Description

Technical Field

[0001] The present invention relates to the technical field of aluminum foil rolling mills, and particularly to an aluminum foil rolling mill and a rolling method for aluminum foil production. Background Art

[0002] Aluminum foil is an extremely thin metal sheet made of pure aluminum or aluminum alloy through a rolling process, with a thickness usually less than 0.2 mm (Chinese standard). Its surface is smooth, with a silver-white metallic luster, soft texture and excellent ductility, and can be easily deformed and not easily rebound. The production process of aluminum foil is, in chronological order, aluminum ingot melting and casting, aluminum ingot rolling, aluminum plate winding, and finally aluminum plate rolling. Among them, the rolling of aluminum ingots is one of the important processes in aluminum foil production. During the process of rolling aluminum ingots into aluminum plates, impurities will be generated. Some of these impurities will be washed away by rolling oil, but some will remain on the surface of the aluminum ingots. If these impurities remaining on the surface of the aluminum ingots are not cleaned, they will be pressed into the aluminum plates during subsequent rolling, forming local defects, which will lead to poor quality of the rolled aluminum plates and thus affect the production quality of aluminum foil.

[0013] The present invention also provides a rolling method for aluminum foil production, using an aluminum foil rolling mill, and the specific steps are as follows: First, place the aluminum ingot to be processed on the loading roller table, and the loading roller table conveys the aluminum ingot to be processed to the unloading roller table. The spraying assembly sprays rolling oil on the aluminum ingot before rolling, so that the rolling roller performs the first rolling on the aluminum ingot.

After repeating the above steps several times, the aluminum ingot is rolled into an aluminum plate with a suitable thickness.

[0014] Compared with the prior art, the present invention provides an aluminum foil rolling mill and a rolling method for aluminum foil production, having the following beneficial effects: 1. The aluminum foil rolling mill and the rolling method for aluminum foil production. Through the arrangement of the cleaning mechanism, when the loading roller table and the unloading roller table cooperate with the rolling rollers on the frame to perform multiple rolling operations on the aluminum ingot, the cleaning mechanism drives the upper mounting plate to move downward through the adjusting component, so that the upper brush roller and the upper scraper on the upper mounting plate can always be in full contact with the upper surface of the aluminum ingot. Each time the thickness of the aluminum ingot is reduced by rolling, the upper scraper and the upper brush roller of the cleaning mechanism are always in full contact with the upper surface of the aluminum ingot, thereby effectively cleaning the surface of the aluminum ingot. Through the cooperation of the upper scraper and the upper brush roller and the lower scraper and the lower brush roller of the cleaning mechanism, the impurities and rolling oil on the surface of the aluminum ingot can be removed each time the aluminum ingot is rolled, thus preventing the impurities remaining on the surface of the aluminum ingot from being pressed into the aluminum plate during subsequent rolling, forming local defects, and making the quality of the rolled aluminum plate excellent, thereby improving the production quality of aluminum foil.

