The invention provides a device for putting and arranging paper money, and belongs to the technical field of paper money arranging. The device for putting and arranging paper money comprises an abutting mechanism, and an arranging-flapping mechanism. According to the device for putting and arranging the paper money provided by the invention, a large drive air cylinder and a position regulating air cylinder on an abutting main body are regulated according to an actual dimension of to-be-arranged paper money to determine an arranging space for the paper money; after the paper money is put in, two sides of the paper money abut against two right-angled end surfaces of a datum backup plate, so that preliminary arranging of the paper money is realized; after the paper money is preliminarily arranged, the arranging-flapping mechanism is started, so that an arranging-flapping air cylinder drives an extruding plate to flap the to-be-arranged paper money; after last-time flapping is ended, the extruding plate continuously abuts against the paper money, so that the paper money is kept in order in a bundling process; after paper money bundling is completed, the extruding plate is driven by the arranging-flapping air cylinder to recycle, so that a working process is completed once; and then, an operating process is circulated, so that quick arranging of the paper money is realized, and therefore, paper money arranging efficiency is improved, and arranging burden is relieved.
