Adjustable Suction Element Sealing for Production Waste Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices for removing waste products from production machines often experience interference geometries, uneven speed and pressure fields, leading to clogging and unreliable waste extraction due to fixed suction element positions.
Innovation Solution
A suction device with a sealing means that allows the suction element to be variably positioned and adjusted along the suction chamber, ensuring reliable sealing and uniform flow, using mechanisms like roller blind seals, zippers, telescopic elements, or magnetic tapes to maintain sealing while allowing flexible positioning of the suction element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suction element position is fixed in the main line, then the device structure is simple, but interference geometries arise and waste extraction becomes unreliable
Solution Approach 1:
The suction element is made movable along the suction chamber instead of being fixed, allowing dynamic adjustment of its position to adapt to different waste product locations. The sealing means dynamically opens and closes along with the suction element movement, maintaining sealing while enabling position adjustment.
Solution Approach 2:
The sealing means is divided into multiple segments or sections that can independently open and close. When the suction element moves to a new position, only the relevant sealing segments open, while others remain closed, maintaining effective sealing without requiring the entire sealing structure to be complex.
2Reliability
If manual adjustment of suction pipes is used, then flexibility in positioning is achieved, but uneven speed and pressure fields occur leading to clogging
Solution Approach 1:
The suction element can be dynamically adjusted to optimal positions based on waste product locations, and the sealing means dynamically adapts to maintain sealing. This dynamic capability ensures reliable waste extraction without creating uneven flow fields that cause clogging.
3Adaptability or versatility
If the suction element moves along the suction chamber, then flexible positioning is achieved, but sealing of the suction chamber becomes difficult
Solution Approach 1:
The sealing means is designed to dynamically open and close along with the suction element movement. When the suction element moves to a new position, the sealing means adjusts accordingly, opening at the new position and closing at the previous position, thereby maintaining continuous effective sealing of the suction chamber.
Solution Approach 2:
The sealing means acts as an intermediary between the movable suction element and the suction chamber, enabling the suction element to move while maintaining the sealing function. The sealing means mediates the conflict between movement and sealing by providing a mechanism that adapts to the suction element's position changes.

AI summary
The invention relates to a device (1) for suctioning off waste products (2) from a production machine (3), in particular from a sheet extruder, comprising a suction chamber (10) on which at least one suction element (20) is arranged, said suction element extending into a suction space (4) located outside the suction chamber (10) in order to convey waste products into the suction chamber (10), and comprising a suction unit (5) to generate a negative pressure in the suction chamber (10). According to the invention, a sealing means (40) that rests against the suction element (20) and seals the suction chamber (10) is designed in such a way that the suction element (20) can move along the sealing means (40), thus enabling the position of the suction element (20) on the suction chamber (10) to be variably adjusted.
