Firstly, the ultrasonic lace machine divides its working frequency into different levels based on the vibration frequency of sound waves. If the frequency is not adjusted properly when replacing the fabric, it can easily lead to the failure of the welding interface.

Secondly, the pressure of the welding joint is also an important factor affecting the welding quality. If the assistant adjusts the pressure of the welding joint insufficiently, it can also lead to the failure of the welding interface.

Finally, during the use of ultrasonic lace machines, each machine has its own specific welding parameters. When replacing different types of fabrics, it is necessary to reset the machine parameters, including welding power, pressure, etc. If not set according to the requirements, it is easy to cause welding failure.

In order to effectively avoid the occurrence of the above problems, it is necessary to strengthen the technical training of employees, establish correct and standardized operating procedures, and maintain the machine in a timely manner to ensure the smooth progress of the production process. At the same time, further optimizing the performance of ultrasonic lace machines and improving their intelligence is also the direction of technological innovation. In this way, it provides favorable guarantees for manufacturers to improve production efficiency, reduce production costs, and create high-quality, efficient, and environmentally friendly production and manufacturing processes.
