Description

Technical Field

[0001] The invention relates to the field of textile technology, in particular to an improvement of a digital printing machine. Background Art

[0002] In digital printing, the guide belt is the transport mechanism for the fabric to be processed, that is, the fabric to be processed is laid on the guide belt. During the operation of the guide belt, the fabric to be processed moves forward with the guide belt to the bottom of the nozzle, the guide belt stops, and the nozzle reciprocates. After the printing of the node is completed, the guide belt moves forward again and stops, and the nozzle continues to print the next node, and so on and so forth to complete the printing of the entire pattern. At present, most of the digital printing machines on the market are dry scanning type, which has many dry printing process flows. The ordinary scanning printing guide belt will pause, and wet printing will have indentation once it pauses. Summary of the invention
