Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paperboard printing, in particular to the technical field of printing drying machine. BACKGROUND

[0002] Modern printing system is generally composed of plate mounting, ink coating, impression, paper feeding (including folding) and other mechanisms. Its working principle is: first, the text and images to be printed are made into printing plates, which are mounted on the printing machine, then the printing machine applies ink to the places with text and images on the printing plate, and then directly or indirectly transfers to paper or other printing materials (such as textiles, metal plates, plastics, leather, wood, glass and ceramics), thereby copying the same printing plate to reproduce the same printing plate.

[0003] After printing, the printing material needs to be sent into the drying machine for drying. The existing drying machine generally sends the paperboard into the drying box through the conveying belt for drying one by one, which takes a long time and has low drying efficiency. If the drying of multiple printing materials is to be performed at one time, the drying box needs to be made into a long strip shape, which has a large floor area and is not convenient for small printing plants to use.
