The invention relates to a corner wrapping machine for a honeycomb paperboard. The corner wrapping machine comprises a corner wrapping machine body support and has the characteristics that a flattening mechanism is arranged at the feeding end of the corner wrapping machine body support, a profiling component is arranged at the upper end of the flattening mechanism, a pushing and pressing component is arranged at the top of the working end surface of the profiling component, and a transmission component is arranged at the discharge end of the corner wrapping machine body support. Therefore, depending on the match of the flattening mechanism, the profiling component and the pushing and pressing component, the whole process of paper feeding and corner wrapping is safe and reliable. Simultaneously, due to the existence of a material lifter, the complicated step that an operator bends down to take materials is avoided, and the production efficiency is improved.
