Panel Cutting Dust Removal With Inward Blowing Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood or plastic panel cutting machines have inefficiencies in their blowing nozzles, which disperse processing powders and shavings into the environment, posing health risks and affecting machine operation.
Innovation Solution
The cutting machine incorporates a blowing device with nozzles mounted along the inner faces of retaining walls, oriented to direct air flow parallel to the panel surface, and additional nozzles on the outer faces of plates to collect powders and shavings within pneumatic suction cavities, enhancing containment and removal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blowing nozzles are mounted on the outer face of the plate to remove powders and shavings, then the panels can be kept clean, but the powders and shavings are dispersed into the outer environment causing health risks and machine operation issues
Solution Approach 1:
The patent inverts the conventional blowing nozzle arrangement by mounting nozzles on the inner face of the plate instead of the outer face. This reversal changes the air flow direction to move powders and shavings toward the suction device rather than dispersing them into the environment, thus maintaining panel cleanliness while eliminating harmful dispersion
Solution Approach 2:
The plate structure serves as an intermediary element between the blowing nozzles and the suction device. By positioning nozzles on the inner face and directing air flow through the plate structure, the system creates an intermediate pathway that channels powders and shavings directly to the suction device, preventing environmental dispersion while maintaining effective panel cleaning
2Device complexity
If blowing nozzles are distributed on the outer face of the plate, then the structure remains simple, but the blowing efficacy is relatively low
Solution Approach 1:
The patent reverses the nozzle mounting location from outer face to inner face, which fundamentally changes the air flow pattern and dramatically improves blowing efficacy. This inversion allows the air flow to work in conjunction with the suction device rather than opposing it, creating a more effective powder and shaving removal system without significantly increasing structural complexity
Solution Approach 2:
The patent merges the blowing and suction functions into a coordinated system where the blowing nozzles on the inner face work in tandem with the suction device. This combination creates a synergistic effect where the air flow from nozzles directs powders toward the suction inlet, significantly enhancing overall blowing efficacy compared to standalone blowing nozzles

AI summary
In a machine for cutting wood panels (2) or the like, the panels (2) are fed along a supporting surface (P) and through a cutting station (8) and are blocked in the cutting station (8) by a pressing device (13); the powders and/or shavings generated during the cut being removed from the supporting surface (P) by means of a blowing device (23) having at least one retaining wall (24a, 24b) mounted outside the pressing device (13) and provided with a plurality of blowing nozzles (28) distributed along an inner face (26) of the retaining wall (24a, 24b) facing towards the pressing device (13) itself.
