AI Technical Summary

Technical Problem

The existing double-cut indenter has a complex structure and is difficult to achieve a compact volume. At the same time, when the forward and reverse indentation processing, the paper positioning error and deformation affect the error of the indentation line distance.

Method used

A double-cutting indentation structure is designed, including a first conveying rubber roller group and a second conveying rubber roller group. The two indentation units are arranged adjacently in parallel, and the opening and closing of the upper and lower cutting components is driven by an electric motor to realize forward and reverse indentation processing.

Benefits of technology

A compact structural design is achieved, reducing volume, improving paper positioning accuracy and stability, avoiding the need to set up an additional conveying roller set, and simplifying the structure.
