Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to an adjusting mechanism of an inkjet printing head. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] In the field of printing technology, multiple print heads are typically fixed to a mounting plate to achieve collaborative operation. However, this traditional installation method has significant limitations, particularly in terms of print head positioning accuracy and adjustment flexibility. First, even small errors during the installation process can have a significant impact on the final print quality. These errors can arise from factors such as inaccurate installation positioning and uneven tightening force, causing the print head to deviate from the expected position. In addition, during long printing operations, the print head may also shift due to mechanical wear, thermal expansion and contraction of the material, or external vibration, further exacerbating printing errors. Secondly, changes in ambient temperature are also a significant factor affecting the position accuracy of the print head. As the ambient temperature rises or falls, the print head and its mounting plate may deform due to thermal expansion and contraction, causing the actual position of the print head to deviate from the expected position, thereby affecting print quality.

[0004] However, with existing printing technologies, effective position adjustment is difficult once a print head misaligns. This is primarily due to the rigid mounting system between the print head and the mounting plate, which lacks the necessary adjustment mechanisms or means. Consequently, when a print head misaligns, the machine often needs to be shut down for tedious manual adjustments, potentially even requiring replacement of the entire mounting plate or print head. This not only increases maintenance costs but also severely impacts the continuity and efficiency of printing operations.

It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention.
