Description

Technical Field

[0001] This utility model relates to the technical field of degreasing devices, specifically a degreasing device for the surface of strip material from an aluminum foil rolling mill. Background Technology

[0002] The degreasing device for aluminum foil rolling mill strip is a device used to remove oil stains from the surface of aluminum foil rolling mill strip. This device is suitable for the production process of aluminum foil rolling mill strip, and can effectively prevent oil stains from splashing onto the strip surface, eliminate oil stain defects on the strip surface, improve product quality, and facilitate subsequent processes.

[0003] An investigation revealed a Chinese utility model patent (publication number: CN221269306U) disclosing an oil removal device for the strip surface of an aluminum foil rolling mill. The device includes a cover plate installed on the upper side of the support rollers on the mill stand and a splash guard installed at the outlet of the work rollers. Both ends of the cover plate have collection grooves, and the bottom of the splash guard has a guide groove. An adjustable-angle fan-shaped nozzle is located in the middle of the lower side of the splash guard. The mill stand is equipped with a roller cleaner for cleaning the support rollers. This oil removal device for the strip surface of an aluminum foil rolling mill can collect and guide both condensed and splashed oil, preventing oil from splashing onto the upper surface of the strip outlet. It also forms an air curtain at the strip outlet, eliminating oil defects on the strip surface, thereby improving product quality, facilitating subsequent processes, and is easy to use.

[0004] The aforementioned patent removes oil stains from the board surface by using a support roller and its outer anti-splash felt, in conjunction with a cleaning roller. However, the non-replaceable structure of the support roller means that after prolonged use, the anti-splash felt on the surface of the support roller may wear down, resulting in incomplete removal of oil stains. Consequently, as the support roller rotates, the oil stains are transferred back to the board surface, reducing the oil removal effect. Furthermore, the single-structure design requires machine shutdown when replacing the support roller, further reducing the continuity of the device's operation and its efficiency.

[0005] Therefore, this utility model provides an oil removal device for the surface of aluminum foil rolling mill strip to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5As shown, this utility model provides an oil removal device for the strip surface of an aluminum foil rolling mill, including a support assembly 1. The support assembly 1 includes a positioning frame 11, with a support frame 12 and a first cylinder 13 fixedly connected to the inner wall of the positioning frame 11. An adjusting frame 14 is fixedly connected to the bottom of the first cylinder 13. Mounting frames 15 are fixedly connected to the outer walls of both the support frame 12 and the adjusting frame 14. Two sets of oil removal assemblies 2 are also included. Each oil removal assembly 2 includes a main shaft 21, with partitions 23 at both ends of the main shaft 21. Three sets of oil removal rollers 24 are rotatably arranged between the two partitions 23. A servo motor 25 is fixedly connected to one end of the central shaft of each set of oil removal rollers 24. One end of the main shaft 21 is fixed... Connected to a second cylinder 22, two sets of degreasing components 2 are used for degreasing the upper and lower surfaces of the strip. The first cylinder 13 drives the adjusting frame 14 to adjust up and down, which in turn adjusts the height of the upper degreasing component 2. By adjusting the distance between the upper and lower sets of degreasing components 2, it can be adapted to degreasing strips of different thicknesses, further improving the adaptability of the device. At the same time, the multiple degreasing rollers 24 in each set of degreasing components 2 allow for the disassembly and replacement of damaged degreasing rollers 24 during degreasing operations, ensuring the degreasing effect of the degreasing rollers 24 and avoiding the need for the rolling mill to stop.

[0026] Furthermore, the support frame 12 and the adjustment frame 14 are symmetrically distributed inside the positioning frame 11, and the adjustment frame 14 is located above the support frame 12. The adjustment frame 14 can be adjusted up and down by the first cylinder 13. The adjustment frame 14 is driven to move up and down by the control of the first cylinder 13, which in turn drives the upper oil removal component 2 to adjust its height so that it can be used to adapt to strips of different thicknesses.

[0027] Furthermore, the single rotation angle of the second cylinder 22 is 120 degrees. A servo motor 25 is fixedly connected to the outer wall of the partition 23 at the end away from the second cylinder 22. The sum of the lengths of the degreasing roller 24 and the servo motor 25 is less than the length of the support frame 12. The second cylinder 22 is a rotary cylinder, mainly used for the rotation adjustment of the main shaft 21, thereby realizing the rotation adjustment of the degreasing roller 24 at different positions, ensuring that the degreasing roller 24 is in contact with the strip surface after each rotation adjustment.

[0028] Furthermore, each mounting frame 15 is provided with a set corresponding to the support frame 12 and the adjustment frame 14. Each set of mounting frames 15 has two sets, and the two sets of mounting frames 15 are respectively located on both sides of the positioning frame 11. The outer wall of one set of mounting frames 15 is fixedly connected to a third cylinder 3, and the lifting end of the third cylinder 3 is fixedly connected to a first cleaning roller groove 31. The outer wall of the other set of mounting frames 15 is fixedly connected to a fourth cylinder 4, and the lifting end of the fourth cylinder 4 is fixedly connected to a second cleaning roller groove 41. The third cylinder 3 and the fourth cylinder 4 are both linear cylinders, used to pull the first cleaning roller groove 31 and the second cleaning roller groove 41 horizontally. Under the lifting control of the third cylinder 3 and the fourth cylinder 4, the first cleaning roller groove 31 and the second cleaning roller groove 41 are pressed against the outer wall of the degreasing roller 24, thereby cooperating with the rotation of the degreasing roller 24 to scrape off the oil stains on the surface of the degreasing roller 24.

[0029] Furthermore, the ends of the first cleaning roller groove 31 and the second cleaning roller groove 41 near the oil removal roller 24 are both arc-shaped, and the arc-shaped structure abuts against the outer wall of the oil removal roller 24. The inner wall structure of the first cleaning roller groove 31 and the second cleaning roller groove 41 is high in the middle and low on both sides. Both sides of the first cleaning roller groove 31 and the second cleaning roller groove 41 are integrally connected with oil drain pipes, which facilitates the drainage of oil stains collected inside the first cleaning roller groove 31 and the second cleaning roller groove 41, thereby improving the convenience of oil stain collection of the device.

[0030] Working principle: First, the device is installed and positioned. When the strip is conveyed, the oil stains on the surface of the strip are removed by the contact and rotation of the upper and lower oil removal rollers 24. During the rotation of the oil removal rollers 24, the oil stains adhering to the surface of the oil removal rollers 24 can be scraped off by contact with the outer walls of the first cleaning roller groove 31 and the second cleaning roller groove 41, thus ensuring that the oil removal rollers 24 in a clean state can re-contact the surface of the strip. When the oil removal rollers 24 in contact with the strip are damaged, the oil stains may not be completely removed. At this time, the first cleaning roller groove 31 and the second cleaning roller groove 41 are pulled back and the main shaft 21 is rotated. By switching the oil removal rollers 24 in different positions, the damaged oil removal rollers 24 can be replaced, which is convenient for subsequent recycling. This allows for oil removal operation without stopping the machine and improves the efficiency of the device.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
