Abstract

The invention provides a special DSP (digital signal processor) controller for preparing functional filaments with nanofiber surface coatings, belonging to the field of novel textile machinery. The functional filaments with nanofiber surface coatings to be prepared have 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, a DSP 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 filament design and further completing production of the filaments with essential functions.

Description

technical field [0001] The present invention relates to a control system for functionalized filament equipment using DSP as the core to develop nanofibers as surface coatings, in particular to using DSP to read the control data of functionalized filaments equipment using nanofibers as surface coatings and storing the information to 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 solution in the syringe into t...
