Outlet Element Welding Support for Flat Anvil Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding devices for packaging materials face challenges in achieving precise and compact welding of outlet elements, such as valves, to packaging materials while maintaining a flat anvil configuration and minimizing material complication post-welding.
Innovation Solution
A welding device with a support unit that includes a movably supported support element to exert a holding force on the anvil, allowing for precise positioning and movement of the anvil relative to the welding die, and a compact design that includes a hydraulic, pneumatic, or servo drive system to maintain the anvil in the welding position during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a welding device uses a fixed anvil configuration, then the device structure is simple, but the welding precision and adaptability are reduced
Solution Approach 1:
The anvil is designed with movable support elements that can adjust their position dynamically during the welding process. The support elements are configured to be movable relative to the holding element, allowing the anvil to adapt its configuration for precise welding while maintaining overall structural simplicity.
2Volume of moving object
If the anvil is made compact and flat, then the device size is reduced, but the holding force and stability during welding are compromised
Solution Approach 1:
The anvil is divided into a holding element and multiple movable support elements. This segmentation allows the compact holding element to maintain a flat, space-efficient design while the distributed support elements provide sufficient holding force through their collective action on the packaging material.
3Object-generated harmful factors
If the packaging material opening angle is minimized, then material complication is reduced, but the welding accessibility and process efficiency are affected
Solution Approach 1:
The support elements are arranged in a distributed pattern across the anvil surface, creating multiple zones for material engagement. This spatial arrangement allows the packaging material to be processed with minimal opening angle while maintaining welding accessibility through the distributed support structure.
