Description

Technical Field

[0001] This invention relates to the field of aluminum foil rolling mill equipment, and specifically to an air-blowing hot air hook plate structure for aluminum foil rolling mills. Background Technology

[0002] Aluminum foil rolling is a precision plastic forming process that uses flat rolls to cold roll aluminum or aluminum alloy billets into ultra-thin foils. During the rolling process, aluminum foil rolling mills are used to roll aluminum sheets and strips into ultra-thin aluminum foils.

[0003] A large amount of rolling oil is used in the rolling process. The main functions of the rolling oil are cooling, lubrication and cleaning. During the rolling process, a large amount of rolling oil will stick to the rolls. If it is not cleaned in time, a large amount of sludge will be generated. The sludge will stick firmly to the surface of the rolls. During rolling, it will be transferred to the surface of the aluminum foil through the rolls, causing catastrophic quality problems. The most typical example is the formation of "annealing oil spots" that cannot be removed in the subsequent annealing process.

[0004] Existing methods for cleaning the surface of rolls involve installing a scraper at the bottom of the roll. As the roll rotates, the scraper removes the rolling oil from the surface. However, some of the rolling oil turns into sludge that adheres firmly to the surface. In this case, the scraper cannot remove it smoothly, and sometimes forced scraping can even damage the scraper. Therefore, a new type of roll surface cleaning structure is needed to solve this problem. Summary of the Invention

[0005] The present invention addresses the technical problems mentioned in the background section and proposes the following technical solutions: A hot air hook plate structure for air purging in an aluminum foil rolling mill includes a hook plate holder, a swing hook plate, a hook plate, a side baffle, and an adjusting rod. The hook plate holder is rotatable. The top of the swing hook plate is fixedly connected to the other end of the hook plate holder. The hook plate is installed below the swing hook plate. The side baffle is connected below the hook plate. One end of the adjusting rod is connected to the swing hook plate. The adjusting rod is telescopic and will drive the swing hook plate to rotate around one end of the hook plate holder during telescopic movement. A cavity is provided between the swing hook plate and the hook plate. A hot air inlet is provided on the swing hook plate and communicates with the cavity. A pressure cap is provided at the front end of the swing hook plate. An air outlet is provided on the pressure cap and the front end of the hook plate and communicates with the cavity. A scraper is provided on the pressure cap.

[0006] Preferably, the cavity gradually decreases in size from right to left.

[0007] Preferably, an oil baffle is provided above the adjusting rod, and an oil receiving tray is provided on the side baffle, with the oil receiving tray located directly below the oil baffle.

[0008] Preferably, a sealing ring is provided between the swing hook plate and the pressure cap.

[0009] Preferably, the pressure cap has a beveled edge structure on the side near the front end of the hook plate.

[0010] The beneficial effects of this invention are: 1. By setting an air outlet on the hook plate that can blow out hot air, and then introducing hot air into the swinging hook plate, the hot air passes through the cavity and is finally blown out through the air outlet. This allows for preliminary cleaning of the rolls with hot air, which can blow away a large area of ​​rolling oil on the roll surface and heat the sludge to soften it before it is scraped clean by a scraper. Compared with existing cleaning devices, this method has a better cleaning effect, and the hot air can also soften the sludge so that it can be removed by the scraper, avoiding the problem of scraper damage that may occur when scraping sludge in existing devices.

[0011] 2. By setting up oil baffles and oil receiving trays, some oil and water will condense when they encounter the oil baffles due to the high temperature of the plate surface after rolling. They will then drip onto the oil receiving tray and flow down the sides of the tray without dripping onto the plate surface.

[0012] 3. By setting a sealing ring, rolling oil can be prevented from seeping into the cavity through the gap between the swing hook plate and the pressure plate. If the seeping rolling oil seeps in, it will block the air outlet for a long time, preventing hot air from being blown out of the air outlet. This will prevent the roller surface from being initially cleaned, and will lead to problems such as the roller surface not being cleaned properly or the accumulated oil sludge causing damage to the scraper.

[0013] 4. The pressure cap is set with a beveled structure on the side near the front of the hook plate. The beveled structure makes the air outlet wider at the top and narrower at the bottom, and the air pressure will be higher when hot air is blown out, which can remove more rolling oil.

[0018] Example 1 Reference Figure 1-2 A hot air hook plate structure for air blowing in an aluminum foil rolling mill includes a hook plate holder 1, a swing hook plate 2, a hook plate 3, a side baffle 4, and an adjusting rod 5. The hook plate holder 1 is rotatable. The top of the swing hook plate 2 is fixedly connected to the other end of the hook plate holder 1. The hook plate 3 is installed below the swing hook plate 2, and the side baffle 4 is connected below the hook plate 3. One end of the adjusting rod 5 is connected to the swing hook plate 2. The adjusting rod 5 is telescopic and will drive the swing hook plate 2 to rotate around the hook plate holder 1 during the telescopic process. A cavity 6 is provided between the swing hook plate 2 and the hook plate 3. A hot air inlet 2-1 is provided on the swing hook plate 2 and communicates with the cavity 6. A pressure cover 7 is provided at the front end of the swing hook plate 2. An air outlet 8 is provided at the front end of the pressure cover 7 and the hook plate 3 and communicates with the cavity 6. A scraper 7-1 is provided on the pressure cover 7.

[0019] Preferably, the cavity 6 gradually decreases in size from right to left.

[0020] In actual operation, hot air is introduced into the hot air inlet 2-1, and the hot air will pass through the cavity 6 and be blown out from the air outlet 8. In this way, before the scraper 7-1 scrapes the oil off the roller surface, a large area of ​​rolling oil can be blown away first, and then the scraper 7-1 can be used to scrape it clean. Compared with the existing cleaning device, this method has a better cleaning effect. Using hot air for cleaning can also avoid the problem of some rolling oil forming sludge that sticks to the roller surface and is difficult to scrape off.

[0021] Example 2 Reference Figure 1The difference between this embodiment and embodiment one is that an oil baffle 9 is provided above the adjusting rod 5, and an oil receiving tray 10 is provided on the side baffle 4. The oil receiving tray 10 is located directly below the oil baffle 9. Some oil and water will condense after encountering the oil baffle 9 due to the high temperature of the plate surface after rolling. Then, as the hot air rises from the plate surface, the oil and water will drip onto the oil receiving tray 10 and flow along both sides of the oil receiving tray 10 without dripping onto the plate surface.

[0022] Example 3 Reference Figure 1-2 The difference between this embodiment and embodiment one is that a sealing ring 11 is provided between the swing hook plate 2 and the pressure cover 7. Some rolling oil will fall on the swing hook plate 2 and seep into the cavity 6 through the gap between the swing hook plate 2 and the pressure cover 7, causing the cavity 6 to be blocked. By providing the sealing ring 11, the entry of rolling oil into the cavity 6 can be reduced or even avoided.

[0023] Example 4 Reference Figure 1-2 The pressure cap 7 has a beveled structure on the side near the front end of the hook plate 3. The beveled structure makes the air outlet wider at the top and narrower at the bottom, and the air pressure will be higher when hot air is blown out, which can remove more rolling oil.
