Conveyor Sealing Flap Elastic Deformation Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk material conveyors with sealing flaps face challenges in assembly and dismantling, requiring lengthy cleaning operations and tool handling due to dust and corrosion, leading to wear and frequent flap replacements.
Innovation Solution
A conveyor system with a sealing flap fixation mechanism using an elastic deformation fitting means, where a female part on the flap surrounds a male part on the guide wall, allowing for quick replacement without cleaning, and a cover to prevent material infiltration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing flaps are fixed using screws and nuts or clamp jaws, then the sealing flap can be securely attached to the guide wall, but the assembly and dismantling operations become long and tedious, requiring tool handling and cleaning operations
Solution Approach 1:
The fixing means is divided into two fractions: one carried by the flap and the other by the conveyor structure. This segmentation allows the sealing flap to be quickly attached and detached without complex tool operations, resolving the contradiction between secure attachment and quick replacement.
Solution Approach 2:
Instead of using traditional screw or clamp mechanisms that require tools for assembly and disassembly, the invention inverts the approach by using a friction-based fitting means that allows tool-free installation. The elastic deformation mechanism enables the fixing means to securely hold the flap during operation but allows easy removal by simply pulling the flap away.
2Reliability
If traditional fixing means with screws are used, then the sealing flap can be attached to the guide wall, but dust accumulation on screw threads and corrosion make handling more delicate and require cleaning operations
Solution Approach 1:
The invention extracts the problematic screw threads and cleaning-prone surfaces from the fixing mechanism. By using a friction-based fitting means with elastic deformation, the design eliminates exposed screw threads where dust accumulates and corrosion occurs, making the fixing means much easier to handle during maintenance operations.
Solution Approach 2:
The fixing means is designed as a simple, durable friction-based mechanism that can be quickly replaced if needed, without requiring complex cleaning or maintenance of threaded components. This approach treats the fixing mechanism as a simple, replaceable component rather than a complex, maintenance-intensive system.
3Object-affected harmful factors
If the sealing flap is designed to cover the conveyor belt top, then it prevents material from passing beyond the side edges, but friction causes wear of the sealing flap requiring frequent replacement
Solution Approach 1:
The invention changes the attachment parameters of the sealing flap by using a friction-based fitting means with elastic deformation rather than rigid mechanical fastening. This allows the sealing flap to be easily replaced when worn, and the design can incorporate material selection and geometric optimization to reduce friction and wear during operation.
