Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a drying device for ink. Background Technique

[0002] Water-based ink is a kind of ink which is made by compound grinding of water-soluble resin, organic pigment, solvent and related additives. Water-based ink is mostly used as the ink for printed matter, such as the patterns printed on commodity packaging bags. The ink patterns printed on water-based ink printed matter not only have strong adhesion, but also are not easy to oxidize and change color, and the printing cost is low. Therefore, printed matter using water-based ink has extremely wide applications in the industry.

[0003] In the production process, for printed matter with distinct printed patterns, during the printing process, it is necessary to repeatedly spray and print on printing carriers such as corrugated cardboard, kraft paper, and greaseproof paper. After printing, although water-based ink has high volatility and can dry quickly, it can keep the printed matter from sticking due to the ink not being dry. However, for printed matter with a large amount of ink used in the printed pattern (mostly billboards, etc.), because the amount of sprayed ink is large and the pattern color is distinct, the printed matter after printing cannot be stacked immediately. In the actual working process, it is found that after stacking, there is often serious sticking of the printed matter due to the ink not being dry. As long as they are separated, the printed matter patterns will inevitably be damaged. Most of the existing ones are dried by blowing air through a blower, but in this process, the volatilized ink is easy to pollute the surrounding air, which causes irreversible damage to people's respiratory systems.

[0007] The drying mechanism includes a housing installed above the conveying roller path through a support frame. A plurality of electric heating tubes are arranged at the bottom of the housing in the order of the passing sequence of the printed matter from one side to the other side, and the electric heating tubes do not contact the surface of the printed matter. An air inlet cavity and an air suction cavity are respectively arranged at the front and rear ends of each electric heating tube inside the housing, and the air inlet cavity is located at the front end of the electric heating tube, and the air suction cavity is located at the rear end of the electric heating tube.
