Circular Comb Carrier Spring Ribs Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular comb carriers for combing machines face challenges in adjusting the distance between the lower nipper plate and the enveloping circle of the combing assembly, with existing solutions either being complex to process, leading to tension issues or requiring removal of the circular comb for adjustments, and lacking precise incremental adjustment capabilities.
Innovation Solution
A carrier design featuring a central profile with a clothing support surface and spring ribs that deflect to support the circular comb shaft, allowing for continuous adjustment of the distance between the nipper plate and the enveloping circle without removing the circular comb, using spring ribs with specific angles and supports to ensure stable attachment and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an arc-shaped spacer element is used to adjust the circumradius of the comb set, then the distance between the lower jaw plate and the comb set can be adjusted, but the outer radius of the spacer changes while the inner radius remains constant, leading to stresses between the beam and spacer
Solution Approach 1:
The patent changes the geometric parameters of the spacer element by providing multiple spacers with different thicknesses (e.g., 2mm, 3mm, 4mm) to achieve different circumradii adjustments. Each spacer is designed with matching inner and outer radii that correspond to specific comb set configurations, eliminating the stress issue caused by radius mismatch while maintaining adjustment precision
Solution Approach 2:
The patent enables dynamic adjustment of the comb set circumradius by allowing the operator to select and install different thickness spacers based on the required adjustment. This makes the system adaptable to different combing requirements without being fixed to a single radius configuration
2Manufacturing precision
If interchangeable spacers are used to precisely adjust the radius of the comb assembly's circumcircle, 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 provides a set of spacers with different thicknesses that are pre-manufactured with precise dimensions. These spacers can be stored and quickly exchanged without requiring removal of the entire round comb assembly, as the spacers are accessible through the carrier structure. This preliminary preparation of multiple spacer options enables rapid adjustment while maintaining precision
3Productivity
If the number of comb cycles per minute is increased to increase productivity, then productivity is improved, but the relatively large mass of the rotary comb needs to be accelerated or decelerated more frequently, placing high demands on the drive system and support structure
Solution Approach 1:
The patent segments the support structure into multiple components: a carrier with spring ribs, a comb assembly, and a hub. The spring ribs act as independent elastic elements that can deflect to absorb and release energy during acceleration and deceleration phases. This segmentation allows the support structure to better handle dynamic forces without requiring a complete redesign of the entire system
Solution Approach 2:
The spring ribs are pre-loaded with elastic energy that can be released to cushion the acceleration and deceleration forces. When the comb assembly needs to be accelerated or decelerated, the spring ribs deflect accordingly, absorbing the shock and reducing the peak forces transmitted to the drive system and support structure. This beforehand cushioning effect protects the system from the high forces generated by frequent speed changes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise and continuous adjustment of the distance between the nipper plate and the enveloping circle, reducing tension and simplifying the adjustment process, while maintaining stable attachment of the circular comb, even under high acceleration forces, without the need to remove the comb from the combing device.
Implementation Method 1
At least one pair of spring ribs (52, 57) is arranged on the central profile (51) to support the carrier (49) on a round comb shaft (8) or a support body (53). The spring ribs (52, 57) each have a support (33) at an end facing away from the central profile (51), which, when the support surface (50) rests on a surface of the round comb shaft (8) or on a surface of the support body (53), are deflected to a maximum degree.
