Then the outer end of the fiber cloth is fixed on the winding roller 15, and the motor 16 is turned on to drive the winding roller 15 to rotate. At the same time, the electrode column 7 is connected to the external power supply, so that the electric heating wire 11 is energized to generate high temperature to cut the fiber cloth along the length of the fiber cloth. After the cutting, the fiber cloth is rolled up by the winding roller 15. During the winding process, the winding roller 15 can pull the fiber cloth to continue to move, so as to realize the continuous cutting of the fiber cloth. When a roll of fiber cloth is cut, the user re-sets the fiber cloth sleeve to be cut on the unwinding shaft 3, and repeats the above steps to cut the fiber cloth sleeve, thereby avoiding the problem that the existing cutting device needs to frequently replace the cutter head during use, resulting in frequent equipment shutdown and affecting production efficiency.
