Tray Sealing Machine Movable Hood Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tray sealing machines face issues with maintenance and performance due to complex upper tool components with limited cable cross-sections for electrical supply lines, leading to reduced heating capacity and durability from repeated motions.
Innovation Solution
A tray sealing machine design featuring a movable hood relative to the frame and sealing component carrier, with gas connections and lines configured to minimize or eliminate motions during the sealing process, allowing for larger cable cross-sections and increased heating performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electrical supply lines with large cable cross-sections are used for high heating power, then heating capacity is improved, but cable durability deteriorates due to repeated bending motions
Solution Approach 1:
The patent inverts the traditional configuration by making the hood movable instead of the sealing component carrier. This causes the gas connections to remain stationary relative to the sealing component, eliminating repeated bending motions from electrical supply lines while still allowing the sealing chamber to be formed and sealed effectively
2Adaptability or versatility
If the upper tool components are made completely movable for flexibility, then adaptability is improved, but device complexity increases due to gas lines and electrical supply lines
Solution Approach 1:
The patent segments the upper tool into two distinct parts: a movable hood that forms the sealing chamber, and a stationary sealing component carrier that holds the sealing component. This segmentation allows the hood to move for adaptability while the sealing component carrier remains fixed, simplifying the gas and electrical line connections to only the stationary part

Function Achieved in This Case
This design enhances durability and heating performance by reducing the risk of damage to electrical supply lines and enabling higher heating capacity while simplifying maintenance efforts.
Implementation Method 1
the line is used for the evacuation of the sealing chamber
Implementation Method 2
The heating capacity of heating elements depends on the current that they are supplied

AI summary
A tray sealing machine is provided with a frame on which a sealing tool is arranged. The sealing tool comprises a lower tool in which a tray to be sealed can be received and an upper tool including a hood, a sealing component arranged in the interior of the hood, and a sealing component carrier on which the sealing component is arranged. The hood is movable relative to the sealing component and has a gas connection configured for connection to a corresponding gas connection of the tray sealing machine. The lower tool and the hood are configured to form a sealing chamber in a closed state of the sealing tool. The sealing tool further comprises a line connecting the gas connection to the sealing chamber in the closed state. The hood is movable relative to the frame and the sealing component carrier is unmovable relative to the frame.
