[0002] A pad printer is a device used to transfer images or text from a printing or offset printing plate to a surface. Pad printing technology is widely used in industrial production, particularly when high-quality printing is required on objects of various shapes or materials.

[0003] The existing pad printing machine is provided with an inking oil pan and a scraper. The inking oil pan is used to apply printing ink to the surface of the engraving plate, and then the pad printing head is switched. When switching, the inking oil pan drives the scraper to scrape off excess ink on the surface of the engraving plate, leaving only the ink in the pattern grooves on the engraving plate. The ink in the grooves is then printed onto the workpiece by the pad printing head. However, in this method, when the inking oil pan drives the scraper, the scraper can only scrape off the excess ink on the engraving plate once, and often cannot scrape it cleanly, resulting in ink spots in the next printing.

[0004] Therefore, we propose a pad printing machine for automotive interior covering leather to solve the above problems. Utility Model Content
