The journey of this industry marks the progress and breakthrough of China's industrial packaging, achieving the concept of energy conservation and environmental protection. According to incomplete statistics, the use of web guiding systems can save about 10% to 20% of materials. Energy conservation and emission reduction play an important role in industrial web guide. web guide control enables automated control in industries such as steel, corrugated paper, textiles, printing, labels, labeling, papermaking, plastic films, building materials, cables, rubber, tires, and non-woven corrugated paper processing. The photoelectric web guide system is a new type of web guide control system for light industrial automation. It is suitable for various occasions where transverse deviation control of strips is required. It can be matched with slitting machines, bag making machines, laminating machines, coating machines, paper machines, printing presses and textile and building materials machinery that require deviation control. . The photoelectric web guide system uses a single or two-channel digital photoelectric sensor, uses a permanent magnet synchronous AC motor to drive the ball screw as the actuator, and is fully digital circuit controlled.
