The principle of ultrasonic cutting machine:
Ultrasonic cutting machine uses the energy of ultrasonic wave to locally heat and melt the material to be cut to achieve the purpose of cutting material. The principle of the ultrasonic cutting machine is completely different from the traditional cutting.
Traditional cutting machine:
Use a knife with a sharp edge to press against the material being cut. This pressure is concentrated at the edge of the blade, and the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bond of the material is pulled apart and cut off.
Because the material is pulled apart by strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must withstand relatively large pressure. It is not good for cutting soft and elastic materials, and it is more difficult for sticky materials.
Ultrasonic food cutting machine:
Ultrasonic cutting machine is a type of equipment that uses wave energy for cutting. Ultrasonic cutting does not require a sharp cutting edge, nor does it require a lot of pressure, and will not cause chipping or damage of the material being cut.
Because the cutting blade is doing ultrasonic vibration, the friction resistance is particularly small, and the material to be cut is not easy to stick to the blade. This is especially effective for cutting viscous and elastic materials, frozen materials such as food, rubber, etc., or objects that are inconvenient to apply pressure.
Composition of ultrasonic food cutting machine:
The ultrasonic cutting machine is composed of an ultrasonic transducer, an ultrasonic horn, an ultrasonic cutter, and an ultrasonic generator.
Ultrasonic generator: Mains power is converted into high-frequency, high-voltage AC current, which is transmitted to the ultrasonic transducer. Ultrasonic transducer is equivalent to energy conversion device, it can convert the input electrical energy into mechanical energy, that is, ultrasonic. The ultrasonic transducer performs telescopic movement back and forth in the longitudinal direction, and the frequency of the telescopic movement is equal to the frequency of the high-frequency alternating current supplied by the driving power supply.
Ultrasonic horn: The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer.
Ultrasonic cutter: further amplify the amplitude and focus the ultrasound.
Ultrasound is output, and the ultrasonic energy is concentrated and input to the cutting site of the material to be cut using a cutter. Under the action of huge ultrasonic energy, this part instantly softens and melts, and its strength drops greatly. Only a small force is needed to achieve the purpose of cutting materials.
classification
According to the ultrasonic cutting machine, the cutting method can be divided into: cutter cutting machine and cutting board cutting machine. The two cutting methods are suitable for different process conditions and cutting objects.
Ultrasonic cutter cutting machine:
The ultrasonic energy is directly loaded on the cutter, and the cutter becomes a cutter with ultrasound. When cutting the material, the material is mainly softened and melted by the ultrasonic energy, and the cutting edge of the cutter is only used for cutting seam positioning, ultrasonic energy output, and separating materials. This cutting method is suitable for cutting materials that are inconvenient to set the cutting board, such as thick, thick and long. Such as raw rubber cutting, tube cutting, frozen meat, candy, chocolate cutting, printed circuit board, or handheld cutting machine output from the rubber mixer.
Ultrasonic cutting board cutting machine:
The basic structure is similar to the ultrasonic cutter cutting machine. The ultrasonic output part is not a cutting knife, but a standard ultrasonic flat mold. The mold is equivalent to a chopping board that is performing ultrasonic vibration. The cutting knife can still be used in any traditional shape, but the sharpness of the cutting edge is reduced, and the life of the cutting knife is greatly extended.
