Removable Ink Container with Integrated Heating for Screen Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for providing printing ink on printing units, particularly in screen printing processes, face challenges in efficiently changing ink types and maintaining ink properties, with complex heating and pumping systems that complicate cleaning and require significant effort and resources.
Innovation Solution
A device featuring an interchangeable container system with a separate heating and pumping mechanism, allowing for quick ink changes and continuous refilling without altering the ink's properties, where the heating and pumping functions are structurally distinct to facilitate easy cleaning and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a complex heating and pumping system is integrated into the ink container, then ink can be continuously supplied and heated, but the device becomes difficult to clean and requires significant effort to change ink types
Solution Approach 1:
The device is divided into separate functional modules: a removable ink container (31) that can be independently detached from the holder (33), separating the storage function from the heating and pumping functions. This segmentation allows the container to be quickly replaced for ink changes without cleaning the heating system, while the holder retains the heating device (39) and pump (48) for continuous operation.
Solution Approach 2:
The ink container (31) is extracted as a separate, removable component from the holder (33). The container can be detached without tools and replaced quickly, allowing ink changes to be performed in seconds. The heating device (39) and pump (48) remain in the holder, continuing to maintain ink temperature and supply functionality.
2Reliability
If the ink container is fixed and integrated into the holder, then heating and pumping functions are maintained, but ink changes require significant effort and time
Solution Approach 1:
The ink container (31) is designed with dynamic characteristics, allowing it to be easily inserted into and removed from the holder (33). The container can be quickly detached and replaced without tools, enabling rapid ink changes. The holder (33) maintains the heating device (39) and pump (48) to ensure continuous and reliable ink supply and temperature control.
3Temperature
If a separate heating device is used for the container, then ink temperature is controlled, but the device structure becomes more complex
Solution Approach 1:
The heating device (39) is merged with the holder (33) structure, where the holder serves dual purposes: supporting the removable ink container (31) and providing heating functionality through an integrated heating element. This combination eliminates the need for a separate heating device attached to the container, simplifying the overall structure while maintaining temperature control.
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
Enables rapid ink changes within seconds, is cost-effective, and simplifies the cleaning process, ensuring continuous operation with minimal disruption, while maintaining ink quality through controlled heating and metering.
Implementation Method 1
at least part of a quantity of printing ink arranged in the container (31) in the region of its outlet (32) is liquefied or at least liquefiable by a first quantity of heat generated by a first heating device (39) of the holder (33) and introduced into the container (31)
Implementation Method 2
an outlet pipe (41) with a second heating device (44), by which at least part of a quantity of printing ink conducted through the outlet pipe (41) is replaced by a second quantity of heat generated by the second heating device (44) and introduced into this quantity of printing ink in its liquefied or liquid state
