Die Lip Adjustment Cross-Bar Mechanism for Uniform Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing die adjustment mechanisms fail to provide bi-directional, quick, accurate, and repeatable adjustment of the gap between lips of adjacent die bodies, especially for wide dies, and struggle to maintain a uniform gap across the die width.
Innovation Solution
A die adjustment system comprising a cross-bar, linear moving members, slide fasteners, pivoting members, and a sliding member, where the sliding member connects to pivoting members via pivot fasteners, allowing for single-point adjustment of the flexible lip's movement about a hinge, enabling precise and repeatable gap adjustments across the die width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional link mechanisms are used to adjust the lip gap, then the structure is simple, but the adjustment speed and accuracy are insufficient
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the die body can be quickly repositioned between closed and open states using a movable linkage system. This allows rapid lip gap adjustment without complex multi-stage mechanisms, resolving the contradiction between adjustment speed and mechanism complexity.
Solution Approach 2:
The adjustment mechanism is segmented into distinct functional components: the movable die body, linkage arms, and positioning members. This segmentation allows each component to perform its specific function efficiently, enabling quick adjustment while maintaining overall system simplicity.
2Manufacturing precision
If traditional adjustment mechanisms are used, then the structure is straightforward, but the uniformity of gap across die width is poor
Solution Approach 1:
The patent introduces a cross-bar linkage system that distributes the adjustment force uniformly across the width of the die. This dimensional approach ensures that the lip gap remains uniform from one end of the die to the other, achieving high manufacturing precision without overly complicating the adjustment system.
Solution Approach 2:
The linkage mechanism serves multiple functions simultaneously: it adjusts the lip gap, maintains uniformity across the die width, and enables quick repositioning. This multi-functionality achieves high precision adjustment without proportionally increasing system complexity.
3Manufacturing precision
If multiple adjustment points are used to achieve uniform gap, then the gap uniformity improves, but the adjustment time increases
Solution Approach 1:
The patent merges multiple adjustment functions into a single coordinated linkage system. By combining the adjustment points through a unified linkage mechanism, the system achieves uniform gap adjustment across the entire die width through one coordinated motion, eliminating the need for separate adjustment operations at multiple points.
4Productivity
If complex adjustment mechanisms are used to achieve quick adjustment, then the adjustment speed improves, but the device complexity increases
Solution Approach 1:
The patent employs a dynamic linkage system that allows rapid movement between adjustment positions. The movable die body and linkage arms create a mechanically efficient system that achieves quick adjustment without requiring complex control mechanisms or multiple stages, thus improving productivity while maintaining reasonable device complexity.

AI summary
The invention comprises a die apparatus including a flexible lip for adjusting a gap between the flexible lip and a second lip. The apparatus include a cross-bar contacting the lip and extending substantially the length of the lip, where the cross-bar is connected to linear moving members. The linear moving members may be moved, for instance, through pivoting pivot members. The pivoting members may pivot by adjusting a slide bar. As a result, the dimensions of the gap may be changed by moving the slide bar in a first direction or a second direction.
