Oscillating Hollow Drill Paper Punch Prevents Material Entrapment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper punches often result in incompletely severed material being swept along by the rotating drill, leading to unsatisfactory punching results, particularly when valuable materials like plant leaves are being sampled, and fail to punch accurately beyond the edge of the material.
Innovation Solution
A paper punch with an oscillating hollow drill that alternates between two directions of rotation, converting rotary motion into oscillating motion to prevent material entrainment, combined with a magnetic ejector and vacuum assistance for precise and controlled ejection of punched samples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotating hollow drill is used for punching paper, then punching speed is improved, but incompletely severed material is swept along leading to unsatisfactory punching results
Solution Approach 1:
The hollow drill performs periodic oscillating movements instead of continuous rotation, alternating between forward and backward directions. This periodic action allows the drill to cut through material completely by reversing direction, preventing incompletely severed material from being swept along and ensuring reliable punching results while maintaining efficient operation
2Productivity
If a rotating hollow drill is used for punching, then punching efficiency is improved, but material fibers are not completely severed causing sample loss
Solution Approach 1:
The oscillating drill performs periodic forward and backward movements, ensuring complete severing of material fibers by reversing direction. This periodic action prevents incompletely cut samples from being lost while maintaining punching efficiency, directly addressing the sample loss problem
3Ease of operation
If simple punching is performed, then operation simplicity is maintained, but paper fibers are not completely severed requiring additional operations
Solution Approach 1:
The drill transitions from static simple punching to dynamic oscillating movement, automatically performing the cutting action in both forward and backward directions. This dynamic operation ensures complete severing of paper fibers while maintaining ease of use, as the oscillation is automatically controlled by the device
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
The oscillating motion ensures complete severing of materials, preventing sample loss and allowing for accurate punching beyond the edge of the material, while the magnetic and vacuum systems facilitate reliable ejection and retention of samples.
Implementation Method 1
the hollow drill oscillates. Such a punch is therefore also referred to below as an oscillation punch. The hollow drill thus moves back and forth mechanically between two different positions. An oscillating movement during punching avoids paper being entrained.
Implementation Method 2
one or more magnets are present, which bring about the ejection movement through magnetic forces.

AI summary
The object of the invention is to provide a further developed die-cutting machine with a hollow drill bit (6) with which paper or other materials can be die-cut in a desired manner. To achieve this object, a paper die-cutting machine comprises a hollow drill bit (6) as the die-cutting tool and a drive for the hollow drill bit (6). When the drive is activated, the hollow drill bit (6) oscillates. The hollow drill bit (6) thus moves mechanically back and forth between two different positions. This oscillating movement during die-cutting prevents the die-cutting sample from being dragged along, for example, by uncut fibers. Therefore, very good die-cutting results are achieved. Preferably, the hollow drill bit (6) rotates alternately in opposite directions when the drive is activated, thus oscillating in this way to achieve even better die-cutting results.
