Melt-blowing die head with hot runner system

The invention relates to a melt-blowing die head with a hot runner system, and belongs to the field of die equipment. A spinneret orifice is formed in the bottom part of a main die; two air plates aremutually symmetrical with respect to the axis of the spinneret orifice; gap channels are respectively formed between the two air plates and the main die; air inlets of the two gap channels are in butt joint and communication with airflow channels; air outlets of the two gap channels face the discharging direction of the spinneret orifice; the main die is provided with an installation groove for installing the air plates; the length, opposite to the connection direction of the two air plates, of the installation groove is larger than the length of each air plate; the air plates are fixed to the main die through adjusting screws and locking screws; the main die is provided with threaded holes adaptive to the adjusting screws; the screw-thread sections of the adjusting screws are arranged inthe threaded holes; the i
