Referring to fig. 7, in which the guides are different due to different distributions of the yarn passing wheels 510, and the compact design of the yarn trapper is preferred in consideration of the size of the yarn passing wheels, in the present application, it is preferable that the plurality of yarn passing wheels 510 are designed into two rows, the guide corresponding to the upper row of yarn passing wheels 510 is the yarn passing nail below the upper row, the guide corresponding to the lower row of yarn passing wheels 510 is the guide hook above the lower row and the yarn passing nail below the lower row, and the guide hook and the yarn passing nail as the guides are not shown in the drawing. The installation structure between the wire guide wheel 510 and the panel 110 can refer to the existing structure, and will not be described herein.

More specifically, in this embodiment, the display assembly 600 is a display screen, and the display screen is electrically connected to the circuit board 325 and performs data exchange with the circuit board, so as to display data corresponding to the needle position, tension, electromagnet current, and the amount of the embroidery thread; for the above-mentioned specific internal circuit design and program control design portions related to the circuit board 325, reference may be made to circuit design and program design which can achieve the same function in the prior art, and details are not repeated herein. In addition, the design of the display assembly 600 is convenient for the staff to quickly acquire the relevant parameter information corresponding to the embroidery thread, is convenient for management and monitoring, and improves the stable operation of the embroidery machine to a certain extent.

The working principle of the invention is as follows: installing embroidery thread, wherein the embroidery thread enters from the upper thread-pressing sheet group, is tangent to the corresponding thread-passing nail 411 in the upper thread-passing nail group 410, then passes through between the stainless steel strip 330 and the thread-pressing block 3121, is tangent to the corresponding thread-passing nail 411 in the lower thread-passing nail group 420, then enters into the corresponding thread-passing wheel 510, and then passes through from the lower thread-pressing sheet group; the embroidery thread passes through the regulation of resistance, according to the current needle position of using the line of embroidery machine, embroidery machine drive slip subassembly 323 drives electro-magnet 324 and slides to corresponding embroidery thread department, in embroidery operation in-process, through circuit board 325 control change electro-magnet 324 electric current size, realize attracting line ball 3121 in its place ahead by electro-magnet 324, make line ball 3121 push down stainless steel strip 330, through changing the size of line ball 3121 and stainless steel strip 330 clamp force, thereby change the through resistance of embroidery thread that is located between line ball 3121 and stainless steel strip 330 properly.

The above embodiments are provided to further explain the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above embodiments are only examples of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
