Description

Technical Field

[0001] This utility model relates to the field of aluminum foil rolling mill technology, specifically to a cleaning nozzle and an aluminum foil rolling mill exit flattening roll cleaning system. Background Technology

[0002] Aluminum foil rolling mills are key equipment in the production of battery foil, characterized by high efficiency, high precision, and high stability. The mill presses aluminum foil material into the desired battery foil through the rotation and pressing of rollers. Its working principle involves the coordinated action of three rollers: the upper, middle, and lower rollers, with the upper and lower rollers being the main rollers and the middle roller being the slave roller. After the aluminum foil material is pressed by the main rollers, it is further pressed by the slave rollers, ultimately transforming the material into the desired battery foil. As a crucial material for battery current collectors, the production of battery foil involves complex processes such as casting and rolling, with the foil rolling process being the key factor determining the final quality and performance of the aluminum foil.

[0003] As an indispensable component of aluminum foil rolling mills, flattening rolls are currently available on the market. During the aluminum foil rolling process, some impurities such as aluminum ash may adhere to the surface of the flattening rolls, affecting the quality of the aluminum foil. This necessitates cleaning the surface of the flattening rolls. Traditional nozzles can generally only achieve a single lubrication function, and additional equipment is required to clean the surface of the flattening rolls.

[0004] A search revealed that utility model CN220127205U provides an aluminum rolling mill outlet purging device, including a diversion device and an oil collection tank. The diversion device is closely attached to the aluminum foil and is set at a certain angle to the surface of the aluminum foil, allowing the oil on the aluminum foil surface to be guided by the inclined plane. The diversion device includes an upper diversion block and a lower diversion block. The end of the upper diversion block is connected to the oil collection tank, and the lower diversion block is provided with a diversion groove, the opening of which is connected to the oil collection tank. However, this device cannot effectively remove impurities such as aluminum ash adhering to the aluminum foil surface, and the amount of oil sprayed from the nozzle cannot be precisely controlled, resulting in significant waste. Summary of the Invention

[0005] To address the issue that impurities such as aluminum ash may adhere to the surface of the flattening roll during the traditional aluminum foil rolling process, affecting the quality of the aluminum foil, and that existing nozzles cannot precisely control the composition of the sprayed oil mist and can only achieve a single function, this invention proposes a cleaning nozzle and an aluminum foil rolling mill exit flattening roll cleaning system to solve the above problems.

[0006] A cleaning nozzle includes a housing. The surface of the housing is provided with an oil inlet port, a first air inlet port, and a second air inlet port. A wind cap is installed at one end of the housing. A needle valve is provided inside the housing near the end of the wind cap. A needle valve body is fitted to the end of the needle valve near the wind cap. The needle valve body is fitted with an annular hole located on the end face of the housing near the wind cap. An oil cavity is provided between the needle valve body and the inner surface of the housing. An oil passage is provided inside the housing. The oil cavity and the oil inlet port are connected through the oil passage.

[0007] The oil chamber is surrounded by a purge air chamber, which is equipped with a limiting hole. The limiting hole is located on the end face of the shell near the wind cap. The limiting holes are evenly and symmetrically distributed around the annular hole. The purge air chamber is connected to an air passage, which is connected to the purge air chamber and the second air pipe interface.

[0008] Furthermore, an arc-shaped protrusion is provided on one side of the wind cap, and multiple corner holes are provided on the lower surface of the arc-shaped protrusion. The corner holes are connected to an adjusting air chamber, which is located inside the wind cap and is directly connected to the first air pipe interface. By setting up a separate air chamber, which is connected to an independent air supply pipe, the oil mist sprayed from the nozzle can be precisely controlled by adjusting the control terminal. This allows it to adapt to different working environments, improve overall work efficiency, and reduce waste. For example, in some scenarios, the edge area of ​​the aluminum foil requires less lubricating oil than the center area. By controlling the control terminal, the composition of the sprayed oil mist can be changed, reducing oil waste while lubricating the edge area of ​​the aluminum foil.

[0009] Furthermore, a locking nut is installed at the end of the housing away from the hood, and a push rod is installed inside the locking nut. An adjusting spring is connected to the end of the needle valve away from the hood. One end of the adjusting spring is movably connected to the needle valve, and the other end of the adjusting spring is movably connected to one end of the push rod. An adjusting bolt is provided so that it can be manually adjusted.

