Eccentric Support Roller for High-Cleat Conveyor Belt Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belts with cleats face difficulties when using stationary bottom belt rollers, as they can entangle elongated foreign materials, leading to maintenance challenges, and existing solutions complicate the use of cleated belts.
Innovation Solution
A support roller design with an eccentrically mounted carrier and shell, featuring a carrier with an axle receptacle that is rotationally fixed, allowing for conveyor belts with high cleats to be guided on small-diameter rollers, and includes clamping means for easy installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stationary bottom belt rollers are used to prevent coiling of elongated foreign materials, then maintenance costs are reduced, but the use of conveyor belts with cleats becomes more difficult
Solution Approach 1:
The support roller is divided into a carrier (stationary part with axle receptacle) and a shell (rotating part that contacts the belt). This segmentation allows the carrier to remain rotationally fixed to prevent material coiling, while the shell can rotate freely to accommodate cleated conveyor belts, thus resolving the contradiction between preventing coiling and easing belt guidance
Solution Approach 2:
Instead of making the entire support roller stationary as in prior art, this invention inverts the approach by making only the carrier stationary while the shell rotates. This reversal allows the rotating shell to guide cleated belts easily while the stationary carrier prevents material coiling, solving both problems simultaneously
2Productivity
If conveyor belts with high cleats are used, then material transport capability is improved, but the required roller diameter increases
Solution Approach 1:
The invention introduces eccentric mounting of the axle receptacle, creating an offset between the rotation center and the carrier center. This dimensional change allows the shell to rotate with a larger effective diameter for guiding high-cleat belts, while the carrier itself can have a smaller mounting diameter, thus enabling high productivity with reduced roller size
3Ease of manufacture
If the support roller is designed in multiple parts, then installation and maintenance are simplified, but device complexity increases
Solution Approach 1:
The support caps combine multiple functions into single components: they serve as structural elements, clamping means for securing the shell to the carrier, and maintenance facilitators through their removable design. This merging reduces the need for separate clamping devices and simplifies installation/maintenance while keeping the overall part count manageable
