30Khz Ultrasonic Portable Non-woven Fabric Cutting and Sealing Knife with Digital Generator

Description:

The principle of an ultrasonic rubber cutter is to convert a 50/60 Hz current into 20, 30 or 40 kHz of electrical energy by means of an ultrasonic generator. The converted high-frequency electrical energy is again converted by the transducer into mechanical vibration of the same frequency, and then the mechanical vibration is transmitted to the cutting blade through a set of amplitude modulator devices that can change the amplitude. The ultrasonic rubber cutting blade vibrates along its length with an amplitude of 10-70 μm and repeats 40,000 times per second (40 kHz) (the vibration of the blade is microscopic and generally difficult to see by the naked eye). The cutting blade then transmits the received vibration energy to the cutting surface of the workpiece to be cut, in which the vibration energy is cut by activating the molecular energy of the rubber molecule and opening the molecular chain.

Advantage:

The characteristics of the ultrasonic cutting machine do not require sharp edges, do not require a lot of pressure, and will not cause chipping or breakage of the cutting material.

The cutting blade is subjected to ultrasonic vibration, and the frictional resistance is particularly small, and the material to be cut is not easily adhered to the blade. The cutting effect on frozen, viscous and elastic materials is obvious. It is especially effective for cutting food, rubber or inconvenient objects.

At the same time of cutting, the cutting portion has a fusion. The cutting site is perfectly sealed to prevent loose tissue (such as textile material flash). The use of ultrasonic cutting machines can also be extended, such as digging holes, shovel digging, scraping paint, engraving, slitting, etc.

Distinguishing traditional cutting:

Ultrasonic cutting machine is a device that uses wave energy to cut and process. The biggest feature is that it does not use traditional cutting edge.

Conventional cutting uses a sharp-edged tool to press against the material being cut. The pressure is concentrated at the cutting edge, the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bonding of the material is pulled apart and cut. Since the material is pulled hard by the strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must withstand relatively high pressure. It is not good for soft and elastic materials, and it is more difficult for viscous materials.
