Description

Technical Field

[0001] The utility model relates to the field of uncoilers, and specifically relates to a cold-rolled strip steel uncoiler. Background Art

[0002] Cold-rolled strip steel refers to a steel product that uses hot-rolled strip steel and steel plates as raw materials and is rolled into strip steel and thin plates by a cold rolling mill at normal temperature; cold-rolled strip steel has the advantages of good surface finish, good flatness, high dimensional accuracy, and excellent mechanical properties.

[0003] The uncoiler is the first process equipment on the cold-rolled strip steel production line, mainly responsible for smoothly unwinding the steel coil and leading out the head of the strip steel so that it can smoothly enter the subsequent rolling or processing process. During the cold rolling process, the strip steel needs to maintain a certain tension to ensure the stability of rolling and the quality of the product.

[0004] The existing uncoilers usually directly unwind the steel coil when uncoiling cold-rolled strip steel. It is found in production and observation that the cold-rolled strip steel will shift during the moving process, which will cause deviation in the transportation position of the cold-rolled strip steel, and further affect the subsequent processing of the cold-rolled strip steel.
