High-Temperature Furnace Shutter for Bobbin Chamber Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing high-temperature processing furnaces for reinforcement fibers require time-consuming temperature adjustments and vacuuming processes during the reinforcement fiber joining operation, which elongates the time needed to resume the high-temperature process, thereby reducing productivity.
Innovation Solution
The high-temperature processing furnace incorporates shutters to control communication paths between the furnace body and bobbin chambers, allowing for synchronized rotation and vacuuming without temperature adjustments, enabling direct connection of the feed and take-up bobbins through a guide cord loop, thus automating the fiber joining process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feed bobbin becomes empty during high temperature process and joining operation is carried out by detaching and reattaching bobbins, then the reinforcement fiber can be joined, but the internal temperature must be decreased and increased again, which elongates the time needed to resume the high-temperature process
Solution Approach 1:
The furnace is divided into a high-temperature processing chamber and a bobbin chamber that can be independently vacuumed and temperature-controlled. This segmentation allows the bobbin replacement to occur in the bobbin chamber without affecting the temperature and vacuum state of the high-temperature processing chamber, thus resolving the contradiction between ease of operation and time loss.
2Reliability
If the inside of the furnace body is vacuumed and temperature is adjusted during bobbin replacement, then the vacuum atmosphere is maintained for high-temperature processing, but the productivity is reduced due to the time required for these operations
Solution Approach 1:
The system is segmented into two independently controllable chambers: the high-temperature processing chamber that maintains vacuum and temperature, and the bobbin chamber that can be opened to atmosphere for bobbin replacement. This allows reliable vacuum atmosphere maintenance in the processing chamber while improving productivity by eliminating the need to vacuum and reheat the entire furnace during bobbin changes.
Solution Approach 2:
Empty bobbins are pre-loaded into the bobbin chamber and vacuumed beforehand. When a full bobbin is replaced, the pre-vacuumed empty bobbin is already in position, eliminating the need for time-consuming vacuuming and temperature adjustment operations during the replacement process, thus maintaining both reliability and productivity.
3Adaptability or versatility
If the feed bobbin is detached and reattached during the process, then continuous production is enabled, but the complex operations of temperature adjustment and vacuuming reduce operational efficiency
Solution Approach 1:
By segmenting the furnace into a high-temperature processing chamber and a separately vacuumed bobbin chamber, the system enables continuous production through straightforward bobbin replacement operations. The bobbin chamber can be opened to atmosphere for easy bobbin changes while the processing chamber maintains its vacuum and temperature, making the operation simple and efficient.