[0015] 2. The aluminum foil rolling mill and the rolling method for aluminum foil production. Through the cooperation of the upper support plate and the pressing spring and the lower support plate and the supporting spring, when the upper scraper abuts against the upper surface of the aluminum ingot, the pressing spring can apply a thrust to the upper support plate, and at the same time the supporting spring applies a thrust to the lower support plate, so that the upper scraper and the lower scraper are respectively in close contact with the upper surface and the lower surface of the aluminum ingot, thereby improving the cleaning effect of the impurities and rolling oil on the surface of the aluminum ingot. And when there are protrusions on the surface of the aluminum ingot, the upper scraper and the lower scraper can respectively make adaptive adjustments under the cooperation of the pressing spring and the supporting spring, so that after the protrusion part on the surface of the aluminum ingot passes, the upper scraper or the lower scraper can again abut against the surface of the aluminum ingot, preventing the upper scraper or the lower scraper from forcibly scraping the protrusion part on the surface of the aluminum ingot and causing damage to the surface of the aluminum ingot.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0019] Please refer to Figures 1-8 , an aluminum foil rolling mill and a rolling method for aluminum foil production, including a main body 1, the main body 1 includes a loading roller table 11, a frame 12, an unloading roller table 13, a cleaning mechanism 2, a collection component 5 and a spraying component 6. The loading roller table 11, the frame 12 and the unloading roller table 13 are connected in sequence. Two rolling rollers 121 are installed on the frame 12 in sequence. The rolling rollers 121 are used for rolling aluminum ingots. The cleaning mechanism 2 includes a mounting frame 21, an upper mounting plate 22, an adjusting component 3 and a lower mounting plate 4. The two mounting frames 21 are respectively connected to one ends of the loading roller table 11 and the unloading roller table 13 close to the frame 12. The upper mounting plate 22 and the lower mounting plate 4 are installed on the mounting frame 21 in sequence. An upper scraping plate 27 and an upper brush roller 28 are respectively installed on the upper mounting plate 22. The upper scraping plate 27 and the upper brush roller 28 are used for cleaning impurities on the upper surface of the aluminum ingot. A lower scraping plate 46 and a lower brush roller 47 are respectively installed on the lower mounting plate 4. The lower scraping plate 46 and the lower brush roller 47 are used for cleaning impurities on the lower surface of the aluminum ingot. Adjusting components 3 are arranged on both sides of the mounting frame 21. The adjusting components 3 cooperate with both ends of the upper mounting plate 22. The adjusting components 3 can drive the upper mounting plate 22 to move vertically on the mounting frame 21. The collection component 5 includes a collection tank 51. The collection tank 51 is installed below the cleaning mechanism 2 for collecting the removed impurities and rolling oil. The spraying component 6 is installed between the mounting frame 21 and the frame 12. The spraying component 6 is used for spraying rolling oil on the aluminum ingot.

[0020] Among them, during use, the aluminum ingot to be processed is placed on the loading roller table 11. The loading roller table 11 conveys the aluminum ingot to be processed towards the unloading roller table 13. At this time, the conveying directions of the loading roller table 11 and the unloading roller table 13 are the same. And the upper mounting plate 22 on the cleaning mechanism 2 is located at the upper end of the mounting frame 21. The distance between the upper scraping plate 27 and the upper brush roller 28 and the lower scraping plate 46 and the lower brush roller 47 can allow the aluminum ingot to be processed to pass through. When the aluminum ingot to be processed passes under the cleaning mechanism 2 on the loading roller table 11, the spraying components 6 on both sides of the frame 12 spray rolling oil onto the aluminum ingot. Subsequently, the aluminum ingot with rolling oil passes between the two rolling rollers 121 on the frame 12. The rolling rollers 121 perform the first rolling on the aluminum ingot, reducing the thickness of the aluminum ingot. The aluminum ingot passing between the two rolling rollers 121 enters the unloading roller table 13 and passes under the cleaning mechanism 2 on the unloading roller table 13. During this process, the cleaning mechanism 2 on the unloading roller table 13 starts to work. The adjusting component 3 on its mounting frame 21 drives the upper mounting plate 22 on this cleaning mechanism 2 to move downward, making the upper brush roller 28 and the upper scraping plate 27 on this upper mounting plate 22 contact the upper surface of the aluminum ingot. At the same time, the lower brush roller 47 and the lower scraping plate 46 on the lower mounting plate 4 of this cleaning mechanism 2 contact. As the aluminum ingot gradually passes under this cleaning mechanism 2, the upper brush roller 28 and the lower brush roller 47 rotate on the upper surface and the lower surface of the aluminum ingot respectively, brushing off the impurities generated during the rolling of the aluminum ingot surface. The aluminum ingot passing through the upper brush roller 28 and the lower brush roller 47 then passes between the upper scraping plate 27 and the lower scraping plate 46. At this time, the upper scraping plate 27 and the lower scraping plate 46 respectively abut against the upper surface and the lower surface of the aluminum ingot, shoveling the residual impurities and rolling oil on the aluminum ingot surface. As the aluminum ingot completely passes through this cleaning mechanism 2, the upper scraping plate 27 and the lower scraping plate 46 completely scrape off the impurities and rolling oil on the aluminum ingot surface. The scraped-off impurities and rolling oil will fall into the collection tank 51. Subsequently, the conveying directions of the unloading roller table 13 and the loading roller table 11 are changed. The unloading roller table 13 conveys the aluminum ingot towards the loading roller table 11 direction, making the aluminum ingot be rolled by the rolling rollers 121 again, thereby further reducing the thickness of the aluminum ingot. At the same time, the aluminum ingot passing under the rolling rollers 121 will enter the loading roller table 11. At this time, the cleaning mechanism 2 on the loading roller table 11 repeats the above steps. The adjusting component 3 drives the upper mounting plate 22 on this cleaning mechanism 2 to move downward, making the upper scraping plate 27 and the upper brush roller 28 contact the upper surface of the aluminum ingot. At the same time, the lower scraping plate 46 and the lower brush roller 47 contact the lower surface of the aluminum ingot, thereby cleaning the surface of the aluminum ingot again. After the aluminum ingot completely passes through this cleaning mechanism 2, the conveying directions of the loading roller table 11 and the unloading roller table 13 are changed again. The loading roller table 11 outputs the aluminum ingot to the unloading roller table 13, making the rolling rollers 121 perform another rolling on the aluminum ingot. At this time, the adjusting component 3 on the cleaning mechanism 2 on the unloading roller table 13 drives the upper mounting plate 22 to move further downward, making the upper scraping plate 27 and the upper brush roller 28 always contact the upper surface of the rolled aluminum ingot. After repeating the above steps several times like this, the aluminum ingot is rolled into an aluminum plate with a suitable thickness.At this time, the blanking roller table 13 sends the aluminum plate to the next process, thus completing the rolling work of the aluminum ingot.

