Abstract： |
The efficient multineedle electrostatic spinning sprinkling device includes constant pressure supplying system, spinnerette connected with the constant pressure supplying system, receiver electrode plate and electrostatic generator; said spinnerette is multineedle combined spinnerette, it includes spinnerette main body, cover and seal ring the two, the main body is provided with fluid cavity,the bottom of the main body is equipped with several metal nozzles, three adjacent metal nozzles are set up in regular triangle and the abduction of each circle of metal nozzles is in regular hexagon; insulated supporting parts are installed on the bottom of the main body, metal rings encompassing all metal nozzles are installed on the lower of said supporting parts, said metal rings and metal nozzles are connected with electrostatic generator directly. The invention achieves the goal of multi-needle injection simultaneously by improving the intensity of field of spinnerette, reduces the fluid jet electrostatic repulsion forces greatly caused by the small distance between the needles and makes the receiver can receive fiber in small range, so increases the efficiency in unit area and obtains carpet fiber with more uniform thickness. |
