The steel strip coil can only be loaded and unloaded after being disassembled. In order to improve the loading and unloading efficiency of the steel strip coil, the present application provides a steel coil unwinding rack that can be quickly loaded and unloaded.

[0012] A movable cylinder is fixedly connected to the support plate, and an output end of the movable cylinder slides through the rotating sleeve and is fixedly connected to the threaded rod;

[0013] A sleeve body, rotatably sleeved on the threaded rod;

[0014] A plurality of rotating rods have one end which is rotatably arranged on the sleeve body, and one end of the rotating rod which is away from the sleeve body is rotatably connected with one end of the clamping plate at the corresponding position which is away from the slide plate.

[0015] Preferably: a nut and a threaded sleeve are connected to the threaded rod through threads, and the threaded sleeve and the nut are respectively located on two sides of the sleeve body;

[0016] Preferably: the extension plate has movable holes distributed along the radial direction of the rotating plate, and the slide plate is

[0017] The slide plate is in an I-shape, passes through the moving hole and is slidably connected to the moving hole, and a locking bolt is threadedly connected to the wing plate of the slide plate.

[0018] The beneficial effects of adopting the above technical solution are:

[0019] The present application provides a movable cylinder that can drive the threaded rod and the sleeve to move, so that the sleeve drives one end of the rotating rod to move, and the other end of the rotating rod drives the clamping plate to rotate on the slide plate, so that the clamping plate can press against the inner wall of the steel strip roll, thereby fixing the steel strip roll, and the rotating sleeve can rotate on the support plate, and the sleeve can rotate on the threaded rod, so that the steel strip roll can rotate and unwind under the traction of external force.
