Abstract
Provide a kind of system that can realize drafting multiple digitlization and regulate on drawing frame, solve the accurate control to output sliver weight in drawing frame.Comprise servo drive system, servomotor, PLC, man-machine interface, transmission system, frequency converter, main drive system.Wherein PC1 is mounted in the photoelectric encoder on a roller, and PC4 is mounted in the photoelectric encoder on four rollers, and a roller of driven by servomotor two, three, four roller and main drive systems forms speed discrepancy, namely forms required drafting multiple.This drafting multiple is linear, can step-less adjustment.When spinning process adjusts, the drafting multiple (drawing-off scope 4.00 ~ 15) needed for being inputted by man-machine interface, or input required output strip gravimetric value (10.00-30.00g/5m), Lookup protocol drafting multiple.
Description
Technical field
The utility model relates to a kind of field of textile machinery, specifically a kind of system that can realize drafting multiple linear regulation on drawing frame.
Background technology
In drawing spinning yarn process, the adjustment (being exactly specifically the rotating speed of adjustment roller) of drafting multiple is very large to the influence of yarn index, and the adjustment of traditional draft of drawing frame multiple mainly relies on the number of teeth of conversion transmission system middle gear or the diameter of belt wheel to realize.The adjustment of its drafting multiple is wasted time and energy, and its drafting multiple manifests nonlinear stairstepping with sliver weight distribution curve, can not realize the accurate adjustment of counter extensioin multiple.
Summary of the invention
The utility model is in order to solve the accurate control to output sliver weight in drawing frame, and realize drafting multiple digitlization fine adjustment, provide a kind of can realize on drawing frame drafting multiple digitlization regulate system and output sliver weight manifest linear relationship with drafting multiple.
The technical solution adopted in the utility model: the system that drafting multiple digitlization regulates can be realized on drawing frame, it is characterized in that comprising the man-machine interface, PLC, servo-driver, the servomotor that connect successively; Servomotor connects and drives roller system, and first roller axle head in roller system installs a photoelectric encoder, on least significant end roller axle head, also install photoelectric encoder, described two photoelectric encoders are by main drive system and frequency converter access PLC and by the speed feedback of first and last two rollers in PLC simultaneously.
The utility model when spinning process adjusts, the drafting multiple (drawing-off scope 4.00 ~ 15) needed for being inputted by man-machine interface, or input is required exports strip gravimetric value (10.00-30.00g/5m), Lookup protocol drafting multiple.One roller of driven by servomotor two, three, four roller and main drive systems forms speed discrepancy, namely forms required drafting multiple.This drafting multiple is linear, can step-less adjustment.
Accompanying drawing explanation
Fig. 1 is the utility model system construction drawing;
Fig. 2 is the utility model electrical schematic diagram.
Detailed description of the invention
Contrast accompanying drawing 1,2 to be below described this structure:
Man-machine interface input control order the working condition of display system; PLC provides frequency converter instruction and receives frequency converter feedback signal; PLC provide servo-driver control instruction and and receive servo-driver feedback signal; The rotating speed of a roller is controlled according to the main drive system of the instruction of PLC; Servo-driver controls the rotating speed of servomotor; Servomotor controls the rotating speed of two rollers, three rollers, four rollers by transmission system; Rotating speed between two rollers, three rollers, four rollers distributes through transmission system.PC1 photoelectric encoder is arranged on a roller axle head, and PC4 photoelectric encoder is arranged on four roller axle heads, and by respective speed feedback in PLC.Wherein PC1 is mounted in the photoelectric encoder on a roller, and PC4 is mounted in the photoelectric encoder on four rollers, realizes the servo-actuated of servomotor and mair motor rotating speed by mathematical logic.The rotating speed of servomotor is N2n=N1n/Ku; wherein N1n is the rotating speed of the photoelectric encoder on a roller; N2n is the rotary speed setting value of two roller servomotors; Ku is the drafting multiple arranged on man-machine interface interface; the change of the drafting multiple of a roller and four rollers is detected in real time by photoelectric encoder; when drafting multiple change is more than 1%, control system sends reports to the police and shuts down.