[0021] The difference from the above embodiment is that the two mounting frames 21 are respectively fixedly mounted on the loading roller table 11 and the blanking roller table 13. A sliding groove 211 is formed in the mounting frame 21. A notch 2111 is formed on one side of the sliding groove 211 close to the machine frame 12. The notch 2111 penetrates through the side wall of the sliding groove 211. A fixing plate 212 is fixedly connected to the side wall of the mounting frame 21. The fixing plate 212 is located below the sliding groove 211.

[0022] The difference from the above embodiment is that an upper storage groove 221 is formed in the upper mounting plate 22. A number of uniformly arranged upper sleeves 23 are fixedly connected in the upper storage groove 221. An upper connecting rod 24 is slidably connected in the upper sleeve 23. The lower end of the upper connecting rod 24 is fixedly connected to an upper support plate 25. The upper end of the upper support plate 25 is fittingly installed in the storage groove. A pressing spring 26 is sleeved outside the upper sleeve 23. The two ends of the pressing spring 26 respectively abut against the top of the storage groove and the upper side of the upper support plate 25.

[0023] The difference from the above embodiment is that the upper scraper 27 is fixedly mounted on the lower side of the upper support plate 25. The upper brush roller 28 is rotatably mounted on the upper mounting plate 22. The upper brush roller 28 is located on the side of the upper scraper 27 close to the machine frame 12. A number of bristles are uniformly distributed on the upper brush roller 28. The rotating shaft at one end of the upper brush roller 28 extends out from the notch 2111 on the corresponding side of the mounting frame 21 and is coaxially fixedly connected to the output shaft of the driving motor 29.

