The present invention discloses an energy-saving folding roller and a paper folding machine using the same. The folding roller comprises a folding roller body, in which at least two paper folding air suction channels and a paper cutting air suction channel are arranged, and a core shaft is also included. The folding roller body is sleeved on the outer periphery of the core shaft and can rotate around the core shaft. The core shaft is a hollow tube body with a hollow channel, and at least one end of the hollow channel is connected to an external device. At least one first vent hole and a second vent hole connected to the hollow channel are opened along the length direction of the core shaft surface. The first vent hole cooperates with one of the paper folding air suction channel and the paper cutting air suction channel, and the second vent hole cooperates with two of the paper folding air suction channel and the paper cutting air suction channel. The core shaft is a hollow tube body with a hollow channel. Under the action of the external device, the air in the air suction channel can be quickly drawn out from the vent holes opened along the length direction of the core shaft surface to the hollow channel, which greatly reduces the energy consumption of the external air extraction device and is energy-saving and environmentally friendly.
