The photoelectric deviation correction device controller is an automatic control system that controls and corrects the positional deviation of thin materials during high-speed transmission. It has functions such as automatic detection, automatic tracking, and automatic deviation correction. It can track and correct the deviation of the mark line or edge of paper, film, adhesive tape, aluminum foil, steel strip, and other materials to ensure neat winding and slitting.
The photoelectric deviation correction device controller is an automatic control system that controls and corrects the positional deviation of thin materials during high-speed transmission. It has functions such as automatic detection, automatic tracking, and automatic deviation correction. It can track and correct the deviation of the mark lines or edges of paper, film, adhesive tape, aluminum foil, steel strip, and other materials to ensure neat winding and slitting.
The photoelectric deviation correction controller uses a general-purpose photoelectric deviation correction sensor for both edges and lines, supplemented by imported drive devices and high-precision drivers, to control the roll material and keep its edges and lines at the specified position at all times.
This equipment is simple to operate, high in precision, stable, and widely applicable. It is suitable for different materials such as black, mirror, white, and transparent films, paper, cloth, and aluminum foil, and can be used in various printing machinery, such as printing machines, laminating machines, coating machines, slitting machines, embossing machines, inspection machines, paper machines, bag-making machines, and dyeing and finishing machines.
Traditional hydraulic deviation correction:
1. Due to leakage in hydraulic transmission and the compressibility of the liquid, the transmission cannot guarantee a strict transmission ratio. Hydraulic deviation correction is sensitive to changes in oil temperature and is not suitable for operation at high or low temperatures. The low-speed self-priming function of the gear pump is poor; the gear pump usually operates at speeds above 1450 rpm. The solvent efficiency of the gear pump decreases sharply when the speed is reduced, and the internal leakage increases significantly.
Especially in summer, when the ambient temperature is high and the viscosity of the hydraulic oil decreases, some gear pumps will idle and fail to establish oil pressure, and the system cannot work effectively. In winter, the gear pump is prone to oil suction failure and shaft end leakage. Due to the increased oil viscosity, the oil pump cannot suck oil. Under vacuum suction, air is drawn into the shaft end from inside the pump, rendering the system ineffective.
2. It is difficult to find the cause when a hydraulic transmission malfunction occurs.
3. Low hydraulic precision, with a maximum error of 2 millimeters.
4. High operating costs (high power consumption).
The above is an introduction to the differences between photoelectric deviation correction devices and traditional hydraulic deviation correction. Hope it helps!
