Ultrasonic cutting machine is a kind of ultrasonic equipment specially used for cutting, and it is one of the important categories of ultrasonic applications.

The principle is completely different from traditional cutting. The ultrasonic cutting machine uses the energy of ultrasonic waves to heat and melt a part of the material to be cut, so as to achieve the purpose of cutting the material. Ultrasonic cutting machine features, does not need sharp cutting knife, does not need a lot of pressure, and will not damage the cutting material. The cutting knife is doing ultrasonic vibration, the friction resistance is very small, and the material to be cut is not easy to stick to the blade. It has obvious cutting effect on frozen, viscous and elastic materials. It is especially effective for cutting food, rubber or objects that are inconvenient to apply pressure. At the same time of cutting, the cutting part has fusion. Sealing the cutting part can prevent the loosening of the cut material (such as textile material flash). The use of the ultrasonic cutting machine can also be expanded, such as digging holes, shoveling, scraping paint, carving, slitting, etc. The basic composition of the sonic cutting machine. Ultrasonic transducer, ultrasonic horn, ultrasonic cutting knife, ultrasonic generator.

The ordinary current of the ultrasonic generator is converted into a high frequency and high voltage alternating current, which is output to the ultrasonic transducer. Ultrasonic transducer is equivalent to energy conversion device, it can convert the input electric energy into mechanical energy, namely ultrasonic wave. The ultrasonic transducer stretches back and forth in the longitudinal direction, and the frequency of the stretch movement is equal to the frequency of the high-frequency alternating current supplied by the driving power source. Ultrasonic horn The ultrasonic horn amplifies the output amplitude of the ultrasonic transducer. The ultrasonic cutter further amplifies the amplitude and focuses the ultrasound. Ultrasonic waves are output, and the cutting knife is used to concentrate the ultrasonic energy into the cutting part of the material to be cut. Under the action of huge ultrasonic energy, this part instantly softens and melts, and its strength is greatly reduced. Only a small amount of force is required to achieve the purpose of cutting materials.

According to the cutting method of ultrasonic cutting machine, it can be divided into: knife cutting machine and anvil cutting machine. The two cutting methods are suitable for different process conditions and cutting objects. Application fields of ultrasonic cutting machine: Ultrasonic cutter cutting machine is suitable for cutting thick, thick, long and other materials that are not convenient to set up anvils. Such as the raw rubber output from the rubber mixing machine, pipe cutting, frozen meat, candy, chocolate cutting, printed circuit board, or hand-held cutting machine, etc. In order to meet the needs of embossing and cutting, adding a cylindrical flower wheel on the cutting chopping board can cut endless patterns and patterns with low cost and high efficiency. This cutting method is suitable for cutting thin materials, such as all kinds of trademarks, clothing lace, cloth cutting, decorative bead cutting, natural fiber, synthetic fiber, non-woven fabric, man-made resin, paper, film cutting, slitting and so on.
