The invention provides a six-face beautifying structure of a film packaging machine. The six-face beautifying structure comprises a up-and-down flattening mechanism, a left-and-right lateral face flattening mechanism, a front-and-back end face flattening mechanism, a conveying mechanism, a power mechanism and a support, wherein the bottom face of the up-and-down flattening mechanism is fixed to a film packaging main machine; the up-and-down flattening mechanism is connected with the conveying mechanism through the power mechanism; the left-and-right lateral face flattening mechanism is symmetrically arranged on the two sides, parallel to the conveying direction, of the conveying mechanism; the front-and-back end face flattening mechanism is symmetrically arranged on the two sides, perpendicular to the conveying direction, of the conveying mechanism; the conveying mechanism is connected with the film packaging main machine through the support; one end of a cog belt is connected with the power mechanism; the other end of the cog belt is connected with a motor of the film packaging main machine. Flattening of six faces of packaged films can be completed at a time, the six-face beautifying structure can be additionally arranged on the original film packaging machine for cooperative use, and at the same time, as the motor of the film packaging machine is shared, the synchronism is ensured, the film packaging quality is improved, efficiency is high, and the performance is stable.
