Description

Technical Field

[0001] The utility model relates to the field of removing emulsion from the surface of steel strips, and more specifically to a device for treating residual emulsion on the surface of steel strips after rolling by a 20-roller rolling mill. Background Art

[0002] When rolling steel strip, rolling mills typically use emulsions to cool and lubricate the metal surface to reduce friction and wear, and improve rolling efficiency and product quality. However, some emulsion may remain on the strip surface after rolling.

[0003] The residual emulsion needs to be removed, otherwise it will remain on the surface of the strip and cause the strip to rust. The emulsion can be removed by washing with water, and then the strip can be dried after washing.

[0004] However, since the strip steel is in coiled state after rolling, the cleaning and drying process requires the coil to be rolled up after it has just been rolled out. On the one hand, this requires a larger working space, and on the other hand, the operation must be fast, otherwise the construction period will be delayed. There are many overall restrictions and the operation is more difficult. Utility Model Content

[0013] 3. Beneficial effects

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) In the present invention, a winding roller is sleeved on each of the two columns. One of the winding rollers holds the strip with emulsion, and the other is used to pull the strip for winding. This results in a stretched strip between the two. Cleaning rollers are provided on both sides of the stretched strip through mounting brackets. In this way, during the winding process, the strip passes through these cleaning rollers and is wiped to remove the emulsion. This process is more convenient and faster than the existing water washing and drying method.

[0016] (2) In the present invention, a quick-release mechanism is provided between the upper horizontal plate and the vertical plate in the mounting frame. Under the action of this quick-release mechanism, the two can be separated. In this way, the upper horizontal plate can be removed and the cleaning roller can be replaced. The cleaning roller can be easily replaced to avoid the cleaning roller being too dirty and unable to provide a wiping effect. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] The present embodiment provides a device for treating residual emulsion on the surface of steel strip after rolling by a 20-roll mill. Figure 1 、 Figure 2 and Figure 3 As shown, it includes a winding component and a cleaning component. The winding component includes a base plate 1, two bearing seats 2 are symmetrically installed inside the upper end of the base plate 1, and the bearing seats 2 are connected to the columns 3. The outer peripheral side of the columns 3 can be tightly inserted into the winding roller 4. One of the two winding rollers 4 is used to release the strip steel, and the other is used to take up the strip steel. A rotating mechanism is also provided in the base plate 1 for driving the column 3 that releases the strip steel to rotate. The rotating mechanism includes a servo motor installed on the base plate 1, and the output shaft of the servo motor and the outer peripheral side of the corresponding column 3 are fixedly sleeved with gears that are meshed with each other and located below the winding roller 4. Only the column 3 to which the initially empty winding roller 4 is inserted needs to rotate, which will drive the strip steel to be transferred from the other winding roller 4, separating the two by a distance, so that the strip steel can be stretched for a certain distance to facilitate the operation of the following cleaning component.

[0027] The cleaning assembly includes a mounting frame 5 mounted on the upper end of the base plate 1 through a bracket. The mounting frame 5 is composed of two upper and lower horizontal plates and a vertical plate to form a C-shaped structure. The stretched strip steel passes through the C-shaped opening. The mounting frame 5 is rotated in the opening to engage with a plurality of cleaning rollers 6 arranged on both sides of the stretched strip steel. The outer end of the cleaning roller 6 is provided with a scraping strip 13 located inside the mounting frame 5. The outer end of the scraping strip 13 is provided with a guide hole 14, such as Figure 4 As shown, the cleaning roller 6 comprises a roller body 601, a first cylinder 602, and a second cylinder 603, each of decreasing diameters. The mounting frame 5 has a horizontal plate with a large hole 8 on the inside, matching the diameter of the first cylinder 602, and a small hole 9 on the outside, matching the diameter of the second cylinder 603. The large hole 8 and the small hole 9 are interconnected, with the depth of the large hole 8 being less than the length of the first cylinder 602, and the depth of the small hole 9 being less than the length of the second cylinder 603. The cleaning roller 6 is then engaged and rotatably connected between the upper and lower horizontal plates.

[0028] During the winding process, the strip passes through these cleaning rollers 6 and is wiped to remove the emulsion. Figure 5 As shown, vertical scrapers 10 can be provided on both sides of the stretched strip in front of the mounting frame 5. The inner side structure of the scraper 10 forms a V shape, and the mounting bracket 11 on the scraper 10 is connected to the bottom plate 1; a collecting bucket 12 is also placed on the upper end of the bottom plate 1, which is located directly below the two scrapers 10. The scraper 10 first scrapes off most of the emulsion on the surface of the strip, and flows downward into the collecting bucket 12 through the inner guide of the V shape, and then is wiped by multiple cleaning rollers 6 to achieve a deeper cleaning effect. A scraping bar located inside the mounting frame 5 is provided at the outer end of the cleaning roller 6, and the scraping bar can scrape off the emulsion adsorbed on the surface of the cleaning roller 6, as shown in FIG. Figure 6 As shown, the scraping bar guides the scraped emulsion through the guide holes inside it to prevent the emulsion from being retained on the surface of the scraping bar and affecting the cleaning effect of the cleaning roller 6.

[0029] A quick release mechanism 7 is provided between the upper horizontal plate and the vertical plate in the mounting frame 5 so that the horizontal plate can be separated from the vertical plate. Figure 4 As shown, the quick-release mechanism 7 includes a through hole 701 extending through the vertical plate and a vertical slot 702 extending vertically and communicating with the through hole 701, the inner side of the horizontal plate is connected to a stud 703 passing through the through hole 701, and a nut 704 is screwed on the outer periphery of the stud 703. After the nut 704 is loosened, the upper horizontal plate can be removed from the top and separated from the vertical plate, and the cleaning roller 6 can be removed from the top for replacement. In addition, it is best to set a spring washer connected to the outer periphery of the stud 703 between the nut 704 and the vertical plate, or replace the spring washer and nut 704 with a locking nut. Because the upper side of the vertical slot 702 is open, the nut 704 must be locked to prevent the upper horizontal plate from loosening.

[0030] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
