Edge Trimming Air-Guiding Cover for Scrap Removal in Edge Banding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional edge banding machines are inefficient in removing scraps produced during the edge trimming process, leading to accumulation inside the machine and attachment to workpieces, which affects machine operation and requires manual cleaning.
Innovation Solution
An edge trimming mechanism with a cutting device and an air guiding cover that uses a motor, cutter, and hollow-shaped air guiding cover with an air inlet, outlet, and exhausting path to direct scraps to a dust collecting device, preventing them from accumulating inside the machine and attaching to workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional edge trimming mechanism is used, then edge trimming function is achieved, but scraps accumulate inside the machine and attach to workpieces
Solution Approach 1:
The patent extracts the harmful scraps from the machine interior by introducing an air guiding cover with inlet and outlet channels that direct scraps outward through airflow, separating the waste removal function from the trimming operation
Solution Approach 2:
The patent employs pneumatic principles by using air flow through the air guiding cover to transport scraps from the cutting area to the exterior, utilizing gas flow to solve the solid waste removal problem
2Ease of operation
If conventional edge trimming mechanism is used, then edge trimming function is achieved, but manual cleaning is required frequently
Solution Approach 1:
The patent implements self-service by enabling the machine to automatically remove its own waste products through the air guiding cover system, eliminating the need for external manual cleaning operations
Solution Approach 2:
The air guiding cover creates a continuous airflow path that actively removes scraps as they are generated, providing real-time waste removal feedback rather than allowing accumulation
3Device complexity
If scraps are not removed, then simple mechanism structure is maintained, but scraps affect machine mechanisms and attach to workpieces
Solution Approach 1:
The patent segments the machine into functional zones by introducing the air guiding cover as a separate component with distinct inlet and outlet pathways, organizing waste removal as an independent function
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
Effectively removes scraps during the edge trimming process, preventing them from scattering inside the machine and attaching to workpieces, thus maintaining machine efficiency and reducing cleaning needs.
Implementation Method 1
The air guiding cover has an air inlet and an air outlet. An air exhausting path is defined between the inner wall of the air guiding cover and the outer wall of the motor. Two opposite ends of the air exhausting path communicate with the air inlet and the air outlet respectively.

AI summary
An edge trimming mechanism of an edge banding machine capable of removing scraps includes a cutting device and an air guiding cover. The cutting device includes a motor having a power outputting shaft, and a cutter mounted at an end of the power outputting shaft. The air guiding cover is hollow-shaped, installed outside the motor, and has air inlet and outlet. The power outputting shaft protrudes out of the air inlet and the cutter is at least partially located out of the air inlet. An air exhausting path is defined between the inner wall of the air guiding cover and the outer wall of the motor. Two opposite ends of the air exhausting path communicate with the air inlet and outlet respectively. By the above-described configuration of the edge trimming mechanism, it is effective in removing the scraps produced by the edge banding machine in the edge trimming process.
