Looking For Web Guiding Control System

web edge guide system refers to the manufacturer of coil in the process of spraying, printing, punching, laminating, slitting or other coil winding, always to keep the side of the coil neat and consistent and take the technical operation of its wide use has brought great benefits to the industry, correction control makes steel, corrugated, textile, printing, labeling, labeling, papermaking, plastic film, building materials, cables, rubber, tires, non-woven corrugated processing and other industries appear automatic control.

Applications of Web Guiding Control System:
Deviation correction control is mainly used in industrial automation control systems in steel, corrugated paper, textile, printing, labeling, labeling, papermaking, plastic film, building materials, cables, rubber, tires, non-woven fabrics, corrugated processing and other industries. The equipment of the entire process constitutes a set of deviation correction system. Modern coil handling technology is developing in the direction of high speed and high precision, which is increasingly dependent on automatic web guiding technology. A typical automatic guiding system consists of a guiding controller, guiding sensor, guiding frame and actuator.
The web guiding control system is a new type of web guiding control system for light industry automation. It is suitable for various occasions that require strip transverse deviation control. It can be matched with slitting machines, bag making machines, laminating machines, coating machines, paper machines, printing machines, and textile and building materials machinery that require deviation control. The photoelectric web guiding system adopts single or dual channel digital photoelectric sensor, adopts permanent magnet synchronous AC motor to drive the ball screw as the actuator, and adopts full digital circuit control.
Specific application scope: Applicable industries: printing, packaging, papermaking, non-woven fabrics, lithium batteries, solar energy, rubber tires, textiles, metallurgy.
Applicable roll materials: roll paper, film, metal foil, film, leather, non-woven fabric, woven fabric and other winding materials.
Applicable equipment: printing and packaging, flexo printing machine, gravure printing machine, rotary printing machine, label printing machine, slitting machine, coating machine, laminating machine, inspection machine, die-cutting machine, blown film machine, bag making machine, etc.
Non-woven fabrics: sanitary napkin equipment, sanitary napkin production line, baby diaper production line, medical dressing production line, etc.
Lithium battery: pole piece coating machine, pole piece rolling mill, slitting machine, winding machine, etc.
Rubber tires: extruders, cord production lines, calenders, cutting machines, molding machines, etc.

Advantages of the web guiding control system:
Its structure is reasonable, the old and new rollers are higion correction resistance is small, the power consumption is reduced, the action is reliable, the reflection is sensitive, and the automatic and repeated deviation correction for a long time with the help of the belt forward movement power is suitable for working in harsh environments without failure. No lag, the product is durable and easy to repair. It can make the belt always run in the center; Due to the use of the company's own research and development and production of high-precision polyurethane energy-efficient rollers, greatly prolonging the life of the conveyor, the roller not only has high strength, strong sealing, flame retardant and antistatic, corrosion resistance, light weight, low friction resistance, long service life and other characteristics, its bearing capacity is 2 times higher than similar products, under the same conditions its friction and anti-corrosion performance is more than 10 times, dustproof, waterproof performance than similar products increased by 15% and 50%.

The principle of the guiding control system:
Calibration device B emits infrared/ultrasonic/laser/visible light to monitor the operation of the amplitude and sends a signal to controller A. After the controller detects the web position drift, it controls the swing of the correction frame C by driver D, and corrects the web position according to the instruction preset by the controller. The automatic web correction system uses a photoelectric sensor to detect the edge position of the web and sends the measured position error signal to the controller. After the judgment and processing of the control unit, it controls the drive motor to correct the web at the deviation position to the correct position.
1) About the principle of ultrasonic guiding sensor:
Ultrasonic sensors emit ultrasonic waves into the air to detect the presence and distance of objects by receiving reflected waves from objects. Since transparent objects can also reflect ultrasonic waves, they can be used in applications where light cannot be detected. For example, it is a sensor that can be used in a wide range of applications, such as distance measurement, conveyor belt counting, concentration flow detection, feed overlap detection, and liquid level detection.

However, if the deviation cannot be corrected in automatic mode, there may be these reasons:
1) Check whether the sensor is wired correctly;
2) Check whether the type of sensor is selected correctly on the operating system of the correction machine; Ultrasonic, optoelectric, CCD options available;
3) Check whether the polarity selection of the correction machine corresponds, the easiest way is: when the polarity is positive, the polarity can not be corrected normally, and the polarity is negative; Vice versa;
4) If the sensor is photoelectric, check if it is calibrated.
