Ultrasonic hand-held machine is a kind of ultrasonic ultrasonic cutting machine welding machine. Usually used for plastic welding. It completely replaced the traditional rubber industry. Ultrasonic welding process without bolts, nails, snap ring, welding material or adhesive. It is quicker than the traditional adhesive or glue, drying time and faster. Welding process is easy to implement. Automatic, easy to customize. Ultrasonic plastic welding machine has a variety of welding methods, such as welding, riveting, welding, etc.
Principle of ultrasonic hand-held welding machine
When the ultrasonic wave applied to thermoplastic interface, high frequency vibration will produce tens of thousands of times per second. The high frequency vibration reaches a certain amplitude. Ultrasonic energy through the upper weldment is passed to the welding area. Due to the welding area (i.e., the interface between the two weld) of acoustic resistance is higher, can produce local high temperature. Due to poor thermal conductivity ultrasonic generator driver of plastic, can't timely distribution and gathered in welding area, result in two kinds of plastic contact rapidly melting, coupled with a certain pressure, make them together. When the ultrasonic wave to stop working, let the pressure for a few seconds, make its solidification and forming solid molecular chain, so as to achieve the purpose of the welding, welding strength can be close to the strength of the raw materials. Depends on the quality of ultrasonic plastic welding welding joint, amplitude of the pressure and welding time.
Adjustable welding time and welding pressure, amplitude is determined by the sensor and the horn. The interaction of these three quantity has an appropriate value. When more energy than a certain value, the volume of plastic melt of welding material easy to deformation. If energy is very small, it is not easy to weld, pressure is not too big. The stress is pressure welding parts per mm edge length and the edge of the ultrasonic metal welding product.
Ultrasonic welding machine is usually used for plastic welding. It completely replaced the traditional rubber industry. No bolts, nails, ultrasonic welding process card buckle, welding material or adhesive. It faster than the traditional adhesive or glue, and the drying time is soon. The welding process can be completed. Easy to realize automation, easy to customize, so as to adapt to welding products of various specifications.
