Angled Tooth Scraper Blade Mounting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor belt cleaners face issues with scraper blade replacement, material buildup, and reduced cleaning efficiency due to blade seizure, large footprint, and material accumulation on rear surfaces.
Innovation Solution
A scraper blade mounting assembly with angled teeth on the support cartridge and a cam lock mechanism allows for easy removal and replacement of scraper blades without sliding them along the cartridge length, reducing material buildup by eliminating horizontal surfaces on the blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If scraper blades are designed to slide along the length of the cartridge for removal, then the blades can be replaced, but the blades seize/bind during removal due to material buildup in the horizontal track
Solution Approach 1:
The engaging means uses angled teeth (inclined planes) instead of horizontal sliding surfaces. The blades engage and disengage by sliding along the angled teeth rather than along a horizontal track, which prevents material buildup that causes seizing. The curved/angled geometry eliminates the flat horizontal surfaces where fines accumulate.
Solution Approach 2:
The invention extracts the problematic horizontal sliding track from the system and replaces it with angled teeth engagement. This removes the source of material buildup and blade seizure while maintaining the blade replacement functionality.
2Ease of manufacture
If scraper blades have horizontal surfaces for mounting, then the blades can be easily installed, but material builds up on the rear surfaces of blades where horizontal surfaces are present
Solution Approach 1:
The blade rear surfaces are designed without horizontal surfaces. Instead, the engaging means uses angled teeth that create inclined surfaces, preventing material from accumulating on the blade rear surfaces. The angled geometry allows material to slide off rather than build up.
3Ease of operation
If the conveyor is shut down for scraper blade replacement, then safety is improved, but productivity is reduced due to downtime
Solution Approach 1:
The locking means (cam lock) is designed to quickly secure blades in place before operation and allow for rapid release during maintenance. This preliminary preparation of the locking mechanism enables fast blade changes that minimize conveyor shutdown time while maintaining safety.
Solution Approach 2:
The mounting assembly is segmented into removable blade components and a stationary cartridge with locking means. This segmentation allows individual blades to be quickly replaced without affecting the entire cleaning system, enabling maintenance during shorter shutdown periods.
4Adaptability or versatility
If the engaging means allows sliding movement along the cartridge length, then blade installation is flexible, but the footprint of the device increases due to stiffeners
Solution Approach 1:
The angled teeth provide the necessary engagement and disengagement movement in a compact configuration. The inclined geometry allows blade installation and removal without requiring additional stiffeners or extending the cartridge length, maintaining a compact footprint while preserving installation flexibility.
