Corrugated Board Splicer With Direct Adhesive Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of double-sided adhesive tapes in splicers for corrugated board production is costly, environmentally polluting, and requires a high consumption of materials, leading to waste and operational inefficiencies.
Innovation Solution
A splicer that applies adhesive in liquid or pasty form directly onto the web material, eliminating the need for double-sided adhesive tape, and includes a dispensing member to distribute adhesive transversely across the web material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If double-sided adhesive tape is used for splicing paper webs, then the splicing function is achieved, but the material cost increases and environmental pollution occurs
Solution Approach 1:
The patent extracts and removes the adhesive tape substrate and protective films from the splicing system, retaining only the necessary adhesive function. The dispenser applies adhesive directly to the paper web edge without requiring a tape carrier, eliminating the substrate and protective layer waste while maintaining the splicing function.
Solution Approach 2:
The patent changes the physical state and application method of the adhesive from a pre-formed tape with pressure-sensitive adhesive to a dispensable liquid or paste adhesive. This parameter change allows precise control of adhesive application, reducing material consumption while achieving the same splicing reliability.
2Reliability
If double-sided adhesive tape is used for splicing, then the splicing function is achieved, but the cost increases
Solution Approach 1:
The patent eliminates the expensive tape substrate and protective films from the system, keeping only the essential adhesive component. This extraction of non-essential elements significantly reduces material cost while preserving the splicing function through direct adhesive application.
Solution Approach 2:
The patent replaces the expensive reusable tape structure with a simple, low-cost adhesive dispensing system that applies adhesive as needed. The adhesive itself is used in minimal quantities and can be replenished from a reservoir, making the overall system more cost-effective than continuous tape consumption.
3Reliability
If double-sided adhesive tape is used, then splicing is achieved, but waste material is generated
Solution Approach 1:
The patent removes the waste-generating components (tape substrate, protective films) from the splicing process, retaining only the functional adhesive element. This extraction eliminates the generation of non-biodegradable waste materials while maintaining splicing reliability through direct adhesive application to the paper web.
4Reliability
If double-sided adhesive tape with protective layers is used, then splicing function is achieved, but device complexity increases
Solution Approach 1:
The patent extracts and removes the complex multi-layer tape structure (substrate, adhesive layers, protective films) and replaces it with a simple dispensing system that applies adhesive directly. This simplification reduces device complexity while maintaining the splicing function through controlled adhesive application.
