Description

Technical Field

[0001] The utility model relates to the technical field of leveling machines, and more specifically, to a leveling machine used for the production of cold-rolled strip steel. Background Art

[0002] A flattening machine is a device used to adjust the surface shape and flatness of metal plates, strips or wires. It is usually used to remove bends, twists or wrinkles on metal materials to achieve the required flatness and surface quality. This equipment plays an important role in metal processing and manufacturing, ensuring the quality and precision of the final product. In the production process of cold-rolled strip steel, a flattening machine is generally used to flatten it.

[0003] After searching, a Chinese patent with publication number CN211839629U discloses a strip leveling machine. In view of the need to level the strip before cutting in the prior art, leveling is to use a strip leveling machine to flatten the curvature of the strip and the protrusions on the surface of the strip. The existing strip leveling machine uses two rollers, and the two rollers are mostly fixed and cannot be adjusted. Strips of different thicknesses cannot be processed, which makes its application range narrow. The strip is passed through a first roller and a second roller, and then a reduction motor is started. The reduction motor drives the second roller to rotate and the strip is leveled. When strips of different thicknesses need to be leveled, the height of the first roller in the vertical direction is adjusted by an adjusting mechanism, so that the distance between the first roller and the second roller is suitable for the thickness of the strip, thereby being able to process strips of different thicknesses and having a wide range of applications.

[0004] During the use of the leveling machine, lubricating oil and emulsion are needed to reduce friction and serve as cooling materials. Lubricating oil and emulsion will remain on the surface of the strip after leveling. It is inconvenient to clean the residual lubricating oil and emulsion. At the same time, some existing technologies only blow the surface, and the cleaning effect is not good. Utility Model Content

[0014] Technical effects and advantages of the utility model:

The number of ventilation boxes 4 is set to two, one of the ventilation boxes 4 is fixedly connected to the fixed box 3 at both ends, and the other ventilation box 4 is slidably connected to the fixed box 3, so as to facilitate the adjustment of the distance between the two ventilation boxes 4.

[0028] As attached Figure 1 , 2 As shown in , 3 and 6, support frames 16 are fixedly installed on both sides of the bottom of the leveling machine platform 1, and the number of the air jet pipes 7 is set to be multiple to improve the purging effect.

[0030] Working principle of the utility model: During use, a flattening machine for cold-rolled strip production provided by the utility model first passes through multiple pairs of flattening rollers 2 for flattening. After flattening, lubricating oil and emulsion are likely to remain on the cold-rolled strip. During use, when the cold-rolled strip moves, it passes between two rubber scrapers 5, and then the lubricating oil and emulsion on the cold-rolled strip are scraped off by the rubber scrapers 5. At the same time, by starting the exhaust fan 6, the exhaust fan 6 draws outside air into the ventilation box 4, and then sprays it out through multiple jet pipes 7 connected to the ventilation box 4, so as to further blow and remove the residual liquid and dust on the cold-rolled strip. At the same time, when adjusting according to the thickness of the cold-rolled strip, by starting the motor 9, the motor 9 drives the threaded rod 10 at its output end to rotate. At the same time, due to the threaded connection between the threaded rod 10 and the threaded sleeve 11, the threaded sleeve 11 is driven to move, thereby driving one of the ventilation boxes 4 to move, thereby adjusting the distance between the two rubber scrapers 5.
