Detailed Description

The invention will be further described with reference to specific embodiments, and the advantages and features of the invention will become apparent as the description proceeds. These examples are illustrative only and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications may be made without departing from the spirit and scope of the invention.

Referring to fig. 1, the present invention relates to a melt-blowing apparatus, which includes a processing chamber 5, a heater 1, a melt furnace 3, and a spraying unit, wherein a feeding port 4 is disposed at the top of the processing chamber 5, one end of an air inlet pipe is communicated with an air outlet of a heating blower, the other end of the air inlet pipe extends into the processing chamber, the melt furnace is disposed outside the processing chamber, a pressurizer is installed on a pipe between the feeding port of the melt furnace and a discharging port of the processing chamber, and the discharging port of the melt furnace 3 is communicated with the spraying unit through a discharging pipe; the processing chamber 5, the heater 1 and the melting furnace 3 are all connected to the control panel 2.
