Description

Technical Field

[0001] This utility model relates to the field of aluminum foil rolling mill technology, and in particular to an air purging and oil removal device for aluminum foil rolling mill. Background Technology

[0002] During the aluminum foil rolling process, a large amount of process lubricating oil (currently mainly kerosene) is carried away from the rolling zone along with the aluminum material, remaining on the upper and lower surfaces of the aluminum foil. If degreasing is not performed at the exit of the rolling guide rolls, the entire roll of aluminum foil will easily become oily, causing roll slippage and severely affecting the production efficiency of the rolling mill and the surface quality of the finished aluminum foil strip. Therefore, degreasing is a crucial factor directly affecting the performance of the rolling mill. Currently, degreasing devices in the aluminum plate rolling industry mainly use air purging, but the existing air purging degreasing devices have unreasonable structural designs, causing oil to accumulate towards the center of the material surface, resulting in incomplete degreasing. This leads to a high oil content in the finished aluminum foil strip, high costs, and unstable product quality. Therefore, this application provides an air purging degreasing device for aluminum foil rolling mills to solve the above-mentioned technical problems. Utility Model Content

[0003] This utility model provides an air-blowing oil removal device for aluminum foil rolling mills, which can smoothly blow the lubricating oil in the center area of ​​the material surface to both sides. The blowing nozzles on both sides blow the lubricating oil away from the material surface, avoiding the lubricating oil from accumulating in the center of the material surface, which would lead to excessive oil volume and residue. This can improve the oil removal effect and enhance product quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An air purging and oil removal device for an aluminum foil rolling mill includes a mounting base located at the outlet of the rolling guide roll, and a purging mechanism mounted on the mounting base. The purging mechanism includes a main air pipe, a plurality of purging nozzles, and a plurality of control valves. The main air pipe is fixedly connected to the mounting base in a horizontal direction, and the main air pipe has an air inlet end connected to an external air pressure supply pipeline. The air inlets of the plurality of purging nozzles are all connected to the main air pipe, and the air outlet end of each purging nozzle is inclined downward and aligned with the aluminum foil exiting from the outlet of the rolling guide roll. Each control valve is mounted on one of the purging nozzles and is used to control the airflow magnitude of the purging nozzle. The plurality of purging nozzles are arranged side by side, and the airflow magnitude of the purging nozzles decreases progressively from the middle to the sides.

[0006] Furthermore, the purge nozzle located in the middle of the main air pipe is vertically connected to the main air pipe, and the remaining purge nozzles are symmetrically distributed with the purge nozzle in the middle of the main air pipe as the bisector. Each of the remaining purge nozzles is arranged at an angle toward the corresponding side of the main air pipe, so that the purge nozzles form a fan-shaped layout.

[0007] Furthermore, the number of purge nozzles is at least three, with the middle purge nozzle vertically connected to the main air pipe and the other two purge nozzles obliquely connected to the main air pipe, arranged in a fan-shaped layout with the middle purge nozzle as the center.

[0008] Furthermore, the purging nozzle includes a nozzle and a connecting pipe, one end of which is sealed and welded to the main air pipe and communicates with the main air pipe; the other end of the connecting pipe is connected to the nozzle; and the control valve is installed on the connecting pipe.

[0009] Furthermore, the control valve of the middle purge nozzle is opened to 100%, while the control valves of the other two purge nozzles are opened to 60%.

[0010] Furthermore, the aluminum foil rolling mill air purging and oil removal device further includes an oil blocking mechanism; the oil blocking mechanism includes a first oil blocking plate arranged above the aluminum foil at the outlet of the rolling guide roll, an oil collecting groove located below the aluminum foil, and second oil blocking plates distributed on both sides of the outlet of the rolling guide roll; wherein one of the second oil blocking plates is fixedly connected to one side of the first oil blocking plate and the oil collecting groove, and the other second oil blocking plate is fixedly connected to the other side of the first oil blocking plate and the oil collecting groove.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses air blades formed by side-by-side blowing nozzles on the blowing mechanism to blow away the lubricating oil on the surface of aluminum foil. With the help of the control valve, the airflow in the middle is greater than the airflow on both sides, so that the lubricating oil in the center area of ​​the material surface is smoothly blown to both sides. The blowing nozzles on both sides blow the lubricating oil away from the material surface, avoiding the lubricating oil from accumulating in the center of the material surface and causing excessive oil accumulation and residue. This can improve the degreasing effect and improve product quality.

[0013] 2. The aforementioned blowing nozzles form a fan-shaped layout, with the airflow being stronger in the middle and gradually decreasing at both ends. This allows the lubricating oil in the center of the material surface to be smoothly blown away to both sides, improving the oil removal effect and reducing the oil content on the material surface.

