Thin material shearing machine

The utility model discloses a thin material shearing machine which comprises feeding rolls, guiding rolls and a shear knife, and further comprises a pushing mechanism, wherein a thin material is arranged on the feeding rolls; a thin material passage, through which the thin material can pass, is formed between the guiding rolls; the shear knife comprises an upper blade and a lower blade; a shearing passage is formed between the upper and lower blades, and over against the thin material passage; the shearing passage and the thin material passage form a conveying passage; the pushing mechanism comprises moving platforms and a first driving mechanism; the moving platforms comprise flat plates which are horizontally arranged, face the shearing passage and are arranged in the conveying passage; the first driving mechanism drives the moving platforms to perform linear reciprocating movement; the flat plates are driven to move in the conveying passage in a reciprocating manner, and can pass through the shearing passage; the thin material is guided by the horizontally arranged flat plates during the conveying process, so that the whole tension of the thin material in the conveying process is uniform, and the thin material is effectively prevented from warping or bending during the conveying process, and further effectively prevented from being scratched by the shear knife.
