The utility model relates to the technical field of newspaper and periodical manufacturing, in particular to a multipurpose folding machine for newspapers and periodicals, which not only can be used for stacking multiple layers of newspapers and periodicals and conveniently folding multiple groups of newspapers and periodicals once, but also can be used for conveniently folding newspapers and periodicals with different sizes, so that the applicability of the device is improved. Comprising a conveying mechanism; the newspaper and periodical pressing device further comprises a traction mechanism, a clamping mechanism, a lifting mechanism, a pressing mechanism and two sets of extrusion mechanisms, the traction mechanism is installed on the conveying mechanism and drives the clamping mechanism to move, the clamping mechanism is installed on the traction mechanism to clamp newspapers and periodicals, and the lifting mechanism is installed on the conveying mechanism and drives the pressing mechanism to lift. The pressing mechanism is installed on the lifting mechanism and presses the newspapers and periodicals, and the two squeezing mechanisms are installed on the conveying mechanism and press the newspapers and periodicals.

The utility model discloses a curtain type safety air bag bag with high inflation reliability. The curtain type safety air bag bag with high inflation reliability comprises an upper air bag piece and a lower air bag piece, the upper air bag piece and the lower air bag piece are stitched to form an air bag cavity, and the air bag cavity is provided with an inflation port. The curtain type safety air bag bag comprises a gas guide reinforcing piece arranged at the inflation port, the gas guide reinforcing piece comprises two first reinforcing pieces and two second reinforcing pieces, the two first reinforcing pieces and the two second reinforcing pieces are located between the upper air bag piece and the lower air bag piece, and the two second reinforcing pieces are located outside the two first reinforcing pieces. The first reinforcing piece has an overlapping part overlapping with the second reinforcing piece and a gas nozzle part extending beyond the second reinforcing piece, the two first reinforcing pieces and the two second reinforcing pieces are stitched at the partial edges of the overlapping part and are provided with gas distribution ports, and the two first reinforcing pieces are respectively stitched with the upper air bag piece and the lower air bag piece at the edges of the gas nozzle part.

The utility model discloses a folding mechanism of a film cutting and folding machine, and relates to the technical field of film processing, the folding mechanism of the film cutting and folding machine comprises a film cutting machine, the end portion of the film cutting machine is fixedly connected with a supporting table, and rectangular sliding grooves are formed in the supporting table in a rectangular array mode; thin film edge guide frames are symmetrically and movably connected to the upper portion of the supporting table, and the end, close to the thin film cutting machine, of each thin film edge guide frame is movably connected with an edge extrusion wheel. The film edge guide frame comprises side baffles, and a spiral guide face is integrally arranged on the side face of each side baffle. According to the film folding device, downward pressure is applied to the movable sliding block through the elasticity of the compression spring, so that the edge of a folded film is squeezed, the squeezing roller at the bottom of the movable sliding block guides the edge of the film, the phenomenon that the edge of the film rebounds after being folded is prevented, and the positioning column on the movable sliding block is in sliding fit with the circular groove, so that the film can be conveniently folded. And the limiting effect can be achieved.
