Composite material ground roller shaft core

Abstract

The invention provides a composite material ground roller shaft core and belongs to the field of shaft cores. A plurality of supports are arranged between an inner cylinder and an outer cylinder in a spiral shape, the inner cylinder and the outer cylinder are both in a cylinder shape, the supports are plate-shaped spiral rotating ribs, the plate-shaped spiral rotating ribs extend in a spiral form between the inner cylinder and the outer cylinder, and the two ends of each plate-shaped spiral rotating rib are connected with the inner cylinder and the outer cylinder at the same time to form a whole. The supports extend in a spiral form between the inner cylinder and the outer cylinder, and the inner cylinder and the outer cylinder are connected into a whole through the spiral supports; a plurality of spiral support points are formed on the line, parallel to a shaft, on the inner wall of the outer cylinder of the shaft core, so that the wall of the outer cylinder is supported between the inner cylinder and the outer cylinder, and the strength of the shaft-cylinder-shaped shaft core is greatly improved; the shaft core is light, small in rotary inertia and high in outer cylinder precision, does not deform and requires no straightening, and a formed ground roller using the shaft core has no mechanical wave and is capable of resisting static electricity, corrosion and high temperature; the one-off forming of the ground roller is achieved, the preparation steps are reduced, energy conservation and consumption reduction are achieved, the manufacturing cost and the maintenance cost are low, and the shutdown time is short. The shaft core is integrally manufactured through 3D printing.

Description

technical field [0001] The present invention relates to a shaft core, in particular to a roll shaft core of composite material. 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 from re...
