Description
Technical field
The invention belongs to machine control techniques field more particularly to a kind of rationality tension control system and its control methods.
Background technique
In process of production, raw material and semi-finished product need repeatedly to be transmitted by discharging roll, receiving volume and transmission deflector roll
Transfer, needs to carry out tension force in the production line.Tension force is referred to the continuous movement of work between two tools
Or the technology that tension suffered by static machined material carries out automatically controlling.This technical requirements raw material is conveyed in equipment
During, extension degree can control in a certain range, i.e., equipment must all be kept effectively under any speed of service,
Acceleration including equipment is slowed down and at the uniform velocity state;Even if emergent stopping occurs in the process of running, should also have the ability to guarantee quilt
Transferring raw material is not damaged.Therefore, the stability of tension force and the quality of product have direct relationship.It is former if tension is insufficient
Phenomena such as material is easy to produce drift during conveying, and the finished paper after will appear cutting and rewinding wrinkles;If overtension, then
Raw material is easy to be pulled off impaired, reduces the qualification rate of finished product, increases the loss and production investment of raw material.
Summary of the invention
The purpose of the present invention is to provide a kind of rationality tension control system and its control methods, to realize the tune to tension
It is whole, the stability and accuracy of tension force are improved, guarantees product quality.
In order to achieve the above object, base case of the invention are as follows: a kind of rationality tension control system, including Human-machine Control

Target material rationality tension force F value out.Its calculation method:
Target material rationality tension force T value=(target material width K value/fixed width kn value) * unit tension " X
Value ";
Step C, zooming unit passes through target material rationality tension force F value as a result, reason needed for calculating cylinder input terminal
By pressure P value, the output threshold values T value of electronically controlled proportional valve is gone out by theoretical pressure P value equivalency transform.Its calculation method:
Theoretical pressure P value=target material rationality tension force T value * (mechanical lever ratio: the H1 of the H2/5-1 of 5-2)/gas
4 input terminal forced area S value of cylinder;
Export threshold values T value=theory pressure P value/[(equivalent corresponding maximum pressure Pa value-threshold values Min value of threshold values Max value etc.
Imitate corresponding minimum pressure Pi value)/(threshold values Max value-threshold values Min value)];
Step D, threshold values T value will be exported by zooming unit and is placed in electronically controlled proportional valve, and control electronically controlled proportional valve target aperture,
To make the input pressure of air pressure input module by pipeline after electronically controlled proportional valve and cylinder connecting line, in cylinder input terminal
Theoretical pressure P value is obtained, so that mechanical lever be pushed to move around rotating middle shaft, the main rotating roller on mechanical lever is made to push target
Material forms rationality tension force F value.
Control method matched with this control system is set in this way, more clearly recognizes this control system convenient for operator,
Understand that operator to the operating procedure of device thorough, it is simple and clear, avoid operator from carrying out maloperation to device and make
Device or rapidoprint damage.
