Circular Comb Adjustment Mechanism for Combing Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular combs for combing machines lack precise and continuous adjustment capabilities for the distance between the lower nipper plate and the enveloping circle, requiring step-wise adjustments and often necessitating removal from the machine for spacer element changes, which can lead to tension issues and limited precision.
Innovation Solution
A circular comb design featuring a clothing carrier and circular comb carrier attached to a shaft via connecting screws, with an insert rail and adjustment devices between the carrier and shaft, allowing for precise adjustment of the distance without altering the comb's shape or damaging the shaft, enabling continuous and accurate setting of the nipper plate's position relative to the enveloping circle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If arc-shaped spacer elements are used to adjust the circumradius of the comb set, then adjustment capability is provided, but the outer radius of the spacer element changes while the inner radius remains constant, leading to stresses between the beam and spacer element
Solution Approach 1:
The patent applies parameter changes by using interchangeable spacers with different thicknesses to precisely adjust the distance between the lower clamping plate and the outer circle of the round comb's combing element. Each spacer has specific dimensional parameters that allow precise positioning while maintaining constant radii, thereby avoiding stress concentration issues associated with arc-shaped spacers.
2Measurement precision
If interchangeable spacers are inserted between the base body and support element to precisely adjust the circumcircle radius, then adjustment precision is improved, but the round comb must be removed from the combing device to readjust and replace spacers
Solution Approach 1:
The patent segments the adjustment mechanism into modular components: the round comb support, the insert rail, and interchangeable spacers. This segmentation allows the spacers to be independently replaced without removing the entire round comb from the combing device, significantly reducing adjustment time while maintaining precision.
Solution Approach 2:
The insert rail acts as an intermediary element between the round comb support and the round comb shaft. It provides a standardized interface that allows spacers to be quickly exchanged without disturbing the main combing assembly, enabling rapid adjustments while preserving measurement precision.
3Adaptability or versatility
If wedge elements are inserted between the round comb support and round comb shaft for height adjustment, then continuous adjustment is enabled, but the wedge elements must be guided in the axial direction to avoid tilting and damage
Solution Approach 1:
The patent uses simple, replaceable spacers instead of complex wedge elements that require guidance mechanisms. The spacers are straightforward cylindrical or rectangular elements that can be easily inserted and removed without requiring complex guidance structures, thereby reducing device complexity while still enabling precise adjustment.
