Problems solved by technology

[0004] Due to the point contact, the service life of the rubber roller is reduced, and the contact point is easy to be ground;
[0005] After the steel plate rubs against the rubber roller, rubber wear debris falls off and sticks to the steel plate, causing quality problems of the steel plate product

Embodiment 1

[0021] according to Figures 1 to 2 , the present invention provides a particle rubber roller, comprising a roller body 1, the surface of the roller body is coated with a rubber layer 2, the outer surface of the rubber layer is a smooth curved surface, and the rubber layer is composed of base rubber 3 and several rubber particles 4, The rubber particles are evenly distributed in the base rubber, and the Shore hardness of the rubber particles is 15 degrees higher than that of the base rubber. The particle size of the rubber particles can be appropriately changed according to the change of the distribution density of the rubber particles on the rubber layer.

[0022] A method for manufacturing a granular rubber roller, comprising the following steps:

[0023] a. To manufacture semi-vulcanized rubber granules, add the rubber granules into the molten base rubber and mix them evenly;

[0024] B, forming the mixture of the rubber particles obtained in step a and the base rubber in...

Abstract

The invention discloses a particle rubber roll and a manufacturing method thereof. The particle rubber roll comprises a roll body, wherein a rubber layer coats the surface of the roll body, the outer surface of the rubber layer is a smooth arc-shaped surface, the rubber layer consists of base rubber and a plurality of rubber particles, the rubber particles are uniformly distributed in the base rubber, and the shore hardness of the rubber particle is 15 degrees more than the shore hardness of the base rubber. The particle rubber roll has the advantages that the rubber layer is made of two kinds of rubber material with different hardness; when the particle rubber roll is in contact with a steel plate, the friction coefficient of the surface of the rubber layer is increased because of hardness difference, and the slippage and expansion losing are avoided; as the rubber layer is in surface contact with the steel plate, the easiness in generation of rubber powder falling is avoided, the influence on the quality of the rubber layer caused by the rubber grinding chips falling onto the steel plate is avoided, and the service life of the rubber roll is longer.

Description

technical field [0001] The invention relates to the technical field of cold-rolled steel plate manufacturing, in particular to a granular rubber roller and a manufacturing method thereof. Background technique [0002] There are a large number of intermediate transition rubber rolls such as tension rolls, steering rolls, and looper rolls on the units of steel enterprises producing cold-rolled steel plates. Such as: hot-dip galvanizing, hot-dip tinning, continuous annealing, color plating units, etc. Generally, the surface shape of this rubber roller is a flat roller. Since the steel plate needs to be carried out under a relatively large tension during the production of cold-rolled plates, it is easy to cause the rubber roller to slip and lose its expansion, resulting in equipment failure of the unit. [0003] To solve slipping and loss of inflation, the conventional method is to treat the surface of the rubber roller with orange peel, increase the roughness, and prevent sli...
