Solution Overview

Problem

Existing devices for separating materials of different flowability face challenges in maintaining a consistent gap width and aligning the lateral surfaces of the pressure roller and hollow drum, leading to suboptimal separation quality and difficulty in adapting to varying separation processes.

Innovation Solution

A device with a position-adjustable bearing block that securely mounts the drive roller on the housing base, allowing for precise adjustment of the gap width and alignment, ensuring the drive roller remains parallel to the hollow drum, even under varying forces, through a pivotable design with locking and adjusting mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the press belt and hollow drum form a feed wedge for material separation, then separation function is achieved, but the gap width becomes difficult to adjust and align parallelly

Engineering Contradiction:
Improvegap width consistencyVSAvoidgap adjustment difficulty
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The bearing block is made pivotable relative to the housing base about a pivot axis, allowing dynamic adjustment of the drive roller position. This enables the gap width to be adjusted and aligned parallelly to the hollow drum outer surface by pivoting the bearing block, resolving the contradiction between precision and ease of adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pivotable bearing block allows changing the positional parameters of the drive roller relative to the hollow drum. By rotating the bearing block about the pivot axis, the gap width can be precisely controlled and maintained constant across the entire gap, achieving both precision and adjustability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the drive roller is securely mounted to withstand high forces, then reliability is improved, but gap width adjustment becomes restricted

Engineering Contradiction:
Improvedrive roller mounting stabilityVSAvoidgap width adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bearing block combines secure mounting capability with pivotability. It can be fixed in a locked position to withstand high forces during operation, yet pivoted to adjust the gap width before operation. This resolves the contradiction between reliability and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gap width and alignment can be adjusted in advance by pivoting the bearing block before the separation process begins. Once adjusted, the bearing block can be locked in position to maintain stability during high-force operation, achieving both adaptability and reliability.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the gap width is made variable to adapt to different materials, then versatility is improved, but alignment precision deteriorates

Engineering Contradiction:
Improvematerial adaptation capabilityVSAvoidalignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The pivotable bearing block enables variable gap width adjustment while maintaining alignment precision. By pivoting the bearing block about a fixed pivot axis, the drive roller can be positioned at different gap widths while keeping its outer surface parallel to the hollow drum outer surface, resolving the contradiction between versatility and precision.

Inventive Principle:
Principle #15Dynamics
