AI Technical Summary

Problems solved by technology

The objective existence is that the above-mentioned ultrasonic welding device is only suitable for the welding of non-woven fabrics with less than 4 layers, and is not suitable for the welding of non-woven fabrics with more than 4 layers, especially on production lines with a speed of more than 120 meters per minute. The quality does not meet the tensile strength of the international industry standard, and all the products welded by the production line are scrapped
