Abstract

The invention relates to a punching device, in particular to an accounting bill crease-free automatic flattening and punching device. The technical problem to be solved is to provide an accounting bill crease-free automatic flattening and punching device which can punch three holes at a time, is high in punching efficiency and can clamp and limit accounting bills in the punching process. According to the technical scheme, the crease-free automatic flattening and punching device for the accounting bills comprises a mounting shell, a cover plate, an electric push rod, a descending plate, an annular cutter, a push-pull mechanism and a pressing mechanism, the cover plate covers the top of the mounting shell, the electric push rod is arranged in the middle of the bottom of the cover plate, and the descending plate is arranged at the bottom of a telescopic rod of the electric push rod; and three annular cutters are arranged at the rear part of the descending plate. The telescopic rod of the electric push rod extends to drive the descending plate and the annular cutter to move downwards, and the annular cutter moves downwards to automatically punch accounting bills.

Description

technical field [0001] The invention relates to a punching device, in particular to an automatic flattening and punching device for accounting bills without creases. Background technique [0002] Most of the companies have set up financial departments, and the financial department involves a lot of bills. In order to facilitate the neat collection of bills, the bills are usually punched, and then the bills are sorted together with a ring. [0003] The patent application number is CN201920564348.1 A multi-purpose punching machine for accounting bills, including a base, a hole is opened on the upper surface of the base, and a debris box is provided at the bottom of the hole, and the debris box is clamped with the base. One side of the base is fixedly connected with a first pin, the surface of the first pin is sleeved with a telescopic rod, and the end of the telescopic rod far away from the first pin is socketed with the second pin, and one of the first pins is The side is fi...
