Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1-2, the present invention discloses a multi-nozzle 30 row inkjet printing apparatus, which includes a base 10, a plurality of nozzles 30 are disposed on the base 10, a flexible hinge 20 is disposed between each nozzle 30 and the base 10, and the flexible hinge 20 is disposed around the nozzles 30.
A first mounting hole 40, a second mounting hole 41 and a third mounting hole 42 are formed in the base 10, the first mounting hole 40 and the second mounting hole 41 are located on the upper surface of the base 10, and the third mounting hole 42 is formed in the side surface of the base 10; the second mounting hole 41 and the third mounting hole 42 are provided therein with an adjusting member, which is disposed in cooperation with the flexible hinge 20 to adjust the position of the flexible hinge 20. The spray head 30 is connected to the first mounting hole 40 of the base 10 by a first locking member. The flexible hinge 20 is a prior art flexible hinge 20, and the flexible hinge 20 of the present invention is a two-dimensional precision adjustment flexible hinge 20. The nozzle 30 can be precisely adjusted to move along the horizontal direction and the rotating direction by adjusting the adjusting piece, so that the precise positioning of the nozzle 30 is realized. Thereafter, the fixing between the spray head 30 and the base 10 is achieved by the first locking member.
The adjustment member is a jack screw, the end of which abuts against the flexible hinge 20. In the present invention, the spray heads 30 are fixed at the relevant positions of the base 10 by the locking members, then the precise position adjustment is performed by adjusting the jackscrews, and the plane position of each spray head 30 can be adjusted with a very high resolution by matching with the elastic mechanism of the flexible hinge 20, thereby ensuring the precision of the final position of the spray heads 30.
