Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rope fabric dyeing machines face issues with inconsistent fabric conveyance speed, potential jamming, and uneven fabric deposition, leading to reduced throughput and quality of dyeing due to variations in fabric material and environmental conditions.
Innovation Solution
A conveyor-driven fabric dyeing machine equipped with a fabric circulation detection idler and movement sensor, controlled by a computer program, adjusts conveyor speed and angle to maintain stable fabric circulation, preventing jamming and ensuring uniform deposition, thereby enhancing throughput and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveyor speed is increased to improve throughput, then productivity increases, but fabric may get jammed or excessively stretched causing damage
Solution Approach 1:
The patent employs sensors to detect fabric circulation status and conveyor speed, feeding this information back to the control system. The control system automatically adjusts conveyor speed based on detected fabric conditions, preventing jamming and overstretching while maintaining optimal throughput. This closed-loop feedback mechanism resolves the contradiction between high productivity and reliable fabric circulation.
2Reliability
If the conveyor speed is reduced to prevent fabric damage, then fabric circulation stability improves, but productivity decreases
Solution Approach 1:
The patent implements dynamic speed control where the conveyor speed is not fixed but automatically adjusted in real-time based on fabric circulation conditions detected by sensors. The control system modulates conveyor speed to match actual fabric processing needs, enabling high productivity when conditions are favorable and preventing damage when circulation becomes unstable, thus resolving the static trade-off between reliability and productivity.
3Manufacturing precision
If the fabric entry angle into the dyeing tube is not adjusted, then device complexity is reduced, but fabric circulation becomes unstable causing uneven deposition
Solution Approach 1:
The patent incorporates a fabric management device that pre-adjusts the fabric entry angle into the dyeing tube before the fabric enters the dyeing process. This preliminary adjustment ensures stable fabric circulation and uniform deposition from the outset, preventing circulation instability and uneven dye distribution. The angle adjustment mechanism is integrated into the existing conveyor system, minimizing additional complexity while achieving precise fabric positioning.
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
The system automatically corrects or halts conveyor operation to prevent fabric damage and machine breakdown, ensuring consistent dyeing speed, smooth circulation, and increased dyeing efficiency by stabilizing fabric movement and deposition.
Implementation Method 1
a fabric circulation detection idler and a fabric movement sensor are mounted and control is conducted with a computer program so that when the fabric circulation detection idler detects fabric is not in movement
Implementation Method 2
when the fabric movement sensor detects the fabric moves excessively fast or slow or gets jamming and stops
Implementation Method 3
the conveyor is controlled to automatically adjust the operation speed thereof or even to stop the operation
Implementation Method 4
the rear fabric guide adjusts the angle of the fabric entering the conveyor to make the circulation of the fabric stable
Implementation Method 5
the fabric management device functions to have the fabric regularly, orderly, and uniformly deposited and accumulated on the conveyor

AI summary
A circulation protection device is provided for a conveyor-driven fabric dyeing machine that includes a machine body having a front end in which a fabric circulation detection idler and a fabric movement sensor are mounted and a rear end in which a rear fabric guide and a fabric management device are mounted. Control is conducted with a computer program so that when the fabric circulation detection idler detects the fabric is not in movement, the conveyor is shut down; and when the fabric movement sensor detects the fabric is moving excessively fast or slow or gets jamming and stopped, the conveyor is controlled to automatically adjust the speed thereof or stops operation. When the fabric falls from a dyeing tube down to a conveyor, the rear fabric guide adjusts an entry angle of the fabric and the fabric management device allows the fabric to be orderly deposited on the conveyor.
