Round Baler Net Wrap With Reduced Knots for Cleaner Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing round baler nets face issues with material recycling due to high contaminant retention, particularly organic residues, which are difficult to remove during mechanical recycling, leading to low-quality recycled materials.
Innovation Solution
A round baler net wrap design with fewer first chains and reduced knots per meter, utilizing a specific thread configuration to minimize contaminant retention and enhance cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the net uses more first chains and more knots per metre (prior art configuration), then the net provides adequate structural coverage and containment, but the amount of fodder retained by the net increases, leading to higher contaminant content that is difficult to eliminate during recycling
Solution Approach 1:
The patent changes the structural parameters of the net by reducing the number of first chains from 25 to 17 and reducing knots per metre from greater than 33 to less than 22. This parameter optimization maintains adequate structural coverage while significantly reducing fodder retention and contaminant content, thereby resolving the contradiction between structural integrity and contaminant reduction
2Productivity
If the net comprises more first chains (25 chains in prior art), then the net provides comprehensive coverage, but the production efficiency decreases and the net becomes more complex to manufacture
Solution Approach 1:
The patent optimizes the number of first chains from 25 to 17, which simplifies the net structure and increases production efficiency. This parameter change reduces manufacturing complexity while maintaining adequate coverage through optimized chain spacing of 7.69 cm, thereby resolving the contradiction between productivity and device complexity
3Strength
If the net has more knots per metre (greater than 33 in prior art), then the net provides continuous structural support, but the net becomes more fragile and resistant to failure decreases
Solution Approach 1:
The patent reduces knots per metre from greater than 33 to less than 22, eliminating the fragility associated with excessive knotting. This parameter change improves net durability and reliability while maintaining structural support through optimized first chain configuration and spacing, thereby resolving the contradiction between strength and reliability

AI summary
A round baler net wrap (1) comprises a plurality of first chains (2) extending along a longitudinal direction (X-X), a plurality of second chains each arranged between two first chains (2) and defined by a plurality of segments (4), each fixed to two adjacent first chains (2). The net (1) is characterized in that each first chain (2) is spaced from the adjacent first chain (2) by at least 5.08 centimetres.
