Abstract

The utility model discloses an efficient automatic corrugated paper cutting and creasing device, which relates to the technical field of corrugated paper processing and comprises a linear motor, a lifting device is fixedly mounted on a moving part of the linear motor, a rotating device is arranged at an output end of the lifting device, an adjusting device is fixedly mounted on a rotating shaft part of the rotating device, and the adjusting device is arranged on the rotating shaft part of the rotating device. Adjusting blocks are symmetrically arranged at the lower end of the adjusting device, creasing wheels are fixedly installed at the lower ends of the adjusting blocks through elastic mechanisms, connecting frames are fixedly installed on the outer sides of the elastic mechanisms, electric push rods are fixedly installed at the upper ends of the connecting frames, and the output ends of the electric push rods movably penetrate through the connecting frames and are fixedly provided with tool aprons. By the adoption of the structure, the pull rod is pulled through the pull handle, the movable plate connected with the pull rod drives the clamping block to be separated from the clamping hole in the cutting knife, then the cutting knife can be directly pulled out of the inserting groove of the knife holder, and therefore the cutting knife can be rapidly disassembled, assembled, replaced and used conveniently.
