AI Technical Summary
Technical Problem
Traditional spray dyeing equipment cannot adjust the nozzle position and spray width in real time, which makes it impossible to match the width changes of the object to be dyed, resulting in low spray dyeing efficiency.
Method used
The edge and width data of the object to be dyed are obtained by the width detection device. The actual width and position offset are calculated by the control unit. The spray width and position of the nozzle are adjusted in real time to dynamically match the width requirements of the object to be dyed.
Benefits of technology
It achieves dynamic adjustable width dyeing, reduces ink waste, and can continuously dye fabrics of different widths, significantly improving dyeing efficiency.

Abstract
本发明涉及一种进行可调幅宽喷染的方法和喷染系统。该方法包括：经由位于喷染区域之前的幅宽检测装置，获取关于待喷染对象的边缘和幅宽的检测数据，在喷染区域配置有可调幅宽的喷头；控制单元基于来自幅宽检测装置的检测数据，计算待喷染对象的实际幅宽和相对于喷头的位置偏移量；基于所计算的实际幅宽，实时调整目标供液流量，以便基于所调整的目标供液流量以恒定流量的方式向喷头供给墨水；以及基于所计算的实际幅宽和位置偏移量控制喷头的自身喷染幅宽和 / 或喷头位置，以便经由喷头输出墨水的有效幅宽与待喷染对象的实际幅宽相匹配。
