Technical Field
The utility model belongs to the technical field of industrial control, concretely relates to weight device and rolling machine for coiled material tension calibration.
Background
In the processing and production processes of various strips, the unwinding tension is unstable due to the large-range change of the unwinding diameter and the material roll inertia of the strips, and the product quality and the production speed of subsequent processes are seriously influenced. In the process of winding, unwinding and transmission of general coiled material equipment, in order to ensure that the tension of front and rear coiled materials is consistent, a tension control system is arranged. The existing tension control system generally comprises a tension sensor, a tension controller and a tension brake device, wherein the tension sensor, the tension controller and the tension brake device form a tension closed-loop control system, so that the tension is ensured to be in a set value range, and the tension of the system is kept consistent. After the tension sensor is used for the first time or used for a long time, the tension sensor needs to be subjected to tension calibration, so that the tension sensor is prevented from generating deviation to cause the deviation of a tension control system, and therefore the obtained data has a large error.
Chinese patent document CN 103135467B discloses a nonlinear real-time compensation control method for unwinding tension of a strip. The method comprises the steps of firstly calculating the current unreeling radius and unreeling speed in the unreeling process of the strip according to the unreeling shaft rotating speed sensor signal, the unreeling diameter sensor signal, the strip tension expected value, the strip thickness, the strip width, the strip density, the reeling shaft radius, the reeling shaft inertia and other inherent parameters, calculating the unreeling inertia, calculating the currently required unreeling torque on the basis, and finally converting the unreeling torque into a voltage control signal to be output to a torque instruction receiving end of an unreeling motor driver to realize the control of unreeling tension, so that the dynamic and static performances of the unreeling tension of the strip meet the production requirements. However, the method is complex in calculation, low in universality and not practical in actual production.
