Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil processing equipment, and in particular to a surface degreasing device for aluminum foil processing. Background Technology

[0002] As is well known, during the aluminum foil rolling process, a large amount of rolling oil adheres to its surface for lubrication and cooling. Subsequent processing steps require the thorough removal of this oil, especially for high-end applications such as food packaging and electronic foil, where surface cleanliness is of paramount importance.

[0003] Chinese patent CN219520042U describes an aluminum foil surface degreasing device, comprising an degreasing tank, a partition, a first laying roller, and a second laying roller. The partition divides the degreasing tank into an degreasing chamber and a clean water chamber. The degreasing chamber is equipped with a degreasing component, and the clean water chamber is equipped with a rinsing component. However, in actual use, the following problems still exist: Conventional degreasing methods use chemical degreasing cleaning lines, but for heavy oil stains, the degreasing solution is difficult to fully dissolve in a short time, resulting in incomplete cleaning. In particular, the lower surface of the aluminum foil is in a semi-enclosed state, and the oil stains peeled off from this surface are blocked by the aluminum foil body, which easily forms a barrier film. At the same time, it hinders the diffusion of emulsion products into the main solution, making the cleaning process slow and reducing the cleaning efficiency of heavy oil stains.

[0004] Therefore, a surface degreasing device for aluminum foil processing is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a surface degreasing device for aluminum foil processing.

One end of the rotating shaft 7 is rotatably connected to the bearing slider 8.

[0020] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the lower surface cleaning assembly includes a rotating roller 11 and a guide member. The rotating roller 11 has a guide cavity inside, and the two ends of the guide cavity are connected to the degreasing liquid tank 1. The rotating roller 11 is sleeved on the rotating shaft 7, and the inner wall of the rotating roller 11 is connected to the outer wall of the rotating shaft 7 through the guide member. The rotating roller 11 has a plurality of guide holes 12, which are evenly distributed on the rotating roller 11 and are connected to the guide cavity. The outer wall of the rotating roller 11 is provided with an oil scraping groove 13, and the outer wall of the rotating roller 11 is in contact with the lower surface of the aluminum foil 5.

[0021] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, there are two flow guides, and the two flow guides are located at both ends of the inner wall of the rotating roller 11. The flow guide includes a fan blade 14. There are several fan blades 14, and the fan blades 14 are evenly distributed circumferentially along the axis of the rotating roller 11. One end of the fan blade 14 is fixedly connected to the inner wall of the rotating roller 11, and the other end of the fan blade 14 is fixedly connected to the outer wall of the rotating shaft 7.

[0022] like Figure 6 As shown, the flow guiding cavity includes a truncated conical flow guiding cavity 15 and a cylindrical flow guiding cavity 16. There are two truncated conical flow guiding cavities 15. The large-diameter ends of the two truncated conical flow guiding cavities 15 are connected to the degreasing liquid tank 1. The two ends of the cylindrical flow guiding cavity 16 are respectively connected to the small-diameter ends of the two truncated conical flow guiding cavities 15, and the cross-sectional area of ​​the cylindrical flow guiding cavity 16 is equal to the cross-sectional area of ​​the small-diameter end of the truncated conical flow guiding cavity 15.

[0023] like Figure 4 As shown, the oil scraper groove 13 is a double spiral shape.

[0024] like Figure 2 and Figure 7As shown, the excitation assembly includes a vibrating plate 17, a rotating ring 18, and a vibrating protrusion 19. The vibrating plate 17 is located between the rotating roller 11 and the inlet drive roller 2, and is located below the aluminum foil 5. The two ends of the vibrating plate 17 are fixedly connected to the two sides of the inner wall of the degreasing liquid tank 1, respectively. The inner wall of the rotating ring 18 is located between the rotating roller 11 and the inner wall of the degreasing liquid tank 1 and is fixedly connected to the outer wall of the rotating shaft 7. One end of the vibrating protrusion 19 is fixedly connected to the outer wall of the rotating ring 18, and the other end of the vibrating protrusion 19 is in contact with the vibrating plate 17.

