Problems solved by technology
[0004] The upper thread automatic thread locking and clamping mechanism of the computerized embroidery machine in the above patent has the following disadvantages; there are too many interlocking mechanisms in the middle of the thread clamping mechanism during use, including electromagnets, second conflicting plates, rotating shafts, first conflicting plates, moving Rod, any one of the connections has a temporary or permanent jamming phenomenon, such as a foreign object between the shaft and the mounting bracket, causing the shaft to be stuck. At this time, if there is external influence such as static electricity or wind, the thread will be separated from the sewing machine

The invention discloses a thread locking device and an embroidery machine including the same, and solves the problems of poor stability and easy jamming of thread locking devices. According to the key points of the technical scheme, the thread locking device is characterized by including a thread frame and a push rod, the upper end of the thread frame is provided with a plurality of upper thread holes, a positioning plate is arranged between a first side wall and a second side wall of the thread frame, the positioning plate is provided with lower thread holes corresponding to the upper thread holes, a clamp block is fixed above the positioning plate and fixes a slide rod running through the first side wall and the second side wall, the slide rod is sleeved with an elastic element for maintaining the motion tendency of the clamp block to the first side wall, the push rod includes a dynamic part controlling its reciprocating motion, driven by the dynamic part, the push rod can push the movement of the slide rod toward the second side wall, after removal of a connecting mechanism between the slide rod and the dynamic part in a thread clamp process, the error rate of the thread locking device is reduced, thus reaching the purpose that an embroidery machine using the thread locking device provided by the invention can be more stable during thread clamp.
Description
technical field [0001] The invention relates to the field of embroidery machine production, more specifically, it relates to an embroidery machine thread locking device. Background technique [0002] Embroidery machine, embroidery machinery, includes a positioning plate with a small round hole, and the sewing machine needle keeps going in and out of the round hole to achieve the purpose of embroidery. When the embroidery machine is in use, the distance from the embroidery thread to the sewing machine needle is too long. However, when the embroidery machine is out of use, under the interference of external factors such as static electricity and wind, the thread will break away from the sewing machine needle. [0003] The patent document published in China with the application number 201420378896.2 before the application is a computerized embroidery machine with an automatic upper thread locking mechanism, which discloses: when the computerized embroidery machine works, the m...
