The aluminium coil slitting has high requirements on the shape of the aluminum coil, and the ruffle defect that is easily generated by the aluminum roll is eliminated in the slitting process of the slitting machine. In the production of aluminum coil slitting, every time there is a lotus leaf edge defect, the tool or flattening roller must be readjusted, and the shape of the aluminum roll must be redrawn every time it is adjusted, which not only affects the production efficiency but also reduces the yield, and once the lotus leaf appears side rolls cannot be used as qualified products. Therefore, the various surface quality problems in the aluminum coil slitting process are solved one by one, ensuring that the surface of the finished aluminum coil is smooth and free of burrs.
The length, width and weight of the slitting machine shall be determined according to relevant standards. The performance and technology of slitting is superior, mainly in the following aspects:
First, the equipment is advanced in technology, mainly in the use of shaftless unwinding for raw materials, photoelectric rectifying air brake method, and independent center winding for winding, equipped with There are two friction reels up and down. The rewinding reel adopts a special structure and is assembled from airbag felt strips and many friction rings. The winding paper core is fixed on the friction ring, and there is no contact pressure between the friction rings, which can ensure that multiple rolls of aluminium coils products are wound on the same shaft. The control system of the slitting machine adopts the latest PLC and touch screen, and has automatic control functions such as inertia and friction air pressure calculation of working speed and winding tension characteristic curve calculation. When PLC calculates the winding tension, factors such as diameter, speed, and moment of inertia are comprehensively considered, which can ensure accurate and stable tension control, and has a fault display function, which is easy to operate. Secondly, the cutting speed is high, the cutting speed is as high as 300 ~ 400m/min, and it is equipped with a special unloading device, which is convenient for loading and unloading, saving time, high production efficiency and high degree of automation. The operation of the slitting machine is basically completed on the touch screen, with good repeatability, eliminating the influence of human factors such as operator's experience and skills. One machine has a variety of uses. About 20,000 winding tension diameter characteristic curves and winding tension speed characteristic curves are stored in the machine to choose from. After selecting the warp sheet and setting various parameters, the winding tension is automatically controlled. Therefore, the machine has a wide range of adaptability, in addition to aluminium coil slitting, it is also suitable for slitting aluminum foil to meet the needs of different slitting products.