[0025] The work process is as follows: S1. In use, start the inlet drive roller 2 and the outlet drive roller 3. Driven by the inlet drive roller 2 and the outlet drive roller 3, the aluminum foil 5 moves along a predetermined path in the degreasing tank 1 under the guidance of the two submerged rollers 4. The upper surface of the aluminum foil 5 is brushed by the roller brush 6. The elastic force of the elastic telescopic column 9 pushes the bearing slider 8 upward. Through the cooperation of the rotating shaft 7 and the fan blade 14, the rotating roller 11 is made to fit against the lower surface of the aluminum foil 5. When the rotating shaft 7 rotates, it drives the rotating ring 18 and the vibrating protrusion 19 on the rotating shaft 7 to rotate synchronously. The vibrating protrusion 19 periodically actuates the vibrating plate 17, causing the vibrating plate 17 to vibrate. The vibration generated by the vibrating plate 17 is transmitted to the lower surface of the aluminum foil 5 through the liquid medium, preventing the formation of a barrier film on the outer layer of emulsified heavy oil stains, allowing the degreasing liquid to continuously contact and dissolve the oil stains, while loosening the stubborn oil stains on the surface of the aluminum foil 5, improving the dissolution efficiency of the oil stains. The vibration generated by the vibrating plate 17 and transmitted to the lower surface of the aluminum foil 5 through the liquid medium avoids the formation of a barrier film caused by emulsified oil stains, thus improving the dissolution efficiency of the degreasing liquid on heavy oil stains.

[0026] S2, when the aluminum foil 5 passes through the rotating roller 11, the motion friction of the lower surface of the aluminum foil 5 drives the rotating roller 11 to rotate. The double spiral oil scraping groove 13 on the outer wall of the rotating roller 11 scrapes off the oil stains on the lower surface of the aluminum foil 5 during the rotation. At this time, the rotating shaft 7 is fixedly connected to the rotating roller 11 through the fan blade 14, so that the fan blade 14 rotates synchronously. The rotating fan blade 14 generates negative pressure in the guide cavity inside the rotating roller 11, and the oil stains scraped off by the oil scraping groove 13 are sucked into the guide cavity of the rotating roller 11 through the guide hole 12, thereby removing the oil stains on the lower surface of the aluminum foil 5. The scraping by the oil scraping groove 13 on the rotating roller 11 and the negative pressure generated by the fan blade 14 work together to avoid the secondary adhesion and incomplete removal of the loosened and scraped heavy oil stains, thus improving the removal efficiency of heavy oil stains on the lower surface of the aluminum foil 5.

[0027] S3, after the oil is sucked into the guide cavity, the mixture is discharged from both ends of the guide cavity into the degreasing tank 1 under the drive of the rotating fan blade 14. Since there is no aluminum foil 5 blocking the two ends of the guide cavity, the oil quickly floats to the surface of the liquid, making it easy to be removed by existing devices such as the oil skimmer. This avoids secondary pollution caused by the accumulation of oil under the aluminum foil 5. The rotation of the fan blade 14 quickly discharges the sucked oil mixture from both ends of the guide cavity, avoiding the accumulation and secondary pollution of the removed oil under the aluminum foil 5, increasing the oil floating speed, and facilitating subsequent oil treatment.

[0028] Processes S1 and S2 are a synergistic enhancement process. Vibration allows the degreasing solution to penetrate and loosen heavy oil stains, providing pretreatment for physical removal and facilitating subsequent scraping and suction of the oil stains, thereby improving the removal efficiency of heavy oil stains on the lower surface of aluminum foil 5.

[0029] To improve the efficiency of oil sludge being sucked in through the guide hole 12, the guide cavity consists of a truncated conical guide cavity 15 and a cylindrical guide cavity 16. The two ends of the cylindrical guide cavity 16 are respectively connected to the small-diameter ends of the two truncated conical guide cavities 15. With the increase of the discharge port diameter, the suction force at the guide hole 12 is enhanced. The rotating shaft 7 can be driven by the friction of the aluminum foil 5 or by an external power source. These driving methods can be adjusted according to actual needs and are all existing technologies. The oil skimmer and other devices are also existing technologies, so they are not described in detail in the instruction manual.

[0030] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
