like figure 1 As shown, for the high-precision nozzles realized by the interpolation arrangement of multiple rows of low-DPI nozzle holes with the same DPI value, the resolution is 200DPI-600DPI. This type of nozzles generally uses one-pass printing, such as Figure 3a As shown, if the nozzle is perpendicular t

Embodiment Construction

[0030] Such as Figure 4 As shown, the nozzle module adjustment mechanism of the present invention can realize the adjustment of the print nozzle module in five degrees of freedom, that is, move along the X axis and the Z axis, and rotate around the X, Y, and Z axes. During the printing process, the nozzle is completely parallel to the printing medium, and completely parallel to the moving direction of the printing medium, which improves the inkjet printing quality.

[0031] The print head module adjustment mechanism of the inkjet printer of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 5 , 6, 8 and 16, the inkjet printer printing head module adjustment mechanism of the present invention includes a bracket 2, a rear mounting plate 3 and a nozzle module mounting plate 4, two optical axes 21 parallel to each other are set on the support 2, Four sliders 23 and a sliding plate 22 are sleeved on th...

Abstract

The invention discloses a mechanism for adjusting a printing spray head module of an inkjet printer. The mechanism comprises a support, a back mounting plate and a spray head module mounting plate, wherein the support is provided with a plain shaft; the plain shaft is provided with a horizontal shift mechanism and a driving mechanism; the horizontal shift mechanism and the driving mechanism can move along the plain shaft; the back mounting plate is arranged on the horizontal shift mechanism, can move left and right together with the horizontal shift mechanism along the plain shaft, and is provided with a vertical shift mechanism and an XY axis deflection mechanism; the XY axis deflection mechanism can deflect relative to an X axis and a Y axis; the vertical shift mechanism is connected with the XY axis deflection mechanism, can move up and down and can deflect along with the XY axis deflection mechanism; the spray head module mounting plate is connected and locked with the vertical shift mechanism through a connecting and locking mechanism and can move up and down along with the vertical shift mechanism; and a spray head module can deflect relative to a Z axis through a Z axis deflection mechanism. The mechanism for adjusting the printing spray head module has a simple structure, can adjust the printing spray head module at five degrees of freedom, ensures that a spray head and a print medium are completely parallel with each other during printing, and is completely vertical to the motion direction of the print medium to improve the inkjet printing quality.

Description

technical field [0001] The invention relates to an adjustment mechanism of a print head module of an inkjet printer. Background technique [0002] Inkjet printers spray ink droplets on the printing medium through nozzles to print images or text. There are two printing methods of inkjet printers, one is that the printing carriage reciprocates back and forth, and the printing medium makes stepping motion along the direction perpendicular to the direction of the printing carriage; the other printing method is that the printing nozzle module does not move, and the printing Media movement, that is, one-pass printing, such as figure 2 shown. Such as figure 1 As shown, for the high-precision nozzles realized by the interpolation arrangement of multiple rows of low-DPI nozzle holes with the same DPI value, the resolution is 200DPI-600DPI. This type of nozzles generally uses one-pass printing, such as Figure 3a As shown, if the nozzle is perpendicular to the printing medium dur...
