Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and in particular to an improvement of a digital printing machine. Background Art

[0002] In digital printing, the fabric is laid on a belt, which moves forward and under the printhead. The belt pauses, and the printhead reciprocates. After printing a specific point, the belt moves forward again, pauses, and the printhead continues printing the next point, repeating this cycle until the entire pattern is printed. Currently, most digital printers on the market use dry-printing and scanning technology, which involves complex process steps. Conventional scanning printing methods require pauses in the printing belt, while wet printing methods leave indentations when pauses occur. Utility Model Content

[0030] In one embodiment, the ink scraping mechanism 111 is composed of a positioning base plate and a rotating mechanism, and a fixing rod and an adjusting mechanism are fixed on the positioning base plate.

[0031] Working principle:

[0032] The guide belt 108 moves forward continuously, and the fabric is fed into the fabric from the pressing roller 101, passes through the sizing section 102 for printing and pressing 104, and then comes out of the fabric to enter the next process. The printing carriage 105 needs to remain relatively stationary with the guide belt while printing, and move forward together after printing one layer. After printing one layer, it quickly moves backward to print the next layer. The sizing section 102 for pressing and penetrating is stationary relative to the frame 107.
