Heat Roller and Gear Transmission in Layer Transfer Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional layer transferring devices face challenges in transmitting driving force to a pressure roller located on a cover while allowing for the replacement of multilayer films and preventing excessive heat application to the film.
Innovation Solution
The device incorporates a main casing with an opening, a pivotally movable cover, a pressure roller, a heat roller, and gear transmission systems, enabling the cover to close and open, allowing film replacement and heat roller positioning to avoid excessive heat application, with a motor-driven gear system that transmits force to the pressure roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressure roller is provided at the cover to enable film replacement, then the ease of operation is improved, but the device complexity increases due to the need for driving force transmission mechanisms
Solution Approach 1:
The second transmission gear is positioned between the heat roller and the pivot axis of the cover, nesting the gear mechanism within the existing cover structure. This allows the pressure roller to be driven through a compact arrangement that utilizes the cover's pivot motion, reducing the need for additional external transmission components while maintaining ease of film replacement operation.
2Object-generated harmful factors
If the heat roller is made movable to prevent excessive heat application, then the object-generated harmful factors are reduced, but the device complexity increases due to additional positioning mechanisms
Solution Approach 1:
The heat roller is designed to be movable in a direction crossing the first direction (perpendicular to the cover pivot axis), allowing it to dynamically adjust its position between proximity to and separation from the pressure roller. This dynamic positioning enables the system to prevent excessive heat application by separating the rollers when not in use, while maintaining a compact structure that leverages the cover's pivot motion for positioning.
3Ease of operation
If the cover is made pivotally movable for film replacement, then the ease of operation is improved, but the reliability of driving force transmission may deteriorate due to intermittent gear engagement
Solution Approach 1:
The second transmission gear is positioned between the heat roller and the pivot axis of the cover, ensuring that the gear engagement is established before the cover reaches its extreme positions. This preliminary positioning of the gear mechanism ensures continuous and reliable driving force transmission to the pressure roller throughout the cover's pivot motion, preventing intermittent disengagement while maintaining ease of operation.

AI summary
A layer transferring device includes: a main casing having an opening and accommodating a heat roller, a motor, and a first transmission gear therein; a film cartridge; and a cover at which a pressure roller and a second transmission gear is provided and movable about a pivot axis to open and close the opening. The heat roller is movable toward and away from the pressure roller when the cover is closed. When the film cartridge is attached to the main casing and the cover is closed, the multilayer film contacts and passes through between the pressure roller and the heat roller. When the cover is closed, the first transmission gear for receiving a driving force from the motor and the second transmission gear for transmitting a driving force to the pressure roller are positioned between the pivot axis and the heat roller and in meshing engagement with each other.
