Ink Mist Collection Nozzle Layout for Vibration-Isolated Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink mist generated during printing contaminates the printing medium and printer, and the suction force for collecting the mist causes vibration that affects the ejection head's operation.
Innovation Solution
A printer configuration with a collection nozzle system where the nozzle exhaust part and suction duct intake part are separated, allowing airflow to collect ink mist without transmitting vibration to the ejection head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction source is placed near the ejection head to collect ink mist, then mist collection effectiveness is improved, but vibration is transmitted to the ejection head affecting ink ejection
Solution Approach 1:
The suction system is segmented into separate components: the collection nozzle is positioned near the ejection head to capture mist, while the suction fan is located remotely. The suction duct connects these separated components, allowing the system to maintain effective mist collection while preventing vibration transmission to the ejection head.
Solution Approach 2:
The suction duct acts as an intermediary element between the collection nozzle and the suction fan. It transmits the suction force from the fan to the nozzle while physically isolating the vibration source (fan) from the sensitive component (ejection head), thus mediating between mist collection effectiveness and ejection stability.
2Productivity
If the collection nozzle is positioned close to the ejection head, then mist collection efficiency is improved, but the structure becomes more complex
Solution Approach 1:
The collection nozzle is integrated with the ejection head assembly, combining the ink ejection function and mist collection function into a single coordinated unit. This integration allows the nozzle to be positioned optimally for mist collection while sharing structural support with the ejection head, thereby reducing overall system complexity despite the close positioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Vibration transmission from the suction source to the ejection head is suppressed, enabling effective ink mist collection near the ejection head while maintaining stable ink ejection.
Implementation Method 1
a suction source generating a suction force; an airflow flowing into the duct opening through the air exhaust opening from the air intake opening is generated by the suction force supplied to the duct opening
Data Source
AI summary
The nozzle exhaust part 43 and the exhaust connector 51 (the exhaust duct 5) are separated from each other. For this reason, transmission of vibration to the nozzle exhaust part 43 from the exhaust connector 51 is suppressed. As a result, it becomes possible to suppress transmission of vibration to the ejection head 121 from the fan unit 71 which generates the suction force for collecting a mist while collecting the mist near the ejection head 121 serving as a source of the ink mist.
