Solution Overview
Problem
Existing film patterning systems using co-axially stacked metal screens face challenges in precision and cost due to the complexity of manufacturing seamless cylindrical screens and difficulties in assembling them for intimate contact, leading to increased manufacturing costs and assembly issues.
Innovation Solution
A film patterning system comprising a first and second rotary member with adjustable positions to facilitate mounting and tightening of circumferentially stacked screen molds, allowing for precise alignment and patterning of plastic films using a suctioning mechanism, where the screen molds can be made from metal or heat-resistant plastics, enabling flexible and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If co-axially stacked metal screens are used for film patterning, then intimate contact between screens is achieved, but manufacturing precision requirements increase and costs rise
Solution Approach 1:
The invention changes the dimensional parameters of the screen molds by providing adjustable positioning mechanisms that allow the outer diameter of the inner screen mold and inner diameter of the outer screen mold to be independently adjusted. This eliminates the requirement for substantially equal diameters and enables intimate contact without high manufacturing precision
Solution Approach 2:
The invention introduces adjustable and movable positioning mechanisms that allow the relative positions of stacked screen molds to be dynamically adjusted. This enables the screen molds to be positioned to achieve intimate contact during operation, rather than requiring fixed precise manufacturing tolerances
2Reliability
If co-axially stacked metal screens are used for film patterning, then intimate contact between screens is achieved, but assembly difficulties arise
Solution Approach 1:
The invention introduces adjustable positioning mechanisms that allow the screen molds to be easily positioned and adjusted during assembly. The movable support structures enable operators to slide and position screen molds into correct positions without requiring high precision sleeving operations
Solution Approach 2:
The invention divides the screen mold assembly into separate, independently adjustable components. Each screen mold can be positioned and adjusted separately on its support structure, simplifying the assembly process compared to requiring precise integration of co-axial components
3Manufacturing precision
If adjustable rotary members with movable supports are used, then alignment precision of screen molds is improved, but device complexity increases
Solution Approach 1:
The invention uses simple movable support structures that can slide along the rotary members to achieve positioning. The adjustability is achieved through basic mechanical movements rather than complex mechanisms, maintaining simplicity while enabling precise alignment
Solution Approach 2:
The positioning mechanism allows the screen molds to be self-adjusted to the correct positions. The movable supports enable operators to directly position the screen molds without requiring complex external adjustment mechanisms, simplifying the overall device structure

AI summary
A film patterning system includes: a first rotary member having a first shaft that defines a first axis, and a cylindrical first screen mold that is rotatable about the first axis; a second rotary member spaced apart from the first rotary member, having a second shaft that defines a second axis parallel to the first axis, and rotatable about the second axis; a second screen mold trained on the first and second rotary members and circumferentially stacked on the first screen mold; and a suctioning box mounted in the first rotary member for suctioning the film that is guided onto the second screen mold.
