Meanwhile, the second godet wheel is used as an angle forming point, and the angle formed among the first godet wheel, the second godet wheel and the driving wheel is preferably 90-135 ℃, because the second godet wheel is used as the angle forming point, if the angles of the first godet wheel, the second godet wheel and the driving wheel are smaller than 90 or larger than 135, the metal wire cannot be effectively straightened, and the service life of the straight copper tube is influenced. Of course, the technical scheme can also be provided with 2 godet wheels, and 2 straight copper pipes are arranged among the 2 godet wheels; it is also possible to provide 3 or more godet wheels and to arrange at least 1 straight copper tube between every 2 godet wheels.
