Description

Technical Field

[0001] This invention belongs to the field of cold rolling mill technology, specifically relating to a cold rolling mill for aluminum plates with a novel oiling device. Background Technology

[0002] Aluminum foil, as a raw material in industrial manufacturing, is widely used in various fields, primarily in packaging protection, daily necessities, and construction. During aluminum foil processing, aluminum strips need to be rolled multiple times in a cold rolling mill to form coils with a thickness of less than 0.5mm. During rolling, sliding friction inevitably occurs between the aluminum strip and the pressure rollers, resulting in surface scratches, black oil lines, and other quality issues that affect product quality. The current solution is to install an oiling device at the cold rolling mill inlet to apply mill oil to the aluminum strip, improving the friction between the strip and the pressure rollers.

[0003] Most current oiling devices spray mill oil onto aluminum plates using a nozzle device, and then use a scraper or oiling roller to spread the oil evenly. For example, patent application number CN202211051790.7 discloses an aluminum foil rolling mill capable of automatically and evenly applying oil. Its structure includes a rolling mill body, with an oiling mechanism on each side of the rolling mill body. The oiling mechanism includes a connecting arm, a mounting plate, an oil spraying assembly, and a spreading assembly. The mounting plate is connected to the rolling mill body through the connecting arm. An oil spraying assembly is mounted on the mounting plate, and a spreading assembly is located on the side of the oil spraying assembly closest to the rolling mill body. During rolling, the aluminum strip is guided into the rolling mill body, and the oil spraying assembly operates simultaneously, spraying rolling oil onto both sides of the aluminum strip. The spreading assembly then spreads the rolling oil evenly before the rolling mill body rolls the aluminum strip. This device can evenly adhere the rolling oil to the aluminum strip, preventing damage to the aluminum foil during rolling and effectively saving resources and reducing production costs. However, this device still has some problems. For example, when using the oil spraying assembly to spray the rolling oil onto the aluminum strip surface, in order to ensure that the spreading assembly can coat the entire surface of the aluminum strip, the oil spraying assembly still needs to spray an excessive amount of rolling oil onto the aluminum strip. Only after the spreading assembly can the rolling oil be evenly coated, resulting in a complex structure. Furthermore, the oil spraying assembly is located in an open space, and there is no effective means of recovering the rolling oil, causing significant oil loss and polluting the machine environment, which brings considerable disruption to production.

[0004] Therefore, in view of the above-mentioned shortcomings, this application proposes an aluminum plate cold rolling mill with a novel oiling device that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an aluminum plate cold rolling mill with a novel oiling device, thereby effectively solving the problems existing in the prior art.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows: A cold rolling mill for aluminum sheets with a novel oiling device includes a mill body. A worktable is located on the feed side of the mill body. Mounting platforms are vertically and symmetrically arranged on the worktable. An oiling box device is fixedly mounted on the mounting platforms. Sealing devices are symmetrically arranged on the front and rear sides of the oiling box device. The aluminum sheet strip passes through the sealing devices and enters the oiling box device to be coated with mill oil. It then passes through the sealing devices again before entering the mill for rolling. Atomizing boxes are symmetrically arranged above and below the oiling box device. A fan device connects the atomizing box device and the oiling box device. The air outlet of the fan device is connected to… The oiling box device is connected to the air inlet and the atomizing box device. The left and right ends of the oiling box device are connected to the atomizing box device through air pipes. After the rolling mill oil is atomized by the atomizing box device, it is evenly diffused inside the atomizing box device. The fan device blows the atomized rolling mill oil in the atomizing box device into the oiling box device to contact the upper and lower surfaces of the aluminum strip, directly and evenly applying the rolling mill oil to the aluminum strip in one go, avoiding excessive application and waste. The remaining rolling mill oil mist in the oiling box device is circulated back to the atomizing box device through the air pipe, realizing the closed-loop recycling of the rolling mill oil and avoiding oil mist contamination of the machine.

