Continuously moving the position of the clamping device 2 to enable the conical bottle to be subjected to jet printing to enter a preset ink-jet printing position, wherein the conical bottle to be subjected to jet printing is positioned below the shading plate 81 at the ink-jet printing position; turning on the LED lamp set 271 of the heating and curing mechanism 27, moving the carriage mechanism 32 along the Y-axis slide 5 toward the direction close to the light shielding plate, so that the nozzle 321 of the carriage mechanism 32 moves to the ink jet printing position, and detecting (by a second light intensity sensor not shown in the figure on the nozzle 321) the light intensity at the nozzle 321, if the light intensity is too high, adjusting the light intensity of the LED lamp set 271, if the light intensity is suitable, the first motor 26 drives the conical bottle to rotate, the nozzle 321 of the first color starts the jet printing, and the LED lamp set 271 plays a role of pre-curing in the jet printing process, so as to prevent the ink from flowing; according to the equipment, spray heads 321 of various colors can be arranged according to the requirements of spray printing colors, for example, six colors of spray printing are required, namely 6 spray heads 321 are required, after the spray head 321 of a first color finishes spray printing, the spray heads 321 of other colors work in turn until ink jetting is finished, the ink vehicle mechanism 32 moves reversely along the Y-axis slide rail 5, so that the ink vehicle mechanism 32 moves to a parking position, and the spray heads 321 are arranged on the flash spraying moisturizing mechanism; and the light intensity of the LED lamp group 271 is increased, the ink on the conical bottle is solidified and discharged, and the jet printing work is finished.
The above are merely preferred embodiments of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
