1. A tensioning device comprising:

  • a float member for adjusting tension of the web by applying force to the web;

    a support unit supporting the web at a fixed position; and

    a first connecting rod, an inclined connecting rod and a second connecting rod, wherein the first connecting rod and the inclined connecting rod are respectively hinged with two transverse ends of the floating piece along the width direction of the web material, the second connecting rod is hinged with the inclined connecting rod,wherein the float member includes a first ultrasonic vibrator that generates ultrasonic vibration and applies a force to the web in a non-contact manner by applying a repulsive force caused by the ultrasonic vibration to the web without contacting the web,the supporting unit includes a second ultrasonic vibrator,the first ultrasonic vibrator applies a repulsive force to a first surface of the web, the second ultrasonic vibrator generates ultrasonic vibrations and applies a repulsive force caused by the ultrasonic vibrations of the second ultrasonic vibrator to a second surface which is a rear surface of the first surface, thereby supporting the web in a non-contact manner,wherein one end of the first connecting rod is hinged with the floating piece, the other end of the first connecting rod is connected with the piston of the first cylinder,one end of the tilting link is articulated with the float, anOne end of the second connecting rod is hinged with the other end of the inclined connecting rod, and the other end of the second connecting rod is connected with the piston of the second cylinder.
