Description

Technical Field

[0001] The utility model belongs to the technical field of printer device accessories, and particularly relates to an ink absorbing pad. Background Art

[0002] In recent years, large-format printers have been rapidly and widely used in many fields due to their good image quality, short delivery time, and ability to print on a variety of printing materials. After a period of continuous operation, the print head of the printer will experience ink drying and other ink-breaking phenomena. At this time, the print head needs to be cleaned to clear the nozzles inside the print head, ensure smooth ink circulation, and thus achieve high-quality printing effects. However, the ink-absorbing substrates on traditional ink-absorbing pads are mostly installed by screws and elastically reset by springs. Generally, multiple ink-absorbing substrates are installed on an ink-absorbing bottom shell to adapt to the ink-absorbing heads of multiple printers. Therefore, the use of screws for installation is cumbersome, and the use of springs for reset is prone to metal elastic fatigue, which affects the service life. Therefore, it is very important to obtain an ink-absorbing pad that overcomes the above defects. Utility Model Content
