Printing module adjusting device and adjusting method thereof

Abstract

The invention discloses a heavy printing module adjusting device and an adjusting method thereof. The heavy printing module adjusting device comprises a printing module, an adjusting mechanism and an installation plate; the printing module is connected with the adjusting mechanism through the installation plate; and one part of the adjusting mechanism is connected to the printing module, and the other part of the adjusting mechanism is connected to the installation plate. The heavy printing module adjusting device is characterized in that the adjusting mechanism comprises three-shaft adjusting mechanisms and a vertical adjusting mechanism; the three-shaft adjusting mechanisms comprise a left three-shaft adjusting mechanism and a right three-shaft adjusting mechanism which are symmetrically arranged on the left side and the right side of the installation plate and the printing module respectively; the vertical adjusting mechanism is vertically arranged in a centre line position of the installation plate along a vertical direction; and the installation plate is combined with the printing module through the left three-shaft adjusting mechanism, the right three-shaft adjusting mechanism and the vertical adjusting mechanism. Through cooperative operations of adjusting bolts on the three-shaft adjusting mechanisms in three directions and vertical adjusting bolts on the vertical adjusting mechanism, the adjustment of six freedom degrees of the printing module can be realized; and the heavy printing module adjusting device has the advantages of convenience in operation and high adjustment precision.

Description

technical field [0001] The invention relates to a printing module adjusting device and an adjusting method thereof, in particular to a heavy digital equipment printing module adjusting device and an adjusting method thereof. Background technique [0002] Inkjet printing technology has become an important part of digital printing technology with its advantages of no contact, no pressure, and adaptability to various media. Inkjet printers eject liquid ink of one or more colors from multiple nozzles. The tiny ink droplets of liquid are formed on the printing medium to realize the printing of text and images. In the process of inkjet printing, in order to achieve a good printing effect, an appropriate distance and angle must be maintained between the nozzle of the printer and the printing medium. [0003] In One-Pass (single-pass) printing, in order to increase the printing width, generally multiple nozzles are connected horizontally end-to-end to increase the required printing...

Problems solved by technology

[0010] In order to maintain a proper distance and angle between the nozzle of the printer and the printing medium, necessary adjustments are required. However, in the prior art, the adjustment distance and the adjustment angle are mostly adjusted separately, and the adjustment distance is mostly adjusted by an eccentric wheel or a cam. , such as patent US20010899292, US6575543B2, patent US20040008231A1 also provides a method of using a stepped shaft to push the print head support beam to adjust the vertical direction, so as to maintain a suitable distance between the printer nozzle and the printing medium. Using these methods can realize the nozzle in Z The axial direction is precisely adjusted, but the angle of the nozzle relative to the printing medium cannot be adjusted. Patent CN03147858.1 provides a method for adjusting the angle between the nozzle and the printing medium. The pressing adjustment unit and the elastic pressing unit work together to push the printing head Deflect a certain angle to adjust the angle of the nozzle relative to the printing medium. This direction can be used to adjust the angle of the nozzle relative to the printing medium, but the distance between the nozzle and the printing medium cannot be adjusted, and this method is only applicable to a single nozzle. Adjustment, when many nozzles are installed in one printing module with the same offset angle, it is time-consuming and laborious to use this method to adjust one by one
