Description

Technical Field

[0001] The present invention relates to the field of automated office work, and particularly to a punching machine for automated office work and a control method for a punching machine for automated office work. Background Art

[0002] The original design intention of a punching machine is to punch required holes on paper-based office documents such as format paper or thin paper sheets. In daily office work, paper is essential, and punching and binding of paper is often faced by clerks engaged in related work such as accounting and human resources. Common punching machines use manual operation for punching. Although a labor-saving design is made using the lever principle, in actual use, it is usually necessary to punch holes with different apertures on office documents, or to punch a row of equally spaced holes on an office document, while a manual punching machine cannot meet the above requirements.

[0003] The patent application document with the application number 201721919515.7 discloses a punching machine. By optimizing the mechanical structure, it can be more labor-saving than a conventional punching machine and has better mechanical transmission performance. However, there is only one type of punching punch with a single aperture in the punching machine, which cannot meet the requirement of punching with multiple apertures. Moreover, when punching in a row, manual operation cannot ensure uniform aperture, is time-consuming and laborious, and does not meet the needs of modern office work.

[0004] The invention patent application document with the application number 201810253866.1 discloses a special punching machine for office supplies. By pressing the handle to drive the punching punch to slide towards the base, because the punch has good mechanical properties, it can complete punching of various types and different thicknesses of office paper, but still cannot meet the requirement of punching with multiple apertures. Moreover, when punching in a row, manual operation cannot ensure uniform aperture, is time-consuming and laborious, and does not meet the needs of modern office work. Summary of the Invention
