Abstract

The invention discloses tip-end type needle-free electrostatic spinning equipment which comprises a spinning solution storage box, base cloth, a spinning device and a negative-high-voltage direct-current power source, wherein the spinning device comprises a spinning box body, a needle plate, a chain, a negative electrode and a connecting device. The spinning box body is fixedly connected at the top end of the spinning solution storage box, and the chain is connected on the inner wall of the spinning box body. The connecting device is connected with a transmission device to achieve rotation of the chain, a lowermost link of the chain is submerged in spinning solution of the spinning solution storage box, and the needle plate is fixedly connected on the chain. The base cloth covers the top end of the spinning box body. The spinning solution storage box, the spinning box body and the base cloth form an enclosed spinning space. The negative electrode is attached to the top surface of the base cloth. The spinning device is earthed, the negative electrode is connected with the negative-high-voltage direct-current power source, and a high-voltage electrostatic field is formed between the negative electrode and metal card clothing. The tip-end type needle-free electrostatic spinning equipment can improve the yield and the uniformity of nanofiber products, the fineness of nanofiber manufactured through the tip-end type needle-free electrostatic spinning equipment is small, and the variation of the fineness is less.

Description

Technical field [0001] The present invention involves static spinning technology. Specifically, it involves a cutting -edge needle -free static spinning equipment. Background technique [0002] Electricity spinning technology is a technology that uses the static field to prepare nano -fiber materials. In recent years, it has become a research hotspot at home and abroad. Its process principle is: under the action of a high -voltage electrostatic field, the hanging small liquid dripping at the capillary mouth is dripping at the electrostatic powerThe top of the top is emitted at the top of the action. During the movement of the receiving device, the solvent volatilized and solidified into fibers.Static spinning technology is divided into two categories: needle and needleless.Multi -needle or multi -nozzle static spinning technology is considered to be an effective method for achieving large -scale nano fiber material production. One of the representatives of this technology is the ...
