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
The present invention relates to DSP is that core exploitation nanofiber is established Beck-up Control System as the functionalization long filament of face coat; Be specifically related to utilize DSP to read nanofiber as the control data of the functionalization long filament equipment of face coat and store this information to memory; Thereby and realize control with this nanofiber as the real-time control step motor action of the functionalization long filament device data of face coat to transporting velocity and coiling action, with the effect of nanofiber heterogeneity face coat.
Background technology
Electrostatic spinning is a kind of efficient nanofiber technology of preparing.Electrostatic spinning machine mainly is made up of HV generator, injector and gatherer three parts.The essence of solution electrostatic spinning is to utilize syringe pump that the polymer solution in the injection-tube is introduced shower nozzle; Under the high voltage electric field effect, the most advanced and sophisticated drop of shower nozzle is pulled into the taper (Taylor awl) that semiapex angle is about 49.3 ° by hemispherical, when applied voltage reaches critical value; Electrostatic repulsion forces overcomes the surface tension of solution; Charged jet is just from vertex of a cone ejection, and it is moving to experience whip then, receives electrostatic repulsion forces simultaneously and continues elongation; The final solvent volatilization is solidified into silk and deposits on the ground connection gatherer, forms the nanoscale film.
Through the nano-fiber film of method of electrostatic spinning preparation, separate relatively difficulty from gatherer, and its intensity is very low at present, separation process damages easily, and then has limited the preparation size of film, and applying of film is limited.In order to address the above problem, a kind of processing method of the functionalization long filament based on the electrostatic spinning nano fiber face coat is proposed.Utilize the carrier of long filament, form face coat, realize the preparation of functionalization long filament simultaneously through take up roll winding filaments carrier at filament surface as nanofiber.The nano coating equipment production flow is as shown in Figure 1.
Nano coating device structure sketch map is as shown in Figure 2: solution forms nanofiber through after the injection of injection-tube between the electric field that forms between taylor cone and the receiver.Chemical-fibres filaments through nanofiber coating, is wound up into the functionalization long filament that forms the nanofiber face coat on the coiling roller after the feeding of input roller.
At present, the control of nano coating equipment can only be accomplished by machinery, time-consuming, effort, and the change of the pattern of coating simultaneously is difficulty quite.Along with people's constantly proposes requirement new and small lot processing to nano coating equipment, and the existing mechanical mode can't satisfy demand of practical production.The present invention is directed to this critical process exploitation one and overlap special-purpose DSP control system, realize real-time control, guarantee the efficient consistent of production with the product of being produced to this equipment.
Summary of the invention
Beneficial effect of the present invention is: use the carrier of long filament as nano-fiber film; With prepared nano thin-film with the smooth filament surface that is coated on of the form of similar cladded yarn; Overcome the shortcoming that nano thin-film intensity is low, produce poor efficiency and be difficult to utilize, prepared functionalization long filament with relevant nanometer fiber properties.
The design principle and the implementation method that the purpose of this invention is to provide a kind of nano coating nonshared control unit utilize the control technology of DSP to realize the Automatic Control that nano coating is produced.
Concrete steps are:
(1) selects suitable DSP;
(2) the PCB development board of design control system;
(3) Design of System Software;
(4) software debugging, the requirement of realization system control.
(5) utilize the same speed of two skin rods to rotate in the same way, realize the coating effect of nano-fiber film long filament.
(6) adopt two shower nozzle relays to spray silk, utilize the method for nanofiber face coat to realize functionalization processing long filament to guarantee long filament by the smooth coating of nanofiber.
The present invention utilizes DSP to realize the control to nano coating, for real-time, the efficient and Automatic Control that further realizes coating has proposed new thought.
