Selective-Coated Conveyor Belt for Air-Permeable Cardboard Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belts used in transporting and stacking cardboard blanks are impermeable and have sharp, impact-prone edges due to their material-removing processing, leading to inefficiencies and potential damage.
Innovation Solution
A conveyor belt design featuring selectively coated areas with coating strips made of polymer materials like polyurea, allowing for optimal friction and air permeability, while avoiding sharp edges by using a spiral link carrier and strategically placed uncoated areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a complete closed surface coating is applied to the carrier, then conveying efficiency is improved through optimal friction, but air permeability is lost and sharp edges are created
Solution Approach 1:
The conveyor belt surface is segmented into alternating coated and uncoated regions along the transverse direction. The coated regions provide friction for conveying, while the uncoated regions maintain air permeability and eliminate sharp edges, resolving the contradiction between conveying efficiency and harmful effects
Solution Approach 2:
Different regions of the conveyor belt surface are given different properties: coated regions have high friction for material conveyance, while uncoated regions remain porous and edge-free. This local differentiation allows the belt to simultaneously achieve optimal conveying and avoid harmful effects
2Reliability
If material is removed by grinding to create grooves, then sealing and guidance are improved, but sharp impact-prone edges are created
Solution Approach 1:
Instead of removing material to create grooves (which creates sharp edges), the invention applies coating material selectively to create raised coated regions. This inverted approach achieves the same sealing and guidance functions while the uncoated regions between coated areas provide rounded, impact-resistant transitions
3Productivity
If a continuous coating is applied across the entire carrier surface, then conveying properties are optimized, but air permeability is completely blocked
Solution Approach 1:
The coating is applied in a segmented pattern with alternating coated and uncoated regions across the transverse direction of the belt. This segmentation allows air to pass through the uncoated regions while the coated regions provide the necessary friction for conveying
Solution Approach 2:
The belt surface exhibits local quality variation where coated regions provide high friction for material handling, while uncoated regions maintain the carrier's natural air permeability, allowing both functions to coexist
