Adhesive Tape Cartridge Acute Angle Peeling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing adhesive tape cartridges fail to reliably peel the separation material layer due to inadequate peeling angles, resulting in inefficient separation material peeling.
Innovation Solution
The adhesive tape cartridge design includes a peeling part positioned further downstream than the take-up position of the separation material roll, allowing the separation material layer to be peeled at an acute angle rather than directly horizontal, ensuring effective peeling and winding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the separation material layer is peeled directly horizontally at 90 degrees with respect to the feeding path, then the peeling structure is simple, but the peeling reliability is insufficient
Solution Approach 1:
The peeling part is positioned further downstream than the take-up position of the separation material roll, changing the peeling geometry from a direct horizontal 90-degree peeling to an acute angle peeling configuration. This spatial arrangement in another dimension enables the separation material layer to be peeled at an acute angle relative to the feeding path, thereby improving peeling reliability without significantly increasing structural complexity
2Reliability
If the peeling part is positioned further downstream than the take-up position, then the peeling angle becomes acute and peeling reliability improves, but the device length increases
Solution Approach 1:
Instead of increasing the cartridge length along the feeding path, the invention positions the peeling part further downstream in a manner that creates an acute angle peeling configuration. This utilizes spatial arrangement in another dimension to achieve reliable peeling while minimizing the increase in overall cartridge length
