Description

Technical Field

[0002] In the production process of the cold rolling mill, the thickness gauge is an indispensable equipment. In order to test the thickness of the rolled plate of the aluminum cold rolling mill, a movable thickness gauge is installed at one end of the strip, so that the position of the thickness gauge can be adjusted according to the width of the strip, and it can be moved when in use and removed when not in use; however, the thickness gauge cannot be too far away from the strip when working, so in the production process of the rolling mill, when the strip billet breaks, the tail of the material rises and it is easy to collide with the thickness gauge, resulting in damage to the thickness gauge and failure to work normally. Therefore, a protective structure must be installed for the thickness gauge;

[0003] For example, in the prior art, the Chinese utility model with publication number: CN210188052U discloses a protective cover for a thickness gauge of an aluminum plate cold rolling mill. The overall structure of the utility model is easy to install, and can effectively protect the thickness gauge without reducing the accuracy of the thickness gauge, making it safer and more convenient to use.

[0004] However, there are still some problems when using the above-mentioned aluminum plate cold rolling mill thickness gauge protective cover. When the strip is threaded, the strip is easy to collide with the protective cover. At the least, the protective cover is deformed or damaged, and can no longer protect the thickness gauge well, and needs to be repaired or replaced. At the worst, sparks may be generated by collision, causing fire. This affects production efficiency, so we need to propose a protective plate assembly. Utility Model Content
