Embodiment Construction

[0031] A method for repairing damaged rubber conveyor belts is carried out in accordance with the following steps:

[0032] a. Grinding: Firstly, use an angle grinder to polish and roughen the area within 5-20 cm around the damaged part of the conveyor belt, and then polish and roughen the bonding surface of the repair strip with an angle grinder;

[0033] b. Chemical treatment of the surface of the conveyor belt: use rubber treatment agent for treatment, apply the rubber treatment agent evenly on the surface of the polished conveyor belt, and dry it;

[0034] c. Glue brushing: Apply the adhesive evenly on the treated surface of the conveyor belt and the repair strip;

[0035] d. Heating to activate adhesiveness: Heat the conveyor belt and repair strip to 50°C-120°C with a heating device and keep it for 2-5 minutes;

[0036] e. Bonding: In a hot state, that is, when the temperature is above 50°C, quickly attach the adhesive surface of the repair strip to the surface of the da...

Abstract

The invention discloses a method for repairing damage to a broken rubber conveying belt and a heating device thereof and belongs to the technical field of conveying belt repairing. In order to solve technical problems, the invention provides the method for repairing the broken rubber conveying belt and the heating device thereof, which are not limited by the environment temperature, only need lowtemperature heating and are convenient to operate. The invention adopts a technical scheme that the method for repairing the broken rubber conveying belt comprises the following steps of: polishing, conveying belt surface chemical treatment, adhesive coating, heating to activate adhesiveness, bonding, rolling and hammering. In the heating device for performing the method for repairing the broken rubber conveying belt, both a reflecting plate and a shell are n-shaped; the reflecting plate is positioned in the shell; a heating body is arranged at the top in the reflecting plate; two aluminium angle steels are symmetrically arranged below the shell and the reflecting plate; a protective net is arranged below the aluminium angle steels; one end of the side surface of the shell is a control area; and a switch is arranged in the control area. The method and the device can be popularized and applied to the repairing the broken conveying belt.

Description

technical field [0001] The invention relates to a method for repairing damaged rubber conveyor belts, belonging to the technical field of conveyor belt repairs. Background technique [0002] Conveyor belt damage is an unavoidable problem for conveyor belt users, and it is also a problem that affects the safe operation of the conveyor belt. For a long time, people have been exploring more effective maintenance solutions. At present, there are three main methods to solve such problems at home and abroad: [0003] The first is: high temperature thermal vulcanization repair. This process adopts the principle of rubber vulcanization, heating the conveyor belt to 145-155 degrees Celsius, so that the matrix rubber of the damaged part and the filled new rubber are fused together under a certain pressure to complete the repair. This method can basically restore the original performance of the damaged part, but the equipment used is heavy, the operation time is long, the speed is slo...
