Self-Adjusting Conveyor Belt Scraper for Wear Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor belt cleaners require manual adjustment of the belt scraper, leading to increased labor costs and potential neglect of necessary adjustments, resulting in residual material on the conveyor belt that can damage system components.
Innovation Solution
An automatic belt-scraper-adjusting device that includes a shell seat, connecting component, and force-applying assembly, which automatically adjusts the belt scraper by rotating the pivot shaft to maintain contact with the conveyor belt, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual checking and adjustment of the belt scraper is implemented, then the belt scraper can be adjusted when needed, but labor costs increase and manual checking may be neglected
Solution Approach 1:
The belt scraper adjusting device automatically adjusts the belt scraper's position and contact force with the conveyor belt without requiring manual intervention. The device uses a spring-loaded mechanism that self-regulates the scraper's pressure and position, eliminating the need for periodic manual checking and adjustment while maintaining reliable cleaning performance
Solution Approach 2:
The adjusting device incorporates a feedback mechanism where the spring force continuously monitors and adjusts the belt scraper's contact pressure. When the scraper wears down or the belt position changes, the spring automatically compensates by adjusting the scraper's position to maintain optimal contact, creating a closed-loop control system that ensures consistent cleaning reliability
2Productivity
If the belt scraper is allowed to wear without adjustment, then labor costs are reduced, but the scraper gaps from the conveyor belt causing cleaning failure
Solution Approach 1:
The adjusting device transforms the static belt scraper into a dynamically adjustable component. The spring-loaded mechanism allows the scraper to automatically move closer to the conveyor belt as it wears, maintaining continuous contact and cleaning effectiveness throughout the scraper's service life without interrupting production for adjustments
Solution Approach 2:
The device pre-loads the belt scraper with spring force during installation, creating built-in compensation capacity for future wear. This preliminary action ensures that as the scraper gradually wears down over time, the stored spring energy automatically drives the adjustment mechanism to maintain contact, preventing cleaning failure before it occurs
3Reliability
If the belt scraper is adjusted frequently to maintain contact, then cleaning effectiveness is maintained, but maintenance time and operational interruptions increase
Solution Approach 1:
The adjusting device ensures continuous cleaning action by automatically compensating for scraper wear in real-time. The spring mechanism continuously applies force to maintain scraper-belt contact, eliminating periods where the scraper would otherwise gap from the belt and ensuring uninterrupted cleaning effectiveness throughout operation
Solution Approach 2:
The system performs its own adjustment function automatically without requiring operational shutdown or maintenance personnel intervention. The self-adjusting mechanism handles all scraper position corrections internally during normal operation, eliminating time loss associated with manual adjustment cycles and maintaining continuous productive operation

Function Achieved in This Case
The automatic adjustment ensures consistent cleaning of the conveyor belt, preventing residual material from damaging components and reducing labor and maintenance costs by eliminating the need for manual checks and adjustments.
Implementation Method 1
at least one force-applying assembly mounted inside the shell seat, connected to the connecting component, and configured to apply a steady adjusting force to the connecting component

AI summary
An automatic belt-scraper-adjusting device configured to connect a pivot shaft of a scraper set of a conveyor belt cleaner comprises a shell seat, a connecting component and at least one force-applying assembly. The connecting component connected to the pivot shaft is rotatably mounted at the shell seat and is rotated along a preparing direction. The force-applying assembly mounted inside the shell seat and connected to the connecting component applies a steady force on the connecting component. A belt scraper of the scraper set is connected to the pivot shaft and abuts a conveyor belt, so the connecting component cannot be rotated. During cleaning the conveyor belt, the belt scraper is gradually worn off, so the force-applying assembly can rotate the connecting component along a direction opposite to the preparing direction. Therefore, the belt scraper continues to abut the conveyor belt automatically, cutting down labor and maintenance costs.
