Rod Article Alignment via Mechanical Positioning for Consistent Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic heated-not-burn devices using induction heating, the random rotational position of the susceptor band within rod-shaped consumables during the cutting process leads to inconsistent heating efficiency, temperature distribution, and reduced performance due to potential deformation or damage of the susceptor band.
Innovation Solution
An apparatus and method utilizing a mechanical positioning system that includes a conveyor, a detection device, and a mechanical positioning unit to rotate rod-shaped articles around their longitudinal axis to a defined position, ensuring the susceptor band is aligned optimally before cutting, using a reference element for detection and rotation to maintain consistency and precision.

Engineering Contradiction Analysis
1Productivity
If rods are placed in flutes of a conveyor drum and cut by a circular knife, then cutting can be performed continuously, but the rotational position of the susceptor band inside the rod is random, leading to inconsistent cutting angles and potential damage to the susceptor band
Solution Approach 1:
The patent applies preliminary action by rotating the rod-shaped article to a defined rotational position before the cutting operation. The detection device detects the position of the reference element, and the mechanical positioning unit rotates the article to align the susceptor band at the optimal angle relative to the cutting knife, ensuring consistent cutting angles and preventing susceptor band damage while maintaining continuous production
2Ease of operation
If a magnetizing device is used to rotate articles, then the magnetic bands can be aligned to the same vertical or horizontal position, but magnetic fields interact with all magnetic or magnetisable material in the vicinity, reducing precision and reliability
Solution Approach 1:
The patent replaces the magnetic field-based magnetizing device with a mechanical positioning unit that physically rotates the rod-shaped article. This mechanical system acts only on the intended object through direct contact, avoiding interference with other magnetic materials in the vicinity and providing more reliable and precise alignment of the susceptor band
Solution Approach 2:
The patent introduces a mechanical positioning unit as an intermediary between the detection device and the cutting device. This intermediary mechanically rotates the article to the correct position based on detection feedback, providing precise control over the rotational alignment without the unwanted side effects of magnetic field interaction
