The web guide system is mainly applied to the lateral deviation control of the coil materials, which can control various reel materials on a production line. The automatic web guide system is simple to operate, easy to install and has fast response speed, strong anti-interference, high-precision web guiding.
The coils are on a long and fast production line, as the speed, tensile, the nonuniform material thickness and all kinds of mechanical damage, resulting in moving and unidirectional deviation, causing the machining operation of the middle section not easy to cooperate, resulting in the loss of many materials and the difficulty of subsequent processing. The automatic web guiding system can solve these problems, which can always keep the edge postilion of the web always be neat and consistent. Web guide control can make steel, corrugated paper, textile, printing, labeling, non-woven fabric processing and other much more industries realize automated control.
A typical automatic web guide system which is a closed-loop system, includes a web guiding controller, a web guide sensor, a web guide framework, and a driver. The sensor detects the difference between the detection value of the edge or the line and the set value, and converts it into a proportional signal through the PLC controller. The driver realizes the web guide. It has three guiding methods, including edge position control, line control and center control.

High-precision Automatic Web Guide System
The precision of the web guide system is defined as the position accuracy of the web just coming out of the probe. The accuracy of the web guiding system is determined by three factors, including the deviation of the invasive web, the accuracy of the web guiding system itself, the installation accuracy of the web guide machine.
The automatic web guide system is a controller of tracking edge or printed line of the working material to perform high-precision differential and swing, which is composed of large-scale industrial integrated circuits, with strong anti-interference ability, high reliability and long service life. The lateral web offset in the transmission is detected by the photoelectric sensor, and the electrical signal proportional to the offset will be sent to the controller. After power amplification, it is sent to the motor to make it rotate forward, stop or reverse and the motor shaft end is connected with a lead screw. The screw drives the roller to move the rolling roller in the rolling rail to move laterally in the offset direction, thereby reaching the purpose of the automatic web guide. The signal is being firmly measured and the high-precision of the web offset is the premise of automatic web guiding.
