Embodiment Construction

[0009] The present invention will be described in further detail below

[0010] The invention mainly includes a transmitting device, a receiving device and an electrostatic generator.

[0011] The launching device includes a sealing cover connecting bolt (5), an upper sealing cover (6), a rotating shaft (7) with a protrusion (11), a heating rod (8), a lower sealing cover (12), and a feeding device (13). Among them, the heating rod (8) is located in the rotating shaft (7) with protrusions, and the heating rod (8) is required not to rotate, and the right end of the heating rod (8) is matched with the stepped hole in the rotating shaft (7) with protrusions to heat The left end of the rod (8) is threadedly connected with the heating rod holder, so that the heating rod does not rotate with the raised rotating shaft (7). The sealing cover consists of two parts, the upper sealing cover (6) and the lower sealing cover (12). There is a rectangular hole on the top of the upper sealing ...

Abstract

The invention discloses an upward spinning type melt electrostatic spinning device using a rotary shaft with an embossment as an emitter, and belongs to the field of electrostatic spinning. The melt electrostatic spinning device comprises an emission device, a receiving device and an electrostatic generator, wherein the emission device mainly comprises the rotary shaft with the embossment, a sealing cover and a heating rod; a rectangular hole is formed in the top of the sealing cover; the heating rod is arranged in the rotary shaft with the embossment; the receiving device is positioned above the emission device and mainly comprises a nonmetal net belt; and the net belt is driven by a motor-driven shaft to rotate so as to continuously receive spinning fibers. According to the melt electrostatic spinning device, superfine fibers with the diameters of less than 500 nm can be subjected to large-scale preparation.

Description

technical field [0001] The invention relates to a melt electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique [0002] Electrospinning is divided into two methods: solution electrospinning and melt electrospinning. Compared with solution electrospinning, melt electrospinning has attracted widespread attention due to its advantages of no pollution, high efficiency, and low cost. For complexity, the speed of development is significantly affected. At present, there are two urgent problems to be solved in melt electrospinning: first, how to obtain a large number of fibers with a diameter of less than 500 nanometers; second, how to realize industrial production. [0003] The basic principle of electrospinning is to use electrostatic force as traction force to prepare ultrafine fibers. So far, melt electrospinning has not been able to prepare a large number of fibers with a diameter of less than 500 nanometers. In the present i...
