  • Mechanism for seamlessly splicing nozzles
    Patent number: 10059105
    Abstract: The present invention provides a nozzle seamless splice mechanism and an adjustment method for the same, and belongs to a field of printing machinery technology. The nozzle seamless splice mechanism and the adjustment method for the same may solve the problems of nozzles orifices stagger, reduced printing width or blankness exposed in the middle caused by the causes such as the fabrication error, the personal error, etc with respect to the existing nozzles. The nozzle seamless splice mechanism of the present invention comprises: splice mechanism comprising: a micro-device for detecting coordinates of orifices of nozzles; a nozzle adjustment base for fixing nozzles; a nozzle bottom plate connected with said nozzle adjustment base adjustably. The nozzle seamless splice mechanism of the present invention has a low cost, high adjustment efficiency, and achieves digitized adjustment.
