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.

First claim

What is claimed is:

1. A mechanism for seamless splicing nozzles, comprising:
a microscope for detecting coordinates of orifices of the nozzles within a field of view of the microscope;
a nozzle adjustment base for fixing the nozzles;
a nozzle bottom plate adjustably connected with said nozzle adjustment base;
wherein said nozzle adjustment base is connected with the nozzle bottom plate by a pin screw, said nozzle adjustment base is provided with a long hole through which the pin screw extends, the diameter of said long hole matches the diameter of the pin screw, the direction of said long hole is the same as the arrangement direction of the orifices of the nozzles, said nozzle adjustment base is movable on the nozzle bottom plate in an arrangement direction of said orifices of the nozzles by moving said pin screw in the direction of said long hole, such that a transverse adjustment is performed on said nozzle, and said nozzle adjustment base is rotatable on the nozzle bottom plate with said pin screw as a rotating center, such that a longitudinal adjustment is performed on said nozzle.

2. The mechanism according to claim 1 , wherein said long hole is provided in a middle position on the nozzle adjustment base in the arrangement direction of the orifices of the nozzles.

3. The mechanism according to claim 1 , wherein said nozzle bottom plate is provided with a micrometer head for the transverse adjustment and a micrometer head for the longitudinal adjustment of the nozzle adjustment base.

4. The mechanism according to claim 3 , wherein said micrometer head for the transverse adjustment is arranged on a transverse fixation base, said transverse fixation base is arranged on the nozzle bottom plate; and
said micrometer head for the longitudinal adjustment is arranged on an angle adjustment base, said angle adjustment base is arranged on the nozzle bottom plate.

5. The mechanism according to claim 4 , wherein the adjustment accuracy of said micrometer head is 0.01 mm.
