Strip steel is coiled, when thick plate coiling is the main working condition, a coiling machine coiling drum mostly adopts a coiling drum with a jaw, and the coiling is not assisted by a coiling aid at the moment; when the sheet is coiled to be a main working condition, a rectangular pyramid sector winding drum is generally selected, and a coiling aid is needed to assist in coiling for 3-5 circles. At present, the thickness change range of a set of coiling system applicable to strip steel is small. CN110170544A and CN110814084A disclose a take-up device, respectively.
In the rolling production of strip steel, the requirements on multiple purposes, strong adaptability and the like of one machine are higher and higher, so that a set of coiling system is required, and the rolling thickness and strength change range of the applicable steel plate is larger and larger.
However, often the drum with jaws, to which the thick plate can be well adapted, is no longer suitable for thin plates for two main reasons: firstly, due to the existence of gaps among the fan-shaped plates of the winding drum and jaws, the inner ring of the finished steel coil can generate indentation, and the surface quality and yield of the strip steel are influenced; secondly, as the thickness of the steel plate is reduced, the stability and uniformity of clamping become poor, and even the clamping can not be carried out or the steel plate is partially torn.
Similarly, for the light coiler suitable for coiling the thin plate and the matched light coiler, because of the limitation of insufficient coiling assisting capability and rigidity strength of the thick plate, the thick plate is not easy to be reliably wound and attached on the surface of the coiling drum, and the coiling process is unstable.

Under the general condition, when the thickness of the plate strip is not changed greatly, the tension change range is smaller, the gradient reduction of the tension is generally realized without using a tension roller, the plate strip enters a coiling system through a single channel, and the coiling channel does not need to be switched according to the incoming material condition and the process requirement.