[0010] Furthermore, the other end of the top rod is connected to an adjusting bolt. One end of the adjusting bolt extends into the housing, and the end of the adjusting bolt extending into the housing is threaded. An adjusting nut is fitted to the thread, and the adjusting nut is located inside the locking nut. The inner surfaces of the adjusting nut and the locking nut are fixedly connected.

[0011] Furthermore, the needle valve body, needle valve, and push rod are all made of wear-resistant materials or have undergone wear-resistant treatment; this increases service life and prevents metal debris from entering the air duct and causing blockage.

[0012] Furthermore, limiters are installed on the outer surface of the housing, a filter screen is installed at the opening of the oil inlet pipe interface, a threaded sleeve is provided at the connection between the air cap and the housing, and sealing rings are provided at the connection between the housing, the air cap, and the locking nut; to enhance the sealing, the threaded sleeve is provided for easy disassembly and assembly, and to facilitate maintenance.

[0013] The system also includes a cleaning system for the flattening rolls at the exit of an aluminum foil rolling mill, using the aforementioned nozzles. This system comprises a control terminal and a first fixed frame. Nozzles are linearly mounted on the surface of the first fixed frame. Fixing members are connected to both ends of the first fixed frame, and a second fixed frame connects adjacent fixing members. Both the first and second fixed frames are equipped with multiple intermediate connecting pipes, the positions of which correspond one-to-one with the nozzle positions. The first fixed frame allows for the suspension of an appropriate number of nozzles based on specific usage conditions, improving the overall applicability of the system.

[0014] Furthermore, each nozzle is individually connected to an oil inlet pipe, a purge air pipe, and a control air pipe. The oil inlet pipe and its interface are fixedly connected, the purge air pipe and its second air pipe interface are fixedly connected, and the control air pipe and its first air pipe interface are fixedly connected.

[0015] Furthermore, one end of the oil inlet pipe is fixedly connected to a nozzle, and the other end of the oil pipe is connected to an oil tank. An electric diaphragm pump is installed between the nozzle and the oil tank, and a valve is connected between the electric diaphragm pump and the nozzle.

[0016] Furthermore, both the purge air pipe and the control air pipe are connected to an air source. The air source output is equipped with a filter and a pressure gauge. The purge air pipe is connected to a three-way solenoid valve, and the control air pipe is connected to a pressure reducing valve and a two-way solenoid valve. A pressure gauge is installed between the pressure reducing valve and the two-way solenoid valve. Through the regulation of the control terminal and in cooperation with the electric diaphragm pump, after debugging, the system can accurately control the composition of the oil mist sprayed from the nozzle, realizing functions such as lubrication and cleaning without replacing the nozzle or using additional devices, thus having greater applicability.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Precise control and adaptability: By setting up separate air chambers and independent air supply pipes, as well as precise control of the control terminal, the system can accurately control the composition of the oil mist sprayed from the nozzle according to the needs of different working environments, and realize multiple functions such as lubrication and cleaning, without the need to replace the nozzle or use additional devices, which greatly improves the adaptability and working efficiency of the system.

[0019] 2. Flexibility and scalability: The modular design allows multiple nozzles to be linearly installed on the first and second mounting brackets. Users can select the appropriate number of nozzles according to their specific needs, easily expanding the system scale to meet the requirements of various application scenarios.

[0020] 3. Durability and Ease of Maintenance: Key components such as the needle valve body, needle valve, and push rod are made of wear-resistant materials or have undergone wear-resistant treatment, extending their service life. Meanwhile, the design of limiting components, filter screens, threaded sleeves, and sealing rings on the outer surface of the housing enhances sealing performance and facilitates disassembly and maintenance, reducing maintenance costs.

[0021] 4. High Efficiency, Energy Saving, and Environmental Protection: By controlling the air and oil chambers of the control terminal and separately connecting the air and oil supply pipes, the composition of the oil mist can be precisely controlled, effectively reducing unnecessary waste and improving energy efficiency. Simultaneously, the inclusion of filters, pressure gauges, and other components ensures the purity and stability of the air source, which is beneficial to environmental protection. For example, in some scenarios, the edge areas of aluminum foil require less lubricating oil than the center areas. By controlling the control terminal to change the composition of the sprayed oil mist, oil waste is reduced while lubricating the edge areas of the aluminum foil.

