What Factors Determine The Accuracy Of The Photoelectric Corrector?

Photoelectric corrector manufacturers believe that the accuracy of the photoelectric corrector is determined by three factors: the deviation of the roll material, the accuracy of the corrective system itself, and the installation accuracy of the photoelectric corrector. Photoelectric corrector manufacturers recommend installing the corrector at the position closest to the key process, but if the end user installs what kind of machine between the photoelectric corrector and the key process, or the accuracy or parallelism of the roller shaft is not good We cannot control the accuracy of the correction. Therefore, from the perspective of the photoelectric correction supplier, the accuracy of the correction system is defined as the position accuracy of the coil just after it exits the probe.

The magnetic powder brake is a new type of transmission element that uses magnetic powder as a medium to form a magnetic powder chain to transmit torque when energized. The magnetic powder brake is mainly composed of an inner rotor, an outer rotor, an excitation coil, and magnetic powder. When the coil is not energized, the active rotor rotates. Due to the centrifugal force, the magnetic powder is thrown on the inner wall of the active rotor, there is no contact between the magnetic powder and the driven rotor, and the active rotor is idling. The electromagnetic field is generated after the DC power supply is connected, and the magnetic powder of the working medium forms a magnetic powder chain under the action of magnetic lines of force, which connects the inner rotor and the outer rotor to achieve the purpose of transmitting and braking torque.

The automatic correction control system is an AC photoelectric correction control system. The system is simple to operate and easy to install. The performance of the system in response speed, anti-interference and correction accuracy has been significantly improved compared with the previous products. The improved wiring method completely avoids the damage of the controller that may be caused by the original wiring error.

The photoelectric correction controller is a kind of high-precision differential and wobble selection correction controller that tracks the edge of the working material or printed lines; it is composed of a large-scale industrial integrated circuit, which has strong anti-interference ability in a harsh working environment and high reliability , Long service life and other advantages. To meet the needs of continuous non-stop production work in the printing and packaging industry, it has been widely used in non-woven fabrics, plastic film slitting machines, special material slitting machines, coating machines, printing machines, compound machines and other equipment. The photoelectric correction control system is composed of a correction controller, a photoelectric sensor, and a motor servo actuator.
