Abstract

The invention provides a special FPGA (field programmable gate array) controller for functional woven fabric equipment with nanofiber surface coatings, belonging to the field of novel textile machinery. The functional woven fabric equipment with nanofiber surface coatings has various types, different processes need to be adjusted in the processing course and the adjustment modes are divided into single adjustment and continuous adjustment, so the feed quantity and feeding speed need to be automatically selected according to the process requirements, and obviously, the manual method can not meet the process requirements. In order to solve the technical problem, in the invention, an FPGA is taken as the core of a control system and is used for reading the designed actions of the feed quantity and feeding speed, thus manufacturing different coated products to meet the requirements of functional woven fabric design and further completing production of the woven fabrics with essential functions.

Description

technical field [0001] The present invention relates to the development of a control system for functionalized woven fabric equipment using nanofibers as surface coatings with FPGA as the core, in particular to using FPGA to read control data of functionalized woven fabrics equipment using nanofibers as surface coatings and storing the information to Memory, and use the nanofiber as the surface coating of the functionalized woven fabric equipment 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 solu...
