Winding Device Pushing Member for Polygonal Bead Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding devices fail to securely bond the winding initiating and terminating ends of a wire around bead rings with polygonal cross-sections, as the bonding cord cannot maintain contact with the sides between adjacent corners, leading to loose connections.
Innovation Solution
A winding device with a rotor that rotates past the inner and outer sides of the bead ring, equipped with a pushing member that elastically pushes the bonding cord against the bead ring, ensuring contact and secure bonding even with polygonal cross-sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only a guide roller is used to guide the bonding cord during rotor rotation, then the device structure remains simple, but the bonding cord cannot maintain contact with the bead ring when the cross-sectional shape is polygonal, resulting in loose bonding
Solution Approach 1:
A pushing member is introduced as an intermediary component between the bonding cord and the bead ring. This pushing member actively pushes the bonding cord against the bead ring surface, ensuring continuous contact even when the bead ring has a polygonal cross-section. The guide roller serves as a mediator to guide the bonding cord's path, while the pushing member ensures firm contact, together resolving the issue of bonding cord separation without requiring complex structural modifications to the entire device.
Solution Approach 2:
The invention changes the operational parameters of the bonding cord guidance system by introducing a dynamic pushing force. Instead of relying solely on passive guidance, the pushing member applies variable force to maintain bonding cord contact with the bead ring. This parameter change (from passive to active guidance) ensures reliable bonding while keeping the overall device structure relatively simple.
2Manufacturing precision
If the bonding cord is allowed to curve without active pushing, then the device operation is simple, but the bonding cord separates from the bead ring sides between corners in polygonal cross-sections, preventing tight bonding
Solution Approach 1:
The pushing member is designed to automatically adjust and maintain bonding cord contact with the bead ring during the winding process. As the rotor rotates and the bonding cord is fed, the pushing member continuously pushes the cord against the bead ring surface, ensuring self-adjusting contact without requiring external intervention or complex control mechanisms. This self-service approach maintains high bonding precision while keeping the operation simple.
3Reliability
If a pushing member is added to elastically push the bonding cord against the bead ring, then the bonding cord maintains contact with polygonal bead rings for tight bonding, but the device structure becomes more complex
Solution Approach 1:
The bonding cord guidance function is segmented into two distinct components: the guide roller that directs the bonding cord's path and the pushing member that ensures contact with the bead ring. This segmentation allows each component to perform its specific function efficiently - the guide roller handles cord direction while the pushing member handles contact maintenance - resulting in a modular structure that is easier to manufacture and maintain despite the added functionality.
