Staggered Crusher Duct System for Uniform Absorbent Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing wide absorbent bodies result in irregular thickness and increased manufacturing costs due to the need for wider crushers and pulp sheets, leading to poor crushing and uneven accumulation on the adsorbent molding section.
Innovation Solution
The device employs staggered crushers with overlapping configurations to ensure even fluff pulp accumulation on the adsorbent molding section, using a duct system to merge and uniformly distribute the fluff pulp, allowing for the use of all-purpose pulp sheets without increasing crusher width or manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the width of the crusher is increased to produce wider absorbent bodies, then the width of the absorbent body is improved, but the rotational shaft bends during crushing causing non-uniform crushing and manufacturing costs increase
Solution Approach 1:
The invention divides a single wide crusher into multiple smaller crushers arranged in parallel. Each crusher has its own rotational shaft and rotating blades, allowing independent operation. This segmentation prevents shaft bending issues while collectively producing wide absorbent bodies through combined output from multiple units.
2Area of stationary object
If the width of the crusher is increased to produce wider absorbent bodies, then the width of the absorbent body is improved, but manufacturing costs increase due to dedicated pulp sheets
Solution Approach 1:
By using multiple smaller crushers instead of one large crusher, the system can process standard-width pulp sheets through each unit. This eliminates the need for expensive dedicated wide pulp sheets, reducing material costs while achieving the desired wide absorbent body width through combined output.
3Area of stationary object
If a single wide crusher is used to produce wide absorbent bodies, then the width of the absorbent body is improved, but the fluff pulp accumulation becomes irregular causing thickness non-uniformity
Solution Approach 1:
Multiple smaller crushers each produce fluff pulp that is conveyed separately and then merged. This segmentation allows better control over the distribution and accumulation of fluff pulp from each unit, resulting in more uniform thickness across the width of the final wide absorbent body.
Solution Approach 2:
The invention merges the output from multiple crushers into a single combined flow that is then conveyed to the forming section. This merging process allows the fluff pulp from multiple sources to be uniformly distributed and accumulated, achieving consistent thickness across the width of the absorbent body.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables the production of wide absorbent bodies with uniform thickness and prevents irregularities and cost increases, extending the utilization range of existing crushers and maintaining even crushing efficiency.
Implementation Method 1
a duct in which the fluff pulp is carried by air
Implementation Method 2
the mixed flow is adsorbed and retained by an adsorbent molding section

AI summary
The present invention enables the formation of a wide absorbent body without an increase in production cost or the occurrence of poor crushing or thickness unevenness. A plurality of crushers (2, 3) are disposed in a mutually offset fashion in the axial direction (B) of a rotating blade (3a). The fluff pulp for crusher (2) is introduced into an upstream duct (5a), and the fluff pulp from crusher (3) is introduced into an upstream duct (5b). The fluff pulp air-conveyed through the upstream ducts (5a, 5b) flows together within a downstream duct (6), and is air-conveyed towards a rotating, fiber-stacking drum (7).
