Dual-Side Jet Strip Cleaning Device for Hydro-Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for cleaning nozzle strips in water-jet needling systems are inefficient in terms of cleaning performance and handling, as they often require multiple passes and limited simultaneous exposure to high-pressure water for effective contamination removal.
Innovation Solution
The device employs two high-pressure nozzles with associated suction devices positioned on both sides of the nozzle strip, allowing simultaneous exposure from both sides during a single pass, with counter-directional initial impact to dislodge internal contamination and subsequent side impact for complete cleaning, along with transport rollers, blowing devices for air drying, and an inspection system for successful cleaning verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single spraying device is used to clean the jet strip, then the device structure is simple, but the cleaning performance is insufficient and multiple passes are required
Solution Approach 1:
The cleaning device is divided into multiple independent spraying devices (first spraying device and second spraying device) positioned at different locations. Each spraying device can independently clean one side of the jet strip, allowing simultaneous multi-sided cleaning and improving overall cleaning efficiency without requiring multiple sequential passes.
Solution Approach 2:
The cleaning approach transitions from single-sided sequential cleaning to multi-sided simultaneous cleaning by adding spraying devices at different spatial dimensions (first side and second side of the jet strip). This dimensional expansion allows the strip to be cleaned from multiple angles at once, significantly improving cleaning performance in a single pass.
2Productivity
If the jet strip is cleaned from one side only, then the device structure is simple, but internal contamination cannot be effectively removed
Solution Approach 1:
The cleaning system is segmented into multiple spraying devices positioned at different sides of the jet strip. The first spraying device cleans the first side while the second spraying device cleans the second side, ensuring that contamination on both surfaces is addressed simultaneously and effectively removing internal contamination that would otherwise remain inaccessible.
Solution Approach 2:
Instead of cleaning only from one side in a sequential manner, the invention applies cleaning action from both sides simultaneously. The second spraying device is positioned to clean the second side of the strip, effectively reversing the conventional single-sided approach and enabling comprehensive contamination removal including internal surfaces.
3Ease of operation
If multiple passes are required for cleaning, then thorough cleaning can be achieved, but the handling time and operational complexity increase
Solution Approach 1:
The cleaning device is pre-configured with multiple spraying devices positioned at different sides of the jet strip path. This preliminary arrangement of cleaning resources allows the strip to be cleaned comprehensively in a single pass without requiring multiple sequential operations, significantly reducing handling time and operational complexity while maintaining thorough cleaning effectiveness.
Solution Approach 2:
The cleaning action continues uninterrupted across both sides of the jet strip simultaneously as it passes through the device. The first spraying device and second spraying device operate continuously and in parallel, ensuring that the entire strip is cleaned in one continuous pass rather than requiring multiple separate passes, thereby improving cleaning speed and reducing operational time.
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 configuration enables complete cleaning of the nozzle strip in a single run, improving efficiency and handling by effectively expelling internal contamination and ensuring thorough cleaning, with the option for additional passes based on inspection results.
Implementation Method 1
a spraying device for water under high pressure, by means of which the strip is acted upon in the region of its openings
Implementation Method 2
the first impact occurs counter to the direction of water spray occurring during operation, ie the openings in the strip are impacted with spray water from the outside
Implementation Method 3
a suction device opposite the spraying device
Implementation Method 4
the cleaning device is assigned a blowing device, by means of which the strip, which is sprayed on both sides with spray water, can be charged with compressed air. This blows off adhering water

AI summary
The invention relates to a device for cleaning a jet strip of a hydro-entanglement device for textile fabrics, having the following characteristics: a conveying apparatus for the jet strip in order to transport the jet strip in the longitudinal direction; a spraying apparatus for water under high pressure, by means of which spraying apparatus the strip is acted upon in the area of the openings of the strip; and a suctioning apparatus, which lies opposite the spraying apparatus. According to the invention, two spraying apparatuses (DO, DU) arranged one after the other in the conveying direction are associated with the jet strip (D), wherein both sides of the jet strip (D) can be acted upon one after the other by the two spraying apparatuses (DO, DU).