[0024] Among them, when the aluminum ingot is rolled by the rolling roller 121, the adjusting assembly 3 pushes the upper mounting plate 22 downward, so that the bristles of the upper brush roller 28 on the upper mounting plate 22 are in full contact with the upper surface of the aluminum ingot. At the same time, the upper scraper 27 abuts against the upper surface of the aluminum ingot. When the scraper abuts against the upper surface of the aluminum ingot, the upper scraper 27 will push the upper support plate 25 to contract into the storage groove, so that the upper connecting rod 24 on the upper support plate 25 is retracted into the upper sleeve 23 by a corresponding length and compresses the pressing spring 26. The compressed pressing spring 26 thus exerts a thrust on the upper support plate 25, pressing the upper scraper 27 tightly against the upper surface of the aluminum ingot. During the cleaning process, the driving motor 29 drives the upper brush roller 28 to rotate. The rotating upper brush roller 28 brushes off the impurities on the upper surface of the aluminum ingot through the bristles on it. After the upper surface of the aluminum ingot passes through the cleaning of the upper brush roller 28, it passes under the upper scraper 27. The upper scraper 27 completely scrapes off the residual impurities and rolling oil on the upper surface of the aluminum ingot. After the rolling work of the aluminum ingot is completed, the adjusting assembly 3 drives the upper mounting plate 22 to move back to the top of the mounting frame 21, waiting for the processing of the next aluminum ingot. At the same time, the compressed pressing spring 26 restores its deformation and pushes out the part of the upper support plate 25 retracted in the storage groove.

[0025] The difference from the above embodiment is that the adjusting assembly 3 includes an adjusting motor 31 and a driving block 33. The adjusting motor 31 is arranged at the upper end of the sliding groove 211 and is fixedly connected to the mounting bracket 21. A coaxial adjusting screw 32 is fixedly connected to the output shaft of the adjusting motor 31. The adjusting screw 32 is rotatably installed in the sliding groove 211. The driving block 33 is slidably installed in the sliding groove 211 and is also threadedly assembled on the adjusting screw 32. The end of the mounting plate is fixedly connected to the driving block 33. A motor seat 34 is fixedly connected to the driving block 33 on the same side as the driving motor 29, and the driving motor 29 is fixedly installed on the motor seat 34.

[0026] Among them, when rolling an aluminum ingot, the adjusting motor 31 drives the adjusting screw 32 to rotate in the reverse direction, thereby driving the driving block 33 to move downward in the sliding groove 211, driving the upper mounting plate 22 to approach the upper surface of the aluminum ingot. After the rolling work of the aluminum ingot is completed, the adjusting motor 31 drives the adjusting screw 32 to rotate in the forward direction, thereby driving the driving block 33 to move upward in the sliding groove 211, driving the upper mounting plate 22 to move back to the top of the mounting bracket 21. When the driving block 33 drives the upper mounting plate 22 to move vertically on the mounting bracket 21, the driving block 33 also drives the driving motor 29 through the motor seat 34, and the frame 12 follows the upper mounting plate 22 to move synchronously.

[0027] The difference from the above embodiment is that the end of the lower mounting plate 4 is fixedly installed on the fixed plate 212. A lower receiving groove 41 is formed in the lower mounting plate 4. A number of uniformly arranged lower sleeves 42 are fixedly connected in the lower receiving groove 41. A lower connecting rod 43 is slidably connected in the lower sleeve 42. The upper end of the lower connecting rod 43 is fixedly connected to a lower support plate 44. The lower end of the lower support plate 44 is fittingly installed in the receiving groove. A support spring 45 is sleeved outside the lower sleeve 42, and both ends of the support spring 45 respectively abut against the bottom of the receiving groove and the lower side of the lower support plate 44.

[0028] The difference from the above embodiment is that the lower scraper 46 is fixedly installed on the upper side of the lower support plate 44. The lower brush roller 47 is rotatably installed on the lower mounting plate 4. The lower brush roller 47 is located on the side of the lower scraper 46 close to the frame 12. A number of bristles are evenly distributed on the lower brush roller 47, and one end of the lower brush roller 47 is coaxially fixedly connected to the output shaft of the motor 48. The motor 48 is fixedly installed on the main body 1.

