40Khz High Efficiency Ultrasonic Cutting And Sealing Machine For Nonwoven Welding

High efficiency ultrasonic cutting and sealing machine for nonwoven welding

Parameter

Description

With ultrasonic sealing, the heat required for melting is only generated inside the thermoplastic sealing layer. For localized conversion of vibrations to friction heat, the anvil or sonotrode profiles are mostly linear. These profiles ensure focusing of the energy input and therefore short sealing times between 100 and 200 milliseconds. With ultrasonic sealing heat is generated at the inside of the film, not by heat input from the outside as is the case with heat sealing, for example. The tools (sonotrode and anvil) that come into direct contact with the packaging material, remain cold during the entire weld process. The support layer remains almost cold and upon termination of energy input, the heat dissipates faster to the outside due to the temperature difference between the support layer and the sealing layer so that the hot-tack resistance is significantly higher.

The applicable materials of ultrasonic wave sealing and cutting include: 100% of synthetic fiber, such as nylon, polyester, polypropylene, some polyethylene, modified acrylic resin, vinyl compounds, carbamate compounds, thin films, coated paper, etc. It also includes synthetic fibre mixing 35 to 50% of synthetic fiber composition.Ultrasonic can cut and sew at the same time, preventing the knitted or textile materials to be off-line. It has slot edge taper avoiding pilling. The application includes cutting, carpet ornaments, clothing labels, curtains, cable materials and industrial woven belt etc..

The mechanical vibration energy generated by the ultrasonic generator exceeds 20,000 blade vibrations per second, which will heat and melt the part of the cutting material, causing the molecular chain to break apart rapidly, thus achieving the purpose of cutting the material.Therefore, ultrasonic cutting does not require a particularly sharp blade, nor does it require a lot of pressure, which will not cause breakage and breakage of the cutting material.At the same time, due to the ultrasonic vibration cutting knife, friction is small, by reducing the material is not easy to adhere to the blade.Viscous and elastic materials, frozen, such as food, rubber, etc, or inconvenient to add pressure to cut objects, are especially effective.

The advantage of ultrasonic cutting is that it has a fusion effect on the cutting site at the same time.The cutting part is perfectly hemmed to prevent loose organization of the cutting material (such as the flying edge of textile material).The use of ultrasonic cutters can be extended, such as hole digging, shoveling, painting, carving, slitting and so on.
