[0002] In the field of card printing, with the continuous growth of information and personalization needs, the application scenarios of cards (such as identity cards, membership cards, game cards, etc.) are becoming increasingly widespread, placing higher demands on the quality, efficiency, and personalization of card printing. DOD inkjet printing technology, due to its advantages such as flexible printing, high-resolution printing capability, and adaptability to printing on various card materials, has been widely applied and promoted in this field.

[0003] However, existing DOD inkjet printers have significant and urgent shortcomings when printing cards. Firstly, during the inkjet process, ink is susceptible to splashing or spreading due to factors such as inkjet pressure and airflow in the printing environment, resulting in ink stains on the sides of the card. This not only damages the card's appearance and visual appeal but may also interfere with subsequent card identification and usage functions, reducing card quality. Secondly, after printing one card, ink residue inevitably remains at the printing station. If this residue is not removed promptly and effectively, it is highly likely to contaminate the next card, causing ink smudges, blurred prints, and other problems. This severely reduces the yield rate of printed products, increases the scrap rate in the production process, causes numerous inconveniences for enterprises, and raises production costs. Utility Model Content

[0021] See Figures 1-4 The present invention relates to a card DOD inkjet printing device, comprising a print base 1 and a card vertical conveying device 4 disposed below the print base 1. The print base 1 has a card inlet channel, a card inlet below the card inlet channel, and a printing port above the card inlet channel for engaging with the card. The card vertical conveying device 4 is used to move the card from the card inlet of the print base 1 to the printing port, and to ensure that the upper surface of the card to be printed is flush with the upper surface of the print base 1, while the outer surface is in contact with the inner wall of the print base 1 (e.g., ...). Figure 4 As shown, where number 5 is the card), this ensures that ink will not adhere to the sides of the card or the printing station during the inkjet printing process, thereby ensuring the pass rate of subsequent cards.

[0022] See Figures 1-4 The size of the card inlet is larger than the size of the printing inlet, making the card inlet channel gradually smaller from bottom to top, thus enabling the card to be guided and positioned.
