Preparation method of cable protection sleeves capable of being woven, wound and pultruded by glass fibers

Abstract

The invention relates to the technical field of preparation methods of cable protection sleeves capable of being woven, wound and pultruded by glass fibers, and discloses a preparation method of the cable protection sleeves capable of being woven, wound and pultruded by the glass fibers. The preparation method comprises the following steps of installing product molds, adjusting balance of a mold sleeve and a mold core, feeding an inner-layer alkali-free glass fiber composite felt into a felt guider, and neatly wrapping a mold core rod; and then pulling out the core rod and the mold sleeve froma gap, fixing the pulled-out composite felt to a traction machine, and evenly winding alkali-free glass fiber direct yarns on the mold core rod through a winding machine. According to the preparationmethod of the cable protection sleeve capable of being woven, wound and pultruded by the glass fibers, by adopting an inner and outer layer weaving process, the circumferential rigidity is greatly improved compared with that of a traditional pipe, so that the strength and the flexibility are relatively high; and through high-precision high-temperature curing of inner and outer molds, a produced pipeline has the advantages of light weight, high impact resistance, good flexibility and convenience in production, the production efficiency is improved, the production cost is reduced, and the costperformance is high.

Description

technical field [0001] The invention relates to the technical field of preparation methods of glass fiber braided and pultruded cable protective sleeves, in particular to a preparation method of glass fiber braided and pultruded cable protective sleeves. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information and wire products that realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also referred to as cables for short. In a narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts ; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. [0003] At present, the preparation of glass fiber braided and pultruded cable protective sleeves is cumbersome to operate, and the production efficiency is low, whi...
