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

Description

technical field [0001] The invention relates to the technical field of electrostatic spinning equipment, in particular to a large modular combined electrostatic spinning equipment. 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 transmi...
