Abstract

The invention discloses a special FPGA (Field Programmable Gate Array) for equipment of functionalized filaments of nanofiber surface coating, belonging to the field of novel textile machinery. The equipment of the functionalized filaments of the nanofiber surface coating includes various models, in the processing procedure of the equipment, different technologies need to be regulated, and the regulation is divided into a single regulation mode, a continuous regulation mode and the like, so that the feeding amount and the feeding speed need to be selected automatically according to the technological requirement, and a manual method obviously cannot meet the technical requirement. For solving the technical problem, the FPGA is used as the core for controlling the system in the invention, and the FPGA finishes the action of reading the designed feeding amount and the feeding rate to produce different coating products, thereby meeting the requirement on design of the functionalized filaments and finishing the production of the filaments having necessary functions.

Description

technical field [0001] The present invention relates to the development of a control system for functionalized filament equipment with nanofibers as a surface coating with FPGA as the core, and specifically relates to using FPGA to read the control data of functionalized filament equipment with nanofibers as a surface coating and store the information in Memory, and use the nanofiber as the surface coating of the functionalized filament device data to control the stepping motor in real time so as to realize the control of the conveying speed and winding action, and to achieve the effect of the non-uniform surface coating of the nanofiber. Background technique [0002] Electrospinning is a high-efficiency and low-cost nanofiber preparation technology. The electrospinning machine is mainly composed of three parts: a high-voltage electrostatic generator, a sampler and a collector. The essence of solution electrospinning is to use a syringe pump to introduce the polymer solutio...
