Solution Overview

Problem

Existing dry fiber structure manufacturing apparatuses face inefficiencies in removing paper dust from transportation rollers, particularly where dust is more likely to accumulate, due to fixed and uniformly contacting brushes that fail to effectively clean all areas.

Innovation Solution

A cleaning apparatus with a rotating cleaning roller and a remover that rotates on a different axis, specifically designed to target and remove paper dust from areas where it is most likely to accumulate, ensuring thorough cleaning of the pressure portion in the fiber structure manufacturing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fixed brush is used to clean the transportation roller, then the brush structure is simple, but the paper dust removal efficiency is insufficient

Engineering Contradiction:
Improvepaper dust removal efficiencyVSAvoidcleaning apparatus structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The brush is changed from a fixed structure to a rotating structure. The cleaning roller rotates about a first rotation axis, enabling dynamic cleaning action that significantly improves paper dust removal efficiency compared to static brushes while maintaining reasonable structural complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A remover rotates about a second rotation axis extending in a direction different from the first rotation axis, adding a dimensional aspect to the cleaning action. This multi-axis rotation creates enhanced cleaning effectiveness by attacking paper dust from multiple directions simultaneously

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If a brush contacts the entire area of the transportation roller, then the cleaning coverage is comprehensive, but the paper dust removal is insufficient in areas where dust is more likely to attach

Engineering Contradiction:
Improvepaper dust removal efficiencyVSAvoidcleaning coverage uniformity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The cleaning apparatus differentiates between different areas of the cleaning roller. The remover specifically targets the second area where paper dust is more likely to attach, applying enhanced cleaning action to this high-dust region while maintaining appropriate cleaning for other areas, thus optimizing overall dust removal efficiency

Inventive Principle:
Principle #3Local quality

AI summary

A cleaning apparatus includes a cleaning roller configured to rotate about a first rotation axis to clean a component to which paper dust is attached, the cleaning roller having a first area and a second area that is adjacent to the first area in a direction along the first rotation axis and to which more paper dust is attached than to the first area, and a remover configured to rotate about a second rotation axis extending in a direction different from the first rotation axis and configured to come in contact with at least a portion of the second area to remove the paper dust from the second area.
