Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fiber detection, and specifically discloses a rapid sampling tool for detecting the density of glass fiber yarns. Background Art
[0002] In the production process of traditional glass fiber yarns, parameters such as the density and combustible content of the yarns need to be measured. Generally, the method for measuring the density of yarns is as follows: first, tighten the yarn, cut a section of the yarn from the middle, then place the sample on a balance to weigh the initial weight, then place the sample in a crucible for burning, take it out and cool it, and then weigh the weight after burning. Finally, the density of the glass fiber yarn can be calculated based on the weights measured before and after.
[0003] Currently, in the prior art, a winding machine is used to wind glass fibers, then the yarn is cut and sampled, and finally the density of the glass fiber yarn is calculated by weighing. However, the winding machine winds the yarn through a rotating wire frame, and the yarn is cut and sampled manually. The lengths of the yarns cut and sampled are different. After each cutting and sampling, it is necessary to manually fix the yarn on the wire frame again, which is inconvenient to operate and reduces the work efficiency.
[0004] Therefore, it is necessary to develop a rapid sampling tool for detecting the density of glass fiber yarns to overcome the above technical problems. Summary of the Utility Model
[0005] The technical solution adopted by the utility model is as follows:
