At this time, the distance value between the two clamping rods is a. When the roller rotates to the short diameter and contacts the two clamping rods, the two clamping rods will be separated to the minimum distance. At this time, the distance value between the two clamping rods is b.

[0017] In the actual detection process, it is difficult to accurately determine the values ​​of a and b. In order to measure the values ​​of a and b more accurately, during the rotation of the roller, the infrared ranging sensor records the current distance between the two clamping rods every 0.1 second, and sends the data to the electric control cabinet for recording and comparison. After 1 minute of roller rotation, the electric control cabinet compares the maximum value between the two clamping rods as a and the minimum value as b. By dividing b / a, the ellipticity of the roller is obtained. The smaller the ratio, the greater the ellipticity of the roller; the larger the ratio, the smaller the ellipticity of the roller.
