Upper Apron Holder Guide Groove Outside Track Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing top apron holders for spinning machines experience significant variation in the deflection edge movement due to the limited arrangement of guide pins and channels within the track width, leading to tilting issues when the operating state changes, affecting the precision of the spinning process.
Innovation Solution
The arrangement of guide elements, such as guide grooves and rails, is extended outside the track width of the upper apron, allowing for longer guide lengths and reducing the up and down movement of the deflection edge, with optional interruptions to ensure continuous engagement and prevent tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the guide pins and channels are arranged within the track width of the upper apron, then the structure is compact and simple, but the deflection edge movement becomes excessive and causes tilting issues
Solution Approach 1:
The guide elements are moved from a two-dimensional arrangement within the track width to a three-dimensional arrangement that extends outside the track width. This spatial extension allows the guide elements to be longer and provide better constraint on the deflection edge, reducing excessive movement while maintaining structural simplicity.
2Manufacturing precision
If the guide elements are extended outside the track width, then the deflection edge movement is reduced to functional play level, but the device complexity increases
Solution Approach 1:
The guide system is segmented into multiple guide elements distributed both within and outside the track width. This segmentation allows each guide element to perform its specific guidance function independently, achieving precise control of the deflection edge while keeping the overall structure modular and manageable.
3Manufacturing precision
If the guide elements are made longer to reduce deflection movement, then the position stability improves, but the device complexity and space requirements increase
Solution Approach 1:
Instead of increasing guide element length in one dimension within the track width, the guide elements are extended in multiple dimensions by arranging them outside the track width as well. This multi-dimensional arrangement achieves the required guidance precision without excessive lengthening of individual elements.

AI summary
The holder (1) has an upper apron stretched by elastic force, and a strappy guide (3) turned on a bending edge (16) and clamped on an intermediate section (2). A guidance plate (12) is arranged on the intermediate section as a guidance groove (11) that is carried out continuously, where the plate is arranged on the strappy guide on an outer side of a track width of the upper apron, and guides a pair of guide parts of the strappy guide. A short side of the guidance groove is arranged on an outer edge of the intermediate section.
