Strip Cutting Support Pivoting for Precise Conveyor Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for strip materials, such as steel or textile cords, face challenges in achieving high precision when depositing cut sections onto a conveyor belt due to a relatively large distance between the lower blade and the removal belt, leading to limited accuracy for subsequent processing steps.
Innovation Solution
A cutting device with a two-part support component, where the first component section is pivotable about a first axis between a horizontal and an angled position, and the second component section is pivotable about a second axis, allowing independent pivoting to minimize the fall height of cut material sections by adjusting the position of the upper run of the conveyor belt relative to the cutting edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single support component is used to hold the conveyor belt, then the structure is simple, but the ability to independently adjust different sections of the belt is limited, reducing precision in material placement
Solution Approach 1:
The support component is divided into a first component section and a second component section, which can be independently pivoted about different axes. This segmentation allows each section to be adjusted independently to optimize the belt position relative to the cutting edge, thereby improving material placement precision while maintaining manageable structural complexity through modular design
2Manufacturing precision
If the upper run of the conveyor belt is positioned closer to the cutting edge to reduce fall height, then material placement accuracy improves, but the risk of contact between the belt and upper blade increases
Solution Approach 1:
The support component is designed to be dynamically adjustable, allowing the upper run of the conveyor belt to be positioned at different angles and heights. During operation, the belt can be raised to a first angle to reduce fall height and improve placement accuracy, then lowered to a second angle to prevent contact with the upper blade, thus dynamically resolving the contradiction between precision and safety
3Adaptability or versatility
If the support component is positioned at a fixed angle to the horizontal, then the structure is simple, but the ability to adapt to different cutting positions is limited
Solution Approach 1:
The support component incorporates pivoting mechanisms that allow it to assume different angular positions relative to the horizontal. The first component section can be pivoted about a first axis, and the second component section can be pivoted about a second axis, enabling the system to adapt to various cutting positions and configurations while maintaining a relatively simple mechanical structure
Solution Approach 2:
The adjustable support component serves multiple functions: it can position the conveyor belt at optimal angles for different cutting operations, adjust the distance between the belt and cutting edge, and prevent belt-blade contact. This multi-functionality increases adaptability without proportionally increasing device complexity
