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. And after the adjustment is finished, fixing the jackscrew.
The first locking member is a screw. The base 10 is further provided with a positioning hole 50, and a positioning pin penetrates through the positioning hole 50 and is located on one side of the spray head 30. The spray head 30 can be fixed to most of the spray heads on the market by positioning pins and screws.
The flexible hinge 20 has a zigzag structure, so that the two-dimensional flexible hinge 20 can facilitate the adjustment of the position of the spray head 30. In another embodiment, the flexible hinge 20 may be replaced with an in-line version of the resilient plunger and nut assembly.
The ejection head 30 is an inkjet print head.
The plurality of nozzles 30 are arranged in an array, and two adjacent rows of nozzles 30 are arranged in a staggered manner. The plurality of nozzles 30 may be arranged in a delta shape. The base 10 is integrally machined, and the overall size of the system can be greatly reduced due to the triangular layout. The invention provides a four-row mechanism, but the four-row mechanism can be infinitely expanded to a multi-row system according to the design scheme of the invention, and all the four-row mechanism belong to the protection points of the project.
The invention has the following advantages:
the invention optimizes the structural layout, adopts integrated processing, does not need additional elastic parts and guide parts, and has compact integral structure.
The invention avoids excessively relying on machining precision and assembly precision to ensure the final position precision through reasonable mechanism design, and realizes the final position precision through a fine adjustment mode.
The distribution of the flexible hinges 20 on the bases 10 of the four-row spray heads 30 is designed according to the actual size of the product, and the adaptability to different products can be realized by the same structure.
The invention designs a flexible hinge 20 mechanism with multi-directional adjustment, and designs a multi-group ink-jet printing spray head 30 row-in-row structure capable of flexibly and accurately adjusting aiming at the ink-jet printing direction.
The invention adopts a plate-type flexible hinge 20 with a square-shaped structure, and the position of the hinge is adjusted by adjusting the jackscrew. The precise position adjustment in the X direction and the angle direction of the ink-jet printing head can be realized, the flexible hinge 20 mechanism is pushed by the hand-operated adjusting jackscrew, and the fixed printing spray head 30 fixing mechanism is driven, so that the precise position adjustment is realized.
