Description
Technical field
The present invention relates to a kind of frequency-converter device, be specifically related to a kind of new type inverter.
Background technology
In industrial a lot of industries, all to carry out accurate tension force control, keep the constant of tension force, to improve the quality of product.Industries such as papermaking, printing printing and dyeing, packing, electric wire, fibre-optic cable, weaving, leather, metallic paper processing, fiber, rubber, metallurgy is all widely used.Before converter technique does not also have maturation, conventionally adopt DC control, to obtain good controller performance.Along with reaching its maturity of converter technique, some performance-oriented frequency converters such as vector-control frequency converter, tension force control special converter have been there are.Its controller performance can compare favourably with DC control performance.Because a lot of aspects such as the structure of alternating-current motor/AC motor, cost performance, use, maintenance are all better than DC motor, vector converter is controlled and just in these industries, is being applied more and more widely, has the trend that replaces DC control.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, has proposed a kind of new type inverter, and the closed-loop tension control under velocity mode is by regulating motor speed to reach constant tension.First by the band linear velocity of (line) and the coil diameter of reel, calculate in real time simultaneously match frequency instruction, then the tension signal feeding back by tension detecting device and tension force setting value form PID closed loop, adjust the frequency instruction of frequency converter, the object that tension force is controlled is exactly the constant tension keeping on wire rod or band, and vector-control frequency converter can achieve the goal by two kinds of approach: one, by controlling the rotating speed of motor, realize; Another kind is to realize by controlling motor output torque, the method of vector converter technology in batching application is varied, under current techniques condition, above-mentioned pattern is the most representative, converter technique is also at high speed development, new theory and control technology will continue to bring out, and master mode is also weeded out the old and bring forth the new continuing.
technical scheme of the present invention is: a kind of new type inverter, comprises tensioner, nip rolls, wrap-up, floating roller, driving device, frame, motor and control desk; Tensioner is connected with nip rolls by curling band, described nip rolls are connected with floating roller by track adjusting wheel, described floating roller is connected with wrap-up by flower wheel, driving device is fixed in frame, described wrap-up is arranged on driving device, one side of described driving device is equipped with motor, and control desk is contained in one end of frame;
Described frame is provided with opto-electronic pickup.
The present invention has following beneficial effect:
The present invention is simple and reliable for structure, easy to maintenance, practical, and efficiency is high.
Accompanying drawing explanation
Accompanying drawing is new type inverter structural scheme of mechanism of the present invention.
In figure: 1, tensioner; 2, nip rolls; 3, track adjusting wheel; 4, wrap-up; 5, floating roller; 6, flower wheel; 7, driving device; 8, frame; 9, opto-electronic pickup; 10, motor; 11, control desk.
the specific embodiment:
Shown in accompanying drawing, the present invention includes tensioner 1, nip rolls 2, wrap-up 4, floating roller 5, driving device 7, frame 8, motor 10 and control desk 11; Tensioner 1 is connected with nip rolls 2 by curling band, described nip rolls 2 are connected with floating roller 5 by track adjusting wheel 3, described floating roller 5 is connected with wrap-up 4 by flower wheel 6, driving device 7 is fixed in frame 8, described wrap-up 4 is arranged on driving device 7, one side of described driving device 7 is equipped with motor 10, and control desk 11 is contained in one end of frame 8; Described frame 8 is provided with opto-electronic pickup 9; Under the control of control desk 11, the present invention is under the signal of opto-electronic pickup 9 guides, and motor 10 starts and works, and drives wrap-up 4 and tensioner 1 to carry out work.
