Problems solved by technology

[0005] However, during the operation of the inkjet printer, a phenomenon in which the pressure control by the pressure regulating device is slightly shifted is generated, and although the error in the pressure control process is not a big problem under normal circumstances, in the production of the latest ultra-precision During the production process, the error in the pressure control process gradually becomes a problem

Abstract

The present invention relates to a pressure adjusting device which maintains the precision of pressure control even during use of the inkjet printer and the pressure adjusting device includes an output tube which is connected to an ink reservoir; at least one pressure generator which is capable of changing the pressure in the ink reservoir; an adjusting valve which is positioned between the pressure generator and the output tube; a control unit which controls the adjusting valve to control an output pressure; a pressure sensor which measures pressure information which is output to the output tube so that the control unit is capable of adjusting the adjusting valve; and a temperature sensor which measures temperature information so that the control unit is capable of performing a temperature correction with respect to the pressure information measured at the pressure sensor.

Description

technical field [0001] The invention relates to a pressure regulating device connected with an ink container of an inkjet printer, in particular to a pressure regulating device applied to the inkjet printer used in the industrial field. Background technique [0002] Generally, the inkjet method of ejecting liquid ink in the form of droplets onto the surface of a medium according to a shape signal is used not only for printing of written documents or banknotes but also for solution processing in the fields of semiconductors or displays. [0003] The range of applications of inkjet printing, which is capable of forming complex patterns on a substrate or precisely discharging ink only at specific locations, is expanding. Small inkjet printers for document writing have a form in which ink is stored in an inkjet head that discharges ink droplets, but since large printers for document writing or inkjet printers for industrial use use a large amount of ink, the , the ink container...
