Description

Technical Field

[0001] The utility model relates to the technical field of plastic welding equipment, in particular to an ultrasonic welding machine. Background Art

[0002] The principle of ultrasonic welding machine is that the generator generates high-voltage, high-frequency (common frequencies are 35KHz, 20KHz, 15KHz) signals, and converts the signals into high-frequency mechanical vibrations through the transducer system. The signals are applied to the plastic workpiece, and the temperature transmitted to the interface is increased through the friction between the workpiece surface and the molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface melts rapidly and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure to achieve the welding purpose.

Some of the installed lifting structures use guide rods and linear bearings for transmission, which have poor impact load capacity and small load-bearing capacity.
