Embodiment 1

[0026] Such as Figure 1-3 As shown, an electrostatic device of the present invention includes a supply port 5, an electrostatic field generator, and an adder 1, and the electrostatic field generator includes a high-voltage power supply 23, a negative electrode 21, a positive electrode 22, and a device for protecting the electrostatic field environment Electric field cover 7, described negative electrode 21, positive electrode 22 are under the action of high-voltage power source 23, form power line 4 in electric field cover 7; Electric field cover 7 is provided with supply port 5 and suction duct 8, and described supply port 5 and suction The air duct 8 acts to guide the fiber 6 into the electric field cover 7, the electric force line 4 guides the fiber 6 to attach to the free-end whisker 3, and the free-end whisker 3 guides the fiber 6 to enter the twister 1 to be twisted into a yarn; Described adder 1 comprises bell mouth 11, and described bell mouth 11 is used for obtaining...

Embodiment 2

[0028] This embodiment makes the following further limitations on the basis of embodiment 1: as Figure 2-4As shown, a blocking net 14 is provided between the air passage 15 and the transition pipe 12 . The barrier net 14 is used to prevent the fiber 6 from being directly introduced into the condensation tank 16 from the air hole, so as to avoid the direct export of the untwisted fiber 6 . The blocking net 14 is provided with a cross-shaped frame inside, which is spliced ​​with the end face of the air channel 15 through an adhesive, and the center of the cross-shaped frame is on the central axis of the air channel 15 . The cross-shaped retainer plays the role of a small twister, and when a small amount of fiber 6 is directly introduced into the condensation tank 16 from the air channel 15, due to the rotation of the twister, the cross-shaped retainer can also be used for this part of the fiber 6. Twist, and will be on the central axis of the main twisted fiber 6, thereby redu...

Abstract

The invention discloses an electrostatic device, and relates to electrostatic spinning application. The electrostatic device comprises a supply port, an electrostatic field generator and a twister; the electrostatic field generator comprises a high-voltage power source, a negative electrode and a positive electrode; the twister comprises a bell mouth which is used for obtaining fibers introduced from fringings at free ends and made of antistatic plastic; after passing through the bell mouth, the fibers sequentially pass through a transition tube, a conveying tube, a gathering groove and a spinning cup and then form yarn to be guided out; four sections are rotatably and symmetrically arranged in the center of the conveying tube, an air passage is formed on the symmetry axis of the conveyingtube, one end of the air passage is connected with the transition tube, and the other end of the air passage is connected with the gathering groove and is coaxial with the central axis of the spinning cup. By means of the electrostatic device, the situation that the fibers are pulled broken is effectively avoided, the connection of the fibers can be accelerated, the stress process can be simplified, and the efficiency of electrostatic spinning production is improved; the probability of insufficient spinning twisting degree of a finished product is reduced; the electrostatic device has the advantages of being adaptable to the electrostatic spinning process and convenient to use.

Description

technical field [0001] The invention relates to electrostatic applications, in particular to an electrostatic spinning device. Background technique [0002] Electrospinning refers to the use of the force of the electrostatic field on the fibers during the spinning process to straighten, arrange and condense the fibers, and play a role in balancing when the free ends are twisted, so that the spinning can be carried out continuously. . It is a new spinning technology belonging to the category of open-end spinning. The electrospinning device is composed of four parts: a single fiber supply mechanism, an electrostatic field generator, a twister and a winding mechanism. figure 1 It is a schematic diagram of the structure of the electrostatic field generator and the adder. The main technological process is wetting for drawing, carding by low-speed licker-in rollers, air stripping and conveying, orientation arrangement in the electric field of a closed container and high-speed r...
