Problems solved by technology

Existing electrospinning generally uses relatively small equipment, which has low working efficiency and cannot achieve large-scale continuous production. For some technologies that require the formation of electrospun fiber membranes on the surface of the substrate, the requirements for the mechanism of substrate transmission are more stringent. High, to achieve the continuity and stability of substrate transmission, in order to ensure product quality and production efficiency
In the electrospinning process, it is necessary to use a moving device to drive the nozzle to move back and forth to achieve spinning on the surface of the substrate. The existing moving device usually drives a nozzle to move, and the diameter of the nozzle used is relatively large. Relatively large, but the spinning efficiency is not high, but it is easy to cause uneven spinning

Abstract

The invention discloses a matrix type multi-needle electrospinning equipment, comprising an electrospinning chamber, a feeding mechanism and a receiving mechanism arranged outside one side of the electrospinning chamber, and a transmission mechanism and a spinning mechanism arranged in the electrospinning chamber ; The transmission mechanism includes a driving roller, a driven roller and a steel belt set between the driving roller and the driven roller. , bypass the driven roller, and then come out from the upper part of the feeding channel and wind up on the receiving roller; there is a spinning mechanism under the steel belt on the side close to the driving roller, which is used to spray the electrospinning raw material on the substrate The surface of the non-woven fabric forms a nanofiber film layer. The invention integrates feeding, spinning, drying and receiving into one, forming an integrated large-scale electrospinning equipment capable of continuous production. Its transmission mechanism is more stable, the spinning is more uniform, and the degree of automation and production efficiency higher.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to a matrix multi-needle electrospinning device. Background technique [0002] Electrospinning is a special fiber manufacturing process, which is a technology that jet-spins polymer solutions or melts in a strong electric field. Under the action of an electric field, the droplet at the nozzle will change from a spherical shape to a conical shape, and extend from the tip of the cone to form a fiber filament. This method can produce polymer filaments with nanometer diameters. Existing electrospinning generally uses relatively small equipment, which has low working efficiency and cannot achieve large-scale continuous production. For some technologies that need to form electrospun fiber membranes on the surface of the substrate, the mechanism for substrate transmission requires more High, to achieve the continuity and stability of substrate transmission, in order to ensure prod...
