A drum type continuous rotary inkjet printer

Abstract

This application relates to the field of printers, and discloses a drum-type continuous rotary inkjet printer, which includes a printing drum, a paper feeder and a nozzle trolley, and a notch along the axial direction of the printing drum is provided on the cylindrical surface of the printing drum. There are paper teeth on the top; the paper teeth include a rotating shaft and a tooth piece fixed on the rotating shaft. One end of the rotating shaft is connected to a motor, and the tooth piece can be pressed against the cylindrical surface gap of the printing drum under the action of the rotating shaft. The position is pressed against the paper; the printing drum is provided with a vacuum adsorption layer, and its cylindrical surface is provided with a through hole, and the through hole communicates with the vacuum adsorption layer.

Description

technical field [0001] The present application relates to the field of printers, in particular to a drum type continuous rotation inkjet printer. Background technique [0002] For the multi-pass printing method of inkjet printing, in general, the spraying is carried out during the reciprocating lateral movement of the nozzle trolley. The nozzle trolley goes through startup acceleration, uniform printing and deceleration to stop. If it is one-way printing, you need to quickly reset to one side and repeat the above process; if it is two-way printing, you need to reciprocate the above process, and because the directions of the two printings are different, the trajectory of the ink dots is also different, which will inevitably cause Decrease in print quality. [0003] Therefore, a drum-type inkjet printer has appeared in the prior art, and the drum-type inkjet printer realizes printing through continuous rotation of the printing drum, so as to avoid the above-mentioned shortco...
