Abstract: A control method of an ultrasonic welding system comprises: detecting operation of the ultrasonic welding system immediately while the ultrasonic welding system is in a working state; acquiring a current working frequency of an ultrasonic generator in the ultrasonic welding system while the ultrasonic welding system is detected to complete a preset first operation every time; determining a current frequency searching range of the ultrasonic generator according to the current working frequency of the ultrasonic generator; controlling the ultrasonic generator to search for an anti-resonance point in the current frequency searching range; and adjusting the working frequency of the ultrasonic generator to be an anti-resonance point while the anti-resonance point is searched in the current frequency searching range.

Abstract: A cutter head structure includes a cutting edge portion including a cutting body. An outer surface of the cutting body is a curved surface which protrudes forwardly. The outer surface of the cutting body is provided with a first cutting edge and at least two second cutting edges. The first cutting edge extends from one side of the cutting body to a top region of the cutting body and then to the other side of the cutting body. The second cutting edges are respectively disposed on both sides of the first cutting edge. First chip flutes are defined between the first cutting edge and the second cutting edges adjacent thereto, and each of the first chip flutes has a width gradually increasing from the top region to both ends of the cutting body.
