Belt Conveyor Roller Attachment Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-sized printers with belt conveyors face challenges in efficiently attaching and detaching rollers for belt replacement and cleaning, due to the complexity and accessibility of the roller system.
Innovation Solution
A device with a guide and roller holder is introduced, allowing for the attachment and detachment of rollers from the front side of the belt conveyor. The guide extends along the longitudinal direction of the roller and includes a guide groove, while the roller holder has engagement portions for the front and rear plates and a guided portion that slides along the guide groove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rollers are attached and detached from the rear side of the belt conveyor, then the roller system is stable and secure, but the maintenance complexity increases and operational efficiency decreases due to difficult accessibility
Solution Approach 1:
The patent inverts the conventional attachment approach by enabling roller attachment and detachment from the front side of the belt conveyor instead of the rear side. The guide structure is configured with a guide groove that receives the guided portion of the roller holder, allowing front-side access for maintenance operations while maintaining secure engagement through the engagement portions with the front and rear plates.
2Ease of operation
If a guide structure is added to facilitate roller attachment and detachment, then ease of operation improves, but device complexity increases
Solution Approach 1:
The guide structure is segmented into distinct functional components: a guide body with a guide groove, a roller holder with a guided portion, and engagement portions. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and maintenance of the guide system.
Solution Approach 2:
The guide structure acts as an intermediary mechanism between the roller holder and the belt conveyor frame. The guide groove receives the guided portion of the roller holder, providing a mediating interface that facilitates smooth attachment and detachment motions while maintaining precise alignment and engagement.
3Stability of the object's composition
If engagement portions are provided for both front plate and rear plate, then roller stability improves, but device complexity increases
Solution Approach 1:
The engagement portions are merged with the roller holder structure, integrating the engagement functionality directly into the roller holding mechanism. This combination eliminates the need for separate engagement devices while providing secure attachment to both the front plate and rear plate, thereby maintaining roller stability without proportionally increasing device complexity.

AI summary
A device attaches and detaches at least one of rollers in a belt conveyor in which an endless belt is wound around the rollers between a front plate and a rear plate of the belt conveyor. The device includes a guide and a roller holder. The guide has a base end and extends along a longitudinal direction of the detachable roller and includes a guide groove. The roller holder holds the detachable roller and includes an engagement portion, another engagement portion, and a guided portion. The engagement portion detachably engages with the front plate. The other engagement portion detachably engages with the rear plate. The guided portion slides along the guide groove toward the rear side or the front side of the device to engage or disengage the engagement portion with or from the front plate and engage or disengage the other engagement portion with or from the rear plate.
