Method for continuous pressure welding and the rotary sonotrode for the continuous ultrasonic pressure welding of thin thermoplastic films

摘要

a continuous thin film ultrasonic welding of thermoplastic is that sealed material placed between rotating anvil and rotating sonotrodu0105 with emphasis on material welded, pushing firmly to the anvil, and the surface roboc for sonotrody (1) contacted with the welded material (2,3).it's twitching orifice in the direction of movement (e) parallel to the axis of rotation sonotrody (1).sonotroda rotary continuous welding ultrasonic thin film is a thermoplastic alloy rotary light and length sonotrody (1), measured along its axis of rotation, is less by at least 20% from the value? / 2, forehead sonotrody (1) is flat.a working surface sonotrody (1) in the axial view creates sonotrody working surface (1) at least one annular strengthening and dimples.
