[0002] The production of glass mostly uses a calender, which has multiple calender rollers. Its main function is to process the molten glass into glass plates of a certain thickness. To ensure the quality of glass processing, high requirements are placed on the surface smoothness of the calender rollers. Therefore, the eccentricity of the calender rollers is often tested.

By setting up a detection component, the position where the eccentric defect occurs is marked, thereby improving the convenience of the mechanism detection mark. When the calendering roller is bent, the center line of the calendering roller will deviate. It is detected by fixing both ends. After the calendering roller is bent, the rotation center line changes. The two ends are fixed, causing it to get stuck during rotation, making the detection impossible. Utility Model Content
