Rotor Spinning Self-Cleaning Structure and Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotor spinning devices require the machine to be stopped for cleaning, which disrupts production efficiency and can lead to uneven yarn quality due to impurities accumulating in the condensing groove.
Innovation Solution
A self-cleaning structure for rotor spinning devices that includes a cleaning rod with a guiding arc surface, a driving device to adjust its length, and a control system to detect and respond to residue levels, allowing for automatic cleaning without stopping the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotor is opened for cleaning using prior art devices, then the cleaning effect is achieved, but the spinning operation must be interrupted which reduces productivity
Solution Approach 1:
The rotor spinning device performs cleaning of its own condensing groove while continuing to operate, without requiring external intervention or shutdown. The cleaning rod is automatically extended into the groove to remove impurities during normal spinning operations
Solution Approach 2:
The cleaning rod is positioned and prepared in advance within the rotor structure, allowing it to be quickly deployed into the condensing groove when cleaning is needed, rather than requiring assembly or external positioning during maintenance
2Reliability
If the cleaning rod is constantly extended into the condensing groove, then continuous cleaning is achieved, but the cleaning rod will collide with the rotor inner wall causing wear
Solution Approach 1:
The cleaning rod is designed to be dynamically adjustable in position, extending only when cleaning is required and retracting when not needed. This dynamic positioning prevents continuous contact with the rotor inner wall, reducing wear while maintaining cleaning capability
Solution Approach 2:
The system uses a sensor to detect the presence of impurities in the condensing groove and provides feedback to the control device, which then activates the driving device to extend the cleaning rod only when cleaning is actually needed, avoiding unnecessary contact and wear
3Productivity
If impurities accumulate in the condensing groove, then production continues uninterrupted, but yarn quality deteriorates with periodic unevenness
Solution Approach 1:
A sensor continuously monitors the condensing groove for impurity accumulation and provides feedback to the control system. When impurities are detected, the system automatically activates the cleaning rod to remove them, maintaining yarn quality without interrupting production
Solution Approach 2:
The system automatically detects and cleans its own condensing groove without external intervention, maintaining optimal cleaning conditions continuously during operation to prevent yarn quality degradation while keeping production running

AI summary
The invention relates to a rotor spinning device self-cleaning structure and a textile machinery as well as to a self-cleaning operation method, wherein the rotor spinning device self-cleaning structure comprises a spinning device that includes a cup insert for conveying cotton fibers, and a rotor. The rotor includes a condensing groove for forming a yarn, and includes a cleaning rod that can extend into and clean the condensing groove of the rotor when the rotor is in an operating state, and a driving device for driving the cleaning rod to operate. In addition, the rotor self-cleaning method comprises a rotor spinning device self-cleaning structure as described above, when the rotor is to be cleaned, the driving device drives the cleaning rod to move from an initial operating position to a cleaning operating position in which the cleaning rod is in contact with the condensing groove of the rotor in the rotating operating state. The invention can realize the cleaning of the rotor without stopping the machine and has a good cleaning effect, and at the same time can ensure the production efficiency of the textile machinery with the self-cleaning structure and improve the production benefit.
