Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber unwinding mechanisms, in particular to a glass fiber unwinding mechanism with a limiting component. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. It has many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made of six kinds of minerals, namely pyrophyllite, quartz sand, limestone, dolomite, colemanite and magnesia borax, through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is from several microns to more than twenty microns, which is equivalent to 1 / 20-1 / 5 of a hair. Each bundle of fiber strands is composed of hundreds or even thousands of single filaments. Glass fiber is usually used as reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other fields of the national economy.

[0003] When processing glass fiber, the monofilament is wound on the reel, and then the reel is placed in the wire-releasing mechanism. The monofilament is combined by the yarn collector and then reeled. When the reel of the traditional glass fiber wire-releasing mechanism is put on the reel positioning rod for wire-releasing, there is generally no limit component on the top, which leads to the reel being easily pulled up during high-speed wire-releasing, resulting in reduced wire-releasing stability. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
