Description

Technical Field

[0001] The utility model belongs to the technical field of small office equipment, and in particular relates to an accounting bill punching device. Background Art

[0002] All accounting documents must be bound when they are archived. Since the documents are of different sizes and styles, holes are usually punched on the edges and then fixed with ropes or buckles to avoid them being tangled or lost when checked later.

[0003] At present, there are generally two ways to punch bills. One is to use a large needle or awl to directly pierce the bill by hand and then thread it to fix it; the other is to use a small device to press and punch the bill. Although the above structure is simple, it is not labor-saving enough, resulting in insufficient penetration thickness. There are also electric and hot-melt types on the market, which require additional energy consumption, have more parts, are easy to break, and have a short service life.

[0004] In addition, some bills are torn from bound books and have uneven surfaces, and some bills have binding holes. In this case, the punching position needs to extend inward, but the punching device in the prior art has not yet been set up for this adjustment.

[0005] Application number: 2023205667001, discloses a convenient alignment punching device for punching bills, belongs to the technical field of punchers, comprises a fixed base, a placement slot for placing bills is provided on the top surface of the fixed base, an alignment plate is movably provided inside the placement slot; an adjustment mechanism is provided on the fixed base, the adjustment mechanism is connected to the alignment plate, and can drive the alignment plate to move left and right; first beams are provided at both ends of the fixed base through a support plate, a second beam that can move forward and backward and is located above the placement slot is provided between the two first beams, and a punching mechanism that can move left and right is provided on the second beam. The convenient alignment punching device for punching bills described in the utility model has a reasonable design, ingenious structure, flexible punching operation, good bill alignment effect, can effectively avoid the phenomenon of bill offset during punching, can greatly improve work efficiency, and is suitable for popularization and use.

[0006] In the above scheme, an alignment plate is provided, and the alignment effect of the bill is better, but the effect of the pressing force is poor and the penetration force is limited.

[0007] Application No.: 2023202091870 discloses a bill flattening and punching device, which includes: a base, a storage groove is provided at the bottom of the base, a rotating shaft is rotatably connected to the inner wall of the storage groove, and a "冂"-shaped rotating frame is fixedly connected to the circumferential surface of the rotating shaft.

[0030] The punching plate is provided with a plurality of groups of insertion holes 2 , and the back of the punching head 4 is provided with a threaded rod 42 , which passes upward from the bottom of the insertion hole and is fixed by a bolt 43 .

[0031] according to Figure 4 The pressing head 4 is in a pointed column or tubular shape. The pressing head 4 is composed of a threaded rod 42, an annular platform 41 and a pressing head 40 from top to bottom. When the pressing head 40 is tubular, the bottom ring is arc-shaped, which is convenient for piercing.

[0032] The base is provided with two parallel slide rails 13; the slide rails are provided with a slidably connected positioning plate 12, which is perpendicular to and fits the base 10. A slider is provided below the positioning plate 12 and penetrates into the slide rail 13. A certain damping is provided between the slider and the slide rail, so that the slider can maintain stability. After a thrust is applied, the slider can slide forward and backward and remain parallel to the punching plate 3.

[0033] A pressing plate 16 is provided below the punching plate 3; the pressing plate is telescopically connected to the punching plate via a spring 17; and a reserved hole corresponding to the punching head is provided on the pressing plate.

[0034] Anti-skid pads 9 are arranged at the four corners below the base. The anti-skid pads 9 have the functions of anti-skid and allowing a gap to be created at the bottom to clean up paper scraps.
