Ultrasonic generator, usually called ultrasonic electric box, ultrasonic generating source, ultrasonic power supply. Its function is to convert our mains (220V or 380V, 50Hz or 60Hz) into a high-frequency alternating current signal that matches the ultrasonic transducer. From the form of amplifying circuit, linear amplifier circuit and switching power supply circuit can be used, and high-power ultrasonic power supply generally adopts the circuit form of switching power supply from the perspective of conversion efficiency. The linear power supply also has its unique application range. Its advantage is that the circuit matching is not strictly required, and the operating frequency is allowed to change continuously and rapidly. The device can be used for fast cutting without the need for sharp blades and pressure, preventing edge collapse of the material to be cut and accidental injury of the operator, etc., and improving the traditional cutting process.

The ultrasonic horn is an important part of the ultrasonic vibration system. Its main function in the vibration system is to amplify the particle displacement or velocity of the mechanical vibration, change the amplitude and frequency, and concentrate the ultrasonic energy on a small area. That is to gather energy, so it is also called ultrasonic gear lever or ultrasonic concentrator. The amplitude frequency can be changed according to the thickness and material of the material being cut.

Ultrasonic cutter: It is to load ultrasonic waves on the cutting tool, so that the tool generates ultrasonic vibration and has the effect of cutting. Ultrasonic cutter 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.

Four-axis linkage device: The four-axis linkage transmission mechanism can perform motion cutting along the X-axis, Y-axis, Z-axis and rotation along the Z-axis. The four-axis high degree of freedom is used to form an integrated structure of the line and the whole machine, which can realize the rapid cutting operation of various varieties and specifications, and can be used for single machine operation or connected production.

The technical indicators of this device:

1) Power supply: AC220V-230V 50HZ;

2) Equipment power of the whole machine: 3.6KW (of which the power of the ultrasonic generator is adjustable from 0.2-1.2KW);

3) Frequency: 19.4KHZ-20.5KHZ;

4) Cutter size: 150-350mm;

5) Cutting speed: 15-45 times/min (adjustable);

6) Movement direction: four axes.

Further, the length of the cutter 4 is not less than the width of the material 3 to be cut.

Further, one end of the frame 1 is provided with a motor 9 for driving the conveyor belt 2 to move.

Further, the width of the upper portion of the blade 42 is greater than the thickness of the blade 42 .

The use process of the present invention is as follows:

1. When the conveyor belt 2 conveys the material 3 to be cut to the infrared sensing area, the conveyor belt 2 stops conveying after the infrared signal is received (the conveying direction of the conveyor belt 2 is the X direction);

2. The cutter assembly 5 is adjusted to the X-axis direction, and the cutter assembly 5 is moved up and down along the Z-axis direction by the lifting motor 11 to cut the material 3 to be cut. The cutter assembly 5 is slightly raised upward by a distance of 5mm, and then the cutter The combination 5 moves 10mm in the Y-axis direction, and the cut materials are separated by an effective distance; the cutter combination 5 is raised along the Z-axis direction, so that the cutter leaves the surface of the material 3 to be cut, and the cutter combination 5 Continue to move in the Y-axis direction to cut the material to be cut 3;

3. After cutting in the Y direction, the cutter combination 5 returns to the original position, and the cutter combination 5 rotates 90° around the Z-axis direction to adjust the direction of the cutter 4;

In steps 2 and 3, during the cutting process of the cutter combination 5, the ultrasonic generator 52 is started, and the ultrasonic generator 52 drives the tool holder 51 to generate ultrasonic vibration through the ultrasonic energy conversion horn 53; at the same time, the oil supply pump stops supplying oil, The blade 42 is resisted by the material to be cut 3, the upper part of the blade 42 moves to the side of the oil leakage channel 43, and the edible oil stored in the oil storage cavity 44 flows out along the slit between the blade 42 and the material to be cut 3, Oil film protection is formed on the surface of the material to be cut 3;

5. The cutter assembly 5 is restored to the original position and the conveyor belt 2 starts to run. The upper part of the blade 42 is affected by its own weight and oil pressure, and the gap between the blade 42 and the blade seat 41 is re-sealed. The oil supply pump works, and the oil storage chamber 44 Fill with cooking oil and repeat steps 1~5 above.
