Heat-sealing transmission mechanism and air cushion machine

Abstract

Disclosed are heat-sealing transmission mechanism and air cushion machine. The heat-sealing transmission mechanism includes a wheel body and heating elements wound around the outer circumference of the wheel body. Gaps are formed between two bent corners of the heating elements. The gaps of at least two heating elements are circumferentially staggered on an axial projection plane of the wheel body. The air cushion machine includes a driving component and the heat-sealing transmission mechanism. The heating elements form at least two heat-sealing lines on the film ply. The two bent corners of the heating elements form a pair of heat-sealing trailing ends which share extrusion pressure exerted by the gas in the inflatable chamber, thereby minimizing the likelihood of poor sealing at the heat-sealing trailing ends. Sealed gas leaking through the gap between the pair of heat-sealing trailing ends near inflatable chamber is blocked by at least one heat-sealing line.
