Mechanism for mounting and adjusting spray heads of inkjet printer

Abstract

The invention discloses a mechanism for mounting and adjusting spray heads of an inkjet printer. The mechanism comprises a base plate and an adjusting mechanism, wherein the base plate is provided with at least two spray head mounting positions; each spray head mounting position is provided with a fixed spray head or a movable spray head; the fixed spray head is fixedly arranged on the spray head mounting position; the movable spray head is connected with the adjusting mechanism; and the adjusting mechanism adjusts the transverse and longitudinal relative positions between the spray heads and adjusts the angle between the spray heads by controlling the movement of the movable spray head. The mechanism for mounting and adjusting the spray heads of the inkjet printer has a simple structure and high adjustment accuracy, can adjust the spray heads in a plurality of directions, and is convenient to mount and maintain.

Description

technical field [0001] The invention relates to an installation and adjustment mechanism of a spray head of an ink-jet printer, in particular to an installation and adjustment mechanism of a high-precision print head of an ink-jet printer. Background technique [0002] Inkjet printers print images or text by spraying ink droplets on the printing medium through the nozzle. Due to the large amount of data in inkjet printers, in One-pass printing, multiple nozzles are usually connected in series to increase the printing width and printing speed. Multiple nozzles are installed on the nozzle installation and adjustment mechanism to work at the same time. Since the machining accuracy is about 1mm, and the accuracy required by the printer is on the order of 0.01mm, it can be seen that the machining accuracy is far from meeting the printer's accuracy requirements. In order to ensure that the spray point of the nozzle is accurate, the relative physical position between the nozzles i...

AI Technical Summary

Problems solved by technology

For nozzles with low printing accuracy, the adjustment accuracy requirements can be met, but for nozzles with high printing accuracy, it is more troublesome to adjust, with large errors, and it is difficult to meet the adjustment accuracy requirements

Moreover, the existing adjustment mechanism generally adjusts the above three parameters first, and then locks each mechanism. During the locking process, the adjusted mechanism often deviates.
