Description

Technical Field

[0001] The utility model relates to a glass fiber yarn tube fixing device and belongs to the technical field of glass fiber winding. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and is widely used. Glass fiber yarn tubes are needed in the production or spinning process of glass fiber. When in use, the glass fiber yarn tubes need to be installed on the spindle disk to drive them to rotate. However, glass fiber yarn tubes have various heights. The current fixing device cannot adjust the height of the supporting rubber column when supporting the inner hole of the glass fiber yarn tube, and cannot better adapt to various glass fiber yarn tubes. In addition, the bottom of the glass fiber yarn tube and the spindle disk are plug-in structures, and the glass fiber yarn tube is not firmly fixed, which can easily cause the glass fiber yarn tube to fall off; in addition, the upper end tube column of the glass fiber yarn tube is the same size, and the top of the glass fiber yarn tube is easy to loosen when winding the glass fiber yarn, and the top is easy to bump into during the transportation process, causing damage to the glass fiber yarn.
