After the metering pump 1 is started, under the action of the output pressure of the metering pump 1, the melt enters the melt-blowing die head 3 through the melt pipe 2 and the first flow channel 57 and then enters the melt-blowing assembly 4. When the melt-blowing component 4 needs to be replaced, the control ball valve 5 is in a closed state, at the moment, the melt in the melt pipe 2 cannot continuously flow downwards, and at the moment, the melt in the melt pipe 2 flows through the second flow passage 58, the first flow passage 57 and the discharge hole 51 in sequence, so that the melt in the melt pipe 2 is discharged through the discharge hole 51, and then the melt-blowing component 4 is removed. When the melt is discharged through the discharge hole, part of the melt may remain on the side wall of the first flow channel, local carbonization or hardening can be generated in the melt remaining in the first flow channel in the whole assembly replacing process, and when the melt after local carbonization or hardening enters the melt blowing assembly, the local blockage of the spinneret hole of the melt blowing assembly can be caused, so that a new melt blowing assembly is scrapped, and the service life of the melt blowing device is reduced.
