Photoelectric Correction VS Traditional Hydraulic Correction

The photoelectric correction controller is an automatic control system that controls the position deviation of thin materials during high-speed transmission. It has functions such as automatic detection, automatic tracking, and automatic correction. It can control paper, films, stickers, aluminum foil, and strip steel. Track and rectify the marking lines or edges of other materials to ensure the neat winding and slitting.

Photoelectricity correction controller uses edge-to-line general-purpose photoelectricity correction electric eye, supplemented by imported driving device and high-precision pusher to control the roll material and keep its edges and lines at the specified position at any time. This equipment is easy to operate, high precision, good stability, wide range of application, suitable for different materials such as black, mirror, white, transparent film, paper, cloth, aluminum foil, etc. It can be used in various printing machinery, such as printing , Laminating machine, coating machine, slitting machine, embossing machine, inspection machine, paper machine, bag making machine and dyeing and finishing machine.

光电 Our company's photoelectric correction system is developed and continuously optimized after years of research and development, based on long-term experience accumulation and feedback from actual conditions on the industrial site. It is composed of large-scale military integrated circuits. It has the advantages of strong anti-interference ability, high reliability, long service life, high accuracy (up to 0.05mm), fast speed, good stability, and raw material saving for harsh working environments.

It is also widely used in coating machines, compounding (film) machines, slitting machines, quality inspection machines, rolls of cloth in the industries of photosensitive film, insulation materials, medical tapes, plastic packaging, textiles, papermaking, printing and metal calendering. Machine, printing machine, bag making machine, artificial leather machine, wallpaper machine, metal strip rolling, galvanizing, etc.

VS hydraulic correction:
Disadvantages:
1. Due to the leakage in the hydraulic transmission and the compressibility of the liquid, the transmission cannot guarantee a strict transmission ratio. The hydraulic correction is more sensitive to changes in oil temperature and should not be operated at higher or lower temperatures:
The problem of low-speed self-priming ability of gear pumps is that the gear pumps usually operate at speeds above 1450rpm. After the speed of the gear pump is reduced, the solvent efficiency of the pump decreases sharply, and the internal leakage increases significantly. Especially in the summer when the ambient temperature is high and the viscosity of the hydraulic oil drops, there will be a part of the gear pump idling to establish oil pressure, and the system cannot work effectively. The gear pump can't suck oil in the winter and the shaft end leaks. The oil pump can't suck oil due to the increase of oil viscosity. The inside of the pump is sucked into the air from the shaft end by the vacuum suction.
2. It is not easy to find the cause when the hydraulic drive fails.
3. The hydraulic accuracy is low, and the maximum error is 2 mm.
4. High use cost (large power consumption)
