Matrix type multi-needle electrostatic spinning equipment

Abstract

The invention discloses matrix type multi-needle electrostatic spinning equipment which comprises an electrospinning chamber, a feeding mechanism and a collecting mechanism arranged outside one side of the electrospinning chamber, and a conveying mechanism and a spinning mechanism arranged in the electrospinning chamber, wherein the conveying mechanism comprises a driving roller, a driven roller and a steel belt arranged between the driving roller and the driven roller in a sleeving mode; a movable end of a non-woven fabric base material on a feeding roller penetrates through a material passing channel, then bypasses the driven roller along the lower surface of the steel belt, comes out of the upper part of the material passing channel and is wound on the collecting roller; and a spinningmechanism is arranged below the steel belt close to one side of the driving roller and is used for spraying an electrostatic spinning raw material on the surface of the non-woven fabric base materialto form a nanofiber membrane layer. The electrostatic spinning device integrates the functions of feeding, spinning, drying and collecting; the integrated large electrostatic spinning equipment capable of achieving continuous production is formed; the conveying mechanism of the equipment is more stable, spinning is more uniform, and the automation degree and the production efficiency are 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...

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
