Conveyor Belt Scraper Blade Mounting for Adaptive Contact and Reduced Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor belt cleaners face issues with uneven wear and ineffective cleaning due to fixed blade positions and inadequate tension adjustment, leading to premature belt wear and reduced cleaning efficiency.
Innovation Solution
A conveyor belt cleaning apparatus with a plurality of cleaning assemblies, each comprising a base member and a blade mounting assembly that allows rotational movement relative to the base member, ensuring consistent alignment and tension of scraper blades with the belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tensioners are used to apply force to the rail evenly, then the cleaning blades can maintain contact with the conveyor belt, but portions of the conveyor belt may be subjected to greater force than required, causing premature wear of the conveyor belt
Solution Approach 1:
The rail is divided into multiple independently adjustable sections, each capable of applying force locally rather than uniformly across the entire rail. This segmentation allows each section to be adjusted according to the specific wear conditions and material distribution at that location, preventing excessive force application to any single area of the conveyor belt.
Solution Approach 2:
The cleaning system implements local quality by allowing different sections of the rail to have different force application characteristics. Each section can be independently adjusted to match the local conditions of the conveyor belt, such as varying wear patterns and material accumulation, thereby applying the minimum necessary force locally rather than uniform force globally.
2Device complexity
If the cleaning blades are fixed in position relative to the direction of travel, then the structure is simple, but as the conveyor belt wears, more force must be applied to the rail to make the blades contact the conveyor belt
Solution Approach 1:
The cleaning system transitions from a static fixed blade position to a dynamic adjustable position system. Each rail section can be independently adjusted along the direction of travel to compensate for belt wear, maintaining optimal blade contact without requiring excessive force. This dynamic adjustment capability allows the system to adapt to changing belt conditions over time.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the contact force and position of each cleaning blade. This feedback enables automatic or manual adjustment of blade positions to maintain optimal contact pressure, preventing the need to continuously increase force as the belt wears. The feedback loop ensures blades remain effectively positioned despite belt degradation.
3Adaptability or versatility
If resilient cushions and flexible blades are used to allow deflection, then individual tips can deflect while maintaining contact, but the alignment, tension, or angle may not be ideal, reducing cleaning effectiveness
Solution Approach 1:
The system combines dynamic deflection capability with active adjustment mechanisms. While resilient cushions and flexible blades provide passive adaptation to belt irregularities, the independently adjustable rail sections provide active control to maintain optimal alignment, tension, and angle. This dual approach ensures both adaptability and cleaning effectiveness are achieved simultaneously.

AI summary
A blade mounting assembly for a conveyor belt cleaning assembly comprises a blade mount member for mounting a scraper blade; a connection portion; a resilient member disposed between the blade mount member and the connection portion; and a single adjustment member to couple the blade mounting assembly to a base member of the cleaning assembly and enable rotational movement of the blade mounting assembly about the single adjustment member relative to the base member. The resilient member provides yielding support to the scraper blade, to conform the scraper blade to irregularities and movement in a conveyor belt.
