Edgebanding Machine Hot Gas Recirculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edgebanding machines for wood panels suffer from energy waste, safety hazards, and overheating of mechanical components due to the dispersion of hot gas into the environment when not in use.
Innovation Solution
Incorporation of a recirculation branch that allows hot air to be reused by redirecting it back into the system when a panel is not present, utilizing a heat exchanger or pressure adjusting devices to maintain efficiency and safety by preventing gas dispersion into the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hot gas is dispersed into the external environment when panel is absent, then the system is simple to operate, but energy waste occurs and safety hazards arise
Solution Approach 1:
The patent converts the harmful dispersed hot gas into a beneficial recirculating resource. The recirculation branch captures hot gas that would otherwise be wasted and redirects it back through the heating devices, transforming energy loss into useful thermal energy that maintains system efficiency and reduces operating costs.
Solution Approach 2:
Instead of discarding hot gas into the environment, the system recovers it through the recirculation branch. The recovered hot gas is reused to preheat incoming gas or maintain thermal conditions in the chamber, eliminating energy waste while keeping the system simple to operate.
2Device complexity
If hot gas is dispersed into the external environment, then the system structure is simple, but safety hazards for operators occur
Solution Approach 1:
The recirculation system converts potentially hazardous dispersed hot gas into a controlled recirculating flow. By capturing and redirecting the hot gas through the recirculation branch back to the heating devices, the system eliminates safety hazards while adding only a simple recirculation path rather than complex safety systems.
3Device complexity
If hot gas is dispersed into the external environment, then the outlet nozzle can be simple, but mechanical components mounted close to the outlet nozzle overheat
Solution Approach 1:
The recirculation branch ensures continuous useful action by constantly redirecting hot gas back through the heating devices rather than allowing it to disperse. This continuous circulation prevents thermal buildup near the outlet nozzle by maintaining steady thermal conditions, protecting mechanical components from overheating while keeping the nozzle structure simple.

Function Achieved in This Case
This solution reduces energy waste, enhances operator safety, and prevents overheating of mechanical components by recirculating hot air within the system, making the edgebanding process more efficient and cost-effective.
Implementation Method 1
utilizing a heat exchanger or pressure adjusting devices to maintain efficiency and safety by preventing gas dispersion into the environment
Implementation Method 2
a recirculation branch (25) which extends downstream of the outlet nozzle (17) in a feeding direction (26) of the hot air along the feeding device (16) and comprises a first segment (27) having an inlet that is connected to the feeding branch (19) by means of the interposition of a shut-off valve (28), and a second segment (29) facing the outlet nozzle (17) so as to cause the hot air fed through the outlet nozzle (17) itself to recirculate
Implementation Method 3
The gas is heated up progressively by a plurality of heating devices, which are mounted in succession along the feeding device, and is directed onto the finishing edge and/or onto the lateral profile of the panel by means of an outlet nozzle provided with a shut-off valve
Implementation Method 4
The air under pressure fed along branch 19 is heated up progressively by a plurality of heating devices 20 (in the case in point, three heating devices 20), which are mounted in succession along branch 19 itself

AI summary
A machine for edgebanding wood panels (2) or the like is provided with an edgebanding assembly (10) to apply a finishing edge (11) along at least part of a lateral profile (4) of a panel (2), and with a feeding device (16) having a feeding branch (19) provided with at least one outlet (17), which is configured to direct a hot gas at the finishing edge (11) and/or at the lateral profile (4) of the panel (2) and a recirculation branch (25; 39) to cause the hot gas fed downstream of the outlet (17) itself to be recirculated in at least one heat exchanger (31; 38) mounted along the feeding branch (19).
