Material carrying conveyor in copper-aluminum composite bar casting system

The utility model discloses a material carrying conveyor in a copper-aluminum composite bar casting system. When a copper-aluminum composite bar is needed to be carried, a moving seat forwards slides on a machine seat in the axial direction of a transmission roller, a driving structure drives a connecting element to upwards rotate, a support plate descends, and the copper-aluminum composite bar is carried, then, the moving seat backwards slides to reset, the supporting plate descends, the copper-aluminum composite bar is placed on a plurality of transmission rollers to be conveyed, in the descending and ascending process of the copper-aluminum composite bar, a first chain wheel fixed on a fixed element and a second chain wheel fixed on the supporting plate are in mutual transmission through chains, a part on the support plate for carrying the copper-aluminum composite bar is ensured that inclination in the descending and ascending process of the supporting plate can not be generated, so the supporting plate c
