How does the ultrasonic multifunction food cutting machine cut?

How does the ultrasonic multifunction food cutting machine cut?

1. Principle of ultrasonic cutting

The principle of ultrasonic multifunction food cutting machine is completely different from traditional cutting. The principle of ultrasonic cutting is to convert 50/60Hz current into 20, 30 or 40KHz electrical energy through an ultrasonic generator. It is converted into mechanical vibration of the same frequency, and then the mechanical vibration is transmitted to the cutting knife through a set of amplitude modulator devices that can change the amplitude. The cutting knife transmits the received vibration energy to the cutting surface of the workpiece to be cut, and in this area, the vibration energy is used to cut the rubber material by activating the rubber molecular energy and opening the molecular chain. This is especially effective for cutting sticky and elastic materials, frozen materials such as food, rubber, etc., or objects that are inconvenient to press. Another great advantage of ultrasonic cutting is that it has a fusion effect on the cutting part while cutting. The cutting area is perfectly edged to prevent the loosening of the material being cut (eg, flashing of textile materials). The use of ultrasonic cutting machine can also be extended, such as digging holes, shovel digging, scraping paint, engraving, slitting and so on.

​​2. The basic structure and characteristics of ultrasonic cutting

Ultrasonic multifunction food cutting machine is a type of equipment that uses wave energy for cutting. Its biggest feature is that cutting does not require cutting edges. In other words, no cutting edge in the traditional sense. Traditional cutting is to use a knife with a sharp edge to press against the material to be cut. This pressure is concentrated at the cutting edge, and the pressure is very large, which exceeds the shear strength of the material to be cut, and the molecular bonds of the material are pulled apart and cut off. Since the material is pulled apart by strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must bear a relatively large pressure. The cutting effect is not good for soft and elastic materials, and it is more difficult for sticky materials.

The basic composition is an ultrasonic transducer, a horn, a cutting knife (tool head), and a driving power supply. The ultrasonic driving power supply converts the mains power into high-frequency high-voltage alternating current and outputs it to the ultrasonic transducer. The ultrasonic transducer is actually equivalent to an energy conversion device, which can convert the input electrical energy into mechanical energy, that is, ultrasonic waves. Its manifestation is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic motion is equal to the frequency of the high-frequency alternating current supplied by the driving power supply. The function of the horn is to fix the entire ultrasonic vibration system, and the second is to amplify the output amplitude of the transducer. The cutting knife (tool head) on the one hand further amplifies the amplitude and focuses the ultrasound. On the other hand, it outputs ultrasonic waves, using the similar cutting edge of the cutting knife to concentrate the ultrasonic energy into the cutting part of the material to be cut. Under the action of huge ultrasonic energy, this part is instantly softened and melted, and the strength is greatly reduced. At this time, as long as a small cutting force is applied, the purpose of cutting the material can be achieved. Similar to conventional cutting, the basic components required are cutters and cutting boards, and ultrasonic cutting machines also have two basic structures.

Depending on where the ultrasonic wave is applied, we might as well divide it into an ultrasonic knife-type cutting machine and an ultrasonic chopping board-type cutting machine. Ultrasonic multifunction food cutting machine directly loads ultrasonic energy onto the cutter, and the cutter becomes a cutter with ultrasonic waves. When cutting materials, the materials are mainly softened and melted by ultrasonic energy, and the cutting edge of the cutter only plays the role of kerf positioning, ultrasonic energy output, and separation of materials. This cutting method is suitable for cutting thick, thick, long and other materials that are inconvenient to set a cutting board. Ultrasonic multifunction food cutting machine is suitable for: raw rubber cutting, pipe cutting, frozen meat, candy, chocolate cutting, etc.
