Abstract

The invention belongs to the technical field of printing equipment, and in particular, relates to a digital printing and air sucking device and a digital printing machine. The digital printing and airsucking device comprises a printing platform and an air sucking cover plate; the printing platform is provided with a negative-pressure groove; the air sucking cover plate covers the negative-pressure groove, and is provided with multiple air sucking runners arranged side by side; each air sucking runner extends in a moving direction of a medium in a wave or sawtooth form; and multiple air sucking holes arranged in each air sucking runner in the extension direction. The air sucking area of the air sucking holes is changed from a hole form to a whole air sucking runner, so that the air suckingarea of the air sucking holes is increased, and the medium can be dried more uniformly; the dried medium is more smooth and not easy to drape; meanwhile, the drying speed is accelerated; and gaps between the runners can level the medium, so that the areas, recessed into the air sucking runners, of the medium can be leveled by the gaps between the runners during drying and curing, and the medium can be cured more smoothly and is not easy to drape.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a digital printing air suction device and a digital printing machine. Background technique [0002] In the printing or printing device, the thermal transfer paper passes through the printing platform, and the print head ejects a large amount of ink onto the thermal transfer paper according to the pattern to be printed. The shrinkage force and tension of the paper after absorbing ink change, and the thermal transfer paper is The flatness of the printing area changes, causing the thermal transfer paper to curl up and become uneven. After the thermal transfer paper is stranded, the ink is sprayed onto the thermal transfer paper, which will easily lead to the deformation of the printed pattern and the printing ghost, making the printing unclear. The usual method is to set up a suction hole on the printing platform, and the suction hole sucks the air, and at th...
