The pressing roller 17 and the supporting roller 14 are arranged in a staggered manner. A driving member for driving the lifting frame 16 is arranged on the outside of the lifting frame 16. The driving member includes a through groove 8 vertically opened on the side wall of the drying chamber 2, and a mounting head 9 is slidably arranged inside the through groove 8. The mounting head 9 is fixedly connected to the middle of the lifting frame 16, and an electric push rod 12 is vertically installed between the bottom of the outer side of the mounting head 9 and the outer wall of the bottom end of the drying chamber 2, and an exhaust structure is arranged above the drying chamber 2.

[0018] By arranging the supporting rollers 14 and the pressing rollers 17, the steel strip can be wound in an S shape. At the same time, driven by the contraction of the electric push rod 12, the mounting head 9 will slide downward inside the through groove 8, thereby driving the lifting frame 16 to move downward, causing the pressing rollers 17 to pull the steel strip, thereby increasing the conveying length of the steel strip in the drying chamber 2, improving the drying time of the dried steel strip, and ensuring the drying quality. When the pressing rollers 17 move up to the highest point, it is convenient for the staff to wind the steel strip in an S shape.