[0014] 3. The oil baffle mechanism can prevent lubricating oil from splashing at the purging position, and the first oil baffle can also block the oil thrown over from above the roll. Attached Figure Description

[0023] Reference Figures 1 to 2As shown, an air purging and degreasing device for an aluminum foil rolling mill includes a mounting base 1 located at the outlet of the rolling guide roll, and a purging mechanism 2 mounted on the mounting base 1. The purging mechanism 2 includes a main air pipe 21, a plurality of purging nozzles 22, and a plurality of control valves 23. The main air pipe 21 is fixedly connected to the mounting base 1 in a horizontal direction and is perpendicular to the conveying direction of the aluminum foil 3. The main air pipe 21 is provided with an air inlet end connected to an external air pressure supply pipeline. The air inlets of the plurality of purging nozzles 22 are all connected to the main air pipe 21. The air outlet end of each purging nozzle 22 is inclined downward and aligned with the aluminum foil 3 exiting from the outlet of the rolling guide roll. Each control valve 23 is mounted on one of the purging nozzles 22 and is used to control the purging. The airflow magnitude of the nozzle 22; several purge nozzles 22 are arranged side by side and aligned. The purge nozzle 22 located in the middle of the main air pipe 21 is vertically connected to the main air pipe 21. The remaining purge nozzles 22 are symmetrically distributed with the purge nozzle 22 in the middle of the main air pipe 21 as the bisector. Each of the remaining purge nozzles 22 is inclined towards the corresponding side of the main air pipe 21, so that the several purge nozzles 22 form a fan-shaped layout. The airflow magnitude of the several purge nozzles 22 from the middle to the two sides gradually decreases. The purge nozzles 21 form a fan-shaped layout, and the airflow is greater in the middle and gradually decreases at both ends. This can smoothly blow the lubricating oil in the center of the material surface to both sides, improve the oil removal effect, and reduce the oil content of the material surface.

[0024] In this embodiment, Figure 2 As shown, the number of purge nozzles 22 is at least three. The middle purge nozzle 22 is vertically connected to the main air pipe 21, and the other two purge nozzles 22 are obliquely connected to the main air pipe 21, arranged in a fan-shaped layout symmetrically with the middle purge nozzle 22 as the center nozzle. The control valve of the middle purge nozzle 21 has an opening of 100%, and the control valves of the other two purge nozzles 22 have an opening of 60%. Each purge nozzle 22 includes a nozzle 221 and a connecting pipe 222. One end of the connecting pipe 222 is sealed and welded to the main air pipe 21 and communicates with the main air pipe 21; the other end of the connecting pipe 222 is connected to the nozzle 221; and the control valve 23 is installed on the connecting pipe 222. All three purging nozzles 22 are tilted towards the material surface, forming a purging angle of about 30° with the horizontal line of the material surface. Compressed air from the external supply pipeline is distributed to the three purging nozzles through the main air pipe 21 and sprayed out through the purging nozzles. The air sprayed from the middle purging nozzle has a larger air force, while the air sprayed from the purging nozzles at both ends has a smaller air force. This can sweep the lubricating oil in the center area of ​​the material surface to both ends, while the oil at both ends is blown away from the material surface. There will be no phenomenon of the air force at the left and right ends blowing the lubricating oil back to the center area, thus avoiding the phenomenon of oil accumulation in the center of the material surface.

[0025] The aforementioned air-blowing oil removal device for an aluminum foil rolling mill further includes an oil-blocking mechanism 4. The oil-blocking mechanism 4 includes a first oil-blocking plate 41 positioned above the aluminum foil 3 at the outlet of the rolling guide roll, an oil collection trough 42 positioned below the aluminum foil 3, and second oil-blocking plates 43 distributed on both sides of the outlet of the rolling guide roll. One second oil-blocking plate 43 is fixedly connected to one side of the first oil-blocking plate 41 and the oil collection trough 42, and the other second oil-blocking plate 43 is fixedly connected to the other side of the first oil-blocking plate 41 and the oil collection trough 42. The first oil-blocking plate 41 is 1 cm away from the outer wall of the upper work roll at the outlet of the guide roll. The oil-blocking mechanism 4 prevents lubricating oil from splashing at the blowing position, and the first oil-blocking plate 41 also blocks oil thrown from above the rolling roll. The oil collection trough 42 collects the lubricating oil blown away from the surface of the aluminum foil 3. The second oil-blocking plates 43 prevent lubricating oil from splashing to both sides.

[0026] This invention uses air blades formed by the parallel air-blowing nozzles 22 on the air-blowing mechanism 2 to blow away the lubricating oil on the surface of the aluminum foil 3. With the regulation of the control valve 23, the airflow in the middle is greater than that on both sides, so that the lubricating oil in the center area of ​​the material surface is smoothly blown to both sides. The air-blowing nozzles on both sides blow the lubricating oil away from the material surface, avoiding the lubricating oil from accumulating in the center of the material surface and causing excessive oil accumulation and residue. This can improve the degreasing effect and improve product quality.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
