Functional principle:
This machine adopts pneumatic main force, and the large characters can be adjusted freely, which greatly overcomes the disadvantage of difficult coding for large cardboard boxes, woven bags, and laminated cardboard boxes in the past. This coding machine uses a ribbon instead of ink for printing, which can achieve better printing results. It adopts a special structure for loading, unloading, and changing large characters, which can print on various large packaging materials with clear and difficult to erase printing.
