Rectification control system

Abstract

The application provides a rectification control system. The rectification control system comprises a first collector, a rectification device and a controller, wherein the first collector is used for collecting the current distance value between a belt material standard line and a preset fixing point when the belt materials are conveyed on a guide roller; the rectification device is used for changing the conveying track of the guide roller; the controller is used for comparing the current distance value and the preset standard distance value and judging whether the difference between the current distance value and the standard distance value meets a first preset condition; and the first preset condition is as follows: the difference between the current distance value and the standard distance value is in a preset difference range; when the difference does not meet the first preset condition, the belt materials are judged to be in defection, control signals are generated according to the difference, the rectification device is controlled to change the conveying track of the guide roller so as to rectify the belt materials. As the rectification control system of the application is adopted, the deflected belt materials can be moved to a standard position in real time, the deflection of the belt materials is rectified with high precision, and the processing quality of the belt materials is improved.

Description

technical field [0001] The application relates to the field of strip production, in particular to a deviation correction control system. Background technique [0002] In the strip continuous production equipment and strip processing equipment, the strip walks on the guide roller, as long as the strip and the surface of the roller are in contact and within a certain friction resistance limit, then at each point on the strip, it will be Running at right angles to the centerline of the rollers, the tension of the strip is evenly distributed. That is, when the strip is on the roller, the strip will run perpendicular to the centerline of the roller. [0003] However, in the actual production process, there will be various external disturbances, such as uneven winding in the previous process or deviation and vibration (swing) of the guide roller in this unit, as well as strip tension and speed imbalance of each part, etc. It will cause the edge of the strip to be unable to be pa...

Problems solved by technology

[0003] However, in the actual production process, there will be various external disturbances, such as uneven winding in the previous process or deviation and vibration (swing) of the guide roller in this unit, as well as strip tension and speed imbalance of each part, etc. It will cause the edge of the strip not to be parallel to the center line of the train, or the center line of the strip cannot coincide or be offset with the center line of the train, which is commonly known as strip deviation

[0004] Once the strip deviates, it will affect the subsequent processing steps. For example, the cutting step cannot be cut to the desired cutting position correctly, resulting in the failure of the product to meet the requirements and reducing the processing quality of the strip.
