Description

Drying device for printing ink of packaging box

Technical Field

The application relates to a printing stoving technical field especially relates to a drying device is used in printing of packing carton printing ink.

Background

The ink printing of the packing box takes various packing materials as carriers, and the decorative patterns are damaged on the packing box through the ink to protect commodities, beautify the commodities and transmit information. Meanwhile, the packaging printing industry is also modifying the traditional technology, for example, the common solvent ink for printing is replaced by water-based ink, and the water-based ink is also called water-based ink and is recognized as environment-friendly printing ink in the world printing industry. Water-based inks dry more slowly than solvent-based inks, and therefore development of green press drying technology is also needed.

In the related art, after printing, the packaging box is conveyed into the oven through the conveying roller and is dried by using the heating lamp, and the heating lamp is usually fixedly arranged on the top or the side wall of the oven, so that the proper temperature is maintained in the oven to dry the ink.

In view of the above-mentioned related art, the inventor believes that when the printed patterns are different on different packing boxes, the content of the water-based ink on the different printed patterns is also different, resulting in a difference in the drying requirement. And the heating lamps are fixedly arranged on the inner wall of the oven, so that the heating lamps can keep the same drying speed and drying force for the packaging boxes on the conveying roller. When the pattern is small and the ink content is small, the ink may be dried too fast, so that the edge of the print is jagged, and when the pattern is large and the ink content is large, the ink may be dried too slowly, so that the subsequent overprinting effect is affected, and the final printing quality is affected.
