With the increasing demand for the quality, production efficiency and personalization of printed matters, higher requirements are put forward for the flexibility, precision and automation degree of the printing equipment.

[0003] The traditional full-rotary flexible printing machine adopts a replaceable cylinder type plate mounting mode, and different plate rollers with the same length need to be replaced for printing different plate lengths. Since different products require a large number of plate rollers to be prepared, the cost is high. The intermittent flexible printing machine does not need to replace the plate cylinder and directly pastes the plate. The paper is printed in a one-in-one-out mode. The plate roller of the intermittent flexible printing machine generally cannot be quickly removed. When the plate roller cannot be quickly removed, it is difficult to ensure the flatness of the pasted plate on the machine. At present, the intermittent full-rotary dual-purpose printing machine on the market mainly adopts a one-color two-color printing structure. The intermittent structure adopts an inverted pull swing rod structure. The paper path is long, which affects the printing effect when multiple groups are used. Moreover, the equipment cost is high. The unwinding and winding unit of the printing machine does not have an automatic threading function. When a new material is replaced, the operator must manually thread the front end of the material through a large number of guide rollers, tension rollers, correctors and printing units, and the whole process is complicated, time-consuming and labor-intensive.