[0007] As a further provision of the above scheme, the oiling box device includes an oiling box, with a through oiling chamber at the center of the oiling box. A fan device is symmetrically installed on the upper and lower ends of the oiling chamber. The fan device is a bladeless straight-cylinder fan to prevent the rolling mill oil from condensing on the fan device. Circulating air pumps are provided on the left and right sides of the oiling chamber, and the circulating air pumps are connected to the atomizing box device through air pipes.

[0008] As a further provision of the above solution, the sealing device includes a sealing plate body, a sealing vertical plate, and a sealing horizontal plate. The sealing plate body has a through groove in its center. Mounting brackets are symmetrically arranged on both sides of the sealing plate body. Double-headed studs are rotatably connected to the mounting brackets. Screw blocks are provided on both sides of the sealing vertical plate. The sealing vertical plate is connected to the double-headed studs through the screw blocks. The sealing vertical plates are symmetrically arranged on the double-headed studs. When the double-headed studs on both sides are rotated synchronously, the two sealing vertical plates move synchronously relative to each other or towards each other. A horizontal guide roller is rotatably installed on the bottom end face of the sealing vertical plate. A U-shaped clearance groove with an opening facing downward is opened between the horizontal guide roller and the screw blocks.

[0009] As a further feature of the above solution, a support plate perpendicular to the sealing plate body is provided between the mounting bracket and the through groove. The support plates are symmetrically arranged and located between the clearance grooves. A vertical guide post and a spring are provided on the inner side of the support plate. One end of the sealing horizontal plate is slidably connected to the guide post and fixedly connected to the spring. The other end of the sealing horizontal plate is rotatably connected to a vertical guide roller. The sealing horizontal plate and the sealing vertical plate are parallel to each other and in sliding contact. When the aluminum strip needs to pass through the oiling box device and the sealing device, the double-headed studs rotate synchronously, driving the seal through the screw blocks. The vertical plates move relative to each other, the two horizontal guide rollers move away from each other, compressing and fixing the spring. The sealing horizontal plate contacts the support plate. At this time, a rectangular channel is formed between the horizontal and vertical guide rollers. After the aluminum strip passes through it, the double-headed stud reverses, causing the sealing vertical plates to move towards each other. The two horizontal guide rollers approach each other and finally contact the top and bottom surfaces of the aluminum strip. The spring is released, and the sealing horizontal plates move towards each other on the guide post. The two vertical guide rollers approach each other and finally contact the left and right surfaces of the aluminum strip. At this time, the sealing device seals the aluminum strip in the oiling tank device to prevent oil mist leakage when applying rolling mill oil.

[0010] As a further provision of the above solution, the atomizing box device includes an atomizing box, which is a closed rectangular box. The atomizing box has mounting ears on both sides and is fixed to the mounting platform by the mounting ears. An atomizer is provided on the upper surface of the atomizing box. An atomizing nozzle is connected to the lower end of the atomizer and is located inside the atomizing box. An air pipe is connected to the upper end of the atomizer and is connected to a circulating air pump.

[0011] As a further feature of the above scheme, an oil pump is provided next to the atomizer. The oil pump is connected to the atomizer and is equipped with an oil extraction device and an oil inlet. The oil extraction device penetrates into the atomization box and is connected to the inner wall of the atomization box. The oil pump supplies rolling mill oil to the atomizer through the oil inlet. At the same time, a circulating air pump supplies gas from the oil coating box to the atomizer through an air pipe. The atomizer re-atomizes the rolling mill oil and the oil mist in the oil coating box through the atomizing nozzle, ensuring uniform distribution of rolling mill oil mist and constant air pressure in the atomization box.

