Rapid drying device for printing ink on paper surface

Abstract

The invention discloses a rapid drying device for printing ink on the paper surface, and belongs to the field of printing. According to the rapid drying device for the printing ink on the paper surface, due to the arrangement of an outer circulation system, on one hand, a porous drying head can blow out high-temperature air to paper, gas flowing is accelerated, the drying efficiency is improved, meanwhile, pneumatic thread sheets continuously rub with one another under the action of wind power to generate electrostatic force, when the paper is accidentally blown and turned over, the pneumatic wire sheets can generate certain adsorption force on the paper, the paper is effectively prevented from being separated from a conveying belt, on the other hand, negative-pressure adsorption force can be generated on the back face of the paper in cooperation with the action of a plurality of inner adsorption protrusions, so that the paper is temporarily fixed on the conveying belt, the situation that the paper is difficult to turn over and float under the action of wind blowing at the porous drying head when moving along with the conveying belt for drying is effectively guaranteed, then the printing ink is effectively guaranteed not to be scratched, meanwhile, compared with the prior art, the conveying speed can be properly increased, and the drying efficiency is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of printing, and more specifically relates to a rapid drying device for printing ink on a paper surface. Background technique [0002] Ink is a substance used to form graphic information in the printing process. It is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additional materials, etc.; it can be printed, and in Dry on the printed body; it is a paste-like adhesive body with color and certain fluidity. Therefore, color (hue), body (thickness, fluidity and other rheological properties) and drying performance are the three most important properties of ink. There are many types of them, and their physical properties are also different. Some are very thick and sticky; while others are quite thin. Some use vegetable oil as the linking material; some use resin and solvent or water as the linking material. [0003] The ink should have bright...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide a rapid drying device for paper surface printing ink, which is set in the external circulation system. On the one hand, the porous drying head can blow out high-temperature air to the paper to accelerate the gas flow. , so that the drying efficiency is improved. At the same time, the pneumatic filaments are constantly rubbing against each other under the action of the wind to generate electrostatic force. When the paper is accidentally blown up and turned over, it can generate a certain amount of adsorption force on the paper, effectively preventing the paper from leaving the conveyor belt. On the other hand, with the function of multiple internal suction protrusions, it can generate negative pressure adsorption force on the back of the paper, so that it can be temporarily fixed on the conveyor belt, effectively ensuring that it is not easy to dry when it moves with the conveyor belt. Under the wind blowing at the drying head, the flipping and floating situation occurs, which effectively ensures that the ink is not easy to be scratched and scratched. At the same time, compared with the existing technology, the transmission speed can be appropriately increased, thereby effectively ensuring the drying efficiency.
