Solution Overview
Problem
Traditional belt conveyor tensioning devices are bulky, complex, difficult to access, lack precision, and not suitable for all production sectors due to dust infiltration issues, requiring modifications and special tools, which increases costs.
Innovation Solution
A compact, integrated tensioning device attached to the conveyor frame with a novel mechanism using box-type bodies and threaded screws to adjust the centre distance between the motor and reversing rollers, allowing easy access and high precision tensioning without bulkiness, suitable for use in clean environments like white rooms or food sectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional accessory tensioning devices are used, then the conveyor belt can be tensioned, but the devices become bulky and constructionally complex
Solution Approach 1:
The tensioning device is integrated directly into the conveyor frame structure, merging the tensioning function with the supporting structure. The box-type bodies are attached to the frame shoulders and house the tensioning mechanism, eliminating the need for separate accessory devices and reducing overall structural complexity.
Solution Approach 2:
The tensioning device is divided into modular components: box-type bodies attached to frame shoulders, threaded screws for adjustment, and end elements for roller support. This segmentation allows for easier manufacturing, assembly, and maintenance while reducing the complexity of any single component.
2Reliability
If traditional tensioning devices are used, then tensioning is achieved, but they are difficult to access and require removal of components or special tools
Solution Approach 1:
The box-type bodies are pre-attached to the frame shoulders with openings that provide direct access to the threaded screws. This preliminary positioning ensures that the tensioning mechanism is accessible from the outside without requiring disassembly of protective covers or specialized tools, enabling easy maintenance and adjustment.
3Reliability
If traditional tensioning devices are used, then belt tensioning is achieved, but precision is insufficient
Solution Approach 1:
The mechanical adjustment system uses precision-threaded screws with defined pitch values (e.g., 1.5 mm or 2 mm) that convert rotational motion into precise linear displacement. This allows for accurate control of the center distance between rollers and precise positioning of the belt tensioning point, achieving high tensioning precision through standardized threaded fasteners.
4Reliability
If traditional tensioning devices are used, then tensioning is achieved, but they cannot be used in clean environments without modifications due to dust infiltration
Solution Approach 1:
The box-type bodies serve as protective enclosures that can be sealed to prevent dust infiltration. The design allows for integration of seals or covers on the box-type bodies, creating a protected environment for the threaded screws and tensioning mechanism, making the device suitable for clean room or food sector applications without requiring additional modifications.
