Description

Technical Field

[0001] The utility model relates to the technical field of uncoilers, in particular to a steel coil feeding device for silicon steel processing. Background Art

[0002] When processing silicon steel, an uncoiler is usually used for uncoiling and feeding. The uncoiler is also called a material rack, unwinding rack, or loading rack. It is a device designed for continuous stamping processing of various metal coils. The standard uncoiler consists of a motor, a reducer, an electric box, a metal expansion tile, an expansion spindle, a material blocking A-frame, a support frame, a base, and other parts. At present, during the unwinding process of the steel strip coil by the uncoiler, a clamping wheel is usually used to hold the coil tightly for transportation. However, due to the different widths of the coils, the position where the clamping wheel is pressed is not on the center line of the coil, which may cause the two sides of the coil to be unevenly tight. At the same time, during the unwinding process, the diameter of the coil becomes smaller and smaller, making it difficult for the motor to control the unwinding speed. To this end, we provide a steel coil feeding device for silicon steel processing to solve the above problems. Utility Model Content
