Seam pressing device

The utility model relates to the technical field of packaging carton production, and discloses a seam pressing device which comprises an operation table, a support is arranged on the side wall of the operation table, and a limiting assembly is arranged on the end face of the top of the operation table. According to the seam pressing device, the fixed buckle and the movable buckle achieve positioning of a paperboard, the situation that the paperboard shifts in the seam pressing process, and consequently an impressing line deviates is avoided, the paperboard is pressed by the pressing strip continuously while the seam pressing wheel conducts seam pressing on the paperboard, the stability of the paperboard in the seam pressing process is further improved, the impressing line deviating phenomenon is prevented, and the production efficiency is improved. When the seam pressing wheel moves, sliding friction between the pressing strip and a paperboard is converted into rolling friction through the rolling wheel, smoo
