Backing roll fiber-braided composite layer

Abstract

The invention discloses a backing roll fiber-braided composite layer and belongs to a backing roll. The composite layer comprises a fiber-braided structure reinforcement layer and a pouring layer; the outside of the fiber-braided structure reinforcement layer is wrapped by the pouring layer; the fiber-braided structure reinforcement layer is a sleeve-mesh-shaped braided fabric formed by braiding a composite in a braiding machine and is single-layer or multilayer; the pouring layer is formed by wrapping an external cylinder of the fiber-braided structure reinforcement layer by using various materials through a pouring process; and the pouring layer is made of resin, rubber or polyurethane. The composite layer disclosed by the invention is braided in a reciprocated way by using the braiding machine, so that the thickness of an outer layer is increased, and the drop of the fiber-braided structure reinforcement layer is avoided; the outer cylinder is formed by pouring a special high-strength material for the backing roll; and the backing roll fiber-braided composite layer is light in weight, high in tensile strength, free of breakage at the outer layer, small in rotary inertia, high in outer cylinder precision, free of deformation, free of mechanical waves on the formed backing roll, antistatic, corrosion-resistant, high-temperature-resistant and long in life, so that the product quality is improved, and the productivity is increased.

Description

technical field [0001] The invention relates to a ground roller, in particular to a fiber braided composite layer of a ground roller. Background technique [0002] Floor rollers are widely used, and they are inseparable from printing machinery, textile machinery, mining, chemical industry, aerospace and other fields. [0003] The roller in the textile machinery is a roller-shaped transmission part installed above the driving shaft, and its function is to draft the fiber through rolling friction to facilitate weaving. However, due to the static electricity generated by the contact and friction between the ground roller and the fiber during work, part of the fibers will be adsorbed on the long circumferential surface of the ground roller, which reduces the drafting efficiency of the fiber, so that it needs to be manually removed continuously, and the work is more troublesome, which in turn causes damage to the producer. difficult. Ground rollers in other industries are far f...
