An embedded chamber 207 is opened at the middle position of the inner side of the rolling roller 1, and a grinding sheet 208 is bonded to the top of the top grinding slider 206. A fixing rod 20 is welded to one end face of the top grinding slider 206. 9. There are two groups of fixing holes 204, which are symmetrically opened on the inner side of the rolling roller 1. The fixing screw 211 passes through the fixing rod 209 and is threadedly connected to the inner side of the fixing hole 204, which is conducive to fixing the top grinding slider 206. The bottom grinding block 210 is installed on the inner side of the rolling roller 1 at a position symmetrical to the top grinding block 203. The inner side of the fixing rod 209 is threadedly connected with the fixing screw 211. The bottom grinding slider 212 is installed on the inner side of the rolling roller 1 at a position symmetrical to the top grinding slider 206, and the drive shaft 213 is embedded in the inner side of the embedded chamber 207.

[0033] The outer side of the driving shaft 213 is equipped with a lifting assembly 3;

[0034] The lifting assembly 3 includes a rotating sleeve 301, a bearing 302, a lifting slide 303, a motor base 304, a servo motor 305, a sliding base 306, a hydraulic rod 307 and a base 308;

[0035] The outer side of the driving shaft 213 is sleeved with a bearing 302, and the outer side of the bearing 302 is sleeved with a rotating sleeve 301. A lifting slide 303 is welded at the bottom position of the outer side of the rotating sleeve 301, and a motor seat 304 is welded to one end face of the lifting slide 303. A servo motor 305 is installed on the inner side of the motor seat 304.

A base 308 is installed at the bottom end of the sliding base 306.

[0036] The working principle and use process of the present invention are as follows: First, when the operator needs to roll the thickness of the head of the steel strip, the operator moves the rolling roller 1 to the top position of the conveyor belt of the steel strip. At this time, if it is necessary to roll the steel strip without rust, the operator can reduce the thickness of the steel strip by rotating the rolling roller 1. When it is necessary to roll the steel strip with rust on the surface, the operator can pull out the fixing screw 211 from the corresponding fixing hole 204, and at the same time take out the top rolling block 203 and the bottom rolling block 210 from the inner side of the clamping groove 202. At this time, under the action of the reset spring 205, the top grinding slider 206 and the bottom grinding slider 212 will pop outward, and the grinding sheet 208 will be bounced back to the same arc surface as the rolling roller 1. At this time, the fixing screw 211 is passed through the fixing rod 209 and fixed to the inner side of the corresponding fixing hole 204, thereby fixing the top grinding slider 206 and the bottom grinding slider 212. Then the operator controls the rolling roller 1 to rotate. At this time, when rolling the rusted area, the rolling roller 1 is controlled to rotate two more circles, so that the rust can be polished. The steel strip can be polished and rolled at the same time through one device, ensuring that rust spots will not remain on the top of the strip, thereby ensuring that the surface thickness of the strip head is uniform, further improving the quality of the strip, and facilitating the finish rolling of the strip.

[0037] Next, when processing strip steel of different thicknesses, the operator controls the hydraulic rod 307 to lift and lower, thereby driving the lifting slide rod 303 to slide on the inner side of the sliding base 306, and can adjust the distance between the rolling roller 1 and the strip steel. Then, the servo motor 305 on the inner side of the motor base 304 is controlled to rotate, and then the drive shaft 213 is driven to rotate on the inner side of the bearing 302 by the servo motor 305, and then the rolling roller 1 is driven by the drive shaft 213 to process the strip steel, which is convenient for processing strip steel of different thicknesses and expands the scope of use of the convenient lifting device.
