[0002] Chemical fiber paper tubes are used in the processes of spinning, winding, etc. During use, the chemical fiber paper tubes need to be installed on a rotating shaft and run at high speed. During use, the wear of the chemical fiber paper tubes is inevitable. When the wear is serious, the paper tubes need to be replaced. Therefore, the wear resistance of the chemical fiber paper tubes determines their service life. During the processing of chemical fiber paper tubes, the paper tubes need to be polished, chamfered, etc. During the processing, jigs are needed to clamp the paper tubes and run at high speed. The existing jigs are generally inner support type jigs, and the way of clamping the paper tubes is similar to the actual use process of the paper tubes.
