The invention relates to a corrugating machine capable of quickly changing rolls, belonging to the technical field of machine packaging. The corrugating machine of the invention comprises a rack provided with a compression roller mechanism and a sizing mechanism; the rack is provided with at least two pin roller structures and devices, wherein the pin roller structures can press corrugated paper of different corrugated shapes, and the devices are used for respectively moving the pin roller structures to the working position. Due to the adoption of the structure, the invention can finish exchanging corrugated rollers of different corrugated shapes in five minutes without manual disassembly, and can finish the task by the simple operation of a touch screen on an operation table of a PLC control system; thus, the corrugating machine of the invention is a necessary device which can effectively improve full line efficiency under the environment of corrugated paper boards with small batch and various specifications.