[0012] As a further configuration of the above scheme, if the atomizing box device is located above the oiling box device, the oil extraction device is configured as oil extraction device one, which penetrates into the atomizing box and is connected to the inner wall of the bottom plate of the atomizing box. If the atomizing box device is located below the oiling box device, the oil extraction device is configured as oil extraction device two, which penetrates into the atomizing box and is connected to the inner wall of the top plate of the atomizing box. The function of oil extraction device one and oil extraction device two is to extract the condensed mill oil in the atomizing box and recycle it, so as to avoid the accumulation of mill oil and affect the operation of the atomizing nozzle.

[0013] As a further feature of the above solution, the lower end of the atomizing box is connected to the air inlet of the fan device. A filter cover is provided at the air inlet of the fan device. The filter cover is conical and has filter holes on its surface. The filter cover prevents the oil mist in the atomizing box from directly entering the fan device, thus ensuring the normal operation of the fan device.

[0014] The beneficial effects of this invention are: When this equipment is working, the double-headed studs first rotate synchronously, driving the sealing vertical plates to move relative to each other through the stud blocks. The two horizontal guide rollers move away from each other, compressing and fixing the springs. The sealing horizontal plates contact the support plates, forming a rectangular channel between the horizontal and vertical guide rollers. After the aluminum strip passes through, the double-headed studs reverse, driving the sealing vertical plates to move towards each other. The two horizontal guide rollers approach each other and finally contact the top and bottom surfaces of the aluminum strip. The springs are released, and the sealing horizontal plates move towards each other on the guide posts. The two vertical guide rollers approach each other and finally contact the left and right sides of the aluminum strip. At this time, the sealing device seals the aluminum strip in the oiling tank.

[0015] The oil pump is started to supply rolling mill oil to the atomizer. The atomizer atomizes the rolling mill oil through the atomizing nozzle and sprays it into the atomization box. The rolling mill oil is evenly distributed in the atomization box. At the same time, the blower and circulating air pump are started. The blower draws the oil mist from the atomization box into the coating box. The oil mist comes into contact with the aluminum strip to complete the coating. Because the circulating air pump is working simultaneously, excess oil mist moves to both sides after contacting the aluminum strip. After being pressurized by the circulating air pump, the excess oil mist and air in the coating box return to the atomizer through the air pipe, realizing the recovery of rolling mill oil while ensuring stable air pressure in the atomization box and coating box. The two circulating air pumps have the same power and are connected to the atomization box device separately. The upper and lower atomization boxes operate in the same state to ensure the uniformity of oil coating on both sides of the aluminum strip. When the rolling mill oil in the atomization box condenses to a certain extent, oil extraction devices one and two extract the rolling mill oil and supply it back to the atomizer through the oil pump, realizing the automatic recovery and recycling of rolling mill oil.

[0016] This invention incorporates an oil coating box and a sealing device to ensure a closed environment during the rolling mill oil spraying process, preventing oil leakage and contamination of the machine and reducing oil consumption. Additionally, an atomizing box, in conjunction with a fan, delivers oil mist into the oil coating box to contact the aluminum strip. The structure is simple, ensuring even coating, and automatically returns excess oil mist to the atomizing box, enabling automatic oil recovery and recycling, thus reducing production costs.

A mounting platform 3 is vertically and symmetrically arranged on the worktable 2. An oiling box device 5 is fixedly installed on the mounting platform 3. Sealing devices 6 are symmetrically arranged on the front and rear sides of the oiling box device 5. The aluminum strip 4 passes through the sealing device 6 and enters the oiling box device 5 to be coated with mill oil. After passing through the sealing device 6 again, it enters the mill body 1 for rolling. Atomizing box devices 8 are symmetrically arranged above and below the oiling box device 5. A fan device 7 connects the atomizing box device 8 and the oiling box device 5. The air outlet of the fan device 7 is connected to the oiling box device 5. The oiling box device 5 is connected to the air inlet and the atomizing box device 8. The left and right ends of the oiling box device 5 are connected to the atomizing box device 8 through air pipes 805 respectively. After the rolling mill oil is atomized by the atomizing box device 8, it is evenly diffused in the atomizing box device 8. The fan device 7 blows the atomized rolling mill oil in the atomizing box device 8 into the oiling box device 5 to contact the upper and lower surfaces of the aluminum strip 4, directly and evenly applying the rolling mill oil to the aluminum strip 4 in one go, avoiding excessive application. The remaining rolling mill oil mist in the oiling box device 5 is circulated back to the atomizing box device 8 through the air pipe 805, realizing the closed-loop recycling of the rolling mill oil and avoiding oil mist contamination of the machine.

