Embodiment 1

[0025] The invention relates to a Taylor cone multi-nozzle electrostatic spinning machine, which mainly includes four parts: a nozzle device, an automatic infusion device 2, a high-voltage electrostatic generator 4 and a winding mechanism. Among them, the high-voltage generator adopts the F10-II high-voltage electrostatic generator; the reciprocating motion of the nozzle box 1 is provided by a ZB-0.1 / 8 air compressor to provide compressed air, and the Cylinder SC50-500 provides reciprocating motion power, using two travel switches 7LX19 -001 controls the reciprocation of the motion. The winding mechanism is driven by 100YYJ-250 GEAR MOTOR. The process flow is: turn on the main power switch → turn on the power supply of the high-voltage electrostatic generator to preheat the high-voltage electrostatic generator → start the automatic infusion device for infusion → open the valve of the control box, and the nozzle box starts to reciprocate → turn on the high-voltage switch of the...

Abstract

The invention relates to a Taylor cone multi-nozzle electrostatic spinning machine, which comprises a nozzle box (1), an automatic liquid feeding device (2), a spinneret group, a high-voltage electrostatic generator (4) and a rolling mechanism, wherein the spinneret group is arranged in the nozzle box and is fed with liquid by the automatic liquid feeding device (2), yarns emitted by the electrostatic field generated by the high-voltage electrostatic generator (4) are collected by the rolling mechanism, and the spinneret group consists of a plurality of spinnerets arranged. The invention can improve the quality and the output of felt, and has stable operation and uniform product. Under the same process conditions, the thinness of the spun nanofiber is half the thinness of fiber spun by conventional electrostatic spinning machine.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a multi-nozzle electrostatic spinning machine. Background technique [0002] The polymer solution or melt is charged with thousands to tens of thousands of volts of high-voltage static electricity, and the charged droplets are accelerated at the top of the Taylor cone under the action of the electric field force. When the electric field force is large enough, the polymer droplets can overcome the surface tension and form jet particles. flow. The charged polymer jet is stretched and thinned under the action of electric field force, viscous resistance, surface tension, etc. At the same time, the charged jet bends due to the existence of surface charges in the electric field. The thin stream evaporates or solidifies the solvent during the spraying process, and finally falls on the receiving device, forming a nanofiber mat similar to a non-woven fabric. In recent years, due to the ...
