A melting blow nonwoven cloth processing machine belongs to the nonwoven machinery technology field. The machine comprises a first machine frame, a melted extrusion mechanism which is arranged in a horizontal state at the rear of the first machine frame and used for processing plastic particles into hot melted fibers, a short fiber transportation mechanism which is arranged at the front of the first machine frame and used for delivering the short fibers to a destination in front of the spinneret of the melted extrusion mechanism and compelling the short fibers and the hot melted fibers sprayedout by the spinneret to converge to form a melting blow fiber layer, and a composite forming mechanism used to complex nonwoven fiber cloth with the top surface and the bottom surface of the meltingblow fiber layer to form a finished melting blow nonwoven cloth finish product, and the composite forming mechanism is arranged under the short fiber transportation mechanism and corresponds to the front of the spinneret. The processing machine has the advantages that the arrangement of the melted extrusion mechanism, the short fiber transportation mechanism and the composite forming mechanism isreasonable, the structure is simple; and the cooperative operation of the three mechanisms can satisfy the processing technology requirement of continuously producing the melting blow nonwoven cloth and the requirement of batch production capacity.
