The invention discloses a raw material slicing mechanism for battery shell production. The raw material slicing mechanism comprises a bearing table and an upper knife edge installing base. A first positioning rod is arranged on the outer side of the upper surface of the bearing table, and a first spring is arranged on the outer side of the first positioning rod. A falling barrel is arranged at themiddle portion of the bearing table through the arrangement of a circular hole. A fixing base is arranged on the upper surface of the bearing table and the outer side of the falling barrel. A bolt isarranged on the outer side of the fixing base through the arrangement of a groove. The lower end of the bolt is connected and fixed to the outer side of the bearing table. A second positioning rod isarranged on the outer side of the upper surface of the fixing base, and a movable pressing plate is arranged above the second positioning rod. A circular through hole is formed in the middle portionof the movable pressing plate, the upper knife edge installing base is arranged above the movable pressing plate, a material cutting column is arranged at the center position of the lower surface of the upper knife edge installing base, and the lower end of the material cutting column penetrates the circular through hole and makes contact with the upper end of the falling barrel. The raw materialslicing mechanism can rapidly tailor the raw material.
