Brush Stuffing Machine Rotary Pivot Guideway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush stuffing machines require complex and space-consuming guideways for the stuffing tool, which limits space availability and mechanical capacity, especially at high operational rates.
Innovation Solution
The stuffing tool is pivotally mounted to move on a circular arc between positions, allowing a rotary movement instead of linear, enabling a simpler and more space-efficient design with reduced mechanical stress, using a swivel bearing instead of a sliding bearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a translational guideway is used for the stuffing tool, then the stuffing tool can move linearly between positions, but the guideway becomes complex and space-consuming
Solution Approach 1:
The patent replaces the linear translational guideway with a rotary movement mechanism where the stuffing tool moves along a circular arc trajectory. The bearing unit is positioned at a distance from the brush body holder, creating a rotational pivot point that simplifies the guideway structure while maintaining the necessary movement capability between bundle take-over and stuffing positions.
2Ease of operation
If a translational guideway is used for the stuffing tool, then the stuffing tool can move linearly, but the space available in the region is reduced
Solution Approach 1:
The patent transitions from one-dimensional linear movement to two-dimensional rotary movement. By positioning the bearing unit at a distance and allowing the stuffing tool to swing along a circular arc, the system utilizes radial and angular dimensions rather than solely linear displacement, thereby reducing the linear space requirement in front of the brush body holder.
3Productivity
If high clock rates are used with a translational guideway, then productivity increases, but the mechanical capacity limits are exceeded
Solution Approach 1:
The patent replaces the sliding bearing mechanism with a rotary pivot mechanism. The swivel bearing allows for smoother, higher-speed operation with reduced friction and mechanical stress compared to translational sliding bearings. This substitution enables higher operational rates while maintaining mechanical reliability, as the rotary movement naturally reduces relative velocity between stationary and moving parts.
4Ease of operation
If a sliding bearing is used for the stuffing tool, then linear movement is achieved, but mechanical loads increase
Solution Approach 1:
The patent employs a rotary pivot mechanism where the stuffing tool swings along a circular arc rather than moving linearly. This curved path movement reduces the relative velocity between the moving stuffing tool and stationary components, thereby decreasing friction forces and mechanical loads on the bearing unit compared to high-speed linear sliding movement.
