Description

Technical Field

[0001] This utility model relates to the technical field of disposable hygiene product production equipment, specifically to a split swing arm for ultrasonic flip welding equipment. Background Technology

[0002] Currently, in domestic disposable hygiene product equipment, especially pull-up trouser machinery, waistband welding is an important standard for product quality and one of the factors affecting machine start-up speed. Ultrasonic flip welding devices are commonly used to weld the waistbands, such as the pull-up trouser ultrasonic flip welding device with authorization announcement number CN112873865B, to better ensure stable welding position and welding effect. However, the swing arm on the existing ultrasonic flip welding device is usually machined as a whole, which is inconvenient to manufacture. It is usually made of iron, which is heavy and increases the inertia of the swing arm during flipping, increasing the load on the drive motor. This is not user-friendly and does not help the flexibility of the swing arm flipping action. When the swing arm is damaged, it is inconvenient to repair and the entire swing arm needs to be replaced, resulting in high repair costs. In addition, it is also inconvenient to assemble the airbag in the swing arm. Utility Model Content
