The ultrasonic transducer conducts ultrasonic waves to the plastic processing parts through the welding head, so that the two plastic joints are subjected to ultrasonic waves to produce violent friction, and the friction heat melts the plastic joints to complete the gluing. This technology has the advantages of fast speed and firm welding seams, and more importantly, it can automate the production and processing of plastic products. Ultrasonic plastic welding machine can perform plastic welding, embedding, forming, riveting, spot welding, cutting, sewing and other operations. As long as the welding head is changed, one machine can be used for multiple applications.
Ultrasonic transducer composition:1. Middle piezoelectric ceramic element 2. Front and rear metal cover 3. Prestressed screw 4. Electrode sheet 5. Insulating tube
This kind of sandwich transducer generates stable ultrasonic waves when the load changes, which is a relatively basic and main method to obtain a power ultrasonic drive source.
According to different designs, the main forms of ultrasonic transducers are:
1. Column type 2. Inverted horn type 3 Steel back cover type 4. Intermediate aluminum sheet type
Technical features:The piezoelectric ceramic chip adopts original imported parts to ensure strong and stable ultrasonic power output;
High efficiency: high mechanical quality factor, working at the resonance frequency point can obtain extremely high electro-acoustic conversion efficiency;
Large amplitude: The structure optimized by computer has high vibration speed ratio and large amplitude of the front cover;
High power: under the action of the prestressed screw, the energy of piezoelectric ceramics can be exerted to the greatest extent;
Good heat resistance: low resonance impedance, low heat generation, and wide operating temperature range.
Our company specializes in the production of ultrasonic welding transducers. This product has high performance, long life, and good welding effect. The ultrasonic used in plastic processing, the existing working frequencies are 15KHZ, 18KHZ, 20KHZ, 40KHZ. The principle is to use the peak position of the longitudinal wave to transmit the amplitude to the gap of the plastic part. Under pressure, the two plastics The molecules in the contact parts of the parts or other parts and the plastic parts collide with each other to melt, so that the plastic in the contact position is fused, and the processing purpose is achieved.
Ultrasonic welding transducer for the ultrasonic processing of thermoplastic glue uses the high-frequency friction between the working joints to rapidly generate heat between molecules. When this heat is enough to melt the work, the ultrasonic vibration is stopped. At this time, the working joint The noodles are melted and solidified to complete the processing procedure. The frequencies usually used for plastic processing are 20KHZ and 15KHZ, and their frequencies are outside of human hearing, so they are called ultrasonic waves. Ultrasonic welding machines should be used in the electronics industry, stationery industry, transportation equipment, toys, cosmetics, motors and other materials such as PP, PE, ABS, and acrylic.
