Ultrasonic Cutting Machine Fast Speed, High Efficiency, No Pollution

Ultrasonic cutting is the use of ultrasonic energy to locally heat and melt the material being cut to achieve the purpose of cutting the material. It can easily cut resin, rubber, non-woven fabric, film, various overlapping composite materials and food. The principle of the ultrasonic cutting machine is completely different from the traditional pressure cutting.

1. Problems with rubber cutting


The traditional rubber cutting technology needs to lubricate the rubber during cutting, and there are phenomena such as slow cutting speed, large cuts, a large amount of dust, broken surfaces, sticky knives, etc. Many companies are still using traditional manual methods for cutting, which not only can not meet the productivity but also brings hidden dangers to life safety.


For rubber products, cold cutting is more suitable than thermal cutting. Cold cutting has the advantages of low heat generation, small thermal deformation, less dust during cutting, and no aging cracks due to excessive temperature. Ultrasonic rubber cutting technology belongs to cold cutting, which uses ultrasonic energy to locally heat and melt the cut rubber to achieve the purpose of cutting materials.



2. Principle:


Ultrasonic rubber cutting blades use the energy of sound waves to cut, without the need for sharp edges or great pressure, and will not cause chipping or damage of the material being cut. Ultrasonic rubber cutter can easily cut resin, rubber, non-woven fabric, film, various overlapping composite materials and food.


The principle of ultrasonic rubber cutter is to convert 50/60Hz electric current into 20, 30 or 40kHz electric energy by ultrasonic generator. The converted high-frequency electrical energy is converted into mechanical vibration of the same frequency again through the transducer, 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 (40 kHz) per second (the vibration of its blade is microscopic, which is generally difficult to see with the naked eye). The cutter then transmits the received vibration energy to the cutting surface of the workpiece to be cut. In this area, the vibration energy is used to cut the rubber by activating the rubber molecular energy and opening the molecular chain.
