Application of printing roller with improved material performance

Abstract

The invention relates to the application of a printing roller with the improved material performance. A glass-fiber reinforced plastic (GFRP) or a carbon-fiber reinforced plastic (CFRP) serves as a substrate material of the printing roller, and then silicon dioxide, nanometer aluminum oxide or ceramic powder are doped into resin. The printing roller provided by the invention is light in weight, and easy to mount and dismount; the requirements for the design of associated equipment is simpler and more convenient, the thickness of an equipment supporting wall plate and the wall plate consumptionare reduced, the roller body rotating inertia is low, the vibration resistance is high, and the roller rotating speed can be improved; compared with a roller of which the substrate is made of steel or aluminum, the printing roller is higher in strength and lower in deflection; the printing roller can be driven under the relatively low motor power; the sleeve roller surface is high in hardness, resistant to scraping, low in corrosion possibility, and longer in service life; and the production process is simple and convenient, the cost is low, and the application prospect is good.

Description

technical field [0001] The invention belongs to the field of rollers, in particular to the application of a printing roller with improved material properties. Background technique [0002] The roller is a cylindrical part, which is divided into driving roller and driven roller according to the purpose; according to the driving mode, it is divided into power roller and non-power roller, and the power roller is divided into single sprocket roller, double sprocket roller, Single O-belt roller, multi-O-belt roller, servo motor direct drive; unpowered rollers are divided into internal tooth shaft rollers and spring-pressed rollers. According to the structure, it can be divided into cylindrical roller and tapered roller. [0003] The traditional roller material base is steel, which has the disadvantages of heavy weight, difficult loading and unloading, unsuitable high speed and large rotational inertia. [0004] Recently, aluminum substrates and polyurethane substrates have been...

Problems solved by technology

[0003] The base material of the traditional roller is steel, which has the disadvantages of heavy weight, difficult loading and unloading, unsuitable for high speed, and large rotational inertia

[0004] Recently, aluminum substrates and polyurethane substrates have been developed in some fields. These two substrate materials are not wear-resistant, easy to deform, have low strength, and are prone to corrosion when in contact with chemical media; however, the production process of polyurethane substrates is complicated, and equipment investment costs High, and not conducive to environmental protection
