Laminator Glue Jamming Prevention via Elastic Axle Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laminators often experience glue jamming due to size issues such as excessive thickness or non-uniformity, leading to unsmooth or incomplete lamination, making the process inconvenient.
Innovation Solution
The use of a first and second driving belt in collaboration with left-side and right-side elastic assemblies to ensure continuous rotation of the driving axles, preventing glue jamming by compressing the elastic assemblies when encountering large or irregularly shaped objects, thus maintaining smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only two rollers are used to drive the object, then the structure is simple, but glue jamming occurs when encountering excessive thickness or non-uniformity
Solution Approach 1:
The patent applies the dynamics principle by using elastic assemblies that can dynamically adjust their compression force based on the object's thickness and shape. The elastic assemblies deform and recover continuously, allowing the driving belts to maintain contact with objects of varying dimensions without requiring a complex adjustable mechanism, thus resolving the contradiction between structural simplicity and operational reliability.
Solution Approach 2:
The patent utilizes parameter changes by allowing the elastic assemblies to change their physical state (compression and deformation) in response to varying object dimensions. This enables the driving system to adapt to different object parameters (thickness, uniformity) automatically, preventing glue jamming while keeping the overall structure relatively simple.
2Reliability
If driving belts are used with elastic assemblies to prevent glue jamming, then lamination reliability improves, but device complexity increases
Solution Approach 1:
The patent merges the driving function and the adaptive adjustment function into a unified system where the elastic assemblies are integrated with the driving belts and axles. This combination allows the system to maintain reliable lamination while avoiding the need for separate complex adjustment mechanisms, thus minimizing the increase in device complexity.
Solution Approach 2:
The elastic assemblies perform self-service by automatically adjusting their compression force based on the object's dimensions without requiring external control or complex sensing systems. This self-regulating capability maintains high lamination reliability while keeping the device structure relatively simple.
3Adaptability or versatility
If the driving axles can compress elastic assemblies, then adaptability to different object sizes improves, but the structure becomes more complex
Solution Approach 1:
The patent employs flexible elastic assemblies that can deform and adapt to objects of various sizes and shapes. These elastic components act as flexible elements that automatically adjust to different object dimensions, providing high adaptability while maintaining a relatively simple structural implementation compared to rigid adjustable mechanisms.
