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.

The utility model provides a kind of three-dimensional compression bag 1, 4, comprising: sealed cavity: by top layer 51, 61, bottom layer 52, 62 and peripheral surface layer 53, or symmetrical side layer 63A, 63B are enclosed and sealed connection formation;Wherein, the peripheral surface layer 53 is sequentially arranged between the top layer 51 and the bottom layer 52 around;Or the side layer 63A, 63B is symmetrically distributed in the top layer 61 and the bottom layer 62 two sides, the top layer 61 extends to the bottom layer 62 around connection;Peripheral surface layer 53 in the utility model is sequentially constituted with a surface layer material, so when sealing assembly is arranged in peripheral surface layer 53, air-tight zipper 2 can be arranged in at least two sides, so that air compression bag opening is more open, and it is convenient for user to take and place article.

This application provides a folding buffer tray, including a top surface with an opening for receiving, and two side surfaces, a connecting surface, a supporting surface, and a snap-fit ​​surface connected sequentially on opposite sides of the top surface. A supporting surface is located on the side of the side surface away from the connecting surface. The snap-fit ​​surface has a first notch, and the supporting surface has a second notch. When folding the cardboard, the top surface, the side surface on one side of the top surface, and the supporting surface form a "U"-shaped frame. The snap-fit ​​surfaces fold towards the bottom of the "U"-shaped frame, the two snap-fit ​​surfaces overlap, and the first notch of the snap-fit ​​surface interlocks with the second notch of the supporting surface. The "U"-shaped frames formed on the two opposite sides of the top surface together constitute a cavity for receiving the bottle. The folding and enclosing mechanism using the side surfaces, connecting surface, supporting surface, and snap-fit ​​surface allows for fast folding; the interlocking of the first notch of the snap-fit ​​surface with the second notch of the supporting surface improves the stability of the bottle. This folding buffer tray is simple to fold, uses less material, and reduces costs.
