Web Splicer Adhesive Dispensing to Replace Double-Sided Tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of double-sided adhesive tapes in splicers for corrugated board production is costly, environmentally harmful due to waste materials, and requires a double layer of pressure-sensitive adhesive, leading to high consumption and pollution.
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 reducing waste by using a bulk adhesive dispenser supported by a transverse slide with a cutting member for trimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If double-sided adhesive tape is used for splicing, then the splicing function is achieved, but adhesive consumption and cost increase
Solution Approach 1:
The invention changes the physical state of adhesive from pre-formed tape format to bulk liquid/pasty form, allowing direct application and precise control of adhesive quantity. This parameter change eliminates the need for adhesive carrier materials and protective films, reducing overall material consumption while maintaining splicing reliability
Solution Approach 2:
The invention extracts the adhesive from its traditional carrier material (the paper substrate of double-sided tape) and applies it directly in bulk form. This separation allows the adhesive to be applied only where needed on the web material edges, eliminating waste of adhesive and carrier material while preserving the splicing function
2Reliability
If double-sided adhesive tape is used, then splicing is achieved, but environmental impact increases due to waste materials
Solution Approach 1:
Changing adhesive from tape form to bulk form eliminates paper waste and protective film waste, reducing environmental impact while maintaining splicing reliability through direct adhesive application
Solution Approach 2:
The invention eliminates the need to discard adhesive carrier materials and protective films by applying adhesive directly in bulk form, thereby preventing waste generation at the source while maintaining effective splicing
3Reliability
If double-sided adhesive tape is used, then splicing is achieved, but device complexity increases
Solution Approach 1:
The invention removes the complex tape handling system (tape reel, tape application mechanism, protective film removal system) and replaces it with a simple bulk adhesive dispensing system, reducing device complexity while maintaining splicing reliability
Solution Approach 2:
Instead of applying adhesive through a pre-formed tape structure, the invention inverts the approach by directly dispensing bulk adhesive onto the web material edges, simplifying the application mechanism while achieving the same splicing function
