Glass fiber cloth wrapping machine
Technical Field
The invention relates to the technical field of glass fiber cloth processing, in particular to a glass fiber cloth wrapping machine.
Background
The glass fiber is an inorganic non-metallic material with excellent performance, has various varieties, has the advantages of good insulativity, strong heat resistance, good corrosion resistance and high mechanical strength, but has the defects of brittleness and poor wear resistance. Glass fibers are commonly used as reinforcing materials in composite materials, electrical and thermal insulation materials, circuit substrates, and other various fields of the national economy. The glass fiber cloth is a plain weave fabric of twistless roving and is an important substrate for manually pasting the glass fiber reinforced plastic. The strength of the checkered cloth is mainly in the warp and weft directions of the fabric, and unidirectional cloth can be woven for occasions requiring high warp or weft strength, and more untwisted roving, single-warp cloth and single-weft cloth can be arranged in the warp or weft direction. The glass fiber cloth is mainly used in the hand pasting process, and the glass fiber reinforced material checkered cloth is mainly used in ship bodies, storage tanks, cooling towers, ships, vehicles, tanks and building structural materials. Glass fiber cloth is used industrially mainly for: heat insulation, fire prevention and flame retardance. The glass fiber cloth is often wrapped outside the pipeline, and plays roles in heat insulation, fire prevention and flame retardance. At present, a plurality of pipelines are wound, and glass fiber cloth is wrapped outside the pipelines, so that the labor intensity of workers is high, and the efficiency is very low. At present, no equipment capable of automatically wrapping glass fiber cloth exists in the market.
