Glass Plate Bend-Breaking Machine Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glass plate bend-breaking machines often cause chipping or damage to the bend-broken surface of the glass plate due to collisions between the bend-broken cullet and the glass plate after press-breaking.
Innovation Solution
A glass plate bend-breaking machine with a flexible member, a supporting mechanism, an annular glass plate receiving surface, and a recess, where the press-breaking device presses the glass plate along the cut line from an upper side, avoiding direct contact with the glass plate receiving surface to prevent collisions and chipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the glass plate receiving surface is disposed inside the region surrounded by the bend-breaking line to support the glass plate, then the glass plate can be properly supported during press-breaking, but the bend-broken cullet can be pushed up by the receiving surface and collide against the glass plate product, causing chipping or damage
Solution Approach 1:
The glass plate receiving surface is segmented into an annular shape with a central recess, separating the support function from the push-up zone. The annular receiving surface supports the glass plate at its periphery while the central recess allows bend-broken cullet to fall through without being pushed up against the product glass plate.
Solution Approach 2:
Instead of having a solid receiving surface that pushes up cullet, the invention inverts the structure by creating a central recess that allows cullet to pass through. This inversion transforms the harmful push-up effect into a beneficial through-pass effect, eliminating chipping damage while maintaining support stability.
2Manufacturing precision
If the press-breaking device presses the glass plate from the upper side along the cut line, then the glass plate can be bend-broken along the desired line, but the press-breaking device may contact the glass plate receiving surface and cause misalignment or damage
Solution Approach 1:
The receiving surface is segmented into an annular shape with a central recess, creating a clear spatial separation between the support zone (annular region) and the press-breaking zone (central region). This segmentation allows the press-breaking device to operate in the central recess area without contacting the receiving surface, while maintaining precise bend-breaking along the cut line.
Solution Approach 2:
The invention introduces a vertical dimension solution by creating a recess (depth dimension) in the receiving surface. This vertical separation allows the press-breaking device to press down into the recess space without horizontal or vertical interference with the receiving surface, eliminating collision risks while preserving bending precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine effectively prevents collisions and chipping on the bend-broken surface by deflecting the glass plate at the recess, ensuring safe and efficient bend-breaking without damaging the glass plate.
Implementation Method 1
bend-breaking can be caused in the glass plate along the cut line owing to the deflection of the glass plate at the recess
