Description
Technical field
The utility model relates to a kind of frequency-converter device, is specifically related to a kind of vector tension force frequency-converter device.
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 all is widely used.Before converter technique does not also have maturation, usually 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 appearred.Its controller performance can compare favourably with the DC control performance.Because a lot of aspects such as the structure of alternating-current motor/AC motor, cost performance, use, maintenance all are better than DC motor, vector converter is controlled and just in these industries, is being applied more and more widely, and the trend that replaces DC control is arranged.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, has proposed a kind of vector tension force frequency-converter device, and the closed-loop tension control under velocity mode reaches constant tension by regulating motor speed.At first by the linear velocity of band (line) and the coil diameter of reel, calculate in real time the simultaneously match frequency instruction, then tension signal and the tension force setting value by tension detecting device, fed back form the PID closed loop, adjust the frequency instruction of frequency converter, the purpose that tension force is controlled is exactly the constant tension kept on wire rod or band, and vector-control frequency converter can achieve the goal by two kinds of approach: one, by the rotating speed of controlling motor, realize; Another kind is to realize by controlling motor output torque, the method of vector converter technology in batching application is varied, under the 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.
The technical solution of the utility model is: a kind of vector tension force frequency-converter device 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 on 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 an end of frame;
Described frame is provided with opto-electronic pickup.
The utlity model has following beneficial effect:
The utility model is simple and reliable for structure, easy to maintenance, practical, and efficiency is high.
The accompanying drawing explanation
Accompanying drawing is the utility model vector tension force frequency-converter device structural scheme of mechanism.
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:
