超声波塑料焊接机的工作原理
Working principle of ultrasonic plastic welding machine
超声波焊接原理是通过超声波发生器将50/60赫兹电流转换成15、20、30或40千赫兹电能。被转换的高频电能通过换能器再次被转换成为同等频率的机械运动,随后机械运动通过一套可以改变振幅的调幅器装置传递到焊头。
The principle of ultrasonic welding is to convert 50 / 60 Hz current into 15, 20, 30 or 40 kHz electric energy through ultrasonic generator. The converted high-frequency electric energy is converted into mechanical motion of the same frequency again through the transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator device which can change the amplitude.
焊头将接收到的振动能量传递到待焊接工件的接合部,在该区域,振动能量被通过摩擦方式转换成热能,将塑料熔化。超声波不仅可以被用来焊接硬热塑性塑料,还可以加工织物和薄膜。一套超声波焊接系统的主要组件包括超声波发生器,换能器/调幅器/焊头三联组,模具和机架。
The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction, which melts the plastic. Ultrasonic can be used not only to weld hard thermoplastic, but also to process fabrics and films. The main components of a set of ultrasonic welding system include ultrasonic generator, transducer / amplitude modulator / welding head triple group, mold and frame.
