Description

Technical Field

[0001] The utility model relates to the technical field of office equipment, and more specifically, to a bill punching device. Background Art

[0002] The bill punching device is a kind of office equipment commonly used in the fields of finance, accounting, and file management. It is mainly used to punch holes in bills, vouchers, etc. for binding into books. Existing bill punching devices generally include the following components: a base plate, as the basic part of the machine, supporting the structure of the entire machine; an extrusion assembly, used to flatten the bill for punching; a punching assembly, including a pneumatic or electric punch, for punching holes in the bill. When in use, the bill is placed on the base plate and flattened by the extrusion assembly, and the punching assembly performs the punching operation. As an example, patent CN211440288U discloses a relatively conventional financial bill punching device.

[0003] At present, small bill punching devices generally only have one punch. When multiple holes need to be punched on a bill, the user often needs to repeatedly release the squeezing component on the bill to adjust the bill position, which is not conducive to improving work efficiency, reducing manual labor intensity, and ensuring the accuracy and consistency of punching.

[0004] Therefore, it is necessary to improve the existing bill punching device to solve the above technical problems. Utility Model Content

[0032] This embodiment provides a bill punching device, which can be used in the following specific steps:

[0033] Step 1, bill preparation: lay the bill flat on the placement plate 3, and ensure that the position of the bill is correctly aligned so that the punch 2 can accurately pass through the bill.

[0034] Step 2, pressing the bill: through the pressing assembly, use the first elastic reset member 7 to press the bill on the placement plate 3 to ensure that the bill is stable and motionless during the punching process.

[0035] Step three, adjust the position of the placement plate 3: according to the position where the hole needs to be punched on the bill, operate the first driving assembly to move the placement plate 3 to an appropriate position in the longitudinal direction.

[0036] Step 4, aligning the punch 2: ensure that the punch 2 is aligned with the through hole 4 on the placement plate 3 so that the punch 2 can accurately penetrate the bill.