[0029] Among them, when rolling aluminum ingots, the bristles of the lower brush roller 47 on the lower mounting plate 4 and the lower scraper 46 are always in full contact with the lower surface of the aluminum ingot. During this process, the support spring 45 pushes the lower support plate 44 upward, pressing the lower scraper 46 tightly against the lower surface of the aluminum ingot. During cleaning, the motor 48 drives the lower brush roller 47 to rotate. The rotating lower brush roller 47 brushes off the impurities on the lower surface of the aluminum ingot through the brushes on it. After the lower surface of the aluminum ingot is cleaned by the lower brush roller 47, it passes under the lower scraper 46, and the lower scraper 46 completely scrapes off the remaining impurities and rolling oil on the lower surface of the aluminum ingot.

[0030] The difference from the above embodiment is that the collection assembly 5 further includes a sewage pump 52. The collection tank 51 is fixedly connected to the main body 1, the sewage pump 52 is fixedly installed at the bottom of the collection tank 51, and the sewage pump 52 is communicated with the collection tank 51 through a pipeline.

[0031] Among them, when the rolling oil and impurities fall into the collection tank 51, the sewage pump 52 starts to discharge the rolling oil and impurities in the collection tank 51. Embodiment 2

[0032] The difference from the above embodiment is that the spraying assembly 6 includes a spray pipe 61 and spray nozzles 62. The spray pipe 61 is fixedly installed between the mounting frame 21 and the frame 12. The spray pipe 61 is located at the upper end of the frame 12, and a plurality of spray nozzles 62 are uniformly arranged on the spray pipe 61. The spray nozzles 62 are fixedly connected to the spray pipe 61.

[0033] Among them, the spray pipe 61 conveys the rolling oil to each spray nozzle 62, and the spray nozzles 62 uniformly spray the rolling oil on the aluminum ingot.

[0034] The present invention also provides a rolling method for aluminum foil production, which uses an aluminum foil rolling mill. The specific steps are as follows: First, place the aluminum ingot to be processed on the loading roller table 11. The loading roller table 11 conveys the aluminum ingot to be processed to the unloading roller table 13. The spraying assembly 6 sprays rolling oil onto the aluminum ingot before rolling, enabling the rolling roller 121 to perform the first rolling on the aluminum ingot. The aluminum ingot after the first rolling enters the unloading roller table 13 and passes under the cleaning mechanism 2 of the unloading roller table 13. Meanwhile, the adjusting assembly 3 on the cleaning mechanism 2 drives the upper scraping plate 27 and the upper brush roller 28 to always be in full contact with the upper surface of the aluminum ingot, so that the upper and lower surfaces of the aluminum ingot are cleaned under the cooperation of the upper scraping plate 27 and the upper brush roller 28 and the lower scraping plate 46 and the lower brush roller 47. When the aluminum ingot completely passes through the cleaning mechanism 2, the unloading roller table 13 and the loading roller table 11 change the conveying direction. The unloading roller table 13 conveys the aluminum ingot after the first rolling towards the loading roller table 11 for the second rolling. When the aluminum ingot after the second rolling returns to the loading roller table 11, the cleaning mechanism 2 on the loading roller table 11 repeats the above steps to clean the upper and lower surfaces of the aluminum ingot again. After the aluminum ingot is cleaned, the loading roller table 11 and the unloading roller table 13 change the conveying direction again to perform the third rolling on the aluminum ingot. After repeating the above steps several times, the aluminum ingot is rolled into an aluminum plate with a suitable thickness.

