Description

Technical Field

[0001] The present application relates to the field of reducer technology, and in particular to a balancing bracket for a motor reducer of an uncoiler. Background Art

[0002] A cold rolling mill is a continuous production line in which a double decoiler unwinds the raw coil, a straightener eliminates bends and waves in the sheet, ensuring it is straight, and a shear cuts the sheet to the desired length and size. Cold rolling mills are widely used in industries such as steel and nonferrous metals.

[0003] However, the motor reducer base of the double uncoiler often malfunctions during operation. The motor reducer base is fixed to the double uncoiler's support structure. The fixing bolts on the motor reducer base, which drives the double uncoiler's mandrel to rotate, often break. Even after welding, the base still pulls apart. Once the bolts break or the weld opens, the base will fall off, resulting in a long downtime. The reason for the base falling off is that the mandrel speed of the double uncoiler does not match the mandrel speed of the straightener, resulting in a difference in the linear speed of the conveyed sheet. The straightener pulls on the double uncoiler's mandrel, and the double uncoiler pulls on the motor reducer base via the chain, which frequently causes the motor reducer base to fall off.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the motor reducer base is prone to falling off failure, which may lead to long-term shutdown and thus reduce the cold rolling production efficiency. Utility Model Content
