Description

TECHNICAL FIELD

[0001] The utility model belongs to inkjet printing technical field, concretely relates to a kind of multi-jet position adjusting device. BACKGROUND

[0002] Inkjet printing is a printing method that uses non-contact inkjet technology. Its basic principle is to eject ink through tiny nozzles in the form of tiny droplets onto the surface of the substrate. These droplets quickly penetrate or are absorbed on the substrate, and after drying, form the required image or text. The inside of the inkjet head contains multiple tiny nozzles, each of which can independently control the ejection of ink. During printing, the inkjet head moves above the substrate according to the predetermined trajectory, while accurately controlling the opening and closing of each nozzle according to the printing data, so that the ink is ejected in the form of tiny droplets onto the substrate. The ink used in inkjet printing has multiple types, including water-based ink, oil-based ink, solvent-based ink and UV-curable ink, etc. These inks have different characteristics in terms of color, drying speed, adhesion and weather resistance, suitable for different printing needs and substrates.

By rotating the adjusting cap 801, the position of the adjusting cap 801 on the long screw rod 804 changes. When the adjusting cap 801 moves downward, the pressing cylinder 802 is simultaneously pressed to slide downward. Since the lower part of the pressing cylinder 802 is tapered and the tapered part of the pressing cylinder 802 is close to the contact head 403 on the thick block 402, the tapered part is pressed on the contact head 403 to change the position of the nozzle 30 (the change of the position in the X-direction).

[0051] In the above scheme, the Y-direction block 70 is extruded by the tapered extrusion cylinder 802, the position of the first elastic sheet 208 is diagonally arranged with the adjusting assembly 80 on the Y-direction block 70, so as to balance the position of the assembly plate 20, and the use of the first elastic sheet 208 can provide a thrust in the opposite direction of the adjusting assembly 80; when the adjusting cap 801 is rotated in the opposite direction, the adjusting cap 801 moves on the long screw 804, at this time, the thrust generated by the first elastic sheet 208 can push the assembly plate 20, so that the contact surface 701 extrudes the extrusion cylinder 802 on the adjusting assembly 80 to move upward, and the compactness of the overall structure is comprehensively associated.

[0052] Further reference Figure 7 And Figure 11 The second elastic sheet 702 is installed above the Y-direction block 70, and the other end of the X-direction block 40 is provided with a thin block 405, and the stress end of the second elastic sheet 702 is in contact with the thin block 405.

[0053] In a further embodiment, the position of the second elastic sheet 702 is opposite to the adjusting assembly 80 on the second positioning hole 203; the X-direction block 40 is extruded by the tapered extrusion cylinder 802, when the X-direction block 40 is offset in the opposite direction of the X-axis, the displacement change will be fed back to the second elastic sheet 702, the second elastic sheet 702 provides a thrust in the opposite direction of the adjusting assembly 80 on the second positioning hole 203, when the position of the extrusion cylinder 802 changes, the extrusion cylinder 802 can slide on the long screw 804, and at the same time, it is also used for timely correcting the installation position of the nozzle 30.

[0054] Finally, it should be noted that the adjusting range of the adjusting assembly 80 of the device is suitable for fine adjustment.

[0055] The specific implementation process of the device is as follows:

[0056] By rotating the adjusting cap 801, the position of the adjusting cap 801 on the long screw 804 changes, when the adjusting cap 801 moves downward, the extrusion cylinder 802 is extruded and slides downward at the same time, because the lower part of the extrusion cylinder 802 is tapered, and the tapered part of the extrusion cylinder 802 is close to the contact head 403 on the thick block 402, so that the tapered part gradually increases or gradually decreases to extrude the contact head 403, thereby pushing the position of the nozzle 30 to change (the direction is the change of the position in the X direction);

[0057] By rotating the adjusting cap 801, the tapered part of the extrusion cylinder 802 is close to the contact surface 701 of the Y-direction block 70, and the contact surface 701 on the Y-direction block 70 is extruded by the gradually increasing or gradually decreasing tapered part, so that the position of the assembly plate 20 is changed (the position change is in the Y direction);
