Description

Height adjusting and controlling method for ink jet head of ink jet assembly Technical Field The invention belongs to the technical field of garment-like garment cutting, and particularly relates to a height adjusting and controlling method of an ink-jet head of an ink-jet assembly. Background In the prior art, three cutting modes exist in the cutting of the clothing sample clothes, namely, firstly, a clothing CAD drawing instrument is adopted to print the pattern of the clothing sample clothes on mark frame paper or kraft paper, then the mark frame paper or kraft paper is paved on the clothing fabric, then the clothing sample clothes are obtained through cutting manually, secondly, firstly, the clothing CAD drawing instrument is adopted to print the pattern of the clothing sample clothes on mark frame paper or kraft paper, then the mark frame paper or kraft paper is paved on the clothing fabric on a single-layer cutting bed, then the point cutting is carried out through single-layer cutting bed alignment, so as to obtain the clothing sample clothes, thirdly, firstly, the mark frame paper or kraft paper is paved on the clothing fabric on the single-layer cutting bed, then the pattern of the clothing sample clothes is printed on the mark frame paper or kraft paper through a jet ink component on a single-layer cutting bed machine head, and finally the clothing sample clothes are obtained through cutting by a cutter of the single-layer cutting bed machine head. However, the first and second cutting modes have certain problems, and the specific analysis is as follows: The cutting mode has the following problems that due to the printing precision problem of the CAD drawing instrument of the clothing, the clothing pattern printed on mark frame paper or kraft paper and the actual clothing pattern have inconsistent dimensional precision, in addition, the time spent for manual cutting is longer, the cutting efficiency is lower, and an operator with skilled cutting skills is required to cut. The second cutting mode has the following problems that due to the printing precision problem of the CAD drawing instrument of the clothing, the clothing pattern printed on the mark frame paper or kraft paper and the real clothing pattern have the inconsistent risk in the dimensional precision, in addition, the mark frame paper or kraft paper printed with the clothing pattern needs to be folded and transported and then spread on the clothing fabric on the single-layer cutting bed, the risk of the inconsistency in the dimensional precision of the clothing pattern obtained after cutting and the real clothing pattern is caused due to the folding reason of the mark frame paper or kraft paper, and the coordinate system used in the process of printing the clothing pattern on the mark frame paper or kraft paper by the CAD drawing instrument of the clothing pattern and the coordinate system used in the process of cutting the single-layer cutting bed are not the same coordinate system, so that the problem of long alignment time exists in the cutting process. In the cutting mode III, when the ink-jet assembly on the single-layer cutting machine head is adopted to spray and print the layout of the clothing sample on the mark frame paper or the kraft paper, the ink-jet head of the ink-jet assembly needs to keep a distance of 3mm with the clothing fabric, otherwise, the spray and print precision has deviation, but when a customer is actually used, the thickness of the clothing fabric and the number of layers of the clothing fabric are inconsistent, the height of the ink-jet head of the ink-jet assembly needs to be manually adjusted, the manual adjustment is complicated, the adjustment precision cannot be ensured, and therefore, the spray and print precision cannot be ensured. Disclosure of Invention In view of the above-mentioned drawbacks of the prior art, the present invention provides a method for controlling the height adjustment of an inkjet head of an inkjet assembly, which can automatically adjust the height of the inkjet head and ensure the adjustment accuracy, thereby ensuring the inkjet printing accuracy.
