As shown in fig. 1-4, a high-precision positioning printing mechanism comprises an alignment mechanism 1, wherein the alignment mechanism 1 comprises an alignment mechanism housing 11, a scraper horizontal movement linear module 2 is fixedly mounted on the upper surface of the alignment mechanism housing 11, and a scraper return ink knife lifting mechanism 3 is connected to the scraper horizontal movement linear module 2; the scraper horizontal movement linear module 2 is used for driving the scraper ink return blade lifting mechanism 3 to move horizontally to complete printing work.

The scraper ink return blade lifting mechanism 3 comprises a lifting mechanism shell 31, the lifting mechanism shell 31 is connected with the scraper horizontal movement linear module 2, and a scraper lifting servo motor 32 and an ink return blade lifting servo motor 33 are fixedly mounted on the lifting mechanism shell 31.

Scraper lift servo motor 32 below is connected with scraper lift module 34, fixed mounting has slip table cylinder 35 on the scraper lift module 34, be fixed with scraper 36 on the output shaft of slip table cylinder 35, scraper 36 specifically is the self-balancing scraper that suspends. The scraper lifting servo motor 32 drives the scraper lifting module 34 to move up and down, and then drives the sliding table cylinder 35 and the scraper 36 to move up and down; and the printing is realized by adopting different pressures aiming at different products by adjusting the output pressure of the sliding table cylinder 35.

An ink return blade lifting module 37 is connected below the ink return blade lifting servo motor 33, and an ink return blade 38 is fixed below the ink return blade lifting module 37. Leveling screws 39 are arranged on the ink returning knives 38, and uniform ink returning control is achieved. The ink return blade lifting servo motor 33 drives the ink return blade lifting module 37 to move up and down, and further drives the ink return blade 38 to move up and down.

The lower surface of the alignment mechanism housing 11 is fixedly provided with an X1 alignment mechanism motor 12, an X2 alignment mechanism motor 13 and a Y alignment mechanism motor 14 through a connecting piece 15, output shafts (output shafts are shielded by the connecting piece 15 in the figure and are not marked) of the X1 alignment mechanism motor 12, the X2 alignment mechanism motor 13 and the Y alignment mechanism motor 14 are all connected to corresponding translation mechanisms 17 through lead screws 16, and the translation mechanisms 17 are respectively and fixedly installed on corners of the upper surface of the screen fixing frame 18. The output shaft directions (this direction is the X axis) of the X1 alignment mechanism motor 12 and the X2 alignment mechanism motor 13 are parallel to each other, and are perpendicular to the output shaft direction (this direction is the Y axis) of the Y alignment mechanism motor 14. The output shafts of the X1 alignment mechanism motor 12, the X2 alignment mechanism motor 13, and the Y alignment mechanism motor 14 rotate to drive the screw rod 16 to rotate, and then the screw rod 16 drives the translation mechanism 17 to move along the axial direction of the screw rod 16.

The moving direction of the slide block 19 in the translation mechanism 17 is vertical to the axial direction of the corresponding screw rod 16; then, when the translation mechanism 17 corresponding to the X1 alignment mechanism motor 12 and the X2 alignment mechanism motor 13 moves along the X axis as a whole, the slider seat 20 in the translation mechanism 17 corresponding to the Y alignment mechanism motor 14 also moves along the X axis; when the entire translation mechanism 17 corresponding to the Y-position mechanism motor 14 moves along the Y-axis, the slider holder 20 in the translation mechanism 17 corresponding to the X1-position mechanism motor 12 and the X2-position mechanism motor 13 also moves along the X-axis.
