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

Embodiment 1

[0019] Glass fiber reinforced plastic (GFRP) is used as the base material of the flexographic printing plate sleeve, and then the mixed resin mixed with silica powder and epoxy resin is evenly painted on the surface of the roller, and then ground to The size is required, and after polishing the roller surface of the sleeve, the flexographic printing plate sleeve can be obtained.

[0020] The measured hardness of the roller surface reaches Shore D 89 degrees, which has a high resistance to knife scratches.

Embodiment 2

[0022] Use carbon fiber reinforced plastic (CFRP) as the base material of the smooth roller, and then evenly paint the mixed resin mixed with nano-alumina liquid and phenolic resin on the surface of the roller, and then grind it to the required size, and then grind the roller surface After polishing treatment, a smooth roller can be obtained. The smooth roll includes paper, film, non-woven fabric, aluminum foil, lithium battery film, graphene film, textile, printing and dyeing, chemical industry and other industries guide roll or pressure roll application.

[0023] The measured hardness of the roller surface reaches Shore D 98 degrees, with high wear resistance.

[0024] Roller of the present invention compares with the performance parameter of existing roller:

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...
