Description
Technical field
The utility model relates to a kind of for the shower nozzle on miniature melt blowing machine.
Background technology
It is a kind of in extruded polymer method nonwovens process that meltblown is prepared nonwoven material technique, originates from early 1950s.US Naval Research Laboratory research first exploitation, for collecting the filtering material of upper atmosphere radioactive particulate, gives to the world the result of one's studies for 1954.Middle 1960s, U.S. ESSO company (modern Exxon company) further improves this technique, and has obtained relevant United States Patent (USP).The later stage eighties 20th century, exploitation due to melt blown non-woven market, some non-weaving cloth machine-building business start to participate in the manufacture of meltblown production equipment, wherein have Accurate company and the J & M company of the U.S., the Reifenhaeuser company of Germany etc.Since the eighties in 20th century, melt blown non-woven increases rapidly.The Kimble-clark company of the U.S. is in order to overcome the shortcoming that melt blown non-woven is powerful low, melt-blowing nonwoven and filature fleece formation non-weaving cloth laminated material have been developed, be SMS composite, be widely used in operation dress, filtering material etc., effectively promoted the development of melt-blowing nonwoven.
The research of China meltblown nonwovens process started from for 20 century 70 mid-terms; the middle and later periods eighties; melt blown non-woven is widely applied in China, and major product has filtering material, medical and health use material, environmental protection material, dress materials, Wiping material, oil absorption material, heat insulating material formed, battery diaphragm etc.Enter the nineties, along with the maturation of melt blown technology, China has completed the development that wide cut melts and sprays production line.Especially the needs of environment in recent years air cleaning, the demand rapid growth of air filting material, causes melting and spraying the fast development of production equipment.The existing melt blown non-woven production line of China has reached more than 1000 at present.
Melt spraying non-woven fabrics is a kind of high added value, high-tech product, and along with melting and spraying the continuous expansion of weaving material Application Areas, the research of new material is more and more taken seriously, and the exploitation that melts and sprays new product has become the most important thing that each melts and sprays producer.Outside traditional fusion-jetting polypropylene (PP) non-weaving cloth, the polymer chips raw material that melt-blown process is conventional has expanded to PLA (PLA), polyethylene terephthalate (PET), polyamide (PA), polyethylene (PE), polytetrafluoroethylene (PTFE), polystyrene (PS), polybutylene terephthalate (PBT) (PBT), polyurethanes (PU) etc.For meeting the needs that melt and spray new material research and development, the demand of studying the small-sized melt blowing machine of special equipment as nonwoven material also constantly expands.But the exploitation that melts and sprays product needs very large input, and in R&D process, the Meteorological of material accounts for very large ratio, and the input that how to reduce this respect also becomes a problem.But the compressed version that on domestic and international market, existing small-sized melt-blowing equipment is all large-scale melt-blowing equipment at present, its basic structure is suitable with large-scale production line basic configuration, and just ratio is dwindled.Specifically comprise: screw extruder, measuring pump, meltblown beam sub-assembly, air compressor machine, air heater, receiving system, coiler device etc., specifically as shown in Figure 1.When reality is used, have that sample dosage is large, complex process, time cycle are long, high in cost of production problem.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of for the shower nozzle on miniature melt blowing machine.
The utility model is installed on the sample jar bottom of melting test portion sample, and shower nozzle is over against receiving system.Described shower nozzle comprises nozzle and the conical gas outlet centered by nozzle, surrounding in conical gas outlet has guiding gutter, the bottom of guiding gutter has heat of compression air intake, the great Kou UNICOM of the top of guiding gutter and conical gas outlet, heat of compression air enters large mouthful of conical gas outlet after being promoted from the bottom to top by guiding gutter, from after the osculum output ejection of conical gas outlet for draw jet fused raw material out, obtain superfine fibre.
The beneficial effects of the utility model: by the particular design of shower nozzle internal structure, realized even, the stabilization of hot compressed air, stretching fused raw material, obtains superfine fibre.
