Protective board device for embroidery machine thread hooking

Abstract

The invention discloses a protective plate device for thread hooking of an embroidery machine. An upper sleeve is fixed on the upper side of the right side of the protective plate, and a lower sleeve is fixed on the right side of the protective plate on the lower side of the upper sleeve. The axis lines of the upper sleeve and the lower sleeve coincide. The upper sleeve and the lower sleeve are provided with a movable shaft, the lower end surface of the movable shaft is fixed with a hook plate, and the lower end surface of the hook plate is welded with a hook knife, and the movable shaft between the upper sleeve and the lower sleeve A fixed ring is welded on the side of the shaft. The invention realizes the periodic lifting of the movable shaft by setting the upper sleeve, the lower sleeve, the hook plate, the hook knife, the swing arm, the turntable, the driving rod and the servo motor, and the movable shaft drives the hook knife to perform hooking. Line operation, through the limit of the upper sleeve, the lower sleeve and the protruding shaft, the movable shaft runs stably, is not easy to deflect, and has high working efficiency.
