Solution Overview

Problem

The separation of steel wire rope cores from the rubber layer in conveyor belts is labor-intensive and time-consuming, especially at conveyor belt joints, due to the need for sequential cutting of the rubber layer around each core.

Innovation Solution

A method involving flat and forming cutters is employed to cut the rubber layer along specific directions relative to the conveyor belt, with the flat cutter cutting the rubber layer on either side of the cores in the thickness direction and the forming cutter cutting the rubber layer between cores in the width direction, using a combination of conveyor movement and cutter arrangement to optimize efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If sequential cutting of rubber layer around each steel wire rope core is performed, then complete separation of cores from rubber layer is achieved, but labor intensity increases and time consumption increases

Engineering Contradiction:

Improveseparation completenessVSAvoidseparation efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The cutting process is segmented into two distinct directions: flat cutters perform cutting in the thickness direction of the conveyor belt, while forming cutters perform cutting in the width direction. This segmentation allows simultaneous multi-point cutting along the entire length of the conveyor belt, transforming the sequential single-point cutting process into parallel multi-point cutting, thereby dramatically improving separation efficiency while maintaining complete separation of cores from the rubber layer

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces cutting in two dimensional directions (thickness direction by flat cutters and width direction by forming cutters) instead of single-direction sequential cutting. This dimensional change enables the cutting tool to engage multiple cores simultaneously along the conveyor belt length, converting a time-consuming sequential process into an efficient parallel process that maintains separation completeness

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If sequential cutting of rubber layer around each steel wire rope core is performed, then complete separation of cores from rubber layer is achieved, but time consumption increases

Engineering Contradiction:

Improveseparation completenessVSAvoidseparation time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The cutting operation is divided into two segmented processes: flat cutting in the thickness direction and forming cutting in the width direction. Each cutter type targets specific rubber layers simultaneously along the entire conveyor belt length, reducing the total time required while ensuring complete separation of all cores from the rubber layer

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flat cutters and forming cutters operate continuously along the entire length of the conveyor belt joint, maintaining constant cutting action across all cores simultaneously. This continuous multi-point cutting eliminates idle time between sequential operations, dramatically reducing separation time while ensuring complete separation

Inventive Principle:

Principle #20Continuity of useful action

3Manufacturing precision

If manual sequential separation of steel wire rope cores is performed, then precise separation is achieved, but labor intensity increases

Engineering Contradiction:

Improveseparation precisionVSAvoidoperational ease

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The separation operation is segmented into automated flat cutting and forming cutting processes, eliminating manual sequential handling. The segmented cutter arrangement (flat cutters for thickness direction, forming cutters for width direction) automatically performs precise separation across all cores simultaneously, maintaining separation precision while dramatically improving operational ease by eliminating labor-intensive manual operations

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Manual mechanical separation operations are replaced with automated cutting mechanisms. The flat cutters and forming cutters, driven by the conveyor belt movement, automatically perform the separation function that previously required manual sequential handling, maintaining precision while significantly improving ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
