Shot Blasting Conveyor Roller Support Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal-belt shot blasting machines experience significant wear and tear, leading to unwanted play between the lateral chain links and pins, causing jamming and potential breakdowns, which requires frequent manual maintenance and increases operating costs.
Innovation Solution
The integration of support devices with rotating rollers positioned below the lateral chains of the conveyor belt, particularly at the concave portion, to reduce mechanical wear and prevent play formation between links and pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a metal conveyor belt is used in a shot blasting machine, then the machine can effectively treat heat-treated pieces and large heavy pieces, but the abrasive material causes significant wear to the conveyor belt and lateral chains, leading to play formation and jamming
Solution Approach 1:
Rollers are introduced as intermediary elements between the abrasive environment and the lateral chains. These rollers are positioned to contact the pins and links of the lateral chains, acting as a protective mediator that prevents direct abrasive damage to the chain components while allowing the conveyor to maintain its load-bearing and transporting functions
Solution Approach 2:
The rollers are installed in advance to prevent wear damage before it occurs. By positioning the rollers to contact the lateral chain components beforehand, the system creates a protective barrier that cushions against the abrasive material, preventing play formation between pins and links before it can develop into jamming or breakdown
2Productivity
If the conveyor belt operates continuously without support devices, then productivity is maintained, but wear leads to play between pins and links causing jamming and system breakdown
Solution Approach 1:
Rollers serve as intermediary protective elements that enable continuous operation without compromising reliability. These rollers are strategically positioned to contact the lateral chains at critical wear points, mediating between the abrasive environment and the chain components, thereby allowing uninterrupted conveyor operation while preventing wear-induced failures
3Reliability
If manual adjustment of lateral chain tension is performed frequently, then play between links and pins can be reduced, but maintenance time and operating costs increase
Solution Approach 1:
The rollers provide automatic, continuous protection against wear without requiring manual intervention. Once installed, the rollers self-adjust to the lateral chain position and continuously prevent play formation through their rotational contact with the pins and links, eliminating the need for frequent manual tension adjustments and reducing maintenance time
Solution Approach 2:
The rollers act as self-adjusting intermediary elements that automatically compensate for wear tendencies. By maintaining constant contact with the lateral chain components, the rollers provide ongoing protection against play formation without requiring external adjustment mechanisms or frequent maintenance interventions
