Precautions For Welding Head Movement Of Ultrasonic Plastic Welding Machine

Precautions for welding head movement of ultrasonic plastic welder is composed of ultrasonic generator, welding head, mold and electrical system. Its working principle is that the ultrasonic generator generates ultrasonic wave and sends it through the welding head. The ultrasonic energy is absorbed by the surface of the welded object and converted into heat energy. At the same time, the ultrasonic plastic welding opportunity generates certain mechanical stress on the welded object, Make it fuse more fully. In the process of equipment welding, the movement of welding head is very important.

The welding head of ultrasonic plastic welder machine needs two mechanical movements: reversing and lifting. People should pay attention to skills when operating the welding head. When the stop position of the welding head after turning is incorrect or not in place, the meshing process between the gears of the equipment will not be able to proceed normally, resulting in wrong teeth or oblique travel of the welding wheel. Therefore, attention must be paid to the accuracy of the position. In general, the correct reversing movement of the welding head of the ultra sonic plastic welding machine can ensure that the gear, spline pair and other components do not have abnormal wear, and the accuracy of the lifting of the welding head and the rolling of the welding wheel can be guaranteed. During the lifting movement of the welding head, pay attention to adjust the pre compression shrinkage of the return spring and reasonably give the air pressure of the piston to ensure that the lifting position can accurately stay at the predetermined position, otherwise there will be the problem of false welding or crushing of the welded object.

The ultrasound plastic welding machines on the market are basically semi-automatic equipment. People control the welding work of the welding head by setting control parameters. Therefore, whether the welding head is reversed or lifted, the corresponding parameters should be set reasonably, and the accuracy of the parameters should be ensured through the welding test. With a long welding time, the welding head may become loose due to vibration and other reasons, resulting in abnormal reversing and lifting movement of the welding head, affecting the welding quality. Therefore, the welding workers should always pay attention to the welding condition of the ultrasonic plastic welding equipment. Once any abnormality is found, they should stop the machine immediately and adjust the welding head before continuing to work.
