Embodiment Construction

[0034] Hereinafter, an inkjet printer according to an embodiment of the present invention will be described with reference to the drawings.

[0035]

[0036] figure 1 The piping diagram of the inkjet printer according to this embodiment is shown in FIG. In addition, figure 2 A block diagram of the control system of the above printer is shown in. As mentioned above, the main purpose of the present invention is to suppress the evaporation of the ink solvent, therefore, figure 1 and figure 2 , The printing-related components that are not related to suppressing the evaporation of ink solvent are omitted.

[0037] Such as figure 1 As shown in the piping diagram, an inkjet printer (hereinafter referred to as "printer") 1 is configured to include: an ink cartridge 2, which stores ink I; and a print head 3, which ejects the ink to print on the surface of the object Printing; pump 4, which outputs ink; tubes 5a to 5j (hereinafter, also collectively referred to as "tube 5"), which connect...

Abstract

The invention provides an ink jet printer, which can control the consumption of ink and maximally inhibits the increasing of price and volume. The ink jet printer comprises a solvent evaporation inhibition mechanism (10), which maintains the air pressure in an ink box (2) to be greater than the value of the saturated vapor pressure of the ink solvent. The solvent evaporation inhibition mechanism (10) comprises a pipe (5i), which is installed on the body (21) or lip (22) of the ink box (2); and a non-return valve (58), which is arranged in the middle of the pipe (5i) and is opened, when the airpressure in the pipe exceeds a predetermined value; the air pressure of the ink box (2) is greater than the value of the saturated vapor pressure of the ink solvent, and thus the evaporation of the ink solvent is inhibited.

Description

Technical field [0001] The present invention relates to a continuous inkjet printer, and more specifically, to an inkjet printer provided with a mechanism for suppressing evaporation of ink solvent recovered by a groove. Background technique [0002] In a continuous inkjet printer, among the ink droplets ejected from the nozzles of the print head, the ink droplets used for printing are deflected to fly and are ejected onto the surface of the printed object. On the other hand, ink droplets that have not received the flight path correction and are not related to printing are stored in the groove, and are collected into the ink cartridge through the collection tube. [0003] The ink recovered to the ink cartridge is transported with air, where the air is discharged from the ink cartridge. [0004] However, inks used in inkjet printers generally use highly volatile solvents such as methyl ethyl ketone. Therefore, when recycled into the ink cartridge, a considerable amount of solvent vap...
