Product Description

Guaranteed Quality Metal Sheet Decoiler Leveling And Cut To Length Machine Unwinding and Leveling Machine: An Efficient Solution for Sheet Metal Processing
The Unwinding and Leveling Machine is a revolutionary equipment designed to streamline the sheet metal processing operations in factories specializing in thin plates. This machine offers a seamless and cost-effective solution for transforming coiled galvanized steel into precisely leveled sheets ready for further processing.
The hydraulic unwinding mechanism of this machine smoothly unfurls the galvanized steel coils. The expanded coils are then precisely fed into the leveling device via a sophisticated feeding system. The leveling device is equipped with numerous rollers. By adjusting the distance between the upper and lower rollers, the steel coils are accurately flattened to meet the desired flatness standards.
The final stage of the process involves a mechanical shearing machine for cutting. This shearing machine operates at a high speed, ensuring efficient and rapid cutting of the leveled sheets.
One of the significant advantages of investing in this Unwinding and Leveling Machine is the potential for reduced production costs. By using steel coils as the raw material, factories can benefit from several cost-saving factors. Firstly, steel coils have a smaller volume, which leads to lower transportation costs. Secondly, the price of steel coils is typically more economical compared to steel plates.
In conclusion, the Unwinding and Leveling Machine is an excellent choice for factories engaged in the processing of thin plates. It not only enhances productivity but also offers substantial cost savings, making it a valuable addition to any sheet metal processing facility.

Major component
1. Uncoiling machine: located at the front end of the production line, responsible for rolling the coiled metal coil smoothly. It is usually equipped with an automatic centering device to ensure accurate alignment of materials during development.
2. Primer device: located after the uncoiler, it is used to guide the unfolded material into the straightening part to maintain the continuity and stability of the material.
3. Straightening mechanism: composed of a number of straightening rollers arranged up and down, these rollers can adjust the pressure according to the need to gradually remove the corrugated and bending of the surface of the material to achieve the flatness of the plate. The number and diameter of rollers are designed according to the thickness and hardness of the machined material4. Cutting unit: If necessary, the leveling machine can be configured with an automatic cutting device to accurately cut the flat sheet according to the set size. There are many types of cutting methods, such as flying shear and pendulum shear, which can achieve fixed length or indefinite length cutting.
5. Stacking and packing system: After cutting, the sheet is transported to the stacking area through the conveying device, and then packaged or loaded directly for easy storage and transportation.
