Winding Machine Brake Cam for Pivot Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding machines are cumbersome and time-consuming to operate due to the difficulty in adjusting the starting pivot angle of the traverse mechanism carrier, leading to inadequate gap settings between the pressure roller and the winding sleeve, resulting in defects and reduced quality of the wound bobbin.
Innovation Solution
A winding machine with a manually actuable braking device and a stop element contour with multiple subsections allows for easy adjustment of the starting pivot angle, enabling precise manipulation of the gap between the pressure roller and the winding sleeve, and automatic actuation of the motor for improved safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stop element is adjusted by manually rotating a screw to change the starting pivot angle, then the gap between the pressure roller and winding sleeve can be modified, but the adjustment process becomes time-consuming and operationally complex
Solution Approach 1:
The stop element is designed with a rotatable cam profile that provides different pivot angles in different rotational positions. This dynamic structure allows the operator to quickly select between pre-defined starting pivot angles by simply rotating the cam to different positions, rather than manually adjusting a screw mechanism. The cam's rotational movement dynamically changes the gap between the pressure roller and winding sleeve, enabling fast adaptation without complex adjustments.
2Manufacturing precision
If the traverse mechanism carrier is positioned close to the winding sleeve to reduce the gap, then the winding quality improves, but the risk of contact between the pressure roller and the empty winding sleeve increases
Solution Approach 1:
The cam profile is pre-configured with specific pivot angle positions that correspond to optimal gap settings for different winding stages. Before the winding process begins, the operator selects and sets the appropriate starting pivot angle using the cam mechanism. This preliminary action ensures that the traverse mechanism carrier is positioned at the correct distance from the winding sleeve, preventing contact between the pressure roller and the empty winding sleeve while maintaining optimal winding quality throughout the process.
3Ease of operation
If multiple switch mechanisms are provided for motor activation, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The cam mechanism serves multiple functions: it not only defines the starting pivot angle for the traverse mechanism carrier but also acts as a single switch mechanism for motor activation. When the operator rotates the cam to the correct position, this same rotational action simultaneously activates the motor through an integrated switch mechanism. This multi-functional design eliminates the need for separate start buttons or switches, reducing device complexity while maintaining ease of operation.