[0035] Working principle: During use, place the aluminum ingot to be processed on the loading roller table 11. The loading roller table 11 conveys the aluminum ingot to be processed towards the unloading roller table 13. At this time, the conveying directions of the loading roller table 11 and the unloading roller table 13 are the same, and the upper mounting plate 22 on the cleaning mechanism 2 is located at the upper end of the mounting frame 21. The distance between the upper scraping plate 27 and the upper brush roller 28 and the lower scraping plate 46 and the lower brush roller 47 can allow the aluminum ingot to be processed to pass through. When the aluminum ingot to be processed passes under the cleaning mechanism 2 on the loading roller table 11, the spraying assemblies 6 on both sides of the frame 12 spray rolling oil onto the aluminum ingot. Subsequently, the aluminum ingot with rolling oil on it passes between the two rolling rollers 121 on the frame 12. The rolling rollers 121 perform the first rolling on the aluminum ingot, reducing the thickness of the aluminum ingot. The aluminum ingot passing between the two rolling rollers 121 enters the unloading roller table 13 and passes under the cleaning mechanism 2 of the unloading roller table 13. During this process, the cleaning mechanism 2 on the unloading roller table 13 starts to work. The adjusting motor 31 on its mounting frame 21 drives the adjusting screw 32 to rotate in the reverse direction, thereby driving the driving block 33 to move downward in the sliding groove 211, driving the upper mounting plate 22 to approach the upper surface of the aluminum ingot, and making the upper brush roller 28 and the upper scraping plate 27 on the upper mounting plate 22 contact the upper surface of the aluminum ingot; When the scraper touches the upper surface of the aluminum ingot, the upper scraper 27 will push the upper support plate 25 to contract into the storage groove, causing the upper connecting rod 24 on the upper support plate 25 to retract into the upper sleeve 23 by a corresponding length and compress the pressing spring 26. The compressed pressing spring 26 thus exerts a thrust on the upper support plate 25, pressing the upper scraper 27 tightly against the upper surface of the aluminum ingot. During cleaning, the driving motor 29 drives the upper brush roller 28 to rotate. The rotating upper brush roller 28 brushes off the impurities on the upper surface of the aluminum ingot through the brushes on it. After the upper surface of the aluminum ingot is cleaned by the upper brush roller 28, it will pass under the upper scraper 27. The upper scraper 27 completely scrapes off the residual impurities and rolling oil on the upper surface of the aluminum ingot. As the aluminum ingot completely passes through this cleaning mechanism 2, the upper scraper 27 and the lower scraper 46 completely scrape off the impurities and rolling oil on the surface of the aluminum ingot. The scraped-off impurities and rolling oil will fall into the collection tank 51. Subsequently, the feeding roller table 13 and the loading roller table 11 change the conveying direction; The feeding roller table 13 conveys the aluminum ingot towards the loading roller table 11, enabling the aluminum ingot to be rolled again by the rolling roller 121, thereby further reducing the thickness of the aluminum ingot. At the same time, the aluminum ingot passing under the rolling roller 121 will enter the loading roller table 11. At this time, the cleaning mechanism 2 on the loading roller table 11 repeats the above steps. The adjusting component 3 drives the upper mounting plate 22 on this cleaning mechanism 2 to move downward, causing the upper scraper 27 and the upper brush roller 28 to contact the upper surface of the aluminum ingot, and at the same time, the lower scraper 46 and the lower brush roller 47 to contact the lower surface of the aluminum ingot, thereby cleaning the surface of the aluminum ingot again. After the aluminum ingot completely passes through this cleaning mechanism 2, the conveying directions of the loading roller table 11 and the feeding roller table 13 change again. The loading roller table 11 outputs the aluminum ingot to the feeding roller table 13, enabling the rolling roller 121 to perform another rolling on the aluminum ingot. At this time, the adjusting component 3 on the cleaning mechanism 2 on the feeding roller table 13 drives the upper mounting plate 22 to move further downward, causing the upper scraper 27 and the upper brush roller 28 to always contact the upper surface of the rolled aluminum ingot. After repeating the above steps several times like this, the aluminum ingot is rolled into an aluminum plate with a suitable thickness. At this time, the feeding roller table 13 sends the aluminum plate to the next process, thus completing the rolling work of this aluminum ingot.
