Embroidery machine thread trimming mechanism with thread buckling electromagnet below shuttle box and computer embroidery machine

Abstract

The invention relates to the technical field of embroidery machines, and provides an embroidery machine thread trimming mechanism with a thread buckling electromagnet below a shuttle box and a computerized embroidery machine. The thread trimming mechanism comprises: the shuttle box (1); a rotating shuttle (2); a thread trimming assembly (3), comprising a movable cutter (32) and a fixed cutter (31), wherein the fixed cutter is fixed on the shuttle box, and the movable cutter can move relative to the fixed cutter to trim a thread; a thread buckling assembly (4), comprising the thread buckling electromagnet (41), a thread buckling pull rod (42), a thread buckling fork (44) and a thread buckling fork swing rod (43), wherein the thread buckling fork is fixed to the thread buckling fork swing rod, the thread buckling electromagnet is arranged below the shuttle box and connected with the thread buckling fork swing rod through the thread buckling pull rod, and the thread buckling fork swing rod is driven by the thread buckling electromagnet to swing and drives the thread buckling fork to buckle up the rotating shuttle; and a thread trimming pull rod (5), which is used for pulling the movable cutter to rotate. The embroidery machine thread trimming mechanism provided by the invention is extremely small in occupied space, can correspond to a special ultra-small head distance, not only can save labor, but also can improve the pattern quality.

AI Technical Summary

Benefits of technology

This patented technology allows for precise cutting of threads with minimal space requirements while maintaining high productivity rates. It uses an electric magnet attached to one part of the device called the wire guiding plate (WGP) or other means like screws inside it's housing. By positioning this magnetic field close enough behind each side of the WGP, tiny cutter blades move backward without being blocked up too much during operation. Overall, these technical features improve the efficiency and accuracy of sewing machines used today.

Problems solved by technology

The technical problem addressed in this patented text relates how to efficiently trim threads at very short distances from an ultrasonic sewing device without wasting time or causing any changes on the final product being produced due to manual operation by workers who are unable to accurately cut these lines down within certain limits.
