Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machine thread hooking, in particular to an embroidery machine thread hooking device, an embroidery machine head and an embroidery machine. Background Art

[0002] There are mainly two types of embroidery machines: single-needle embroidery machines and double-needle embroidery machines. The so-called single-needle embroidery machine does not mean that it has only one needle bar, but that in the embroidery state, one needle bar drives the cam to drive only one needle bar to embroider. In contrast, a double-needle embroidery machine means that in the embroidery state, one needle bar drives the cam to drive two needle bars to embroider at the same time. During the operation of the embroidery machine, it is necessary to frequently switch between different colors of embroidery threads, and each time the embroidery thread is switched, the embroidery thread of the previous color must be cut first, and then the upper thread must be hooked to the upper thread clamp through the thread hooking device to prevent the vibration generated during the operation of the embroidery machine from causing it to fall off the embroidery needle.
