The invention discloses a material stacking device and a material stacker and belongs to the technical field of machining. The material stacking device is arranged on a rack and comprises a magazine clip device. The magazine clip device comprises a magazine clip loading mechanism configured to arrange bars in a layered manner and a material pushing mechanism configured to push the bars arranged inthe layered manner to a material frame to stack the bars. The material stacker comprises the material stacking device. According to the material stacking device, by arranging the magazine clip device, the bars are stacked layer by layer, so that the bars arranged in layers will not be loose in the stacking process while the stacking efficiency is improved. Adjacent bars can be laminated fully, sothat the bars are placed stably in the material frame.
