How to join the conveyor belt

Abstract

Provided is a method that is for joining a conveyor belt having as a core layer a steel cord and that can increase the quality of the join and reduce the joining work time for the ends in the lengthwise direction of the belt. The core layer (1a) is formed in a manner so as to be exposed ahead of time at the ends (1A) in the lengthwise direction of the belt main body (1), the top of the core layer (1a) is covered by a peeling member (5), and a cover rubber (3a, 3b) is laminated to the top of the peeling member (5), in which state the belt main body (1) is vulcanized / molded; the peeling member (5) is peeled, eliminating the cover rubber (3a, 3b) laminated onto the peeling member (5) and exposing the core layer (1a); the steel cord (1b) of the core layer (1a) to which to join to is inserted into the steel cord (1b) that is of the exposed core layer (1a) and of which alternate strands in the belt width direction have been severed to a predetermined length; and after laminating a cushion rubber (2) and a cover rubber (3a, 3b), the result is vulcanized, thus joining the core layers (1a) to each other.

Description

technical field [0001] The present invention relates to a method of joining a conveyor belt having a core layer formed by arranging a plurality of steel cords side by side. More specifically, the present invention relates to a method capable of shortening the joining operation time and improving the quality of the joint at the ends of the conveyor belt in the longitudinal direction. Improved conveyor belt splicing method. Background technique [0002] A conveyor belt having a core layer formed of steel cords is stretched between driving rollers and driven rollers provided at the front and rear of the belt conveyor. And, it is supported by a plurality of guide rollers arranged between the driving roller and the driven roller. After a certain period of use and / or in the case of damage during use, replace the entire conveyor belt and / or cut off the damaged portion and join a new conveyor belt to the longitudinal end of the belt body (for example, Refer to Patent Documents 1 a...

AI Technical Summary

Problems solved by technology

At the site where the conveyor belt is used, there are restrictions on the working space and / or processing equipment, so there is a problem that cutting out the steel cord takes a lot of time.

[0010] In addition, the thicker the covering rubber, the more time is required to cut out the steel cord.

Therefore, the quality of the joint portion of the conveyor belt is adversely affected due to contamination of the joint portion by dust and / or water during the operation, resulting in a reduction in the joint strength.
