Printer

Abstract

The invention discloses a printer, comprising a printer body and a radiating drier, wherein the radiating drier comprises a box body device in which the material to be dried can be put and a radiating device which is internally embedded into the box body device and used for garneting radiation, and the radiating device is internally provided with a launcher capable of generating electromagnetic wave. When the electromagnetic wave generated by the launcher is irradiated on the material to be dried, the solvent molecules in the material to be dried repeatedly steer and move under the repeated alternating magnetization of an electric field and a magnetic field, so that the high-speed vibration is formed, the kinetic energy is increased, and the heat energy is sequentially increased; finally, the solvent molecules are heated to leave from the surface of the material to be dried to enter gas phase, so that the effect of material drying can be achieved; and the protective gas is charged in the process of drying, so that the material to be dried can not be oxidized, burnt, exploded and the like when the material is dried.

Description

technical field [0001] The invention relates to a printing machine, in particular to a printing machine which uses radiation for drying. Background technique [0002] With the rapid development of the printing industry, printing machines are developing in the direction of multi-color, multi-functional and in-line processing, and the printing speed is also increasing. In order to further increase the printing speed of the printing machine and improve production efficiency, the drying device is one of the most important restrictive factors. If the printed matter cannot be dried quickly and well, the corresponding printing speed cannot be improved. The drying equipment in the prior art generally adopts boilers to supply steam, resistance heating, quartz tube heat sources, heat pumps, or directly burn firewood, coal and other heat sources to act on the object to be dried, and the heat energy reaches the inside of the object through heat transfer, and gradually removes the moistu...

AI Technical Summary

Problems solved by technology

The above methods are to transfer or conduct heat from the outside of the object to the inside of the object after being heated. Often the water on the surface of the object will evaporate first, which will cause the surface to shrink, deform and crack. Moreover, this drying method takes a long time to dry and consumes a lot of energy. Disadvantages such as high cost and large space occupation due to large equipment volume
