Stamp Face Forming Apparatus with Selective Edge Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stamp-face forming technologies require large-scale apparatuses due to the need for thermal heads with heating elements to be pressed against stamp face materials attached to blocks, making them cumbersome and inefficient for forming stamps with precise control over heat distribution.
Innovation Solution
A stamp-face forming apparatus with plural heating elements that can selectively heat a porous stamp face material, which is detachably held in a holding body and coated with a film, allowing for controlled heat application to edge portions to be greater than non-porous areas, enabling efficient formation of stamp faces with easy removal from the holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the stamp face material is attached to a block and heated with a thermal head, then the stamp face can be formed, but the apparatus becomes large in scale and cumbersome
Solution Approach 1:
The invention separates the stamp face material from the block, allowing the material to be held in a holder rather than attached to a large block. This segmentation enables the heating elements to directly contact the stamp face material without requiring a large supporting structure, thus reducing apparatus size while maintaining formation precision.
Solution Approach 2:
The invention extracts the stamp face material from the block attachment and makes it detachably held in a holder. This extraction allows the material to be freely positioned and heated without being constrained by a large block, enabling precise heat application and reducing the overall apparatus scale.
2Stability of the object's composition
If uniform heat is applied to the entire stamp face material, then the material is heated evenly, but the edge portions cannot be properly sealed to prevent ink leakage
Solution Approach 1:
The invention applies different heat amounts to different regions of the stamp face material. Specifically, the edge portions are heated to a greater extent than the central portions, creating local quality differences. This ensures that the edges are properly sealed to prevent ink leakage while the central areas maintain appropriate porosity for ink absorption.
Solution Approach 2:
Instead of applying uniform heat throughout, the invention inverts the approach by concentrating heat on the edge portions while applying less heat to the central areas. This inverted heat distribution pattern achieves the desired sealing effect at the edges without compromising the overall functionality of the stamp face.
3Stability of the object's composition
If the stamp face material is tightly held in the holder, then the material remains stable during heating, but the material cannot be easily removed after formation
Solution Approach 1:
The invention employs a detachable holding mechanism that can dynamically adjust its grip on the stamp face material. During heating, the holder provides sufficient retention to maintain material stability. After heating, the detachable nature of the holder allows for easy material removal, thus satisfying both stability and ease of operation requirements through dynamic characteristic.
Solution Approach 2:
The invention changes the holding parameters of the stamp face material holder. The holder is designed with specific retention characteristics that provide strong enough grip during the heating process but allow for easy detachment afterward. This parameter optimization enables both material stability during formation and ease of removal after formation.

Implementation Method 1
the plate making apparatus holds the block with the stamp face material attached thereon and moves the plural heating elements of the thermal head so as to slide on the surface of the porous sheet of the stamp face material, while resiliently pressing the heating elements against the surface of the porous sheet, and selectively heats the plural heating elements to heat the stamp face material
Implementation Method 2
a conveying unit which conveys the stamp face material holder through the stamp-face forming unit in a conveyance direction
