The major obstacle that hinders electrostatic spinning technique industrialization paces has two: the one, and electrostatic spinning efficient is too low.Though the existing many reports of patent about the electrostatic spinning apparatus produced in batches, but these devices all are at the solution electrostatic spinning, and solution electrostatic spinning process has 90% solution all to evaporate with the form of solvent, and this is the not high immediate cause of solution electrostatic spinning efficient.The 2nd, the research about electrostatic spinning at present concentrates on solution electrostatic spinning aspect mostly, and the solution electrostatic spinning a series of problem occurs because will use solvent: as the recovery problem of solvent; Be applied to the safety problem of biomedicine field; Some polymer such as polypropylene and polyethylene at room temperature can not find the appropriate solvent wiring solution-forming; The evaporation of solvent causes fiber surface rough, even defective occurs; The use of expensive solvent can increase cost; Fine spinneret orifice stops up easily, and influence is produced or the like continuously.The use of solvent is that electrostatic spinning technique is difficult to industrialized basic reason.
The utility model content
But a kind of quantity-produced high-efficiency melt electrostatic spinning device that the utility model proposes does not need to use solvent to carry out spinning, thereby has avoided using solvent and the problem that occurs; The melt of melt spinning process 100% all is converted into product, realized zero loss, improved the efficient of electrostatic spinning greatly, each efficient shower nozzle of spinning process can both produce the melt jet stream of multiply, thereby has further increased substantially the efficient of melt electrostatic spinning.The utility model has solved industrialized two major obstacles of obstruction electrostatic spinning technique, has promoted the industrialized paces of electrostatic spinning technique greatly.
But the utility model provides a kind of quantity-produced high-efficiency melt electrostatic spinning device, and it comprises precision extrusion molding machine that extrusion capacity can accurate control, is evenly equipped with the spray silk die head of a plurality of spinneret orifices, can makes injection stream be divided into the Height Adjustable receiving system of the efficient shower nozzle of multiply, the HV generator with anodal output and reel etc.The precision extrusion molding machine adopts bolt to be connected with spray silk die head, efficient shower nozzle adopts conical surface tight fit to be connected with spray silk die head, receiving system is made up of reel and tape handler etc., the reel of receiving system has lowering or hoisting gear, be used for the adjusting of its height, reel can be for convenience detach, is easy to change reel after silk twines completely.
Precision extrusion molding machine in the utility model can be single screw extrusion machine or double screw extruder or multi-screw extruder.
The reel lowering or hoisting gear of receiving system can be screw mechanism or pneumatic mechanism or hydraulic mechanism.
For fear of the interference of high-pressure electrostatic to the precision extrusion molding machine, this device adopts inverted electric field promptly, efficiently shower nozzle ground connection, so all unnecessary electric charges by the electrostatic field generation all can flow to the earth rapidly, has protected precision extrusion molding machine and all sensing elements that spray the silk die head such as sensor etc.; The reel of receiving system is a conductive material, it is connected with the positive pole of HV generator by metal bearing, the support and the used belt of tape handler that support reel all are insulating materials, the motor of tape handler and the reel segment distance of being separated by, thus the influence of high-voltage electrostatic field avoided to motor.
The used precision extrusion molding machine of the utility model, it is extruded flow and can accurate control, and minimum speed can be controlled at 0.5r/min, thereby has guaranteed the stability of flow of spray silk die head.Be evenly equipped with a lot of spinneret orifices on the base plate of spray silk die head, the minute aperture of these spinneret orifices and general spray silk die head is different, and its diameter can be greater than 2mm, thereby has reduced difficulty of processing greatly.Spinneret orifice adopts conical surface tight fit to be connected with efficient shower nozzle, owing to cut several planes equably on the mating surface of efficient shower nozzle and spinneret orifice, melt can flow to the spray screw tap face of efficient shower nozzle equably by these fit clearances, just can form the melt jet stream of multiply under the effect of electrostatic field.Efficient shower nozzle can be one or more, and the spray silk unit of being made up of a plurality of efficient shower nozzles can improve the efficient of electrostatic spinning significantly.
But a kind of quantity-produced high-efficiency melt electrostatic spinning device that the utility model proposes, electrostatic spinning technique be used for quantity-produced Polymer Processing equipment precision extrusion molding machine and combine, realized the continuous production of melt electrostatic spinning technology, efficient is improved, for solid foundation has been established in the electrostatic spinning technique industrialization.
