The utility model relates to a field material levelling technical field, need be with the material levelling of unevenness originally in the machining process, for example steel wire etc.. In the actual production process, the incoming raw material is irregular in arc shape, a single-section upper-lower double-row leveling working roll is adopted by a common leveling mechanism in the prior art, the purpose of leveling the coiled material is achieved by staggered arrangement of an upper part and a lower part, the arc leveling mechanism can only be suitable for the radian leveling of a single direction of the material, the raw material with irregular arc shape is difficult to level to a preset straightness, the use requirement of a client is met, and the produced product is unqualified. Based on this, the embodiment of the present invention provides a multi-stage leveling mechanism, which aims to solve the above problems.

Specifically, as shown in fig. 1, the multi-stage leveling mechanism comprises a first leveling assembly and a second leveling assembly which are sequentially arranged, wherein the first leveling assembly comprises a first upper working roll 1 which is rotatably arranged on an upper layer and a first lower working roll 2 which is rotatably arranged on a lower layer, and the second leveling assembly comprises a second upper working roll 3 which is rotatably arranged on the upper layer, a second lower working roll 4 which is rotatably arranged on the lower layer and an eccentric roll 5 which is rotatably arranged. Wherein, first upper strata working roll 1, second upper strata working roll 3 all are connected and can go up and down with the sliding pair, and first lower floor's working roll 2, second lower floor's working roll 4 all fixed in position to make raw and other materials such as steel wire can install the working face between upper strata working roll and the lower floor's working roll smoothly and level. The eccentric roller 5 is eccentrically rotatable so that its working surface is offset from the working surface between the second upper and lower working rollers 3 and 4. The arrangement of the rear working rolls of the whole second leveling assembly is changed by the combination of the eccentric roll 5 and the second working rolls, so that the preset correction (angle) effect is achieved.

Specifically, in this embodiment, two first upper working rolls 1 are provided, and three first lower working rolls 2 are provided and distributed in a staggered manner with the first upper working rolls 1; the number of the second upper working rolls 3 is five, the number of the second lower working rolls 4 is four, the second upper working rolls are distributed in a staggered mode with the second upper working rolls 3, and the positions of the eccentric rolls 5 correspond to those of the second lower working rolls 4. Therefore, the first section of working roll adopts an arrangement mode of upper two and lower three, can be used when raw materials are fed and turned up, and can level the raw materials by repeatedly eliminating stress through the working roll. The second section of working roll adopts the arrangement mode of five upper parts and four lower parts, and the curvature correction is carried out on the material leveled by the first section of working roll, so that the material meets the use requirement. And the material can be adjusted to different curvatures and the like in the second section by adjusting the eccentric roller 5, so that special use requirements are met.
