Adjustable Sliding Floor for Gentle Rope Textile Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing long-storage machines for textile goods face challenges in treating a wide range of textile materials due to varying coefficients of friction, leading to issues like fabric damage, wrinkles, and uneven treatment, as they often rely on fixed reel systems and sliding floors with predefined inclinations that are not adaptable to different materials.
Innovation Solution
The machine features an adjustable sliding floor inclination within the treatment container, allowing for customizable angles between 6 and 14 degrees, and a trough-shaped sliding floor that can be concavely curved, along with a transport nozzle arrangement that operates without a reel, enabling gentle handling of textile goods by minimizing tensile forces and optimizing liquor ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fixed reel system is used to drive the material strand, then the material can be transported through the treatment vessel, but surface damage occurs due to abrasion and fabric displacement from contact with the reel
Solution Approach 1:
The invention removes the reel component entirely from the system. Instead of using a mechanical reel to drive the material strand, the patent employs a transport nozzle assembly that propels the strand through the treatment vessel using a fluid medium, thereby eliminating the source of surface damage while maintaining transport functionality
Solution Approach 2:
The mechanical reel-based drive system is replaced with a fluid-dynamic transport system. The transport nozzle assembly uses a fluid medium (liquid or gas) to propel the material strand, substituting mechanical contact with fluid-based propulsion to avoid abrasion and surface damage

If a sliding floor with fixed inclination is used in the storage section, then material can be transported by gravity effect, but fabric compaction and wrinkles occur due to varying coefficients of friction for different textile materials
Solution Approach 1:
The sliding floor inclination is made adjustable rather than fixed. The patent incorporates a mechanism that allows the inclination angle of the sliding floor to be dynamically changed according to the specific textile material being processed, enabling optimization of the gravity effect for different friction coefficients and preventing fabric compaction and wrinkles
Solution Approach 2:
The inclination angle parameter of the sliding floor is made variable. By adjusting this geometric parameter according to the specific textile material's properties (particularly its coefficient of friction), the system optimizes material flow and prevents harmful effects like compaction and wrinkling
3Object-affected harmful factors
If the sliding floor is made concavely curved to prevent fabric compaction, then fabric handling is improved for some materials, but the design becomes less suitable for other textile types with different friction characteristics
Solution Approach 1:
The sliding floor geometry is made dynamically adjustable. Instead of a fixed concave curve that may not suit all materials, the patent allows the inclination angle to be changed, providing adaptability to different textile types while maintaining the benefit of reduced fabric compaction through optimized gravitational flow

Function Achieved in This Case
This design allows for the effective treatment of diverse textile materials with reduced fabric damage, minimized wrinkles, and improved shrinkage values, as it adjusts to the specific friction coefficients of different textiles, ensuring gentle handling and efficient processing across various types of goods.
Implementation Method 1
a transport nozzle assembly (14) arranged within it and capable of being supplied with a liquid and/or gaseous transport medium
Implementation Method 2
the sliding floor (16), which preferably has a friction-reducing surface on its upper side in contact with the material bundle, is inclined downwards at least in sections, from the sheeting elements at the material inlet side to the material outlet side of the storage section, in order to achieve a gravity effect that promotes the transport of the sheeted material bundle

AI summary
An apparatus for the treatment of strand-like textile material in the form of a continuous rope which is circulated during at least part of its treatment comprises an elongated substantially tubular treatment container (1) having a storage section which holds a folded rope pile (19). The storage section contains a gliding bottom (16) and means (11) for changing the incline of the gliding bottom (16) from its rope inlet side (18) to its rope outlet side.
