Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and particularly relates to a drying device for a gravure printing machine. Background Art

[0002] A gravure printing press uses an intaglio plate for printing. The image and text portion of the plate is recessed, while the blank portion is flush with the outer circumference of the plate cylinder. During printing, the entire plate cylinder is inked. A doctor blade removes the ink from the blank portion of the plate, leaving the ink on the image and text portion. The paper is then passed over, and the impression cylinder presses the back of the film, transferring the ink from the recessed portion directly to the film. Finally, the printed product is wound and stacked or rewound. Products printed using gravure printing have advantages such as a thick ink layer, rich layers, a strong three-dimensional effect, and excellent print quality. They are primarily used for printing delicate color images, trademarks, decorative items, securities, and color newspapers. Because the film used in gravure printing often contains a large amount of ink, a drying device is required to accelerate its drying.

[0003] After searching, the utility model with the authorization announcement number CN217435293U discloses a drying device for a gravure printing machine, including a fixing component, and also including: the fixing component includes a fixing box, the front and back sides of the inner side of the fixing box are fixedly sleeved with two first bearings, the inner sides of the first bearings are fixedly sleeved with a first roller, the front and back sides of the inner side of the fixing box are fixedly sleeved with two second bearings, the inner side of the second bearing is fixedly sleeved with a second roller, the front side of the fixing component is fixedly connected to a heating component, the heating component includes a heating mechanism, the back side of the heating mechanism is fixedly connected to a heating tube, the outer side of the heating tube is fixedly connected to a heating plate fixing groove, the top of the inner side of the heating plate fixing groove is fixedly connected to a heating plate, and the top inside the fixed box is fixedly connected to a curing lamp component, which is conducive to quickly drying and curing the ink on the printed matter after printing is completed by the gravure printing machine, saving the time for drying the ink and effectively improving the processing efficiency of the equipment.

[0004] The above technical solution, while drying, drives the rotating shaft to rotate through the fan blades, and then drives the fan blades to rotate, extracting the air and evaporated ink gas inside the fixed box, and adsorbing the toxic substances therein through the adsorption of the activated carbon adsorption block, which is beneficial to remove the irritating gas and toxic gas evaporated by the ink, avoiding direct inhalation by workers into the body, and ensuring a good working environment for the staff. However, the above technical solution is only equipped with a heating and drying device on the lower side of the interior, and can only dry from one side of the paper. Since the ink is thick, it takes a long time to dry the ink thoroughly, resulting in poor ink drying efficiency. In addition, the above solution is not designed with a fixing mechanism when in use, resulting in the paper being unable to be fixed during transportation, and problems such as paper offset or curling may occur, affecting the smoothness of paper transmission.
