Description

Technical Field

[0001] The utility model belongs to the technical field of steel coil processing, and particularly relates to a cold-rolled steel coil unwinding mechanism. Background Art

[0002] Cold-rolled steel strip is made by rolling hot-rolled coils at room temperature below the recrystallization temperature. Among them, those with a long length and delivered in coils are called steel coils. Cold-rolled steel has good properties. That is, through cold rolling, cold-rolled strip steel with a thinner thickness and higher precision can be obtained, which has the characteristics of high flatness, high surface finish, easy coating processing, etc. At the same time, it has high stamping performance, non-aging, and low yield point. Therefore, cold-rolled sheets have a wide range of uses. They are mainly used in industries such as automobiles, printed iron drums, construction, building materials, bicycles, etc. At the same time, they are also the best choice for producing organic coated steel sheets.

[0003] Steel coils need to be unwound during production or processing. Due to the characteristics of heavy weight, easy rolling, and high surface protection requirements of steel coils, in the prior art, the loading and unloading of steel coils are generally carried out by a lifting forklift. The lifting rod of the forklift needs to extend into the steel coil and then lift the steel coil to unload the material. However, when the steel coil is on the steel coil support of the unwinding mechanism, the space in contact with the lifting rod is limited, which brings certain difficulties to the forklift unloading, and is also easy to damage the steel coil, causing unnecessary waste and increasing the production cost.

[0011] As a further improvement of the utility model, a hand wheel is coaxially arranged at the outer end of the rotating shaft, and is coaxially connected with the clutch.

[0012] As a further improvement of the utility model, the steel coil support is of a cylindrical structure, the push plate includes a connecting part and an annular part, and the annular part is arranged outside the steel coil support.

[0013] As a further improvement of the present utility model, a first limiting step and a second limiting step are provided on the main shaft.
