Abstract
The invention relates to the field of masks, in particular to a melt-blown non-woven fabric forming device, which includes an extruder, a nozzle arranged at the front end of the extruder, and a condensing device, and a short fiber nozzle is arranged between the nozzle and the condensing device. The short fiber spinning device is provided with an arc-shaped blowing port below the short fiber spinning device, and the arc-shaped blowing port points to the condensing screen device, and a horizontal blocking blowing port is arranged above the short fiber spinning device. cavity, tapered guide cavity, spinneret pipe, and spinneret. The spinneret pipe is provided with an arc-shaped expansion chamber, and an annular body is provided on the outer circumference of the nozzle, and a blower is formed between the annular body and the nozzle In the air cavity, one end of the annular body is located at the spinneret, and the other end forms an air guide port with the outside of the nozzle, and a tapered block is arranged between the annular body and the nozzle to form an annular air outlet with a gap. It solves the technical problem in the prior art that bad effects are produced when short fibers are added to hot-melt fibers.
Description
technical field [0001] The invention relates to the field of masks, in particular to a meltblown nonwoven fabric forming device. Background technique [0002] At present, the processing of melt-blown non-woven fabrics usually uses a melt-extrusion mechanism for spinning, and then forms on a condensation mechanism, which is often made of polypropylene material. The processing equipment of existing melt-blown non-woven fabric can refer to a kind of melt-blown non-woven fabric processing machine disclosed in CN200810020638.6, which belongs to the technical field of non-woven machinery, and it includes a first frame; A melting extrusion mechanism that is used to process plastic particles into hot-melt fibers at the rear end of the first frame in a state; one is used to guide short fibers to the front of the spinneret of the melting extrusion mechanism and force Short fibers and the hot-melt fibers ejected from the spinneret merge to form a short fiber conveying mechanism for a ...
