Web guide control refers to the technical operation for the coil materials and must always keep the edge of the coils neat and consistent during the spraying, printing, punching, laminating, slitting or other coil winding processes. Once the edges of the coils are not aligned, it will cause errors in subsequent steps, resulting in material waste. Therefore, when processing coils, it is necessary to do the correct deviations in time for the offset coils. The whole process is called web guiding. The equipment, which is used for the whole process, constitutes a set of web guide system. A typical system includes a controller, a sensor, a guide mechanism and a driver.
The importance of the web guiding system
The flexo printing machine often adopts an automatic web guide system to ensure the stable horizontal position of the printing material before entering the printing unit. It can detect the deviation of a certain horizontal edge position of the printing material and correct it in time, with an accuracy of ±0.5 mm. Generally, for opaque materials, such as paper and aluminum foil, photoelectric sensors are often used, for transparent materials, such as films, ultrasonic sensors are used. Once the printing material enters the printing area and die-cutting rewinding area, the stability of its horizontal edge position is guaranteed by the installation accuracy of the own processing machine and the parallelism between the rollers.
The working principle of the web guiding system
The web guide control system is a closed-loop controller. First, the sensor detects the edge or line of the coil, and the system automatically reads the deviation of the actual position and setting position of the coil and convert the offset into an electrical signal. The send the signal to the controller. After that the signal is calibrated by the controller, it is outputted to the linear driver. The linear driver drives the deviation correction according to the magnitude of the signal. Then the guide mechanism adjust the coil to the set position. The drive signal of the current drive is only proportional to the deviation of the coil, which makes it possible to provide precise control for various coils.
Applications of the web guiding system
The web guide system covers a wide range of applications and is essential in various industries such as packaging, printing, labels, building materials, paper pulp, non-woven fabrics, and corrugated paper processing.

The mask machine is used to produce various masks with certain filtering performance through a series of processes including hot pressing, folding and forming, ultrasonic welding, waste removal, ear belt and nose strip welding of multi-layer non-woven fabric. In the production of masks, multiple layers of materials must be neatly bonded together, otherwise, waster or even jams will occur. The web guiding system can achieve multi-layer material alignment, no waste in the refueling process and the jam never occur. The web guide is a selectable position controller for tracking the edge of the material or printing lines for high-accuracy swing.
How does the web guide machine work
The web guide machine is a position deviation control of the thin material during the conveying process by the motor at a constant speed. If the winding speed of the material needs to be changed, the correction speed cannot be changed, which will easily lead to the phenomenon that the curling cannot be corrected. And the microcomputer photoelectric deviation correction web guiding system can meet customers' needs.
The web guide can be used in flat mask machines. The system includes a computer-controlled photoelectric correction controller, color discrimination tracking photoelectric, ball screw, and synchronous motor. The MCU control used by the computer-controlled photoelectric correction system has a frequency conversion output, which can adjust the motor speed according to the needs. The structure is simple, easy to operate, convenient and practical in production.

Coil materials refer to long-sized continuous materials such as paper, film, sheet, non-woven fabric, metal foil, silk, thread, etc. In the process of uncoiling, technological processing, winding, etc, deviation of the coil materials may occur, due to the deviation of the coil itself or the processing machine. The web guiding control system provides a solution to reduce the occurrence of such situations. The system always tracks the position of the coil material during the production and makes corrections in real-time. It can ensure and improve the quality and efficiency of production.
Working principle of web guiding
The web guiding is to guide the sensor to emit infrared or ultrasonic to monitor the operation of the coil material and send a signal to the controller. After that the controller finds that the web has a positional deviation, according to the preset command by the controller, the controller controls the drive system to swing to correct the web position.
The web guide system uses brushless DC servo motor drive, precision ball screw driv with, compact structure, good mechanical rigidity, low inertia, suitable for high-speed and high-precision web guiding.
The system is composed of a controller, a sensor, an electric driver, and a correction guide mechanism. The sensor detects the edge position of the coil material and reads the deviation between the actual position and the set position, converting the deviation into a voltage signal proportional to it. Then sends this signal to the controller. After the signal is amplified and calibrated by the controller, the signal is output to the electric driver, and the electric driver drives the guide mechanism to perform correction actions according to the magnitude of the input signal to guide the coil material to the preset position.