[0022] like Figure 3 , Figure 4 As shown, the oiling box device 5 includes an oiling box 501, with a through oiling chamber 502 at the center of the oiling box 501. A fan device 7 is symmetrically installed on the upper and lower ends of the oiling chamber 502. The fan device 7 is a bladeless straight-tube fan to prevent the rolling mill oil from condensing on the fan device 7. A circulating air pump 503 is provided on the left and right sides of the oiling chamber 502. The circulating air pump 503 is connected to the atomizing box device 8 through an air pipe 805.

[0023] like Figure 5 , Figure 6 As shown, the sealing device 6 includes a sealing plate body 601, a sealing vertical plate 604, and a sealing horizontal plate 605. The sealing plate body 601 has a through groove in the center. Mounting brackets 602 are symmetrically arranged on both sides of the sealing plate body 601. Double-headed studs 6021 are rotatably connected to the mounting brackets 602. Screw blocks 6041 are arranged on both sides of the sealing vertical plate 604. The sealing vertical plate 604 is connected to the double-headed studs 6021 through the screw blocks 6041. The sealing vertical plate 604 is symmetrically arranged on the double-headed studs 6021. When the double-headed studs 6021 on both sides are rotated synchronously, the two sealing vertical plates 604 move synchronously relative to each other or towards each other. A horizontal guide roller 6042 is rotatably installed on the bottom end face of the sealing vertical plate 604. A U-shaped clearance groove 6043 with an opening facing downward is opened between the horizontal guide roller 6042 and the screw block 6041.

[0024] A support plate 603, perpendicular to the sealing plate body 601, is provided between the mounting bracket 602 and the through groove. The support plates 603 are symmetrically arranged and located between the clearance grooves 6043. A vertical guide post and a spring are provided on the inner side of the support plate 603. One end of the sealing horizontal plate 605 is slidably connected to the guide post and fixedly connected to the spring. The other end of the sealing horizontal plate 605 is rotatably connected to a vertical guide roller 6051. The sealing horizontal plate 605 and the sealing vertical plate 604 are parallel to each other and in sliding contact. When the aluminum strip 4 needs to pass through the oiling box device 5 and the sealing device 6, the double-headed stud 6021 rotates synchronously, driving the sealing vertical plate 604 to move relative to each other through the screw block 6041. The horizontal guide rollers 6042 move away from each other, compressing and fixing the springs. The sealing horizontal plate 605 contacts the support plate 603. At this time, a rectangular channel is formed between the horizontal guide rollers 6042 and the vertical guide rollers 6051. After the aluminum strip 4 passes through it, the double-headed stud 6021 reverses, causing the sealing vertical plate 604 to move towards each other. The two horizontal guide rollers 6042 approach each other and finally contact the upper and lower surfaces of the aluminum strip 4. The springs are released, and the sealing horizontal plate 605 moves towards each other on the guide post. The two vertical guide rollers 6051 approach each other and finally contact the left and right surfaces of the aluminum strip 4. At this time, the sealing device 6 seals the aluminum strip 4 in the oiling tank device 5 to prevent oil mist leakage when applying rolling mill oil.

