Description

Technical Field

[0001] The invention relates to aluminum plate surface degreasing equipment, belonging to the technical field of aluminum plate processing and manufacturing equipment. Background Art

[0002] In the rolling process of aluminum strips, the main function of rolling oil is to cool, lubricate and clean the rolls and aluminum strips. However, during production, the gap between the working rolls, the working rolls and the intermediate rolls, the ends of the intermediate rolls and the support rolls and the roll surfaces will flow or bring the rolling oil from the inlet side of the rolling mill to the outlet side, splashing onto the surface of the sheet. If the degreasing effect of the rolling mill does not meet the requirements during the entire sheet rolling process, a large amount of rolling oil and a large amount of aluminum powder will remain on the surface of the sheet, which will directly have a serious impact on the subsequent sheet surface. After annealing, butter spots, oil prints, oil stains, and dark luster will form on the surface of the sheet, directly affecting the surface quality of the product.

[0003] In view of the above technical problems, after searching, a Chinese patent with announcement number CN219664603U discloses a surface degreasing device for aluminum plates in a blanking process, and its technical key points are: it includes an upper telescopic cylinder, an upper scraper, an upper air nozzle, a lower telescopic cylinder, a lower scraper and a lower air nozzle; the upper telescopic cylinder is located above the blanking line roller, and the upper telescopic cylinder can drive the upper scraper to approach or move away from the aluminum plate running on the blanking line roller, and the upper air nozzle is facing the degreasing edge of the upper scraper and the edge of the aluminum plate; the lower telescopic cylinder is located below the blanking line roller, and the lower telescopic cylinder can drive the lower scraper to approach or move away from the aluminum plate running on the blanking line roller, and the lower air nozzle is facing the degreasing edge of the lower scraper and the edge of the aluminum plate.

[0004] For example, a Chinese patent with announcement number CN202989286U discloses an aluminum plate degreasing mechanism, the technical key points of which are: it includes a driving roller and at least one driven roller, the aluminum plate base moves around the rollers, and there are several alkali solution nozzles on the front and back of the aluminum plate base.

[0005] In the first solution, oil is removed by scraping and jetting, but the oil is highly sticky and often cannot be scraped off completely, leaving oil spots on the aluminum plate. In the second solution, the oil is cleaned by spraying cleaning fluid, but if the cleaning fluid and the oil on the aluminum plate need to be fully mixed, a large amount of cleaning fluid needs to be sprayed continuously, resulting in a waste of resources and excessively high costs.

When the wet cleaning roller descends, the sealing plate abuts against the bottom of the inner wall of the water outlet box under the action of the pressure spring, thereby closing the first water outlet hole and reducing the waste of cleaning liquid;

[0024] 3. By setting up a water absorption box, when the dry cleaning roller rises, it abuts against the scraper, so that the sewage absorbed by the absorbent cotton outside the dry cleaning roller is scraped off by the scraper, keeping it dry, improving the absorption efficiency of sewage, and making the surface of the aluminum plate cleaner after wet cleaning and dry cleaning;

[0025] 4. By setting a stirring piece between the wet cleaning roller and the dry cleaning roller, when the cleaning liquid on the wet cleaning roller is coated on the surface of the aluminum plate, the oil stains and the cleaning liquid are more fully mixed through the rotation of the soft hair, thereby further improving the cleaning effect of the aluminum plate, and by setting a folding hook at the end of the soft hair, the soft hair is not easy to throw out the sewage during the rotation process, splashing to other places, causing cleaning difficulties;

[0026] 5. By elastically slidingly connecting the two ends of the connecting rod to the first door frame and the second door frame respectively, when the swing frame drives the first door frame or the second door frame to descend, the wet cleaning roller and the dry cleaning roller can be pressed tightly against the surface of the aluminum plate, thereby reducing the situation of missed washing and incomplete washing and improving the cleaning effect.

[0048] When the rotary motor 55 rotates, it drives the driving belt 54 to rotate, and synchronously drives the first driving pulley 49 connected to the wet cleaning roller 10, the second driving pulley 52 connected to the dry cleaning roller 11, and the second driving pulley 52 connected to the long worm 51 to rotate synchronously, thereby causing the plurality of dry cleaning rollers 11, the plurality of wet cleaning rollers 10 and the plurality of stirring members 42 to rotate synchronously.

[0049] The implementation principle of the present invention is:

[0050] When the aluminum plate is pulled through the cleaning device 2 by the conveying device, the reciprocating screw 25 drives the cleaning box 5 to reciprocate. At this time, under the action of the counterweight 29, the swing frame 7 is driven to swing back and forth. When the wet cleaning roller 10 rises, the wet cleaning roller 10 absorbs the cleaning liquid in the water outlet box 12 on the absorbent cotton 17. When the wet cleaning roller 10 descends, it abuts against the surface of the aluminum plate. During the rotation, the cleaning liquid in the absorbent cotton 17 is squeezed and coated on the aluminum plate panel and fully mixed with the oil on the aluminum plate. When the dry cleaning roller 11 descends, the sewage on the surface of the aluminum plate is sucked into the absorbent cotton 17. Therefore, when the dry cleaning roller 11 rises, it rotates and abuts against the scraper 40, so that the sewage enters the water absorption box 13 and is discharged through the drain pipe 41. With the cooperation of the wet cleaning roller 10 and the dry cleaning roller 11, the oil can be scraped off, and the amount of cleaning liquid can be reduced, so that the cleaning liquid is fully mixed with the oil, thereby reducing the production cost.
