The working principle of the correction system



Number of views:

Coil correction control system is a closed-loop controller, sensors, linear guide mechanism constitute the basic part of closed-loop control. First, the correction sensor detects the edge or line of the coil, the system automatically reads the offset between the actual position of the coil and the set position, and converts the offset into an electrical signal proportional to it and transmits it to the controller. The signal is amplified and calibrated by the controller and then output to the linear driver. The linear driver drives the correction and alignment mechanism according to the size of the signal to restore the coil to the set position. The driving signal of the current driver is only proportional to the amount of coil deviation, which makes it possible to provide accurate control for various coil and correction systems.
-- Industrial control systems used in steel, corrugated paper, textile, printing, labeling, paper, plastic film, building materials, cables, rubber, tires and other industries. Correction control refers to the technical operation taken to keep the sides of the coil neat and consistent during spraying, printing, punching, laminating, slitting or other coil winding processes produced by the manufacturer, because once the edges of the coil are not aligned, subsequent work steps will be wrong, resulting in material waste or shutdown adjustment. Therefore, when dealing with the processing of coils, it is necessary to correct the deviation of the offset coils in time, which is called correction. The equipment of the whole process constitutes a set of correction system. Rectification system involves a wide range of packaging, printing, labels, building materials, pulp, household paper, plastics, clothing, cables, metal processing, non-woven fabrics, corrugated paper processing and other industries are essential. A typical correction system includes a correction controller, a correction sensor, a correction frame and a driver.
