Modular rubber plate for roller rubber coating

Abstract

The invention discloses a modular rubber plate for roller rubber coating. Mutually-matched socket and spigot joints are arranged at two ends of a rubber plate head (1) and two ends of a rubber plate tail (2). The length of the working face between the rubber plate head and the rubber plate tail is 157 mm+/-20 mm, 314 mm+/-20 mm, 471+/-20 mm, 628+/-20 mm, 785+/-20 mm or 942+/-20 mm. The socket and spigot joint (3) at the rubber plate head portion is wedge-shaped, or step-shaped or convex, and the socket and spigot joint (4) at the rubber plate tail portion is inverted-wedge-shaped, or inverted-step-shaped or concave and is matched with the socket and spigot joint at the head portion. A soft rubber layer (5) is arranged on the bonding face of the rubber plate. The anti-stripping performance of the roller rubber plate is improved, cutting is not needed, construction is convenient, and quick roller rubber coating in a field can be achieved.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a modular rubber sheet used for drum lagging. Background technique [0002] A large number of production raw materials in industries such as thermal power, mining, cement, metallurgy, coal, chemical industry, and ports are transported using rubber belt conveyors. The rubber belt conveyor is composed of a roller, a rubber conveyor belt, a motor, a transmission mechanism, a steel structure frame, and a buffer device. The surface of the roller is covered with rubber to protect the metal roller from wear and tear, and at the same time increase the friction between the roller and the rubber conveyor belt to prevent the conveyor belt from slipping and improve the operating efficiency of the equipment. However, the roller rubber will wear and fall off after a long time of operation, and if it is not replaced in time, it will affect the normal operation of production. [0003] At pres...

Problems solved by technology

When the roller rotates to drive the rubber conveyor belt to move, the vertical section of the front head of the rubber sheet on the surface of the roller is susceptible to the reaction force exerted by the rubber conveyor belt and opposite to the moving direction of the roller. The head of the rubber sheet begins to peel off; coupled with the penetration and intrusion of moisture, dust, and particulate materials into the joints of the two rubber sheets, the peeling tendency of the rubber sheet is increased, and it is easy to cause the rubber sheet to fall off the surface of the drum quickly.

With the current "cold vulcanization" lagging method, if you want to reduce the number of rubber plate joints and reduce the tendency of the joints to peel off, you have to use a large rubber plate to wrap the drum. Due to the limitation of the narrow space between the upper and lower rubber conveyor belts on site, the rubber must be removed. Conveyor belts, which will increase the labor intensity of workers and prolong production downtime, making it impossible to achieve online rapid lagging construction

In addition, the current "cold vulcanization" lagging method cuts the lagging rubber sheet on site according to the diameter of the drum, which will inevitably produce a large amount of leftovers, which will increase the cost and waste a lot
