Starching machine capable of adjusting pressure and tension of yarn in real time

The invention discloses a starching machine capable of adjusting the pressure and tension of yarn in real time. The starching machine comprises a base. A working cavity is formed in the upper end faceof the base. Power spline shafts are arranged at the left side and the right side inside the working cavity in a rotatable manner. Power rotating parts are in spline connection to outer circumferential faces of the power spline shafts at the left side and the right side in a vertically-symmetrical manner. A bevel gear box is fixedly connected to the outer circumferential faces of each power rotating part. Material barrels are arranged at the upper side and the lower side in the working cavity in a symmetrically and rotatable manner. A rotating shaft is connected to the center of the end, close to the corresponding material barrel, of each bevel gear box at the left side or the right side in a rotary manner. According to the starching machine, the mode that the pressure and tension of starching edges of the yarn a
