of transmission rollers and the second pair of transmission rollers 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 roller 120 is larger than the diameter of the second transmission roller 130. The driving motor is fixedly arranged on the frame 100. The outer periphery of the first transmission roller 120 is in rolling contact with the outer periphery of the second transmission roller 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 roller 120 to rotate, and the first transmission roller 120 drives the second transmission roller 130 to rotate. The two second transmission rollers 130 are in rolling contact with the first rolling roller 200 and the second transmission roller 130 at the same time, so that the second transmission roller 130 drives the first rolling roller 200 and the second rolling roller 300 to rotate.

[0041] It can be understood that providing multiple pairs of transmission rollers can improve the transmission accuracy, thereby making the rolling rollers rotate more accurately and improving the quality of aluminum foil rolling.

[0042] The specific working process of a rolling oil system of an aluminum foil rolling mill provided by the present invention is described in combination with the above embodiments: The oil conveyor (not shown in the figure), the oil pump 400 and the oil pumping unit (not shown in the figure) are started. The oil conveyor conveys the rolling oil to the first oil spray tank 210 and the second oil spray tank 310. The working state of the rolling oil in the first oil spray tank 210 is as follows: The rolling oil first passes through the first cavity 220 on the far right, and then is sprayed out from the first oil injection pipe 230 of the first cavity 220 on the far right, and then is sprayed toward the first rolling roller 200. After the rolling oil mixes with the waste on the surface of the first rolling roller 200, the pressing oil is driven to move toward the first scraper 250 close to the first cavity 220 under the action of the rotation of the first rolling roller 200. Since there is a very small gap between the first scraper 250 and the first rolling roller 200, the first scraper 250 can scrape most of the rolling oil, so that most of the rolling oil flows back into the first cavity 220, and only a small part of the rolling oil passes through the first scraper 250, so that there is only a thin layer of oil film on the surface of the first rolling roller 200, thereby improving the rolling quality of the aluminum foil, and the rolling oil flowing back into the first cavity 220 flows toward the gap. On the right side of the plate 260, that is, the chamber on the right side of the first cavity 220, the rolling oil enters the chamber on the left side through the connecting position below the partition 260. As the amount of oil injection increases, the rolling oil liquid level in the left chamber increases. In the process of increasing the rolling oil liquid level, 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 gradually approaches the oil extraction pipe 270, due to the action of the oil pump 400, the oil extraction pipe 270 can extract the rolling oil that exceeds the oil extraction pipe 270. The extracted rolling oil enters the first oil injection pipe 230 in another first cavity 220 through the oil pump 400. The flow state of the rolling oil in the first oil injection pipe 230 is the same as the flow state of the rolling oil in the first cavity 220 on the far right, which will not be elaborated here. The rolling oil flows continuously from right to left. The oil extraction pipe 270 in the leftmost cavity is connected to an oil pump, which extracts the rolling oil. The extracted rolling oil is cooled and then output again by the oil pump. The rolling oil re-enters the first oil injection pipe 230 in the rightmost first cavity 220, thus circulating.

[0043] The working state of the rolling oil in the second oil spray tank 310 is as follows: like Figure 8 As shown, the oil injection pipe in the second oil injection box 310 is located at the lower left of the L-shaped chamber 360. After the oil conveyor delivers the rolling oil to the second oil injection pipe 330, the rolling oil is sprayed out through the second oil injection pipe 330 and sprayed toward the second rolling roller 300. Due to the rotation of the second rolling roller 300, specifically clockwise (in Figure 8The second rolling roller 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 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 escaping from the L-shaped chamber 360. The rolling oil passes through the bottom of the partition 260 in the second cavity 320, and the rolling oil in the left chamber is discharged. The surface height gradually increases, and the waste mixed in the rolling oil is deposited at the bottom of the second cavity 320 under the action of gravity. The oil extraction pipe 270 in the left chamber extracts the rolling oil, and the rolling oil is delivered to the second oil injection pipe 330 connected thereto through the oil pump 400. The rolling oil is sprayed out from the oil injection hole under the action of the oil pump 400. The flow state of the rolling oil in the second cavity 320 is the same as the flow state of the rolling oil in the rightmost L-shaped chamber 360, and no further details are given here. The rolling oil flows continuously from right to left. The oil extraction pipe 270 in the leftmost second cavity 320 is connected to an oil pump, which extracts the rolling oil. The extracted rolling oil is cooled and cooled before being output by the oil pump again, and the rolling oil re-enters the oil injection pipe in the rightmost chamber, thus circulating.
