A sewing thread feeding device. [Prior Art] Φ The general sewing machine is a simple sewing operation. In the past, the sewing thread was wound around a rotatable cylinder. In addition to the need to manually pull the cloth, the sewing staff also needed to pull the sewing thread by itself, which required time-consuming and laborious work. In addition to the frequent work safety accidents, it also affects the precision of sewing products. With the development of technology, automated systems can provide better products, so automatic cloth pulling devices and sewing thread feeding devices have been developed. The workflow can be standardized. _ Please refer to the first figure, which is a perspective view of a conventional sewing thread feeding device, which mainly includes: a sewing thread winding rod 11', a fixed pressing wheel 12, a motor 13', a movement a wheel 14', and a clamping rod 15, wherein the motor 13' is disposed in the fixed pressing wheel 12', and can drive the fixed pressing wheel 12 to rotate, and the cooling rod 15' can be controlled Whether the moving pressure roller 14' touches the fixed pressure roller 12'; the sewing thread is always wound around the sewing thread winding rod 11, and passes between the fixed pressure roller 12' and the moving pressure roller 14' Then, by the fixed pressure roller 12, and the moving pressure roller 14' are clamped and rotated, the clamping action controls the tension of the sewing thread, and the rotation system allows the sewing thread to be fed to the sewing machine initial end. 3 M418930 However, the conventional sewing thread feeding device has the following inconveniences in use. (1) Sewing thread tension and conveying speed cannot be controlled separately: When the fixed pressing wheel 12' and the moving pressing wheel 14' rotate slowly The tension of the sewing thread will increase, and the conveying speed will be slow.
