Abstract

Disclosed is a buffering air cushion machine, wherein the angle between a heat-sealing cooling transmission module as a core component of the buffering air cushion machine and a horizontal plane is between 20-50 degrees, thus greatly decreasing the transverse dimension of the buffering air cushion machine, so as to decrease the size of the whole machine and decrease the space occupied by the buffering air cushion machine; an inflation guide rod of a bent type may release some tension on a sealing side (an inflating passage) of a air cushion film, and may prevent wrinkles and bends from forming on the sealing side of the air cushion film during heat-sealing, so as to improve the quality of heat-sealing; furthermore, an upper coiling film guide rod and a lower coiling film guide rod may block the inflating passage connecting two air cushion films, and may prevent the air in the air cushion film which is filled with air but not sealed yet from travelling forward, so as to form a sealed high-pressure region and maintain the pressure in an inflation region, thus maintaining the pressure in the air cushion film after heat-sealing.
