Paper folding machine

Abstract

The invention discloses a paper folding machine which comprises a rack, a paper folding mechanism and a driving device. The paper folding mechanism comprises an upper paper folding device (1), a lower paper folding device (2) and a synchronous belt wheel device, the upper paper folding device (1) comprises an upper paper folding baseplate (15), an upper paper pressing cam (102) and an upper paper pushing cam (101), the lower paper folding device (2) comprises a lower paper folding baseplate (25), a lower paper pressing cam (202) and a lower paper pushing cam (201), the synchronous belt wheel device comprises an upper synchronous belt wheel (30), a lower synchronous belt wheel (31) and a synchronous belt (32), two cams in the upper synchronous belt wheel (30) and the upper paper folding device (1) are coaxially and fixedly connected, two cams in the lower synchronous belt wheel (31) and the lower paper folding device (2) are coaxially and fixedly connected, and the upper synchronous belt wheel (30) and the lower synchronous belt wheel (31) is connected with the driving device. The paper folding machine can automatically fold paper to be in the shape of an accordion blade in positive and negative directions.

Description

technical field [0001] The invention relates to an origami device for craft or filter element origami, in particular to an origami machine that folds paper into an accordion blade shape by repeatedly folding back and forth in forward and reverse directions. Background technique [0002] The working principle of the existing origami machine generally includes the combination of cylinder origami, crank origami, gear origami, etc. The cylinder origami adopts a combination of multiple cylinders for one action. Since there is no self-locking function between the cylinders, the action sequence is determined by sensors, the mechanism is complex, and the origami is complicated. The accuracy is not high; the origami action of the crank origami mechanism is a curve, it is difficult to form a rectangular motion trajectory, and it is difficult to fold the paper into an equilateral shape; the gear origami can only leave shallow creases on the paper, and cannot be done after the origam...

Problems solved by technology

[0002] The working principles of existing origami machines generally include combined cylinder origami, crank origami, gear origami, etc. Cylinder origami uses a combination of multiple cylinders for one action. Since there is no self-locking function between the cylinders, the sequence of actions is determined by sensors. The mechanism is complex and the origami The precision is not high; the origami action of the crank origami mechanism is a curve, it is difficult to form a rectangular motion track, and it is difficult to fold the paper into an equilateral shape; the gear origami can only leave shallow creases on the paper, and cannot Harvest paper into accordion leaf shape

These origami machines generally can only fold the paper in half once or multiple times, and cannot repeatedly fold the paper into an accordion leaf shape.