[0022] 5. Intelligent and automated: By combining automated components such as electric diaphragm pumps, valves, three-way solenoid valves, pressure reducing valves, and two-way solenoid valves, as well as intelligent control of the control terminal, the system achieves a high degree of automation and intelligence, reduces the difficulty of manual operation, improves work efficiency, and reduces fuel waste.

[0034] The application principle of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figure 1-8 The image shows a cleaning nozzle and a cleaning system for the flattening roll at the exit of an aluminum foil rolling mill. The cleaning nozzle includes a housing 506. The surface of the housing 506 is provided with an oil inlet port 501, a first air pipe port 503, and a second air pipe port 508. A wind cap 504 is installed at one end of the housing 506.

[0040] The other end of the top rod 13 is connected to an adjusting bolt 505. One end of the adjusting bolt 505 extends into the housing 506. The end of the adjusting bolt 505 that extends into the housing 506 is threaded. The threaded end is fitted with an adjusting nut 15. The adjusting nut 15 is located inside the locking nut 14. The adjusting nut 15 and the inner surfaces of the locking nut 14 are fixedly connected.

[0041] The needle valve body 8, needle valve 11, and push rod 13 are all made of wear-resistant materials or have undergone wear-resistant treatment.

[0042] A cleaning system for the flattening roll at the outlet of an aluminum foil rolling mill includes a housing 506. A limiting element 502 is installed on the outer surface of the housing 506. A filter screen is installed at the opening of the oil inlet pipe interface 501. A threaded sleeve 507 is provided at the connection between the air cap 504 and the housing 506. A sealing ring is provided at the connection between the housing 506, the air cap 504, and the locking nut 14.

[0043] It includes a control terminal and a first fixed frame 1. The first fixed frame 1 has nozzles 5 linearly mounted on its surface. The first fixed frame 1 has fixing members 2 connected to both ends. A second fixed frame 3 is connected between adjacent fixing members 2. The first fixed frame 1 and the second fixed frame 3 are only provided with multiple intermediate connecting pipes 4. The positions of the intermediate connecting pipes 4 correspond one-to-one with the positions of the nozzles 5.

[0044] Each nozzle 5 is individually connected to an oil inlet pipe, a purge air pipe, and a control air pipe. The oil inlet pipe and the oil inlet pipe interface 501 are fixedly connected. The purge air pipe and the second air pipe interface 508 are fixedly connected. The control air pipe and the first air pipe interface 503 are fixedly connected.

[0045] One end of the oil inlet pipe is fixedly connected to the nozzle 5, and the other end of the oil pipe is connected to the oil tank 16. An electric diaphragm pump 17 is provided between the nozzle 5 and the oil tank 16, and a valve 18 is connected between the electric diaphragm pump 17 and the nozzle 5.

[0046] Both the purge air pipe and the control air pipe are connected to an air source 19. The output end of the air source 19 is equipped with a filter 20 and a pressure gauge 21.

A pressure gauge 21 is installed between the pressure reducing valve 23 and the two-way solenoid valve 24.

[0047] Example 2

[0048] like Figure 1-8 As shown: When nozzle 5 is working, electric diaphragm pump 17 starts, air source 19 starts, electric diaphragm pump 17 pumps high-pressure oil into oil chamber 802, and pushes needle valve body 8 away from annular hole 801 to push needle valve 11 to compress adjusting spring 12, releasing needle valve body 8 from annular hole 801, so that high-pressure oil is sprayed out from annular hole 801 to form small oil droplets. At the same time, high-pressure air is injected from air source 19 into housing 506 through second air pipe interface 508, and enters the blower through air passage 9 inside housing 506. In the scavenging chamber 7, the oil mist is formed by mixing with small oil droplets through the limiting hole 701 and is driven to move. At the same time, high-pressure air enters the regulating chamber 6 from the air source 19 through the first air pipe interface 503 and is sprayed out through the corner hole 601, limiting the diffusion range of the oil mist. When the high-pressure oil is gradually sprayed out from the annular hole 801, the pressure is not enough to resist the elastic force of the regulating spring 12. The regulating spring 12 pushes the needle valve 11 to move closer to the annular hole 801, pushing the needle valve body 8 to block the annular hole 801, thus completing one oil injection.

[0049] Furthermore, according to a preset program, the control terminal controls the flow rate of high-pressure air and high-pressure oil in the pipeline by controlling the three-way solenoid valve 22, the two-way solenoid valve 24, and the valve 18 for nozzles 5 at different positions, thereby regulating the range of oil mist components sprayed from nozzles 5 at different positions.