[0025] like Figure 7As shown, the atomizing box device includes an atomizing box 801, which is a closed rectangular box. Mounting ears 802 are provided on both sides of the atomizing box 801, and the atomizing box 801 is fixed to the mounting platform 3 via the mounting ears 802. An atomizer 804 is provided on the upper surface of the atomizing box 801, and an atomizing nozzle 8041 is connected to the lower end of the atomizer 804. The atomizing nozzle 8041 is located inside the atomizing box 801, and an air supply is connected to the upper end of the atomizer 804. Pipe 805 is connected to the circulating air pump 503. Next to the atomizer 804, there is an oil pump 803, which is connected to the atomizer 804. The oil pump 803 has an oil extraction device and an oil inlet 8032. The oil extraction device penetrates into the atomizing box 801 and is connected to the inner wall of the atomizing box 801. The oil pump 803 supplies mill oil to the atomizer 804 through the oil inlet 8032. Simultaneously, the circulating air pump 503 supplies oil through pipe 805. The gas in the oiling box 501 is supplied to the atomizer 804. The atomizer 804 re-atomizes the rolling mill oil and the oil mist in the oiling box through the atomizing nozzle 8041, ensuring the uniform distribution of the rolling mill oil mist and constant air pressure in the atomizing box 801. If the atomizing box device 8 is located above the oiling box device 5, the oil extraction device is set as oil extraction device one 8031. Oil extraction device one 8031 ​​penetrates into the interior of the atomizing box 801 and is connected to the inner wall of the bottom plate of the atomizing box 801. If the atomizing box device 8 is located below the oiling box device 5, the oil extraction device is set as oil extraction device two 8033. Oil extraction device two 8033 penetrates into the interior of the atomizing box 801 and is connected to the inner wall of the top plate of the atomizing box 801. The function of oil extraction device one 8031 ​​and oil extraction device two 8033 is to extract the condensed rolling mill oil in the atomizing box 801 and recycle it, so as to avoid the accumulation of rolling mill oil and affect the operation of the atomizing nozzle 8041.

[0026] like Figure 8 As shown, the lower end of the atomizing box 801 is connected to the air inlet of the fan device 7. A filter cover 701 is provided at the air inlet of the fan device 7. The filter cover 701 is conical and has filter holes on its surface. The filter cover 701 prevents the oil mist in the atomizing box 801 from directly entering the fan device 7, thus ensuring the normal operation of the fan device 7.

[0027] The working principle of this invention is as follows: When the aluminum strip 4 is applied, the double-headed studs 6021 rotate synchronously, driving the sealing vertical plates 604 to move relative to each other through the screw blocks 6041. The two horizontal guide rollers 6042 move away from each other, compressing and fixing the spring. The sealing horizontal plate 605 contacts the support plate 603. At this time, a rectangular channel is formed between the horizontal guide rollers 6042 and the vertical guide rollers 6051. After the aluminum strip 4 passes through it, the double-headed studs 6021 reverse, driving the sealing vertical plates 604 to move towards each other. The two horizontal guide rollers 6042 approach each other and finally contact the top and bottom surfaces of the aluminum strip 4. The spring is released, and the sealing horizontal plates 605 move towards each other on the guide posts. The two vertical guide rollers 6051 approach each other and finally contact the left and right surfaces of the aluminum strip 4. At this time, the sealing device 6 applies oil to the aluminum strip 4 in the oiling tank device 5. The system is sealed, and the oil pump 803 is started to supply rolling mill oil to the atomizer 804. The atomizer 804 atomizes the rolling mill oil through the atomizing nozzle 8041 and sprays it into the atomization box 801. The rolling mill oil is evenly diffused in the atomization box 801. At the same time, the fan device 7 and the circulating air pump 503 are started. The fan device 7 draws the oil mist in the atomization box 801 into the oiling box 501. The oil mist comes into contact with the aluminum strip 4 to complete the oiling. Since the circulating air pump 503 is working at the same time, the excess oil mist will move to both sides after contacting the aluminum strip 4. After being pressurized by the circulating air pump 503, the excess oil mist and the air in the oiling box 501 return to the atomizer 804 through the air pipe, realizing the recovery of rolling mill oil while ensuring the stability of the air pressure in the atomization box 801 and the oiling box 501.

It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
