Air Spinning Device Dual Separation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air spinning devices face challenges in achieving a compact configuration while allowing the second block to be moved away from the first block, leading to increased space requirements and potential contact issues with precision components, which complicates maintenance and visualization.
Innovation Solution
The air spinning device employs a dual separation mechanism where the second block can perform a linear separation operation followed by an arc motion separation operation, allowing for reduced space requirements and simplified power transmission, with integrated modular design for easy maintenance.

Engineering Contradiction Analysis
1Ease of operation
If the second block is linearly moved away from the first block along the fiber traveling direction, then the blocks can be separated to allow visual inspection, but a large amount of sliding space is required around the air spinning device
Solution Approach 1:
The patent transitions from single-dimensional linear sliding to two-dimensional compound motion. The second block performs linear sliding along the fiber traveling direction combined with swinging motion around a swinging shaft, enabling separation in multiple directions. This dimensional change allows the block to achieve sufficient separation distance without requiring excessive linear sliding space, as the swinging component contributes additional separation in a perpendicular dimension.
Solution Approach 2:
The separation motion is divided into two distinct segments: linear sliding motion and swinging motion. The linear guide rod handles the linear displacement while the swinging shaft handles the angular displacement. This segmentation allows each component to contribute to the overall separation without requiring the full separation distance from a single linear sliding action, thereby reducing the required sliding space.
2Ease of operation
If the arm length is extended to move the second block away from the first block in an angle close to a straight line, then the blocks can be separated, but the size of the air spinning machine becomes large
Solution Approach 1:
Instead of extending the arm length in a straight-line configuration, the patent utilizes a compact L-shaped arrangement where the linear guide rod and swinging shaft are positioned perpendicular to each other. This dimensional reconfiguration allows the second block to achieve effective separation through combined linear and angular motion without requiring a long extended arm, thereby maintaining a compact machine footprint.
3Ease of operation
If the second block is separated in an angle close to a straight line, then the blocks can be separated, but a space in view of the swinging of the second block needs to be provided around the air spinning device
Solution Approach 1:
The patent positions the swinging shaft at a strategic location where the swinging arc of the second block does not interfere with the linear sliding path of the first block. By optimizing the local arrangement of components and the swing radius, the design minimizes the required swinging space while ensuring sufficient separation between blocks for maintenance operations.

AI summary
An air spinning device (9) has a first block (60) and a second block (70). The first block (60) applies a swirling airflow to a fiber bundle (8). The second block (70) is arranged downstream of the first block (60) in a fiber traveling direction, and guides the fiber bundle further towards the downstream side. The second block (70) can perform a first separation operation in which the second block (70) is linearly moved away from the first block (60) along the fiber traveling direction, and a second separation operation which is performed after the first separation operation, the second separation operation being an operation in which an orientation of the second block (70) is changed while moving in a direction different from that in the first separation operation.
