Description

Technical Field

[0001] The utility model relates to the technical field of pad printing machines, in particular to a double-sided automatic pad printing device. Background Art

[0002] Pad printing machine is a kind of printing equipment, which is suitable for plastics, toys, glass, metal, ceramics, electronics, IC seals, etc. Pad printing is an indirect printing technology with a concave rubber head, and has become a major method for printing and decorating the surfaces of various objects.

[0003] At present, a traditional pad printing machine usually includes a frame with an open ink tray on the frame. First, the pattern to be printed is engraved on a steel plate, and then the steel plate is placed in the ink tray. The ink on the ink tray is scraped into the groove engraved on the steel plate by an ink scraping assembly arranged on the frame. Then, the pad printing machine drives the pad printing assembly arranged on the steel plate to move the pad printing assembly to the top of the groove. The pad printing assembly drives the rubber head to move downward to the pattern groove to dip in ink. After dipping in ink, the rubber head moves to the top of a clamping device arranged on the frame for clamping a cosmetic bottle. Finally, the pad printing assembly drives the rubber head to press down on the surface of the cosmetic bottle fixed by the clamping device, so that the pattern can be printed.

[0004] In the above scheme, the clamping device in the prior art can only play the role of fixing the cosmetic bottle. When it is necessary to print patterns on both sides of the cosmetic bottle, the staff needs to manually turn over the cosmetic bottle, which is inefficient and increases the labor intensity of the staff.
