Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning needle holder plates in knitting machines are labor-intensive, time-consuming, and costly, often requiring manual removal and reinstallation of components, and existing ultrasonic machines are inefficient and require long operating cycles.
Innovation Solution
A machine designed to clean needle holder plates with a sliding drawer mechanism, a washing tank, and dispensing means for pressurized washing fluid, allowing for quick and effective cleaning without complete removal of the plates, using a hydraulic circuit with filtering elements to optimize cleaning power and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning methods are used, then cleaning can be performed, but it requires complete removal of needle holder plates and all needles and actuator rods, consuming long time and qualified personnel
Solution Approach 1:
The cleaning machine divides the needle holder plate into multiple cleaning zones with different cleaning methods (ultrasonic cleaning for some areas, jet spray cleaning for others), allowing simultaneous cleaning of different sections without complete disassembly
Solution Approach 2:
The patent introduces a specialized cleaning machine as an intermediary device that handles the cleaning process, eliminating the need for manual cleaning and reducing machine stoppage time while maintaining cleaning effectiveness
2Reliability
If traditional ultrasonic cleaning machines are used, then cleaning can be performed, but they require complete removal of needle holder plates and needles, and operating cycles last several hours
Solution Approach 1:
The patent combines ultrasonic cleaning technology with jet spray cleaning technology in a single machine, allowing simultaneous operation of both cleaning methods on different zones of the needle holder plate, thereby reducing total cleaning time while maintaining high cleaning quality
Solution Approach 2:
The cleaning machine applies ultrasonic cleaning selectively to specific zones where it is most effective, while using jet spray cleaning for other areas, avoiding the need for complete disassembly and reducing overall processing time
3Reliability
If manual cleaning operations are performed, then cleaning can be accomplished, but it represents high costs in terms of labour and knitting machine management
Solution Approach 1:
The cleaning machine is designed to be easily loaded and unloaded with automatic cleaning cycles, reducing the need for qualified personnel and minimizing manual intervention, thereby lowering labor costs while maintaining effective cleaning performance
