At the front end inside the box body 1, a motor 14 is fixedly arranged. The output end of the motor 14 is fixedly connected to the rear end of the rotating rod 13. By driving the rotating rod 13 to rotate through the motor 14, the rotating rod 13 drives the threaded rod 2 to rotate, and the threaded rod 2 drives the external winding roller 3 to rotate, thereby realizing the winding of the strip steel.

[0031] A counterweight block 15 is fixedly arranged inside the box body 1 to increase the stability of the box body 1.

[0036] Working principle:

[0037] When in use, according to the thickness and width of the strip steel to be wound, first start the double-shaft motor 16. The double-shaft motor 16 drives the cross bars 17 at both ends to rotate. The cross bars 17 drive the first belt pulleys on the rod walls to rotate. The first belt pulleys drive the second belt pulleys to rotate through the belts. The second belt pulleys drive the first bidirectional lead screw 8 to rotate. The first bidirectional lead screw 8 drives the two moving blocks 9 threadedly connected to the rod walls to move. The moving blocks 9 drive the adjusting plates 10 and the limiting wheels 12 on the lower side walls to move horizontally. By rotating the rotating block 19, the rotating block 19 drives the second bidirectional lead screw 18 on the side wall to rotate. The second bidirectional lead screw 18 drives the adjusting block 11 threadedly connected to the rod wall. Thus, the adjusting block 11 drives the limiting wheels 12 on the side walls to move up and down, realizing cooperation with strip steel of different thicknesses. Fix one end of the strip steel outside the winding roller 3. By starting the motor 14, the motor 14 drives the rotating rod 13 at the output end to rotate. The rotating rod 13 drives the threaded rod 2 to rotate. The threaded rod 2 drives the external winding roller 3 to rotate. Thus, the strip steel is wound under the limiting action, which is safer and will not cause the situation of swinging and hurting people.
