Detailed Description

The invention is further described with reference to the following figures and specific embodiments. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Specific structural and functional details disclosed herein are merely illustrative of example embodiments of the invention. The present invention may, however, be embodied in many alternate forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 7, a strip steel grinding system includes a grinding mechanism including a main body portion 11, a mounting portion 12, a wiping portion 13, a grinding portion 14, and a lifting arm 15, wherein:

the body 11 is mounted on the upper part of the steel strip 5 and during the feeding of the steel strip 5 the body 11 is movable relative to the steel strip 5 on the steel strip 5 to perform the relative grinding process.

The mounting part 12 is arranged below the main body part 11, and a clamping groove is arranged on the mounting part 12.

Wiping portion 13 is fixed under installation department 12 for being used for contacting and wiping steel band 5, just be equipped with the first space 17 that is used for polishing in wiping portion 13, wiping portion 13 can set up to the closed loop structure form of ring shape, square frame shape or other shapes, so that the debris on the steel band 5 is restricted in wiping portion 13.

The grinding part 14 is arranged in the clamping groove and used for grinding the steel strip 5, when the grinding part 14 descends along with the installation part 12 and the main body part 11 and contacts the steel strip 5, along with the movement of the steel strip 5, the grinding part 14 grinds the surface of the steel strip 5, and the wiping part 13 moves along with the grinding part 14, so that after the steel strip 5 is ground by the grinding part 14, the steel strip 5 is wiped by the wiping part 13, and the defect of the steel strip 5 is observed more easily.

The central line of the grinding part 14 and the central line of the steel strip 5 are arranged at an included angle of 45 degrees, defects such as cracks on the steel strip 5 are mostly appeared in transverse stripes or vertical stripes due to the influence of the processing process, the grinding part 14 and the steel strip 5 are kept in an inclined state in the length direction and the width direction, so that when the grinding part 14 grinds the steel strip 5, the defects are not ground in the defect direction extending transversely or longitudinally on the steel strip 5, the defects are more easily exposed after being ground obliquely, and due to the non-unidirectional distribution of the defects, when the positions and the directions where the defects are likely to be distributed are different, the grinding part 14 arranged obliquely relative to the central line of the steel strip 5 can move transversely or longitudinally, the grinding part 14 can sweep a larger area to improve the grinding efficiency, when the grinding part 14 is arranged in the length extending direction or the width extending direction of the steel strip 5, when the grinding section 14 moves in the longitudinal extending direction or the width extending direction of the steel strip 5, one of the paths swept by the grinding section 14 is a path having the width of the grinding section 14 itself as the width, and thus the grinding area of the grinding section 14 is too narrow, resulting in low grinding efficiency.

Lifting arm 15 fixed connection is in on the installation department 12, just lifting arm 15 with be equipped with between the main part 11 and be used for the jacking driving piece 18 of lifting arm 15, so that lifting arm 15 is close to or keeps away from steel band 5 removes, when driving piece 18 during operation, for installation department 12, with lifting arm 15 jacking and keep away from steel band 5 and remove, when needs through 14 contact steel band 5 of portion of polishing and polish, stop driving piece 18 work, lifting arm 15 descends with installation department 12 together under the action of gravity, until 14 contact steel band 5 of portion of polishing, when needing to stop polishing, again through driving piece 18 jacking this lifting arm 15 make polishing portion 14 with 5 separation of steel band can.
