Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated board plants face issues with suboptimal adhesive connections between single-sided corrugated board webs and printing quality, requiring improvements in space efficiency and print quality while minimizing energy consumption.
Innovation Solution
A corrugated board plant design with a liner web printing arrangement positioned between the liner web delivery device and the double-sided corrugated board production, utilizing a digital inkjet printing system for high-quality printing on both sides of the liner web, combined with a compact layout and efficient glue application to ensure strong adhesion at low processing temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a traditional printing arrangement is used in the corrugated board plant, then the printing process can be performed, but the print quality is unsatisfactory
Solution Approach 1:
The liner web is printed before being fed into the corrugating device. This preliminary printing action allows the ink to be applied to the smooth surface of the liner web before it undergoes corrugation, ensuring high print quality while maintaining the integrity of the adhesive connection process
Solution Approach 2:
The printing process is separated from the corrugation process. The liner web is printed in a dedicated printing arrangement upstream of the corrugating device, allowing independent optimization of both printing quality and corrugation quality without mutual interference
2Device complexity
If the printing arrangement is placed in the traditional position, then the process flow is simple, but the adhesive connection between the corrugated board web and laminating web is not optimal
Solution Approach 1:
The liner web is printed and then fed into the corrugating device in sequence. This preliminary printing followed by corrugation ensures that the printed liner web maintains its structural integrity and adhesive properties, leading to optimal adhesive connection in the final laminating process
3Manufacturing precision
If more processing equipment is added to improve print quality and adhesive strength, then the production quality improves, but the space required increases
Solution Approach 1:
The printing arrangement is integrated into the existing corrugated board plant by positioning it upstream of the corrugating device. This merging of functions allows the printing process to be incorporated without requiring a completely separate facility, thus improving production quality while minimizing additional space requirements
Solution Approach 2:
The liner web serves multiple functions: it is printed for quality branding, then corrugated for structural integrity, and finally used for adhesive bonding. This multi-functionality of the liner web allows the system to achieve multiple quality objectives without adding proportionally more equipment
