7. The printing method of the multifunctional inkjet marking device according to claim 1, characterized in that: The printing method includes the following steps: a) The pre-printed profile is horizontally conveyed to the marking area via a feeding platform, ensuring that the outer edge of the profile is tangent to a set of limiting mechanisms. The limiting mechanisms provide initial positioning of the profile in the Y-axis direction; b) A drive cylinder moves the horizontal moving mechanism and the marking device forward together. The limiting mechanism located in front of the horizontal moving mechanism contacts and presses the profile, ensuring precise positioning of the profile in the Y-axis direction; c) A vertical cylinder moves the marking mechanism downward. The rollers on the marking mechanism contact and press the profile. This allows for precise positioning of the pre-cut profile in the Z-axis direction; d) The first and second sensors on the inkjet marking mechanism locate the profile, first checking if it is in place, and then finding the zero-point position for printing; e) The inkjet marking device operates, accurately printing the pre-printed content, including characters, Chinese characters, numbers, patterns, and reverse straight lines, onto the profile surface; f) After printing, the vertical cylinder operates, the inkjet marking mechanism returns to its origin, and then the drive cylinder operates, the front limit mechanism and the horizontal moving mechanism move backward, and the profile is transported to the cutting room for cutting.
