Description

Technical Field

[0001] The invention belongs to the technical field of embroidery machine yarn clamping color control, and particularly relates to an embroidery machine thread clamping device and method based on yarn color matching pattern color. Background Art

[0002] The embroidery machine thread clamp is an important core component of the embroidery machine for yarn clamping. Its main function is to match the yarns of the respective colors required for the pattern designed by the designer to the corresponding spools on the thread clamp as needed, and then clamp the yarns of various colors through the spools to guide them to the embroidery machine for embroidery. At present, after the color of the pattern on the embroidery machine computer is designed, the spools of corresponding colors on the embroidery machine thread rack are installed manually according to the color of the pattern on the computer. This process is due to the wide variety of pattern colors and the various sequences. For example, the first spool is red, the second spool is blue, and the third spool is red. There are dozens of yarn color sequences on this spool. After changing the pattern, the spools must also be changed. Not only is the workload heavy, but it is also very easy to make matching errors. In addition, since the yarn is relatively thin, it is difficult to judge the position and color of the yarn currently working. How to improve the recognition of the yarn currently working, and how to quickly match the pattern color and the yarn color on the spool, and how to make the embroidery machine thread clamp device and method less prone to errors are the objects of research for technicians in this field.
