Problems solved by technology

The existing drying system adopts the drying system with air intake from the upper cabinet of the oven and exhaust air from the upper cabinet of the oven. Due to structural limitations, the position of the hot air inlet and exhaust outlet of this structure is relatively concentrated, resulting in low hot air utilization efficiency and energy consumption. big disadvantage

Abstract

The invention discloses a printing press dry box comprising an air inlet arranged on the side wall of the dry box, and an air outlet arranged on a dry box top cover, multiple blast nozzles are arranged on the positions, horizontal to the air inlet, in the dry box, the blast nozzles directly face substrates on a guide roll assembly, multiple return ducts are arranged on a middle baffle of the dry box, the exits of the return ducts face towards the dry box top cover. The design of the dry box is reasonable, the V-shaped blast nozzles directly face the substrates on the guide roll assembly, so that the air circulation in the dry box can be guaranteed to be smooth, the heat wind loss is reduced, the energy saving is realized, clear patterns of presswork can be guaranteed, and the printing ink transfer is uniform.

Description

technical field [0001] The invention belongs to the technical field of printing machinery and relates to a printing machine drying box. Background technique [0002] The main structure of the gravure printing machine is composed of five parts: paper feeding, ink feeding, printing, drying, and paper delivery. Among them, the drying part is hot air heated by electricity or steam, and some use infrared or far-infrared lamps to make printed matter dry. The drying of the printed matter of the printing machine usually needs to be completed by an oven. The drying method of the oven is as follows: an electric heating tube is installed inside the oven, and a hair dryer is installed outside the oven. The passed printed matter is dried, and the exhaust air is discharged from the exhaust channel on the side of the oven. [0003] In the gravure printing process, when a variety of different color registration printing technology equipment is used, there is no need for positioning, and t...
