Description

Technical Field

[0001] The utility model relates to the technical field of clothing production, in particular to an ultrasonic floating cloth pressing mechanism. Background Art

[0002] In the clothing production industry, ultrasonic bonding is a common fabric splicing process. During the processing, the thickness of the fabric splicing position varies according to the position of the fabric seam. This causes the fabric pressing wheel to fluctuate up and down with the thickness of the fabric during ultrasonic bonding. The pressing wheel and ultrasonic cutter in the existing mechanism are locked on a motion mechanism, which limits the thickness of the cut cloth. If the fabric is too thick or has convex parts, the cutter will rise as the pressing wheel rises, resulting in the inability to cut thick fabrics or thick fabrics. There are high requirements for fabrics and cutting edges, which greatly limits the versatility of ultrasonic splicing equipment.
