Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber paper tubes, and in particular relates to an explosion-proof chemical fiber paper tube. Background Art

[0002] Chemical fiber paper tubes are paper tubes used for chemical fiber spinning, stretching and other winding. In the production process of chemical fiber paper tubes, it is necessary to unwind single-layer paper, and then use glue to compound multiple layers of paper to form multiple layers of paper and then wind them to obtain paper tubes, and finally cut them into small sections of chemical fiber paper tubes. Chemical fiber paper tubes need to rotate at high speed with the shaft when in use. Once the paper inside the paper tube has poor adhesion, the chemical fiber paper tube rotating at high speed will burst. The burst of chemical fiber paper tubes rotating at high speed will not only cause production interruption, cause loss of silk thread, etc., affect production efficiency, but also may cause harm to nearby operators and cause safety accidents. With the continuous updating and upgrading of spinning equipment, production efficiency continues to improve, and the rotation speed of chemical fiber paper tubes is also getting faster and faster. Therefore, it is necessary to design new anti-burst chemical fiber paper tubes that can meet the needs of high-speed rotation. Summary of the invention
