The electrical signal generated by the photoelectric guiding device is processed by CNC, programmable logic controller PLC, control system, etc. These sensors are used primarily in machine tools, material processing, motor feedback systems, and measurement and control equipment. The conversion of angular displacement in the web guiding system adopts the principle of photoelectric scanning. The reading system is based on the rotation of a radial graduated disk consisting of alternating light-transmitting and light-tight windows. The system shines all vertically with an infrared light source, so that the light projects the image on the disk onto a receiver surface, which is covered with a grating, called a collimator, which has the same window as the optical disk. The job of the receiver is to sense the light changes produced by the rotation of the disc and then convert the light changes into corresponding electrical changes. Generally, the rotary encoder can also get a speed signal, and this signal needs to be fed back to the frequency converter to adjust the output data of the frequency converter.

The signal output end of the web guiding sensor is connected to the control signal input end of the correction gas-liquid servo valve. The liquid inlet and outlet of the guide gas-liquid servo valve are connected to the oil cylinder through pipes. The push rod of the oil cylinder is connected to the guiding mechanism. The web guiding sensor is fixed on the sensor bracket. , there is a connecting ring at the end of the sensor bracket, the connecting ring is put on the sensor lateral displacement adjustment rod, and is fixed with the sensor lateral displacement adjustment rod through a jackscrew, the segmentation machine is corrected and connected to the slide with a pulley at the bottom. There is a fixed rod on the sliding seat, and the fixed rod is detachably connected to the raw material center drum. A photoelectric guiding system is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disc and the latter is called a code ruler. According to the readout method, the photoelectric guiding device can be divided into two types: contact type and non-contact type; according to the working principle, the encoder can be divided into two types: incremental type and absolute type.

The electric guiding device is an edge position detection device (EPC). It is a system that controls the horizontal position deviation of thin soft materials during transportation. It has functions such as automatic detection, automatic tracking, and automatic adjustment. It can track and correct the marking lines or edges of paper, film, self-adhesive tape, aluminum foil and other materials to ensure neat winding and cutting. This system can be used in light industry, textile, printing and dyeing, printing and other industries.
